針對(duì)目前使用的RS232接口數(shù)字化B超鍵盤(pán)存在PC主機(jī)啟動(dòng)時(shí)不能設(shè)置BIOS,提出一種PS2鍵盤(pán)的設(shè)計(jì)方法。基于W78E052D單片機(jī),采用8通道串行A/D轉(zhuǎn)換器設(shè)計(jì)了8個(gè)TGC電位器信息采集電路,電位器位置信息以鍵盤(pán)掃描碼序列形式發(fā)送,正交編碼器信號(hào)通過(guò)XC9536XL轉(zhuǎn)換為單片機(jī)可接收的中斷信號(hào),軟件接收到中斷信息后等效處理成按鍵。結(jié)果表明,在滿足開(kāi)機(jī)可設(shè)置BIOS同時(shí),又可實(shí)現(xiàn)超聲特有功能,不需要專(zhuān)門(mén)設(shè)計(jì)驅(qū)動(dòng)程序,接口簡(jiǎn)單,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.

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.
