Description

technical field

[0001] The invention relates to a communication method, in particular to a communication method between two cores of an intelligent electric energy meter based on electric quantity synchronous processing. Background technique

[0002] With the advancement of Internet technology, people's daily life is gradually changing. Among them, the development of electrical appliances is changing with each passing day, the electricity consumption has increased significantly, the proportion of electricity bills in daily expenses has increased significantly, and the accuracy requirements for electricity metering are gradually increasing. As a result, the IR46 standard issued by the International Legal Metrology Organization requires: "The legal measurement part (electric energy measurement data and clock data) is not affected by other parts", and the dual-core smart energy meter came into being. The measurement core is responsible for measuring electricity consumption. Th...
