Memory monitoring method, device, system and storage medium of electric energy meter

Abstract

The present application relates to a method, device, system and computer-readable storage medium for monitoring the memory of an electric energy meter. The method includes: obtaining the base address of the compiler on the host computer and the variable name storage address of the energy meter processor reading and writing data through the host computer; and then calculating the energy meter according to the preset simulation memory address, base address and variable name storage address The reading and writing data of the device is located at the mapping address on the emulation memory device and sends the mapping address to the energy meter processor, which supplies power to the energy meter processor to read and write data. After the data is read and written for a preset period of time, the host computer based on the above mapping The address monitors the emulated memory device. By adopting this method, the real memory of the electric energy meter can be assigned to the external simulation memory device to run without occupying the real memory of the electric energy meter, and the upper computer can obtain data from the external simulation memory device in real time to monitor the external simulation memory device. It also realizes the monitoring of the real memory of the electric energy meter by the host computer.

Description

technical field [0001] The present application relates to the technical field of power equipment testing, in particular to a method, device, system and computer-readable storage medium for monitoring the memory of an electric energy meter. Background technique [0002] The energy meter is an instrument used to measure electric energy. When the energy meter is connected to the circuit under test, the program in the processor of the energy meter starts to run. During the operation of the program, data such as voltage, current, power, etc. will be generated. These operating data are stored by the memory in the processor, and the processor and host computer can read various operating data of the electric energy meter from the above memory, which provides a reliable basis for judging the operating condition of the electric energy meter , so the operation of the memory has a greater impact on the overall operation of the energy meter, and it becomes very necessary to monitor the m...
