摘　　要：随着计算机技术的飞速发展,与之配套使用的键盘也被提出更高的要求,主要表现在键盘按键界面用微型显示屏替代显示内容自主可控,具有USB接口、PS2键盘接口自动识别上。市面上有诸多类型的键盘按键标识固定、不可更换,只能实现标准键盘功能。对于有特殊需求的场合,只能另定制按键上的标识。而且无法实现PS2接口和USB接口的自适应。本文设计的具有加固型键盘,通过核心控制芯片和相应的软件,突破传统按键界面固定不变的显示内容,可根据用户要求显示图案或者字符。同时集成了PS2接口和USB接口双重协议,可以自动检测识别接口类型实现自适应。加固型键盘经过加固工艺处理,在高低温、湿热、电磁干扰等恶劣环境中可以正常使用,适用于军工领域。With the rapid development of modern computer technology,the keyboard used with it has also been put forward higher requirements,which is mainly reflected in the use of micro-display to replace the display content of the keyboard key interface and the automatic recognition of USB interface and PS2 keyboard interface.There are many types of keyboard keys on the market that are fixed and cannot be replaced,and can only realize standard keyboard functions.For occasions with special needs,the logo on the button can only be customized,and it can't realize the adaptation of PS2 interface and USB interface.The keyboard designed in this paper has a reinforced keyboard.Through the core control chip and corresponding software,it breaks through the fixed display content of the traditional key interface,and can display patterns or characters according to user requirements.At the same time,PS2 interface and usb interface are integrated,which can automatically detect and identify the type of interface to achieve adaptation.The ruggedized keyboard can be normally used in harsh environments such as high and low temperature,damp and heat,electromagnetic interference,etc.after being processed by the ruggedized technology,it is applicable to the military industry.
