[Abstract]:Mine ventilation is an important link in the process of metal mine production and is an important measure to realize safe production and prevent hidden danger of safety. Effective and reasonable ventilation can not only meet the ventilation requirements of mine production, but also play a vital role in creating a good working environment and controlling fire. In order to solve the problem of underground mine ventilation safety better, this paper proposes a mine ventilation monitoring system based on WiFi communication technology, which includes the following aspects: (1) comparing and analyzing various wireless communication technologies, The feasibility of mine ventilation monitoring system based on WiFi is determined in combination with underground practical application. (2) the wireless sensor, network architecture and wireless sensor network are analyzed, and according to the requirements of ventilation monitoring system, The application environment of each sensor (temperature sensor, humidity sensor, gas concentration sensor and air volume intelligent sensor) is determined; (3) underground ventilation environment monitoring. Through the intelligent sensor to complete the field data collection, through the temperature sensor, humidity sensor, dust concentration sensor and air volume intelligent sensor, the dust concentration in the production face and roadway, underground temperature, etc. Real-time monitoring of humidity and air volume; (4) downhole data transmission. Through WiFi communication technology to send different addresses to control the intelligent sensors to carry out the measurement work in turn, and read and store the measurement data, and centralize, analyze and process the measured data, judge and alarm, and form various statistical reports. Curve or computer documentation; (5) Fan control. Single-chip microcomputer is used to control the operation of fan. The problems that may occur in the operation of the fan are set up, and the corresponding treatment methods are made for different problems, and the automatic control of the fan is accomplished by using a single chip microcomputer. This system optimizes the traditional mine ventilation monitoring system, integrates WiFi technology, wireless sensor technology, single chip computer technology and computer network technology, and designs the ventilation monitoring system according to the actual situation of Jinshankou Copper Mine. The underground ventilation data are automatically recorded, stored and processed in real time and automatically. The automatic, intelligent, hierarchical and networked mine ventilation monitoring is realized.
