台灣本島水產養殖業常常會碰到颱風季節或豪雨情形,因雨量過多、或者氣溫瞬間變化太高或太低,而使魚類無法適應…等之影響,本研究論文針對此問題設計一具模糊控制功能之單晶PLC,應用在魚業養殖場上,由溫度控制系統、液位控制系統,對所飼養之魚群作有效之養殖管理,並促使養殖業之養殖率提昇。本研究論文以模糊理論結合單晶PLC控制系統之智慧型養殖場,以真正落實理論與實務之結合。在本研究論文之系統設計上,其研究重點是設計一具模糊控制功能之單晶PLC,可取代傳統之繼電器、計數器、計時器等組成的工業控制電路。應用模糊控制系統在魚業養殖場上,可經由溫度控制系統、液位控制系統、氧氣含氧量控制系統與餵食控制系統之偵測與控制,對所飼養之魚群作有效之養殖管理,以達到智慧型養殖場之省水、省時、省電的全自動化控制系統。本研究論文將建立一套簡單之養殖系統模型,並驗證經由模糊理論及配合單晶PLC來控制溫度控制系統、液位控制系統,使魚蝦的健康都沒問題,並大大提高農漁民之生產效率。
The environment control for aquafarmming in Taiwan is a significant issue. For example, fish are intolerable to over-raining and sudden change in temperature especially in the typhoon seasons in Taiwan. This paper proposes a single-chip programmable-logic controller integrated with a temperature-controlled system and water-level controlled system, with fuzzy control functions and efficient contribution for the rearing management in an aquafarm to promote the rearing sate in aquafarming. This paper will integrate the theory with practical techniques. The basic function of the system is to design a fuzzy-control single-chip PLC which can take place of conventional industry control circuits including relays, counter and timers. We employ the fuzzy control system in aquafarm to control the temperature control system, water-level control system, oxygen control system and feeding control system, etc. The advantages are water-saving, time-saving, and power-saving. This paper will construct a simple aquafarming model to verify our system.
