다국어 초록 (Multilingual Abstract)

The Fourth Industrial Revolution refers to the revolutionary era of convergence of Information and Communication Technology(ICT). It is the fourth important industrial era since the early industrial revolution of the 18th century. At the heart of this revolution is a new innovation in six areas: artificial intelligence, robotics, the Internet of things, unmanned vehicles (unmanned aerial vehicles, unmanned vehicles), 3D printing and nano-technology. By the Fourth Industrial Revolution, people will be free from labor because of the convenience of artificial intelligence.
Among them, Internet of Things is a technology that has various sensors and communication functions to measure environmental changes in various objects and connects to the Internet.
And it is an artificial intelligence technology that enables users connected to the Internet to send and receive various kinds of information, analyze it, and provide the learned information to the user or remotely control it. This technology will enable people to pursue a better quality of life. Objects connected to the Internet of Things must have the only IP to distinguish themselves on the Internet, and can have sensors built in for data acquisition from external environments.
Modbus is a voluntary industry standard communication protocol that is widely used worldwide for monitoring and controlling various automation equipment. Therefore, it is possible to connect with all equipment using Modbus such as ships, buildings, trains, airplanes, etc., so that environmental variables can be measured and remotely controlled. The existing Modbus has been used based on serial communication, and Modbus TCP is faster than serial communication because it uses TCP/IP based on Ethernet communication, which is the most commonly used Internet protocol today. And the use of Ethernet communication means that it can be connected to the Internet of Things, the core of the fourth industrial revolution. As a result, Modbus TCP is one of the key technologies in the fourth industrial revolution.
Countries around the world are diversifying their short- and long-term policies to ensure stable energy supply and low-carbon green growth. Of these, LEDs, which are high-efficiency, environment-friendly light sources, are an important part of national energy policy promotion. LED lighting is not only a substitute for incandescent lamps, fluorescent lamps, halogen lamps, but also can be applied to various fields such as mobile phones, automobiles, and backlight units (BLUs). In the case of Korea, the Government is making efforts to overcome the current environment and energy crisis by setting "Low Carbon Green Growth" as a representative indicator of the policy. In the 22 industries among the 6 sectors, the LED industry will be cultivated as a new growth engine industry in the 21st century. Policy, and aims to become the world's third largest LED producer in 2012.
High-power, high-brightness LED (Light Emitting Diode) is an innovative light source for lighting, and it is commercialized as an alternative light source for existing incandescent lamps and fluorescent lamps.
In this thesis, system algorithms were designed and implemented to control LED lighting using fuzzy theory and Modbus communication protocols. The input variables for an emotional lighting control system are temperature, humidity and luminance. The lighting output of an emotional lighting varies with temperature, humidity and luminance, and is derived by reflecting the color psychology to give a psychological change. As a system configuration, a controller circuit capable of LED control in wired and wireless environment was designed and implemented. This controller monitors the temperature, humidity, and illuminance status, and remotely changes the RGB value to change the LED lighting color of the controller. It also introduces a fuzzy inference system to configure a controller that can control LED lighting. And, I designed and implemented a gateway to connect the Modbus RTU which is RS485 based wired environment, and Modbus TCP which is an Ethernet based wireless environment, and manage the data by centralized management. It connects to integrated management systems, such as the ship's integrated management system and the building management system by using Modbus TCP communication. Temperature, humidity, and illumination states can be monitored and LED output values can be checked, and the user can also remotely change the RGB value, and the LED can be turned on and off in any color desired.
