Exhaust apparatus 112, is mainly used in reducing the concentration of pernicious gas or fuel gas in installation environment.
When control platform 120 receives a certain pernicious gas of the transmission of monitoring side 110 (such as hydrogen sulfide, carbon monoxide or first
Alkane) after Concentration Testing result, if Concentration Testing result is too high, control platform 120 can be according to the Concentration Testing result and first
The relation of threshold value generates corresponding exhaust instruction, and early warning information.And the row of monitoring side 110 is sent to by communicator 114
Device of air 112, or the processor of monitoring side 110 is sent to, started by processor control exhaust apparatus 112, be exhausted, will
In inspection shaft 211, the concentration of the gas corresponding with Concentration Testing result of (or in other installation environments) is reduced, with around ensureing
Environmental security, prevents the generation of the perils such as blast.The wherein relation of Concentration Testing result and first threshold can be, concentration
When testing result exceedes threshold value, or numerical value that the super brother's threshold value of Concentration Testing result is certain (can according to more than data number
Generate different exhaust instructions) when.
Preferably, the exhaust apparatus 112 can be one (as shown in Figure 1) or multiple scavenger fans or exhaust pump.Meanwhile,
Should be (more closed such as 211 class of inspection shaft with installation environment respectively by the two ends of the scavenger fan fan of connection (or exhaust pump)
Or narrow and small environment) connect with the external world；Extraneous air can be blowed in inspection shaft 211, or by containing in inspection shaft 211
The air of dangerous or fuel gas is extracted out；To reduce the concentration of the dangerous or fuel gas in installation environment.The scavenger fan
Exhaust power also can make corresponding control according to the physical relationship of Concentration Testing result and first threshold by control platform 120.
When the under test gas in environment to be detected reach reasonable concentration or non-hazardous concentration range, control platform 120 can
To produce corresponding control command to stop the work of exhaust apparatus 112.
Liquid level detection device 113, mainly for detection of the liquid level change in monitoring installation environment.When liquid level is more than one
When determining height, corresponding emergency processing can be carried out in advance, prevent water level from exceeding monitoring box 131, flood monitoring side 110
Electronic component etc., non-water-tight equipment.
Preferably, the test side of liquid level detection device 113 should be located at the ground below the horizontal plane that monitoring box 131 is located
