Abstract
The present invention discloses an intelligent wireless long-range warning method and its device used for auto anti theft, wherein a signal input end of a controller receives a cutoff signal, an AINO end thereof receives an angle signal of a tilting cape sensor arranged at an output end of an alarm sensor, an IGT end of the controller receives a low-level pulse signal of a communication module, which triggers the controller to work, a serial communication end of the controller transmits the data to the communication module, an SIM card is used as a memorizer of alarm telephone number and is correspondingly connected with a corresponding pin of the communication module, thus completing the pickup and memory of telephone number. A warning system is supported by a communication network and combined with an electronic circuit, thus ensuring that the owner of the car can keep the intelligent linkage guard against theft during the parking time of car. The pressure, the angular displacement or the rotation angle-typed sensor are used to gain the alarm signal, and to send the alarm message to cellphones and fixed phones. When the sealing is happened, the hunting speed of a bodywork is detected to gain an offset, thus sending the message to the owner of the car, thereby ensuring that the owner of the car get to the scene of robbery in time, therefore the thieves is arrested on one hand, and the car is protected on the other hand.
Description
Technical field
The present invention discloses the unlimited remote alarm method of a kind of intelligent vehicle anti-theft, is to the improvement of existing automobile anti-theft alarm technology, and the warning device that is applicable to this method also is provided simultaneously, belongs to the electronic alarm device technical field.
Background technology
Popular in the market many alarms and security systems for automobiless.Though but antitheft mode is various, can simply reduce three major types substantially: mechanical type alarm, electronic anti-theft device and network theftproof device.The mechanical type anti-theft device is simple, the most cheap on the market a kind of anti-theft device, its principle is very simple, its advantage is a low price, shortcoming is antitheft not thorough, electronic anti-theft device is to install on automobile that electronic anti-theft equipment reaches the purpose of monitoring vehicle and warning additional but be not intelligent, also reports by mistake sometimes.The gps satellite positioning system should present at last all more advanced at home and abroad anti-theft technique.But it is also not too universal at present, and most important reason is that price is too high.
Summary of the invention
The invention provides the unlimited remote alarm method of a kind of intelligent vehicle anti-theft, theftproof performance is tightly reliable, powerful, do not have wrong report when reporting to the police, and noiseless and noiselessness pollutes.
The present invention also provides a kind of warning device of making based on said method, has overcome shortcomings such as the intelligent difference of existing auto alarm method.
Technical solution of the present invention is as follows:
Constitute warning device by controller MCU, obliquity sensor ORS-CLM, two four inputs with door, SIM card and GPRS communication module, its power unit adopts vehicle-mounted level+12V power supply power supply, through providing+D.C. regulated power supply of 3.3V for system after the level conversion.SIM card is finished the extraction and the storage of telephone number as the corresponding connection of respective pins of CCDET1, the CCDET2 of the storer of alarm call number and MC39i, CCIO, CCCLK, CCRST; After controller MCU receives Parking signal LOCK, the angle signal that begins car plate is stolen the OUT pin output of the signal of signal S1, preceding cover start signal S2, back cover start signal S3, four car doors and obliquity sensor ORS-CLM is gathered and is monitored, give low level pulse signal of GPRS communication module by the IGT pin, trigger its work, utilize RXD and TXD serial communication pin to transfer data to communication module again, communication module is reported to the police according to the alarm call of SIM card storage.
Core controller MCU selects for use is low-power consumption, high stable, have the high-performance MCU of A/D converter on the sheet.This MCU is in dormant state at ordinary times, when car owner's Parking and when locking a door, can produce a Lock signal, and this device utilizes this Lock signal as the down trigger source, wakes the park mode of MCU up, enters normal operating conditions.
74HC21 is two four inputs and door, wherein signal L1, the L2 of four car door openings, L3, L4 produce the external interrupt INT0 of MCU controller by 74HC21, and car plate is stolen signal S1, preceding cover start signal S2, back cover start signal S3, door lock signal LOCK produce the MCU controller by 74HC21 external interrupt INT1.
ORS-CLM is an obliquity sensor, when MCU enters operate as normal dress attitude, MCU is worth inclination angle at this moment as standard value, and inclination angle state after this monitored in real time, in case there is the people illegally into the car or produce tire and steal situation, this moment, this inclination angle value changed, here, through the experiment algorithm proof, when the inclination angle is worth greater than 1.5 °, think promptly the pilferage situation take place that at this moment MCU and GPRS communication module MC39i carry out communication, make it carry out call alerts or SMS alarm, notify car owner or 110 to take measures on customs clearance according to predefined telephone number among the SIM Card.
Number among the SIM Card can be provided with the form of short message by the car owner, the convenient use.
Good effect of the present invention is: have a remote automobile Parking guard against theft and alarm system for a kind of, it mainly relies on existing communication network, alarm as CDMA, RGSM form in conjunction with electronic circuit makes car owner and Parking automobile keep intelligent linkage antitheft all the time.Employing utilizes the sensor of pressure, angular displacement or corner formula to extract alerting signal, and the information of reporting to the police is sent to mobile phone and fixed telephone.When taking place to steal car and tire; send information by the displacement that frequency produced that detects vehicle body swing to the car owner, because for wireless telephone sends information, the robber is difficult for realizing; guaranteed the car owner stolen scene that arrives in the very nick of time, promptly caught the robber and protected vehicle again.When this device can be realized automobile parking theftproof performance tightly reliable, powerful, do not have wrong report when reporting to the police, noiseless and noiselessness pollutes; Alarm is simple in structure, volume is little, low in energy consumption, highly sensitive.
