Abstract

Modbus is a serial communications protocol, it has since become a practically standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices. Therefore, it can be connected with all devices using Modbus protocol to the measurement and remote control on the ships, buildings, trains, airplanes and etc.. In this paper, we add the Modbus communication protocol to the existing lighting controller sensitivity to enable verification and remote control by external environmental factors, and also introduces a fuzzy inference system was configured by external environmental factors to control LED lighting. External environmental factors of temperature, humidity, illuminance value represented by the LED through a fuzzy control algorithm, the values accepted by the controller through the sensor. Modbus is using the RS485 Serial communication with other devices connected to the temperature, humidity, illumination and LED output status check is possible. In addition, the remote user is changed to enable it is possible to change the RGB values in the desired color change. Produced was confirmed that the LED controller output is based on the temperature, humidity and illumination.

Modbus는 각종 자동화 장비 감시 및 제어에 전 세계적으로 널리 사용되고 있는 자발적 산업표준 통신 프로토콜이다. 그러므로 선박, 빌딩, 기차, 비행기 등 Modbus를 이용하는 모든 장비들과 연결이 가능하여 환경변수의 측정 및 원격제어가 가능하게 된다. 본 논문에서는 퍼지제어 시스템을 이용하여 외부환경요인을 각각 조합한 불확실한 내용을 정량적인 값으로 변환하여 LED 조명으로 표현하기 위해 알고리즘을 설계하고, 설계한 알고리즘에 Modbus 통신 프로토콜을 추가하여 선박의 통합관리 시스템에서 외부환경요인 확인 및 원격제어가 가능한 감성조명용 LED 제어기 회로를 설계 및 구현 하였다. 외부환경요소인 온도, 습도, 조도 값을 센서를 통해 제어기로 받아들이고 이 값들을 퍼지제어 알고리즘을 통해 LED로 표현된다. Modbus는 Serial 통신으로 RS485를 이용하여 다른 기기와 연결 되어 온도, 습도, 조도 상태 및 LED 출력 값 확인이 가능하고 또한 사용자가 원격으로 RGB 값을 변경 할 수 있기 때문에 원하는 색으로 변경이 가능하게 된다. 제작한 제어기로 온도, 습도, 조도에 따라 LED 조명색상이 변화 되는 것을 확인 하였다.
