摘　　要：为实时观测水下平台的工作状态,为水面工作人员提供操作依据,建立稳定实时的显控系统。结合TCP/IP通信,建立稳定的通信网络;并利用VC++和OpenGL建立三维实时仿真动画。针对程序时钟和数据传输时钟的不一致而产生的"数据真空"问题,设计一种算法——"中点逼近法"。经过多次船池实验,系统稳定地接收了水下平台的工作数据,很好地解决数据通信同步问题,并成功消除了"数据真空"现象。To observe the active status of a new underwater platform which works in deep sea,the web-based display-control system was researched to establish the stable TCP/IP correspondence network,and make the real-time 3D simulation with VC＋＋ and OpenGL.In order to solve the ＂data vacuum＂ phenomenon due to the inconsistency between the procedural clock and the data-transmission clock,the algorithm of ＂mid-point-approximation＂ was introduced to estimate the data at the procedural clock.The research indicated that the system is able to successfully solve data communication＇s synchronization and the ＂data vacuum＂ phenomenon.
