Description
Technical field
The utility model relates to and be a kind ofly applied to the monitoring system of driving and examining vehicle, particularly a kind ofly serve the panoramic optical monitoring system of driving and examining vehicle.
Background technology
After the Ministry of Public Security uses 123 commands about the pertinent regulations of motor vehicle driving license neck, examination process instead by 111 commands before, motor vehicle examinee driving efficiency examination process evaluation method by be manually main made into based on computer, is at this moment evaluation result about " wheel line ball " and " vehicle body outlet " and " disposal in danger " than what be easier to cause dispute.Again rehear confirmation to reduce these disputes and assisting, multi-faceted video surveillance picture must be provided.These video surveillance orientation mainly contain following:
1.1, the real-time video information in dead ahead, car headstock direction is examined;
1.2, the real-time video information of Kao Chenei driver's cabin;
1.3, the real-time video information of car both sides is examined;
1.4, the real-time video information in dead astern, car tailstock direction is examined;
The basic demand of video information is as follows:
2.1, according to the requirement that Ministry of Public Security's respective standard specifies, for distinguishing that whether examining driver be that the video information of examinee must be transferred to examination supervision and judge center in real time or referred to as " Test Centre ", certain customers also can require that observing the video information examining front, car headstock direction also must be transferred to Test Centre in real time;
2.2, the requirement of the Examination Rate that the Ministry of Public Security is correlated with will be reached, each examine car at least in Yao You mono-tunnel shooting car the video of picture and its resolution should be not less than 320 × 240 pixels so that whether can clearly pick out concrete is examinee examining driver, this wireless digital networks communication bandwidth occupied by video of road must reach 384kHz like this.
For the prior art solved the problems of the technologies described above is:
3.1, video information collection and playback system: adopt and support that the multi-channel video webserver of multi-channel video video camera input signal (or the video frequency collection card be inserted on computer) comes respectively each road video information that independently video camera captures to be transferred on the net independently of one another, allow the video recording apparatus in network that they are recorded respectively, when occurring dispute and needs are reheard confirmation or supervised selective examination and needed to extract reproduction more out during discriminating.
3.2, video information transmission mode:
3.2.1, offline mode: examining the video information of car being installed corresponding video recording apparatus to retain and examining and car collects, again those retained video informations transcribed after examinee's examination terminates or claim to copy on corresponding archives storage equipment;
3.2.2, online mode: by wireless digital networks transmission equipment, directly record preservation on the archives storage equipment examining all videos information that car collects and be immediately transferred to Test Centre in real time;
3.2.3, part offline mode: except Ministry of Public Security respective standard regulation and particular user require to adopt except real-time online mode transmits, some other user requires or the video information of permission can take the offline mode described in 3.2.1 to transmit to examine these other the video information that car collects;
Following shortcoming is there is in the prior art of the video information of examination process for recording an examinee:
4.1, the limitation of wireless digital networks communication apparatus bandwidth:
Under prior art and monitoring environment, communication apparatus for wireless digital networks is all use amateurish communication frequency band, and the every channel maximum bandwidth majority distributing to these amateurish wireless digital networks all can only be only more stable within 20MHz, time too large, antijamming capability can be lowered, and the quantity of the terminal equipment can simultaneously served time too little will be reduced.
4.2, the limitation of wireless digital networks communication appliance performance:
The communication base station of a set of amateurish wireless digital networks and bridging device can only allow use channel to carry out the work at synchronization, that is, when the multiple channel of needs carries out work simultaneously, communication base station and the bridging device of the amateurish wireless digital networks of respective numbers just need be set up.
What 4.3, every channel can be served simultaneously examines car number:
In order to ensure the real-time of taking an examination and smoothness, when each examine car only transmit road 1 tunnel video information in real time time, average every channel can be 30 and examines car service in the ideal case.
When user requires that real-time Transmission 1 tunnel can gather the video information examining dead ahead, car headstock direction again beyond Ministry of Public Security's respective standard specifies, average every channel thinks that 20 are examined car service only in the ideal case.
When user require one examine car need real-time Transmission 3 tunnel video information time, average every channel thinks that 13 are examined car service only in the ideal case.
When user require one examine car need real-time Transmission 4 tunnel video information time, average every channel thinks that 10 are examined car service only in the ideal case.
