Methods and systems for energy measuring based on natural gas data of smart gas meter

A method for energy measuring based on natural gas data of a smart gas meter, wherein the method is implemented based on a management platform of a gas Internet of Things IoT),

• the gas IoT includes a user platform, a service platform, the management platform, a sensor network platform, and an object platform that sequentially interacts;
• the management platform is set on a cloud platform to form a cloud platform in the gas IoT;
• a plurality of the cloud platforms in the gas IoT interact with at least one cloud platform outside the gas IoT;
• computation outside the gas IoT is performed through the cloud platform outside the gas IoT;
• the management platform is configured to:
• obtain a natural gas transmission and distribution pipeline network based on at least one of the user platform, the service platform, the sensor network platform, the object platform, and/or an external data source and determine a plurality of gas sources for supplying gas to an object user in the natural gas transmission and distribution pipeline network;
• for each gas source:
• determine a gas transmission route from the gas source to the object user, wherein the gas transmission route is a route from an object gas pressure detection node between the gas source and the object user to the object user, and the object gas pressure detection node is a gas pressure detection node closest to the object user in a communication route between the gas source and the object user;
• obtain a gas transmission feature vector of the gas transmission route according to a flow of a plurality of users in the natural gas transmission and distribution pipeline network, a gas pressure of natural gas of the object gas pressure detection node, and a pipeline network topology data;
• determine a gas pressure of the natural gas provided to the object user by each gas source based on the gas transmission feature vector of the gas transmission route;
• determine a gas transmission ratio of each gas source to the object user based on the gas pressure of the natural gas provided to the object user by each gas source;
• determine a calorific value of mixed natural gas used by the object user based on the gas transmission ratio of each gas source to the object user;
• and
• determine an energy measurement data of the object user based on the calorific value of the mixed natural gas and a consumed gas volume of the object user;
• and
• the management platform sends the energy measurement data to the user platform configured in a regional pipeline network center through the service platform;
• and the user platform performs gas energy measurement of the smart gas meter based on the energy measurement data.
