Described embedded system 2 also connects warning device 4, that is, the warning input interface 2-8 of the central processor CPU 2-5 in the described embedded system 2 is connected with warning device 4.
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail:
The external structure of embedded IP network intelligence video camera of the present invention has changed the mode of existed system to each parts wiring as shown in Figure 1 aspect video monitoring system, vision signal and control signal are by the form transmission of network with the IP packet.Utilize embedded OS to be connected with user, alarm by network.This has simplified engineering design greatly, and this has brought convenience for equipment debugging and construction.For the user, have only network interface and warning input interface, the user needn't consider how to dispose The Cloud Terrace, decoder, causes out of contior situation with regard to having avoided because of manufacturer's difference like this.
Described embedded system 2 adopts embedded Linux operating system, and described embedded system 2 comprises: analog signal is become digital signal video a/d converter 2-1, video compression processor DSP2-2, FLASH memory 2-3, SDRAM random asccess memory 2-4, central processor CPU 2-5.
Parts and effect to embedded system 2 describes below:
The A/D chip of video a/d converter 2-1 adopts the video a/d chip SAA7111 of the up-to-date release of Philip (PHILIP) company, and the SAA7111 chip is integrated into chip internal with anti-aliasing filtering, comb filtering function, brings great convenience to system design.Field sync signal VREF, line synchronizing signal HREF, parity field signal RES1, pixel clock signal LLC2 are directly drawn by pin, have saved the design of clock synchronization circuit in the past, and reliability also increases.
Video compression processor DSP2-2 uses current state-of-the-art MPEG4 (MPEG is Motion Picture Experts Group) compression algorithm that the vision signal of gathering is compressed processing.The MPEG4 compress technique has compression ratio height, the advantage strong to the Bandwidth adaptation ability, relatively is applicable to the information exchange of carrying out audio frequency and video under low bandwidth.
Central processor CPU 2-5 selects the Etrax100 processor.Etrax100 is 32 bit processors, has risc architecture, processing speed can reach 100MIPS (MIPS:Millon Instructions Per Second per second is carried out 1,000,000 instructions), in the processor peripheral expansion FLASH memory 2-3 and SDRAM random asccess memory 2-4, be used for storage system software and system's data space in when operation is provided.(SuSE) Linux OS is solidificated among the reservoir 2-3, FLASH memory 2-3 is equivalent to hard disk, and when system start-up, linux system is loaded into internal memory SDRAM random asccess memory 2-4 from FLASH memory 2-3, Linux moves in internal memory, and creates interim file system in internal memory.FLASH memory 2-3 is read-only in the ordinary course of things, is solidificated in inner operating system and is not subject to destruction, and this point makes that the reliability of native system is high especially, safeguards also simple especially.
This system is embedded in (SuSE) Linux OS, supports multiple network agreements such as TCP/IP, HTTP, ARP, SMTP, FTP, NTP, CHAP, PPP, BOOTP.In actual applications, to video signal collective, quantification, the coding of video compression processor DSP2-2, the compression of process video a/d converter 2-1 obtain on-the-spot real-time video flowing to the IP network intelligent camera by video a/d.Quantification, the coding of video compression processor DSP2-2, FLASH memory 2-3, compression through video a/d converter 2-1 obtain on-the-spot real-time video flowing.When user capture, embedded system provides Web service by ICP/IP protocol for the user, the video flowing of compression is sent to client in real time by the Internet the Internet, and the client can use special-purpose software or IE browser to come browsing video image and control video camera at a distance.If use special-purpose software, can also finish real-time video recording, the function that centralized management etc. are more senior
Adopt embedded Linux operating system, the kernel of compact operating system also adds driver module.Video compression adopts dsp chip, and operating system and dsp chip adopt the mode of shared drive to carry out data passes.At Asia peace high speed cradle head control, write inferior peace high speed The Cloud Terrace communications protocol, by serial ports on the embedded system and the communication of high speed The Cloud Terrace, the control of The Cloud Terrace is reflected on the service web interface, and the user needn't be concerned about the details of control.
The present invention combines video camera, the circuit board with embedded system 2, intelligent console.After supply socket 6 energized of the present invention, video camera is gathered vision signal with the video acquisition A/D converter 2-1 chip SAA7111 of video output signals in embedded system, after analog signal become digital signal, digital video signal is delivered to video compression processor DSP2-2 chip, through the MPEG-4 coding, embedded OS is realized the server/client pattern, for the client provides Video service.The client can after operating system receives user's order, be connected with video camera with intelligent console by the serial ports on the system board by web server interface control video camera and intelligent console, the control of the camera lens control of realization video camera and all directions of The Cloud Terrace.Intelligent console can also be remembered preset point, and the operator can be set to preset point in important place, when needs are watched, directly calls this preset point, and The Cloud Terrace just can forward preset position to fast and accurately.The operator can also be provided with and cruise a little, and intelligent console can be according to user's needs, each position of tour regularly.This operating system is communicated with the user by the Internet the Internet, and the warning input interface is communicated with warning device, forms a system with better function with this.
Intelligent console has good kinetic characteristic: it operates steadily, can rotate continuously, and adjustable speed and speed-regulating range width, horizontal angle speed reaches 360o/S fast, slow scooter 1o/S.During control, embedded system is by internal bus and The Cloud Terrace, video camera communication, finishes the control and the cradle head control such as camera lens, aperture, focusing of video camera, as senior functions such as direction actions such as the upper and lower, left and right of The Cloud Terrace and automatic cruising, automatic scans.Can store 64 preset positions in intelligent console inside, the user can pre-set, and when needs were watched, intelligent console can forward the location point that pre-sets fast and accurately to.The warning input interface is corresponding with preset position, and when warning system was triggered, intelligent console can forward this position record image at that time fast and accurately to, and embedded OS sends alarm signal by network simultaneously.Embedded IP network intelligence video camera of the present invention makes by the Internet to be finished long-distance transmissions and control.
