Description

Urban rail transit 5G antenna optical cable installation auxiliary device that colds pressing
Technical Field
The invention relates to the technical field of cold-pressing installation of optical cables, in particular to an auxiliary device for cold-pressing installation of an urban rail transit 5G antenna optical cable.
Background
In recent years, the fifth generation mobile communication system 5G has gradually become a hot spot in research in the communication industry and academia. There are two main driving forces for the rapid development of 5G from the current development. On one hand, a fourth generation mobile communication system 4G of long term evolution is completely commercial, and has been pushed to the future in the face of deeper research; on the other hand, in response to the explosive increase in the demand of mobile data users, the existing mobile communication systems may not satisfy the future demand, and the development of a new generation 5G system is urgently needed from the present situation.
The main advantage of 5G networks is that the data transmission rate is much higher than that of the previous 4G networks, up to 10Gbit/s, faster than the current wired internet, 100 times faster than the previous 4G lte cellular networks. Another advantage is lower network delay (faster response time), below 1 millisecond, and 30-70 milliseconds for 4G. Due to faster data transmission, the 5G network will not only serve the handset, but will also become a general home and office network provider, competing with the cable network provider. The civil communication of rail transit in Haoyote city is called, the 5G network is applied to the subway industry in China for the first time, and the civil communication has profound significance for the development of rail transit 5G and indoor 5G (such as office buildings, commercial squares and the like) as a 5G network test point area.
The 1 st line of the subway in the Hehaote city is the first 5G antenna installation application of the domestic subway, and according to the field survey, 5G is different from 4G, and indoor leaky cable coverage needs to be changed into optical cable coverage to satisfy the data magnitude transmission rate demand, and the general hot melt mode of tradition needs to use the heat sealing machine, and the hot melt defect lies in that the instrument is expensive, needs to continue the power consumption, and the maintenance cost is higher, and professional welding personnel welding cost is higher, and the operation place is restricted. Especially, civil antenna terminal point location is many, need be under construction on the furred ceiling after the fitment furred ceiling is accomplished, and battery continuation of the journey is limited, and it is inconvenient to get the electricity and the heat sealing machine is put, is unfavorable for site operation, and the cost is higher, consequently calls for Haoyite 5G antenna to continue and adopts the optic fibre cold joint mode, uses the LC connector of cold pressing terminal, adopts V type wedge to be connected optic fibre and LC connector. I place professional technical personnel into, through the supervision personnel of mobile company to train the study to 5G technique, select the west two ring station of model station, the gas station of no tower in back to carry out equipment and antenna installation construction. I have counted the antenna installation condition, and the on-site rate is relatively poor, leads to the antenna rate of going up to be only 82.68%, improves the antenna qualification rate, and it is the key in the work progress to reduce reworking.
Aiming at the problem of low antenna wire rate, subject group members carefully carry out on-site comparison and analysis and deeply discuss and refine the problem, and find that the three problems of uneven optical fiber root protective sleeves, gaps between optical fibers covered by an optical fiber clamp and bare fibers exceeding a window of an LC (liquid crystal) connector are main reasons influencing the primary qualification rate of 5G indoor antenna installation and debugging.
