碩士 === 中州科技大學 === 工程技術研究所 === 102 === In the fish-farming field, ambient temperature is the most essential and basic information of all environment factors. In recent years, owing to great development of electric and control technologies, numerous and distinctive automatically fish-farming systems are produced. However, those systems only provide fixed temperature control and can’t be controlled remotely. Thus, in this thesis, a remote control system with monitoring and real-time adjustment has been proposed. For the system design and implementation, this temperature control system adopts Arduino UNO R3 as main MCU platform, which collects and stores the sensing information from temperature sensors. Moreover, the proposed Fuzzy control method will adaptively adjust the cooler and heater for abnormal temperature. This thesis utilized the error between expected and sensing temperature, and the time variables of error as two inputs of proposed Fuzzy control method. Via Fuzzy theory, its output will be denoted as PWM for controlling cooler and heater. Therefore, such design is expected to achieve more efficient adjustment. The proposed thermostatic control system in this thesis will combine remote control, electrical constant temperature system and its temperature control modules. The devise completed system will attach a high accuracy and stability in beforehand.
