Abstract

Aiming at the safety risks of close-range operation within the safety clearance, traveling operation and harsh working conditions of the outboard control console of conventional large track maintenance machinery, a non-contact control system based on STM32 is designed. The system combines photoelectric switches with ultrasonic ranging technology to realize start-stop, reversing and stepless speed regulation of working mechanisms by identifying hand gestures. LoRa wireless networking is adopted to complete data exchange within a formation, and remote condition monitoring and intelligent operation and maintenance of the equipment are realized. A hardware-level traveling interlock logic is built in, which directly cuts off traveling power of the vehicle when the working mechanisms are not fully retracted, thus establishing a safety interlock mechanism at the hardware level. Test results show that the system effectively isolates personnel from hazardous areas and significantly improves the operational safety margin and intelligent level of large track maintenance machinery.
