Embodiment Construction

[0031] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0032] Such as figure 1 As shown, a network communication architecture applied to a multi-node networking information transmission system, including: a master control node, a relay forwarding node, and an execution node;

[0033] The master control node is used to control the selection of the working mode of the master control node, the relay forwarding node and the execution node, and the working modes include a one-way uplink communication mode, a one-way downlink communication mode, and a two-way uplink and downlink communication mode; Among them, the one-way uplink communication mode means that the master control node sends instruction data to each execution node through the relay forwarding node; the one-way downlink communication mode means that each execution node forwards the status data and detection data through the relay The node sen...

Abstract

The invention relates to a network communication architecture applied to a networking information transmission system and a communication method. The network communication architecture is composed of multiple nodes, such as a master control node, a relay transmitting node and a plurality of task executing nodes. The network communication architecture can reasonably restrain the space distribution of the nodes according to the different functions of the nodes. A combined communication mode of various communication systems of CDMA (code division multiple access), FDMA (frequency division multiple access) and TDMA (time division multiple access) is adopted, the relay transmitting node is utilized to realize the BVR (Beyond Visual Range) bidirectional information transmitting capacity of the master control node and the task executing nodes, and the problem of multi-node cooperative work of the networking information transmission system is solved.

Description

technical field [0001] The invention relates to a network communication framework applied to a multi-node networking information transmission system, and belongs to the technical field of wireless networking communication. Background technique [0002] Multi-node networking information transmission systems are widely used in military and civilian applications. It has become a typical application mode of information transmission systems to complete tasks that cannot or are difficult to be completed by a single node through wireless networking and mutual cooperation of multiple nodes. The network communication architecture is the basis of the multi-node networking information transmission system, and the optimized network communication architecture will have an important impact on the performance of the entire information transmission system. Especially in tasks such as ground observation by a ground command vehicle and a network of multiple UAVs, the design of the network com...
