Coal Mine Gas Inspecting System Based on Data Fusion of Multi-Sensor

Abstract

This paper illustrates a low energy consumption and high accuracy WS N (wireless sensor network) that provides an intelligent gas inspecting system in coal mines, which offsets the shortage of mine cable monitoring system.The substation of coal mine gas inspecting system was designed by CC2530 SOC that is responsive for data acquisition and transmission, which integrates sensor technology, wireless communication technology and data fusion technology.The overall framework of the system was given, and the WS N was designed in detail, including gas sensor, inspecting substation.The system offers the real -time data transmission between underground mine and surface monitoring centre through highly secure, reliable wireless sensor network, which improves the mine's safety.
