Description of drawings

In order to be illustrated more clearly in the technical scheme of the utility model embodiment, to do to introduce simply to the accompanying drawing of required use among the embodiment below, apparently, accompanying drawing in describing below is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structure principle chart of the intelligent switch that provides of the utility model one embodiment;

Fig. 2 is the structure principle chart of the intelligent switch that provides of another embodiment of the utility model.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 1 shows the structure principle chart of the intelligent switch that the utility model one embodiment provides.This figure is the structural representation of the intelligent switch of wired inductive transfer, and this intelligent switch comprises current transformer TA, rectifier bridge B, triode Q and relay K; Wherein, current transformer TA is the core-theaded type current transformer, the magnetic conduction iron ring of current transformer TA (being called iron core again) M is used for passing the power lead L of televisor, the two ends of secondary induction coil (being called secondary coil or the secondary coil again) S of electric current mutual inductance TA device connect two ac input ends of rectifier bridge B respectively, the dc output end of rectifier bridge B connects the base stage of triode Q, another dc output end of rectifier bridge B connects the emitter of triode Q, the first input end of the collector connection relay K of triode Q, second input end of relay K is by the 5V direct supply in the divider resistance R junctor top box 1, the emitter Q ground connection of triode, relay K is arranged in the set-top box 1 of televisor, is used for the on off state of controller top box 1.

The concrete principle of the intelligent switch of wired inductive transfer shown in Figure 1 is as follows: the magnetic conduction iron ring M that before using the power lead L of televisor is passed current transformer TA, when televisor is opened, TV set power lead L becomes the former limit of current transformer TA, alternating current (220V among the TV set power lead L, the electromagnetic field that 50HZ) changes, the electromagnetic field of this variation passes to the secondary that secondary induction coil S(is current transformer TA by the magnetic conduction iron ring M of current transformer TA), the secondary induction coil S of current transformer TA produces alternating current, after rectifier bridge B rectification, become direct current, thereby drive triode Q conducting, make the closing of contact of relay K after the triode Q conducting, thereby open the switch of set-top box; When televisor shut down, the electric current among the power lead L of televisor diminished, and induced field disappears, the secondary induction coil S of current transformer TA does not then have electric current to produce, therefore triode Q does not have conducting, and relay K is in normally open, and 1 of set-top box realizes shutdown synchronously.
