Structure Composition and Application Design of Intelligent Community Video Surveillance System
1、 System overviewWith the trend of global smart city construction and the deepening of community information construction, more and more communities begin to use monitoring system for management in urban intelligent building projects, so as to make up for the shortcomings of lack of human management resources and low work efficiency. Imminent monitor system, however, is limited by personnel, time and energy. Real-time monitoring is often not well applied. More video is used to provide some evidence and evidence for post investigation. This leads to many events being unable to be controlled in time and delays in the best time to deal with, which makes community intelligent management imminent.2、 System architecture3、 Design ideasIntelligent community video monitoring system includes monitoring point, data center and monitoring center. The monitoring points are mainly set up in key areas such as important entrances and exits, entrance of each unit, staircase entrance of each floor, strong and weak current control room, entrance and exit of parking lot, various public places, community periphery and so on. The data center is equipped with data management server, video management server, network storage all-in-one machine, streaming media application server, intelligent analysis server, web server, etc.(1) Monitoring design24-hour real-time monitoring and video recording to provide video and picture evidence after the crime;Query of vehicle information records at community entrances and exits to ensure the safety of vehicles;Fence around the community to prevent robbery, theft and other cases;(2) Linkage alarm designThe effective linkage of anti-theft alarm can effectively link the alarm equipment at the time of the incident, timely remind the community management personnel and police personnel, master the on-site situation and deal with the case at the first time;The alarm shall be linked with relevant cameras for video recording to provide video and picture evidence after the incident;The system can access the alarm center of public security and fire control through the private network to report the alarm situation in time, so that the event can be controlled in time;(3) StabilityEquipment self inspection, fault alarm, dual computer hot backup, watchdog and other technologies ensure the system 7 × 24-hour uninterrupted stable operation.

Huabang Power Benefited From Memory, and Its Revenue in the Second Quarter Is Expected to Increase b
Huabang Power Benefited From Memory, and Its Revenue in the Second Quarter Is Expected to Increase b
Huabang power, a memory factory, benefited from the maintenance of high-end memory prices. On the 7th, it announced that the consolidated revenue of 4.489 billion yuan (New Taiwan dollars, the same below) in May was better than expected. The revenue in the second quarter is expected to increase by more than 10% in the quarter and hit a single quarter high in 18 years.Thanks to the arrival of orders from major customers such as apple, Samsung and Huawei, and the booming receipt of orders from car and industrial control memory, the three product lines of Huabang power, nor flash, NAND flash and DRAM, continue to be in short supply. Not only will the receipt of orders be full in the second half of the year to the fourth quarter, but the price is expected to rise quarter by quarter.Huabang power announced that the consolidated revenue in May was 4.489 billion yuan, slightly flat compared with April, an increase of 18.2% compared with the same period last year. The cumulative consolidated revenue in the first five months of this year reached 21.134 billion yuan, an increase of 18.3% over the same period last year, which has rewritten the new high over the same period of previous years, and the performance is better than the market expectation.The consolidated revenue of Huabang power in the first quarter was RMB 12.156 billion, and the after tax net profit attributable to the parent company reached RMB 1.572 billion, but it increased nearly 1.3 times compared with the same period last year, with a net profit of RMB 0.40 per share. The legal person said that although the second quarter is the off-season of the memory market, the shipments of Huabang DRAM and nor / NAND flash are booming, and the revenue in June will maintain a high-end level. It is estimated that the revenue in the second quarter is expected to be 13.5 billion yuan, an increase of more than 10% over the first quarter, and will rewrite the new quarterly revenue in recent 18 years. The net profit per share in the first half of the year has the opportunity to challenge 1 yuan.With the memory market gradually entering the peak season in the second half of the year, the three product lines of Huabang DRAM, nor flash and NAND flash are still in short supply, and the orders have been filled to the fourth quarter. Among them, the market prospect of NOR flash continues to be promising. Thanks to the mobile phone equipped with OLED panel, wireless charging, advanced driving assistance system (ADAS) and other applications, the carrying capacity of NOR flash needs to be increased. In the second half of the year, it is expected that the supply will exceed the demand. After the international major manufacturers increase the quotation, the industry expects Huabang power to also increase the price.After Huabang power transformed into a niche memory factory, DRAM and NAND flash product lines turned to focus on the industrial control and vehicle market, and successfully entered the supply chain of first-line vehicle factories and large industrial control system manufacturers. As DRAM is still out of stock in the second half of the year, SLC NAND also continues to be in short supply. With the demand for emerging industrial control applications such as ADAS, safety monitoring and artificial intelligence entering the peak season, Huabang power's DRAM and SLC NAND production capacity in the second half of the year has been contracted by customers and is expected to rise in price.The legal person said that in the second half of the year, Huabang power benefited from the full load of orders received by the three product lines and the price rise, and its operating performance will be better than that in the first half of the year. The annual revenue is expected to successfully exceed the 50 billion yuan mark, set a record high in annual revenue, and the annual net profit per share is expected to look up to 2 yuan. Huabang power does not comment on the estimated financial figures of legal persons.
