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

Abstract

The invention relates to an electric energy meter memory monitoring method, device and system and a computer readable storage medium. The method comprises the steps of obtaining a base address of a compiler on an upper computer and a variable name storage address of read-write data of an electric energy meter processor through the upper computer; calculating a mapping address of the read-write data of the electric energy meter processor on the simulation memory device according to a preset simulation memory address, a base address and a variable name storage address, sending the mapping address to the electric energy meter processor, reading and writing the data by the electric energy meter processor, and after data reading and writing are carried out for a preset time period, monitoring the simulation memory device by the upper computer based on the mapping address. By adopting the method, the real memory of the electric energy meter can be appointed to the external simulation memoryequipment to operate under the condition that the real memory of the electric energy meter is not occupied, and the upper computer can acquire data from the external simulation memory device in real time to monitor the external simulation memory device, so that the real memory of the electric energy meter can be monitored by the upper 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...
