Abstract

The invention relates to a coal-mine gas monitoring system comprising a wireless sensor network, which belongs to coal-mine safety monitoring techniques. The system comprises a ground monitoring center and a wireless sensor network. The ground monitoring center comprises a monitoring centre client, a monitoring centre server and a common client; wherein the monitoring centre server is connected with both the monitoring centre client and the common client. The wireless sensor network comprises sensor network nodes, a network cluster head, and a wireless transceiver. The sensor network node comprises a processor module, a wireless communication module, a data acquisition module, an energy supply module, and an intelligent switch; wherein the wireless communication module, the data acquisition module and the intelligent switch are both connected with the processor module. The intelligent switch is connected in the circuit of the data acquisition module to control the power on / off thereof. The network cluster head receives the data sent from the sensor network nodes and communicates with the wireless transceiver. The system can real-time effective transmit data to monitor coal-mine gas, so as to reduce accidents and ensure coal-mine safety.

Description

(1) Technical field [0001] The invention relates to a wireless sensor network coal mine gas monitoring system based on ZigBee technology, which belongs to the technical field of coal mine safety monitoring. (2) Background technology [0002] The coal mining industry is also known as a high-risk industry. At present, gas explosions in coal mines are one of the important reasons for underground accidents in my country. The existing traditional gas detection technology has many limitations, such as the system cannot know the gas concentration at multiple locations in the well, the real-time performance is not high, and remote monitoring is not possible. In the traditional coal mine gas monitoring system, because the facilities and devices of the monitoring system are relatively fixed, the gas probe cannot be followed up with the progress of mining, so the monitoring system is often useless, and the underground network is difficult. Relevant personnel cannot carry out effective...
