Communication method, device and storage medium for dual-core electric energy meter

Abstract

This application discloses a communication method, device and storage medium for a dual-core electric energy meter. The method includes: dividing the message sent by the management unit into a message header and a message body, and sending the message header and message body to The metering unit of the double-core electric energy meter; formulate the first response message format and the second response message format of the metering unit, and when the response data of the metering unit is ready, reply the first response message format to the management unit; When the response data of the unit is not ready, reply to the management unit according to the second response message format. This application solves the problem of overrun of SPI high-speed communication data in the prior art, but there is a slow simulation speed, and when the measurement unit sends data to the management unit through the interrupt mode, it is interrupted by a higher priority interrupt due to interruption, resulting in SPI The wrong data is sent by the bus, which causes the management unit to receive the wrong byte data, which makes the final message distorted.

Description

technical field [0001] The present application relates to the technical field of superconducting power, in particular to a communication method, device and storage medium for a dual-core electric energy meter. Background technique [0002] The dual-core electric energy meter separated by law is composed of a management unit and a metering unit. The management unit and the metering unit are connected through a communication interface. The commonly used communication interface in the electric energy meter is UART. When the amount of data exchanged between the management unit and the metering unit is increasing When it is large, the communication rate of UART used in dual-core communication is difficult to reach the communication rate of 1Mbps, and the communication rate of UART is difficult to meet the needs of high-speed communication, and UART needs the rate matching of the two parties to communicate, and the two parties must set the same communication rate.

Problems solved by technology

[0004] This application provides a communication method, device and storage medium for a dual-core electric energy meter, which solves the problem of overrun of SPI high-speed communication data in the prior art, but there is a problem that the simulation speed is slow, and the metering unit sends to the management unit through an interrupt The data is interrupted by a higher priority interrupt due to an interrupt, causing the SPI bus to send wrong data, causing the management unit to receive wrong byte data and distorting the final message.
