Industry overview
The flood season in various regions of China is mainly between April and October, and the specific time varies according to the region and climate type. The flood season in the south is usually from April to September, while in the north it is from June to August.
During the flood season, heavy rain, flood and other natural disasters occur frequently, which will cause serious damage to agriculture, transportation, water conservancy and other aspects, so the early warning and response plan of the flood season is very important.
The flow velocity is an extremely important element in hydrological measurement. The purpose of observing the flow is to master its characteristics, study its change in time and distribution in space, and find out its activity law through analysis and research. River flow velocity measurement is an important work in river management, which helps to ensure river stability, embankment safety, prevent flood disasters, protect people's life and property safety, maintain water ecological environment, and realize sustainable utilization of water resources.
The deployment of UAV flood prevention early warning and emergency response system has many advantages, such as real-time monitoring, wide coverage and efficient rescue, reducing casualties, saving manpower and material resources, and improving the accuracy of early warning, which plays an important supporting role in flood prevention work.
Policy environment
The State issued the Catalogue of Advanced Technical Equipment for Flood Control and Rescue (2023 edition)
National Fire and Rescue Administration, Emergency Management departments (bureaux) of provinces, autonomous regions and municipalities directly under the Central Government, Emergency Management Bureau of Xinjiang Production and Construction Corps, relevant units and enterprises:
Guidelines for Building a Comprehensive Monitoring and Early Warning Platform for Urban Safety Risks
Promote the construction of all-factor standardization systems such as technology, management and capability, formulate the construction and operation standard systems of integrated platforms and sub-platforms, including basic standards, supporting technology standards, data collection management standards, construction management standards, information security standards, business application standards, etc., and standardize the data collection formats and platform construction and operation management processes. Enterprises, social organizations and scientific research institutions are encouraged to independently develop monitoring and early warning technologies, equipment, facilities and other standards.
System composition
Uav integrated management platform - flow measurement platform
The UAV flow measurement platform can conduct data analysis and processing in the cloud, real-time monitoring of water velocity, flow and other data, so as to facilitate relevant departments to timely understand water situation changes and make reasonable decisions. Through the cloud platform, multi-departments can also work together to improve the speed of emergency response and the efficiency of flood control command.
Current measurement mode
1- Single machine current measurement
The M350 UAV carrying MYUAV, 4-in-1 radar water level current meter, and H20N HD 5-in-1 hybrid camera arrive at the target site, and the wider river can quickly load the section information table, perform flow measurement for each section, and measure the water level elevation, surface water velocity and flow of each section at the same time after the task is completed.
2- Drone hangar flow measurement
The unattended airport UAV equipped with a single velocity current meter or video current meter is used to measure the flow, making up for the shortcomings of the fixed current meter that cannot move the flow meter. In the daily monitoring and management process of the reservoir, according to the planned route, it can not only monitor the flow rate of extra water within the scope of the reservoir at a fixed time, but also monitor the water flow rate in the required position at any time according to the demand. To help relevant departments to better grasp the changes in the water situation of the reservoir.
