Ultrasonic Underwater Ranging Sensor: The Intelligent Eye of Unmanned Survey Vessels [Dayu Electronics]

　　Ultrasonic underwater ranging sensors use the principle of acoustic pulse reflection for high-precision measurement. The sensor transmits ultrasonic waves underwater. When the waves encounter the riverbed, silt, or other obstacles, they reflect back to the sensor. By calculating the time difference between transmission and reception, and combining this with the propagation speed of sound in water (with dynamic correction for water temperature and salinity effects), the target distance can be precisely calculated. For example, the echo sounder produced by Dayu Electronics uses 200kHz sonar technology and can measure water depths of up to 200 meters in relatively clean water.

　　1. Ultrasonic depth sensors mounted on unmanned survey vessels provide real-time underwater acoustic data.

　　2. Unmanned survey vessels can reach hazardous waters (e.g., rapids, shoals, polluted areas), avoiding risks associated with manual wading. Equipped with multiple depth sensors and combined with high-precision RTK positioning, they can measure water depths at different locations in real time and transmit the collected data wirelessly to a backend system via RTU.

　　With the integration of 5G, AI, and digital twin technologies, ultrasonic ranging sensors will play a greater role in smart waterways, ecological monitoring, and emergency flood control. The collaborative operation of "sensors + drones + unmanned vessels" enables the construction of digital twin river basins, allowing for early simulation of flood evolution and optimized flood control decision-making.
