Abstract:The developing process of the 1553B bus in aerospace area, especially in servo test area, is introduced. The common questions usually met in the development of servo test software systems based on the 1553B bus are also discussed. More, an efficient and strong application architecture for solving the 1553B bus BC part realization in servo test area is discussed in detail, The solution based on the architecture is the universal servo test class library based on the C++ language. The class library is so stable and reliable that it has been used in so much critical tests of many research types in recent ten years. It has been the base solution for the 1553B bus application in servo test area. It also provides an reference significance for the modularization, universalization and production of servo test software systems.
