【摘要】 为对新机各分部件功能及性能的测试做到准确无误,需要协助设计人员最大化地测试每一个瞬间,在飞行仿真平台上提出更高的仿真精度需求,包括以1 ms仿真周期完成飞行仿真模型的实时解算,同时采集与存储5 000个仿真实验数据的需求。实验结果表明,采用紧凑采集及选择采集2种实时数据采集算法和乒乓缓存存储算法,可解决毫秒级仿真周期、海量数据的高速实时数据采集与存储。更多还原

【Abstract】 In order to make the functionality and performance test of all parts of the new planes accurate,and give assistance to the designers to maximize the test of each moment,the flight simulation platform proposes demand which needs higher simulation accuracy.It includes completing the real-time solver of flight simulation model,simultaneously collecting and storing 5 000 simulation data in 1 ms simulation cycle.This work introduces ping-pang cache storage algorithm and two kinds of real-time data acquisition algorithm which are compact acquisition and choose acquisition.And in this work,the millisecond level simulation cycles,huge amounts of high-speed real-time data acquisition and storage is solved.更多还原
