Acoustic-Optical-Electronic Monitoring and Alarm Station for Flash Floods

The On-Site Acoustic-Optical Monitoring and Alarm Station integrates traditional monitoring stations with acoustic-optical alarm functions. It provides real-time monitoring of rainfall and water levels in small watersheds, triggering automatic alarms (voice, flashing lights, etc.) when thresholds are exceeded. The system supports multi-channel data transmission (Ethernet, 4G, BeiDou, LoRaMesh) and features intelligent voice response, enabling precise early warnings via cloud-based alerts.
