Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the utility model comprises resistance R 1, resistance R 2, resistance R 3, resistance R 4, triode T1, triode T2, wireless signal, switching on and shutting down signal and on/off circuit, triode T1 wherein is NPN type triode, triode T2 wherein is the positive-negative-positive triode, and resistance R 2 wherein is 75 kilo-ohms.The wireless signal of the present embodiment, resistance R 1, triode T1, resistance R 3 and triode T2 connect successively.The resistance R 2 of the present embodiment and triode T1 are in parallel, the equal ground connection of emitter E of resistance R 2 and triode T1.The collector electrode C of triode T1 is connected basis set B and all is connected with resistance R 3 with triode T2.The resistance R 4 of the present embodiment and triode T2 are in parallel; The emitter E of described triode T2 is connected with the switching on and shutting down signal, and the collector electrode C of triode T2 is connected with on/off circuit.
In the situation that there is not wireless signal (wireless signal is low level), the base stage of NPN triode T1 by resistance R 2 drop-down be low level, the collector electrode of T1 and emitter-base bandgap grading turn-off.This moment, the base stage of PNP triode T2 was drawn on the resistance R 4, and very little with the high voltage pressure reduction of switching on and shutting down signal, collector electrode and the emitter-base bandgap grading of T2 also are turned off, and the switching on and shutting down signal can't be connected to on/off circuit.
In the effective situation of wireless signal (wireless signal is high level〉1.5V), the pressure reduction VBE of the base stage of T1 and emitter-base bandgap grading〉and 0.7V, the collector electrode of T1 and emitter-base bandgap grading conducting, collector voltage is pulled to ground voltage 0V.The collector voltage of T1 equals the base voltage of T2, after it is pulled down to 0V, and the VBE of PNP pipe T2〉0.7V, the also conducting of T2, namely the switching on and shutting down signal is communicated with on/off circuit.
Just can realize this utility model as mentioned above.
