【摘要】 根据无人机系统的组成,分析了延时产生的原因、类型及对系统稳定性的影响。针对某地面控制仿真系统的系统架构特点,设计了该地面控制仿真系统的延时测试方案及软件。采用基于微软提供的高精度计数器接口函数及多线程编程技术有效正确地测量了地面控制仿真系统的遥控指令发送、遥测数据接收的延时时间,验证了系统设计的合理性。更多还原

【Abstract】 According to the compose of unmanned aerial vehicle system(UAVS),the causes,types and impacts on system stability of time delay are analyzed.Time delay testing scheme and software for the ground control simulation system(GCSS) are designed based on the characteristic of system architecture.Time delays on remote command sending and telemetry data reception are measured accurately and availably based on high precision counter interface functions and multithreading programming technology,and at the same time,reasonability of system designing is verified.更多还原
