The high-speed laser rangefinder can measure the speed of the vehicle

Vehicle height measuring equipment on the expressway is usually installed at the toll station, because the vehicle residence time of the toll station is short, and the vehicle height measuring instrument used at the toll station is usually a low interest rate laser rangefinder. The height of some vehicles entering and leaving the station is in line with the standard, but some drivers will do some speculative activities on the highway to increase the hidden dangers of traffic accidents. Recently, in some places, three big trucks have been found to be dangerous. In order to save gasoline, the driver of a large truck was driven by two other overlapping trucks on the highway, which made other drivers feel scared. In order to prevent this from happening, the Transportation Department decided to install a height measurement system in sections on the expressway. The ordinary laser rangefinder cannot complete the task of height measurement due to the high-speed driving of cars on the expressway. Lin Yangzhi can use high frequency laser rangefinder to solve the problem of expressway height measurement. The frequency of high frequency laser rangefinder is 100? 2000Hz According to the speed of the scene, Lin Yangzhi can choose a 200Hz laser rangefinder. The 200Hz frequency is a laser that can continuously measure and emit 200 data in 1 second. The data processor can even measure its height on a 200 m/s highway.
