Design and Android Application for Monitoring System Using PLC for ICT-Integrated Fish Farm

摘要

There have been many cases of mass mortality of fish due to the power interruptions caused by natural disasters, human errors or acts of sabotage by the employees hired by rival companies, discouraging the small and medium-sized fish farmers. Thus, in this paper, a system that can monitor the power status of fish farms to cope with such situations is being proposed. The system utilizes both PLC and ICT technologies to respond to crisis. Electric power is a critical parameter for both the land-based and the water recycling fish farms. The mass mortality of fish due to natural disasters was the highest risk in the aquaculture industry. The proposed system allows immediate response for the power interruptions and consistent power monitoring by the employees. To compensate the signal transmission loss often caused by the noise power typical in the PLC-utilized models, RUDP is proposed for the transmission layer. Also, for the Android application, a graphic user interface was designed to manage overall fish farm activities, photoperiod, seawater control, Smart Aquafarm, access control, location check, withdrawal period, and secondary battery check.
