On the bridge triage implemented by Toyama City, they decide to repair and renewal the important bridges preferentially with a limited budget.
If other bridges cannot be repaired or renewed for the time being, it is necessary to monitor the conditions.
Because it is difficult to patrol and monitor a lot of bridges with limited staff and budget, a girder end anomaly detection monitoring system was installed on actual bridges.
The equipment was installed at the site, and a system was built to alert the user by LED lights when anomalies such as opening or steps occur at the end of the bridge girder.
