[ZEROSAI Introduction Case] River Disaster Recovery Work - Stage Water Level Alarm

In conjunction with weather forecasts, manage water levels in three stages to prepare for rapid increases due to heavy rainfall!

We will introduce case studies of the disaster prevention system ZEROSAI (Zero Sai) (NETIS registration number QS-150021-VE) in civil engineering and construction work. By centrally managing weather information, 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] - A battery-operated water level gauge is installed near the river to monitor water levels. If the observed values exceed the standard level, a three-color indicator light is used to implement responses according to the level of danger. - An N sensor is installed nearby to view wind speed and rainfall predictions and observational data on the cloud. Since there is no power supply on site, a solar power generation system is installed. [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 only 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 conducted swiftly.
