Development of The Automatic Control System Based on Human Machine Interface

摘要

The development of the industrial automation technology has led to the control system based on human machine interface (HMI) that allows the monitoring system by the user. Automatic control based on HMI emphasizes monitoring techniques in real time for the plant's performance through the monitor screen or LCD. This paper presents the design of automatic control system based on HMI to increase the user convenience while controlling the plant. This study finds a solution about the automatic control system based on HMI for monitoring a plant's performance remotely using the LCD screen, so it can help and facilitate the user, particularly by the features: (1) enable to monitor a plant condition through visualization of the real time status, (2) controlling the values of plant's parameter remotely. This study uses a research and development method, which each stage of the sub-systems will be assisted for improving the overall system's performance so can obtain in accordance with the desired system. The results show that the developed system can perform to select objects based on the object's color, those are red, white and silver. Also it can distinguish the workpiece of metal and non-metal. All processes of the object selection can be monitored through the monitor's screen.
