According to the requirements of the IR46 standard, which is the international recommendation issued by the International Organization of Legal Metrology, if the structure and procedure of the energy meter as a measuring instrument are changed, the type evaluation should be re-evaluated, which means that the program of the energy meter cannot be remotely upgraded online.
The design scheme of the existing smart energy meter is to design functions such as metering, storage, clock, display, billing, fee control, communication, event recording, and remote upgrade as a whole. Once the subsequent functions need to be changed, they will have to be replaced Energy meter, causing great waste
At the same time, the energy meter designed to integrate the metering and management parts will directly affect the accuracy of the metering part when the management part of the software or hardware encounters a loophole, making the amount of electricity untraceable and easily causing power disputes

The invention relates to an electric energy meter with an independent metering part and a management part, including a metering control module and a management control module. The metering control module is used to collect and calculate electric energy data, and send the collected and calculated electric energy data to the The management control module; the management control module is used to realize rate control, and calculate billing data according to the rate and the received electric energy data. The invention solves the problem that the management function of the smart electric energy meter needs to be continuously improved in the prior art, and the problem that the management part and the metering part influence each other, overcomes the existing need to change the function of the electric energy meter by replacing the electric energy meter, and solves the problem of the electric energy meter. The shortcomings of high meter update cost and cumbersome upgrade process also increase the operational stability of the electric energy meter, and the reliability and traceability of the metering part of the data.
Description
technical field [0001] The invention relates to the field of electricity service, in particular to an electric energy meter with an independent metering part and a management part and a verification method thereof. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. According to the requirements of the IR46 standard, that is, the international recommendation issued by the International Organization for Legal Metrology, if the structure and procedure of the energy meter as a measuring instrument are changed, the type evaluation should be re-evaluated, which means that the program of the energy meter cannot be remotely upgraded online arbitrarily. The design scheme of the existing smart energy meter is to design functions such as metering, storage, clock, display, billing, fee cont...
