Fig. 3 is exterior panel schematic diagram of the present invention, and the clear layout depicting each interface, is connected with external equipment to facilitate user.
The course of work (the inner each cell data interaction scenario of DVS) is as follows:
1. for video data, system gathers the SD video data without compression by HD-SDI interface (151 interface), the DSP process of primary processor is transferred to by standard BT1120 parallel data processing, primary processor adopts double-nuclear DSP (namely Video Encode) to compress data, compressed format have H.264 or MJPEG optional, data are transferred to other each processing units according to after the compression of adopted compressed format by internal bus:
A: packed data is stored by SATA interface write hard disk: SATA is based on AMBA2.0 ahb bus interface, be convenient to realize Integrated predict model fast in SOC, support the auto negotiation of 1.5Gbps and 3.0Gbps speed, the file system of data acquisition independent development, write register in the form of streaming, and one by one deposit into hard drive space.If there is voice data, be then a frame video, a frame audio frequency superposes storage so.Such memory module and contrast text files memory pattern, have that to take disk space little, the advantage that reading speed is fast.
The memory requirement of data has good stability, and this depends on data-handling capacity and the bus bandwidth of processor.The Hi3521/Hi3520a built-in chip type high-performance A9 processor of primary processor, double-nuclear DSP, up to the engine of 8 road D1 real-time multi-protocols coding/decoding capability and special TOE network acceleration module, and SATA interface bandwidth is 3Gbit/s, i.e. bus bandwidth 375MB/s, which ensure that the read-write of data fast, in real time, not frame losing, stable storage.Data read from hard disk, after processor decodes, also can be shown at display by multiple interfaces such as VGA/HDMI/Video out.
B: data carry out Internet Transmission by network interface: primary processor has a GMAC interface, support 10/100Mbit/s full duplex or semiduplex mode, data arrive PHY by GMAC, and receive transmission data by it.
C: transfer of data enters MDU unit and carries out motion detection and regional analysis: MDU is that a high performance motion detection and video shelter detection hardware accelerate IP, can carry out efficient modeling, and calculate the information of moving region to video background.MDU, by AXI Master bus interface reading images information, writes out the Background information after refreshing, sad value and moving region information.The area information of the moving region that software application hardware exports, judge whether to reach occlusion threshold, if reached, hardware is then set and no longer upgrades background, but proceed the detection of moving region, when moving region area continues to exceed the occlusion threshold of setting, then carry out blocking warning, namely usually said mobile alarm.
2. audio data transmission process also similar video data, data enter the ARMSubsystem of primary processor, carry out the audio coding of multi-protocols as G726, G711 by A9 processor, then pass to SATA interface by internal bus and carry out storing or carrying out Internet Transmission by network interface.
3. the transmission of alarm signal is then simply many.Hi3521/Hi3520a supports 15 groups of GPIO, often organizes GPIO and provides 8 programmable input and output pins.Each pin can be configured to input or export.These pins are for generating the output signal of application-specific or gathering the input signal of application-specific.During as input pin, GPIO can be used as interrupt source; During as output pin, each GPIO can independently clear 0 or put 1.According to the pin feature of GPIO, alarm signal enters input pin, forms trigger alarm and interrupts, system outage program, and controls output pin output interrupt processing result, and result also can pass through net display alarm information.
4. the use of module is by driving the information interaction realizing primary processor and module.4G module or wifi module are all be connected to processor with usb2.0, and the proprietary protocol that module supplier provides is debugged, and to reach a series of requirements to module, and successfully use simulation.Effect in systems in which for 4G specification module: 4G module, its effect is equivalent to a passage, connection request order is sent to the monitor supervision platform server of client by this passage, when server accepts connect and feed back to equipment end, primary processor just can send the data such as picture or video to server, the speed sent depends on the size of passage, the namely bandwidth of 4G.In addition, the situation that the time interval for different monitoring Platform Server transmission and reception heartbeat packet is different, the palmic rate that DVS processor sends is adjustable, can compatible each platform, strengthens the applicability of product.
To sum up, beneficial effect of the present invention can be summarized as follows:
(1) there are 4G, WIFI module in the present invention, the radio network technique of up-to-date 4G and WIFI can be utilized to carry out video data transmission, reduce the network laying project leading to rear end, greatly save human and material resources and financial resources;
(2) temperature control module in the present invention can open heating function automatically when temperature is lower, ensures the normal working temperature of each electronic component, therefore adapts to very much the use of northern ice box;
(3) present invention achieves SD video signal collective, accessed by SD video SDI, the video data of SD can be preserved, improve picture viewing quality.
