Abstract

The utility model discloses a mobile-telephone type auto anti-theft device which comprises a power circuit, a micro-processing control circuit and a trigger circuit. The micro-processing control circuit is connected with a decoding circuit which is composed of a decoder, and the decoding circuit is connected with a high-frequency receiving circuit. The output end of the micro-processing control circuit is provided with a control relay and a vocal and alarming drive circuit. The device is characterized in that the output end of the decoding circuit is provided with a signal amplification circuit; the output end of the signal amplification circuit is provided with a time counter which is connected with the control relay by the trigger circuit. The device can notify the auto owner by the mobile telephone when the auto is stolen and lead the auto owner to control the action of the auto from a long distant by the mobile telephone when finding that the auto is lost, thereby having good anti-theft function.

Description

A kind of vehicular telephone formula alarms and security systems for automobiles

Technical field

The utility model relates to the automobile burglar equipment technical field, more particularly relates to a kind of device of realizing anti-theft feature by the vehicular telephone Control of Automobile.

Background technology

Automotive theft proof system all is that people concentrate the focus of paying close attention to for a long time, along with making rapid progress of development in science and technology, and the progressively raising of people's quality of life, people are also more and more higher to the requirement of automobile burglar function.Car alarm commonly used is to utilize the vibration sensor induction suffered vibration of automobile and the sound that gives the alarm, but because not anti-wrong report measure, any small vibration all can cause makes a false report and wrong report, influences and disturb other people work and life.For this reason, people improve on this basis, effectively prevent wrong report, as Chinese patent application number is 01214956, the applying date is January 17 calendar year 2001, denomination of invention is a mobile phone formula alarming device for automobile anti-theft, include wireless open-type and remove projector and receptor, sensor and control engine off and sounding alarm circuit, it is characterized in that having a central process unit, its input end is respectively with each sensor and pass through phase inverter, decoder is connected with receptor, its mouth respectively with central locking control, driving circuit, the danger signal lamp drive circuit, the sounding alarm driving circuit, engine off driving circuit and be connected with the vehicular telephone annunciator by interface circuit.The interface circuit of this patent by being made of optic coupler sends the dialing instruction to vehicular telephone, thereby can make alarm speaker and default phone while sounding on the car, reduced wrong report effectively, in time reminds the car owner, reduces the loss.Its shortcoming is that the car owner can only move by the distance control auto alarm, but can not in time allow automobile stop any action, if in a single day automobile leaves densely populated place and just be difficult to recover, can only play the effect of strick precaution, and can not tackle the problem at its root.

Summary of the invention

The purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of can not only in time notify the car owner by vehicular telephone when automobile is stolen, and can make the car owner find to lose car the time, by the vehicular telephone formula alarms and security systems for automobiles of vehicular telephone distance control automobile action.

The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of vehicular telephone formula alarms and security systems for automobiles, comprise power circuit, little control and treatment circuit, trigger circuit, little control and treatment circuit is connected with a decoding circuit that is made of demoder, be connected with high-frequency RF acceptor circuit and transmission circuit on it, the mouth of little control and treatment circuit is provided with control relay, the sounding alarm driving circuit, it is characterized in that: the mouth of described decoding circuit is provided with signal amplification circuit, the mouth of signal amplification circuit is provided with time counter, and this time counter links to each other with control relay by trigger circuit.

As further specifying of such scheme, the mouth of described time counter is provided with signal amplification circuit, and this signal amplification circuit is connected with latch cicuit and time counter.

The energizing signal of the input end of described trigger circuit is the direct supply of 1～12V.

Time counter on the described signal amplification circuit mouth connects audio signal input end, and its signal is the direct supply of 0.5～1V, and the delay time of time counter is 3～5 seconds.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model adopts increases the vehicular telephone control system on the anti-theft system of former car, the mouth signalization amplifying circuit of the decoding circuit by little control and treatment circuit, on the mouth of signal amplification circuit time counter is set, time-delay was 3～5 seconds when sound signal on the time counter input end was entered, under signal does not disconnect, just enter magnifying state, be amplified into note and deposit circuit, and by the trigger circuit triggers control relay, realize that the vehicular telephone Control of Automobile stops, stoping the burglar that car is stolen.

Description of reference numerals: 1, signal amplification circuit 2, time counter 3, signal amplification circuit 4, audio signal input end 5, trigger circuit input end

The specific embodiment

As Fig. 1, shown in Figure 2, a kind of vehicular telephone formula of the utility model alarms and security systems for automobiles, comprise power circuit, little control and treatment circuit, trigger circuit, power circuit is by voltage stabilizer, anti-recoil voltage diode and filter capacitor are formed, trigger circuit are installed in the car door periphery, its input end connects the car door opening circuit for detecting that is made of aerotron, when car door is illegally opened, the car door opening circuit for detecting will send a signal to trigger circuit, the energizing signal of the input end 5 of trigger circuit is the direct supply of 1～12V, this little control and treatment circuit is connected with a decoding circuit that is made of demoder, be connected with high-frequency RF acceptor circuit and transmission circuit on it, the mouth of little control and treatment circuit is provided with control relay J1, J2, J3, the sounding alarm driving circuit, the mouth of decoding circuit is provided with signal amplification circuit 1, the mouth of signal amplification circuit 1 is provided with time counter 2, this time counter 2 links to each other with control relay J3 by trigger circuit, the mouth of time counter 2 is provided with signal amplification circuit 3, and this signal amplification circuit 3 is connected with latch cicuit and time counter.Time counter 2 on signal amplification circuit 1 mouth connects audio signal input end 4, and its signal is the direct supply of 0.5～1V, and the delay time of time counter is 3～5 seconds.

During use, time-delay was 3～5 seconds when sound signal entered, under signal does not disconnect, enter amplification, amplified signal can enter note and deposit circuit, and the signal of trigger circuit enter the note deposit and need not delay time, self-locking 10 seconds, then, its mouth relay J 2 actions 2 times, vehicular telephone " is answered " keyed jointing and is led to twice, and the car owner's number that will prestore is transferred to, and the car owner can monitor vehicle condition, and can be by vehicular telephone by strong, import corresponding number, its information via output circuit is sent to little control and treatment circuit, and car oil circuit and circuit are cut off in its mouth relay J 3 actions after treatment; At ordinary times, the car owner also can directly dial the number of car phone, and output relay J1 action connects with it after little control and treatment circuit is handled, and the car owner can finish automobile burglar by button, monitor function is set.
