AI Technical Summary

Technical Problem

In the scenario where the EPA network and the DDS protocol are shared, the control system cannot have real-time communication at all network levels.

Method used

DDS data is generated based on the DDS topic at the node device, and the DDS data is converted into EPA data through the data conversion module of DDS and EPA, and finally the EPA data is sent to the EPA network through the EPA protocol stack module.

Benefits of technology

In the scenario where EPA network and DDS protocol are shared, the control system has real-time communication at all network levels, ensuring the reliability and real-timeness of data transmission.

Abstract

Embodiments of the present invention relate to a method, a computing device and a storage medium for distributed real-time communication. The method includes generating at least one DDS data corresponding to at least one DDS topic to be published via a DDS module of the node device at a node device based on at least one DDS topic to be published associated with the node device, wherein each of the at least one DDS data generated corresponds to a DDS topic, and the node device at least includes: a DDS module, a DDS and EPA data conversion module, and an EPA protocol stack module; converting the generated DDS data to generate EPA data via the DDS and EPA data conversion module; and sending the generated EPA data to the EPA network via the EPA bus connected to the node device based on the EPA protocol stack module. As a result, in a scenario where the EPA network and the DDS protocol are shared, the control system can have real-time communication at each network level.
