摘要
针对电气工程师需要查询大量技术资料和公式以及测量电气参数等问题,对电气工程师PDA进行了研制,该PDA硬件采用ARM核微处理器、数据采集与处理电路和触摸屏/LCD显示电路。通过对现有嵌入式数据库的分析和研究,采用了嵌入式数据库SQLite,并移植到嵌入式微处理器S3C2440和Linux系统中。根据电气工程师PDA的功能,设计了波形存储表、电参数测量记录表、电学公式表和电气资料查询表,重点对电气工程师PDA数据表及其字段、电学技术资料查询模块数据库表的建立和电气资料查询模块中数据库查询程序设计进行了分析。通过在嵌入式微处理器上移植Linux操作系统和SQLite数据库进行电气工程师PDA的应用软件设计,实现了在线计算、编辑和查询电气资料的功能,圆满地完成了该PDA的设计要求。
The electrical engineer PDA was developed for solving electrical engineers need to look tor a lot of technical information, edit formulas, measure electrical parameters, and so on. The PDA hardware is made up of ARM core microprocessor, data acquisition and processing circuit, and touch screen / LCD display circuit. The embedded database SQLite is used and transplanted to the embedded microprocessorS3C2440 and Linux systems on the basis of the existing embedded databases are analyzed. Waveform storage table, electrical parameter measurement record table and electronic formulas table are designed based on the function of electrical engineers PDA. The PDA data sheet＇ s field, electrical technical data query module database table creation and database design of electrical data query module are mainly analyzed. Linux operating systems and SQLite database are transplanted to the embedded microprocessor, electrical engineers PDA application software is designed, and online calculation, editing and querying electrical data, etc are realized. The design request of this PDA was successfully completed.
