中文摘要：

以在ARM9硬件平台上实现充电电池荷电状态检测为背景，详细介绍了在嵌入式系统中的设计与实现。该系统硬件搭建以S3C2440ARM920T处理器为核心芯片。软件搭建以SQLite嵌入式数据库为数据存储、筛选、分析和处理核心，通过对$3C2440内部ADC编程获取波形数据，采用Qt／Embedded实现图形及人机界面显示，最后提出了进一步完善系统检测功能问题的解决方法。

英文摘要：

A battery detection system of state of charge based on ARM9 was designed. In this system, $3C2440 ARM920T processor was chosen as the core of hardware, SQLite database was chosen as the core for data saving, sieving, analysis and processing. The waveform data were received by writing procedure to the ADC in S3C2440, the sketch and man-machine interface manifestation was realized by Qt/Embedded. In the end, some methods were put forward, which could solve the question of detection.
