数据分发服务在指控系统中的应用设想

本文提出了将对象管理组织(OMG)的数据分发服务(DDS)技术应用于指控系统(Command and Control System)中实现系统在时间、空间、数据流上的松耦合达到降低系统耦合度和集成难度的目的. 同时结合对现有按照标准DDS规范编写的商用DDS软件不足的分析, 提出了在将DDS应用于指控系统中的基础上, 同时采用服务质量(QoS)控制, 带宽自适应性, 可扩展二进制变长编码, 多优先级队列, 以及信息可靠传输等技术方法进一步提高数据在指控系统中传输的高效性, 可靠性. 文章最后将DDS以及相关技术方法应用于指控系统后的综合效果与现有指控系统的各项技术指标进行了对比分析, 结果表明将DDS应用于指控系统中能够有效的解决现有指控中存在的诸多问题.

Application of Data Distribution Service in Command and Control System

In this study, the DDS (Data Distribution Service) technology of OMG (Object Management Organization) is applied to the command and control system to achieve the system''s loose coupling in time, space, data-flow so as to reduce the system''s coupling degree and the difficulty of integration. At the same time, based on the analysis of the shortages of the existing commercial DDS software that is compied according to the DDS standard, this study puts forward the application of DDS to the command and control system. Furthermore, it adopts QoS (Quality of Service) control, bandwidth adaptive, scalable binary variable length coding, multi-priority queues, technologies of reliable information transmission and other technical methods to further improve the efficiency and reliability of the data transmission in the command and control system. Then, the synthesized effect that DDS and related technical methods is applied to the command and the control system is compared with the technical indexes of the existing command and control system. The results show that the application of DDS to the command and control system can effectively solve these issues in the existing command and control system.
