Abstract
The Design and Implementation of Control System of Wire-Grinding
Machine and Wire-Stripping Machine Based on PLC
Abstract
With the development of automatic control theory and PLC technology, the PLC control
technology which has the advantages of use easily, powerful function, high reliability, strong
expansion，wide applicability and the simplicity of building a control system and so on, has got a
broad application increasingly.
During the study time of graduate, the author has finished the research work of two projects
which are wire-grinding machine and wire-stripping machine. Both of the systems are based on
PLC technology. These are the backgrounds to this article which mainly discusses the application
of the PLC control technology, and the following research work is completed.
First, this article gives a overview of PLC control technology about it’s generation,
development, status quo of application at home and abroad, and the contrast with other control
technique. The source, background, status quo of research at home and abroad, significance of
research about the two projects, the control system of wire-grinding machine and wire-stripping
machine, are introduced.
Second, a method which is suited widely about the design of control system based on PLC is
covered. Starting with the structure and design principle of control system based on PLC,
analyzes the method and steps of hardware design and software design emphatically.
Third, the design which includes the overall design, hardware design and software design to
the control system of wire-grinding machine based on PLC is implemented. During the system’s
overall design, a method of multistage wire-grinding is proposed, and the theory of calculating
wire diameter is also analyzed. The selection of PLC equipment, I/O distribution, PLC wiring
diagram, the wire diameter detector, analog input module and servo amplifiers are belong to the
system’s hardware design. The software design to the system includes the design of many
modules of PLC program and many human-machine interfaces.
Fourth, the design which includes the overall design, hardware design and software design
to the control system of wire-stripping machine based on PLC is completed. To the system’s
overall design, calculating the pulse number of stepping motor is analyzed. What’s more is that
the method of speed curve like ladder controlling stepping motor is used also. The design of
hardware to the system includes the design of reducing PLC input numbers, the selection of PLC
equipment, I/O distribution, PLC wiring diagram, stepping motor and so on. The design of
software to the system is the design of PLC program which includes main routines, two
segments wire-stripping module, three segments wire-stripping module, functional pressed keys
module and the input module of digital pressed keys and so on.
Since the control system of wire-grinding machine based on PLC began to process wire, the
system which last about half and one year runs stably and reliably, and the production has a high
quality. According to the user’s identification (referring to appendix), this system’s performance
index has arrived at the same level of this kinds of products in foreign. At present, the control
system of wire-stripping machine based on PLC is in an advanced state of debugging and
development. As it is developed successfully, it will bring a great beneficial effect to the
economy.
