Research on a Comprehensive Road Tester using Wireless Data Transmission
In order to measure the acceleration noise effectively and accurately,the instantaneous speed of the motorcycle entering the test road should be accurately measured according to the standard requirements.In this paper,a wireless transmission type comprehensive road tester is designed.According to the time difference of the signal generated between each pressure belt and the distance between the pressure belts,the speed of the vehicle passing through the two pressure belts is calculated,so as to realize the speed measurement of the vehicle.The test data adopts wireless data communication between the measuring end and the receiving end,and the data acquisition port can be expanded according to the different standards and test requirements.It is easy to measure the speed of multiple vehicles and easy to operate.The test data is calculated and wrapped at the measuring end and then transmitted to avoid the data distortion caused by interference and realize the speed measurement of the vehicle.
