Embodiment 2

FIG. 3 is a structural block diagram of Embodiment 2 of the present invention. As shown in FIG. 3, the automobile anti-theft system provided by the embodiment includes: a remote controller 7, a body control module 11, a four-door two-cover signal sensor 8, an ultrasonic sensor 9, and a micro The camera 32, the image processing module 41, the radio transmitting terminal 21 (mobile phone), and the mobile phone 6 on which the owner can receive the multimedia message. The four-door two-cover signal sensor 8 refers to a detecting sensor for distinguishing four doors and a front hatch of the automobile and an open/close state of the rear hatch.

 The whole system can be divided into three parts. The first part is an anti-theft control system consisting of the body control module 11 and sensors. It mainly controls the setting and release of the vehicle's alert status and controls the alarm output load. The second part is the information processing system, here is an image processing system including an image capture device (micro camera 32) for image uptake, processing and transmission. The third part is the feedback display system, which is mainly the mobile phone held by the owner. The owner 6 receives the MMS sent by the processing module and informs the owner.

 The working principle of the anti-theft control system is that it is undefended in the daily use of the automobile, and the normal user does not perform an alarm for the use of the automobile. When unarmed, the body control module has no drive output for the ultrasonic sensor (such as sensor), the sensor does not work, the I/O chip monitors the ignition signal and the door/cover signal in real time, when the door/cover is closed and the ignition switch is in the OFF position. After the remote control gives the blocking signal, the vehicle enters the alert mode and simultaneously drives the ultrasonic sensor to work. At this time, the I/O chip monitors the ignition signal, the gate/cover signal, and the signal input by the ultrasonic sensor through the LIN line in real time. When the ignition switch is turned ON, any door/cover is opened, and the glass is broken and sensed by the ultrasonic sensor, any of the above three conditions will trigger the body control module to enter the alarm mode, and the body control module outputs sound and light alarms, and At the same time, the body control module drives the miniature camera to work. In this part, the ultrasonic sensor can sense the abnormal shaking around the body. For example, when someone tries to open the door and steal the property inside the vehicle, the anti-theft horn and the turn signal are driven by the driving circuit in the body control module to alert the thief.

 The working principle of the information processing system is that the micro camera is driven to work, and the phase is taken through the lens. After the A/D conversion, if it is a digital camera (DV), the A/D conversion is not used to directly enter the buffer, after being cached. After processing to the MCU, it is stored in the dynamic RAM and flash memory of the image processing module, and then the photo is processed into an MMS MMS format by the encoder, and the transmission mode of the wireless communication signal is transmitted through the RF transmitting module (the built-in SIM card slot). Send to the owner's mobile phone (wireless communication network such as: GSM\GPRS\CDMA, etc.). The owner's mobile phone number is saved to the module through the settings. In order to capture the characteristics of the intruder more safely and reliably, the above process will be repeated several times in a period of time. The above-mentioned miniature camera is a camera group that is secretly mounted on a reliable part inside and outside the car, such as a seat mounted on the driver's seat, and mounted on the outside of the car.

FIG. 4 is a flow chart of the second embodiment of the present invention. As shown in FIG. 4, in the working process of the embodiment, when the automobile is in normal use, the anti-theft system of the embodiment does not work, that is, is in an unarmed state. After the car is stopped, the anti-theft system of the embodiment is set to the armed state by the vehicle body control module by using the remote controller. When the vehicle is successfully armed, the body control module monitors the following signals in real time: the ignition switch signal, the door/cover signal, and the ultrasonic wave Sensor input Signal. When the ignition switch is in the ON position, the ultrasonic sensor or other sensor senses an abnormal sound, and the door/cover is opened, the body control module is triggered, and the body control module drives the anti-theft horn and the turn signal alarm. At the same time, the ceiling light is illuminated to alert the periphery of the vehicle, and the body control module activates the driving circuit of the miniature camera to make the miniature camera work. The miniature camera inside the car can take in the photo of the intruder inside the car, and convert, compress and send it to the owner's mobile phone through the image processing module to realize remote alarm. At the same time, the miniature camera outside the car can also take out the image of the car, and send it to the owner of the vehicle in the same way, so that the owner can know the location of the vehicle through the image and find the stolen car in time.
