Design And Implementation Of Vehicle Terminal-Mode’s Client Based On VNC

With the development of auto industry and electronic technology, the vehicle information platform has become the new trend of modern vehicle development.At the same time, mobile phones, from basic voice telephony functions, developed to set a variety of infotainment services in the smart phone. How to make drivers and passengers seamless connect and display through the touch screen of vehicle information systems and control of mobile phone applications, and vigorously promote the availability of the telephone, navigation, social activities, and music and other car services. Therefore, this paper is based on the VNC system of remote control car terminal-mode’s client in order to achieve the seamless connection of the smart phone and the vehicle information system.Firstly, through the vehicle terminal models and related technology development status, this paper combines with the functional requirements and the overall structure of the vehicle terminal-mode’s client and describes the design ideas of this terminal-mode’s client. In order to make the terminal-mode’s client endpoint automaticlly search and found the service equipment, this terminal-mode’s client is designed according to the protocol of UPnP technology, automatically find the phone service equipment. By managing the available equipment, the terminal-mode’s client can support multiple terminal-mode’s server. In order to have a better compatibility, this terminal-mode’s client alse use the RFB protocol exchange data with the service in the realization, and in accordance with the requirements in the agreement, also complete the Des encryption algorithm. In order to achieve a better performance of the terminal-mode’s client, through analysing the process of the VNC remote control system’s client, this paper designs and realizes the process of this terminal-mode’s client, it has improved the efficiency of client’s receiving data. On the remote desktop graphics rendering, this client draws the mobile desktop with GTK drawing tools. At the same time, this paper has done some research on remote operation of mobile phones including virtual keys,and realization.Finally, this paper gives this terminal-mode’s client all sorts of function test results, through the test, they show that this terminal-mode’s client is scalability, safety, strong compatibility, and convenient operation. And also this paper put forward this terminal-mode’s client deficiencies and prospected.
