Design of Remote Control System for Car Dumper Based on Wireless Communication

In order to solve the problems of cable wear, high maintenance costs, and complex wiring in traditional wired control systems for dump trucks, a remote control system for dump trucks based on wireless communication is proposed. The system adopts a 2.4 GHz ISM frequency band wireless link, constructs a master-slave distributed control architecture, achieves precise positioning of the carriage through laser radar, implements multi-mode operation control based on finite state machine, and uses CRC-16 verification and redundant link switching to ensure communication reliability. Practical application has shown that the average response time of the system is 187 ms, the communication success rate is 99.7%, the number of system failures is reduced by 71.4%, and the maintenance time is reduced by 57.3%. This proves that the system can effectively improve the efficiency and reliability of the dump truck operation.
