A Design Of Universal Remote Interface Unit Of Airborne Electromechanical System Based On FPGA

The development direction of aviation electromechanical system management is airborneelectromechanical integration. Universal interface technology for terminal equipment is one of thenecessary conditions to improve universality of the device. This paper analyzed the domestic andforeign present situation of airborne terminal interface technology, and proposed a design of universalremote interface unit of airborne electromechanical system based on FPGA. The main content of thepaper is about the overall scheme of the remote terminal, hardware and software design of the system.To improve universality of the interface, this paper introduced application methods of the dynamicreconfiguration technology and switch matrix technology in universal remote interface unit. At last,the author promved her ideas by some examinations on a simulation platform of airborneelectromechanical system.Through the analysis of signal characteristics of airborne electromechanical system, the overallscheme of the remote interface unit was proposed based on the study of abroad LRU/LRM. Chipselection of hardware system and design of the interface circuits and control circuits were introduceddetailly. The system software was divided into a series of small modules according to the rule ofmodularity. Many kinds of ways were used to realize module functions, such as the combinationallogic circuit, the state machine and the IP core provided by Xilinx Com.According to the earlier achievements and author’s reseach on the dynamic reconfigurationtechnology, the concrete implementation method for engineering application was described. EAPRdesign process under ISE12.2environment, dynamic invocation process of IP core and PIN grammarof signal communication between static module and dynamic module were discussed in this paper.The application of dynamic reconfiguration technology in airborne electromechanical system wasintroduced in details.The research of this paper is meaningful. The design method of universal remote interface unitprovides certain reference for interface technology of terminal equipments of airborneelectromechanical system. And the engineering application method of dynamic reconfigurationtechnology also has practical implications.
