基于多线程的惯导逻辑仿真器设计
Design of Inertial Navigation Logic Simulator Based on Multi-thread
摘要
Abstract
Inertia Navigation System( INS) can not output dynamic data when plane is not moving. Simulation of INS can solve this problem. In the avionic system simulation, the inertial navigation logic simulator interconnects to bus controller and other avionic or non-avionic subsystem using 1553B bus. It receives exterior incentive data through Ethernet. Using multi-thread can make main INS and backup INS operate respectively. The structure of hardware and the design of software is expatiated. After establishing flight attitude model and navigation position model,the simulator can simulate different kinds of logic sub-process of INS. The test and debug of avionic simulation system proves that, this simulator can receive flight information and fault state from exterior incentive source by rule and line,send position data and pose data of the plane to bus controller periodically after resolving,execute INS logic in the avionic detail design document and send INS state to bus controller.关键词
