Abstract
The control based on the internet is just getting started: the first commercial projects appeared less than ten year ago but are now finding widespread application.


In this paper, we have developed the electric furnace controller for heat treatment using the internet.


The internet provides a low-cost and widely-available interface that can make teleoperated resources accessible to anyone with Web Brower.


Clients are connected the system which is electric furnace controller by using remote access watch for condition of electric furnace on real-time and it is controlled by them precisely. The system is consisted of WWW(World Wide Web) server, DB(DataBase) server, control server and controller. They are connected to the internet but the communication between control server to controller are transmitted using RS-232C.


The WWW server algorithm has been designed to include log-in function, furnace watch function, etc. The DB server has been used relational database of 2-tire structure supported SQL(Structured Query Language). And it is constituted four tables that saved process-data. The control server has been designed to base on auto-tuning method algorithm for self-controlling.


The controller that embedded in 8-bit RISCA(Reduced Instruction Set Computer Architecture) chip is consisted of distributed temperature sensing module and electric furnace driver module.


It was confirmed that the system is able to control precision temperature, ramp time and holding time for electric furnace. This controller based on the internet has a variety functions for heat treatment. The validity of these functions is confirmed experimentally.
