    Build the control system and monitoring system in the control console. The operator can remotely control the travel and movement of the scraper through the operating mechanism such as the handle on the console. The operator performs the necessary operations on the knobs, buttons, and handles on the console, and the operation is compiled and sent to the controller. And then through the wireless network on the scraper start, speed, steering, throttle and brake to remote control, make it moving in required speed and required way, so as to realize remote control and monitoring of the scraper. At the same time, scraper transfer the real-time image and operating parameters of video signals of the road condition in the front and back of scraper through the wireless network real-time transmission to the PC installed on the console display, so that the operator are able to remotely control the scraper’s real driving environment, thus monitoring the operation condition of scraper. The scraper, the human (remote driver), and the remote control console (remote control platform, wireless router, camera, control system, etc.) form a closed-loop control system.
