Wireless image and electric power transmission device and wireless image and electric power transmission method

Abstract

The invention discloses a wireless image and electric power transmission device, which comprises a first receiving / transmitting unit and a second receiving / transmitting unit. The first receiving / transmitting unit and the second receiving / transmitting unit comprise an induction coil, a modulating unit, a current changing unit, a coding / decoding unit, a storage unit and a microprocessor respectively, wherein the induction coil is used for receiving / transmitting a carrier signal; the modulating unit is used for modulating and recovering the carrier signal; the current changing unit is used for performing alternating-direct current conversion on a current; the coding / decoding unit is used for coding / decoding image data and user command information; the storage unit is used for storing the image data and providing system operating space for the first and second receiving / transmitting units; and the microprocessor is used for controlling the induction coil, the modulating unit, the current changing unit, the coding / decoding unit and the storage unit according to a user command and performing wireless image and electric power transmission. The invention also relates to a wireless image and electric power transmission method.

Description

technical field [0001] The present invention relates to a wireless image and power transmission device and method, in particular to a wireless image and power transmission device and method applied between portable electronic products and display devices. Background technique [0002] Existing electronic products all aim at pursuing miniaturization and portability. However, the more miniaturized the portable electronic product, the volume of the battery is bound to be limited, and the capacity of the battery is also smaller, so the power supply duration of the electronic product is shorter. In addition, existing electronic products tend to be more multi-functional for entertainment. For example, electronic products can be used to shoot videos and images, and videos or images can also be stored in these electronic products, and these videos or images can be directly watched on the screens of electronic products. However, due to the miniaturization of electronic products, the...

Problems solved by technology

However, the smaller the portable electronic product is, the volume of the battery is bound to be limited, and the capacity of the battery is also smaller, so the power supply duration of the electronic product is shorter

In addition, existing electronic products tend to be more multi-functional for entertainment. For example, electronic products can be used to shoot videos and images, and videos or images can also be stored in these electronic products, and these videos or images can be directly watched on the screens of electronic products. However, due to the miniaturization of electronic products, the screen size is bound to be limited, so the display and viewing effects of video or images are not satisfactory

If you want to watch videos or images on a larger screen, the existing method is to connect electronic products and display devices with data cables, and the image data is transmitted through data cables, but using data cables to connect electronic products and display devices, electronic products must be placed Near the display device, its use is restricted

In addition, existing electronic products generally use cables to transmit electric energy for charging. Frequent plugging and unplugging of data cables and cables between electronic products and display devices will undoubtedly affect the service life of electronic products and display devices, and at the same time make electronic products limited use