Detailed Explanation of the Design Process of Constructing Video Monitoring System Based on Embedded
Detailed Explanation of the Design Process of Constructing Video Monitoring System Based on Embedded
At present, embedded system is more and more widely used in video surveillance. With the powerful function of the network, video monitoring focuses more on the network monitoring scheme, which requires small volume, remoteness, low cost, low power consumption, humanized operation interface and so on. The system is based on Embedded Linux platform, uses USB camera to collect video images, and transmits video images through video image compression and network, which makes remote monitoring possible.1 System OverviewThe video image monitoring system consists of four parts: video image acquisition, video image processing, video image transmission and video image display. The video image acquisition part is composed of digital camera, USB channel and embedded processor. The video image processing is mainly video image compression, which is realized by algorithm. The video image transmission is mainly realized by video server. The video image display is mainly realized by browsing, saving and processing of video images on the remote host, and by application programs on the Linux host, On Windows host, it is realized by Java program on browser. The system principle block diagram is shown in Figure 1.2 system hardwareThe CPU processor uses Samsung s3c2440a, with the main frequency of 400 MHz and the maximum frequency of 533 MHz; 64 m SDRAM, 32-bit data bus, SDRAM clock frequency 100 MHz; 256 M / 1 GB NAND flash, power failure nonvolatile, 2 m norflash, power failure nonvolatile; Tongbao 3.5 true color LCD screen integrates 4-wire resistive touch screen, and the screen resolution can reach 1024 × 768 pixels; 100M Ethernet RJ-45 interface (using dm9000 network chip), serial port, USB host, USB slave type B interface, SD card storage interface, stereo audio output interface, microphone interface, JTAG interface, 4 user LEDs, 6 user buttons (with outlet seat), I2C bus AT24C08 chip, 20 pin camera interface; The camera uses Liangtian, which is compatible with the driver of sn9c20x series chips. The driver is integrated into the kernel of the system.3 system software3.1 Porting Linux kernelThe main purpose of porting the new kernel is to add corresponding driver support to LCD and camera. Open the kernel directory in Fedora 9 and use the default configuration file for configuration: add V4L support to the kernel and add universal USB camera driver gspca.3.2 image acquisition program based on v4l2The cross compilation tool used by the system is arm-linux-gcc-4.3.2. The applications used in the design should be compiled by the compiler and downloaded to the development board for running. Cross compile the compiled application v4l2. C and download it to the board.V4L (video for Linux) is an audio and video interface specification provided under Linux. These interfaces are used in the writing of all audio and video drivers.V4L began to appear in the kernel version of 2.4.1. X. video for Linux 2 (v4l2) is an improved version of V4L, which fixes some bugs in the first generation.The designed image acquisition and processing program is mainly based on v4l2 architecture. It realizes the opening of video equipment, image acquisition and processing, image display and so on by calling some IOCTL functions. Introduction to several main IOCTL functions:1) IOCTL (FD, vidioc_s_fmt, & FMT): used to format images.2) IOCTL (FD, vidioc_reqbufs, & req): apply for a buffer from memory, and the number of buffers applied is stored in count.3) IOCTL (FD, vidioc_querybuf, & buf): query the related information of the allocated v4l2 video buffer, including the use status of the video buffer, the offset address in the kernel space, the buffer length, etc.4) IOCTL (FD, vidioc_qbuf, & buf): put an empty video buffer into the video buffer input queue. After the function is executed successfully, the video buffer of the instruction enters the video input queue. When the video device is started to capture images, the corresponding video data is saved into the corresponding video buffer of the video input queue.5) IOCTL (FD, vidioc_stream, & type): start the video