Description
Technical field
The present invention relates to a kind of network equipment construction method of installation and line holder, particularly a kind of 3G (Third Generation) Moblie network TD-SCDMA base station only shaft tower BBU-RRU optical cable construction method and curved line holder.
Background technology
The 3G (Third Generation) Moblie TD-SCDMA technology; As the first 3G (Third Generation) Moblie international standard of China with independent intellectual property right; Adopted a lot of technology such as smart antenna, time-division and sign indicating number branchs technology, uplink synchronous, up-downgoing be asymmetric, and characteristic services application that these technology are TD-SCDMA has brought original advantage.The 3G (Third Generation) Moblie TD-SCDMA technology began trial run in 2007; Whole nation provincial capital will build the second stage of the project in the end of the year 2008; The third stage of the project was built in the beginning nationwide in 2010, and its construction speed is unprecedented, as the brand-new communication technology of a generation; Comprised a large amount of new equipment, its construction technology, construction method and previous generation mobile communication technology are very different and improve.
The TD-SCDMA base station architecture is taked and 2G (second generation mobile communications network; Base Band Unit)+RRU (Remote Radio Unite: framework remote radio unit (RRU)) the GSM network) the diverse framework in base station, TD-SCDMA have adopted the base station BBU (Building Base band Unit:.BBU equipment generally is installed in the machine room, and RRU equipment generally is installed on the outer communication tower of machine room, and BBU is connected through optical cable with RRU and realizes communication, so the effect of optical cable of BBU and RRU of connecting is of crucial importance.The kind of base station communication iron tower is a lot, and is wherein more with the quantity of only shaft tower.Therefore how the good optical cable of better protection, it is the background of this product of research and development that reliable wireless signal is provided.
At the beginning of TD-SCDMA builds; What engineering construction was mainly used for reference is the construction method of second generation mobile communication (GSM); But because the TD-SCDMA base station is very different with the principle of GSM base station: what be connected antenna and equipment in the GSM base station is to have only feeder line, and connection antenna and equipment has comprised optical cable and power lead, the intensity of feeder line ultraphotic cable far away in the TD-SCDMA base station; Be convenient to install; And the weight of optical cable is added the weight of power lead greater than feeder line, will produce some problems if continue to use the construction method of GSM.
Especially pass the position of only shaft tower at optical cable and power lead, because gravity can make optical cable and power lead produce very big bending angle, and big bending angle like this can cause the damage of optical cable, and then influence the use of base station.The present invention then can solve these above problems.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of 3G (Third Generation) Moblie network TD-SCDMA base station only shaft tower BBU-RRU optical cable construction method, and this equipment construction method of installation is made up of following step:
The first step: the optical cable of unpacking;
Second step: make optical cable in order, carry out interim label;
The 3rd step: the A port (port that links to each other with RRU) to optical cable carries out necessary protection;
The 4th step: the curved line holder is installed;

Embodiment
Below in conjunction with Figure of description the invention is done further to specify.
Embodiment one
In the present embodiment one, the concrete steps of 3G (Third Generation) Moblie network TD-SCDMA base station only shaft tower BBU-RRU optical cable construction method are as shown in Figure 1, and its practical implementation step is:
The first step: the optical cable of unpacking;
Select the optical cable of appropriate length.Connect the BBU-RRU optical cable because of considering requirement to transmission quality; All be to adopt the fixed length optical cable; Whether the length of each required optical cable in base station is stipulated by design document, needs optical cable is checked as follows before therefore installing: 1. check the cable length that arrives the working-yard to conform to design document; 2. the presentation quality of check optical cable has the optical cable of appearance quality to forbid installing; 3. the quality of A, the B end connector part of inspection optical cable, an end that is used to connect RRU is called the A end, and an end that is used to connect BBU is the B end, and whether whether the inspection joint intact has attachment etc.;
Second step: make optical cable in order, carry out interim label;
Before laying optical cable, must make optical cable in order, prevent in the process of laying, to cause situation such as optical cable kink, knotting, winding, for the correct sector of distinguishing, must carry out interim label before the optical cable laying simultaneously;
The 3rd step: the A port (port that links to each other with RRU) to optical cable carries out necessary protection;
A port (port that links to each other with RRU) for the protection optical cable; Before the lifting optical cable; Need A port (port that links to each other with RRU) is carried out necessary protection; Salvo comprises uses firm cloth or grog paper bag to wrap up in A port (port that links to each other with RRU) etc., wants colligation firm after the requirement parcel is good;
The 4th step: the curved line holder is installed;
Line outlet place on tower, select suitable position to install and fix " curved line holder ", installation requirement: 1. curved line holder top is reserved enough spaces and is used for the optical cable cabling; 2. the arc mid point of curved line holder is the most better; 3. each securing member will be installed firmly; 4. when regulating the two ends stationary installation, need guarantee two ends stationary installation even regulation, to guarantee the two ends stress balance;
The 5th step: lifting optical cable;
Personnel will lift with rope and put down from the line outlet on the tower on the tower, and personnel pull out rope from the incoming line under the tower under the tower, and will be with rope that the A end colligation of optical cable is good.Personnel lift by crane optical cable on the tower, and personnel carry optical cable to line inlet port under the tower, and personnel use intercom to coordinate operation on the tower, under the tower, and synchronous operation requires lifting speed unsuitable too fast, and tower is harmonious up and down;
The 6th step: fixing optical cable;
On the tower personnel the optical cable of reserving sufficient length be used for being connected of RRU after, carry out colligation to optical cable and fix.Require: 1. optical cable is serious closely connected obeys on the arcwall face of curved line holder; 2. with the cavity of binding strap, optical cable is carried out colligation through the curved surfaces of " curved line holder "; 3. adjust " curved line holder " position in case of necessity, make to install to reach best effects;
The 7th step: optical cable is connected respectively with BBU, RRU.
According to construction method of the present invention, optical cable is connected with BBU, RRU respectively, wherein the A end connects RRU, and the B end connects BBU, and the good prior ready-made label of inspection has simultaneously been distinguished the BBU of three sectors, base station and the corresponding relation of RRU.
Wherein, between second step of implementation method of the present invention and the 3rd step, also comprise: 1. erecting optical cables disc carrier; 2. workmen Deng Ta on the tower.The reel unwrapping wire is provided with simple and easy reel support for ease, guarantees to lay optical cable and makes the stressed minimum of optical cable, can prevent also that simultaneously optical cable from placing when dragging on the ground and the friction on ground and stained optical cable.Carry the construction tools necessary when stepping on tower personnel Deng Ta, comprise that the lifting that lifts optical cable is with rope, intercom etc.
