Problems solved by technology

[0002] At present, the electricity used for exhibition in the exhibition hall is drawn from the ground plug or wall plug. Due to the limited number of ground plugs, the flexibility of exhibition layout is very poor, which is not conducive to power consumption terminals (mobile showcases, TVs, touch-screen all-in-one machines, interactive electronic devices) ) placement, the current solution is to use temporary trunking to connect open wires, the disadvantages are unsightly and poor safety, and it is not suitable for public places such as exhibition halls

Abstract

The invention discloses a movable wireless power supply system for an exhibition hall. The system comprises a wireless power supply facility buried at the underground of the exhibition hall and receiving devices equipped on each piece of electric equipment. The wireless power supply facility comprises a plurality of emitting devices, and each of the emitting devices is electrically connected to a power distribution cabinet through a power line. Each of the emitting devices comprises a rectifier circuit, a power factor correction circuit, an inverter, an impedance transformation circuit, and a transmitter coil which are electrically connected orderly. An emitting control circuit and an emitting end wireless communication circuit are in a bidirectional connection. Each of the receiving devices comprises a receiving end coil, a load compensation circuit, a high frequency rectifier and filter circuit, a DC-DC circuit, and a receiving end wireless communication circuit which are electrically connected orderly. The receiving end wireless communication circuit and the receiving control circuit are in a bidirectional connection. According to the movable wireless power supply system, the wireless power supply in a range of 10 cm to 30 cm between the ground and the electric equipment is realized.

Description

technical field [0001] The invention mainly relates to the technical field of wireless power supply, in particular to a special movable wireless power supply system for exhibition halls. Background technique [0002] At present, the electricity used for exhibition in the exhibition hall is drawn from the ground plug or wall plug. Due to the limited number of ground plugs, the flexibility of exhibition layout is very poor, which is not conducive to power consumption terminals (mobile showcases, TVs, touch-screen all-in-one machines, interactive electronic devices) ) placement, the current solution is to use temporary trunking to connect open wires, the disadvantages are unsightly and poor safety, and it is not suitable for public places such as exhibition halls. Contents of the invention [0003] The purpose of the present invention is to make up for the defects of the existing technology and provide a special movable wireless power supply system for exhibition halls.
