Development of Test apparatus for Navigation Equipment Based on ARM and μC/OS-II

After introducing some applications of embedded technology,this paper discussed one design of an integrated apparatus for measuring navigation equipment parameter based on ARM7 and μC / OS-Ⅱ operating system.This test apparatus used a modular design approach,which was divided into several modules,namely,display and control unit,measurement unit,RF unit,audio unit,channel unit,as well as measurement and control unit which is the core of the work.They work together to achieve the whole control and data exchange.After detailed analysis of the system architecture and hardware design,the paper specifically addresses the design of the system software.The apparatus according to this design has been put in practice,and practical application shows that this test apparatus has good functionality and performance,friendly interface,stable work,and the accuracy of the test parameters fits the expected requirements.
