Description
Technical field
The utility model relates to a kind of electric control appliance, particularly a kind of power control unit.
Background technology
At present, power control unit is arranged and often occurs theft problem, stranger's accidental operation can touch the button that can not start, cause maloperation, and then cause power control unit to run the program that should not run, affect the security of operation of electric system, reduce the security of power control unit.
Utility model content
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of power control unit, and structure simple designs is reasonable, improves work efficiency, effectively realizes warning function.
Its technical scheme is: comprise display, cabinet, wave filter, interface board, alarm, air switch and gauge tap, cabinet connects display, described display connecting interface plate, cabinet is provided with gauge tap, described gauge tap connects the alarm of cabinet inside, the inside of described cabinet connects air switch by wave filter, described alarm comprises power supply, switch S B, triode VT1, triode VT2, triode VT3, swept resistance RP, first resistance R1, second resistance R2, integrated circuit, light emitting diode, sensing chip, loudspeaker, power supply is by switch S B connecting triode VT1 successively, first resistance R1, triode VT2, integrated circuit and triode VT3, the base stage of described triode VT1 connects sensing chip, triode VT2 connects the 2nd pin input end of integrated circuit, 3rd pin output terminal connecting triode VT3 of integrated circuit, connecting luminous diode and loudspeaker on the collector of triode VT3.
The two ends swept resistance RP in parallel of above-mentioned triode VT1.
Second resistance R2 in parallel between 7th pin of above-mentioned integrated circuit and the 8th pin.
Method of work of the present utility model is:
When nobody before alarm through out-of-date, the resistance of triode VT1 is very large, and the current potential of its collector is very low, and triode VT2 is in pass short status, the 2nd pin Triggerless of integrated circuit, and alarm does not work;
Someone before alarm through out-of-date, the inductance value of sensing chip changes, the emitter and collector resistance decreasing of triode VT1, the current potential of collector rises, triode VT2 conducting, 2nd pin of integrated circuit obtains DC trigger signal from positive source, exports, promote loudspeaker and play loudspeaker, lumination of light emitting diode after triode VT3 power amplification from the 3rd pin of integrated circuit.
The beneficial effects of the utility model are: structure simple designs is reasonable, improves work efficiency, effectively realizes warning function, prevent maloperation and stranger's power stealing, improve the security of power supply, decrease the generation of mishap.
Accompanying drawing explanation

Accompanying drawing 2 is structural representations of alarm;
In upper figure: display 1, cabinet 2, wave filter 3, interface board 4, alarm 5, air switch 6, gauge tap 7, integrated circuit 8, light emitting diode 9, sensing chip 10, loudspeaker 11; Power supply, switch S B, triode VT1, triode VT2, triode VT3, swept resistance RP, the first resistance R1, the second resistance R2.
Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
A kind of power control unit that the utility model is mentioned, comprises display 1, cabinet 2, wave filter 3, interface board 4, alarm 5, air switch 6 and gauge tap 7, cabinet 2 connects display 1, described display 1 connecting interface plate 4, cabinet 2 is provided with gauge tap 7, described gauge tap 7 connects the alarm 5 of cabinet 2 inside, the inside of described cabinet 2 connects air switch 6 by wave filter 3, and described alarm 5 comprises power supply, switch S B, triode VT1, triode VT2, triode VT3, swept resistance RP, first resistance R1, second resistance R2, integrated circuit 8, light emitting diode 9, sensing chip 10, loudspeaker 11, power supply is by switch S B connecting triode VT1 successively, first resistance R1, triode VT2, integrated circuit 8 and triode VT3, the base stage of described triode VT1 connects sensing chip 10, triode VT2 connects the 2nd pin input end of integrated circuit 8, the 3rd pin output terminal connecting triode VT3 of integrated circuit 8, connecting luminous diode 9 and loudspeaker 11 on the collector of triode VT3.
Wherein, the two ends of triode VT1 swept resistance RP in parallel.
In addition, the second resistance R2 in parallel between the 7th pin of integrated circuit 8 and the 8th pin.
When nobody before alarm through out-of-date, the resistance of triode VT1 is very large, and the current potential of its collector is very low, and triode VT2 is in pass short status, the 2nd pin Triggerless of integrated circuit, and alarm does not work;
Someone before alarm through out-of-date, the inductance value of sensing chip changes, the emitter and collector resistance decreasing of triode VT1, the current potential of collector rises, triode VT2 conducting, 2nd pin of integrated circuit obtains DC trigger signal from positive source, exports, promote loudspeaker and play loudspeaker, lumination of light emitting diode after triode VT3 power amplification from the 3rd pin of integrated circuit.
The above, be only part preferred embodiment of the present utility model, any those of ordinary skill in the art all may utilize the technical scheme correct of above-mentioned elaboration or are revised as equivalent technical scheme.Therefore, any simple modification of carrying out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that the utility model is claimed.
