Embodiment Construction

[0045] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] Such as figure 1 As shown, the multi-device power and information synchronous wireless transmission system includes a master node and multiple slave nodes, using the principle of magnetic coupling resonance wireless transmission technology, and the master node and slave nodes are installed on the equipment mounting board in the form of a track. The multi-resonance wireless transceiver coils of the master node and the slave node have two resonance frequency points, of which the low frequency point is mainly used for the master node to supply power to each slave node, and the high frequency point is used for information exchange between the master node and each slave node.

[0047] The system assigns bus communication addresses to each node, and each node has a unique address, and the communication protocol between each node complies with GJBZ209-...

Abstract

A system and method for synchronizing wireless transmission of power and information between multiple devices. The power and information synchronous wireless transmission system between multiple devices includes a master node and multiple slave nodes, and adopts the principle of magnetic coupling resonance wireless transmission technology. The multi-resonant wireless transceiver coils of the master node and the slave node have two resonance frequency points. The low frequency point is mainly used by the master node to supply power to each slave node, and the high frequency point is used for information exchange between the master node and each slave node.

Description

technical field [0001] The invention relates to a system and method for synchronous wireless transmission of electric energy and information between multiple devices. Background technique [0002] The electrical and electronic systems of aerospace vehicles, vehicles, ships and other equipment are complex electric energy and information interaction networks. Traditional system designs use cables to transmit information and electric energy, thus forming a complex cable network with complex connections. Design, production and installation The process is labor-intensive and prone to failure, and these cables also take up a lot of weight and space, seriously affecting equipment performance. [0003] At present, preliminary research has been carried out on wireless energy and information synchronous transmission technology at home and abroad, and basic point-to-point transmission has been realized, mainly through the following technical means: adding signal coils to realize parall...
