Abstract: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.
