针对目前使用的RS232接口数字化B超键盘存在PC主机启动时不能设置BIOS，提出一种PS2键盘的设计方法。基于W78E052D单片机，采用8通道串行A/D转换器设计了8个TGC电位器信息采集电路，电位器位置信息以键盘扫描码序列形式发送，正交编码器信号通过XC9536XL转换为单片机可接收的中断信号，软件接收到中断信息后等效处理成按键。结果表明，在满足开机可设置BIOS同时，又可实现超声特有功能，不需要专门设计驱动程序，接口简单，成本低。 Abstract: Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot， this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller，designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter， potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU， software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot， ultrasound specific functionality can be achieved at the same time， it does not require specially designed driver，the interface is simple and low cost.
