The invention discloses an electric energy meter RTC-based metering self-calibration method, on one hand, calibration point serial numbers and table body output parameters are simultaneously sent to all to-be-calibrated electric energy meters in a broadcast mode, and the meter calibration process is completed by an in-meter automatic meter calibration program, so that each to-be-calibrated electric energy meter can be calibrated at the same time; time consumed by meter position switching is saved, and meter calibration efficiency is improved. And on the other hand, the calculation of the metering error and the compensation value of the register corresponding to the metering chip is automatically completed by the ammeter to be calibrated, so that the functional requirements of the meter calibration table body are reduced, and the stability and reliability of the meter calibration table body are improved. In addition, the invention also provides a metering self-calibration device and equipment based on the RTC of the electric energy meter, and a readable storage medium, which have the above effects.
Description
technical field [0001] The present application relates to the field of smart meters, and in particular, to a method, device, equipment and storage medium for metering self-calibration based on an energy meter RTC Background technique [0002] With the rapid development of the national economy, electricity has become the most important energy source for the country. As far as civil electricity is concerned, with the enrichment of people's material living standards, the demand for electricity is also increasing, and the demand for the use of electric energy meters also increases, and the production efficiency of electric meter companies also increases. [0003] At present, the electric energy meter needs to be calibrated for its electric energy measurement error before leaving the factory. The mainstream meter calibration method is to connect the pulse signal line of the calibration table to the pulse port of the electric energy meter, and the calibration table body detects th...
