Abstract
A method for linkage alarm between a gas alarm and a gas meter is provided. The method comprises: obtaining a detection signal through electrical connection with the alarm; in response to the detection signal meeting a preset alarm condition, determining a target alarm event corresponding to the detection signal; when the target alarm event is the abnormal gas concentration in the target area, closing, by the gas meter, a gas valve of the gas meter; when the target alarm event is the abnormal operation of the alarm or the abnormal connection of the alarm, receiving a reset instruction; determining a reset alarm event corresponding to the at least one reset operation; determining a credibility of the target alarm event; determining whether to send a control closing instruction to the gas meter based on the credibility; and closing the gas valve of the gas meter based on the control closing instruction.
