Development of Wireless Remote Water Drainage Control System Using Programmable Logic Controller

Korea is classified as one of the OECD countries subjected to poor water management conditions. Owing to the country s small land area and high population density, there is a large amount of water but a scarcity of water supplies. In June 2018, the Basic Act on Water was promulgated, outlining key values and goals, such as public nature, sustainability, safety, equity, efficiency, democracy, and accountability. The aim of this study is to develop a wireless remote water supply control system using a programmable logic controller (PLC) to create an automatic control system that can be used to manage water effectively. The configuration of the device was classified into PLC, control, touchscreen, and pumping devices. The touch screens were configured in the main screen, manual control screen, and automatic control screen modes. The PLC and the touchscreen communicated using RS232. Through the development of this device, convergence technologies, such as sequence control, PLC programming, and communication interfaces, can be acquired, and the actual products can be easily controlled using touch screens.
