The gas leakage alarm system further comprises a second gas data acquisition module 103, wherein the second gas data acquisition module 103 is arranged in the household gas pipeline and used for acquiring gas flow data in the household pipeline. In a specific example, the second gas data acquisition module 103 may be arranged at a front end of the gas-fired metering appliance, for example. The gas leakage alarm system further comprises a gas leakage alarm module 101, and the gas leakage alarm module 101 is in communication connection with the first gas data acquisition module 102 and the second gas data acquisition module 103 to acquire gas use data and gas flow data.

In a specific example, the first gas data acquisition module 102 may include a temperature sensor to measure the temperature or heat generation of the gas using terminal equipment, and the second gas data acquisition module 103 may include a gas flow sensor to sense whether gas flows in the service pipes. For example, when the second gas data acquisition module 103 senses that gas flows in the household pipeline, and the first gas data acquisition module 102 senses that the temperature of the gas using terminal device is lower than a certain threshold or no heat is generated, it is determined that gas leakage exists. In this case, the gas leakage alarm module 101 performs a gas leakage alarm (e.g., an acoustic, optical alarm, etc.) and timely informs a user or a gas company, a community center, etc.
In order to avoid the safety problem caused by gas leakage in time, the second gas data module 103 may further include an electric control valve, and when the gas leakage alarm module 101 determines that gas leakage occurs, the gas service pipeline is cut off in time by sending a valve closing instruction to the electric control valve.

Therefore, in order to more accurately determine the location of the gas leakage and to cope with the gas leakage situation, the first gas data acquisition module 102 may further include a gas flow sensor to sense the gas flow situation in the gas usage terminal device.
In this case, the first gas data acquisition module 102 further acquires gas flow data of the gas usage terminal device in addition to acquiring temperature or heat data of the gas usage terminal device.
The gas leakage alarm module 102 determines whether gas leakage occurs based on temperature or heat data of the gas using terminal device, gas flow data, and gas flow data in the household pipe.

S3: the gas leakage alarm module 101 judges whether gas flows in the gas household pipeline or not based on the gas flow data D2, if so, the step goes to step S5, otherwise, the step goes to step S4.
S4: the timer starts counting time and judges whether the timer value is greater than a predetermined time value, if so, proceeds to step S2, otherwise, continues to step S4. The predetermined time value may be set to, for example, 3 minutes, 5 minutes, or the like, and by setting the predetermined time value, regular inspection of the gas leakage situation is realized.
S5: the gas leakage alarm module 101 judges whether gas flows in the gas using terminal equipment based on the gas using data D1, and if so, proceeds to step S7, otherwise, proceeds to step S6.
S6: the gas leakage alarm module 101 determines that the indoor gas conveying pipeline is leaked, and gives an alarm for the leakage of the gas conveying pipeline.
S7: the gas leakage alarm module 101 further determines whether heat is generated in the gas usage terminal device based on the gas usage data D1 (for example, when the sensed temperature is greater than a predetermined threshold, it is determined that heat is generated, which indicates that the gas usage terminal device is in a normal usage state), and if so, proceeds to step S4, otherwise, proceeds to step S8.
S8: the gas leakage alarm module 101 determines that leakage occurs at the gas using terminal device and gives an alarm of the gas using terminal device leakage.
