Detailed description of the invention
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments:
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
As shown in Figure 1, the present invention relates to a kind of antenna beam directions to adjust system and method, wherein antenna beam direction Adjustment system includes transmitting station 110 and wave detector 120.
Transmitting station 110 is equipped with antenna 111 and phase controller 130 for launching beam, in the present embodiment, day Line 111 uses array antenna.
Specifically, transmitting station 110 can also have more, can also have mutiple antennas 111 on every transmitting station 110.
Wave detector 120 is set to wave beam receiving end, is wirelessly connected with transmitting station 110, the wave emitted for receiving antenna 111 Beam.
Phase controller 130 and wave detector 120 are wirelessly connected comprising to operation beam phase microprocessor and The phase shifter of beam phase can be controlled according to the operation result of microprocessor, phase shifter being capable of output voltage control signal pair The beam phase of antenna is controlled.
In the present embodiment, transmitting station 3 is Ethernet base station, and phase controller 130 is connected with serial data device 150, Wave detector 120 and serial data device 150 are wirelessly connected, and signal is transferred to serial data device 150 by Ethernet by wave detector 120, And the serial data device 150 can convert a signal into phase controller 130 again being capable of received signal.
Specifically, transmitting station 110 uses WIFI radio base station, and serial data device 150 uses nport5150, in order to make to go here and there Array apparatus 150 can receive the signal transmitted by Ethernet, it is necessary to nport5150 connect at the end LAN of transmitting station 110, Therefore it becomes local area network a part that 110 frameworks of the transmitting station go out, and outer net is to can't see nport5150, so will be to it It gives an order, it is necessary to which then a port is opened to nport5150 in the end WAN for first connecting the transmitting station.
And the above-mentioned nport5150 used is only one of facilities and equipments, it is any that network signal can be allowed to control phase Position can all use to the trunking of control circuit for the serial data device 150.
Method of adjustment of the invention is as follows:

Two, multiple wave beams are received by wave detector 120, and records sequential encoding when each wave beam receives, wave detector 120 Face presets a preset phase in the removable phase range of wave beam.
Certainly before reception, the two need to be established in the IP address and port value of the input transmitting station 110 of wave detector 120 TCP line.
Three, comparative analysis goes out signal most high-amplitude wave beam, sends the sequential encoding to induction signal most high-amplitude wave beam by wave detector 120 To phase controller 130.
Wherein it is possible to go out signal most high-amplitude wave beam by 120 comparative analysis of wave detector.
Certainly, the signal strength of multiple wave beams is sent to cloud platform 140 also by wave detector 120, is put down by the cloud 140 comparative analysis of platform goes out signal most high-amplitude wave beam, and sends result to wave detector 120, and cloud platform 140 and wave detector 120 connect It connects.
Four, according to the sequential encoding of signal most high-amplitude wave beam, by phase controller 130 by the phase tune of signal most high-amplitude wave beam Whole is preset phase, and the most strong beam direction of signal is made to be directed toward wave detector.
Wave detector is arranged in wave beam receiving end the present invention, and the wave beam of antenna transmitting is detected by wave detector, according to wave beam Signal strength is adjusted beam phase by phase controller, realizes that signal most high-amplitude wave beam can be directed toward the position of wave detector, It is directed toward wave beam receiving end and improves communication quality so as to effectively promote the transmitting-receiving ability of radio base station.
Wave beam is moved phase range and is set in ± 60 ° by the present embodiment, by every 5 ° of wave beams, passes through transmitting station 110 Emit 25 wave beams, ° successively launching beam from+60 ° to -60, then the sequential encoding of+60 ° of wave beams is 1, the sequence of -60 ° of wave beams The sequential encoding for being encoded to 25,0 ° of wave beam is 13, when 120+30 ° of face preset phase of wave detector, if signal most high-amplitude wave beam be+ Corresponding sequential encoding 7 is then sent to phase controller 130 by 60 ° of wave beams, and phase controller 130 is by the phase of respective beam + 30 ° are adjusted to, i.e., most strong beam position wave detector 120.
It is same that the wave that each antenna 111 emits is received by wave detector 120 when having mutiple antennas 111 on transmitting station 110 Beam, finds out the signal most high-amplitude wave beam of corresponding each antenna 111, and passes through phase controller 130 for the most strong beam position of each signal Wave detector 120.
When transmitting station 110 is multiple, the position of different transmitting stations 110 is also different, therefore the transmitting station 110 of different location Be respectively connected with phase control unit 130, the wave detector 120 receive different location transmitting station 3 emit wave beam, due to data compared with Greatly, generally by beam signal strength material upload to cloud platform 140, to be compared and analyzed out each by cloud platform 140 Each corresponding signal of antenna most high-amplitude wave beam, is back to wave detector 120 for the result after comparative analysis, finally leads on transmitting station 110 Phase controller 130 is crossed by the most strong beam position wave detector 120 of each signal.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this Invention, and be not used as limitation of the invention, as long as in spirit of the invention, to embodiment described above Variation, modification will all fall within the scope of claims of the present invention.
