Abstract:

According to the practical coal mine safety production, the paper introduces the overall framework of the coal mine gas detection alarm instrument basing on single chip microcomputer (SCM). Then the paper introduces the detailed design for each part of the hardware of the coal mine gas detection alarm. The paper proposes the design block diagram of hardware circuit and the design block diagram of software program. Finally the paper verifies the correctness and feasibility of the design and content by using proteus software. The simulation proofs that the coal mine gas detection alarm instrument basing on single chip microcomputer (SCM) has application value on the monitor and control system in coal mine safety production.

Key words: Coal Mine Safety Production, Gas Concentration Detection Alarm Device, Single Chip Microcomputer System, Computer Simulation, Proteus.
