基于PLC的液压牵引采煤机的无线控制系统研究

Experience Analysis of Wireless Control of Hydraulic Traction Shearer Based on PLC

针对MGD150-NW型采煤机在运行中存在其电控系统保护功能弱、对其滚筒高度的调整只能凭借经验等问题,提出对该种型号的采煤机液压控制系统的改造方案,即在采煤机液压系统上增设一个无线遥控装置。该装置是运用编码和解码的技术对采煤机进行遥控的,可有效解决上述问题。

In view of the problem that MGD150-NW shearer has weak protection function of electric control system in operation, and the adjustment of drum height can only rely on experience, this paper puts forward the retrofit scheme of hydraulic control system for this type of shearer. That is to add a wireless remote control device on the hydraulic system of shearer. The device uses coding and decoding technology to remote control the shearer, which can effectively solve the above problems.
