Abstract
Aiming at the problems that alarming signal of gas alarming head lamp at present can′t be obtained by monitoring center and fixed gas detector has small monitoring areas and is difficult to move,the paper proposed a design scheme of multi-function gas alarming head lamp with the function of wireless transmission of gas overrun signal. It introduced design of hardware and software of the head lamp in details, as well as gave wireless communication scheme and several key technologies.The field experiment showed that wireless communication distance of the head lamp could reach 160 m in coal mine underground, which made up shortage of fixed point gas monitoring,and ensured safe production of coal mine.
