Embedded Design Of Networked Supervisory System Based On WINBOND W90N740 ARM7

With the rapid development of computer communication and large scale circuit, internet becomes a trend in society, especially in the area of supervisory System. Depending on the Internet, supervisory system can acquire and control signal from one place to more place of a city, from one city to more city and even in any place in the earth. So realization of network in supervisory system has very important significance. However we can not ignore the network's stabilization. The Embedded Operating System can do it well. uClinux is a branch of Linux2. 0/2. 4. It is running on many kinds of hardware platform. uClinux also owns other merits such as its free source code, its inherit network functions and its modularization design in kernel. Therefore uclinux is very suitable to be the operating system of embedded system especially in control area.In this dissertation, the system design of Networked Supervisory System based on WINBOND W90N740 ARM7 chip, is discussed in detail. The mainly design include the design of Hardware, debugging of embedded OS , device driver coding, application coding and debugging. The content of chapters is as below:Charpter1 is introduction. The Supervisory System and the Embedded System are discussed.Charpter2 is the design plan of Networked Supervisory System based on Embedded Operating System. The system structure of the whole system is discussed. In addition, the main nature of the networked supervisory module is also introduced.Charpter3 is the Building of Networked Supervisory System based on Embedded Operating System. It is divided into hardware and software design. The hardware design include the design of embedded processor ARM and its of chip device. The software design include the development of the device driver.Chapter4 is the realization of Networked Supervisory System. The development of application program is discussed here.Chapter5 is the testing result and applying of Networked Supervisory System completed.Charpter6 is a sum up and prospect of the dissertation. The function of this system has realizede. The improvement of it is also discussed.The Networked Supervisor System based on Embedded Operating System has been successfully developed. The research include the development of the hardware platform based on ARM, porting uClinux on hardware platform, implementing of real-time support of kernel and the development of the device driver. This Network Supervisory System has the characters of low cost, low power consumption, small bulk and more function.
