Intelligent Unmanned Control System for Local Ventilation Fan in Coal Mine

The local ventilation fan in the mine undertakes the task of ventilation underground and is an important electrical and mechanical equipment for ensuring safe production in the mine. It needs to maintain long-term, continuous, safe, and reliable operation. This paper mainly designs an intelligent monitoring system for the local ventilation fan in the mine based on Siemens S7-1200 PLC

. The functions, hardware circuits, and software programs of the system are designed. The human-machine interface is used to monitor the local ventilation system of the mine in real-time, allowing for visual observation of the operation of the local ventilation fan in the coal mine. Based on the detection and warning functions of the system, timely adjustments can be made to the ventilation system, greatly improving the safety of the local ventilation system in the coal mine. It also enhances the level of intelligent management of the local ventilation fan equipment, which is beneficial for improving the economic efficiency of the enterprise.
