In order to improve the working environment of the duty personnel of the pressure fan,improve the monitoring ability of the operation parameters of the pressure fan,and timely deal with the abnormal situation of the pressure fan,combined with the equipment and monitoring system of the mine pressure fan room,an unattended pressure fan system was established.Real-time monitoring and control of the power supply and operation of the pressure fan can be realized by applying PLC(Programmable Logic Controller)and sensors,and environmental monitoring,video and infrared detection systems can be used for monitoring,ensuring that the pressure fan can still run smoothly under unattended conditions.After engineering application,the system ran smoothly and all subsystems were connected normally,which effectively realized the expected goal of remote monitoring and unattended operation of the pressure fan.
