An on-site inspection support system using radio frequency identification tags and personal digital assistants
Abstract: Inspectors of buildings including power plants have to carry a bulk of documents
and drawings to perform their tasks, otherwise they have to memorize extensive
knowledge and data about the structures and facilities. Thus, a light and handy IT
solution system for supporting inspectors is desired. In this research, we propose
and develop a prototype on-site inspection support system. This system consists of
a RFID tag system, a PDA connected to the Internet, a voice input/output system,
and a digital camera.
In our approach, senior inspectors' knowledge such as advices and warnings
regarding each facility and structural member for inspection is input to RFID tags
via voice at the site as if the inspector is teaching a junior inspector. And each
RFID tag is glued to the facility or member. A junior inspector can obtain such
valuable knowledge later on when he or she inspects the building alone from the
reader-writer and PDA system. This system will enable senior inspectors to
transfer their expertise that can be excited only at the site to a knowledge system.
The information in the RFID tags can be altered or augmented when necessary.
RFID tags can carry not only inspectors' advices and warnings but also the ID,
main feature and recent inspection data of each facility or member. The inspector
can have access to the corresponding drawings, specifications, data of testing, etc.
from the ID of the RFID tag by the PDA. When more information is needed, the
inspector can get information by the PDA from the headquarters databases via the
The sound input system can be used to record sounds of various machines such as
generators, compressors, sirens, etc. and the recorded sounds can be analyzed and
evaluated on site by this system. Digital photographs can also be taken and stored
in the database and compared with the previous ones for inspection purposes.
