摘　　要：工业ＰＣ一般都有标准１０１键键盘接口，但大多数工业ＰＣ使用的是非标准、非编码键盘。因此开发一种既能通过标准ＰＣ键盘接口与工业ＰＣ通信，又能驱动非标准键盘的通信接。是十分有意义的。本文给出了一种用８０５１单片机实现上述接口的方法。Industrial computers have the standard interface with the 101-key keyboard, but most of them usenon-standard. non-coded keyboards. So it is valuable to develop a kind of communication interfacewhich can not only communicate with industrial computers through the standard PC keyboardinterface but also drive non-standard keyboards. In this paper a kind of such interface realized with8051 is introduced.
