The invention relates to the field of vehicle speed real-time monitoring, in particular to a vehicle real-time running speed measuring system and measuring method, and solves the problem that a conventional speed measuring module cannot measure the vehicle real-time running speed and image capture is affected when a road vehicle border defense safety detection system takes pictures. The system comprises a microprocessor, distance measuring sensors, a camera module, a geomagnetic detector, a display module, a road surface center line and a road surface calibration line; when a vehicle passes through the geomagnetic detector, the microprocessor detects incoming vehicle signals, the system enters a working state, the vehicle advances according to the road surface center line, and the microprocessor controls the left and right distance measuring sensors to work at the same time; the microprocessor calculates according to the distance data measured by the left and right groups of distance measuring sensors and the data receiving time of the sensors to finally obtain the real-time running speed of the vehicle, and the real-time vehicle speed is displayed on the display module; the microprocessor and the camera module shoot and store the vehicle and the road surface calibration line in real time through communication data transmission.
本发明涉及车速实时监测领域,具体涉及一种车辆实时行驶速度的测量系统及测量方法,本发明了解决公路车辆边防安全检测系统拍照时,常规的测速模块达不到车辆实时行驶速度的测量,进而影响拍照的问题,包括微处理器、测距传感器、摄像模块、地磁检测器、显示模块、路面中心线和路面标定线,当车辆通过地磁检测器时,微处理器检测来车信号,系统进入工作状态,车辆按照路面中心线行进,微处理器控制左右两组测距传感器同时工作,微处理器根据左右两组测距传感器测量的距离数据与传感器接收数据的时间进行计算,最后得出车辆实时行驶速度,显示模块上显示出实时车速;微处理器和摄像模块通过通信数据传输,实时将车辆与路面标定线拍摄保存。
