We deployed a comprehensive solution integrating intelligent navigation and coastal safety emergency functions. The core equipment includes: 1) High-durability intelligent guide signs: made of 316 stainless steel and IP68 protected, providing real-time information on tides, weather, and activities; 2) Coastline SOS warning posts: deployed along dangerous waterways, equipped with a one-button emergency alarm, a loud siren, and a flashing light. When a tourist is in danger, pressing the button immediately locks their location and simultaneously notifies the monitoring center and nearby lifeguards, achieving seamless rescue through "one-button call, precise positioning, and rapid response."
