Intelligent meter display parameter reading and writing method

Abstract

The invention relates to an intelligent meter display parameter reading and writing method. The intelligent meter display parameter reading and writing method is characterized by comprising the stepsof: (1), waiting an upper computer to send a display parameter reading / writing data frame, if the MCU of an electricity meter receives the display parameter reading / writing data frame, entering the next step, and otherwise, continuously waiting; and (2), according to the class name in the display parameter reading / writing data frame sent by the upper computer, calling a reading and writing function class for executing the corresponding class name by the MCU of the electricity meter, querying a pre-set form in the MCU of the electricity meter through a look-up method by the reading and writingfunction class, so that a corresponding parameter reading and writing function pointer and a corresponding parameter operation address are obtained, and furthermore, executing a corresponding parameter reading and writing function according to the corresponding parameter reading and writing function pointer. The intelligent meter display parameter reading and writing method is simplified in algorithm and relatively high in efficiency; and furthermore, display function expansion is convenient.

Description

technical field [0001] The invention relates to the technical field of smart meters, in particular to a method for reading and writing display parameters of smart meters. Background technique [0002] The smart meter display module is to display in real time according to the display items and parameters set by the customer through the host computer, as well as various states of the meter, and provide the most intuitive data and information to the customer to obtain the current various data and states of the meter. [0003] With the gradual improvement of power grid construction, smart meters have more and more functions, and their display content is becoming more and more complex. However, at present, the reading and writing methods of the display parameters of the smart watch are not concise enough, and the reading and writing functions of the corresponding display parameters need to be entered through complex algorithms, which is inefficient, and when the display function ...

Problems solved by technology

[0003] With the gradual improvement of power grid construction, smart meters have more and more functions, and their display content is becoming more and more complex.

However, at present, the reading and writing methods of the display parameters of the smart watch are not concise enough, and the reading and writing functions of the corresponding display parameters need to be entered through complex algorithms, which is inefficient, and when the display function needs to be expanded, the algorithm needs to be redesigned, which is inconvenient to display function extension
