The invention discloses an intelligent monitoring system for a coal mine local ventilator, and relates to the technical field of ventilators. The system comprises a ground dispatching room, an underground monitoring substation, a control cabinet, a local ventilator and a sensor, the sensor is used for detecting the state of the local ventilator and underground environment information, and the detected information is transmitted to the ground dispatching room and the underground monitoring substation through a communication network; and the state of the local fan, the electrical parameters of the control cabinet and the underground environment information are displayed on a monitoring interface in real time, and the operation parameters of the fan are adjusted in real time according to the monitoring information, so that the underground ventilation safety is ensured. The system has the functions of remote monitoring, real-time early warning, man-machine double control, on-demand air supply and disaster prevention and reduction, the problem that the ventilator is manually controlled and maintained for a long time is solved, real-time remote monitoring of the ventilator is achieved, and mine safety is improved.
Description
technical field [0001] The invention relates to the technical field of ventilators, in particular to an intelligent monitoring system for local ventilators in coal mines. Background technique [0002] Under the background of the era of intelligence, the coal mining industry is developing in a safe, green and efficient direction with few people and no one. Among them, the proposal of smart mine construction has accelerated the transformation of the coal mining industry. The intelligent monitoring of local ventilators has been highly valued by the industry. At present, local ventilators are still mainly controlled manually, and there is a problem of "one wind blowing", resulting in waste of resources. Monitoring of local ventilators and underground environment is limited to simple methods such as video monitoring, and internal problems cannot be detected in time. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent monitoring ...
