【Abstract】 The paper introduced a new developed long distance control system for ventilation door in underground mine. The system can control the open/close operation of the ventilation door with the telephone network to transfer the control signals. With the existing telephone line for the communication, no special communication cable should be placed and great of money and material can be saved. The ventilation controller is developed with a processor. The controller can analyze and judge the long distance instructions with a high anti interference capacity and a full safe reliability. The system is consisted of a surface computer, a ventilation door controller, a electric motor driven door and a telephone network. The paper introduced the design and development of the software and hardware for the above each part and the system application in Chaili Mine of Zaozhuang Mining Group Corp.更多还原
