Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the all-optical space information network structure that can be dynamically connected, taking four nodes as an example, when the first node 1 communicates with the second node 2 in the communication link, the first node 1 uses its own target scanning and The tracking device finds the second node 2, and the first node 1 transmits the information to the information receiving device of the second node 2 through its own communication information transmitting device. In order to improve the speed and reliability of information transmission, the first node 1 finds the third node 3 through its own target scanning and tracking device within the range of scanning angle θ, and transmits the communication information to the third node 3. Node 3 then transmits the information to the information receiving device of the second node 2 thro...

Abstract

An all-optical spatial information network allowing dynamic linking and information transmitting devices of the all-optical spatial information network are applied to the field of space communication. To solve technical problems of an existing spatial information network, the all-optical spatial information network is structurally composed of a plurality of nodes, each node is provided with an information transmitting device, an information receiving device and a target scanning and tracking device, and the scanning angle of each node is theta; according to the nodes, when the first node is in communication with the second node, the first node finds the second nodes through the corresponding target scanning and tracking device and then transmits information to the information receiving device of the second node through the corresponding information transmitting device; meanwhile, the first node finds the third node within the scanning angle theta through the target scanning and tracking device and then transmits communication information to the third node, and the third node transmits the information to the information receiving device of the second node through the corresponding information transmitting device; the first node, the second node, the third node, the four node and the like form the all-optical information communication network.

Description

technical field [0001] The invention relates to a dynamically connected all-optical space information network and an information transmitting device thereof, which are mainly used in the fields of ultra-long-distance space communication such as deep space and interstellar space. Background technique [0002] The space information network uses space platforms such as satellites, balloons, and drones as carriers to acquire, transmit, and process space information in real time. It can serve major applications in ocean navigation, emergency rescue, navigation and positioning, air transportation, and aerospace measurement and control. It supports high-dynamic, broadband real-time transmission for earth observation, and supports ultra-long-distance, long-delay transmission for deep space exploration. Therefore, the security and reliability of the connection between space information networks is a difficult problem for space information networks. In space information network commun...
