Description
Technical field
The present invention relates to a kind of manual electricity and adjust the antenna assembly of adjusting with far-end electric tuning.
Background technology
Along with the fast development of communications industry, operator and user improve constantly the requirement of network quality, the higher area of dense city and floor particularly, and optimizing and revising of network is more frequent, often need to adjust the electrical tilt of antenna for base station.Electrical tilt antenna can be adjusted the electrical tilt of antenna easily, at moving communicating field, is widely used.
The electrical tilt of electrical tilt antenna adopts phase shifter to adjust, and driven adjustable phase shifter to move or rotated, thereby the electrical length of change feeding network reaches the object of adjusting antenna electric inclination angle by mechanical device.The method that antenna electric inclination angle is adjusted has two kinds, and a kind of is that manually electricity is adjusted, and a kind of is that far-end electricity is adjusted.Manual electricity is adjusted has advantages of that cost is low, simple to operate, but each adjustment antenna electric inclination angle all needs to climb up pylon, operates.Far-end electricity adjust by antenna inside or outer setting motor the electrical tilt of antenna is adjusted.With respect to manual electricity, adjust, far-end electricity is adjusted and can be realized the adjustment to antenna electric inclination angle without climbing up pylon, has advantages of convenient adjustment.In order to realize far-end electricity, adjust, generally adopt RCU(Remote Control Unit, remote control unit) to being arranged on the phase shifter of antenna inside, control, thus realize the adjustment at antenna electric inclination angle.RCU divides two kinds of built-in and externals.External RCU is that the phase shifter drive mechanism by physical interface on antenna and antenna inside is connected, and controls electrical tilt antenna drive mechanism and rotates or translation, thereby drive phase shifter motion by RCU, realizes the object of Long-distance Control antenna electric degree of tilt.Built-in RCU is placed on antenna inside by RCU, without RCU is installed in addition, can make antenna support far-end electricity to adjust, and therefore in antenna of mobile communication base station, is widely used.
But, for the electrical tilt antenna that adopts built-in RCU, if built-in RCU, if there is fault, cannot adjust antenna electric inclination angle, for the antenna of going up station use, have to carry out antenna replacing.If electrical tilt antenna supports far-end electricity to adjust with manual electricity simultaneously, adjust, when RCU breaks down, row adjustment still can be transferred in by manual electricity in antenna electric inclination angle, does not affect the use of antenna.In addition, the occasion of adjusting at some inconvenient electricity manually electric tune also can provide greater flexibility for the use of antenna.
In order to make electrical tilt antenna support that manually electricity tune is adjusted with far-end electricity simultaneously, the manual electricity tune structure of antenna inside need to adjust structure coexist with far-end electricity.For traditional electrical tilt antenna, the electrical tilt information of antenna is stored in RCU inside, and when changed the electrical tilt of antenna by manual electric tune mode, system cannot know that electrical tilt changes, and therefore manually electricity is adjusted with far-end electricity tune and cannot be coordinated.
In order to adapt to the new demand of radio communication to antenna for base station, need a kind of manual electricity to adjust with far-end electricity and adjust the antenna for base station coexisting, and manually electricity tune can be coordinated mutually with far-end electricity tune, no matter manually electricity tune or far-end electricity tune can be to the correct information relevant to antenna electric inclination angle of system feedback.
