The gas usage monitoring system further comprises a second gas data acquisition module 103, the second gas data acquisition module 103 being arranged in the gas service conduit, in particular at the front end of the gas meter 104, for acquiring gas flow data in the service conduit. The gas usage monitoring system further comprises a gas leakage and gas theft alarm module 101, and the gas leakage and gas theft alarm module 101 is in communication connection with the gas metering instrument 104, the first gas data acquisition module 102 and the second gas data acquisition module 103 so as to acquire a gas usage value, gas usage data and gas flow data of a corresponding gas user. The gas leakage and gas stealing alarm module judges whether gas leakage or gas stealing occurs or not based on the gas consumption value, the gas use data and the gas flow data, and performs gas leakage or gas stealing alarm when the gas leakage or gas stealing occurs.
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 device, so as to determine whether the gas using terminal device is in use according to the temperature. The second gas data acquisition module 103 may include a gas flow sensor to sense whether gas is flowing in the service conduit. 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 and theft alarm module 101 performs gas leakage alarm and timely informs a user or a gas company, a community center, etc.
In another specific example, when it is sensed, for example, by the first gas data acquisition module 102, that the temperature of the gas-using terminal device is higher than a certain threshold value (i.e., the gas-using terminal device is in use), and the gas usage value obtained by the gas meter 104 is not changed, it is determined that gas theft or gas theft exists. In this case, the gas leakage and theft alarm module 101 performs a gas theft alarm, and timely informs a gas company and the like.
In order to avoid safety problems caused by gas leakage and economic losses caused by gas theft for gas companies in time, the second gas data module 103 may further include an electric control valve, and when the gas leakage and gas theft alarm module 101 determines that gas leakage or gas theft occurs, a valve closing instruction is sent to the electric control valve to cut off a gas service pipeline in time.
In a specific embodiment, the second gas data module 103 may employ an internet of things control valve with ultrasonic gas flow detection, such as the one disclosed in patent CN108717563A of the same applicant.
Since in actual use, gas leakage may occur in indoor gas delivery piping (for example, there is a case where the piping is damaged to cause leakage), and may also occur at gas-using terminal equipment. Therefore, in order to more accurately determine the location of the gas leakage in order to timely cope with the gas leakage, the first gas data acquisition module 102 may further include a gas flow sensor to sense the gas flow condition 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.
