Abstract

The invention provides a distributed real-time communication method and device for air-ground unmanned system, and a multi-unmanned system, and relates to the technical field of multi-unmanned systemcommunication. The method comprises the steps: obtaining initialization information of a plurality of unmanned platforms in an air-ground unmanned system; grouping the plurality of unmanned platformsaccording to the initialization information, determining a group leader and group members of each group, and disconnecting communication connection with all the group members, the group leader establishing communication connection with each group member in the group; issuing a first-level survey to each group leader, issuing a second-level survey to each group member in the group by each group leader based on the first-level survey, and providing feedback of a first-level response based on the second-level response in response to a second-level response made by each group member in the group for the second-level survey; and conducting processing based on the first-level response from each group leader, and sending a control instruction. According to the invention, a double-layer star network communication architecture is constructed through grouping, and the load of a server is effectively reduced through investigation and response communication modes, so that the stability of the system is improved.

Description

technical field

[0001] The invention relates to the technical field of multi-unmanned system communication, in particular, to a distributed real-time communication method and device for an air-ground unmanned system and a multi-unmanned system. Background technique

[0002] With the development of various technologies of the unmanned control system, the air-ground cooperative unmanned system has a wide range of application prospects, so it has received more and more attention. The air-ground unmanned system integrates the characteristics of UAV's wide field of vision, rapid deployment, strong exploration ability and concealed work. It is widely used in the fields of map construction, regional search, modern operations, and anti-terrorism.

[0003] In a large-scale distributed air-to-ground unmanned system cluster, due to the large number of communication nodes in the system, and the distributed and heterogeneous characteristics, there are dynamic changes, data delays and loa...
