電腦彈簧機是用來生產(chǎn)彈簧的專用設(shè)備，按鍵板則是實現(xiàn)對彈簧機控制的一個人機交
互的操作界面。本文介紹了電腦彈簧機按鍵板的設(shè)計及實現(xiàn)方法。該按鍵板采用薄膜面板開關(guān)的形式，用PS/2 協(xié)議作為按鍵板和主機的通信手段，以單片機AT89S51 作為處理芯片，設(shè)計靈活，使用方便可靠，具有鎖鍵的功能，很好地滿足了工業(yè)現(xiàn)場需求。它具有的通用性使得其能廣泛應(yīng)用于以PC 機為主機的控制系統(tǒng)中。

Abstract：The CNC Spring Forming Machine is a special machine for producing springs, while key-press panel is a operating interface for controlling the spring forming machines. This paper introduces a method of designing and realizing the key-press panel for CNC Spring Forming Machines. It uses pellicle panel switch as the form, PS/2 Protocol as the communicating method,and AT89S51 as the processing unit. This key-panel has key-lock function and it is flexible and convenient for using, satisfies the requires of industry spot very well. It also can be used widely in the control systems whose host computers are PC because of its universal quality.
