Field of the Invention The present invention relates to a car anti-theft system and an anti-theft method thereof, and more particularly to a car anti-theft system capable of promptly notifying a car owner of a stolen message and an anti-theft method thereof. [Prior Art] According to the rapid development of the economy, the number of cars has increased rapidly. At the same time, the number of cars stolen is also on the rise. Therefore, various car anti-theft systems have emerged. Existing car anti-theft systems commonly use mechanical locks, such as lock gears and lock brakes, but mechanical locks can not inform the owner of the car stolen information. Therefore, the owner usually installs an electronic alarm on the car, but sometimes the electronic alarm will falsely report and scream for a long time due to contact and thunderstorms, and the owner cannot know the car in time when the owner is away from the car. Pirates. In recent years, with the development of electronic technology, new car anti-theft products have emerged, such as electronic oil circuit locks and circuit locks. Although these car anti-theft products have increased the difficulty of car theft, the car owner still can't know the stolen information of the car in time. Therefore, how to provide a car anti-theft system capable of promptly telling the owner of the car to be stolen and the position of the car has become an urgent problem to be solved. SUMMARY OF THE INVENTION One object of the present invention is to provide a 200843984 eight-car anti-theft system for the defects of the above-mentioned prior art, which can promptly inform the owner of the car being stolen and the position of the car. The second object of the present invention is to provide a car anti-theft method capable of promptly informing the owner of the car of the car of the drum in response to the above-described drawbacks of the prior art. To achieve the above object, the present invention provides a car anti-theft system. The car anti-theft system includes a barometric sensor, an amplifying circuit, a cell phone system, and a positioning system. The air pressure sensor is for sensing a change in air pressure in the automobile and outputting a signal. The amplifying circuit is connected to the air pressure sensor for amplifying the output signal of the air pressure sensor and outputting an amplified signal. The mobile phone system is connected to the amplifying circuit for receiving and processing the amplified signal transmitted by the amplifying circuit and informing the owner of the car the stolen message. The positioning system is coupled to the handset system to track and determine the location of the car. In order to achieve the above object, the present invention provides a vehicle anti-theft method, comprising: sensing a change of air pressure in a car through a gas pressure sensor and outputting a signal by the air pressure sensor; connecting the air pressure sensing through the amplifying circuit The signal outputted by the air pressure sensor is amplified to output an amplified signal; the amplified signal outputted by the amplifying circuit is received and processed on the amplifying circuit through the mobile phone system, and the vehicle owner is notified of the stolen message; The system is connected to the phone system to track and determine the location of the car. 200843984 'The vehicle is reduced as described above, the car anti-theft (4) and the anti-theft side of the invention are determined by a pneumatic sensor sensing vehicle (10) or the window is destroyed (4) to determine whether the car is "designed to make the car The domain is able to know the stolen information of the vehicle in time, and determines the occurrence of the stolen phenomenon of the car by the positioning system. [Embodiment] In order to explain the technical content, the achieved purpose and the effect of the present invention in detail, the following embodiments are combined and coordinated. The drawings are explained in detail. Referring to FIG. 1 , the automobile anti-theft system i of the present invention includes (4) a mobile phone system 10, a pneumatic sensor 20, a GPS positioning system 3〇, and an amplifying circuit 40. The I-pressure sensor 20 is connected to the amplifying circuit 40, and is enlarged. Both circuit 40 and GPS positioning system 30 are coupled to a GSM handset system. When the owner gets off the vehicle, the vehicle anti-theft system is used to detect the change of the air pressure generated by the air flow to detect whether the door of the car is turned on or the window of the car is damaged. # When the car door is opened or the window is broken, the car_air pressure changes, the air pressure sensor 2{) will sense the air pressure change in the car and generate a gas pressure change signal; the amplification circuit 仞 feels the air pressure sensor 20 The measured air pressure change signal is amplified; the gsm mobile phone system 1 receives the amplified air pressure change signal output by the amplifying circuit 40 and uses the GSJV [mobile phone system 1 〇 instant communication function to send a car sub-message to the vehicle owner, and the GPS positioning system 30 issues The location information of the car to determine the current location of the car facilitates real-time tracking of the car. 200843984, Ming Mai read the first figure, the model of the air pressure sensor 20 used in the present invention is a 24PCAFA6D air pressure sensor. The air pressure sensor 2 has a first straight 21, a first straight 22, a central sensing element 23, a first pin 24, a first pin 25, a second pin 26, and a fourth pin 27. The gas is introduced into the first straight tube 21 and the second straight tube 22 at both ends of the air pressure sensor 20, and the first straight cymbal 21 is measured by the central sensing element 23, and the front 21 士 ^ μ ^ The difference in the magnitude of the pressure is then output as a voltage. The air pressure sensor belongs to the passive sensor 'requires an external power supply to it - the excitation voltage makes it work, and the output voltage will increase as the pressure 嶋'. The first to fourth pins 24 of the air pressure sensor 20, ? $, 〇 < 25 26, 27 represents the following line: Brother one pin 24 = Vs ( + ) Second pin 25 = 〇 utput (+) Second pin 26 = Ground (-) Fourth pin 27=〇utpUt(—) Please refer to the third figure, where the first brother connects 24 to the positive output of the external power supply and the foot 26 is grounded. The second leg 25 is connected to the negative input terminal of the Γ1 through a resistor R. And the negative input end of the amplifier 41 also passes through the - input terminal, and the positive input terminal of the positive σ ( of the (4) 1 ternary device 41 is also connected through a resistor R to the output terminal of the amplifier terminal 41 of the amplifier 41. The resistor (4) and the amplifier 41 group 2 circuit 40' are amplified by an electric house signal 8 200843984 which is rotated at both ends of the second leg 25 and the fourth leg 27. The amplified signal is sent from the output of the A||41 to the processing circuit of the GSM mobile phone system 10 (not shown), and the processing signal of the mobile phone system 10 processes the amplified signal output from the amplifier 41 and issues the car. If the car is stolen, the GSM mobile phone system ig sends the car theft information to the owner through its instant communication function. The GPS positioning system 30 used in the present invention is a conventional technique. When the rut of the car is turned on, the air pressure sensor 20 mounted on the GSM mobile phone system 10 senses the change of the air pressure in the vehicle, and then starts. The GPS clamp system 30 notifies the vehicle owner and related agencies (such as the police, etc.) to track the car and determine the current location of the car. As described above, the automobile anti-theft system and the anti-theft method thereof according to the present invention sense that the line pressure in the automobile changes and generates money when the automobile door is opened or the automobile window is broken by the air pressure sensor 20, and is amplified and transmitted by the amplifying circuit 40. The GSM mobile phone system 1G is sent to the owner of the GSM mobile phone system 1 to immediately notify the owner of the stolen signal, and the car is tracked by the GPS positioning system and the position of the car is determined. The invention relates to the "automobile defense system (four) system and its anti-theft method".
