Tethered drone Another function of this tether is data fiber optic cable. When natural disasters occur, communication physical facilities such as base stations are often damaged. The complete restoration takes time. The payload of a tethered drone is generally 5kg-15kg, and the flying height can reach 200 meters. Therefore, a micro base station can be placed, and Signals are transmitted through optical fibers. As long as the plane rises to 50 meters, it can grasp the situation within a few kilometers.
Generate multi-spectral images with the help of a multi-spectral imager equipped on the system to intuitively and comprehensively monitor the surface water environment quality status, and provide thematic maps of environmentally-friendly drone water eutrophication, water bloom, water transparency, and pollution status of suspended solids outlet In order to achieve the purpose of monitoring the water quality characteristics of environmental protection drones. The drone can also be equipped with a mobile atmospheric automatic monitoring platform to monitor the atmosphere in the target area. For pollution factors that cannot be monitored by the automatic monitoring platform, a sampler can be used to collect atmospheric samples in the air and send them back to the laboratory for analysis. The UAV remote sensing system has a strong ability to support safe operations, can enter high-risk areas to work, and effectively avoids the safety risks of monitoring and sampling personnel.
Daily monitoring. Regular fixed-point inspections are one of the main means of daily monitoring and enforcement by the public security department. The traditional fixed-point regular inspection methods require personnel to frequently inspect designated areas, with high labor costs and low inspection efficiency. It takes 3 to 4 to inspect an area at a time. For people, it takes 1 to 2 hours. Only 6 to 8 areas can be inspected in a working day, and there will still be a lot of dead corners. When using a drone for inspection, generally only 2 people are needed, and one area is inspected at a time. Inspection only takes 5-10 minutes, 30 ~ 40 areas can be inspected in a working day, the efficiency can be increased by more than 10 times, and because the drone is high-altitude monitoring, the viewing angle is diverse, the camera is used to scan the ground, and on the ground, Invisible or unclear situations can be seen at a glance from the air, so that more comprehensive image information of the target area can be obtained.
The tethered drone uses a variety of satellite positioning technologies and simultaneously installs a differential GPS system and a single-point GPS system. The differential GPS positioning system can provide positioning accuracy of approximately centimeter level. When the differential GPS fails, the single-point GPS system automatically switches to ensure the normal operation of the system.
The tethered drone flight control has multiple safety measures to ensure the stability of the system.
After the drone data link is abnormal, the drone will automatically land.
The GPS signal is blocked and cannot return to normal for a period of time, and the drone will automatically land.
If the power supply system of the drone fails, the system will automatically switch to backup battery power and land automatically.
Atmospheric monitoring. At present, air pollution is one of the more serious areas of pollution in China. It has seriously threatened people's lives and property. It is urgent to use high-tech means to monitor and prevent environmental disasters or polluting enterprises more effectively. UAVs equipped with atmospheric environmental monitoring equipment can automatically complete the operation. And even if there is an accident, it will not cause direct casualties, which is especially suitable for replacing environmental monitoring personnel or manned aircraft to complete some dangerous tasks. At the same time, due to the mobility of the equipment, it can also improve the efficiency of atmospheric environmental monitoring.
The use of thermal sensors has given drone night vision capabilities, making it a powerful surveillance tool. Drones are able to spot missing people and unfortunate victims in harsh conditions or challenging terrain. In addition to finding victims, drones can drop supplies to unreachable locations in countries that have been damaged by war or disaster. For example, drones can be used to lower walkie-talkies, GPS locators, medicines, food supplies, clothes and water before rescuers move the victims to other locations.
