The monitoring scope includes but is not limited to parameters such as images, temperature, sound, etc. The vehicle status monitoring system is an essential device for vehicle electromagnetic compatibility tests. Since the vehicle runs at high speed on the drum and the body jitters greatly, the fixing scheme of the monitoring system is an important part of the test.
