Research On The Transplant And Application Of The OS For The Vehicular Information Platform

In these years, with the rapid development of the economic of the country, the number of the automobiles is increasing quickly. The industry of automobile has become one of the pillar industries in the country. With the rapid development of the industry of automobile, the automobile electronics industry has also been moving forward with the giant step. And all these never leave the support of the Information Technology (IT). DingWenwu who is the deputy director of the management office for the electronic product of the Ministry of Information Industry says that the automobile electronics industry is the miniature of the information industry. Almost all the electronics and information products can be used in the all parts of an automobile. Now in the applied fields of the information technology, embedded system is that one with the fastest speed of the development, with the widest applied and with the best prospect. The development of the automobile electronics can not leave the support of the embedded technology.As the core of the vehicular controlling system, Vehicular Information Platform (VIP) is a typical Real-Time Operating System, it holds many missions such as the vehicular electronics controlling and the data communication and so on. Since there is the "system" in the name, it must do with the hardware and the software. In the embedded system, the function of hardware is always dominated by the software, particularly is the operating system (OS) that even decides the success and failure of the sales and the foreground of the market of the product. About the OS portable for the VIP is the key point of the research of this article. The main works are following:First, simple describing the function of the VIP from the angle of hardware, LPC2210 that is the 32 bits core of the ARM7 is defined the dominant CPU of the system. After that, the broaden sources RTOSμC/OS- II that is the object of transplant to the system is chosen. After making a thorough researching of the kernel of the OS and writing the start code to serving theμC/OS- II of the LPC2210, let's start transplant theμC/OS- II to the microprocessor LPC2210. The aim of transplant theμC/OS-II is that provide a stable software platform which is better for the development and the applied to the embedded system. Based on this, at first, it's the instance of an application by controlling the LM75 temperature sensor to survey the temperature to certificate the success of transplant. At last, transplant MiniGUI which is a GUI(Graphics User Interface) based on theμC/OS- II ,for improving the man-machine interactive ability of the VIP.In this article, by researching the migrating of theμC/OS- II, the applied of the LM75 temperature sensor and the migrating of the MiniGUI, ARM7+μC/0S- II + MiniGUI as an application version of the embedded system. It has a low cost, a short period of project development cycle and with the great function.
