摘　　要：作为船体变形测量重要发展方向,惯性量匹配方法中多套惯性导航设备之间的时间同步性是影响测量精度的重要因素。为提高该方法在舰船以太网网络环境下的时间同步性能,首先,对时间敏感网络(TSN)进行了研究;然后,设计了惯性量匹配算法应用TSN的试验方案,搭建了试验样机;最后,通过试验样机验证了不同网络负载条件下,各网络节点之间的时间同步情况。试验结果表明:在舰船以太网环境下,应用TSN可使各网络节点具有较高的时间同步性,满足惯性量匹配方法的需求。Inertia matching method is an important development direction of hull deformation measurement.The synchroniza⁃tion between the attitude angular velocity of multiple inertial navigation equipment is an important factor affecting the measurement accuracy in inertial matching method.In order to improve the synchronization of this method in ship Ethernet network,firstly,time sensitive network is researched.Then,test scheme is designed and prototype is builded,which applied TSN.Finally,the synchroni⁃zation between network node is verified in different load.The test result shows that in ship Ethernet network,each network node has high synchronization applying TSN and inertial matching method's demand is satisfied.
