Coal mine ventilator wireless monitoring system based on Zigbee technology

The utility model discloses a coal mine ventilator wireless monitoring system based on a Zigbee technology. The coal mine ventilator wireless monitoring system is characterized by being composed of an upper computer main station and a sensor substation. The upper computer main station is mainly composed of an upper computer and a gateway node, and the gateway node is mainly composed of a CC2530 minimum system, a power module, a level transformation module and a display circuit. The sensor substation is mainly composed of a CC2530 minimum system, a power module, a display circuit, a voltage transformer, a current transformer, a temperature and humidity sensor, a gas sensor and a gas pressure sensor. The upper computer main station and the sensor substation are in wireless communication through the Zigbee technology, and relevant data collected by the sensor substation are sent to the upper computer main station for monitoring. The coal mine ventilator wireless monitoring system is used for monitoring a coal mine ventilator, and compared with a traditional ventilator monitoring system, the cost of the monitoring system is lowered, the complexity degree in the system mounting process is relieved, and the failure rate in the system using process is lowered.
