Description

technical field [0001] The invention relates to the technical field of radio and automation engineering, in particular to a tracking type wireless charging device and method. Background technique [0002] With the development of science and technology, human beings have set foot on a wider range of exploration of the world. Deep water operations and space operations are becoming more and more common. Under these extreme working conditions, on the one hand, due to volume and weight limitations, it is impossible to carry large capacity On the other hand, wired charging cannot satisfy the spatial arbitrariness of device posture, and poses challenges to sealing and safety. Combined with the above application background, it is particularly important to realize WPT (Wireless Power Transmission, wireless energy transmission) of electric equipment, and the charger is required to track and charge electric equipment, so as to solve the problem of flexible wireless transmission of elec...

Problems solved by technology

[0004] For the transmission of microwave energy, people put forward the ubiquitous UPS (Uninterruptible Power System, uninterruptible power supply) concept, that is, to use the radiation source in the closed space to realize the space microwave energy distribution of "everywhere, everywhere". This method not only wastes a lot of energy, but also the human body is exposed to excessive microwave energy environment for a long time, which has serious safety hazards such as carcinogenic, teratogenic and mutagenic

For the radio frequency signal transmission in the near-field area, the current relatively mature technology is phased array based on beamforming, and the transmission orientation is realized by changing the amplitude and phase of the phased array antenna, which has been applied to high-precision military industries such as radar field, but the system design and manufacture of this method are very complicated, and key system components such as magnetrons and phase shifters are expensive, and are not suitable for marketization and civilian operations

In addition, the beamforming-based phased array transmission system is difficult to realize tracking wireless charging for electrical equipment with flexible location changes, resulting in low transmission efficiency
