Problems solved by technology

[0004] The above-mentioned functional testing of the distributed control system using the test device has the following disadvantages: on the one hand, the distributed control system contains tens of thousands of execution devices, and it will inevitably cause heavy work when connecting the execution device or the field control station to the test device. and may require multiple test fixtures, therefore, higher testing costs
On the other hand, in the process of functional testing, the test device cannot complete operations and view status on the control server in the management level network, but can only be completed by the control server
Testers need to assign the input data of the execution device on the test device, and also need to perform command operations and view status on the control server, which makes the test efficiency low

Abstract

An embodiment of the invention provides function testing equipment, a control server and a function testing method of a distributed control system. The function testing equipment is in communication connection with one or a plurality of control servers through a management-grade network of the distributed control system. The function testing equipment comprises the components of a test case acquiring unit which is used for acquiring a test case that comprises testing step data; an execution instruction generating unit which is used for generating an execution instruction according to an execution operation and input data in the testing step data for each package of testing step data; an execution instruction execution unit which is used for transmitting the execution instruction that is generated by the execution instruction generating unit to the control server and receiving an execution result of the execution instruction from the control server; and a testing result determining unit which is used for determining the testing result of the execution instruction according to the execution result of the execution result received by the execution instruction execution unit and an anticipated output result of the execution instruction. The function testing equipment, the control server and the function testing method of the distributed control system can save a wire between execution equipment and a testing device in prior art.

Description

technical field [0001] The invention relates to distributed control technology, in particular to a function testing device, control server and method of a distributed control system. Background technique [0002] In the field of nuclear power plant control, the implementation of process system control logic is a key task for the automatic and safe operation of the distributed control system (DCS (Distributed Control System) control system). It is particularly important to verify the correctness of the control logic in the testing phase. [0003] Currently, if figure 1 As shown, in the function test, a test device is connected to the on-site control station or execution equipment, and the test device is connected to the control server in the distributed control system through a cable. The test device simulates the execution device (such as a sensor) to send a signal, and the signal is transmitted to the control server through the cable. The test device receives the executi...
