Abstract

The invention relates to the test equipment of a group control system control cabinet. The equipment comprises a plurality of test circuits under different test processes and a change-over switch. Theplurality of test circuits are connected to the change-over switch. The plurality of test circuits are connected to the tested controller of a control cabinet. The change-over switch is used for switching the test processes of the tested controller. The test circuits are used for carrying out simulation testing corresponding to the test processes on the tested controller according to the test process of the change-over switch lock switching. The test equipment is taken as the simulation equipment of an electric butterfly valve. The tested controller is connected to the test circuit corresponding to the test process of the test equipment. According to the switching state of the change-over switch, the test circuit corresponding to the test process carries out the simulation test corresponding to the test process on the tested controller. Through the test equipment, the control conditions of the tested controller to the electric butterfly valve under various field conditions can be simulated and detected, and test convenience is improved.

Description

technical field [0001] The present application relates to the field of controller testing, in particular to a testing device for a control cabinet of a group control system. Background technique [0002] At present, the water system in the industry uses the control cabinet of the group control system to monitor the operation status of each device. Therefore, whether the controller in the control cabinet of the group control system is running normally and whether the programming logic in the controller is correct will affect the entire water system. normal operation of the system. [0003] The controller in the traditional control cabinet and the test of the programming logic in the controller pass the input and output mode of the corresponding interface of the controller, and give the corresponding digital or analog input and output control signals to check the normal operation of the controller and the program logic. However, the traditional test method cannot simulate and...
