Data distribution service (DDS) communication system

Abstract

The invention discloses a data distribution service (DDS) communication system. The system uses a publishing / subscribing communication mode and comprises a plurality of publishers, a plurality of subscribers, a plurality of middle pieces, a register data type module, a generation topic module, a publishing data module, a seeking topic module, a subscribing topic module and a receiving data module; one publisher firstly calls the register data type module, returns the module after succeeding in calling the module, and then calls the generation topic module to generate a topic on the middle pieces; one subscriber discovers the topic on a network by seeking the topic module, and then calls the subscribing topic module to subscribe the topic; and the publisher calls the publishing data module to send data to the middle pieces when receiving words of subscribing the topic, and the subscriber receives the data on the middle pieces through the receiving data module. The DDS communication system is high in real time performance and very applicable to various radar weapon systems which are high in requirement of real time performances and large in handling capacity.

Description

technical field [0001] The invention relates to a communication system, in particular to a DDS communication system applied in a radar weapon system. [0002] Background technique [0003] In the existing radar weapon system, the communication system mostly adopts the model of carrying on the information communication through the Ethernet through the Socket protocol stack. First create a Socket; then bind the IP address and specify the port number for sending and receiving; then set the socket according to the propagation mode; finally realize the sending and receiving of messages through the read and write operations on the specified address port. The disadvantage of this method is that the integration flexibility and scalability are poor, it is necessary to formulate an information interface protocol between communication devices, the separation of software and hardware cannot be realized, and the dynamic configuration and reorganization of system control functions are di...

[0004] The communication integration flexibility and scalability of the radar weapon system are poor. It is necessary to formulate an information interface protocol between communication devices, and the separation of software and hardware cannot be realized, which makes the dynamic configuration and reorganization of system control functions difficult.
