The development and application of intelligent integrated demonstration system based on RS232 interface
Abstract
The airborne distribution system is a general name for subsystems that ensure the flight security, it is the fundamental guarantee for the safety of aviation. Stringent demand is needed owing to the development tendency of airborne distribution systems towards integration and intelligence, which brings a growing development risk and increasing technical difficulty. In order to reduce the risk and improve the quality, it has become necessary to carry out simulation experiment in the system development procedure with the application of the semi physical simulation technology.
The topic of this paper is based on a certain aircraft intelligent power distribution system simulation test . To meet the simulation test task demands of the distribution system, this paper proposes a method to set up an emulator of mechanical and electrical subsystem with the application of Virtual Instrument, whose hardware core is the National Instrument PXI industrial computer. To validate the function of the distribution management system monitoring and control each subsystem of distribution subsystems, the emulator of distribution subsystem completely replace the actual hardware of the distribution subsystems to provide simulation incentive to the electromechanical management system.
In the paper, the research background and significance of the intelligent power distribution system integration demonstration is briefly described. Then this paper analyses the research status and the development tendency to complete the simulation test with the application of Virtual Instrument in aerospace field in the domestic and overseas, introduces the concept, features and advantages of the Virtual Instrument and LabVIEW. And a detailed analysis of the electromechanical management system simulation test task requirement determined intelligent power distribution system integration demonstration design scheme. This paper describes the emulator of mechanical and electrical subsystem hardware connection and software implementation process in detail. Followed by a detailed description of the intelligent distribution integrated presentation system software implementation process. The software development platform of the intelligent power distribution system integration demonstration is the graphical programming development environment LabVIEW developed by the National Instrument.
The intelligent power distribution system integration demonstration accomplished in this paper has been applied to the simulation test of a certain aircraft electromechanical system of an Aircraft Design and Research Institute, its functional and technical specifications in line with the practical application, and achieved good results.
