Automatically control, reduce the resource occupation of system, be a critically important key point, in view of it is mentioned above the problem of, this practicality is new
Type designs a kind of device of automatic signal reiving/transmitting state switching, mentioned above to solve the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of device of automatic signal reiving/transmitting state switching, to solve above-mentioned background
The problem of device of the automatic signal reiving/transmitting state switching proposed in technology.
To achieve the above object, the utility model provides following technical scheme：A kind of automatic signal reiving/transmitting state switching
Device, including automatic control module, power amplifier module and electronic switch, electrically output connects power amplifier to the automatic control module respectively
Module and electronic switch, the power amplifier module electrically export connection electronic switch by transmitting chain, and the electronic switch passes through
Transmitting chain is electrically bi-directionally connected antenna, and the electronic switch is connected with receives link.
Preferably, the automatic control module includes wave detector and comparator.
Preferably, the electronic switch includes transmitting-receiving switching interface.
Compared with prior art, the beneficial effects of the utility model are：The device of this kind of automatic signal reiving/transmitting state switching,
The amplitude exported according to transmission signal, is opened or closed, and control electronic switch automatic to automatically control the power amplifier module of rear class
The switching of signal transmitting and receiving state, reaches the function of system automatic signal reiving/transmitting state switching, and the utility model is based on transmission signal
The amplitude detection of output, the switching of automatic realizing system signal transmitting and receiving state, structure and circuit are simple, easy to use, reduce
The control that system switches to signal transmitting and receiving state.
Brief description of the drawings
Fig. 1 is system block diagram of the present utility model；
Fig. 2 is the block diagram of automatic control module of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of dress of automatic signal reiving/transmitting state switching
Put, including automatic control module, power amplifier module and electronic switch, electrically output connects power amplifier mould to the automatic control module respectively
Block and electronic switch, the power amplifier module electrically export connection electronic switch by transmitting chain, and the electronic switch passes through hair
Penetrate link and be electrically bi-directionally connected antenna, the electronic switch is connected with receives link.
Wherein, the automatic control module includes wave detector and comparator, and the electronic switch includes transmitting-receiving switching interface.
Operation principle：The amplitude size of the transmission signal that automatic control module exports according to signal processing module is controlled automatically
The switching control of the reiving/transmitting state of system processed, power amplifier module are used to the transmission signal of signal processing module being amplified to transmitting work(
Rate, after electronic switch being output to antenna launches, and system transmitting-receiving is completed in the control of electronic switch module under automated control
The switching of state, in system transmitting chain be signal processing module after power amplifier module, electronic switch, by transmission signal through antenna
It is transmitted into the air, receives link refers to that aerial signal enters signal processing module, tdd systems by electronic switch
Refer to can only to have at any time receives link or transmitting chain work, reiving/transmitting state switching therein by automatic control module Lai
Control electronic switch does link switching, and wave detector is used for transmission signal detection into direct current signal, the direct current signal and with reference to letter
Number it is compared in a comparator, if direct current signal is more than reference signal, output control signal, control electronic switch enters
Signal emission state, if direct current signal is less than reference signal, output control signal, electronic switch are not maintained at signal reception
State.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
