스마트 양식장 수조 내 용존 산소 및 온도 제어를 위한 시스템 구현 = An Implementation of System for Control of Dissolved Oxygen and Temperature in the pools of Smart Fish Farm

다국어 초록 (Multilingual Abstract)

Dissolved oxygen, pH, and temperature are the most important factors for fish farming because they affect
fish growth and mass mortality of the fish. Therefore, fish farm workers must always check all pools on the farm, but
this is very difficult in reality. That’s why we developed a control system for smart fish farms. This system includes a
gateway, sensor gatherers, and a PC program using LabVIEW. One sensor gatherer can cover up to four pools. The
sensor gatherers are connected to the gateway in the form of a bus. For the gateway, the ATmega2560 is used as
the main processor for communication and the STM32F429 is used as a sub-processor for displaying LCD. For the
sensor gatherer, ATmega2560 is used as the main processor for communication. MQTT (Message Queuing Telemetry
Transport), RS-485, and Zigbee are used as the communication protocols in the control system. The users can control
the temperature and the dissolved oxygen using the PC program. The commands are transferred from the PC
program to the gateway through the MQTT protocol. When the gateway gets the commands, it transfers the
commands to the appropriate sensor gatherer through RS-485 and Zigbee.
