Space multi-node laser ad hoc network communication system

Abstract

The invention discloses a space multi-node laser self-organized network communication system, and belongs to the technical field of the wireless laser communication and network. The problem existing in the traditional space laser communication networking system is solved. The system is composed of six nodes, each of the first node and the sixth node is composed of an optical transmitting / receivingmodule, a gigabit network switch, a group of large-field laser transmitting lens group and a group of optical receiving lens group; each of other nodes is composed of two optical transmitting / receiving modules, one gigabit network switch, two groups of large-field laser transmitting lens group and two groups of optical receiving lens group; the gigabit network switch in each node is connected with the optical transmitting / receiving modules; and the optical transmitting / receiving modules are respectively connected with the large-field laser transmitting lens group and the optical receiving lens group; various nodes are mutually connected through the corresponding large-field laser transmitting lens groups and the optical receiving lens groups; the data transmission among any nodes in the self-organized network system is realized; the space multi-node laser self-organized network communication can be realized, and the system is suitable for the data chain transmission in the future intelligent internet of things.

Description

technical field [0001] The invention relates to a space multi-node networking communication system, in particular to a large field of view free space laser ad hoc network communication system, which belongs to the technical field of wireless laser communication and network. Background technique [0002] Space node self-organizing network communication technology will become one of the core technologies of the future smart Internet of Things. The use of a large number of radio frequency electronic components and equipment in the smart Internet of Things will create a complex electromagnetic environment, and the spectrum resources available for network communication will also be very tight. A data transmission anti-interference broadband ad hoc network technology is urgently needed to build the smart Internet of Things. The optical communication medium is anti-electromagnetic interference, wide bandwidth, and does not occupy spectrum resources. It is one of the best means for ...
