At present, the state's coal mine safety production has to increase the degree of importance attached to an unprecedented level, but the production of coal mine safety accidents continue to occur, after the accident and emergency rescue and disaster relief and security of the poor ambulance to a large extent exposed the current monitoring the existence of the system of underground work, such as personnel management difficulties and can not be fully real-time detection of mines and other issues of environmental change. In this paper, to solve the above problems started to introduce a wireless sensor network technology for mine detection system platform design and implementation. The system consists of data acquisition subsystem, data-processing subsystem and the ground to monitor the management subsystem is composed of three parts. Acquisition of mobile data acquisition subsystem sensor data collection terminal, and then the data sent to data processing subsystem, by its completion of the data analysis and processing, the final results sent to the management of Sub-Commission, which completed its monitoring of underground working environment. Wireless sensor network technology for the characteristics of a new technology standard ZigBee technology has been put forward in 2002 and has been continuously updated and improved, and received wide support. ZigBee technology emerging as a close-up, low-complexity, low-power, low data rate, low-cost wireless networking technology, mainly for short distance wireless connection. It has its own protocol standards, in thousands of tiny sensors to achieve communication between the co-ordination, the sensor requires very little energy, a way to relay the data through radio waves from one sensor to another sensor, so its communication efficiency is very high. This article first introduced the development of ZigBee technology, ZigBee technology ZigBee specification and characteristics of the CC2430 chip. The second discusses the use of specific temperature and humidity CC2430 complete measurement system with the gas measurement system design, to discuss the power consumption of wireless network management, wireless network configuration, the use of chip temperature sensors and gas sensors detect the ambient temperature and gas concentration, from node to send data, the main node to receive and upload data to the host computer display, etc.
