Abstract

The invention discloses a data communication method and a data communication device. The method is applied to the data communication device, and comprises the steps of setting configuration database information for each node in N nodes of the data communication device, wherein N is an integer greater than or equal to 2; loading and analyzing the configuration database information, creating a group of data distribution service objects corresponding to each node based on the configuration database information, and acquiring N groups of data distribution service objects; configuring a data buffer for each node, and acquiring N data buffers; and performing data communication based on the N groups of data distribution service objects and the N data buffers.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data communication method and a data communication device. Background technique [0002] DDS-Data Distribution Service (DDS-Data Distribution Service) is a new generation of distributed real-time communication middleware technical specifications. It adopts a publish / subscribe architecture, takes data as the center, and provides rich Qos policies. It is formulated by the Object Management Group (OMG) and is used for Solve the problems of real-time data distribution, flexibility and Qos control in real-time distributed systems. Based on this technical specification, many data distribution service middlewares have been produced, which provide new means for communication between nodes in a distributed system. At present, data distribution service middleware has been widely used in ship control, digital TV system, flight simulator and military network system in developed countr...
