Study Of The Remote Supervision System Based On Ethernet And Wireless Network

The majority of embedded systems are used independently in industry controlling fields, and many embedded systems are not connected to Internet. Actually, remote supervision system comes at the right time to meet people's need because many companies want to control and manage devices not only from local places but also from remote places. A lot of enterprises pay attention to the information of company management and efficiency is becoming more and more important. The remote supervision system meets people's need and it's really of great significance.Embedded system is based on application-centered hardware design and software development facing application. Embedded system is widely applied in such areas as manufacture, process control, communication, instrument, and consumer product. The development of Internet is causing the demand of integration of embedded and Internet.Linux comes out from 1991, it has developed into powerful and perfect operating systems in a short period of about 16 years. Linux will be available in many hardware platforms. uClinux is a branch of Linux, it is designed for the CPUs without MMU(Memory Management Uint).At first the paper introduces the framework, function and developing trend of remote supervision system, then analyzes the present remote supervision system in detail. Secondly, based on detailed analysis of system development platform, the paper finished the hardware and software design of S3C44B0X and embedded uClinux development system independently. As for hardware design, the detailed construction of every hardware component is given. As for the software design, the configuration and compilation of standard uClinux are described in detail. This paper introduces one application—embedded web server, the database—MiniSQL is also discussed in this paper. Eventually, the software and hardware of remote supervision system based on S3C44B0X and uClinux are completed. The remote supervision system is used in smart home system in the lab at the last part of this paper.
