Hierarchical Research on Digital Testing of Process Quality Based on Communication Technology for Manufacturing Factory

Digital testing is the trend of quality testing. In this paper, the hierarchical model of digital testing for process quality is proposed, which adapter and router are used to implement communication between digital inspection equipment and computer and among computers. And three aspects of digital testing are discussed in detail including: digital testing equipment, data and information flow, and local network of digital testing. Thenceforth, this paper has also put forwards four gradual steps for digital testing research: digital tester, digital instrument, digital equipment, and digital testing unit, and some actual examples are given respectively.
