We have developed a method using mobile devices to identify plant equipments, especially for repair. After the accident of March 2011 at Fukushima, many nuclear plant operations have still been downed and it leads to the insufficiency of mature experience. The work assistance with IT is getting required under this situation. The IT device can provide appropriate information, e.g. operating instructions, to workers depending on the situation. In order to recognize the current location the arrangement informa...

Development of Identification Method of Equipments for Repair in Nuclear Plant

We have developed a method using mobile devices to recognize the current location in a plant where radio/marker such as GPS is not available. Depending on the site situation the device can provide appropriate information, e.g. operating instructions, to workers. In order to recognize the current location, we identify surrounding plant equipment and register its location as the current one. The mobile device with 3-D depth acquisition can extract a plurality of pipes, collate its feature amount with the DB, ...

Development of Location Detection Method in Plant Independent of Wireless Signal and Position Marker Identification

During the maintenance of nuclear power plants, it is important to reduce the radiation exposure of the workers. Auditory sensation has been widely used for alerting them to the radiation exposure such as personal dosimeters, which alert the user to radiation level by acoustic alarms. Although the measurement of radiation intensity has been more and more precisely, few study has focused on the selection of the effective alarm. The objective of this study therefore is to evaluate which acoustic feature is be...
