Embodiment one：
Referring to FIG. 1, the present embodiment provides a kind of, communication device applied to underground parking, it is used for and remote serviceDevice is communicated, and has communication module group 1 and emitting mould train 2, the emitting mould train 2 includes antenna element and gain unit, describedAntenna element is connect with the communication module group 1；The antenna element sends out to emit communication signal and receive remote serverResponse signal, the communication module group 1 is generating communication signal and handle the response signal；The gain unit is removableIt is connected to the antenna element with unloading, to amplify the signal strength of the communication signal and the response signal.
When signal strength when communicate of the antenna element in underground parking is weak, gain unit can be to transmissionCommunication signal and the response signal of reception are enhanced, to solve communication device in underground parking to communicate to be that signal strength is weakThe problem of.
Further, in the present embodiment, the antenna element includes the first lid 24 and transmitter 21, the transmitter21 connect with the communication module group 1, and first lid 24 is hemisphere face structure, and first lid 24 is equipped with primary antenna electricityRoad and the first connector 23, the primary antenna circuit are connect with first connector 23, and first connector 23 runs through described firstLid 24, first connector 23 are connect towards 24 inner opposite end of the first lid with the transmitter 21, and described first connectsFirst 23 connect towards 24 lateral ends of the first lid with the gain unit.
The first hemispherical lid 24 can provide the area of bigger for primary antenna.It is also beneficial to primary antenna around simultaneouslySend and receive signal.When communication module group 1 generates communication signal, it can be transferred to primary antenna circuit by transmitter 21, by leadingAntenna circuit sends communication signal, while also receiving the response signal that server is passed back, and is transmitted by transmitter 21It is handled to communication module group 1.
The gain unit includes the second lid 25, and second lid 25 is hemisphere face structure；Second lid 25It is equipped with the gain antenna circuit and the second connector 26 to amplified signal intensity, the gain antenna circuit connects with described secondFirst 26 connection, second connector 26 run through second lid 25, the court of second lid 25 and first lid 24To identical, second connector 26 is connect with first connector 23.The gain unit is multiple, multiple gain listsMember is stacked, and is connected by second connector 26 between two neighboring gain unit.
Second lid 25 and the first lid 24 are the similar dome-type of shape, and when installation, the second lid 25 and first is coveredThe direction of body 24 is adjusted to same direction, and the second connector 26 and the first connector 23 are linked together, when the first lid 24 holdIt is contained in the inside of the second lid 25.Space is utilized to the greatest extent, reduces the volume of communication device.Meanwhile it can stop under base areaThe depth selection in parking lot adds different layers of gain units, and depth is deeper, and the gain unit number of plies added is more, to meet notWith the requirement of depth.When installing multi-layer gain unit, the direction of all second lids 25 can be adjusted to consistent, and will be adjacentThe second lid 25 connected by the second connector 26, so that multiple gain units is superimposed.When using multiple gain units,Controller 22 controls gain unit and antenna element by the way of antenna diversity, avoids interfering with each other.
When primary antenna is when sending communication signal, communication signal can give gain antenna electricity from 26 simultaneous transmission of the second connectorRoad, gain antenna circuit can enhance the signal strength for communicating model, and carry out the hair of communication signal together with primary antennaIt penetrates.When primary antenna receives response signal, gain antenna circuit receives to it response signal with primary antenna circuitIt carries out amplification and is transferred to primary antenna circuit, the response signal finally received with primary antenna circuit is transferred to communication module group1.With this, signal strength of the communication device when underground parking communicates can be enhanced, avoid influencing because signal strength is excessively weakCommunication.
Embodiment two：
Referring to FIG. 2, in the present embodiment, on the basis of embodiment one, the gain unit has multiple directional aerials27, multiple electronic switches 28 and controller 22 are corresponded with those directional aerials 27；It is right therewith that each directional aerial 27 passes throughThe electronic switch 28 answered is connected to controller 22, and the controller 22 controls each directional aerial 27 by controlling each electronic switch 28Working condition；Those directional aerials 27 are used for directive sending communication signal and directional reception response signal, and each directional aerial27 correspond to different directions.The signal strength for the response signal that the controller 22 can be received in directional aerial 27 is less thanIt controls the electronic switch 28 connecting with the directional aerial 27 when preset threshold intensity to close, the directional aerial 27 is set toOn second lid 25, and the directional aerial 27 is connect with second connector 26.
When communication device is communicated, controller 22 controls the response letter that multiple directional aerials 27 receive different directionsNumber, and detect the signal strength for the response signal that each directional aerial 27 receives.To the wherein maximum orientation day of signal strength27 corresponding electronic switch 28 of line is opened, and closes remaining 27 corresponding electronic switch 28 of directional aerial.Most using signal strengthStrong directional aerial 27 is communicated together with primary antenna circuit and gain antenna circuit, can targetedly enhance global communicationSignal strength, and ensure that the signal strength of communication on the direction corresponding to current directional aerial 27 is most strong.Meanwhile using fixed, can be in the case where power be certain to antenna 27, the signal strength on corresponding direction is most strong.Make in the case where reducing energy consumptionCommunication effect is best.
When gain unit is multiple, the setting of directional aerial 27 can be two kinds of situations between different gains unit：The firstSituation is that 27 corresponding direction of directional aerial is different between different gains unit.That is by the orientation day in different gains unitDirection corresponding to line 27 is staggered, and keeps the corresponding direction of all directional aerials 27 in multiple gain units different, in this way,It while increasing gain unit quantity, can also increase the quantity of corresponding direction, make communication device that can more accurately select mostGood direction of communication.
The second situation is that 27 quantity of directional aerial in multiple gain units is identical, and is oriented between different gains unit27 corresponding direction of antenna corresponds.That is the direction all same corresponding to the directional aerial 27 in each gain unit,So that 27 quantity of corresponding directional aerial on single direction is increased, so that signal strength in this direction is enhanced, further increase communicationEffect.
Certainly, when gain unit quantity is three or more, above two can also be crossed to situation according to actual demand phaseIn conjunction with, it is flexible and changeable with being arranged according to the demand of user for correspondence, it is adaptable.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this fieldFor technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made byModification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
