Research and Realization of Switchover Control Without Off-Blast of Mine Main Fan
In order to solve the problems of the traditional mine ventilation system"stop and switch"mode,such as large fan starting wind resistance,large air volume fluctuation and gas accumulation caused by the shutdown switching process,this paper proposes a control strategy of non-stop switching of mine main fan based on fuzzy PID control,and uses PLC as the control core and industrial Ethernet as the communication network to design the control system.The remote intelligent control of the opening and closing angle of the vertical and horizontal throttle keeps the air volume constant during the fan switching process and effectively improves the stability of the fan switching process.
