Design Of Embedded Automobile Navigation And Security System Based On ARM9

With the rapid development of computer technology and satellite navigation technology,vehicle embedded navigation system has become the focus of vehicle industry development.Vehicle navigation system is a kind of system combined with global positioning technology,communication technology and embedded technology, which can supply real-time and rapid navigation positioning information for driver,and it is adapt to automatic positioning of vehicle and ship.In our country,the consumption of vehicle become more and more heated,the numbers of private vehicle also become larger and larger,on the other hand,case of stealing vehicle keeps up,which bring about giant loss.So,automobile positioning and security also become a great need of the market.Research on the automobile intelligent system has an important significance.The development of general packet radio service and global positioning system technology supply a kind of technology support for the vehicle positioning and security. GPS as the means of positioning and GPRS as the way of wireless communication, based on ARM9 process unit and Linux embedded operation system,this design develops automobile navigation and security system based on ARM9.Different from former vehicle embedded system,according to the intended function,this design include two different function models of driving and security,realize the joint of automobile navigation and security.Based on above idea,this design firstly analyze the condition of research on automobile embedded navigation and security system and its development in national wide and foreign country,in addition,make analysis on basic theory of embedded technology,GPS and GPRS.And then,put forwards the general design program of the system,introduce the composition of hardware and software,describe its concrete design and realization in detail,analyze the key technology,also give the solution of it. At last,make test and adjust against this system,the result proves that the designed system in this paper work steadily,can realize the function of automobile navigation and security and achieve the fLxed object.
