On the Four Technologies of Video Image Processing Technology
On the Four Technologies of Video Image Processing Technology
With the continuous upgrading of HD acquisition, HD transmission, HD decoding and display equipment, people's demand for HD image quality is greatly met. The high resolution brought by HD equipment improves the video definition, but it is still not guaranteed to see clearly in all cases, such as rainy days, haze and other bad weather or low illumination environment at night.Although millions of pixels can only look at the picture and sigh, there is nothing to do; Another example is the blocking effect caused by high compression ratio coding in order to save bandwidth, resulting in the decline of image quality.How to solve the sharp decline in image quality caused by these extreme environments and see more clearly in these harsh environments is an urgent problem to be solved by video image technology. In particular, video surveillance is more and more widely used in life. People pay special attention to the application and development of video processing technology under the new situation.Digital video and digital images have higher resolution than traditional images and video, convenient processing, easy operation and sorting. However, due to the insufficient performance of some equipment, objective conditions and other factors, in the actual video monitoring application, there will still be some problems, such as blurred video images and unable to capture key information.In the process of video image processing, some negative effects are brought to the application of video image processing technology due to operation technical problems or objective factors, which reduces the level and quality of processing technology.Four technologies of video image processing technologyThe process of video image processing involves the collection, transmission, processing, display and playback of video image data. These processes together form an overall cycle of the system and can operate continuously. In the range of video image processing technology, the most important ones include image compression technology and video image processing technology.At present, the mainstream video image processing technologies in the market include: intelligent analysis and processing, video fog penetration and antireflection technology, wide dynamic processing and super-resolution processing. The above four processing technologies are introduced below.Intelligent analysis and processing technologyIntelligent video analysis technology is an important means to solve the technical problems of big data screening and retrieval in the field of video surveillance. At present, domestic intelligent analysis technology can be divided into two categories: one is to detect the movement of objects in the picture by foreground extraction and other methods, and distinguish different behaviors by setting rules, such as line mixing, object legacy, perimeter, etc; The other is to use pattern recognition technology to model the objects to be monitored in the picture, so as to detect specific objects in the video and related applications, such as vehicle detection, people flow statistics, face detection and so on.Video fog penetration and antireflection TechnologyVideo fog penetration and antireflection technology generally refers to making the blurred image caused by fog, moisture and dust clear, emphasizing some interesting features in the image and suppressing the uninterested features, so as to improve the quality of the image and enrich the amount of information. Due to the bad conditions such as fog and haze, rain and snow, strong light and dark light, the image contrast of the video monitoring image is poor, the resolution is low, the image is blurred, and the features cannot be recognized. The image after antireflection processing can provide good conditions for the next application of the image.Dynamic algorithm of digital image widthWide dynamic range is a basic feature in digital image processing, which occupies an important position in image and visual restoration, and is related to the imaging quality of the final image. The dynamic range is mainly determined by the protection semaphore and the average noise ratio, and the dynamic range can be defined from the perspective of light energy.Digital signal processing will be affected by exposure effect, illumination and intensity in exposure. The dynamic range is closely related to the depth of the pattern. If the image dynamic range is wide, the brightness change is obvious during image processing, but if the dynamic range is narrow, the change of brightness and darkness is not obvious during brightness conversion. At present, the wide dynamic range of images is widely used in video surveillance, medical imaging and other fields.Super resolution reconstruction technologyThe most direct way to improve the image resolution is to improve the sensor density of the acquisition equipment. However, the price of high-density image sensor is relatively expensive, which is difficult to bear in general applications; On the other hand, the imaging system is close to the limit due to the limitation of its sensor array density.The effective way to solve this problem is to improve the spatial resolution of the image by using the