Wireless power transfer communication system

Abstract

The present invention provides a wireless power supply and communication system that can efficiently wirelessly supply power to electrical devices and enable wireless communication between electrical devices and communication equipment using the wirelessly supplied power. [Solution] The wireless power supply communication system 1 comprises a leaky coaxial cable 2, a plurality of sensor devices 3 arranged within the range of radio waves from the leaky coaxial cable 2, a high-frequency power supply device 5 that outputs high-frequency power for supplying power to the plurality of sensor devices 3, a communication device 6 that communicates wirelessly between the plurality of sensor devices 3, and a common device 4 arranged between the high-frequency power supply device 5 and the communication device 6 and the leaky coaxial cable 2. The high-frequency power output from the high-frequency power supply device 5 is input to the leaky coaxial cable 2 via the common device 4, and power is supplied to the plurality of sensor devices 3 by radio waves leaking from the leaky coaxial cable 2. In addition, signals transmitted wirelessly from each sensor device 3 are transmitted to the communication device 6 via the leaky coaxial cable 2 and the common device 4.
