This paper presents the structure and main function of a methanealarm and power-off control device controlled by a single-chip microcomputer
which is first used in China.This paper mainly discusses the circuitry and work-ing principle of a computer and how to solve some special problems when the single chip microcomputer is used in a coal mine where methane exists.
