Described acousto-optic warning unit is by bus driver.
Described detection of gas unit has LED or LCD concentration Presentation Function.
Described gas alarm control module can to the function sent instructions under probe unit.
Described high-power double bus detection of gas alarm control system adopts the communication mode of active reporting.
The beneficial effects of the utility model:
Achieve the double bus connected mode that detection of gas unit and gas alarm control unit transmission signal line and power supply line share, gas alarm control module can send instructions under detection of gas unit, when there being Leakage Gas, detection of gas unit initiatively can send instruction by bus, warning message is transferred to alarm control unit, drive the audible-visual annunciator being less than 2W simultaneously, alarm control unit is according to gas concentration information, link corresponding air draft, the devices such as spray, this enforcement reduces winding displacement cost to a certain extent, shorten the passing time of failure message.
