Other AbstractThe invention relates to a bus-type flammable gas concentration detection device and a control method thereof. The device comprises a gas concentration detection portion connected with the detection input terminal of a control portion the control portion including a microprocessor loaded with a control program for receiving a detection signal from the gas concentration detection portion and outputting to a display portion and an alarm portion the display portion connected with the display output terminal of the control portion the operation portion connected with the operation input terminal of the control portion an alarm output portion with a sound alarm device coupled with the alarm output terminal of the microprocessor through a photoelectric coupler and a bus interface portion with a bus communication module for emitting information of the microprocessor in the control portion to a bus. The method comprises the steps of initializing the device, detecting the concentration of a flammable gas, and serially communicating with an upper controller at any time. The invention achieves network concentration detection of flammable gas, high measurement accuracy, high explosion-proof performance and large amount of display information.
