PLC를 이용한 냉풍기 제어 장치 개발

Development of a Chilly Wind Control Equipment from PLC

The purpose of this paper is to develop an automatic equipment utilizing PLC. This tool is divided into four parts: PLC, a brain center, a touch screen, and a chilly wind machine. The touch screen contains a main mode and a power supply control mode. Buttons for START/STOP and lamps for operared condition are shown in the main mode. All switches are set up to press the button once (to turn on) and once again (to turn off). The power supply control mode is equipped with power supply, air-conditioning, reservation, and rotation. PLC and the touch screen are able to communicate with each other through RS232. From this automatic equipment utilizing PLC, fusion techniques will be acquired such as a paint touch screen, PLC programming, a sequence control, and a communication interface. Also, most products for our daily life could be easily managed with the touch screen.