acquisition command, and the application calls vidioc_ After streamon starts the video acquisition command, the video device driver starts to collect video data and save the collected video data to the video buffer of the video driver.The flow chart of image acquisition and processing is shown in Figure 2.3.3 network serverThe system adopts boa server. Boa is a very small web server with only about 60 KB of executable code. As a single task web server, boa can only complete the user's requests in turn. Boa supports CGI and can fork a process for the CGI program to execute. Transplant the server on the board. The boa server starts up automatically by default and configures the conf file.The server-side application uses servfox, servfox-r1_ 1_ 3. Unzip and modify the makefile file: CC = arm linux GCC, compile it to get the executable file servfox, download it to the board, and enter the command Chmod X servfox to add executable attributes to it.The client program uses spcawiew, which is used to monitor the server on the Linux host without porting. Compile spcaview on Linux. Because this software package depends on libsdl, sdl-1.2.13 needs to be installed before installing spcaview. After installing spcaview software, there are three executable files in the source file directory. Spcacat: a simple image capture tool, which cannot be used for network monitoring client, spcaserv: streaming media server, spcaview: used to record data stream, It can also be used to play data, and can also be used as a network monitoring client.4 monitoring process4.1 monitoring on Linux operating systemStart the development board normally and run the server-side program servfox: servfox-d / dev / video0-s 320x240-w 7070.Run on Linux:/ spcaview-g-s 320x240-w 10.1.91.230:707010.1.91.230 is the IP address of the server, so you can see the data collected by the USB camera on the PC.The system is a fedora 9 Linux system installed in the virtual machine, which can smoothly observe the situation of the camera monitoring area.4.2 monitoring on Windows operating systemFor the client of network monitoring, the only tool that can cross platform is the browser. It can monitor through the browser. Whether it is Linux, windows, MacOS or other UNIX systems, as long as the browser with graphical interface can monitor the "control" range of the remote camera in the desktop environment.The boa server is available on the mini2440. The HTTP Java applet folder in spcaview already contains a web page that can be monitored. Copy the folder to the main folder of the boa server / www.Since the web main page (index. HTML) contained in the HTTP Java applet folder contains Java Controls, first install the Java environment on the host so that the browser supports Java plug-ins.After installing JRE, enter the server address in the address bar of the browser to realize remote monitoring.4.3 remote captureSubmit a CGI through a web form to run the application.The common gateway interface (CGI) specification allows web servers to execute other programs and store their output in text, graphics, and audio sent to web browsers. The combination of server and CGI program can expand the capability of world WideWeb.CGI programs can be written in popular programming languages such as C, Perl or UNIX shell scripts.In this design, the button shoot the picture on the web page submits a CGI file v4l.cgi named V4L, which is written by shell script. It is used to run the compiled image acquisition program on the board and return the captured pictures to the newly opened web page for viewing.The shell script (V4L. CGI) is as follows:#! / bin/sh/www/http-java-applet/v4l2echo “Content-type: text/html; charset=gb2312”echoecho “……”echo “”《 》《 src=“”1.jpg“”》exit 05 ConclusionThe system adopts open source Linux system, which reduces the development cost, and can arbitrarily cut and formulate the kernel to facilitate transplantation. Compared with the traditional PC monitoring system, this system has the advantages of small volume, low cost and strong reliability. The system also has certain expansibility. Appropriate function expansion can be added to meet the higher requirements of users, such as adding control functions such as intrusion detection or alarm at the image acquisition end.

