Abstract
A method for linkage between an alarm based on gas and a gas meter is provided. The method is executed by the gas meter. The method includes: obtaining a detection signal through electrical connection with the alarm; determining a target alarm event corresponding to the detection signal in response to the detection signal meeting a preset alarm condition; in response to the detection signal meeting the preset alarm condition, receiving a reset instruction issued by a management platform; performing reset operation on the alarm based on the reset instruction; obtaining a reset detection signal and determining a reset alarm event corresponding to the reset detection signal; determining a credibility of the target alarm event; sending a control closing instruction to the gas meter based on the credibility larger than a preset credibility threshold, and closing a gas valve of the gas meter based on the control closing instruction.
