Abstract

In order to improve the stability of the hydraulic control system for coal mining equipment, PWM technology is used to accurately control the hydraulic proportional valve group. A communication system is established through CAN communication, and PWM signals are used to directly drive and control the proportional solenoid valve. The control accuracy of the electro-hydraulic proportional valve is ensured by feedback on the output current of the controller. The characteristic curve and time response of the valve are parameterized and programmed to improve system performance, Improved system quality and load application scenarios. The actual operation results show that the performance of the mining equipment walking electro-hydraulic control system is stable and reliable, which improves the safety, reliability, and sensitivity of the equipment walking electro-hydraulic control. This lays a solid foundation for achieving unmanned operation of mining equipment and building green mines.
