Description

[0002] In the industrial power construction industry, electrical equipment and high and low voltage switch cabinet control lines cannot do without the use of line number machines. The conventional line installation and debugging method is to attach cable labels - place cables - put on number tubes - connect wires - calibrate wires. The installation and debugging work in this process are separate. There are many cables in the on-site cabinets and junction boxes, and cable labels often fall off and the cables are connected incorrectly at both ends. When calibrating the line, the debugging personnel often find wiring errors, and then inform the installers to modify them. When the installers modify, they generally need to connect a light generator at one end of the control line, and the detection light generated by the light generator is transmitted to the other end. Then the two installers communicate through the intercom to determine the corresponding ends of the control cable. This method is inefficient and is also prone to errors in communication.
