[0103] Example

[0104] Such as image 3 As shown, there are three distributed nodes in the network: node 1, node 2, and node 3. Initially, all three nodes are in the energy harvesting state. When node 1 wants to send data to node 2 and obtains the channel to enter the transmission state, it periodically sends the notification frame of node 2. Node 2 cannot receive the notification frame in the energy harvesting state, and node 3 is also in the energy harvesting state at this time. When node 2 enters the energy harvesting state for more than T2, it enters the receiving state. At this time, it receives the periodic notification frame from node 1, and then switches to the transmission state to send a notification reply frame to node 1. At this time, although node 3 has also entered the receiving state after the timeout of the energy harvesting state, since it is not the target notification frame sent to itself, it enters the energy harvesting state after the receiving state has t...

Abstract

The invention provides an energy transmission supported wireless communication device and method and relates to the field of wireless energy transmission. The energy transmission supported wireless communication method includes that an antenna is connected with a radio frequency energy collection module, the microwave radiation energy is collected and stored, and nodes are located in the energy collection state; or the antenna is connected with an information demodulation module, demodulation is performed on received radio frequency signals to obtain demodulation data, and the nodes are located in the receiving state; or the antenna is connected with a transmission module, modulation is performed on transmission data to obtain radio frequency signals to be transmitted, and the nodes are located in the transmission state. According to the energy transmission supported wireless communication device and method which is applicable to an energy limited network such as a wireless sensor network, the multiple functions of energy collection, information transmission, energy transmission and the like can be provided and accordingly the energy efficiency of the network can be improved and the battery life of a network terminal can be extended.

Description

technical field [0001] The present invention relates to the field of wireless energy transmission, in particular to a wireless communication device and method supporting energy transmission. Background technique [0002] As a means of energy transmission, wireless energy transmission can realize power transmission in a non-contact state without using cables and other media. In recent years, wireless energy transmission has been successfully applied in fields such as wireless charging, and some explorations have been made in the combined field of simultaneous transmission of wireless energy and information. At present, wireless energy and information are simultaneously transmitted, and there are two methods of magnetic field resonance and microwave radiation transmission, which correspond to narrowband and broadband communication systems respectively. [0003] The magnetic field resonance technology was first proposed by the Massachusetts Institute of Technology in the Unite...
