Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method for separating the legal metering program and the non-legal function program of the electric energy meter, so as to solve the problem that the electric energy meter in the prior art integrates the metering and other functions, and the change of the functional part will easily affect the metering. function, its damage or failure will easily lead to damage or failure of the metering part; the legal metering and non-legal function programs are still in the same single-chip microcomputer, if the program is not separated, the subsequent management core software program upgrade will easily affect the legal metering of the metering core function, causing technical problems such as measurement inaccuracy events

Embodiment Construction

[0023] A method for separating legal measurement programs and non-legal function programs of electric energy meters, which includes: 1) hardware architecture setting, 2) software architecture setting, and 3) management core software upgrade.

[0024] The setting of the hardware architecture divides the energy meter into a metering core and a management core; the metering core and the management core include a platform layer and a component layer (extension layer) respectively. Transmission, each component layer (extension layer) is independent of each other in hardware. As a base meter, the metering core mainly accumulates basic electric energy data, and has functions such as data storage, pulse indication, total loss of voltage, abnormal power supply event detection, etc. The data interacts with the management core through the 698 protocol for external display, communication, and event recording. The independent RS485 interface of the metering core can only be read, and does ...

Abstract

The invention discloses a method for separating a metering program of an electric energy meter method and an illegal functional program. The method comprises the following steps: 1, dividing the metering core and the management core into a platform layer and a component layer respectively; 2, configuring a metering MCU in the platform layer of the metering core, configuring a management MCU in theplatform layer of the management core, and transmitting data between the metering MCU and the management MCU through an SPI interface circuit; 3, installing a metering procedure of a metering methodon that metering MCU; installation of illegal function program in management MCU. The invention solves the problem that the electric energy meter of the prior art integrates the metering and other functions, the change of the function part can easily affect the metering function, and the damage or failure of the metering part can easily lead to the damage or failure of the metering part; subsequent software upgrade of the management core can easily affect the legal metering function of the metering core and cause technical problems such as metering misalignment events.

Description

technical field [0001] The invention belongs to the technical field of electric energy metering, and in particular relates to a method for separating legal metering programs and non-legal function programs of electric energy meters. Background technique: [0002] The existing operating electric energy meter integrates metering and other functions. Considering the manufacturing process and cost, its legal metering and non-legal function programs are in the same single-chip microcomputer. The change of the functional part will easily affect the metering function, and its damage or failure is easy. Cause damage or failure of the metering part; considering the manufacturing process and cost, the legal metering and non-legal function programs are still in the same single-chip microcomputer, if the program is not separated, the subsequent management core software program upgrade will easily affect the legal metering function of the metering core , causing a measurement inaccuracy ...
