Application of Integrate Sensor in Gas Alert System of Coal Mine

摘要

Authors have fulfilled the design of application of integrate sensor in gas alert system of coal mine with MSP430. A real inspection and measurement system of helmet has been designed in order to solve the safety problem of miner in mine with the foul environment. The alert system can send out the alert signal by self-motion when the gas thickness valve is over the alert one by the way of real inspecting, measuring, gathering and dealing with MSP in order that miner can be out of danger in time. Each miner has an alert helmet with location identity function because of the micromation and inexpensiveness of it.
