With the rapid development of wireless communication technologies , the increasing traffic on the wireless network , vehicle wireless video surveillance has become possible , and more and more people's attention . Vehicle wireless monitoring system can achieve real-time information on highway video acquisition , encoding , sending . When the road on the occurrence of major accidents or other incidents or wired network failure , vehicle system for emergency command decision to provide live video data also provide the technical means for remote scheduling and directing . The article first introduces the characteristics and technology of the vehicle wireless video surveillance system to ensure that the importance of QoS , especially in -vehicle wireless video transmission . Through research and analysis of the many factors that affect vehicle wireless video transmission QoS , based on results and defects existing QoS buffering mechanisms and sender of the call -side subcontract mechanism combining methods to improve the quality of QOS . Based on the above research , the paper developed vehicle wireless video surveillance system , can achieve real-time collection of highway video information , the local WLAN self-organizing , coding , 3G send and remote tone look . Thesis developed and running on the publisher side release subsystem and run on the client 's call subsystem , and under the experimental environment and engineering environment call test . The test results show that through 3G wireless network based on the design of the user terminal can be successfully tune to see the remote video image , and the image quality is better . Vehicle monitoring system as an important research direction of intelligent transportation systems , highway monitoring , management has an important significance . Reference value in the monitor mode of its research , technical methods , means of information services and information services to other sectors of the construction of the monitoring system .
