| 摘 要： | 在多武器平台、大战场环境的视景仿真中,仿真实体与仿真节点的过多使不必要网络数据量大大提高.为了减少不必要网络数据量,该文从实用性的角度介绍了两种应用技术,一是应用HLA中数据分发管理服务（DDM）来限定传输数据的范围,按照数据值域来对数据的接收和发送进行过滤,有效降低了冗余数据的传输,该文提供了接收方的实现方法与主要代码;二是采用DR递推算法控制节点的数据发送,有效降低了数据帧的发送频率并使视景中仿真实体运动平滑无跳动,该文介绍了DR算法与DR模型并提供了实现一种算法的代码.

| Abstract: | When developing a visual simulation system of great battlefield environment and multi-weapon system,the numerous simulation nodes and simulation entities would make the data in network increased greatly.To dcrease the unnecessary data in network,this paper presents two practical technologies based on practicability.One is applying DDM(Data Distribution Management) technology(a service of HLA)to reduce the unnecessary data effectively.This technology is used to restrict the range of data transmitted and according to the data region to filtrate the data that would be sent or subscribed.The other is applying DR(Dead Reckoning) arithmetic to control the data to be sent.This technology decreases greatly the transmitting frequency of data frames and moreover can make the simulation-entity's motion smoothly.The paper presentes the DR arithmetics,DR models and program code of one DR arithmetics. |
