Problems solved by technology

[0003] For long-distance wireless power transmission technology, there are currently two commonly used communication technologies: one is in-band communication. The impact of power transmission will also become greater and greater, which will have a greater impact on the signal quality of the power supply. In addition, the communication speed is relatively slow, which cannot meet the requirements in many occasions; the other is Bluetooth or 2.4G communication mode, the communication speed is relatively fast, but Due to the wide variety of Bluetooth transmission protocols and other 2.4G devices, and they all share signals in this frequency band, it will inevitably lead to mutual interference between signals in this frequency band; secondly, the Bluetooth wireless communication protocol is not a free technology, any manufacturer using Bluetooth technology must pay a patent fee to Bluetooth-related organizations, and this part of the fee is usually reflected in the cost of the product, resulting in an increase in cost
[0004] The existing wireless power transmission system includes a power receiving device coil module that receives power and a charging coil module that transmits power; when charging, if the positions of the power receiving coil module and the charging coil module are different, the power transmission efficiency will be reduced, resulting in greater loss , and the above two commonly used communication technologies can only provide relevant communication, but cannot achieve distance detection and angle detection, so additional devices and equipment need to be added to realize this function

Abstract

The invention discloses a wireless power transmission system. The wireless electric energy transmission system comprises a wireless electric energy transmitting device and a wireless electric energy receiving device. The wireless electric energy transmitting device comprises a transmitting device micro-control unit, a transmitting device power module controlled by the transmitting device micro-control unit, and a transmitting device visible light communication and data acquisition module. According to the wireless electric energy transmission system, visible light is adopted for real-time communication, distance detection and angle detection between the wireless electric energy transmitting device and the wireless electric energy receiving device, electromagnetic interference cannot be generated due to the characteristics of the visible light, other devices cannot be affected by electromagnetic waves, and related crosstalk does not exist between the devices; therefore, the extremely high communication rate is achieved, and the highest communication rate can reach more than 10 Gpbs.
