摘要：The vehicle security system is a critical part of an
entire car system in order to prevent unauthorized access into the
car. As the statistic has shown that the number of cases of the
private car being stolen is increasing and the recovery rate is
decreasing sharply, it shows that the car security system failed to
perform to prevent unauthorized access. Most of the vehicle
security system simply consists of a few door-open detection
switches, siren, and remote control to protect the car, which
appears to be weak against experienced car theft. Therefore, the
project is carried out to develop a vehicle security system that
can measure the dynamic acceleration inside the vehicle using the
ADXL345 accelerometer and locate the coordinate of the vehicle
by using U-Blox Neo-6M GPS receiver. In order to evaluate the
performance of the proposed vehicle security system, the
experiment to determine the most suitable position among the
four places inside a car to place the device was conducted. Then,
the performance analysis of the GPS receiver for accurate
tracking also was done. The results showed that the most suitable
position to place the device is inside the center of the car
dashboard and the GPS receiver has a mean cold start-up time of
5 minutes 47 seconds and hot start-up time of 11.72 seconds, with
a standard deviation of 0.000003706° in latitude and
0.000002762° in longitude for position tracking.
