DESIGN OF CONTROL SYSTEM FOR REMOTE CONTROL SYSTEM USING INTERNET

摘要

The Internet when you want to use such production sites and industrial facilities, and it is common to conventional devices using a protocol converter does not support TCP / IP, see the general connection structure using these converters client (Client) - Internet network - it consists of a device-to-server (server) - protocol converter control panel. Haejugo server to connect the computer and the Internet network to remotely control the system, a protocol converter is responsible for connection to communicate with each other located between the server and the control panel. Converter and the controller is usually between RS-232C, the control unit half and are connected to the RS-232 communication. In such a connection structure, to control the plant to facilitate one individual is, to an integrated management and the need for a separate operation, difficult to multi-user use. Thus the additional equipment was required to integrate systems management via the Internet until now, there is a limitation due to the cost and maintenance issues that apply to the workplace of small and medium scale. In the present invention, by integrating the various management systems that are used on-site at a low cost and suggests ways in multi-use it is made possible, and invented a control apparatus for a remote control system based on the Internet.
