摘要
介绍嵌入式系统的DIS应用,分析DIS的一般模型,设计并实现了其主体部分的软硬件。硬件以ARM7核微控制器AT91SAM7SE512为核心,包括A/D转换、带触摸屏的液晶显示、ZigBee无线连接、数据存储等多个组成部分;软件采用μC/OS-Ⅱ实时操作系统,移植了FAT文件系统和图形用户界面。经测试,系统性能稳定,操作简便。
The embedded system application in DIS and the general model of DIS are introduced. The main parts of DIS are designed and implemented. It equips AT91SAM7SE512 as its main controller, contains many other components such as AD converter, LCD display with touch screen, ZigBee wireless, data storage device, etc. It utilizes μC/OS-Ⅱ real -time operating system,transplants FAT file system and graphical user interface. The data acquisition system has stable performance, and is easy to use.
