Embodiment
Referring to figs. 1 through Fig. 5, embodiment of the present utility model is described further.
A kind of power distribution cabinet, comprises cabinet 1 and cabinet door 2, is provided with switching device 3 in cabinet 1; Cabinet door 2 is provided with alarm set, and alarm set comprises: human body sensing unit, in response to the close of human body or away from the corresponding induced signal V1 of output; Infrared transmitter 2004, is installed in cabinet 1, for sending infrared signal; Infrared remote receiver 1005, is installed on cabinet door 2; Control unit 300, exports corresponding control signal Vc in response to induced signal V1 and detection signal V2 value; Tip element 400, in response to control signal Vc to start or to close prompt facility; And power subsystem 500, for providing operating voltage for alarm set.
Be worth illustrate time, when installation infrared reflector 2004 and infrared remote receiver 1005, the infrared signal that infrared transmitter 2004 should be made to send is right against outside cabinet 1, and infrared remote receiver 1005 is arranged on after on cabinet door 2, when cabinet door 2 is fastened, infrared remote receiver 1005 just can receive this infrared signal.
With reference to Fig. 2 to Fig. 5, the physical circuit of alarm set is described in detail:
In the present embodiment, this human body sensing unit comprises human inductor 6, and its concrete circuit structure please refer to Fig. 4, and the present embodiment repeats no more.In addition, this human inductor 6 is arranged on cabinet door 2.
With reference to Fig. 2, infrared remote receiver 1005 comprises: infrared receiving terminal, and model is HS0038B; First resistance; Wherein, the positive pole of infrared receiving terminal is coupled to a VCC voltage, minus earth, and output is coupled to control unit 300 by this first resistance, with to control unit 300 output detection signal V2.
With reference to Fig. 3, infrared transmitter 2004 comprises: resistance R4 ~ R6, infrared diode D1D1 and NPN triode Q2; Wherein, the negative electrode of infrared diode D1 is coupled to the collector electrode of NPN triode Q2, and the anode of infrared diode D1 is coupled to a VCC voltage by resistance R1; One end of resistance R2 is coupled to this VCC voltage, and the other end is coupled to the base stage of NPN triode Q2; One end of resistance R3 is coupled to the base stage of NPN triode Q2, other end ground connection; The grounded emitter of NPN triode Q2.
With reference to Fig. 2, control unit 300 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 output of infrared remote receiver 1005, to receive this detection signal V2, second input of OR-NOT circuit N1 is coupled to the output of human inductor 6, to receive this induced signal V1; The output of OR-NOT circuit N1 is for exporting this control signal Vc.
With reference to Fig. 2, Tip element 400 comprises NPN triode Q1 and buzzer 7.Wherein, the base stage of NPN triode Q1 is coupled to the output of OR-NOT circuit by resistance R2, is coupled to VCC voltage with the collector electrode receiving this control signal VcVc, NPN triode Q1 by resistance R3; The positive pole of buzzer 7 is coupled to the emitter of NPN triode Q1, minus earth.
Therefore, the operation principle of alarm set is, after staff opens cabinet door 2, infrared remote receiver 1005 does not receive infrared signal, and the detection signal V2 of output is low level; Meanwhile, because staff is now near human inductor 6, so human inductor 6 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 Q1 is turned off, and buzzer 7 does not work.When cabinet door 2 does not shut, if staff leaves, the induced signal V1 of human inductor 6 output low level, this detection signal V2 is still low level simultaneously, so OR-NOT circuit exports the control signal Vc of high level, and make NPN triode Q1 conducting, buzzer 7 works.
