1. A method for linkage between an alarm based on gas and a gas meter, wherein the method is executed by the gas meter, comprising:
obtaining a detection signal through electrical connection with the alarm; and
in response to the detection signal meeting a preset alarm condition, determining a target alarm event corresponding to the detection signal, and uploading the target alarm event to a management platform through a sensor network platform, wherein the target alarm event includes at least one of an abnormal operation of the alarm, an abnormal gas concentration in a target area, and an abnormal connection of the alarm,
when the target alarm event is the abnormal operation of the alarm or the abnormal connection of the alarm,
in response to the detection signal meeting the preset alarm condition, receiving a reset instruction issued by the management platform, wherein the reset instruction includes a reset time period, a reset object, and a reset count, and the reset object includes at least the alarm;
for each reset operation within the reset time period,
obtaining a reset detection signal through an electrical connection with a reset alarm;
in response to the reset detection signal meeting the preset alarm condition, uploading a reset alarm event corresponding to the reset detection signal to the management platform through the sensor network platform, wherein the management platform is configured to:
determine credibility of the target alarm event based on the reset count, a type and number of reset alarm events received within the reset time period, information of the alarm, information of the gas meter, historical alarm information, and environmental information; and
when the credibility is greater than a preset credibility threshold, send a control closing instruction to the gas meter; and
when obtaining the control closing instruction issued by the management platform, closing the gas valve of the gas meter based on the control closing instruction.
