Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of model airplane remote controller antenna condition detection system, comprise an electric bridge directional couple unit 2, described electric bridge directional couple unit 2 is placed between transmission final stage amplifier 1 and antenna system, in order to the transmitted wave inputted from transmission final stage amplifier 1 is outputted to antenna system, and export the transmitted wave of transmission final stage amplifier 1 input and the reflection wave of antenna system generation at output port A and output port B respectively; One group of wave detector, comprise wave detector A 5 and wave detector B 6, wave detector A 5 and wave detector B 6 connects one to one with the output port A of described electric bridge directional couple unit 2 and output port B respectively, in order to detect the magnitude of voltage of transmitted wave that transmission final stage amplifier 1 inputs and the reflection wave that antenna system produces; And a control circuit 7, control circuit 7 tie geophone A 5 and wave detector B 6, and receive their output signal, in order to judge the state of antenna system by processing the testing result received, in control circuit 7, the detecting circuit of wave detector A 5 and wave detector B 6 is carried out amplify, superpose and on average, the impact of reflected voltage can be avoided.In control circuit 7, simulating signal is converted to digital signal and to go forward side by side line number word processing.On the other hand, comparer or similar period also can be adopted to form this control circuit in an analog fashion; Described antenna system is made up of antenna 3 and antenna connector 4, and antenna 3 is connected to electric bridge directional couple unit 2 by antenna connector 4, and the output signal of transmission final stage amplifier 1 is transferred to antenna 3 from electric bridge directional couple unit 2 through antenna connector 4 terminal.
