ABSTRACT
For the efficient working of the paper cutter machine, the good control system is the key techniques. In the thesis, a paper cutter machine distributed control system based on AT89C52 controlling the stepping motor is described It includes overall planning system design, hardware and software design, etc.
Firstly, this thesis introduces the current conditions and trends of paper cutter machine .Secondly, introducing study on mechanical structure of the paper cutter machine, the work principle is introduced.
This thesis introduce a system based on AT89C52 is described, the signal from AT89C52 controls the stepping motor and LCD display circuit. The data can be input with keyboard，and stepping motor is controlled by these date, and the paper cutter machine state can be showed by the LCD display. The LCD monitors is driver by the LCD driver HT1621B, and the descriptions of the HT1621B Drivers role are detailed. The design is written in assembly language source code, part of the modular software design, by the three main modules: system monitoring module, keyboard scanning and processing, display program modules.
