Description

A kind of new automobile anti-theft warning circuit

Technical field

The utility model relates to field of security technology, in particular to a kind of new automobile anti-theft warning circuit.

Background technique

With the raising of social development and living standards of the people, automobile gradually comes into common people house.Meanwhile it carrying out anti- Robber's measure is very necessary, if stolen, a no small loss, the antitheft and safety problem of automobile can be brought to car owner Gradually start of interest by people.According to incompletely statistics, the whole nation has 340 vehicles to be stolen, robbed daily, this gives people's property band Carry out very big loss.Therefore, designing one kind and safely, quickly, effectively instead stealing vehicle fitting is the effective hand for protecting car owner's interests Section.

Utility model content

Therefore, for above-mentioned problem, that the utility model proposes a kind of structures is simple, easy to use, when robber steals vehicle The new automobile anti-theft warning circuit of car owner can effectively be reminded.

To solve this technical problem, the utility model takes following scheme: a kind of new automobile anti-theft warning circuit, including Photo resistance, light control alarm integrated circuit, switch, audio amplifier circuit, single-chip microcontroller and GPRS module, the light control alarm are integrated Circuit be KD9562B chip, the photo resistance be set to automobile starting run indicator seat on and photo resistance both ends respectively with The second pin of KD9562B chip is connected with third pin, and the light control alarm ic output is put with audio respectively Big circuit input end is connected with single-chip microcomputer input, and alarm signal is converted to letter through GPRS module by the single-chip microcomputer output Breath is sent to car owner's mobile phone, and the switch ends are connected with the 4th pin of KD9562B chip and the 5th pin respectively.

It is further to improve, it further include external oscillation resistance R1, the both ends external oscillation resistance R1 and KD9562B chip The 6th pin and the tone that is connected for adjusting alarm of the 7th pin.

Further to improve, the single-chip microcontroller is STM32F103C8T6 chip.

By using preceding solution, the beneficial effects of the utility model are: running instruction by the starting in automobile Photo resistance is set on lamp holder, will be closed the switch when car owner leaves, circuit is at preparation or alarm condition, when automobile once Non- is car owner's starting, and start indicator lamp shines, and photo resistance is irradiated by light, and circuit is the work that is triggered, and light control alarm is integrated Circuit is immediately controlled audio amplifier circuit work and issues loud alarm, while light control alarm integrated circuit sends trigger signal To single-chip microcontroller processing, automobile starting information is transmitted to GPRS module by single-chip microcontroller, then is converted to information by GPRS module and is sent to vehicle On main mobile phone；Vehicle stopping time start indicator lamp does not work, irradiation that photo resistance is unglazed, and circuit is in static wait state, audio amplification Circuit stops working into silent state.When car owner voluntarily starts car, as long as alarm would not be issued by disconnecting switch, open Hided hidden place is closed, so that car owner can effectively receive information reminding car owner when robber steals vehicle again not by robber It was found that structure is simple, easy to use；It is further to improve, i.e., by leading in external one external oscillation resistance R1 of KD9562B The size for changing R1 is crossed, the tone of alarm can be changed, it can wide popularization and application.

Detailed description of the invention

Fig. 1 is the circuit diagram of the utility model embodiment.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

With reference to Fig. 1, the new automobile anti-theft warning circuit of preferred the utility model, including photo resistance GR, light-operated report Alert integrated circuit, switch S, external oscillation resistance R1, audio amplifier circuit 1, single-chip microcontroller 2 and GPRS module 3, the light control alarm Integrated circuit is KD9562B chip, and the photo resistance GR is set to automobile starting run indicator 4 upper and photo resistance GR two End be connected respectively with the second pin of KD9562B chip and third pin, the first pin of the KD9562B chip respectively with 1 input terminal of audio amplifier circuit is connected with the 18th pin input end of single-chip microcontroller 2, and 2 output end of single-chip microcontroller is through GPRS mould Alarm signal is converted to information and is sent to car owner's mobile phone by block 3, and the switch S draws with the 4th of KD9562B chip the at both ends respectively Foot and the 5th pin are connected, the both ends external oscillation resistance R1 and the 6th pin of KD9562B chip and the 7th pin phase The tone for adjusting alarm is connected, the single-chip microcontroller 2 is STM32F103C8T6 chip.

The utility model will be opened by the way that photo resistance is arranged on the starting run indicator seat of automobile when car owner leaves It closes and closes, circuit is at preparation or alarm condition, is car owner's starting when automobile is once non-, start indicator lamp shines, photosensitive electricity Resistance is irradiated by light, and circuit is the work that is triggered, and light control alarm integrated circuit, which is immediately controlled audio amplifier circuit work and issues, to be rung Bright alarm, while light control alarm integrated circuit sends trigger signal to single-chip microcontroller processing, single-chip microcontroller is by automobile starting information It is transmitted to GPRS module, then information is converted to by GPRS module and is sent on car owner's mobile phone；Vehicle stopping time start indicator lamp does not work, photosensitive Irradiation that resistance is unglazed, circuit are in static wait state, and audio amplifier circuit stops working into silent state.When car owner voluntarily When starting car, as long as alarm would not be issued by disconnecting switch, hided hidden place is switched, so that car owner is in robber Information reminding car owner can be effectively received when vehicle steathily and is not found by robber, structure is simple, easy to use；Further change Into that is, by the way that the sound of alarm can be changed by changing the size of R1 in external one external oscillation resistance R1 of KD9562B It adjusts, it can wide popularization and application.
