Automatic Washing Machine Control System Based on PLC

Abstract

In this project, a fully automatic washing machine control system based on programmable logic controller (PLC) is designed and implemented for the automation needs of household washing machines. The replacement of traditional relay control by PLC technology improves the reliability, flexibility and maintainability of the system. The system adopts Mitsubishi FX5U-64M PLC as the core controller, combined with GT Designer3 touch screen software to achieve human-computer interaction, and supports automatic control of the whole process such as washing, rinsing, and dehydration. The experimental results show that the system can automatically complete the laundry process according to the parameters set by the user (such as water level, washing times, and spinning time), and has the functions of fault alarm, status monitoring and historical data query. By optimizing the program logic and hardware configuration, the system achieves the expected goals in terms of cost, efficiency and user experience.
