Coal mine closed area monitoring system based on wireless network and communication method

The invention relates to the technical field of mining safety monitoring, in particular to a coal mine closed area monitoring system based on a wireless network and a communication method. The system is composed of a ground main station, an underground base station and a wireless sensor. The ground master station communicates with the underground base station in real time, and analyzes and processes data monitored by an underground closed area; the underground base station is a core control part of the whole system and is used for automatically timing or manually acquiring sensor data and uploading the sensor data; the wireless sensor is bottom equipment, is powered by a battery, has the functions of data acquisition, networking communication and the like, and comprises various gas sensors, temperature sensors and environment pressure sensors. The system is highly intelligent, can timely and accurately monitor the environmental data of the closed area of the coal mine goaf, and provides technical guarantee fo
