Abstract

The invention relates to an automatic isolation performance detection processing method, comprising the following steps of: 1) judging whether an automatic attenuation value system is started, if not, deactivating an automatic attenuation value, recovering the setting of a manual attenuation value, if so, storing the manual attenuation value, deactivating the manual attenuation value, and initializing, wherein a downlink attenuation value = 0 dB, an uplink attenuation value = 5 dB; 2) judging whether an initial control depth is more than 1 dB, if so, executing step 3), if not, executing step 4); 3) judging whether the initial control depth is not more than (26dB uplink attenuation value), if so, respectively deducting 1 dB from the uplink attenuation value and the downlink attenuation value, if not, increasing 1 db attenuation on the basis of an original start numerical control attenuation to obtain the downlink attenuation value equal to 26 dB and the uplink attenuation value equal to 31 dB at most. In comparison with the prior art, the method has the advantages of reducing operation and maintenance cost, processing problems in time, adding an isolation performance warning function, and the like.

Description

A kind of isolation detects processing method automatically

Technical field

The present invention relates to a kind of base station and detect and processing method, especially relate to a kind of isolation and detect processing method automatically.

Background technology

The repeater is a part important in the mobile communication system; its stabilization of equipment performance directly has influence on whole communication system; develop rapidly in the current communications industry; requirement to the repeater is also more and more higher; the major function of repeater is to finish relaying; the signal that reception is come amplifies; if in application process because of the engineering design problem; or environmental change will make repeater equipment self-excitation phenomena may occur because of the problem of isolation; in case producing self-excitation equipment itself can not normally or damage; may have influence on the base station when serious; make the communication in the whole base station range can't operate as normal; when this class situation occurring generally is that the project installation personnel of specialty solve with checkout equipment or keep having between retransmitting antenna and the donor antenna enough distances to guarantee that isolation is enough big between dual-mode antenna always; all there is the increase manpower in above-mentioned dual mode; reaction speed when safeguarding, or because of problems such as geographical position and installation costs.

Summary of the invention

Purpose of the present invention is exactly to provide a kind of in order to overcome the defective that above-mentioned prior art exists and reduce O﹠M cost, handle problems in time, also increase the isolation of isolating warning function and detect processing method automatically.

Purpose of the present invention can be achieved through the following technical solutions:

A kind of isolation detects processing method automatically, it is characterized in that, this method may further comprise the steps:

1) judge whether automatic pad value system opens, if not, pad value lost efficacy automatically, replied manual pad value setting, if yes, preserved manual pad value, and manually pad value lost efficacy, and initialization: down link pad value=0dB, up link pad value=5dB;

2) whether judgement starts to control the degree of depth greater than 1dB, if yes, and execution in step 3), if not, then execution in step 4);

3) whether judgement starts to control the degree of depth smaller or equal to (26-line link pad value), if yes, then up pad value, downstream attenuation value respectively subtract 1dB, if not, on original basis, increase the 1dB decay with starting the numerical control decay, be up to down link pad value=26dB, up link pad value=31dB;

4) single-chip microcomputer reads power output and concerns and whether judge power output less than specified output with rated output power, if the judgment is No execution in step 5 then), execution in step 7 then if the judgment is Yes);

5) whether judge the down link pad value greater than 26dB, will start the numerical control decay if the judgment is Yes and on original basis, increase the 1dB decay, be up to down link pad value=26dB, up link pad value=31dB; Execution in step 6 then if the judgment is No);

6) judge whether start to control the degree of depth equals 0, up-downgoing decay interlock then if the judgment is Yes, up pad value, downstream attenuation value respectively increase 1dB; Up-downgoing decay interlock then if the judgment is No, up pad value, the downstream attenuation value 1dB that respectively decays;

7) judge whether start to control the degree of depth equals 0, then continue if the judgment is Yes whether to judge power output, if the judgment is Yes execution in step 8 then) less than rated output power;

8) judge whether power output becomes greatly, and if the judgment is No, then execution in step 9), execution in step 10 then if the judgment is Yes);

9) judge whether power output diminishes, up-downgoing decay interlock then if the judgment is No, up pad value, the downstream attenuation value 1dB that respectively decays; Execution in step 10 then if the judgment is Yes);

10) judge that whether the down link pad value is greater than 0, up-downgoing decay interlock then if the judgment is Yes, up pad value, downstream attenuation value respectively increase 1dB, then will start the numerical control decay if the judgment is No and on original basis, increase the 1dB decay, be up to down link pad value=0dB, up link pad value=5dB.

Compared with prior art, the present invention has the following advantages:

1, can avoid in engineering is used, damaging the repeater, can also reduce O﹠M cost because of isolator is defective.

Find when 2, anxious and automatically terminate the isolation problem, avoided negative effect that communication system is brought, increase customer satisfaction degree.

3, increase the isolation alarm function in the equipment, make that design is humanized.
