[0045] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 9 and Figure 10 The shown central processing unit also receives the anti-theft command sent by the user using the remote controller through the radio frequency receiving module. When the central processing unit receives the anti-theft command, it controls the vibration sensor to enter the working state and monitors and collects the vibration signal of the car in real time. When the vibration signal is greater than the corresponding threshold When the central processing unit determines that the current vehicle or cargo is in a dangerous state, it drives the 3G communication module to send a reminder message to the number set in advance by the central processing unit. Then, the central processing unit monitors the GPS positioning coordinates, that is, monitors the longitude and latitude of the vehicle. Whether there is a change, if the coordinates change, the central processing unit determines that the current car is stolen, and then drives the 3G communication module to send the car theft alarm information to the pre-set number of the central processing unit, if the positioning coordinates do not change, and the vibration signal When it is always greater than the corresponding threshold, the central processing unit determines that the goods on the current car are stolen, so the 3G communication module is driven to send the stolen goods alarm information on the car to the number set in advance by the central processing unit. The specific implementation process is as follows: After starting the present invention, click figure 2 The "Anti-theft alarm positioning" button on the main interface shown, enter image 3 The anti-theft alarm positioning sub-interface shown. Input the alarm receiving number in the "alarm receiving number" edit box 54, such as the standard 11-digit number of China Mobile or China Unicom; input the location request number at the "location request number" edit box 55, such as the standard 11-digit number of China Mobile or China Unicom; Driver's number " edit box 56 input driver's number, as mobile or China Unicom standard 11 numbers. Click the "Complete Setting" button 57 to save the number entered in the above edit box. This number is saved in Flash36 and will not be lost when the system is closed until the next time the user manually changes the setting.

[0046] Automobile, cargo anti-theft alarm and lost car location control process in the anti-theft alarm positioning subsystem control process: After the system is started, the central processing unit (CPU) 35 first issues an instruction to drive the GPS positioning module 1 to enter the working state. The GPS positioning module 1 inputs the received satellite positioning data frame into the RAM 37 through the serial port 1 . After the central processing unit (CPU) 35 takes out the data frame, it parses it into specific longitude, latitude, vehicle speed, and time. When the driver leaves the car, the remote controller 19 is pressed to send an anti-theft command. After the command signal is decoded by the radio frequency receiving module 17, the I/O port 218 is triggered to generate an interrupt. After the central processing unit (CPU) 35 captures the interrupt, the Flash is executed. The corresponding interrupt processing program in the system drives the vibration sensor 31 to enter the working state and monitors the collected vibration signals in real time. When the vibration signal, including frequency f, amplitude A is greater than the corresponding threshold f 0 、A 0 , the central processing unit (CPU) 35 judges that the current car or goods are in a dangerous state, so the 3G communication module 3 is driven to send the first alarm message to the number set by the "driver number" edit box 56, and the content includes "Your car is vibrating abnormally + time". Then, the central processing unit (CPU) 35 monitors the GPS positioning coordinates, including longitude and latitude, whether there is a change, if the coordinates change, then the central processing unit (CPU) 35 determines that the current car is stolen, so it drives the 3G communication module 3 to " The number set by the "driver number" edit box 56 sends the second alarm message, which includes "Your car is stolen + positioning coordinates + vehicle speed + time"; if the positioning coordinates, including longitude and latitude, have not changed and the vibration signal, including frequency f. The amplitude A is always greater than the corresponding threshold f 0 、A 0 , then the central processing unit (CPU) 35 determines that the current goods are stolen, so the 3G communication module 3 is driven to send the second alarm message to the number set by the "driver number" edit box 56, and the content includes "Your goods are stolen+time ".

[0047]The central processing unit is also used to receive the vehicle lateral and longitudinal acceleration signals collected by the dual-axis acceleration sensor in real time. If any axis acceleration value collected by the dual-axis acceleration sensor is greater than the set threshold, the central processing unit determines that a traffic accident is currently occurring. , so while driving the speaker to issue a voice alarm, the LCD touch screen is controlled to issue a prompt window to cancel the alarm. The alarm sounds once every set time. Press the prompt window for canceling the alarm on the LCD touch screen, and the central processing unit drives the 3G communication module to send an alarm message to the pre-set number of the central processing unit; if the number of consecutive sounds reaches the set threshold, the user presses the LCD touch screen The prompt window of canceling the alarm on the screen does not send the alarm information, and the specific implementation process is as follows: after the system starts, the central processing unit (CPU) 35 at first sends an instruction to drive the GPS positioning module 1 and the biaxial acceleration sensor 33 to enter the working state. Wherein, the GPS positioning module 1 inputs the received satellite positioning data frame into the RAM 37 through the serial port 1, and after the central processing unit (CPU) 35 takes out the data frame, it is resolved into specific longitude, latitude, vehicle speed, and time. When a car collision occurs, if the acceleration value a of any axis collected by the biaxial acceleration sensor 33 is greater than the corresponding threshold a 0 , the central processing unit (CPU) 35 judges that a traffic accident is currently occurring, and while driving the loudspeaker 29 to send a voice alarm "Traffic accident currently occurs, do you want to cancel the alarm?", the control application software system 39 pops up a "cancel the alarm?" prompt window, The alarm sounds every 15 seconds for 1 minute. If " cancel the alarm?" button is not pressed within 1 minute, the central processing unit (CPU) 35 will drive the 3G communication module 3 to send the alarm information to the number set by the "alarm receiving number" edit box 54, and the content includes "Accident + positioning coordinates + time". If the "Cancel Alarm?" button is pressed, no alarm message will be sent.

