Problems solved by technology

[0003] The test method without the help of test tools requires two testers to operate at the sending / receiving ends at the same time, the degree of automation is not high, and there are human errors in the comparison of data consistency
[0004] With the help of the test method of the test tool, the test tool sends the test data. After the test data passes through the system under test, it returns to the test tool. The test tool analyzes and compares the consistency of the sent and received data to determine the correctness of the communication data. The degree of automation is high, but there is a need for additional testing tools. During long-term testing, saving historical data requires a large amount of storage space; testing tools have a validity period of precision, and there may be unstable random events themselves, which will affect the credibility of test results. degree; the data of the system under test itself is not used as the test input, and the test data is still an external signal and other defects

Abstract

The invention relates to a test method and a test system for automatically counting data transmission correctness of a DCS (Distributed Control System), belongs to the field of industrial DCS platformsystem test, and solves the problem of data transmission correctness test, the method comprises the following steps: performing equipment configuration, variable configuration and algorithm configuration on the tested DCS; in a communication network formed by all devices of the DCS system, sending a configuration variable by any one or more communication nodes, specifying one communication node as a receiving node to receive the configuration variable, automatically detecting the configuration variable sent by each other communication node by the receiving node by using a data transmission detection algorithm included in a configuration algorithm of the receiving node, and counting the correctness of data transmission. The test system is high in automation degree, and human factor errorsare reduced; automatic statistics is realized, the storage space requirement is not high, and the method and system are suitable for long-term monitoring; no additional test tool is needed, and the reliability of the test result is high.

Description

technical field [0001] The invention relates to the field of industrial DCS platform system testing, in particular to a testing method and system for automatically counting the correctness of DCS system data transmission. Background technique [0002] The industrial DCS generally includes a network of multiple communication protocols, and the network used generally requires strong real-time communication, high stability, and relatively small complexity. Conventional tests commonly used to verify the correctness of DCS data transmission include tests without test tools and tests with test tools. [0003] The test method without the help of test tools requires two testers to operate at the sending / receiving ends at the same time, the degree of automation is not high, and there are human errors in the comparison of data consistency. [0004] With the help of the test method of the test tool, the test tool sends the test data. After the test data passes through the system under...
