Problems solved by technology

Although the car’s existing driving assistance system has played a certain role in accident prevention and collision mitigation, there are still obvious functional deficiencies: First, when the car or its cargo is stolen, it cannot actively send an alarm message to the owner and provide the exact location of the lost car Second, it is impossible to provide the driver with a view of the front and rear blind spots of the car; third, after a collision accident, if the driver is incapacitated, he cannot actively send a message for help to the outside world and provide accurate location coordinates; Effectively detect fatigue driving and issue warnings in time; Fifth, fail to provide car occupants with on-board e-commerce and entertainment functions in addition to safe driving

Embodiment 1

[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...

Embodiment 2

[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 t...

Embodiment 3

[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 m...

Abstract

The invention discloses an embedded, mobile and intelligent interconnection drive assisting system. The system comprises a global positioning system (GPS) positioning module, a random access memory, a vibration sensor, a 3rd generation (3G) telecommunication module, a double-axle acceleration transducer, a liquid crystal touch screen, and a central processing unit which controls the vibration sensor to enter a working state, monitors and acquires vibration signals of an automobile in real time, judges whether the current automobile or goods are in a danger state, receives transverse and longitudinal automobile acceleration signals which are acquired by the double-axle acceleration transducer, judges whether the traffic accident of the current automobile occurs or not, and sends an alarm message to a number which is set by the central processing unit in advance through the 3G telecommunication module if the automobile is in danger. In the system, the advantages of all independent modules are fully exerted and organically integrated. All modules are matched cooperatively, and ensure the safety of the automobile, goods and passengers; the real-time for rescuing accident vehicles and injured persons is improved; and the system has abundant functions of electronic commerce, audio and video entertainment, and wireless Internet access, and fully improves the driving comfort.

Description

technical field [0001] The invention relates to an embedded mobile interconnected intelligent driving assistance system. Background technique [0002] With the growth of car ownership and the continuous improvement of driving speed, the frequency of car theft and collision accidents is also on the rise, and the problem of car safety needs to be solved urgently. At the same time, people's demand for driving comfort of modern cars is also increasing day by day. Therefore, driving safety and comfort have been widely valued and become the key fields of modern automobile research. Although the car’s existing driving assistance system has played a certain role in accident prevention and collision mitigation, there are still obvious functional deficiencies: First, when the car or its cargo is stolen, it cannot actively send an alarm message to the owner and provide the exact location of the lost car Second, it is impossible to provide the driver with a view of the front and rear b...