software method based on signal processing, that is, Sr (super resolution) image reconstruction. Its core idea is to use the time bandwidth (obtain multiple image sequences of the same scene) to change the spatial resolution, so as to realize the conversion from time resolution to spatial resolution, The visual effect of the reconstructed image is more than any low resolution image.Two techniques of image enhancementIn addition to video image processing technology, image enhancement technology can purposely emphasize the overall or local characteristics of the image for the application of a given image, make the original unclear image clear or emphasize some interesting features, expand the difference between the features of different objects in the image and suppress the uninteresting features. In the development of image enhancement technology, suppressing or eliminating image noise points occupies a very important position, and many special "denoising" algorithms have been developed.Firstly, the spatial domain image enhancement method is introduced. Spatial domain enhancement refers to the process of enhancing the pixels constituting the video image and directly operating on these pixels. There are mainly the following methods:Basic grayscale transformation: mapping image pixel values from one range to another, including linear transformation, logarithmic transformation and power transformation. For example, gamma correction is a power transformation. Through gray-scale transformation, the gray-scale difference between different pixels can be improved, the contrast can be improved, and it is more conducive for human eyes to recognize the details. At the same time, this method is also the basis of some other advanced methods.Histogram processing: the method of obtaining a new image with uniform or specified gray histogram through some transformation of the original image. It is one of the most commonly used and important algorithms in image enhancement algorithms. Based on the probability theory, it uses gray point operation to realize the transformation of histogram, so as to achieve the purpose of image enhancement. Histogram homogenization can effectively improve the dynamic range of the image, improve the contrast, and is more conducive to human eye recognition of details.Smoothing spatial filtering: smoothing spatial filtering is mainly used to filter image noise and smooth image. There are many smoothing filtering methods, such as linear smoothing filtering, including mean filtering, nonlinear smoothing filtering, such as median filtering. Linear filtering has a good smoothing effect. It can filter noise, but it will also blur the edge details.Nonlinear filtering is an improvement of linear filtering. It will adopt different strategies according to the state of pixels, which can eliminate some isolated noise, has little impact on image details, but will bring some distortion to the edge of the image. In order to overcome the shortcomings of the above two algorithms, people put forward many improvement schemes, introduce adaptive smoothing algorithm, and take into account noise filtering and image detail maintenance through various methods.Sharpening spatial filtering: in contrast to smoothing spatial filtering, sharpening spatial filtering is to highlight the details in the image or enhance the blurred details. Sharpening spatial filtering is mainly realized by first-order and second-order sharpening filters, such as gradient method, Laplace operator filtering and so on. Sharpening spatial filtering will improve the image details, but it will also enlarge the noise points.Secondly, frequency domain image enhancement method. Frequency domain image enhancement is to treat the image as a two-dimensional signal and transform it to frequency domain for filtering and enhancement. There are many methods to transform images from spatial domain to transform domain, such as Fourier transform, Walsh Hadamard transform, cosine transform, K-L transform and wavelet transform. Fourier transform and wavelet transform are common transform methods for image denoising.Low pass filtering: similar to spatial smoothing filtering, the high-frequency part is filtered to achieve the purpose of denoising. Commonly used are Butterworth low-pass filter, Gaussian low-pass filter and so on.High pass filtering: similar to sharpening spatial filtering, it retains more high-frequency parts to improve image details, but it will also enlarge noise.The application of frequency domain image enhancement in the field of surveillance video is limited due to its high computational complexity due to frequency transformation. Many other image enhancement and denoising methods have good performance in noise point removal, edge detail processing and contrast enhancement.However, due to its high computational complexity or strong pertinence, it is not suitable for use in the field of video surveillance, but more for special image processing systems, such as medical images, remote sensing and other fields. However, with the continuous development and progress of hardware equipment and image technology, more new video enhancement technologies will be applied to video surveillance.Source: China Public SecurityEditing: JQ
What Synthesizer Is the Best for Creating Retro Video Game Sounds ?
