This paper topic originates from mine emergency multimedia communication system research and development duty. This paper mainly studied how to gathering, displaying, storing and transmitting the mine environment parameter and reporting the alarm effectively. The mine environment parameter detecting equipment will apply to the mine emergency rescue. This technical result can apply to other environment examination domains, too. Firstly, on the basis of analyzing the requirement of mine environment parameter detection, the author chose methane, carbon monoxide, oxygen and temperature as the environment parameter. After studying the principle and method of mine gases and temperature parameter gathering, the author chose an appropriate gas gathering method and established the system design plan. The system design based on the intelligent gas sensor, the temperature sensor and the C8051F330 integrated circuit. The design plan realizes following functions: gathering, displaying, storing, transmitting environment parameter; power source instruction; power owes voltage instruction; the intelligence turn on/off operation; the intelligent soft close-down operation and pause operation. Secondly, the paper describes the hardware realization and the software debugging. The hardware part consists of MCU-C8051F330 module; the intelligent gases gathering unit; temperature sensor; the intrinsical security power source module and network switchboard. For the purpose of software maintenance and development, the software adopted the modular design method. The software part mainly includes: Firmware program module, environment parameter gathering module, network connection module. Finally, in order to ensuring the system work stability and the communication security, the author has carried on the detailed debugging to the system software and hardware. The test result shows that its function and performance meet the requirement of the mine environment parameter examination. Its application will sharpen the mine rescue ability and the efficiency.
