The aircraft power supply and distribution ground testing system is used to simulate the power supply, switch control status, gather and transfer the information of system in the whole life cycle. The interface between aircraft and ground test system is complex, and the interface of each project is not uniform. So the proportion of special equipment in the test system is still very high, the inheritance and the exchange of equipment is not strong, and the development cost is high. First, the basic functions and components of the testing system were introduced. Energy flow and information flow between the components are defined. Then, the typical interface circuits of power supply, control and measurement were analyzed, simplified and classified. Finally, the design of the interface of the test equipment based on the advanced back board bus architecture was proposed. The test system is developed and actual products showed that the design meet the demand in the whole life cycle test. And it had achieved product share in the two projects. This paper is a useful attempt for the investigation of the ground general test.