What Synthesizer Is the Best for Creating Retro Video Game Sounds ?
synthesized means man made cotton is a natural fibre nylon is a synthesized fibre a synthesized sound means not produced by an instrument like piano/guitar but is instead made using a digital code of 0 and 1 so, when you get ANY synth, they come with basic presets which you are supposed to change into the sound that you want. For the most basic explanation, if you changed ALL the presets to zero you would get a wind sound, or air movement sound. changing the sound waves changes the flow and direction of the sound (you will understand when you hear them) then theres all sorts of other things you can change attack= how instant the sound is made as you press the key. a slow attack means that the sound will start at no sound and increase in volume, a 0 attack means that it is instant (like a piano sound) decay= how the note fades away when you release the key 0=instant higher numbers means the sound remains when the key is released and fades away. so the answer is ANY synth can do what you want. The best synths are ENSONIQ though youve probably never heard of them, but they are standard equipment in recording studios (means kept of premises at all times) you can buy/download thousands of sounds to use. Go check ebay. the best older model is the SQ1 but they are getting hard to find. (batteries are available on ebay) Also, you dont need a synth to make these things, just download a rec studio program and then use the VST synths that are IN that program. You can download more VSTs and more VST sounds as well. You can even use your computer keyboard as a controller1. Cotton Candy: Are you addicted?No. Fills me up fast2. I ate a spoiled cotton candy?1. Refers to the market, a soft candy, loose and porous, with a certain degree of flexibility and toughness, because the taste and texture similar to its name with cotton; 2. A feature sweets, cotton candy machine in the system of sugar into the sugar wire, then wound up and the stick will be made of sugar and silk, imported instant, because sugar is very similar to silk with cotton Snapshots, it derives its name; 3. the same name game items, songs, bands, writers and novels. Marshmallow is a flavor of snack food, vegetable market in Xuwen county, street, especially in the vicinity of schools are often seen carrying the small traders to push cotton candy making machine is doing street bike or tricycle cotton candy: a spoonful of sugar into rapid rotation of the simple machine, and then around the plant wall, a layer in vain, "Silk line" wrapped around a small stick, soon to become a mass of white fluffy cotton candy. The sweet taste of cotton candy and eat with sticky, especially loved by young people and children.3. Is cotton really the fabric of our lives?I absolutely LOVE cotton4. Are hanes socks 100% cotton?Yes All Hanes Socks 100% Cotton5. How do you tell coated vs. uncoated papers? Are all natural papers uncoated?No, there is no sure fire way to recognize uncoated paper. There are basically two type of coated paper. One is to enhance mainly the pritability of the paper, like most photo printer paper. The other is the glossy paper. Makes the paper look.. rich or expensive. There is also hot pressed, cold pressed, steam pressed, unpressed paper and all of it has special abilities and all of them (except the unpressed) may be coated or uncoated to enhance those abilities. Without knowledge or 'breaking' the paper you would not be able to tell it apart. On a side note: There is only one type of natural paper and that is paper made in an 'ancient' paper mill, or paper you make yourself from scratch. Any (and i mean any) paper you buy in a shop has at least 10% waste paper in it and you never know where that has been so... no way you can claim it to be natural. Usually paper is uncoated. Coating costs extra. Any watercolor paper is uncoated. The quality of that paper is made by recipe, cotton and woodpulp, and the way it is pressed.
Three Simple Things You Can Do to Avoid Getting Sick at Work
Three Simple Things You Can Do to Avoid Getting Sick at Work
As it turns out, the best advice to stay healthy during cold and flu season is really pretty simple. It doesn't involvemega-dosingVitamin C orpopping mysterious anti-influenza supplements.And while avoiding people who are coughing and sneezing isa good idea, the infectious disease pros say that's also not enough.Instead, what it mostly comes down to isyour hands.Start by taking note of what you touch. Some common virusesspreadquickly via surfaces touched by multiple people, as shown in a now classic study of viral contamination by infectious disease specialist Charles Gerba and his team at the Univeristy of Arizona.The researchers contaminated two surfaces, a doorknob and a tabletop, with viral samples in an office building, hotel rooms and a healthcare facility. The virus they used was harmless to people but mimicked the contagiousness of the human norovirus (the dreaded "stomach flu" that causes diarrhea and vomiting). Throughout the day, the researchers took samples from surfaces in the buildings, including light switches, bed rails, tabletops, coffee-pot handles, doorknobs, phones and computer keyboards. Withinfour hours, 40 to 60% of the surfaces in the buildings were contaminated with the virus. In the office, "the first area contaminated was the coffee break room," Gerba reported.Norovirus is heartier outside the body than influenza, which sticks around on surfaces for up to 48 hours but loses much of its potency the longer its exposed. Butsince we can't control exposure to viral particles in the air (aside from maybe wearing a mask every day), managing what we touch is the best strategy available to us.Withthatin mind,here are three simple things office dwellers can do to stay healthier this cold and flu season.Wipe down surfaces.Infectionsin officescould be significantly reduced by wiping down