【摘要】 数据采集系统的计数逻辑是工业计算机断层扫描成像(Industrial Computed Tomography--简称工业CT)的重要组成部分。如何能够保证数据采集系统的控制逻辑工作的稳定、可靠和一致性,对于研制工业CT,提高工业CT的整体性能有重要的意义。如何实时采集、存储这些庞大的数据是工业CT要解决的重要问题之一,这涉及到总线、采集与存储、设备驱动程序、系统级软件设计等关键技术。介绍了工业CT数据采集系统计数逻辑的设计方法,详细论述了数据采集系统计数逻辑的总体设计和具体设计,给出了系统的设计与实现方案。更多还原

【Abstract】 The logical circuit of counter of data acquisition is an important part of ICT (industrial computed tomography). How to guarantee the stability, reliability and communality of logical circuit of counter of data acquisition system’s performance has significance in improvement of ICT whole function. The problem about how to get and process the large image data is very important to the technology of ICT. It is associated with BUS technology, developing in the kernel model of operating systems and programming in the system level, etc. The architecture of control logical circuit of data acquisition of ICT is discussed. The design and realization of logical circuit of counter of data acquisition are discussed in detail.更多还原
