Study on web-based network electrical machine control

Electrical machine control is the essential technology in motion control field. Electrical machine is adding the network communication module in their traditional control unit, while motion control is stretching its way toward remote motion control domain. The Web-based network motion control is really a way to develop remote motion control in an open area; it gives more chances to operate and update the motion control equipments far from the workshop. The author aims at applying an extending network communication module to the traditional electrical machine control unit and some special problems aroused from making use of J2EE Platform technology in electrical machine control, such as the interface between software and control unit of electrical machine control, and the server of the remote electrical machine control. In this paper a subminiature permanent DC motor is connected to the server via RS232 serial port and is also used as an object for remote control, the author present the difficulties in building the B/S (Browser/Server) structure which can operate the electric machine through the Internet far from our lab, and gives some possible ways and some novel ideal to solve the problem
