摘　　要：为解决图像监控设备中图像数据的实时采集与存取问题,研究了一种新型图像数据采集系统。该系统选取基于ARM7的处理器AT91SAM7XC512,运行的是μC/OS-II操作系统。当系统巡逻信号被触发时,图像可以通过串口摄像头模块采集,存储到U盘中。该设计性能好、体积小、功耗低,运行稳定可靠。系统软件和硬件已通过调试并在工业图像数据采集系统中得到了实际验证。A new type of image data acquisition system is studied for real - time picking and storage of image data in the image monitoring equipment. The system running on the operating system is μC/OS-Ⅱ and the AT91SAM7XCS12 is selected as CPU chip which bases on ARM7. When the patrol signal is triggered, the image is input from the serial captures image model, which stores to hardware by USR. This design is not only of real time capability, but also with small volume and low - power consumption, and has a steady and reliable function. The software and hardware of this system have passed the debugging and is validated in an industrial image data acquisition system.
