Detailed ways

The utility model vehicle-mounted MMS anti-theft alarm, as shown in Figure 1, retains the basic structure of the original electronic anti-theft device in design, including the single-chip microcomputer of the central control processing unit, the electronic remote controller and the like. The single-chip microcomputer of the central control processing unit monitors the status of the vibration, ACC ignition, door and other sensing units, controls the oil circuit, door, lights and other circuits of the car, outputs sound, and communicates with the electronic remote control. On this basis, the single-chip microcomputer of the central control processing unit increases two-way communication with the serial port of the main MCU. The main MCU communicates with the user's mobile phone voice, SMS and MMS through the communication module, and adds practical functions such as camera, battery undervoltage alarm, SOS emergency alarm and user management. The main MCU adopts a commercially available ARM chip, and the communication module adopts an ASIMCOM chip.

As shown in Figure 2, when the vehicle is in the defense state, when the sensor unit is abnormal, the central control processing unit sends it to the main MCU according to the established protocol, and the main MCU and the communication module will report the abnormal state (for example, the car is illegally ignited, the foot brake is activated, etc.) step on, etc.) to send a short message to the owner's mobile phone, realizing the remote monitoring of the short message of the user's mobile phone.

As shown in Figure 3, after the vehicle-mounted multimedia message anti-theft monitoring alarm device receives the short message, it judges whether the number is authorized, if not, it does not process; if it is a number with authority, it judges whether the command is valid, and if it is invalid, it will reply the short message of the correct command prompt; If it is valid, the main CPU sends commands to the central control processing unit for execution according to the protocol. For the instructions that need to return the execution results, the central control processing unit sends the execution results to the main MCU according to the established protocol, and the main MCU and the communication module send the execution results to the car owner. The mobile phone realizes the SMS remote control of the user's mobile phone.

After the car owner receives the abnormal alarm text message, according to the actual situation, if he needs to take a photo to check the situation in the car, send the corresponding command text message to the number of the car MMS anti-theft monitoring alarm. After receiving the instruction, the car MMS anti-theft monitoring alarm starts the camera device Take pictures and compress them into JPEG format pictures. The picture data is packaged by the main MCU and sent to the owner's mobile phone through the communication module in the form of MMS. The camera is a large-angle spherical structure that can capture the entire scene of the car. The owner can intuitively check whether someone has illegally invaded the car, whether the door has been opened or damaged, etc., as shown in Figure 4.

As shown in Figure 5, when the car owner encounters hijacking or other emergencies while driving, the car owner presses the concealed button, and the car multimedia message anti-theft monitoring alarm takes pictures of the situation in the car, and sends multimedia messages to the 3 alarm numbers in turn. (Generally set as the mobile phone of the car owner's relatives and friends), relatives and friends judge the situation according to the photos and provide assistance.

As shown in Figure 6, after the mobile phone with the authorized number sends a call interception command, the car MMS anti-theft monitoring alarm will call back, and the authorized number can listen to the movement in the car by answering the call.

As shown in Figure 7, after the vehicle-mounted multimedia message anti-theft monitoring alarm receives the incoming call information, it judges whether the number authorized to answer, if not, then hangs up; The numbers authorized to answer can be landlines, group short numbers, etc.

As shown in Figure 8, the car multimedia message anti-theft monitoring alarm has a battery voltage monitoring circuit module. When the car battery voltage is lower than 9.5V, the car multimedia message anti-theft monitoring alarm first performs debounce processing. If the battery voltage is indeed too low, A text message will be sent to remind the car owner to charge the car battery in time

As shown in Figure 9, the car owner can send a text message to authorize the car MMS anti-theft monitoring alarm. Three authorized numbers can be set. After the authorized number is successfully set, a text message will be sent back. The short message of the abnormal situation of the car is only sent to the authorized number 1 (generally the owner's number), and the authorized number does not have the authority to carry out the remote control and query of the car. The operation of setting the alarm number and answering number and changing the password is roughly the same, except that different instructions are sent. Three alarm numbers can be set, which are generally the mobile phones of the car owner's relatives and friends. When the car owner encounters an emergency, press the concealed button, the anti-theft device will take pictures of the situation in the car, and send MMS to the alarm number set. There are up to 3 answering numbers, such as group short numbers (free calls), alarm numbers (telephone listening), or other package numbers (discount calls). Once the alarm receives these numbers, it will be connected immediately (one ringtone). The user management operation of the car multimedia message anti-theft monitoring alarm requires a password, and the owner of the car can modify his own password.
