Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Fig. 1 is the schematic block diagram for showing detection means 100 according to embodiments of the present invention.Detection means 100 is connected between antenna opening and feeder line.
As shown in figure 1, detection means 100 includes detection module 110, control module 115 and transport module 120.Detection module 110 is coupled to antenna opening, for detecting antenna opening power.Detection module 110 generates detection information according to the antenna opening power detected.Control module 115 is used to detection information being converted to transmission signal, and transport module 120 is used to send the transmission signal.
So, the detection means of the embodiment of the present invention directly detects antenna opening power, and send out the information of antenna opening power by being coupled to the detection module of antenna opening.It is possible thereby to the power of remote detection antenna opening, so that the transmission state of more convenient monitoring antenna and corresponding feeder line exactly.
In addition, during the network planning is implemented, because feeder line is different in size, existing scheme can only field measurement feed line length, then feeder loss is gone out by theoretical calculation.This process workload is larger, equally consumes substantial amounts of human cost, has also dragged slowly the time of the network planning.
And it is according to embodiments of the present invention, when implementing the network planning, the feeder loss that can also be arrived using remote detection, accurate adjustment base station mouthful transmission power.Antenna top ports EIRP (effective isotropic emission power is accurately calculated by the feeder loss detected；Effective Isotropic Radiated Power), accurately carry out the network coverage.
Detection means shown in Fig. 1 is connected between antenna opening and feeder line, specifically, and detection means can be located at inner antenna, can also be located at outside antenna（For example between antenna and feeder line）.Fig. 2 depicts one embodiment that detection means is located between antenna and feeder line.Fig. 2 is the schematic configuration diagram for showing communication system 200 according to an embodiment of the invention.
As shown in Fig. 2 communication system 200 includes antenna 210, detection means 220, feeder line 230 and base station master device 240.Detection means 220 is located between antenna 210 and the antenna side of feeder line 230, and the other end of feeder line 230 is connected to base station master device 240.
Detection means 220 includes detection module 222, control module 223 and transport module 224, is analogous respectively to detection module 110, control module 115 and transport module 120 shown in Fig. 1.
Specifically, detection module 222 can detect antenna opening power, and generate detection information according to the antenna opening power detected with direct-coupling antenna opening.For example, can be by for detecting that the coupler of power realizes detection module 222.
The detection information that detection module 222 is generated is converted to OOK (binary system on off keyings by control module 223；On-Off Keying) signal, and by transport module 120 by the OOK signals via feeder line
230 are sent to base station master device 240.
Base station master device 240 receives the transmission signal sent from detection means 220, and the acquisition antenna opening power from the transmission signal.In addition, base station master device 240 according to existing method, can also detect the base station side of base station mouthful power, i.e. feeder line 230（The interface that base station master device 240 is connected with feeder line 230) on power.So as to which base station master device 240 can be according to antenna opening power and base station mouthful power calculation feeder loss, and judge whether feeder line is faulty according to feeder loss.
If for example, base station mouthful power is 20w, and the antenna opening power measured is 5w, then feeder loss is 20w-5w=15w, significantly larger than general feeder line should be lossy, then may determine that feeder line breaks down.
On the other hand, if base station mouthful power is 20w, and the antenna opening power measured is 18w, then presents
Line loss consumption is 20w-18w=2w, in the range of permissible feeder loss, then may determine that feeder line does not have failure.If now antenna-feedback system still breaks down, it may determine that antenna part breaks down.Permissible feeder loss scope can be not limited to specific example numerical value given here according to actual needs or the factor such as performance of feeder line is determined.
Therefore, communication system 200 according to embodiments of the present invention can not only monitor the transmission state of antenna-feedback system, can also quickly find the abort situation of antenna-feedback system, so as to improve maintenance speed, save cost, facilitate system maintenance.Meanwhile, when implementing the network planning, the feeder loss that can also be arrived using remote detection, accurate adjustment base station mouthful transmission power.Antenna top ports EIRP is accurately calculated by the feeder loss detected, the network coverage is accurately carried out.
Fig. 3 depicts one embodiment that detection means is located at inner antenna.Fig. 3 is the schematic configuration diagram for showing communication system 300 according to another embodiment of the present invention.
As shown in figure 3, communication system 300 includes antenna 310, feeder line 330 and base station master device 340.Feeder line 330 is connected between antenna 310 and base station master device 340.
Detection means 320 is located inside antenna 310, and is connected to the antenna side of feeder line 230.Detection means 320 includes detection module 322, control module 323 and transport module 324, is analogous respectively to detection module 110, control module 115 and transport module 120 shown in Fig. 1.
Specifically, detection module 322 can detect antenna opening power, and generate detection information according to the antenna opening power detected with direct-coupling antenna opening.
Further, since during the transmission state of detection antenna-feedback system, standing wave is also the parameter often paid close attention to.Therefore, detection module 322 detects circuit 3225 comprising internal standing wave, can obtain antenna opening standing wave from the antenna opening power detected.Standing wave detection circuit 3225 can extract corresponding standing wave information according to the power positive and negative values detected.Now, in the detection information that detection module 322 is generated, in addition to the information of antenna opening power, the information on antenna opening standing wave can also be included.
Transport module 324 and Fig. 2 transport module 224 is different.Transport module 324 utilizes wireless transmission method.
Specifically, detection information is converted to wireless signal by control module 323, then passes through radio channel by transport module 324（As shown in the dotted arrow in Fig. 3）The wireless signal is sent to base station master device 340.For example, WiFi (Wireless Fidelity can be passed through;Wireless Fidelity）Module realizes transport module 324.
So, even if feeder line can not work completely, the state of antenna opening power/standing wave also can be wirelessly sent to the base station master device on ground, it is ensured that the successful of monitoring.Meanwhile, base station master device 340
Also the information that can be provided according to detection means 320, determines the abort situation of antenna-feedback system.For example, it is assumed that base station mouthful power is 20w, and the antenna opening power measured is 0w or other significantly lower performance numbers（Such as 2w）, then base station master device can determine that at least feeding line portion occurs in that failure.
Multiple embodiments of the present invention are described above is, but the scope of the present invention is not limited to these specific embodiments.The element in not be the same as Example can be combined, for example, Fig. 2 detection means can also merge Fig. 3 internal standing wave detection circuit 3225.
In addition, although Fig. 2 and Fig. 3 depict detection means includes the embodiment of wired and wireless transmission method respectively, but detection means according to embodiments of the present invention can also include the mode of wired and wireless two kinds of transmission detection information simultaneously, i.e. detection means can include control module 223, transport module 224, control module 323 and transport module 324 simultaneously.In the case, detection means according to embodiments of the present invention concurrently can send detection information by feeder line and radio channel to base station master device respectively, can also come to send detection information to base station master device optionally through one of feeder line and radio channel.For example, in the case where feeder line can not work completely, detection means also can send detection information by radio channel, it is ensured that base station master device obtains antenna and the transmission state of respective feed connection.Such embodiment is within the scope of the present invention.
Other changes can also be carried out to above-described embodiment within the scope of the invention.For example, Fig. 2 detection means 220 can also be located inside antenna 210；Fig. 3 detection means 320 can also be located at outside antenna 310, i.e., between antenna 310 and feeder line 330.
In some cases, base station master device can not detect base station mouthful power, you can determine abort situation.Example as explained above, when antenna-feedback system breaks down and antenna opening power is Ow or other significantly lower values, can directly determine that feeding line portion occurs in that failure, without detection base station mouthful power.
