MinebeaMitsumi: Demonstration test with wireless power supply: Inspection of equipment in tunnel
-Utilizing microwave wireless power transmission technology-
MinebeaMitsumi and Kyoto University:
Inspect infrastructure structures using microwave wireless power transmission technology.
On October 9, it announced that it would start a social demonstration test of the monitoring system.
Inspect infrastructure structures:
With the cooperation of Kyoto Prefecture
Received a license for using radio waves
Monitor the fall and collapse of equipment,
Perform at the tunnel evacuation pit.
This experiment:
In this experiment, we will monitor the fall and collapse of heavy equipment.
“Smoke exhaust jet fans, etc., bolted to the tunnel” are to be monitored.

Kyoto University and MinebeaMitsumi Started Social Demonstration Test with Wireless Power Supply, Using the Joint National Strategy Special Zone
Summary
In the maintenance of social infrastructure that is aging and deteriorating,
there are various problems in terms of human resource shortages, economics, work efficiency, etc.,
there is increasing demand for inspection services that employ image processing technology, such as cameras and radars.
Kyoto University
has been conducting research into wireless power supply technology using electromagnetic waves (microwaves*1) for many years.
This time, with the cooperation of Kyoto Prefecture,
a social demonstration experiment will be conducted at the Jizo Tunnel evacuation tunnel*2 in Miyazu City, Kyoto Prefecture.
transmission system
In this experiment, to monitor the falling or collapse of heavy ancillary equipment such as jet fans for smoke exhaust that are bolted to tunnel structure frames,
we will use a recursive-type infrastructure monitoring system
that can collect sensing information in real time while transmitting power from a traveling vehicle to a sensor.
This system
is used in the Kyoto University COI program, developed mainly by the research and development group of MinebeaMitsumi Inc.
and is a combination of the elemental technologies of
microwave wireless power transmission,
high-speed image signal processing
battery-less bolt axial force sensors
that directly detects loose bolts.
In the demonstration experiment,
efforts toward social implementationwill be accelerated by confirming the usefulness and convenience of drive monitoring using microwave wireless power transmission technology and identifying practical issues.
