Accompanying drawing explanation
Fig. 1 is the circuit diagram of intelligent and safe switch controller.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of intelligent and safe switch controller，Including relay J、Metal-oxide-semiconductor Q1、Audion Q2、Resistance R1、Key switch S1 and electric capacity C1，Described electric capacity C1 one end ground connection，The electric capacity C1 other end connects relay J contact J-1 respectively、Resistance R1、The S pole of electric capacity C3 and metal-oxide-semiconductor Q1，The relay J contact J-1 other end connects power supply VCC，The resistance R1 other end connects the G pole of metal-oxide-semiconductor Q1 respectively、Resistance R2 and key switch S1，The key switch S1 other end connects ground capacity C2 and resistance R3 respectively，The resistance R3 other end connects the D pole of metal-oxide-semiconductor Q1 respectively、The electric capacity C3 other end、Resistance R4、Audion Q3 colelctor electrode and output end vo，Resistance R4 other end connecting triode Q3 base stage respectively、Resistance R5 and audion Q2 base stage，Audion Q2 colelctor electrode connects resistance R2，Audion Q2 emitter stage connects the resistance R5 other end and relay J coil ground connection respectively，Relay J coil other end connecting triode Q3 emitter stage；Described relay J contact J-1 is normally-closed contact.
Operation principle of the present utility model is: refer to Fig. 1, push button under original state switch S1, electric capacity C2 two ends are all low-voltage, and the G pole of Q1 is also low, and Q1 turns on, through R4 and R5 dividing potential drop, make Q2 turn on, electric current through R1, R2 and Q2 to ground so that the G electrode potential of Q1 is more extremely low than S, Q1 constant conduction, exports DC voltage from output end vo；Again pressing S1, C2 through R2 and Q2 electric discharge until the base voltage deficiency of Q1 is so that Q2 conducting, the G pole of Q1 uprises, and Q1 turns off, and output end vo stops output.
Audion Q3, resistance R4, resistance R5 and relay J also form an overvoltage crowbar, and when the voltage of resistance R4 and R5 sampling exceedes setting value, audion Q3 turns on, relay J adhesive, and its contact J-1 disconnects, thus the VCC that cuts off the electricity supply.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
