my country's first rainfall station "Yushen-1" that can be deployed by drones has been officially launched recently. The equipment was jointly developed by the Chengdu High-tech Disaster Reduction Research Institute, the Electric Power Science Research Institute of the Sichuan Electric Power Company of the State Grid Corporation of China, the State Grid Sichuan Ya'an Electric Power (Group) Co., Ltd., and other units.
The birth of "Yushen-1" aims to solve key problems: many flash floods and debris flow disaster areas are located in uninhabited areas with extremely poor transportation, communication and maintenance conditions, making rainfall monitoring difficult.
Taking Sichuan as an example, the density of rainfall stations in the western alpine areas is much lower than that in the central and eastern areas. Utilizing widely used load-carrying drones, "Yushen-1" can be easily deployed to uninhabited areas, significantly reducing the difficulty of station establishment and effectively filling the monitoring gap.
Its deployment process is highly intelligent: after the drone delivers the equipment to a 10-meter-wide tree-free area, the "Rain God-1" can autonomously adjust its posture to ensure that the rain gauge is level, and then starts working. Even in areas without ground signals, real-time data can be transmitted back to the early warning center through Beidou satellites.
At present, the monitoring data of "Yushen-1" has been connected to the Sichuan Provincial Department of Water Resources and the Department of Emergency Management.And integrated into the provincial natural disaster dynamic risk monitoring and early warning platform, it will significantly improve the monitoring, early warning and service capabilities for flash floods, debris flows, landslides and other disasters.
After the large-scale application of "Yushen-1", combined with the new generation rainfall estimation and forecasting technology platform (integrating satellite, radar and rainfall station data) in the "Jiebang Take Command" project, it will effectively improve the disaster monitoring and progressive early warning capabilities of flash floods, debris flows, and landslides, and provide stronger protection for the safety of personnel and the safety of key facilities (including power grids).
