Design Of Embedded Security Early Warning System For Vehicles

Embedded system is very suitable for the automotive industry, because of its small size, low power, high integration,. So it is now widely used with the development of microprocessor technology. The traditional embedded applications which are used for automobile, are limited to GPS and multimedia function, there is not so much attention paid on the security. To solve the above problems, this paper studies the existing traffic safety programs, combined with embedded systems, hoping to design a system for security early warning. The main ideas are as follows:First, the design of embedded security early warning system for vehicles was based on the important factor of the security, and combined with the characteristics of embedded system.Second, the design of hardware platform was based on S3C2410,one kind of chip belongs to ARM9. The circuit of data acquisition was designed for gathering the data of automotive sensors. For display and input,the interface circuit of touching screen was also needed to be design.Third, Linux will provide drivers and package for hardware, making hardware working in the right status. But it should be cut down and transplanted on the board,after that, it will also give the necessary support for software.At last,The graphical interface and software will start to be design when the system could be running on the hardware platform. After the design finished,it should be tested on PC before being connected with the graphical interface, then it was connected with the graphical interface by slot function. Both of the graphical interface and software was packaged into a QT compressed package, the package was transplanted into the system. That is the end of the design.The whole system will provide both visual display of The various elements of security, and a voice warning when the car is in danger. The interface is simple and friendly, and it can serve for the security very well.
