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.

Abstract: The present invention provides a gas data transmission method based on a compound Internet of Things (IoT) and an IoT system. The method includes: sending, by a main sensor network sub-platform in a plurality of sensor network sub-platforms, gas data to a management platform; storing, by auxiliary sensor network sub-platforms, the gas data; when the management platform cannot receive the gas data sent by the main sensor network sub-platform, sending, by the management platform, interactive data to the main sensor network sub-platform; and when the main sensor network sub-platform does not respond to the interactive data, disconnecting, by the management platform, from the main sensor network sub-platform and establishing a connection with one auxiliary sensor network sub-platform to receive the gas data stored by the auxiliary sensor network sub-platform.

Abstract: The present invention provides a gas meter query method based on a compound Internet of Things (IoT) and an IoT system, and relates to the field of the IoT. The method includes: sending, by the first gas meter of a plurality of gas meters, when reading the data information corresponding to the second gas meter, the data information to the management platform via the sensor network platform; sending, by the management platform, the first control signal to the second gas meter via the sensor network platform, so that the second gas meter sends the first prompt information; sending the second prompt information to at least one of a plurality of service sub-platforms; and sending, by one of the service sub-platforms that receives the second prompt information, the second prompt information to the user sub-platform corresponding to the second gas meter.

Abstract: The present invention provides a gas meter energy-saving motivating method and Internet of Things (IoT) system based on a compound IoT, and relates to the field of the IoT. According to the gas meter energy-saving motivating method and IoT system based on the compound IoT, each of management sub-platforms searches for family population information associated with Identification (ID) information, calculates an average monthly gas usage amount according to monthly gas usage amounts and the family population information, sorts monthly per capita gas usage amounts in a preset area according to ID information in an ascending order, and sends a sorting result to a service platform; and then, the service platform sends reward information to user sub-platforms corresponding to top-ranked N monthly per capita gas usage amounts according to the sorting result.

Abstract: An automobile intelligent control instrument and an intelligent management system based on Internet of Things and belongs to an automobile instrument includes: a master controller of the automobile intelligent control instrument terminal based on the Internet of Things, wherein the master controller of the automobile intelligent control instrument terminal based on the Internet of Things is respectively accessed to many function modules inside an automobile and is further accessed to an information safety management module. The information safety management module is accessed to a signal base station, which is accessed to a remote control terminal. The master controller of the automobile intelligent control instrument terminal based on the Internet of Things transmits various data and control commands to the remote control terminal through the information safety management module and a mobile communication module.
