The logical design of data acquisition is an important part of industrial computed tomography (ICT). How to guarantee the stability, reliability and communality of logical design of data acquisition system performance has significance in improvement of ICT whole function. This data transmittance mode within Windows will be disturbed by other program's interruption and lost the requested data. So it needs to improve the original design of ICT's data acquisition system. The authors shift the data transmittance mode from program inquiring to hard interruption and install FIFO (first in first out) cache in front of data channel in order to guarantee the stability, reliability of data acquisition and transmittance. In this paper, the authors discuss the architecture of logical circuit of data acquisition of ICT, the design of the model, then the authors discuss the design and realization of logical circuit of data acquisition of ICT in detail
