Implementation of Monitoring and Control System of Coal Mine Main Ventilator

Taking monitoring and control of a coal mine main ventilator as an example, the paper put forward a design scheme of monitoring and control system of main ventilator based on PLC, power monitor and configuration software, and introduced hardware configuration, implementation scheme and main functions of the system. The system realizes monitoring and control fuction of each link of coal mine main ventilator. The practical application showed that the control system is reliable, easy in control and strong in extend.
