Problems solved by technology

This makes the smart meter must be able to establish multiple TCP connections, but because the embedded software of the smart meter is mostly written in C language, and because C language is a language for process design, the application scenario of multi-channel connection must be It will lead to increased code complexity, reduced flexibility, and high defect rates.

Embodiment Construction

[0025] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings of this specification.

[0026] see figure 1 , figure 1 It is a schematic flow chart of the software design method of the present invention. The present invention proposes a kind of software design method of the GPRS multi-channel communication of smart electric meter, and it roughly comprises the following steps:

[0027] S101. Divide and classify the business processes involved in the GPRS communication of the smart meter to obtain multiple independent steps, and the software of each step realizes independent functions and independent interfaces.

[0028] S103. Classify and identify the parameters and methods involved in the GPRS connection channel of the smart meter to obtain an independent data structure. as well as

[0029] S105. When a remote TCP connection needs to be established, an object is instantiated with the above d...

Abstract

A software design method for GPRS multi-channel communication of a smart meter, comprising: dividing and classifying the business processes involved in the GPRS communication of the smart meter to obtain a plurality of independent steps, and the software of each step realizes independent functions and interfaces. Independent; classify and identify the parameters and methods involved in the GPRS connection channel of the smart meter to obtain an independent data structure; and when a remote TCP connection needs to be established, use the above data structure to instantiate an object, and Call each of the above software interfaces. The invention can improve the portability of software, reduce the workload of secondary development, and reduce the risk of software defects.

Description

technical field [0001] The invention relates to a software design method for smart meters, in particular to a software design method for GPRS communication of smart meters. Background technique [0002] With the development of smart grid, higher requirements are put forward for the diversity of functions of smart meters, among which remote communication is an important embodiment of the development of smart meters. At present, in the remote communication of the power grid, the communication mode of GPRS (General Packet Radio Service, General Packet Radio Service) is widely used in the smart grid because of its good stability and easy maintenance. However, with the increasing complexity of business logic, the single-channel communication mode of GPRS is difficult to meet new demands. For this reason, most smart meters will choose a multi-channel communication method, that is, a single smart meter will establish multiple TCP (Transmission Control Protocol, Transmission Contro...