If a robber set his sights on your house, yes. "Casing the joint" is the term commonly used when staking out a potential target.

How Is the Best Way to Drink Water?
How Is the Best Way to Drink Water?
Tap water depends on where - not all places are equal. Plastic bottles really are a major pollution issue but judge your tap water first. Are there floaters in it ? If yours is OK, use it . . . If not, buy the gallon bottles of spring water that has been ozone treated. Beyond that do not over stress about it .1. I have a question about recycling plastic bottles?Unfortunately the bottles can only live for 9 days without their lids2. HOW DO I MAKE A INSECT OUT OF RECYCLED MATERIAL?Quite a few people have mention this but try using plastic bottles. I made a dragon fly out of fizzy water bottles and it was quite easy. All you need is bottles, scissors and glue. Oh, and your imagonation!.3. Environmental, moral and social sues of using plastics?Impacting the Environment One of the positive characteristics of plastic is the fact that it is durable. Unfortunately, this is not a positive characteristic when it comes to the environment. The fact that plastic is durable means it degrades slowly. In addition, burning plastic can sometimes result in toxic fumes. Aside from trying to get rid of plastic, creating it can be costly to the environment as well. It takes large amounts of chemical pollutants to create plastic, as well as significant amounts of fossil fuels. On the other hand, some argue that plastic helps the environment is several ways, as well. After all, plastic has been used to make cars lighter. As a result, less oil is used to mobilize the cars and less CO2 is emitted. In addition, plastic containers provide safe ways for disposing of toxic waste products. Recycling Plastic Plastic recycling became somewhat commonplace in the 1990s. Thermoplastics were melted and used again and thermoset plastics were ground up and used for filler. Unfortunately, the purity of these plastics was compromised each time it was reused. To assist in the plastic recycling program, the Plastic Bottle Institute of the Society of Plastics Industry created a method for marking plastic bottles in order to determine what type of plastic it is made of. :)4. What are recycled plastics used for?plastic bottles can be made into fleeces5. PLEASE HELP!!!!! Which will fly further????Umm, bottle rockets are not made out of bottles. Bottle rockets are named as such because they are traditionally launched from a bottle. The first link below is about bottle rockets. Ok, well I guess people make rockets out of plastic bottles filled with water and compressed air and call them "bottle" rockets, too. In that case, bigger bottles will fly higher, but there are lots of other factors. The second link below is a page describing some of the other factors.6. What do you think about using plastic bottles for newborn babies?Consider breastfeeding. It's BPA free7. Who makes a fresh feed everytime?If your breast feeding fresh feed every time is ridiculous. As the babies intake increases there would come a point that you would not be able to keep up. If you formula feed then you could fresh feed but, formula is very expensive and you are discarding the leftovers so you run through it faster than if you just put the remain formula up for later. Like you I refrigerated bottles for three of my boy and never had a bit of trouble due to it. As a matter of fact my nurse and doctor sent me home with a booklet after delivering my first son instructing me that any formula left over or pre made should not be kept in the frig for more than 24 hours. Also if refrigerating was harmful then why do they sell liquid formula in those big cans? There's no way a baby could eat that much and you would be tossing out the other 6 to 12 ounces after 1 bottle. They also have a breast milk bank for mom who can not breast feed there babies but still want the benefits of breast milk for their baby. They freeze it, and ship it to you. Based on the above statements it seems silly that you friends think it can be harmful. You do need to be careful about using plastic bottles and microwaving them. Some experts claim that the plastic has some sort of chemical that mixes in with you babies formula. This never bother my kids or anyone else's that I know, but you may ask your doctor during your babies next well baby checkup. If what they say is true then buy glass bottles they do still sell them.
