Abstract:With the industrial technology become more sophisticated, a wide range of washing machines in the industrial production, the development of innovative multi-functional industrial capacity washing machine a commercial use. This topic is industrial washing machines. Industrial washing machine for washing cotton, wool, chemical fiber, silk clothing, textiles, industrial washing machines is used extensively for hotels, restaurants, hospitals, schools, factories, and other areas to meet the requirements of large capacity laundry. English stands for Programmable Logic Controller, PLC, Chinese full programmable logic controller, specifically designed for applications in industrial environments. The use of PLC for the control of the core structure is reasonable and reliable testing methods, it has strong flexibility, improve the reliability of the equipment to ensure the authenticity of the design, improve labor efficiency, and achieve good economic results. In addition, the PLC can be reused, reducing the funding of test. Its flexibility, ease of handling, but also facilitate the testing at any time enter, debug, and change control procedures. PLC also has one serial interface, and easily connect with the computer, composed of the measurement and control system has brought great convenience to the maintenance and use of the system. The paper design, PLC and inverter to control the washing machine, describes the automatic washing machine control system operational requirements. Washing machine by the water, washing, drainage, dewatering and alarm to the automatic shutdown of the cycle. Design of system software, combined with the corresponding hardware connection. Has positive significance for the design, training linking theory with practice and practice capability, develop thinking and innovation capability, and to lay a certain foundation for the future in the field of industrial control.
