Ultrasonic pulse Distance-Measurement installed on both sides of the truck can monitor the status inside the truck, so the system could show the real-time measured distance and warn when dangerous, that effectively prevents the occurrence of collision accidents. And the system can also transfer the data to the host machine through the CAN bus. Therefore, the network control and remote monitoring are realized.
