为改善液压牵引采煤机司机的工作条件,采用PLC做为控制主机,加装液压控制装置及无线收发装置,对采煤机实现无线遥控、网络控制,并进行过载、过流及断相保护,及恒功率自动控制等功能。改变了传统液压牵引采煤机的操控方式,提高了采煤机的操作及控制的安全性。
In order to improve the working conditions of hydraulic traction shearer drivers, the PLC is used as the main control unit, hydraulic control device and wireless transceiver are added to realize wireless remote control and network control of shearer, overload, overcurrent and phase failure protection , And constant power automatic control and other functions. Change the control method of the traditional hydraulic traction shearer and improve the operation and control safety of shearer.
