Abstract

The invention relates to a method for detecting wiring correctness of a control cabinet of a distributed control system. The method sequentially includes the following steps that firstly, a first decimalism variable is assigned; secondly, whether the number of the first decimalism variable is larger than that of terminals or not is judged, and if the number of the first decimalism variable is larger than that of the terminals, detection is completed; thirdly, high voltage is applied to the terminals with the serial number of the first decimalism variable; fourthly, the voltage status of all the terminals is read; fifthly, a first decimalism variable is made to be equal to the value obtained after adding 1 to the former first decimalism variable, and the second step is repeated. The invention further relates to a device for detecting wiring correctness of the control cabinet of the distributed control system. The method and device can conveniently and rapidly detect the correctness of a large quantity of wiring in the control cabinet of the distributed control system.

Description

technical field [0001] The invention relates to a method for detecting the correctness of wiring of a control cabinet, in particular to a method for detecting the correctness of wiring of a control cabinet of a distributed control system. In addition, the present invention also relates to a wiring correctness detection device of a control cabinet of a distributed control system for implementing the detection method. Background technique [0002] A distributed control system (DCS) in a large power plant typically has thousands of wires and twice as many terminals in each control cabinet. Manually checking the correctness of these wire connections is not only time-consuming and labor-intensive, but also prone to human error. In addition, manual inspection cannot find redundant wires that do not exist in the wiring table and are spliced ​​out. How to overcome the shortcomings of manual inspection is a long-standing problem in this field. Contents of the invention [0003] ...