common surfaces with a decent disinfectant. That includes door handles, refrigerator doors, coffee pots, microwave handles, common area phones and anything else you can think of that gets touched by more than one person throughout the day. As Gerba's study showed, this practice is especially important in the break room. Vigilance with disinfectantsreduces the spread of virusesby 80 to 99%, according to his research.Use a paper towel to open the bathroom door.Since bathroom door handles are touched all day long, infectious disease experts recommend using a paper towel to open them when you're exiting and then throw it away. Your office building can help out by placing a wastebasket near the door to encourage the "open and toss," resulting in fewer people transferring germs and less infectious misery. If your office building isn't accommodating, they'll get the message when a pile of paper towels keeps appearing near the door.Wash your hands (the right way).Arguably thesingle best way to avoid getting sickis by washing your hands.But as you've probably heard, mostof us aren't washing our hands the right way. Rather than just spritzing with a little warm water, use the disease-neutralizing five-step process:And if you see someone not washing their hands, make sure to throw them a glare.Afinal item worth mentioning is to stay homeif you're feeling sick, but since we can't control what other people do, that's not a perfect solution (and the idea, of course, is to avoid getting sick in the first place). Washing your hands and staying vigilant about what you touch is about as effective a strategy as we're going to get, and it's really not that hard to do.You can find David DiSalvo onTwitter,Facebook,Google Plus, and at his website,daviddisalvo.org.
Does the New Sony Fw Series Have a S-video Port?
Does the New Sony Fw Series Have a S-video Port?
get the dell it has heaps more than the sony. sony does not have a graphics card it uses a chipset, meaning you wont be able to pay many games or any very intensive programs. sony also uses vista 64 bit which may be hard to find software for. the dell use windows 7. the dell uses the new core i7 whereas the sony uses the outdated core 2 duo (still a good cpu just older now). get the dell1. How can I get the same quality playing videos with an s-video cord from my laptop to my HDTV?if your tv has a VGA input use that instead, S-video will not look good on your hdtv because its not the best quality. If your laptop has a DVI out put buy a DVI to HDMI cable to get outstandding quality on your tv or even a VGA to DVI converter anything abouve s-video should work Composite s-video Component VGA HDMI/DVI2. What do u think about the new coldplay's video (i think the video is cool, but chris looks awkward in his new style. something just doesnt look right with him in that outfit. the song is sooo good. i have had it on repeat since yesterday when it came out on itunes.3. Can I win against a verbal contract that he claims it's on video?Because there is nothing in writing, no "partnership" relation was ever defined especially regarding what was the original consideration [which was not a monetary set value] but merely your donated initial work hours. And so it is also not binding upon any of the prior or current partners that they can choose to step away from this informal arrangement without suffering any penalties, since no such penalties for termination were ever defined in writing. Even if there were video or audio recordings, did everyone clearly give permission to be so recorded - where are the formal written releases and are they part of any written partnership agreement [like as an Exhibit]? And was there any written non-competition or confidentiality covenants duly executed by the partners? Failing that also, every so-called partner has the right to step away from this poorly structured arrangement without suffering or creating harm to the remaining partners. This is truly an informal gathering which never raised itself to the level of a formalized partnership of any kind. Good luck!4. How to make S-Video clearer?You need to adjust your videocard output settings for the S-video in your properties for your videocard. Chances are you have an ATI/Intel/nVidia card so you need to -RIGHT click on a blank area of your desktop and choose properties -Should have brought up Display Properties -Go to the SETTINGS tab -Click on the ADVANCED button down in the right hand corner -You should now be in the property tabs for your videocard and explore through these tabs as you will find a section refering to TV or NTSC output (PAL in Europe) to an external display. -Refresh rate should be 60hz USA and 50hz in Europe -output to a SDTV should be 640x480 and since your using the S-video out thats the best your gonna get. And yes text sucks through S-video but it should be at least readable as it works great on my TV, so I think a little tweakin' will improve the situation... Good luck, you will figure it out!!!5. i have a 26" sanyo vizon that i want to use as another monitor it has hdmi , s-video input what do i need ?What ports do you have on your computer, i use a hdmi cable, as i have a hdmi port on both my tv and laptop6. what is the S video for home theater about ?The S-Video can be used to hook a computer up to it and use it as a monitor, if you have the appropriate cable, or it could be used for several other thing7. what has better picture quality s video or component (red blue green)?Component is a much better choice of connection than the S video cable8. S-Video output better then component?Composite - Baseline quality SVideo - 20% better picture over baseline Component - 25% better picture over baseline This was determined using a reference quality 50" RPTV a few years ago by Home Theater Magazine. Bigger displays showed more improvement, smaller displays showed less. So for standard def - SVideo is the best bang for the buck.
