Today, I will introduce a national invention authorized patent-a gas meter fault prompt method and an Internet of Things system based on the composite Internet of Things. The patent was applied for by Chengdu Qinchuan Internet of Things Technology Co., Ltd., and the authorization was announced on February 16, 2018. The present invention relates to the field of Internet of Things, in particular to a method for prompting a gas meter fault based on a composite Internet of Things and an Internet of Things system. People’s daily cooking fuels have been transformed from wasteful and polluting conventional energy sources such as wood and coal to the use of natural gas and gas, and even electricity and other clean energy sources. However, in the use of gas, the gas meter may malfunction due to external magnetic interference and insufficient battery power. For users without maintenance experience, if some simple faults occur, they need to call the maintenance personnel of the gas company to perform repairs on site. This results in a lot of waste of labor and time costs, and low efficiency. In view of the above problems, the purpose of the present invention is to provide a gas meter fault prompt method and an Internet of Things system based on a composite Internet of Things. The invention provides a gas meter fault prompting method based on a composite Internet of things. The gas meter fault prompting Internet of Things system based on the composite Internet of Things includes multiple user sub-platforms, a service platform, a management platform, and multiple sensor network sub-platforms. Platforms and multiple objects are divided into platforms. The object sub-platform includes gas meters, and the gas meter fault notification method based on the composite Internet of Things includes: each gas meter self-checks its own operating status information in real time to determine whether it is malfunctioning; if the gas meter itself fails, it will run Status information is sent to the management platform through the corresponding sensor network sub-platform; the management platform queries the fault type and fault solution based on the operating status information and the preset fault query table; the management platform sends the fault type and fault solution to the corresponding Service platform: The service platform sends the fault type and fault solution to the corresponding user sub-platform for display. The gas meter fault prompting system based on the composite Internet of things includes multiple user sub-platforms, one service platform, one management platform, multiple sensor network sub-platforms, multiple object sub-platforms, multiple user sub-platforms, and one service platform , One management platform, multiple sensor network sub-platforms, and multiple object sub-platforms communicate and connect in turn. The object sub-platforms include gas meters. Each gas meter is used to self-check its own operating status information in real time to determine whether it appears Failure; if the gas meter itself fails, the gas meter is also used to send the operating status information to the management platform through the corresponding sensor network sub-platform; the management platform is used to query based on the operating status information and the preset fault query table Fault types and fault solutions; the management platform is also used to send fault types and fault solutions to the corresponding service platform; the service platform is used to send fault types and fault solutions to the corresponding user sub-platforms for display. Compared with the prior art, the gas meter fault prompt method and the Internet of Things system based on the composite Internet of Things provided by the present invention are used for real-time self-checking of its own operating status information through each object sub-platform to determine whether it is malfunctioning; The platform is used to query the fault type and fault solution based on the operating status information and the preset fault query table; and send the fault type and fault solution to the corresponding user sub-platform display through the service platform, and the user can display it in the user sub-platform. The platform knows and checks the types of gas meter failures and failure solutions in time, so that they can repair and handle some simple failures of the gas meter independently, without having to ask gas company personnel to handle them on site, saving time and labor costs.
