Abstract
The present invention relates to the field of Internet of Things (IoT), and provides a gas leakage detection method based on a compound IoT and an IoT system. According to the gas leakage detection method based on the compound IoT and the IoT system provided by the present invention, whether a gas pipeline of a user has gas leakage or not is judged via a user participation manner, the judgment manner is intelligent, the judgment result is accurate and thus the gas safety of the user is guaranteed.
Claims12
A gas leakage detection method based on a compound Internet of Things (IoT) that includes multiple devices connected wirelessly via the Internet, wherein the method is applied to an IoT system;
- the IoT system comprises a user platform, a management platform, an object platform, a plurality of sensor network sub-platforms and service sub-platforms;
- the object platform comprises a gas meter;
- the service sub-platforms comprise at least one of a gas company service sub-platform, a government service sub-platform or a social operator service sub-platform;
- and the method comprises:
- sending, by the user platform, a detection command to a service sub-platform, wherein the detection command comprises a time period;
- sending, by the service sub-platform, the detection command to the management platform;
- sending, by the management platform, a detection instruction to the gas meter via at least one of the plurality of sensor network sub-platforms according to the detection command;
- in response to the detection instruction, sending, by the gas meter, gas usage data to the management platform via the sensor network sub-platforms at a preset time interval within the time period;
- judging, by the management platform, whether the gas usage data uploaded by the gas meter changes or not during the time period, and when the gas usage data changes, judging, by the management platform, whether to send a valve closing instruction to the gas meter or not via at least one of the plurality of sensor network sub-platforms;
- and when receiving the valve closing instruction, closing, by the gas meter, a valve in response to the valve closing instruction;
- wherein the service sub-platforms comprise at least the gas company service sub-platform and the social operator service sub-platform;
- and the step of when the gas usage data changes, judging, by the management platform, whether to send a valve closing instruction to the gas meter or not via at least one of the plurality of sensor network sub-platforms comprises:
- when the time at which the gas usage data changes falls within a preset time range, sending, by the management platform, the valve closing instruction to the gas meter via at least one of the plurality of sensor network sub-platforms;
- and sending, by the management platform, prompt information to both the gas company service sub-platform and the social operator service sub-platform.
