The flash flood warning system consists of a simple water station, a simple rainfall station, a wireless early warning broadcast and a household alarm (APP message can also be selected) through wireless connection.
| Alert Level | Trigger Threshold | Response Protocol |
|---|---|---|
| Yellow | 80% of danger level | Automated broadcast alerts + Platform notifications |
| Orange | 90% of danger level | SMS to residents + Emergency team mobilization |
| Red | Critical threshold | Full-channel activation (broadcast/SMS/in-house/authority hotline) |
System stability and security: The early warning system uses a variety of communication methods, can still work normally under the condition of network interruption and power failure, to ensure that the flood disaster monitoring is not interrupted, and to protect the safety of people's lives and property;
Automatic data collection: collect rainfall information in real time, and send the real-time rain situation to the mountain flood business platform, so that the flood control staff can obtain information in time, and provide support for the mountain flood early warning decision;
Diversification of early warning means: manual early warning, platform early warning, short message early warning, broadcast early warning, a full range of early warning means to convey early warning information to everyone;
Multi-communication links: Monitoring and warning equipment support 3G/4G/5G full Netcom /NB-IOT/ Beidou and other public network communication and local LoRa-Mesh AD hoc communication, to achieve mutual backup monitoring and warning transmission network;
Accurate early warning and early warning into households: collect rainwater information in real time, and send rainwater information to residents' homes, so as to realize the early warning information directly into households and people, and increase the transfer time of the masses;
Low power application scenarios: The system monitoring equipment adopts low power design, and can use solar energy combined with battery power supply, which is not limited by remote mountainous areas and other environments.
