[Example of ZEROSAI Implementation] Regional Development Bureau - River Embankment Protection Work - Managing water levels in three stages to prepare for sudden rises in water levels!
We will introduce a case study of the natural disaster prevention system ZEROSAI (NETIS registration number QS-150021-VE). It can be utilized not only for safety measures but also for creative ideas and technical proposals. Challenges on-site: Key focus points for evaluation [Operational Environment] - Install an [N Sensor] near the site to view wind speed predictions and observation data on the cloud. Since there is no power supply at the site, a solar power generation system will be installed. - Install a [battery-operated water level gauge] in the nearby river to monitor water levels. [Purpose of Implementation] - There is a dam upstream, and when sudden torrential rain occurs, the water level rises rapidly, necessitating quick evacuation. - Due to frequent crane operations, project management must ensure that work is conducted on days when wind speed predictions do not exceed the work stoppage threshold of 10 m/s. - Information sharing regarding work stoppages or changes in the schedule must be done swiftly. ■ Proposal (Example) For details, please download the PDF.
