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...

Problems solved by technology

However, when multiple devices are distributed in a network, there is still no relevant research on how to control the conversion between wireless energy and information transmission of each device based on time division.

And the traditional time-division-based distributed communication protocol CSMA protocol obviously cannot be directly used in the distributed networking of new equipment using wireless energy and information transmission technology.
