Description

A kind of antenna feeder standing wave based on RFID technique is than qualitative monitoring method
" technical field "
The present invention relates to the detection method of radio communication device, more particularly to a kind of antenna feeder standing wave based on RFID technique Than qualitative monitoring method.
" background technology "
The monitoring of the passive part of mobile communication indoor distribution system is substantially at blank before 2009.In recent years, market On occur in that a little monitoring product successively, but it is not always very smooth to suffer from relatively costly popularization.Released by the applicant at present The new monitoring product based on Micro RF ID i probes, with low cost and dependable performance, its principle is:By in room divided antenna Upper stickup Micro RF ID i probes, share original mobile communication room point passive network (without rewiring) is carried out to room subsystem Conduct monitoring at all levels.The purposes and beneficial effect of the new technology be:Movement, telecommunications, UNICOM, the room substation of the big operator of steel tower four Site monitoring system, without repeated construction, cost performance is high.But the technology there is also shortcoming:There is no antenna feeder standing wave than monitoring work( Can, and standing-wave ratio monitoring is exactly required for client's emphasis.
" content of the invention "
The present invention aims to provide a kind of antenna feeder standing wave based on RFID technique than qualitative monitoring method, based at present most The monitoring system of new Micro RF ID i probes, realizes function of the antenna feeder standing wave than qualitative monitoring, and to monitoring system other Performance do not produce any negative effect.The present invention is realized by following technical scheme:
A kind of antenna feeder standing wave based on RFID technique includes than qualitative monitoring method, the antenna feeder monitoring system being based on If RFID main frames, network management center, repeater/base station, multiplefrequency mixer, room subnetwork, dry aerial, some i probes and intelligence are eventually End;The multiplefrequency mixer is connected with RFID main frames and repeater/base station respectively;The network management center passes through nothing in RFID main frames Line communication mode is connected;The antenna is connected by room subnetwork with multiplefrequency mixer;Contain No. ID in some i probes, No. ID in each i probe is different, if some i probes are correspondingly arranged on dry aerial;The intelligent terminal detects i probes And be connected with network management center by communication;
It is characterized in that:Described antenna feeder standing wave includes than qualitative monitoring method:
The alarming threshold of standing-wave ratio is set to the antenna feeder monitoring system;
The antenna feeder monitoring system is monitored by RFID technique to antenna feeder tip down output power;
When the detection of a certain i probes in monitoring system occurs abnormal, system is judged, analysis occurs abnormal Reason;
The antenna feeder monitoring system judges have none i probe to detect normally, if lower of same main line under same main line Have the monitoring of other i probe for it is normal when, then can under the qualitative main line all detections exception for the tip standing-wave ratio it is different Often;It is that the main line for connecting the tip exception occurs if all i probes are detected during for exception under same main line;
When the antenna feeder monitoring system judges the abnormal exception for standing-wave ratio, judgement terminates and submits exception reporting to;If being When system judges the abnormal exception for main line, system jumps to main failure monitoring program.
Further, it is 10 standing-wave ratio alarm thresholding to be set to the antenna feeder monitoring system.
Further, the antenna feeder monitoring system excludes algorithm and carries out judging fixed by network failure topology.
The present invention based on RFID technique realize to antenna feeder standing wave than qualitative monitoring function, only need to be in original i probes system On the basis of system directly upgrading host software be to be capable of achieving, and i probes can sensitive paper matter trade mark be equally attached on antenna, extremely just Just, each i probe interior includes the positional information of respective antenna, it can be ensured that accurate, the timely positioning of failure.The present invention has Cost performance is high, easy construction, the accurate beneficial effect of fault location.
" brief description of the drawings "
Fig. 1 is the theory diagram of the antenna feeder monitoring system of the embodiment of the present invention.
Fig. 2 is the antenna feeder standing wave of the embodiment of the present invention than monitoring flow chart.
Fig. 3 is the mapping table of the standing-wave ratio, return loss and insertion loss of the embodiment of the present invention.
" specific embodiment "
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings:
As shown in figure 1, the theory diagram of antenna feeder monitoring system, including antenna feeder monitoring system RFID main frames, webmaster Center, repeater base station, multiplefrequency mixer, room subnetwork, antenna and i probes, multiplefrequency mixer respectively with RFID main frames, webmaster Center and repeater base station are connected, and antenna is connected by room subnetwork with multiplefrequency mixer, and i probes are arranged on antenna.
With reference to shown in Fig. 2 and Fig. 3, i probe systems are realized to antenna feeder tip down output power by RFID technique Monitoring, the reachable ± 2dB of accuracy value;Contrast standing-wave ratio and the corresponding relation between down output power Insertion Loss, return loss, refer to figure 3, as seen in Figure 3, when standing-wave ratio≤4.0 of antenna feeder tip, Insertion Loss value of the down output power in inner antenna < 2.0dB, the value cannot be recognized correctly in the accuracy rating of i probes;But when standing-wave ratio >=4.5 of antenna feeder tip When, in the Insertion Loss value > 2.0dB of inner antenna, the value, therefore can outside the accuracy rating of i probes for down output power Correctly to recognize;In view of under actual conditions, once there is standing-wave ratio exception in antenna feeder tip, and its value can be fast after more than 2.0 Speed becomes big, until 25.5;And also to ensure the accuracy of monitoring, it is left that standing-wave ratio alarm thresholding is arranged on 10 by this example The right side, Insertion Loss value now has changed into 5dB or so, can be i probe accurate measurements.
Although now i probes accurately detect Insertion Loss value and increased 5dB, still can not be qualitative for antenna feeder tip goes out Standing-wave ratio abnormality alarming is showed, as it is possible that being that main line part before tip occurs in that exception and causes the Insertion Loss value to increase. In order to evade above mentioned problem, antenna feeder monitoring system excludes algorithm and carries out qualitative, i.e., a certain i probes spy by network failure topology When measuring abnormal, as long as while have under same main line the monitoring of other i probe for it is normal when, then can own under the qualitative main line Detection exception is the tip standing-wave ratio exception;As having tetra- i probes of A, B, C, D under a certain main line, when occurring one under the main line When individual or multiple abnormal (A or ABC exceptions), as long as there is one or normal (D is normal), then can be qualitative for A or ABC is the end Tip standing-wave ratio exception.When all i probes monitorings are for exception under same main line, when system judges the abnormal exception for main line, and it is System jumps to main failure monitoring program.
Above example is only that fully disclosure is not intended to limit the present invention, all based on creation purport of the invention, without creation Property work equivalence techniques feature replacement, should be considered as the application exposure scope.