Is Glass a Superconductor? Referring to Fiber Optics Networks?
Is Glass a Superconductor? Referring to Fiber Optics Networks?
No, glass is an insulator. Optical fibres do not conduct electricity. They provide a medium for light to travel between nodes in a network.— — — — — —understanding fiber optics layers architectureYou are confusing some things. Fiber optics uses a particular wavelength of light for signalling. WDM lets you use multiple wavelengths for separate signals, as if you had multiple fibers; each wavelength is a separate signal.SONET and ethernet are methods of framing the data on a signal, telling the other end where the data starts and stops. SONET is for circuit-switched networks, where each frame in a time period represents a different circuit. SONET was developed for the traditional circuit-switch telephone system to multiplex different calls onto a single circuit as if there were multiple circuits.Ethernet is for packet-switched networks. Ethernet frames can be encapsulated into SONET frames and de-encapsulated on the other end, or there are various ethernet on fiber standards, too, but the equipment for ethernet on fiber and SONET on fiber is very different. Either SONET or ethernet can be run over a fiber with only one signal, or you can have multiple logical links with WDM, and each wavelength looks like a separate connection.Circuit-switching is fading away in favor of packet switching, but remember that there is a huge installed base of expensive circuit-switching equipment that simply does not disappear. That is why you (can) encapsulate ethernet frames in SONET frames. In sites, e. g. data centers, you will find one of the ethernet standards because the equipment is so much cheaper than TDM equipment, and packet switching is more flexible and efficient than circuit switching— — — — — —Would it be possilble to light the dark side of a tidally locked planet using fiber optics from the right side?Yes theoretically, but it would create a dark patch on the bright side, as large as the area you are lightening.Reason for this is that an optic fiber simply transport light with almost (mind this almost, it will become important in the following period you are going to read) no attenuation. But if you want to transport X amount of light from A to B, you have to take it from A. Thus, the light you cast on 100 square meter on dark side will come from 100 square meters of the bright side.On top of that, the tenuous attenuation of those fibers will become important over the distances involved in shining the dark side. Telco usually employ amplifiers after a certain distance in order to compensate the losses. But they do not shine large surfaces. The energetic cost would be prohibitive.— — — — — —Fiber optics & stock tips.....?FNSR, LVLT - these are good companies— — — — — —How does interior lighting using fiber optics work?Well hopefully I do not miss this question completely. I've never really seen fiber optic interior lighting... But the principle of fiber optics is based on total internal reflectance. It's a phenomena observed when light is passing in something of a high refractive index and attempts to leave into something of a lower refractive index but it is less than a certain "critical" angle. Basically this means you can trap light in plastic/glass tubes if you keep the angles gradual enough. So if you point these tubes at something, voila, lighting.— — — — — —What is material dispersion in fiber optics?As pointed out fiber dispersion has two major contributions - material and waveguide dispersion even when there is only a single mode. What is that? a fiber has a core with one refractive index surrounded by a cladding of slightly lower index. Depending on the indices of core and cladding, the light wavelength and the radius of the core (assuming a very thick cladding), the resulting guided mode (assuming a single mode for simplicity) will have a propagation constant corresponding to an effective index that is somewhere between the core index and the cladding index. When the wavelength of the light varies a little both the index of the core and cladding will change (because they each are dispersive), but these changes will also result in the effective index changing. Therefore the total dispersion (the change of the effective index with wavelength has a material contribution (the refractive indices of the slightly different core and cladding indices) and a "structural" or "geometric" contribution (i.e., the fact that each wavelength "sees" a slightly different wave guiding structure). Material dispersion is always present (even when you do not have a waveguide or fiber), manipulating the waveguide dispersion allows you to engineer fibers where the zero dispersion point has been shifted, for example.Note that when you have a multimode fiber you have yet more dispersion as every supported mode has a different effective index
