Abstract
For limited application problem of traditional roadheader cooling methods by external cooling water, a design scheme of automatic temperature control system for roadheader was proposed. The system uses air cooler as a mandatory cooling unit and PLC as a control unit, and can make temperatures of roadheader cutting motor and hydraulic system within allowable range through temperature signal acquisition and processing and PID control. Underground industrial test result shows that the system helps roadheader run long and stably without external cooling water.
