| Summary: | 碩士 === 中原大學 === 機械工程研究所 === 98 === Embedded internet system is one of the important concepts and techniques in recent development of the applications of internet system. The embedded internet systems are not only with general PC functions but also the communication function with different embedded devices. The embedded web server can be used in cross-platform systems, such as Apple PC, Mac, and PDA. Thus we use Linux-realization to form the embedded web server system to replace the web server set up by the PC workstations or large PC in traditionally. Furthermore, to improve the cable distance limitations of the traditional motor control systems, we achieved a step motor remote control system by the developed embedded system in this research.
The hardware of this research is the internal performance with full MMU (RAM processing unit) development board. The development board uses Samsung S3C2440A microprocessor with ARM920T core. Software architecture is mainly used with TCP / IP stack of Linux as the kernel of the operating system. The embedded Linux operating system can provide the functions of a general purpose personal computers, can also provide linked with networks and the expansion and change of the hardware environment, and the realization of all network applications. As Linux-embedded feature in itself and the powerful networking features and expansion capabilities, the hardware platform in this architecture will be significantly reducing costs and development time and the stability is also upgrading relatively.
This research uses the application programs such as FTP, Telnet, Boa, CGI, etc. to replace the function of PC workstation or server network to save costs and shorten development time. Furthermore, we used the supporting functions such as UDP, TCP, HTTP and other agreements to programming the more user-friendly software user interface program. The program in the remote computer is easily to understand its control mode in a short time and can make the operator to control the embedded devices and the stepping motor through the Web Server.