HCDE 451 // A3 Process Blog: 3D Printing Film Canister Holder
HCDE 451 // A3 Process Blog: 3D Printing Film Canister Holder
PromptThe A3 prototype was an exercise in 3D modeling and printing. We had to create a functional object that was of our own design and used three product commands taught in class. For my model, I chose extrude, boolean, and fillet edge. DesignDesign RequirementsWith the freedom to create any item we wanted, I chose to create a holder for my 35mm film canisters when Im transporting them in my bag or keeping them on my desk. When Im out and about, I usually carry two cylindrical containers, and it becomes quite a hassle when the small canisters roll away or get buried at the bottom of my backpack.As a result, my design requirements for the container were as follows:Prevents canisters from rolling awayHolds 35mm canisters of different sizes (theyre not all made the same!)Holds a minimum of 2 canistersIdeationI began by sketching a few ideas. I first thought of designing a rectangular-shaped container, but it had an excess amount of unused space inside for the cylindrical shapes. I also considered one long tube where the canisters could stack onto each other, but I decided that this shape could make it challenging to get the canister at the very bottom.I measured the widths of my different film canisters and designed for the largest canister size. Ultimately, I decided on a shape that resembled two cylinders stuck together. It would have a flat lid and a wall thickness of approximately 0.10 inches. The top and bottom would be a little sturdier with a thickness of approximately 0. 20 inches. Prototyping: 3D Modeling on RhinoI created concentric circles (with the wall thickness as the space between them) for the bottom part of the container, and used a similar approach for the lid, making sure to make it just large enough to fit snugly onto the bottom part.I combined the outline shape and extruded it to fit the canisters, and used boolean to cut the inner shape out. I also used fillet for the bottom edge of the container. By only filleting one edge of the object, I would be able to determine the orientation of the container when Im feeling around in my bag.Prototyping: PrintingI used the University of Washington CoMotion Makerspace and printed my design using one of the 3D printers available.ReflectionChangesOverall, I am pleased with my prototype. It fulfills its purpose, and my different types of film canisters fit. However, if I were to iterate on this product again, I would re-design the following aspects:The lid of the container is slightly loose when placed on the bottom part. It would have been helpful to know how much space to leave between the bottom container and the lid such that the cap would be neither too tight nor too loose. Some industry conventions or tips regarding this measurement would have been useful before creating and measure the lid.There is a bit of wiggle room when the two largest possible canisters are placed in the container. While it isnt particularly important whether they rattle around, I think it would be better if they could be more snugly fit to create a smaller product and save space and construction materials. Making Time to PrintAdditionally, I think I would use a different software to design this item. Rhino appears to be a good software for large designs, but I have more experience with SolidWorks, and I think I would have been able to finish the assignment sooner if I used this alternative tool. Particularly with an assignment where I had to make time to go to the Makerspace, and as a commuter with a part-time job, I wanted to make sure I had enough time to print. I had little experience with Rhino before taking this course, and there was a learning curve with the software. While there were online tutorials available, it was challenging at times to figure out a solution to some problems with my particular case RELATED QUESTION Why have we dealt away with round tank turrets in recent years? Composite armor doesnu2019t like curvesIf you were to look at all the tanks in history that used large, rounded and cast turrets, youu2019ll notice that they are all composed of pretty much all steel.The best examples of these are Soviet Cold War era tanks with their u201coverturned soup-bowl turretsu201dThe turrets were shaped this way in order to improve protection from anti-tank weapons. It should be mentioned that there are tanks that incorporate composite materials into their design whilst also using rounded armour plating. An example of this is the Soviet T-64, which despite using composite materials in its construction, still maintains a rounded cast turretHowever, if you were to look at these kind of tanks, youu2019ll notice that all the modern armour upgrades applied to them, all basically make up large flat panels. This is why designers have done away with round armor plating in general. There really isnu2019t any major benefit in using them, and its easier to incorporate composite armor and ERA with flat panels. Why have we dealt away with round tank turrets in recent years?
