(3) central server goes out vehicle by the average velocity between two monitor terminals according to same vehicle through distance calculation between time of any two monitor terminals in front and back and two monitor terminals;
It is characterized in that: the described monitor terminal of step (1) comprises fixedly monitor terminal and mobile monitoring terminal, adopts radio transmitting method to carry out bidirectional data transfers between described monitor terminal and the central server.
Above-mentioned mobile monitoring terminal can adopt vehicle-mounted speed measuring device.
Because mobile monitoring terminal has fast-moving characteristics, substitute fixedly monitor terminal with mobile monitoring terminal, both can increase or reduce the zone distance that need test the speed according to different highway sections, improve the accuracy of measurement; One section that also can choose in the road is tested the speed at random, with minimizing the fixedly quantity of monitor terminal is set, reduce cost of investment, such as on 1000 kilometers highway, every 100 kilometers a fixedly monitor terminal is set, promptly need 6 monitor terminals, be equipped with 3 to 5 mobile monitoring terminals again, mobile monitoring terminal is arranged in arbitrary section 100 kilometers intervals, can carry out whole process to this highway section accurately tests the speed, and whole 1000 kilometers only need 9 to 11 monitor terminals, and one-time investment obviously reduces.
When the average velocity of tested vehicle between any two monitor terminals exceeds the setting speed limit, central server sends instruction to monitor terminal, transfer this vehicle characteristics picture that is stored in monitor terminal, compressed, encrypt, synthetic illegal evidence and being saved in the database.
Each monitor terminal is equipped with instantaneous speed measuring device, is used for the instantaneous velocity of measuring vehicle by the control point.
The present invention is because the mode that adopts fixedly monitor terminal and mobile monitoring terminal to be involutory, and both can increase or reduce the zone distance that need test the speed, the accuracy of raising measurement according to different highway sections; And a section of can choose in the road tests the speed at random, can reduce that the fixedly quantity of monitor terminal being set, and reduces cost of investment.
