Background

With the rapid development of the network and communication industry, the communication and network capacity increases in geometric quantity, and the wiring difficulty is further improved.

The general routing flow is: firstly, according to the information point location distribution in the secondary lifting diagram, numbering and recording an ID of each information point location; marking stickers are manufactured according to the coded numbers and are pasted at the two ends of the pipeline to be penetrated, the wire to be distributed is distributed into the wire pipe or the wire groove, and the module is connected well; and finally, recording the ID of the subsystem module termination cable of the management room and the ports from 1 to 24 of the 24-port distribution frame in a one-to-one mode, and recording the ID of the subsystem module termination cable of the working area and the room position. In the process, ID coding records are recorded once, and corresponding records of two IDs and one label are pasted once. Most of the records are often incomplete due to various reasons, such as mark falling in the wiring process, and incomplete records; carelessness of wiring personnel loss of records; the job hand-off record is lost or incomplete; the computer is lost when the replacement record is lost, and so on. The label may also be removed and fall off due to dust, thread rubbing, pulling, or prolonged periods of time. The incomplete record and the drop of the mark, when the project finishes the back test and the later network maintenance, modification, often because look for the position and will be originally orderly wiring tear open, tear into seventy-eight falls, the whole management room has just become a great "spider web" long-lasting.
