A DDS-based distributed C4I service system

Abstract

The invention provides a DDS-based distributed C4I service system comprising a data layer, a service layer and an application layer. The data layer is used for completing access and management of datain a system and providing data support for the service system; the service layer provides services required by the system; the service layer includes three layers which are a special support layer, apublic support layer and a computing service layer, which provide different surfaces and integrate data and services through data subscription and release and enterprise service; the application layer functions as a service registration center in the architecture of the whole service system, connects all the services, provides functions such as connectivity, technological differentiation, communication differentiation and technical services and manages and monitors interaction between all the services.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a communication and command system applying modern information and network technology. Background technique [0002] With the development of information technology and network technology, the information construction centered on the integrated electronic information system (Command, Control, Communication, Computer, Intelligence, Surveillance and Reconnaissance, referred to as C4ISR system) is the key to gaining information advantages. [0003] The C4ISR system is based on communication and relies on intelligence. Through the whole process of information acquisition, information transmission, information processing, decision-making command and information application, it organizes various scattered systems into an effective system. [0004] The C4ISR system is composed of sensors on different platforms, intelligence and reconnaissance systems, early warning and detection syst...

AI Technical Summary

Problems solved by technology

The characteristics of these system equipment are complex structure, heterogeneous equipment, distribution in different regions, harsh environment, frequent communication and interaction between systems, etc., which put forward high requirements for the real-time performance, interoperability, coordination and reliability of the C4ISR system. The requirements of the C4ISR system make the scale of the C4ISR system large, and the hardware and software components are complicated, making the design and development of the C41SR system a difficult task.”

Using traditional architecture technology to design and develop C4ISR architecture, there are some problems: it is difficult to effectively describe the overall capabilities of the system, the lack of C4ISR architecture meta-model in the modeling method, the object-oriented design method and development process are not provided, and there is no system Structural metrics and verification methods, etc.

Insufficiency of these key technologies leads to problems such as C4ISR system architecture design and non-issue cycle extension, cost increase, system quality is difficult to guarantee, etc.
