(5) specific embodiment
Now in conjunction with the accompanying drawings the specific embodiment is described as follows: the license plate theft-proof sensor is installed in license plate fastening nail 3 places, illuminator 1 and photodetector 2 are installed in the both sides of license plate fastening nail 3 respectively, and the emitting surface of illuminator 1 is towards the light detection faces of photodetector 2.The input of the input of illuminator 1, output line and photodetector 2, output line link to each other with corresponding warning treatment circuit.Illuminator 1 can be light-emitting diode, laser, glow lamp, fluorescent lamp etc., and photodetector 2 can be photodiode, photo-transistor, photoconductive cell, photoemissive element, color sensor, infradred sensor, UV sensor etc.Illuminator 1 adopts infrarede emitting diode in the present embodiment, and photodetector 2 adopts photodiode.Compiling adapter 5 is to realize with the element with unidirectional conducting effect, is that the output correspondence of each photodiode connects the input that compiles 1 diode in the adapter 5 with 4 diodes among the embodiment shown in Figure 4.In the present embodiment, 4 photodiodes are sensed the light time that infrarede emitting diode sends, and are in conducting state, and the anodal current potential of photodiode is approximately zero over the ground, makes not conducting of 4 diode D1～D4, therefore, and the no signal alert actuator 6 of delivering newspaper.Warning actuator 6 is used to produce the warning trigging pulse, can be made up of aerotron exclusive disjunction amplifier or the auxiliary components and parts such as resistance capacitance of light even summation, and present embodiment adopts aerotron and auxiliary resistance capacitance to realize.If compile adapter 5 not conductings, the base stage of aerotron BG1 does not just have voltage, collecting electrode and emitter can conductings yet, therefore collecting electrode does not have potential change, collecting electrode does not just have the deliver newspaper trigger end of alert timer 7 of trigging pulse as the output of warning actuator 6 yet, so annunciator is in the state of setting up defences, do not send sound and light alarm.In the time will inserting screw rotating tool and twist fastening nail 3, screw rotating tool must pass license plate theft-proof sensor 4, cuts off the light path between infrarede emitting diode and the photodiode, and photodiode ends because of the light that detects less than luminotron.After photodiode ends, its current potential raises, this current potential is by compiling a diode among cooresponding D1～D4 in the adapter 5, voltage is added to the base stage of aerotron BG1, make base stage and emitter conducting, collecting electrode and emitter conducting subsequently, the current potential of collecting electrode descends, and this variation current potential produces the trigger end that negative going pulse passes to alarm timer 7.Alarm timer 7 usefulness 555 or timing circuit chips such as 556 are realized, present embodiment adopts 556 (U2A) and resistance R 8, capacitor C 3 to realize, time of fire alarming length is by the value decision of resistance R 8 and capacitor C 3, and 556 (U2A) that are triggered send acousto-optic driver 8 with output signal.Acousto-optic driver 8 realized by the components and parts with on-off action, and as relay or light aerotron etc. occasionally, present embodiment adopts 1 two group relay J1, and 1 group of control rattler 9 is 1 group of control light flash device 10 in addition.After the output signal of 556 (U2A) makes relay J 1 adhesive, connect rattler 9 and light flash device 10.Rattler 9 in the present embodiment is active annunciator loudspeaker, if alarm sound is had specific (special) requirements, then rattler 9 can be equipped with corresponding voice driven circuit by the speech chip of meet requirements and export to passive annunciator loudspeaker and get final product.Light flash device 10 also available 555 or general timing circuit chips such as 556 and auxiliary resistance electric capacity realize that the general-duty Der Blink und Abblendschalter is realized on the also available vehicle.The control that present embodiment adopts the general timing circuit chip of 556 (U2B) and auxiliary resistance R16 that determines the light light on and off cycle and capacitor C 8 to realize light actuator 11.Light actuator 11 is realized by the components and parts with on-off action, is 2 relay J 2, J3 in the present embodiment.The output of 556 (U2B) drives relay J 2, the periodic adhesive of J3 and disconnection, realizes the switching of controlling machine motor-car two-way steering indicating light A, B circuit, reaches light flash and reports to the police.Take out if cut off the screw rotating tool of light path between infrarede emitting diode and the photodiode, promptly the light path between light-emitting diode and the photodiode is recovered conducting, and then in the timing of the value decision of R8, C3, it is normal that circuit recovers, and stops to report to the police.If the light path between infrarede emitting diode and the photodiode is cut off always, then the collecting electrode of aerotron BG1 is in active potential always, and annunciator will be in sound, light alarm condition always.
An automobile can only be installed 1 license plate theft-proof sensor 4 on licence plate, also can on the licence plate of front and back, all install or install several license plate theft-proof sensors 4, also can increase the quantity of fastening nail 3 and license plate theft-proof sensor 4 as required, therefore, the quantity of the license plate theft-proof sensor 4 on each car can be as required, be any number between 1 to 8, if change R1 resistance, remove resistance and cooresponding D1～D4 diode or increase resistance and the diode identical with D1～D4 diode among cooresponding R2～R5 with R2～R5 resistance.
Remove license plate theft-proof sensor 4 in the present embodiment and be installed in license plate fastening nail 3 places, all the other are installed in the operator's compartment, they are connected by 4 core cables, and wherein 2 heart yearns are the input and output of light-emitting diode, and 2 heart yearns are input, the output of photodiode in addition.If therefore cutting off 4 heart yearn annunciators will report to the police.Because connection lead has 4 cores, be input, the output of photodiode so can't distinguish any 2 cores, therefore input line that also can not be by the short circuit photodiode and output line and the light sensing state of relieving light electric diode.
When indicator lamp is bright, show that annunciator is in running order.But indicator lamp LED or charactron or light-emitting block can add 1 shell to indicator lamp according to circumstances, and shell needs the part of printing opacity to be made by light transmissive material.Product information directly can be printed on the surface of indicator lamp or shell, or printed matter such as non-drying glue etc. be attached to the inside and outside surface of indicator lamp or shell.Product information is contents such as trade mark, title, production unit, marketing unit, telephone number, anti-false sign.Indicator lamp is guided to the indoor glass port of vehicular drive place by lead, make people see product information on the indicator lamp, play caution robber and promote products by vehicle window.
