Abstract

This project describe a monitoring and controlling system using Supervisory Control & Data Acquisition (SCADA) system which can be applied to go beyond the conventional water distribution system and solving problems faced by some of the water distribution system in rural areas. The main objective is to propose a method for rural area's water distribution system by providing effective controlling and monitoring system using Scada by implementing field data interfaces device with automatic control strategies based on water flow rate and pressure using PLC. The water distribution system prototype consists of water flow sensors, 2-way solenoid valves and pumps to control the flow of water under adequate pressure in the whole centralized system. The whole control process starts when the Logic Controller (PLC) collects input signal from the water flow sensors that indicates the level of the water in the tank. PLC will act accordingly to the input signal received and send it to the valves and pumps to proceed based on the tank level, such as turning the valves on or off automatically. Scada system will detect the events that occur in the whole system, carrying out necessary analysis, and displaying the information in a logical and organized way on the PC (SCADA) in the forms of tables, graph and reports. The concept of this project aims to increase the consistency of the water flow under constant pressure by controlling the operation of the valves and pumps using PLC based SCADA in a centralized water distribution system.
