Message duplication eliminating method and device, electronic device, medium and unmanned vehicle

Abstract

The embodiment of the invention discloses a message duplication eliminating method and device, an electronic device, a medium and an unmanned vehicle. The method comprises the steps of: determining anode relation between publishing nodes by subscription nodes based on attribute information of the publishing nodes belonging to the same theme as the subscription nodes in a distributed system; according to the node relation, determining a communication mode between the publishing nodes; and according to the communication mode, performing registration of management modules corresponding to different communication mode to allow the management modules to receive business messages from the publishing nodes, according to the registration content and the unique identifier of the publishing nodes carried in the business message, determining that the business messages are sent to which subscription nodes, and assigning a certain communication mode to receive the business messages from which onepublish node in the registration content, sending the business messages to the corresponding subscription nodes so as to avoid that the subscription nodes receive the same repeated messages.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technologies, and in particular, to a method, device, electronic device, medium, and unmanned vehicle for message deduplication based on a distributed system. Background technique [0002] At present, unmanned vehicles mostly use topic-based publish and subscribe mode for communication. In order to improve the efficiency of data transmission, an adaptive communication method is generally adopted. For example, for communication within the same process, pointers can be passed directly; for cross-process communication with the host, shared memory can be used. [0003] Different communication methods are isolated, which results in that in some cases, the subscriber will repeatedly receive messages from the same publisher. For example, the same subscriber will use the pointer method within the process and read the shared memory method across the process. , the message of the same publish...
