摘要
数据采集系统[1]是工业CT[1](Industrial Computed Tomography--ICT)的重要组成部分,保证数据采集系统工作的稳定、可靠和一致性,对于研制和改进其质量和提高工业CT整体性能有着重要的意义.在Windows操作系统下,程序查询的教据传输方式会因为其它程序的中断造成数据丢失,针对这一问题,对工业CT的数据采集系统进行了设计与研究[3].将程序查询方式改为中断方式,在计数逻辑电路的数据通道前端加上FIFO缓存,从而保证了数据采集和传输的可靠和稳定性.
The data acquisition system is an important part of industrial computed tomography (ICT). How to guarantee the stability, reliability and communality of data acquisition system's performance has important significance in improvement of ICT whole function. This data transmittance mode within windows will be disturbed by other program's interruption to lose the requested data. So it needs to improve the original design of ICT's data acquisition system. The data transmittance mode is shifted from program inquiring to hard interruption and FIFO cache is installed in front of data channel in order to guarantee the stability, reliability of data acquisition and trans- mittance.