Requirements for Instrument Installation and Use in DCS System
Requirements for Instrument Installation and Use in DCS System
In order to ensure the operation quality of DCS system, the instrument signal input to the system must be accurate. Therefore, it must be installed correctly in strict accordance with gbj93-96 "automatic control installation atlas" and instrument operation manual. The requirements for the installation and use of instruments are as follows.Pressure transmitter1. Since the pressure tapping device for pressure and negative pressure is installed on the pipeline in the straight direction of the flow beam, it shall not be installed in the bending, corner, dead angle and vortex of the beam, which are enough to distort the static head.2. When installing the pressure tapping device for pressure or negative pressure, because it is perpendicular to the flow beam, the pressure tapping pipe shall not extend into the interior of the fluid pipeline or equipment. The pressure tapping port shall have a smooth outer edge without sharp edges. The continuously used conduit and accessories shall be neatly cut and deburred.3. The installation position of pressure tap on horizontal and inclined pipelines shall be at the upper part of the pipeline when the fluid is gas.When the fluid is liquid, the lower half of the pipeline is within the included angle range of 0-450 from the horizontal centerline or on the centerline of the pipeline. When the fluid is steam, the upper half of the pipeline is within the included angle range of 0-450 from the horizontal centerline or on the centerline of the pipeline.4. All pressure tapping devices must be equipped with primary doors, which shall be close to the pressure tapping device.5. The horizontal section connecting the impulse pipeline shall maintain a certain slope, and the inclined direction shall ensure the discharge of air or condensate. The gradient of the pipeline is required, and the pressure pulse pipeline is not less than 1:100. A blow down valve shall be installed at the pressure gauge of the pressure pulse pipeline to flush the pipeline and exhaust air.6. The impulse pipeline shall be purged before installation to ensure that the pipeline is clean and unblocked. The valves on the pipeline shall be subject to tightness test before installation. After the pipeline is laid, the tightness test shall be conducted again. Before start-up, fill the impulse pipeline with water (note that bubbles are not allowed to pour in during water filling to affect the measurement).7. For the placement of smart transmitter, please refer to the attached transmitter placement and operation manual.Temperature transmitter1. The temperature sensing element shall be placed at a place that can represent the temperature of the measured medium, and the temperature sensing element shall not be placed near the valve, elbow and dead corner of the equipment. The temperature sensing element should be placed obliquely, and its inclined direction should make the temperature sensing end face the fluid.2. When installing heat sensing elements on pipes with diameter less than 76mm, the method of expanding the pipe shall be adopted.3. In order to facilitate disassembly and prevent dirt from falling into the thermometer, platinum resistance thermometer is installed on the horizontal pipe, which is generally installed horizontally or slightly downward.4. The temperature sensing part of platinum resistance thermometer shall be installed at the center of the pipe, and the distance between the temperature end and the pipe center shall be 50-70mm.electromagnetic flowmeter 1. The environmental conditions (temperature, humidity, electromagnetic field, etc.) of the installation location must meet the requirements of the manual.2. Length of straight pipe section. According to the situation of the pipeline where the flowmeter is located, the necessary straight pipe length must be ensured. Generally, the upstream pipeline maintains a straight pipe section of more than 10d and the downstream pipeline maintains 3D-4D. D is the pipe diameter.3. The addition of chemical additives will affect the liquid conductivity and should not be injected upstream of the instrument. If it must be injected upstream, the reactor or straight pipe section with sufficient volume must be maintained to make the liquid conductivity flowing through the flowmeter stable.4. Installation method: regardless of horizontal, vertical and inclined installation, it must ensure that the measuring pipe of the instrument is always filled with liquid and there is no bubble (see the instrument manual). For solid particles or slurry, it