The research of intelligent gas observation system based on ARM

Aiming at the practical situations of frequent gas accidents on mine and existing mine wire communication system urgent needs to be improved toward wireless communication system, this paper introduces thedesign of gas monitoring system based on ARM. It consists of a intelligent analysis device and several gas density data acquisition units. The wireless communication between intelligent analysis device and gas density data acquisition units is achieved by radio frequency chip. The paper introduces the principle and design method of whole monitoring system in details, makes analysis of essential circuits, and presents the hardware and software designs of essential circuits.
