| Summary: | 碩士 === 國立彰化師範大學 === 工業教育與技術學系 === 102 === At present aquaculture cost of human resources over high which require lengthy inspection and measure water quality. Medicine, waterwheel and heater must all be manually started. If aquaculture encounters bad weather situations which are very difficult to stable environment, negligence can make huge economic losses, to reduce labor costs and increase the stability of the water quality, aquaculture will use automation to replace human. This thesis system includes programmable logic controller and Visual Basic programming software. Based on programmable logic controller connected sensors, medicine machine, waterwheel and heater, and then start by fuzzy control making fish farms water pH, dissolved oxygen, temperature to achieve the set target, the same time to hold the latest status of fish farms environment from a remote monitoring system. In such status, fish farms can achieve the most perfect environment to reduce labor, enlarge production management, improve product quality, promote industrial upgrading and enhance the competitiveness of the export of fishery. In addition, the system to aid anti-theft function which contains a microcontroller circuit module, g-sensor and wireless transmission interfaces to accomplish the anti-theft function.
