Design of the Wire Rope Cleaning and Detection Line Control System Based on Touch Screen and PLC

Abstract:

This paper puts forth an overall plan of integrated control system based on PLC and touch screen according to the technological requirements of wire ropes cleaning and detection line. It introduces an automation control system composed of two parts by touch screen and PLC automation control system. The core of the control system is the PLC which uses I/O to achieve the control of the switch. Touch screen communicates with PLC by means of RS232 to complete all parameters input and actuators operations. First, it designs various modules of the hardware circuit according to the general scheme. PLC controls rough brush motor, high-pressure water cleaning motor, water drying valve, oil drying valve through I/O module. PLC controls take-up motor by D/A output module. It uses temperature controller to realize automatic heating control in the process of water heating and oil heating. At the same time the temperature controller communicates with PLC by means of RS485. Then, it designs the software of PLC control system which adopts the idea of modular design. As to the software of PLC control system, many programs are designed such as manual control function, automatic control function, communicating function and so on. Finally, it designs the Human Machine Interface system which completes many functions such as manual control operation, automatic control operation, parameter setting, system diagnosis, historical records and help system. The system makes the automation and intellectualization to be realized. It can monitor parameters real-time and improves production efficiency.
