Embodiment
Referring to figs. 1 through Fig. 4, embodiment of the present utility model is described further.
There is a power distribution cabinet for prompting function of closing the door, comprise cabinet 1 and cabinet door 2, in cabinet 1, be provided with switching device 3; Cabinet door 2 is provided with alarm set, and alarm set comprises: light detecting unit 100, exports corresponding detection signal V2 for the light intensity that detects in cabinet 1; Human body sensing unit, in response to the close of human body or away from the corresponding induced signal V1 of output; Control unit 200, exports corresponding control signal Vc in response to induced signal V1 and detection signal V2 value; Tip element 300, in response to control signal Vc to start or to close prompt facility; And power subsystem 400, for providing operating voltage for alarm set.
With reference to Fig. 2 to Fig. 4, the physical circuit of alarm set is described in detail:
In the present embodiment, this human body sensing unit comprises human inductor 4, and its concrete circuit structure please refer to Fig. 4, and the present embodiment repeats no more.This human inductor 4 is arranged on cabinet door 2.
Light detecting unit 100 comprises: resistance R1, resistance R3, resistance R4, photo resistance R2, charging capacitor C1, NPN triode Q1 and PNP triode Q2.Wherein, one end of resistance R1 is coupled to a VCC voltage; One end of photo resistance R2 is coupled to the other end of resistance R1, the other end ground connection of photo resistance R2; The positive pole of charging capacitor C1 is coupled between resistance R1 and photo resistance R2, minus earth; The base stage of NPN triode Q1 is coupled to the positive pole of charging capacitor C1, grounded emitter; One end of resistance R3 is coupled to the collector electrode of this NPN triode Q1, and the other end is coupled to this VCC voltage; The base stage of PNP triode Q2 is coupled to the collector electrode of this NPN triode Q1, and the collector electrode of PNP triode Q2 is by resistance R4 ground connection, and emitter is coupled to this VCC voltage.
Therefore, the operation principle of light detecting unit 100 is, after cabinet door 2 is opened, the resistance of photo resistance R2 diminishes, the base voltage of NPN triode Q1 is ended by dragging down, and make the base voltage of PNP triode Q2 raise and end, now detection signal V2 is low level; When cabinet door 2 does not shut, the light in cabinet 1 is very weak, PNP triode Q2 conducting, makes detection signal V2 be high level.
Control unit 200 comprises OR-NOT circuit N1, OR-NOT circuit N1 has first input end, the second input and output, the first input end of OR-NOT circuit N1 is coupled to the collector electrode of PNP triode Q2, to receive this detection signal V2, second input of OR-NOT circuit N1 is coupled to human inductor 4 output, to receive this induced signal V1; The output of OR-NOT circuit N1 is for exporting this control signal Vc.
Tip element 300 comprises: NPN triode Q3 and buzzer 5.Wherein, the base stage of NPN triode Q3 is coupled to the output of OR-NOT circuit by resistance R5, is coupled to VCC voltage with the collector electrode receiving this control signal Vc, NPN triode Q3 by resistance R6; The positive pole of buzzer 5 is coupled to the emitter of NPN triode Q3, minus earth.
Therefore, the operation principle of alarm set is, when staff opens cabinet door 2, PNP triode Q2 turns off, and therefore, the first input end of OR-NOT circuit receives low level detection signal V2; Meanwhile, because staff is now near human inductor 4, so human inductor 4 is to the induced signal V1 of the second input output high level of OR-NOT circuit; So control signal Vc of OR-NOT circuit output low level, NPN triode Q2 is turned off, and buzzer 5 does not work.When staff does not shut cabinet door 2 and leaves, the induced signal V1 of human inductor 4 output low level, this detection signal V2 is still low level simultaneously, and so OR-NOT circuit exports the control signal Vc of high level, make NPN triode Q2 conducting, buzzer 5 works.
Below be only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
