다중 유압실린더 동조제어시스템을 위한 원격제어 및 모니터링

Abstract

In order to execute position synchronizing control of multiple hydraulic cylinders which are positioned in wide area and have a large number of low-level components, not only a position synchronizing control system must be established and but also a remote control and monitoring system must be established in view of hardware and software.

In this paper, two methods comprising an exclusive control network are suggested. One is a method using Fieldbus based on RS-485 network and the other is using TCP/IP based on LAN. In order for control system designer to get an exact information in establishing a control network, a large amount of concrete contents is surveyed.

For the purpose of remote control and monitoring of position synchronizing control system, comprising methods of a remote control and monitoring system are suggested. Especially, control and monitoring pages in capable of using TCP/IP socket communication program are developed.

In order to test the possibility of real time control and monitoring, two kinds of experiments are executed. One is an experiment for Modbus ASCII protocol based on RS-485 network and the other is an experiment for TCP/IP based on LAN. In the conclusion, the possibilities of remote control and monitoring are verified.
