[0002] In the operation and management of remote, elongated hydropower station reservoirs, accurate data on water volume and level is crucial for power generation scheduling, flood warning, and comprehensive water resource utilization. Traditional water volume data collection methods have several limitations: firstly, due to the unique terrain of elongated reservoirs, their large span and remote locations often make it difficult to lay stable wired communication networks, leading to data transmission difficulties; secondly, many reservoirs are located in remote mountainous areas with poor or no 4G and 5G signal coverage, rendering conventional mobile network-dependent data collection equipment unusable. Furthermore, manual on-site measurements are not only costly in terms of manpower and resources but also inefficient, failing to reflect real-time changes in reservoir water volume and thus unable to meet the demands of modern, refined hydropower station management. Therefore, this invention provides a remote reservoir water volume collection device based on UAV relay to collect water volume data from reservoirs in remote areas. Summary of the Invention
