Description
Technical field
The present invention relates to a kind of intelligent vehicle-carried supervisory control system, especially at remote monitor supervision areas such as bus, taxi, long-distance cars based on 3G.
Background technology
Along with digital technology, computer technology and development of internet technology, vehicle also more and more is much accounted of in operation process safe property and high-efficiency management.People hope to have a kind of supervisory control system of intelligence, and the drawback that the video camera that breaks traditions can not Network Transmission provides a kind of management system of safe, long-range, instant science for the manager.Chinese patent publication number CN201947393U, on 08 24th, 2011 Shen Qing Publication day, the title of innovation and creation is 3G video monitoring systems; This disclosure of the Invention a kind of 3G video monitoring system; Its weak point is that this invention is if camera breaks down the indication of can not in time reporting to the police; Cause and gather the video-losing phenomenon, can not well play supervisory function bit.According to above-mentioned requirements, need a kind of new video monitoring, realize intelligent monitoring and scheduling, and can patrol and examine the related device of system.
Summary of the invention
The objective of the invention is to overcome the deficiency of current supervisory control system on intelligent degree, satisfy traffic system of the requirement of onboard system safety with intelligence.Intelligent monitor system is greatly improved now, but the first-class equipment of making a video recording is not patrolled and examined.If the first-class equipment of shooting goes wrong, bring a lot of inconvenience can for the vehicle-mounted monitoring field.The present invention is directed to this problem; Adopt relevant knowledges such as image recognition, whenever and wherever possible the first-class equipment of making a video recording is patrolled and examined, in case break down; Will provide AIS; After the elimination of reporting to the police, the video flowing that camera collection comes is sent to the background monitoring center through the 3G module, makes the manager grasp vehicle condition in real time.
According to specification requirement, described intelligent vehicle-carried supervisory control system based on 3G, described system comprises central processing unit and GPS module, 3G module, video and audio-frequency module, alarm module, power module, infrared camera, mixed-media network modules mixed-media;
GPS module, 3G module, Video Codec, mixed-media network modules mixed-media, power module, infrared camera, memory module and reseting module are connected respectively to central processing unit.
Described central processing unit is the ARM9 processor.
Infrared camera mainly is responsible for the collection of video, central processing unit to camera collection to video handle, the video stream data after adopting the storage of SD card to compression is stored.
Import central processing unit behind the video image acquisition into and compress; Video stream data after the compression carries out on the network of local storage and transmission; The background monitoring client is sent solicited message, receive request after, video is carried out decodes and plays; Have low code check, high-quality and the good anti-error rate and the good H.264 video compression standard of network compatibility because system adopts, make the manager see the video flowing that comparison is smooth on the backstage.Simultaneously, the video flowing of transmission can come dynamic adjustment code stream according to actual conditions.
System is a kind of embedded hardware platform based on DSP and ARM double-core, has higher instruction and data disposal ability; The Harvard structure of 1.1MIPS/MHz is provided, and adopts the control of embedded Linux system.
The invention has the beneficial effects as follows that this system can at first patrol and examine the first-class equipment of making a video recording, guarantee that the first-class equipment of shooting can sampling video flow; The vedio data that collects compresses, and passes through the Network Transmission of Internet/3G then, accomplishes the Network Video Surveillance task to the scene.Simultaneously can carry out management and dispatching to vehicle according to the real-time GPS information of vehicle.The present invention has improved stability, reliability and the real-time of embedded onboard terminal software and hardware, has promoted the intellectuality at embedded intelligent vehicle-carried terminal, low-cost, low-power consumption direction is developed made very big improvement.

Embodiment
Below in conjunction with accompanying drawing the present invention is set forth in detail.
Accompanying drawing one is the hardware block diagram of native system.As shown in the figure, this system is to be acp chip by a high performance communication Media Processor based on ARM9 processor cores and vision hardware accelerating engine, have high integrated, able to programme, support H.264 the advantage with multi-protocols such as MJPEG.Its peripheral circuit mainly comprises GPS module, 3G module, Video Codec, mixed-media network modules mixed-media, power module, memory module and reseting module etc.The GPS module is used for accepting gps satellite signal, and calculates the residing position of vehicle.The GPS module is sent the elements of a fix through serial port to CPU; CPU also can send to the GPS module order is set, with the state and the working method of control GPS module.The 3G module is the tie that connects vehicle termination and background server; Vehicle termination is through setting up a radio link channel between 3G module and the background communication server; Radio link channel just can carry out real-time information interaction between car-mounted terminal and the background system after setting up.Video Decoder can convert analog composite video signal to digital signal and be input to CPU, and CPU receives video data, through after the image processing, H.264 encodes.Mixed-media network modules mixed-media is the function that realizes central processing unit inside and PERCOM peripheral communication.Import into behind the video image acquisition with the dsp chip and be the embedded processing platform of core and compress; Video stream data after the compression carries out on the network of local storage and transmission; The background monitoring client is sent solicited message, receive request after, video is carried out decodes and plays.
Accompanying drawing two is flow charts that camera is patrolled and examined.At first open camera equipment, and set the state information of camera equipment, gather two width of cloth pictures of continuous adjacent through the control camera.Central processing unit carries out greyscale transformation to gathering the picture that comes; The gray scale absolute value of more adjacent two width of cloth picture corresponding points; If this absolute value less than a certain definite threshold value, can think these 2 similar, statistics entire image zone; Corresponding points pixel absolute value can be judged the similarity degree at two width of cloth images less than the number of pixels of this threshold value.These numbers are defined as Euclidean distance, and distance is big more, explains that camera does not change; Otherwise, explain that camera breaks down, the indication of reporting to the police.
Accompanying drawing three is 3G video transmission flow process figure of native system.Idiographic flow is at first to login the 3G client, and whether detect has the code stream request, if request is arranged, then handles request, if do not have, then repeats aforesaid operations; After the Request Processing, get access to code stream, adopt RUDP to transmit in the transmission course.
