Design of an airborne electromechanical interface unit with lightweight and extendable functions

This paper introduces a lightweight, configurable interface, bus can be cascaded expansion of the airborne electromechanical interface unit. The device is applied to the electrical control system of small and medium-sized UAV, which has the advantages of lightweight, low cost, strong versatility and extendable function. In the design of the electromechanical interface unit, the distributed processing idea applied in the large passenger aircraft is used for reference. The main feature is that the device has greater flexibility, can adapt to the interface characteristics of various sensors and actuators, and has the ability of configurable input and output interfaces and extensible bus communication nodes. The software design of the electromechanical interface unit adopts an open architecture, modular and componentized design, and the table driving technology is applied in the design, which can flexibly configure the software functions, quickly realize the function iteration of the software, and has a certain health management ability.
