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.
