Description

technical field [0001] The invention relates to a wireless energy-carrying communication system capable of accurately transmitting characters and images based on frequency shift keying and magnetic coupling resonance, which is characterized in that information and energy can be simultaneously transmitted through the same channel. Background technique [0002] With the rise of wireless technology applications, wireless information transmission and wireless energy transmission technologies continue to grow and develop, especially wireless information transmission, which is widely used in various fields in different technical forms such as WiFi, 3G / 4G networks, and microwaves. Research has also yielded laboratory-level gains. [0003] However, like other resources, the frequency resources known and used by humans are increasingly scarce. As an important national strategic resource, radio spectrum resources need to be used more efficiently and fully. Therefore, the concept of w...

Problems solved by technology

The transmission power of electromagnetic induction technology is large, but the coil heats up seriously during the transmission process, the transmission distance is short and the transmission efficiency decreases rapidly with the increase of distance, and it is easily affected by displacement and frequency changes; the transmission distance of microwave far-field radiation is long, but for the design of transmitting antenna High requirements, low transmission efficiency, susceptible to interference from climate and environmental factors, weak ability to penetrate obstacles

The transmission efficiency and transmission distance of magnetic coupling resonance are between the first two technologies, but the technology started relatively late, and the power and transmission distance still need to be improved