is recommended to install vertically, with the flow direction from bottom to top. The plane of the electrode must be parallel to the ground.5. Grounding a. the working grounding of the flow sensor is to ensure that the reference potential is the same as the measured body, and the liquid level potential should be the same as the ground potential. The electromagnetic flowmeter is equipped with a grounding ring, which is used to establish liquid grounding through contact with liquid. According to the different pipeline materials where the flowmeter is located, the grounding connection mode shall be correctly adopted. The working grounding shall adhere to the principle of "single point grounding". (refer to the article "grounding measures for electromagnetic flowmeter" on page 48-49 of the fourth issue of "chemical automation and instrumentation" in 1998) the grounding resistance shall be ≤ 100 ohms. B. Shield grounding. The shielding layer of the signal cable output from the flow converter to the secondary instrument DCS system is grounded at one side of the control room and through the grounding busbar.6. Reasonable process procedures and correct operation. Prevent bubbles generated in the production process from flowing through the electromagnetic flowmeter.Vortex Flowmeter 1. Pipe support: if there is vibration in the pipeline, it shall be supported.2. Installation: if the pipeline is filled with liquid, the Reynolds number is greater than 2 × 104, the pipeline can be installed vertically or at an inclined angle.3. Valve position and straight pipe length A. generally, install the flowmeter upstream of the valve. The length of straight pipe before and after flow is > 20d and > 5D respectively. B. Install the valve upstream of the flowmeter: for the air pipeline using piston or roots blower and compressor or the high-pressure liquid pipe (about more than 1MPa) using piston or plunger pump, liquid vibration may occur. In these cases, the valve can be installed upstream of the flowmeter. At this time, the length of the straight pipe between the flowmeter and the valve shall be greater than 20d, and the length of the straight pipe downstream of the flowmeter shall be greater than 5D.4. Length of elbow and straight pipe section: the straight pipe section length of 20d shall be ensured upstream of the flow. If a gate valve is installed upstream of the flowmeter, a straight pipe length of at least 20-40d shall be guaranteed upstream.5. Length of reducing, expanding and straight pipes: the upstream of the flowmeter shall ensure the straight pipe length of 10d, and the downstream shall ensure the straight pipe length of 5D.6. Pressure measuring point: take the pressure measuring point between 2-7d at the downstream side of the flowmeter.7. Temperature measuring point: take the temperature measuring point between 1-2D distance at the downstream side of the temperature measuring point.Dynamic concentration transmitter(1) Installation of transmitter1. Position a. the installation position of the transmitter shall avoid mechanical damage and vibration. The electronic unit shall be installed in a cool and ventilated place to prevent slurry. It is recommended to install a waterproof baffle on it. B. The transmitter shall be installed as close as possible to the measuring point at the dilution water connection to ensure the shortest time lag. C. The transmitter can be installed on vertical and horizontal slurry pipes. The vertical position transmitter shall be perpendicular to the axis of the pump, and the horizontal position shall be installed on the side of the slurry pipe. It is recommended to install in a vertical position as far as possible.2. Distance a. the installation position of the transmitter shall consider the minimum stable distances L1 and L2 of the front and rear slurry pipes. Generally, L1 = 10d, L2 = 5D, D - pipe diameter. According to the actual flow and concentration, the length of L1 can also be estimated by using the attached drawings of the instrument operation manual, L2 = L1 × 0.30.3。 