Abstract
With the improvement of living standards, the car has increasingly become the indispensable part of people, vehicle positioning and theft against technology has also become a big market demand. Due to the development of wireless technology, automobile anti-theft technology is more convenient and flexible, safe and reliable.
The system is based on the vehicle satellite positioning alarm system of GPS using DSP as the central processing unit, real-time data processing; system is mainly composed of a positioning system (GPS), real-time monitoring through satellite positioning system vehicle position, when the car speeding or resorted to setting area, system will alarm, to remind the driver driving safety; signal acquisition system, the main due to the abnormal signal is collected door abnormal opening or shock, the trunk open, abnormal sound generated by the vibration, to achieve the alarm function; alarm system, when the vehicle is abnormal, achieve sound and light alarm; control system, when the car is abnormal, the control system to control the oil supply system, realize the oil off the operation, ensure the car security; wireless communication system, the realization of remote control of the car, when the car is abnormal alarm, wireless communication system and remote alarm, remote operation and control system.
The system architecture of the vehicle positioning and theft against system and its possible, lay the foundation for a good car navigation, positioning and theft. Automobile anti-theft has extremely important research value to the car manufacturers or social insurance industry, with the development of microelectronics technology, automobile anti-theft technology has high automation, intelligent direction.
