Design and Development of Signal Oriented Software Platform based on ATML standard family

ATML standard family provides a new signal-oriented technical standard for ATS. This paper analyzes the four international standards in the field of automatic test: STD, ATML, SIMICA and AI-ESTATE, and systematically expounds the design and development of self-developed signal-oriented software platform CATS. Firstly, the functional composition and working principle of CATS are introduced. Then, the working principles and functional modules of TPS development platform, system management platform and TPS operation platform are analyzed. Finally, the design of signal-oriented instrument driver is introduced in detail. Engineering application shows that CATS software platform conforms to ATML standard family, and can effectively meet the requirements of avionics infield test and diagnosis. It adopts open architecture, easy to expand, and has a good application prospect.