[0048] Embodiment 2: on the basis of embodiment 1, this system can also add passive positioning control process (such as Figure 11 Shown): the central processing unit also processes the command received by the 3G communication module in the form of a short message, and when the 3G communication module receives the command in the form of a short message, it is transmitted to the central processing unit, and the central processing unit analyzes the command in the form of a short message and Processing, if the command content is to request the current position of the car, and the other party's number is a number set in advance by the central processing unit, the central processing unit will drive the 3G communication module to send a short message of the current position of the car to the number. After the car monitoring in the anti-theft alarm positioning subsystem control process and the system starts, the central processing unit (CPU) 35 at first issues instructions to drive the GPS positioning module 1 and the 3G communication module 3 to enter the working state. Wherein, the GPS positioning module 1 inputs the received satellite positioning data frame into the RAM 37 through the serial port 1, and after the central processing unit (CPU) 35 takes out the data frame, it is resolved into specific longitude, latitude, vehicle speed, and time. When the 3G communication module 3 receives a command in the form of a short message, it first encapsulates the command into data in a specific format including the content of the command and the number of the other party. Afterwards, the 3G communication module 3 triggers the serial port 2 to generate an interrupt, after the central processing unit (CPU) 35 captures the interrupt, reads the specific format data input by the serial port 2 according to the corresponding interrupt handler in the Flash36, and parses out the command from the data content and the other party's number. If the command content is to request the current position of the car, and the other party's number is the number set by the "location request number" edit box 55, the central processing unit (CPU) 35 then drives the 3G communication module 3 to send the current position note of the car to the other party's number, and the content includes "Positioning coordinates + vehicle speed + time". If the non-request automobile current position of order content or the other side's number non-" location request number " editing box 55 set numbers, central processing unit (CPU) 35 then rejects request.

[0049] The control processes in Embodiment 1 and Embodiment 2 are included in the application software system 40 in the form of programming language and stored in Flash36. The three control processes do not affect each other and can be performed simultaneously.

[0050] Embodiment 3: on the basis of embodiment 1, add overspeed warning subsystem control process (as Figure 12 Shown): The central processing unit analyzes the specific longitude, latitude, speed and time of the car through the satellite positioning data frame received by the GPS positioning module; if the speed signal is greater than the corresponding threshold, the central processing unit determines that the current car is speeding , so the speaker is driven to issue a voice alarm, and the LCD touch screen is controlled to issue a prompt window for canceling the alarm. If the vehicle speed drops below the threshold, the central processing unit controls the speaker to stop the alarm and close the prompt window until the vehicle speed is higher than the threshold again. By pressing the LCD touch screen to issue a prompt window to cancel the alarm, the alarm will be forcibly stopped. The specific process is as follows: figure 2 The "overspeed alarm" button 52 of the shown main interface defaults to the state of pressing the power-on, that is, the over-speed alarm subsystem defaults to start-up. You can close the overspeed alarm subsystem by clicking the "overspeed alarm" button to make it pop up. After the system starts, the central processing unit (CPU) 35 at first sends an instruction to drive the GPS positioning module 1 to enter the working state, and the GPS positioning module 1 inputs the received satellite positioning data frame into the RAM 37 through the serial port 1. Afterwards, the central processing unit (CPU) 35 takes out the data frame and parses it into specific longitude, latitude, vehicle speed, and time. If the vehicle speed signal υ is greater than the threshold υ 0 , the central processing unit (CPU) 35 then judges that the current automobile is overspeed, so the driver loudspeaker 29 sends a voice alarm "you are driving over the speed limit, please slow down", and controls the application software system 40 to pop up "close the alarm?" Prompt window; and below the threshold υ 0 , the central processing unit (CPU) 35 then controls the loudspeaker 29 to stop the alarm, and closes the prompt window until υ is higher than υ again 0. The above alarms can be forcibly stopped by pressing the "Shut alarms off?" button.

[0051] The above-mentioned control process is included in the application software system 40 in the form of programming language and stored in the Flash36.