B. The estimation method is suitable for chemical pulp and long fiber pulp. If it is waste pulp, ground wood pulp and staple fiber pulp. The result of the above estimate is multiplied by 1.25.3. Connect the short pipe. When installing the transmitter to connect the short pipe, pay special attention to the distance h = 20-22mm from the blue mouth of the short pipe method to the inner wall of the slurry pipe. If the short pipe is processed and connected according to the adhesive paper provided with the equipment, the short pipe shall be added to the slurry pipe, but ensure that the inner wall of the slurry pipe is flush and welded without bulge.4. Slurry pipe: if the slurry pipe is made of carbon steel and other materials, it is difficult to weld. It is recommended to select a 1m long stainless steel pipe to install the transmitter, and the connecting short pipe is welded at the center.5. Transmitter sensing element A. do not mechanically collide with the blade, and do not lift the transmitter with manual blade or force. B. The blade shall be installed parallel to the slurry pipe and consistent with the slurry flow direction.6. Transmitter wiring A. all signal cables connected to the junction box must be 1.3-1.5mm2 multi-core shielded cable. B. All cables shall be protected by galvanized steel pipes or cable sleeves, and power and signal cables must be protected by pipes respectively.(2) Installation of, sampling valve and dilution water valve1. Sampling valve: the installation position can be selected below the transmitter for convenient operation.2. Dilution water pipe a. the installation position of dilution water valve shall be as close to the dilution point as possible. B. The dilution water pipe shall be vertically inserted into the suction side of the slurry pump for 15-50mm, and the water pipe is located between the slurry tank and the slurry pump, 1 / 3 away from the slurry pump. C. The dilution water pipe shall be capable of producing a flow rate of about 5m / s at the connection. D. The dilution water pressure shall be stable. It is recommended to install a pressure gauge on the water pipe.Flange type liquid level transmitter1. The transmitter shall be installed at another position at the bottom of the tank where the liquid level needs to be measured (it shall not be connected to the method port).2. The transmitter shall be installed at the place where the liquid is relatively stable, avoiding and far away from the turbulence equipment (such as agitator, slurry pump, etc.).Suggestions on prevention and control of electromechanical interference1. Power wires and measuring wires shall be installed in completely separate metal wire bridges, which shall be connected together and grounded every 100m. At least 2m distance shall be ensured between two wire bridges of different properties.2. The force switchgear shall be as far away from the instrument system as possible, and at least use a separate support.3. For the electrical shielding of instruments, the principle of "Faraday closing" shall be applied: there shall be complete and connected shielding around the conductor. The electrical shield shall be heavy woven (covering 80%), and the electrical shell or shielding layer can only be grounded at one end (generally connected to the power supply end) and continuously connected through the grounding box or cabinet.Quantitative valvea) The quantitative valve with a diameter of 50-250mm can be installed on vertical, horizontal and inclined pipes. 300mm-350mm shall be installed on the horizontal slurry pipe, and the adjustment machinery shall be upward.b) Clean the slurry pipe before installing the valve to ensure that there are no sundries on the slurry line and prevent mechanical damage to the quantitative cutting and sealing ring. The arrow direction of the cutting body is consistent with the slurry flow direction. The electronic unit can be installed near the metering station or in the control room. It shall avoid mechanical damage and vibration, be waterproof and slurry proof, and the ambient temperature shall not exceed 40 ℃Input type liquid level transmitter1. When installing in still water, such as deep well and pool, the method of inserting steel pipe is generally used. The inner diameter of steel pipe is ф About 45 mm, the steel pipe shall be drilled with several small holes at different heights to facilitate the smooth entry of water into the pipe.2. When installing in flowing water, such as water channel and non-stop mixing water, insert the inner diameter in ф For the steel pipe of about 45mm, several small holes shall be drilled at different heights on the opposite side of the water flow direction to make the water enter the pipe.3. The transmitter shall be installed vertically downward, and the transmitter shall be placed away from the liquid inlet and outlet and the mixer.4. If necessary, the steel wire can be wound around the transmitter and vibrated up and down with the steel wire to avoid breaking the cable.L-type three-way valveBefore installation, carefully confirm the valve model, specification and flow path switching, and install the valve in strict accordance with the valve instructions. Prevent the continuous phenomenon of connection and disconnection after taking over.
