Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of light-operated touch circuit, comprise power supply VCC, CD4013D trigger IC, in order to connect the relay K of load, on power supply VCC, be connected with filter circuit 2, filter circuit 2 comprises the electrochemical capacitor C1 that anode is connected with power supply VCC, three capacitor C 3 in parallel with electrochemical capacitor C1, the minus earth of electrochemical capacitor C1; 5 pin, 14 pin of d type flip flop IC connect power supply, and relay K one end connects power supply; 3 pin of d type flip flop IC connect touch electrode M, the 4th resistance R 4, the four resistance R 4 one end ground connection; Between 1 pin of d type flip flop IC and 4 pin, be connected the first resistance R Isosorbide-5-Nitrae pin by the second capacitor C 2 ground connection; 1 pin of d type flip flop IC connects the anode of one the 3rd diode D3, and the negative electrode of the 3rd diode D3 is connected with 11 pin of d type flip flop IC; The other end that 12 pin of d type flip flop IC connect the second resistance R 2, the second resistance R 2 connects the base stage of the first triode VT1, and the collector electrode of the first triode VT1 is connected with relay K; The base stage of the first triode VT1 connects the second photo resistance RG2, and the second photo resistance RG2 ground connection is connected a wire jumper JP1 between the base stage of the first triode VT1 and the second photo resistance RG2; The emitter of the first triode VT1 connects the anode of a light-emitting diode LD, and the negative electrode of light-emitting diode LD connects the 3rd resistance R 3, the three resistance R 3 and connects power supply VCC; The collector electrode of the second triode VT2 connects the anode of the first diode D1, and the negative electrode of the first diode D1 connects power supply VCC; The upper first photo resistance RG1 that connects of power supply VCC, the first photo resistance RG1 other end connects the base stage of the second triode VT2, and the collector electrode of the second triode VT2 is connected with 11 pin of d type flip flop IC, the grounded emitter of the second triode VT2; The base stage of the second triode VT2 connects the 5th resistance R 5, the five resistance R 5 ground connection; 6 pin of d type flip flop IC, 7 pin, 8 pin, 10 pin ground connection.
The light-operated touch circuit of one of the present utility model, the course of work is as follows:
Touch electrode M of finger touch, human body forms the pressure drop of alternation induced voltage on R4, its positive half cycle signal enters the 3rd pin of d type flip flop IC, 1 pin of d type flip flop IC is high potential by original electronegative potential saltus step, this high potential charges to the second capacitor C 2 through the first resistance R 1, make the current potential that 4 pin are increase, in the time rising to reset (Reset) current potential, 1 pin recovers electronegative potential.So touch electrode M of every touch, 1 pin is just exported the positive pulse wave of a fixed width.This positive pulse wave will directly be added to 11 pin of d type flip flop IC, and the 12 pin current potentials of d type flip flop IC are changed once.In the time that 12 pin are high potential, the base stage of the first triode VT1 sees through the second resistance R 2 and obtains forward current and open-minded, makes relay K action, the action of relay and then the action of control load.Thus, every touch one-time electrode sheet M, just can realize that relay " leaves " or the action of " pass ".
The second triode VT2 plays the effect that control switch resets in circuit, when in natural daylight illumination, inadequate and switch is closed, 12 pin are high potential, in the time that natural daylight illumination reaches requirement, the resistance of the first photo resistance RG1 diminishes, and makes the second triode VT2 conducting, produce a positive pulse, this positive pulse wave is directly added to 11 pin, and relay K is disconnected, and does not reach standard and phenomenon that load is lit and there will not be when natural daylight illumination.
When the natural daylight illumination that is irradiated to the second photo resistance RG2 reaches requirement, the first triode VT1 cut-off, relay K is in forcing off-state.
The second diode D2, the 3rd diode D3 the 1st pin and the 9th pin to CD4013D trigger IC plays buffer action, prevents phase mutual interference.
Whether JP1 adopts light-operated for selection.When JP1 during in on-state light circuit is worked, under the satisfactory condition of illumination, while touching touch electrode M, can not disconnect or closing relay K, when illumination is undesirable, while touching touch electrode M, can disconnect or closing relay K load.
When JP1 is during in off-state, light is inoperative to circuit, regardless of illumination, can both disconnect or the load of closing relay K while touching relay K.
In the time being irradiated to the natural daylight illumination of the second photo resistance RG2 and reaching requirement, the first triode VT1 cut-off, relay K is in forcing off-state.Finger touch electrode M, disconnects or closing relay K load.
