The invention relates to a gas detection and ventilation equipment linkage control method,
system, equipment and medium, and the method comprises the steps: monitoring the
gas concentration of a target area in real time through a
gas detector, and generating a linkage instruction
signal containing a self address identifier when the
gas concentration reaches a preset alarm threshold value; the gas detectors directly send the linkage instruction signals to at least one set of specified ventilation equipment through a shared communication
bus, and the shared communication
bus is the same physical
communication link for connecting the plurality of gas detectors, the at least one set of ventilation equipment and a gas alarm controller; and the specified ventilation equipment executes corresponding start-stop or speed regulation operation based on the received linkage instruction
signal so as to solve the problems of
response delay, single-point failure, single control strategy and the like of the existing centralized linkage
system, thereby achieving the purpose of quicker, more reliable and more refined safety linkage control.
