[0042] The third embodiment
[0043] A self-diagnostic method of carbon monoxide sensor for coal mines is: to diagnose circuit faults, first determine the signal output type, when PORT_CTRL1 is high (H) voltage, PORT_CTRL2 is low (L) voltage, and PORT_CTRL3 is low (L) voltage When PORT_CTRL1 is low (L) voltage, PORT_CTRL2 is low (L) voltage, and PORT_CTRL3 is low (L) voltage, it is frequency output; when PORT_CTRL1 is any (X) voltage, PORT_CTRL2 is high (H) Voltage, when PORT_CTRL3 is high (H) voltage, it is RS485 bus type output; when the signal output type is current type output, the current type open circuit LED indicator light is open, and the current type open circuit LED indicator light is off as no open circuit. When the current type short circuit LED indicator lights up as a short circuit, the current type short circuit LED indicator lights off as no short circuit; when the signal output type is frequency type output, the frequency type open circuit LED indicator lights...
