WIRELESS POWER SUPPLY SYSTEM AND HUMAN BODY IRRADIATION POWER AMOUNT ESTIMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a wireless power supply system and a human body irradiation power amount estimation program which can reduce an estimation error of a human body irradiation power amount.;SOLUTION: A wireless power supply system comprises: a power supply device 100 which outputs power supply radio waves; a plurality of wireless sensors 200 which receives power supply; and at least one human body tag 300 which is held by a human body existing in environment. The power supply device 100 performs communication with the human body tag 300 per slot to estimate a human body irradiation power amount per slot to the human body holding the human body tag 300 (S8), further calculates the human body irradiation power amount per cycle as an average of the human body irradiation power amount for all slots (S11), and when the human body irradiation power amount per cycle exceeds a predetermined specified value (NO in S12), restricts power supply to a slave unit (S14).;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2021,JPO&INPIT
