The vehicle-mounted equipment usually includes video recorders, station announcers, cameras, GPS antennas, GPRS antennas, SIM cards, etc. When the vehicle-mounted equipment fails, technicians usually need to get on the vehicle for maintenance. During the maintenance period, the vehicle cannot drive normally. After the on-board maintenance, the detection instruments are generally placed on the vehicle. When the engine needs to be started for maintenance or testing, the vehicle will vibrate, and there are many sensors in the vehicle-mounted detection instruments. The vibration will have a certain impact on the sensitivity and stability of the sensors. After frequent vibration, the sensors will be at risk of falling off or being damaged.
