[Technical Proposal Example] Measures Against Heavy Rain in Erosion Control Dam Construction | Solutions for Sites with No Signal Reception

Utilizing Starlink to address mountainous sites where radio waves do not reach, optimizing water level management with precipitation forecasts 17 days in advance.

■On-site Issues The construction of sediment control dams takes place in steep mountainous areas, posing risks of sediment runoff and flooding during heavy rainfall. It is crucial to establish work decisions based on weather forecasts, real-time observations, and a rapid evacuation system. ■Proposal (Example) Introduce the natural disaster prevention system ZEROSAI, which combines ZEROSAI X-AI and Starlink. 1) Utilize 500m mesh precipitation forecasts up to 17 days in advance to make work decisions, changing the schedule when predictions exceed the threshold. 2) Automatically observe precipitation and water levels in real-time using weather observation devices and battery-operated water level gauges. In mountainous areas where radio signals do not reach, ensure cloud communication via SpaceX's satellite communication "Starlink," and conduct remote monitoring alongside on-site cameras. 3) When rainfall exceeds the threshold, immediately notify via business chat and alert devices to halt work. Water levels will be displayed in stages using a three-color indicator light. ■Points Possible with ZEROSAI - Enables planned project management with forecasts up to 17 days in advance - Responds to mountainous sites without radio signals through Starlink collaboration (equipment arrangements handled by Sysmet) - Visually communicates evacuation responses through three-stage displays on the three-color indicator light.
