Design & Application Of Embedded Remote Control System Based On Internet

With the approaching of post-PC era, the Internet accessible to embedded system is introduced to make information terminals such as household appliances, industrial equipment, more multifunctional, remote-portable and intelligent, which becomes an inevitable trend of the development of embedded systems.Based on this trend, this paper realized the remote control sx four-ten type of resistance furnace as an example of embedded Internet-based remote control system.Firstly, Internet-based remote control system embedded model is analyzed and divided into three functional modules-on-site monitoring, network transmission, remote terminal, and a number of supporting technologies, including the design of Internet access methods, the choice of embedded operating systems, the research of remote control means, and the optimization of network transmission quality is in-depth analyzed as well.Secondly, architecting hardware and software platform of on-site embedded controller is studied, focusing on the software platform, including the building of crossing-platform compiler environment, the transplanting of boot loader, the tailoring and migrating of uClinux embedded operating system and the implementing the root file system. Furthermore, the debugging technology under linux is briefly introduced..Thirdly, based on the platform of designed above, the B / S model and C / S model of application software design methods are discussed. Meanwhile, the B / S model has been deeply studied, including the establishment of embedded Web server, CGI technology, identity system design and dynamic Web page design.Finally, the resistance furnace is chosen as an embedded object to realize the design and development of remote control system.
