Design of Gas Density Monitor System Based on Wireless Sensor Network

Abstract

Aimed at the presented serious problem of mine collapse , a monitoring system for coal mine safety based on wireless sensor network is designed. The system overtakes the limitation of traditional system that the situation in mine is unknown in time. With this system, the security manager can real-time monitor the gas density of multi-location .Compared with traditional system, this system is portable and extensible and it also has advantage of physical size and power consumption. This paper describes both the whole system architecture and the structure of single node, furthermore, it also introduces the application method.
