Compared with prior art, the beneficial effects of the utility model are: DX transmitter radio-frequency (RF) switch failure detector of the present utility model can detecting transmitter while, by radio-frequency (RF) switch control panel, the ruuning situation of emission control switch and parts are detected effectively, reduce the probability that transmitter breaks down, reduce the operating cost of transmitter, obtain good economic benefit.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the circuit diagram of an embodiment of DX transmitter radio-frequency (RF) switch failure detector of the present utility model.
Embodiment
Below in conjunction with each embodiment shown in the drawings, the utility model is described in detail; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection domain of the present utility model.
As shown in Figure 1, DX transmitter radio-frequency (RF) switch failure detector 100 of the present utility model comprises: power pack 10, first gauge tap 20 and the second gauge tap 30.
Wherein, described first gauge tap 20 and second gauge tap 30 one end and described power pack 10 are electrically connected, and the pin of the other end and radio-frequency (RF) switch control panel is electrically connected.
Particularly, described first gauge tap 20 is electrically connected with the positive terminal of described power pack 10, and the input end of the other end and described radio-frequency (RF) switch control panel 200 is electrically connected.This first gauge tap 20 is for controlling opening and closedown of described power pack 10, namely when the first gauge tap 20 closes, power pack 10 is in opening state, when transmitter is in outage detection state, power pack 10 provides electric energy for radio-frequency (RF) switch, detects under being convenient to its power on condition.
Described second gauge tap 30 is electrically connected with the negative pole end of described power pack 10, and three pins on the other end and described radio-frequency (RF) switch control panel 200 carry out selectivity electric connection.This second gauge tap 30 is for controlling the rotating forward of radio-frequency (RF) switch, reversion and stopping.Correspondingly, three pins on described radio-frequency (RF) switch control panel 200 are the corresponding circuit structure controlling radio-frequency (RF) switch and rotate forward, reverse and stop respectively, when the second gauge tap 30 is electrically connected to different pins, corresponding circuit structure is in connected state, and radio-frequency (RF) switch forwards and reverses or stops.
