Description

A kind of night anti-theft controller

The utility model is an anti-theft controller at a kind of night, belongs to home-use theft-proof electron product.

At present, owing to various reason, it is more to go into room theft phenomenon, and often the robber scouts through long-time, to some family lamp that always do not work night, when total no one is in, always go out for a stroll night or other activist in when not having bright lamp, no one, just go into the room theft, cause any property loss.

The purpose of this utility model is exactly often to travel outside in order to help to solve some worker, family, family does not often work lamp again in no one, evening, cause the difficulty and the problem that cause the family's property loss into the room theft easily, research and design a kind of every day of sky blackout will be lighted automatically, allow outdoor people feel that this family has the people to be in and dare not go into the room theft, after 3～5 hours, lamp can automatically shut down the antitheft self-actuated controller at a kind of night that extinguishes again.

The utility model is realized by following technical proposals: this night anti-theft controller the contour structures synoptic diagram as shown in Figure 1, its circuit block diagram as shown in Figure 2, its circuit theory diagrams are as shown in Figure 3.It is by panel 1, three hole accessory power outlets 2, two hole accessory power outlets 3, keyswitch 4, photosensitive device 5, input power cord 6, input attaching plug 7, end box 8, circuit board connects and composes jointly, its mutual alignment and annexation are: circuit board is installed in the end box, three holes and two hole accessory power outlets 2 and 3, keyswitch 4, photosensitive device 5 is loaded on the panel 1 respectively and is connected with respective point on the circuit board by lead respectively, input power cord 6 one ends are connected with input end on the circuit board, the other end is connected with input attaching plug 7, and panel 1 screws affixed being integral by screw and end box 8; Its circuit is connected and composed jointly by reduction voltage circuit, rectification circuit, filter regulator circuit, electronic DC switch circuit, output control circuit, output circuit, and its interconnected relationship is: rectification circuit is connected with reduction voltage circuit, filter regulator circuit respectively by AC power cord, DC voltage output line respectively; By the filtering voltage regulation output line, the switching signal output line is connected with filter regulator circuit, output control circuit respectively the electronic DC switch circuit respectively; Output control circuit is connected with output circuit by control signal wire.Wherein: reduction voltage circuit is by resistance R ₁, capacitor C ₁Formation is connected in parallel; Rectification circuit is by bridge rectifier module W ₁₀Constitute; Filter regulator circuit is by capacitor C ₂, the voltage stabilizing diode DW formation that is connected in parallel; The electronic DC switch circuit is by triode BG ₁, BG ₂, BG ₃, resistance R ₂～R ₅, R ₁₂, the common parallel-series of photoresistance CdS connects and composes; Output control circuit is by resistance R ₆～R ₈, capacitor C ₃, integration member IC ₁, diode D ₁Connect and compose jointly; Output circuit is by integration member IC2, resistance R ₉～R ₁₁, diode D ₂, the controllable silicon SCR parallel-series connects and composes.This night, the principle of work of anti-theft controller was as follows: alternating current 220V is through C ₁R ₁Step-down, W ₁₀Bridge rectifier, C ₂After the filtering, obtain DC voltage and use for this controller circuitry, when had illumination daytime, the cds photoresistance was subjected to the irradiation of light, and resistance diminishes, and makes BG ₁End BG ₂Conducting, BG ₃End IC ₁No current is supplied with, IC ₂4 pin output electronegative potential, controllable silicon SCR is ended, the output of output circuit no current; After night on the same day, photoresistance cds illumination weakens, and it is big that resistance becomes, BG ₁Conducting, BG ₂End BG ₃Conducting, IC ₁Obtain electric current, IC ₁3 pin output noble potential, be added to IC ₂, make IC ₂4 pin output high level trigger controllable silicon, the controllable silicon SCR conducting, output circuit has electric current output, lamp ZD ignites; Meanwhile, electric current passes through R ₆, C ₃Slowly charging is when being charged to IC ₁Cut-off voltage after, its 3 pin output electronegative potential makes IC ₂4 pin output electronegative potential, controllable silicon SCR is ended, ZD extinguishes, this lighting time is about 3～5 hours.After daybreak, photoresistance cds is subjected to illumination, BG ₃End C ₃Pass through R ₆, R ₁₂Slowly discharge, circuit slowly returns to original state; When at dark, repeat said process again.

The utlity model has following advantage and beneficial effect: (1) is to people frequent or that the long period travels outside, this controller can be at dark, automatically light the desk lamp that inserts on its out-put supply socket, allow outdoor personnel feel that this family has the people to be in, the robber just dare not go into the room theft, plays the home security effect; (2) this controller can make lamp that darkness lights automatically again after 3～5 hours, extinguishes automatically again, to reach power saving and to prolong the life-span of being lit a lamp by point, can make outdoor people feel this household sleep of having turned off the light again, really someone's sensation of being in; (3) the utility model volume is little, and is in light weight, compact conformation, and safety easy to use, and cost is low.

The following describes the book accompanying drawing further specifies as follows: Fig. 1 is the contour structures synoptic diagram of anti-theft controller at night; Fig. 2 is its circuit block diagram; Fig. 3 is its circuit theory diagrams.Among the figure: the 1st, panel, 2 is that three hole accessory power outlets, 3 are two hole accessory power outlets, the 4th, keyswitch, the 5th, photosensitive device, the 6th, input power cord, the 7th, input attaching plug, the 8th, end box.

Embodiment of the present utility model can be as follows: the panel and the end box of anti-theft controller at this night designed, made in (1) by shown in Figure 1, and for example available engineering plastics adopt the method for injection moulding to make panel and end box; Choose small unidirectional keyswitch 4, three holes and two hole accessory power outlets 2,3 then, photosensitive device 5 is installed on the room of reserving on the panel 1 again; (2) by shown in Figure 3, draw PCB is screened components and parts then connection is installed.For example: the optional W of rectifier ₁₀Type bridge rectifier module, the optional cds type of photoresistance, IC ₁Optional 555 types, IC ₂Optional 4N25 type, the optional MC100-6 type of controllable silicon SCR; After circuit board installs, after simple debugging, be installed in the end box; (3) the keyswitch 4, the accessory power outlet 2,3 that are loaded on the panel 1, photosensitive device 5 is connected with respective point on the circuit board respectively by lead respectively, and external input attaching plug 7 is passed end box preformed hole by input power cord 6 be connected with circuit input end on the circuit board, then panel 1 by screw and the fastening one that is connected into of end box spinning, so just practical preferably the utility model.During use, the input power socket board is answered incoming transport 220V power supply, on accessory power outlet 2 or 3, should connect desk lamp, and this night anti-theft controller be positioned over have daytime irradiate light to arrive and evening irradiate light less than the place, every like this darkness, desk lamp will be lighted automatically, lights the back and can extinguish automatically again the midnight after 3～5 hours, both can play antitheft effect at night, and can make electricity consumption few again.
