Description

technical field [0001] The invention specifically relates to a variable structure intelligent interface based on a dynamically reconfigurable FPGA and a configuration method thereof, belonging to the field of electrical interfaces. Background technique [0002] The flight control system is the core part of the aircraft. It uses the flight control computer as the control core, supplemented by external controlled equipment such as sensor equipment and actuator equipment, to realize the navigation, guidance and control of the aircraft. [0003] There are many types of interfaces for the external controlled equipment of the aircraft control system, commonly used ones include RS232, RS422, CAN, 1553B, etc. At present, the traditional development method is that each type of aircraft will be customized to design and produce the flight control computer according to the selected external controlled device interface when designing the program. This traditional development method brin...

Problems solved by technology

This traditional development method brings two problems: first, the redesign and production of the flight control computer increases the time cost, which is not conducive to the rapid verification of the aircraft program; cost wasted

In addition, due to the different interface types of the selected external controlled equipment, it is impossible to provide a unified test platform, and it is impossible to conduct a quick acceptance test for the external controlled equipment provided by the cooperation unit
