| Abstract: | The technologies of GPS,wireless communication and embedded system were used to design a vehicle-mounted anticollision device for cars.The ECCM of RF module was enhanced by some measures of electromagnetic shielding.In order to get the position of cars,a position judgment algorithm was presented based on the theory that a curve between two points in the range of 50 m is similar to a line seen from the earth.And based on the control of the GPS data updating,an algorithm that let wrong position broadcasting disappear was also presented to resolve the problem of broadcasting wrong position.The functions of the device meets the expected requirements by tests. |
