Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
As shown in Figure 1, a kind of gas-monitoring equipment, including stacked switch 1, immunity module 2, probe single-chip microcontroller 3, gas
The 4, first relay 5 of probe and the second relay 6.
The stacked switch 1 includes DC power supply 101, the output end of the DC power supply 101 respectively with coalcutter 7, anti-
The electrical connection of the input terminal of interference module 2 and the first relay 5, the output end of the immunity module 2 and single-chip microcontroller 3 of popping one's head in
The output end of input terminal electrical connection, the probe single-chip microcontroller 3 is electric with the input terminal of gas probe 4 and the first relay 5 respectively
