Embodiment 1

[0047] An embodiment of the present invention provides a wireless energy carrying communication system, such as figure 1 Shown, including transmitter subsystem and receiver subsystem.

[0048] Among them, the transmitter subsystem includes a signal generating module, a resonant circuit, a power amplifier circuit and a transmitting antenna.

[0049] The signal generation module is used to generate an energy-carrying signal according to the original signal and energy; the input end of the resonant circuit is connected to the output end of the signal generating module, and the resonant circuit is used to convert the electric field energy and magnetic field energy of the energy-carrying signal, thereby realizing the energy-carrying signal transmission; the input end of the power amplifier circuit is connected to the output end of the resonant circuit, and the power amplifier circuit is used to amplify the power of the energy-carrying signal; the input end of the transmitting anten...

Embodiment 2

[0067] An embodiment of the present invention provides a wireless energy-carrying communication method, such as Figure 5 As shown, including the following steps S1-S8:

[0068] S1. In the signal generation module, an energy-carrying signal is generated according to the original signal and energy, and the energy-carrying signal is spread spectrum and modulated.

[0069] Step S1 includes the following sub-steps S11-S15:

[0070] S11. The original signal and energy are framed by a signal generator to obtain an energy-carrying signal.

[0071] In the embodiment of the present invention, the original signal and the 8bit energy frame header are synchronized into a frame to obtain an 8bit synchronization frame header, and then the obtained synchronization frame header is combined with subsequent 4bit type frames (for distinguishing different signal types) and 20bit data frames (used to transmit data) together form a 32-bit energy-carrying signal frame, such as Figure 6 shown.

Abstract

The invention discloses a wireless energy-carrying communication system and method, which can transmit signals and energy at the same time, and can provide energy for the wireless equipment while performing information interaction with the wireless equipment. The present invention applies the spread spectrum communication technology to the wireless energy-carrying communication system. Before the energy-carrying signal is wirelessly transmitted, it is firstly subjected to spread-spectrum and modulation processing, and then demodulated and despread the signal in the receiver subsystem, which can It effectively reduces the bit error rate of the entire system, and at the same time, the energy-carrying signal processed by spread spectrum is less affected by various interference signals, so the spread spectrum modulation method can reduce the system's requirements for signal-to-noise ratio.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to the design of a wireless energy carrying communication system and method. Background technique [0002] Traditional power supply solutions (wired power supply, built-in battery, etc.) are currently the most important means of power supply, and their inherent defects in safety and convenience determine that they will increasingly fail to meet the needs of social development. At present, with the continuous popularization of smart wearable devices, all kinds of smart wearable devices such as smart bracelets, smart watches, and smart glasses can be seen everywhere. The capacity is not large and the charging power is not high; second, these devices are exposed to electromagnetic waves most of the time. Therefore, these devices can be charged anytime and anywhere with unlimited energy transfer. On the one hand, it saves users the trouble of taking of...
