Abstract

The present invention relates to a wiring correctness detection method for a control cabinet of a distributed control system, which includes the following steps in sequence: assigning a value to a first decimal variable; If it is greater than the number of terminals, end the detection; apply a high voltage to the terminal whose serial number is the first decimal variable; read the voltage conditions on all terminals; make the first decimal variable equal to all The first decimal variable is incremented by one, and step S2 is repeated. The detection method of the invention can conveniently and quickly detect the correctness of a large number of wirings 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. 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] The object of the present invention is to provide a wiring correctness detection method for a control cabinet of a distributed control system, which can conveniently and quickly dete...
