Design of automation and remote of mine local ventilator
In order to solve the problem that when the local fan power is cut off,the gas can be automatically discharged when the power is called again,and the main backup of the local fan can be switched on by itself after the failure,so as to realize automation,and remote monitoring and centralized control of mine local ventilator to achieve remote.The paper designs the circuit diagram of automatic control of mine local ventilator based on Simatic S7-200 Smart Plc,compiles the automatic control program of mine local ventilator with STEP 7-Micro WIN SMART software,realizes the communication of comprehensive protection between PLC and mine local ventilator with Modbus communication protocol,and uses kingview 6.55 to build the background monitor.The correctness of the control system is verified by the program simulation,the construction of the control system and the field test.The realization of the automation and remote control of the local fan in the mine is beneficial to reducing the number of people and improving the efficiency,improving the Factor of safety of the staff and reducing the unnecessary injury and economic loss.
