Function test method for loop measurement and control terminal and client

Abstract

The invention discloses a function test method and client for a loop measurement and control terminal, and the technical scheme comprises the steps: integrating the functions of single-step test, automatic test, message analysis and the like, and achieving the function test in different use environments through an external file in a specific format on the basis of not changing the core architecture of software. The software testing method and the client provided by the invention can meet the testing requirements of professional testing personnel on the loop measurement and control terminal, can also meet the requirements of field operation and maintenance personnel on terminal data analysis and function testing, and can adapt to various function tests according to configuration files under the condition that the software structure is not changed; the efficiency of terminal function testing is improved, and the difficulty and time of field installation and debugging are reduced.

Description

technical field [0001] The invention relates to the technical field of loop measurement and control terminal testing, in particular to a function testing method and a client terminal for loop measurement and control terminals. Background technique [0002] With the development of science and technology, industrial control is also developing in the direction of individuation, intelligence, and dataization. The status of the upper computer is becoming more and more important, and how to quickly collect, store, and utilize data is especially important. [0003] The Modbus communication protocol is an industrial automation bus communication protocol. Its characteristics are standard, development and free, and it supports data communication of thousands of industrial intelligent instrumentation manufacturers, and supports multiple communication interfaces such as RS232, RS85, TTL, optical fiber and wireless. , the protocol is open, the format is easy to understand, and it is wide...

AI Technical Summary

Problems solved by technology

[0004] Conventional test clients usually have a single function. Either the test process uses manual control of the upper computer software to issue test commands to detect the terminal, or the manual combination of test messages is sent to the serial port software to detect the terminal. Sending and receiving messages often need to be pasted out Parsed manually or with a separate tool

For a new type of terminal such as a loop measurement and control terminal, both the protocol and the function have certain uniqueness. From the terminal manufacturer to the maintenance personnel of the power company, there are no ready-made tools to support the rapid testing, debugging and use of the equipment, and a comprehensive solution is urgently needed.
