Problems solved by technology

At present, the testing of thermal control logic in power plants mainly adopts manual testing methods, that is, manually setting input test cases according to the testing process, observing and recording the output results, and then manually judging whether the test results are correct. Each process to be tested is relatively familiar; completely manually setting input variables and recording output variables is not only time-consuming, labor-intensive, and inefficient, but also prone to human errors, resulting in incorrect input variables or incorrect output results records, etc.

Embodiment 1

[0030] Such as figure 1 As shown, a control logic testing system of the present invention includes a user information verification server 11 , a standard test case management server 12 , a test result management server 13 and an application workstation 14 .

[0031] The application workstation 14 connects the user information verification server 11, the standard test case management server 12 and the test result management server 13 through the network, and is the core component of the entire test system. All requests and actions in the control logic testing process are sent and executed by the application workstation 14 .

[0032] The user information verification server 11 is used to process the user information verification request sent by the application workstation 14 . The user information verification server 11 accepts the request, verifies the user's operation authority according to the request, and returns the result to the workstation 14 .

[0033] The standard test...

Embodiment 2

[0046] Such as image 3 Shown, adopt the test method of a kind of control logic of test system described in embodiment 1, it comprises the following steps:

[0047] Step S1: call the standard library generation module 142 to create a standard test case, the standard test case refers to a test case with versatility, which can be reused for test cases of different models under test, which includes test model input points, output points, For information such as tolerance, execution time, input point value and output point expected value, the standard test case is usually pre-created and saved to the standard test case management server 12;

[0048] Step S2: Convert the control logic algorithm module into function code through the model conversion module 143, generate the input point list file, the output point list file and the algorithm module parameter list file, integrate the function code and compile it into a test model that can interact with the test engine module 144 . T...

Abstract

The invention provides a test system and a test method for a control logic. The test system comprises a user information verification server, a standard test case management server, a test result management server and an application workstation. The application workstation comprises a user authority verification module, a standard base generating module, a model conversion module and a test engine module. The application workstation connects the user information verification server, the standard test case management server and the test result management server through a network. The test system and the test method for the control logic according to the invention can automatically generate test causes and perform a testing verification operation in a batch manner, thereby greatly reducing manual operation, making a user finish the control logic testing verification operation conveniently and quickly, reducing the number of man errors and improving testing quality and testing efficiency.

Description

technical field [0001] The invention relates to the field of power plant thermal control, in particular to a control logic testing system and method. Background technique [0002] In power plant design, the control logic design of the thermal control system is an important link, which is directly related to whether the power plant runs smoothly and safely, and whether emergencies can be dealt with in time and other major issues. When designing a control system, first draw the control logic diagram of the process control system according to the requirements of the control process, then carry out the configuration design of the control system according to the control logic diagram, and finally test and verify the completed control logic to ensure the design accuracy. The control logic is as expected. At present, the testing of thermal control logic in power plants mainly adopts manual testing methods, that is, manually setting input test cases according to the testing process...
