Abstract
The utility model relates to a GSM mobile phone vehicle anti-theft alarm which is composed of a shell, a power supply, a GSM mobile phone, a processing unit, an outgoing call voice dialing unit, a mobile phone remote control unit on the basis of a single chip computer, an anti-theft sensor and an alarm control circuit. The utility model is characterized in that the utility model can utilize an obsolete old GSM mobile phone to obtain a vehicle control remote alarm function by a mobile earphone interface combining a single chip computer and a peripheral element. The anti-theft alarm which dispenses with the refit of the GSM mobile phone is favorable to the environmental protection reclamation of old mobile phones and equipment investment reduction; the anti-theft alarm with easy installation and simple setting causes installation and use cost of a vehicle to be reduced obviously.
Description
Technical field
The utility model relates to a kind of GSM mobile handset car alarm of equipment.
Background technology
Along with development and the continuous of family-sized car with Ji are popularized, automobile burglar also becomes people's focus of attention gradually, and existing car alarm is a kind of indirect type of alarm, can not in time find larceny.Even the limited noise of reporting to the police but producing of traditional in addition car alarm alarm range allows the people around suffer untold misery, after automobile is stolen, can't know the position that automobile is current, can't the Long-distance Control stolen vehicle.
Summary of the invention
Therefore, the purpose of this utility model is to overcome the above-mentioned deficiency of prior art, a kind of GSM mobile handset car alarm is provided, when vehicle is stolen, can lead to GSM mobile handset and send alarm signal to the car owner, after the car owner finds that vehicle is stolen, as long as in the place that the GSM network signal covers, can orient vehicle location exactly, the car owner can and report to the police with any making call GSM mobile handset car alarm remote control stolen vehicle outage.
The technical scheme that technical problem adopted that the utility model solves is: a kind of GSM mobile handset car alarm, by shell, power supply, GSM mobile handset, processing unit, exhalation phonetic dialing unit, SCM Based mobile phone remote control unit, theft-proof sensor, alarm control circuit is formed, it is characterized in that: described control relay is connected with single-chip microcomputer, the other end of single-chip microcomputer and sound circuit, automatic off-hook on-hook circuit, the DTMF decoding circuit connects, the vibration alarming circuit is connected with the phonetic dialing circuit, sound circuit, automatic off-hook on-hook circuit, the DTMF decoding circuit, the phonetic dialing circuit is connected with earphone interface of mobile phone, and earphone interface of mobile phone is connected with mobile phone.
Described phonetic dialing is voice recording and playback ic ISD1420, and processing unit is the AT89C52 single-chip microcomputer, and power supply is a battery.
Described mobile phone and single-chip microcomputer are connected to the earphone interface of mobile phone, and its connecting line is the handset earphone line.
The beneficial effect of this technical scheme is: need not the GSM mobile handset repacking of starting shooting; can utilize and eliminate old GSM mobile handset; helping old mobile phone environmental protection reclaims; reduce equipment investment; this burglar alarm is easy for installation to be provided with simply; applied range obviously reduces the installation of vehicle and use cost, is easy to apply.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a GSM mobile handset car alarm internal circuit block diagram;
Fig. 2 is a GSM mobile handset car alarm control section FB(flow block);
Embodiment
As shown in Figure 1, GSM mobile handset car alarm internal circuit annexation is: GSM mobile handset is connected with burglar alarm by the earphone special line, mobile phone is made as automatic-answering back device, when phone is squeezed into, mobile phone automatic off-hook after the ring three times, the dtmf signal input, MT8870 can be the decoded signal of DTMF correspondence by will sending to the AT89C52 single-chip microcomputer with baud rate 9600b/s after Data Receiving and the reduction after decoding, the off hook signal of sending from the P1.7 of AT89C52 single-chip microcomputer drives the conducting of light lotus root inserts dummy load, enters off hook state.After whole assignment procedure is finished or during input password mistake, single-chip microcomputer makes off hook signal revert to high level to disconnect dummy load, enter hook state, behind the controller automatic off-hook, and under the prompting of sound circuit ISD1420, import user's operator password and operational order successively.The DTMF decoding circuit is sent the decoded digital signal of the DTMF that receives into single-chip microcomputer, if password is wrong, system hangs up the telephone automatically; When password is correct, only need to finish sequence of operations successively by the voice prompting.When operation is finished, single-chip microcomputer goes to the normally-open normally-close contact of control relay (hrs4h) to come Control of Automobile circuit and warning circuit according to the affirmation information of returning, when take place alert (as illegally open the door, light a fire, vibrations, system are destroyed), the phonetic dialing circuit, the voice tag that prestores by mobile phone is dialed car owner's alarm call immediately, so far, haveing suffered operating process finishes.
As shown in Figure 2, this burglar alarm is applied to the Long-distance Control automobile burglar, and this control section flow process is as follows: when dialing GSM mobile handset car alarm telephone number, ring 3 seconds can automatic off-hook approximately.Can hear the prompt tone of " password input " behind the automatic off-hook, should input 6 passwords this moment.If the unmodified password of crossing is then imported original password.The input password correctly enters next step, if continuous three times can not correctly be inputed password, and then can automatic hand-up.After the password input is correct, can hear the prompt tone of " function input ", select according to your needs this moment.Control open circuit or shut-off circuit can return previous menu or main menu after replying successfully, finish the back on-hook.
The above is a preferred implementation of the present utility model; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
