China is a major coal-producing country , but it is also a mine disaster occurred more and more countries . After years of research found that the gas is caused by mine explosions and mine collapse , triggering one of the main mine . In addition to gas , the concentration of carbon monoxide , temperature and humidity and other factors also largely affect the production of the mine . Therefore, only monitoring the concentration of gas in the mine , the concentration of carbon monoxide , as well as temperature, humidity and other environmental information in a timely manner in order to ensure the safety of the mine working environment . The other hand, most of the current mine safety monitoring system wired signal transmission , wiring trouble in this way , the high cost of the line depends on the degree is also very strong , installation and maintenance . When the mine , equipment and wiring tends to be a certain degree of damage , can not provide reliable help for rescue work in the mine . This paper describes the status of the coal mine gas accidents occur frequently , the temperature of the coal mine , the concentration of methane gas , carbon monoxide gas concentration monitoring the latest short -range wireless network and sensor system design, node - based hardware and software design and implementation, as well as through SMS cat hardware to send alert information design . Hardware design collection terminal node design, including a gas sensor application circuit design, circuit design of temperature sensor applications , carbon monoxide sensor application circuit design . Software design, including the acquisition of temperature, concentration of methane gas , carbon monoxide gas concentration , networking and communications between nodes . In addition, the use of the latest short range wireless sensor development system , to achieve a short-range wireless communications network based on the IEEE802.15.4 protocol and ZigBee standard design , and experiments were carried out on the actual composition of the short-range wireless sensor networks and data analysis. The design of short-range wireless sensor networks in coal mine production safety exploratory attempt experimental program initially realized the coal mine temperature and other environmental information collection and transmission . For coal mine safety monitoring technology development and application , with the a certain application reference value .
