Abstract: This paper introduces an underlying support framework applied to a fully automatic operation (FAO) simulation test system. It mainly analyzes the principle of the framework from three aspects: communication design, component design and application design. This solution is based on distributed technology and object-oriented modeling. A reusable underlying network management module is designed, and a message division mechanism is used to design a clear division of processing components. This design has two advantages: one is to solve the problem of too many devices in FAO simulation test system and too frequent communication resulting in insufficient machine performance, and the other is to test different scenarios at the same time to improve efficiency. The application program is developed according to underlying framework, and a semi-physical simulation test system is designed and built, and the system test task of Tianjin FAO test line has been successfully completed.
