Based On Gprs Gps Vehicle Terminal

Recently,great advance has been achieved both in computer science and electronic technology,which makes the modern automobiles much more intelligent and much more comfortable.With more and more network technique applied in embedded system and the great improvement in semiconductor manufacturing,the EMPU(Embedded Micro-Processing Unit) has extended its application to the automobile industry.The embedded technique gives the best solution for automobile electronics and makes it possible to produce high performance terminal for cars at low cost.Nowadays,wireless data transition technology has brought great fortune for business especially for the information acquisition system,which could extend the data acquisition range and cut down the maintenance cost.The technique of vehicle supervision can guide the motor to it s destination conveniently, quickly and rightly,which is very important in increasing the transportation efficiency and energy saving.Today,the latest GPS,GSM,GIS techniques have been applied in motor fields.This paper discusses the Vehicles Managing Navigation System of GSPRS,GPS based on MEGA128,taking MEGA 128 as the car of central microprocessor in vehicle monitoring terminal and using long range supervision center as comprehensive system resolvement.The vehicle monitoring terminal positions the vehicles through GPS module,delivering the position,appearance information to the long range supervising and controlling center through GPRS.GSM module controlled by microprocessor,and sending out the controlling information analyzed after combine the GIS information the system.Center assistant can setup Calling Response or Self-determination Response for the car according to the operational Process.At the end of the dissertation,a summary was made.Some possible promotions were also given at the same time.This intelligent vehicle terminal has compact structure and powerful function such as car location and tracking.The system was economical and easily for upgrading.
