Background
In the production process of the electric device of the cabinet, a large number of cables need to be manufactured so as to realize the electric interconnection of all units in the cabinet. The cable lengths vary from unit to unit, since the location of the beginning and end of the cable and the path traveled by the cable are not exactly the same.
how to accurately and quickly determine the length of the cable in the cabinet equipment becomes a problem to be solved urgently in the field; in order to obtain the length of each unit cable, the traditional method is that a tool cable is used for manually simulating the space path of the corresponding cable on a cabinet object, and then the tool cable is taken out to measure the length of the cable; with the wide application of three-dimensional modeling of mechanical structures, three-dimensional modeling of cable wiring is also developed; and drawing the space path of the cable through three-dimensional modeling so as to obtain the length of the cable.
the defects of the prior art are as follows: when manual comparison measurement is performed on a cabinet object, an operator needs to stretch into a narrow space in the cabinet for multiple times, the operation is difficult, and the labor capacity is large; the new counter cabinet equipment with similar structure needs repeated measurement, and the efficiency is lower; in addition, the space path compared with the tool cable cannot be completely the same as the final actual wiring path, so that a certain error exists between the space path and the actual required cable length; even if the same person is compared twice on the same equipment, the obtained two measurement results have errors. In the stage of electric appliance production of the cabinet, each unit in the cabinet is generally not actually installed, and only the position of the unit can be roughly estimated, so that the error is larger. When the cable is in three-dimensional modeling, the three-dimensional model is more complicated to establish and modify because the cable is in an irregular shape; in addition, when new cabinet equipment with similar structures is used, the three-dimensional modeling of cable wiring still needs more repetitive work, the working efficiency is influenced, and the popularization is difficult.

Specifically, after determining an initial end unit and a terminal end unit of a cable connection relationship, the three parts of the intermediate cable section, the initial end cable section and the terminal end cable section can be known, the length of the intermediate cable section can be further known to comprise four parts, and the sum of the parameters of the four parts can be directly calculated in a unit parameter table to obtain the length of the intermediate cable section.
For example, a cabinet apparatus, comprising the following units: the computer A1, the computer B2, the switch, the keyboard, the display and the top cover plate are all arranged on the framework; the top cover plate can be opened upwards, and the computer A1, the computer B2, the switch and the keyboard can be respectively pulled out or pushed in along the framework horizontally; the computer A1, the computer B2 and the switch are respectively provided with a wire-following frame, one end of the wire-following frame is fixed on the framework, and the other end of the wire-following frame is fixed on the corresponding unit.
