Abstract： |
The invention relates to a traffic video checking technique, which is characterized in that: the invention uses several converters to control several convert motors, to drive the vehicle modes arranged on each synchronous transmission band controlled by convert motor to move in uniform speed, (while the speed is adjustable); and each converter is controlled by one computer, to simulate the traffic flow of multi channels; the invention also uses one multi-path light source controller controlled by computer to generate the projections of vehicle modes on different directions, to improve the check complexity. The invention can simulate the checking condition of multi vehicle channels, while the control accuracy of traffic flow is less than +-4%, to be used as mark in traffic flow checker. |
