摘要
Abstract
The simulation system running under realtime is always required to ensure the credence of experiment as well as the safety of three axis turntable or the high precision inertial navigation devices.A timing method using external hardware clock based on Windows + RTX realtime system platform is used to make the system with high timing accuracy when running periodic timing target.Test results show that the timing method of using external hardware clock provides better accuracy and higher stability than using software clock.The hardware clock may have great engineering application value especially for distributed realtime simulation system.关键词
