System and method for linkage alarm between gas alarm and gas meter

A system for linkage alarm and controlling between an alarm and a gas meter, comprising a management platform and an object platform, wherein

• the management platform is configured to receive and store a target alarm event sent by the object platform, and perform unified integration, analysis, and management of data,
• the object platform includes the gas meter and the alarm, and the object platform is configured to receive instructions from the management platform, run the instructions, and send perception information to the management platform, wherein
• the gas meter is configured to obtain a detection signal through electrical connection with the alarm;
• in response to the detection signal meeting a preset alarm condition, the gas meter is configured to determine a target alarm event corresponding to the detection signal, and upload the target alarm event to the management 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;
• wherein the preset alarm condition includes that a detection signal level is greater than a second threshold;
• and the gas meter is further configured to:
• when a second channel of the alarm is connected, obtain the detection signal transmitted through the second channel based on the electrical connection with the alarm, wherein when the alarm detects that a gas concentration in the target area is greater than a preset concentration threshold, the alarm controls the second channel to be connected;
• and
• in response to the detection signal level being greater than the second threshold, determine the target alarm event corresponding to the detection signal being the abnormal gas concentration in the target area;
• when the target alarm event is the abnormal gas concentration in the target area, the gas meter is configured to close 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,
• the gas meter is configured to receive a reset instruction issued by the management platform, wherein the reset instruction is used to perform at least one reset operation on a reset object, wherein the reset object include at least the alarm;
• the gas meter is configured to determine a reset alarm event corresponding to the at least one reset operation, and upload the reset alarm event to the management platform;
• the management platform is configured to determine a credibility of the target alarm event based on the reset alarm event;
• the management platform is configured to determine whether to send a control closing instruction to the gas meter based on the credibility of the target alarm event;
• and
• the gas meter is configured to close the gas valve of the gas meter based on the control closing instruction issued by the management platform.
