The Research And Design Of The Embeded WEB Systeme Of Achieve Telecontrol

With the common use of optical fiberinternet communicating system in the universities ,the teaching ways are gradually connecting with the internet system. In order to meet the needs of universities, the experimental teaching instrument company has begun to develop the internet intellectual equipment so that it can realize the transmission of internet.communication and information. Internet intellectual experiment is divided into different subjects. To realize internet intellectual function, there are export signals, middle changeable signals,electric pressure and electric current ect.of part experimental elctric road to collect on the experimental platform. Statistics collecting fuction will be completed by only one collecting board and it has COM port (RS232 or RS485) .Nowadays, to make the collecting board and internet communication, domestic enterprises of teaching instruments all use PC as media, that is, collecting board-PC-internet connecting ways, directly raise the cost of system intrument, waste Pcresources, for PC is not necessary instrument in the experiment. Because of hard work in PC pperating system and mending of experimental software, experimental managers are found to be caused a great pressure, paradox existed can be solved if Embeded System takes place of PC, the collecting ways of board–equipment-internet have a lot of problems settled, including long distance contral being done in experimental equipment.Experimental equipment and internet are interaction, which not only transfer instant collectting statistics, but send control order to experimental equipment by longdistance PC. In this way, the developing of Embeded System must ensure longdistance PC interview acting interaction Interaction interface resulting in realizing watch and control to experimental platform state Embeded System connecting internet. The main problems lie in how to deal with the internet communicating. In this subject, simple Ethernet transfer agreement(TCP/IP line)has been adopted in AT89S52 Single Chip Micyoco programm, even realizing transmission of link layer by Ethernet controller. Be lacking of PC operating platform, Interaction interface turn to Single Chip Micyoco recognizing AscII code after with HTML format compiltion , it is stored in Single Chip Micyoco inserting Ipaddress iln longdistance PC exploring equipment will interwiew this Interaction interface.This article has detailed illustrated the process in analyzing problems, choices of settling methods. Divices of system structure ,hard and software realizing progress,etc. it got expected result by adjusting internet system. The mode that run the experimental platform statistics collecting board cut-over Ethernet send operate convenient. It has charaters of transmit rate high, price reasonable, and common use. It can be used the same system in the intellectual experimental platform of different subjects, meanwhile, software should be adjusted a bit, symlyfying the development process of Embeded WEB servicer hardware. The most important thing is that producting enterprises can ask each experimental platform through Browser in simple asking way, carrying on instant longdistance analyzing directing users or teachers to have it repaired in time. It is a good way to solve increasing internet intellectual experimental platfore and services.
