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.
In addition to the conventional method of alerting on-site, a function to notify the bridge manager via 4G/LTE has been added.
