"Eyes" And "Brain" Of Smart City

A heavy rain on July 21 brought the city of Zhengzhou, Henan Province, to a standstill. The interruption of communications and roads made the rescue work more difficult. The emergence of UAVs has turned all this around.

China's self-developed pterosaur-2h emergency rescue UAV system was dispatched to restore the 50 square kilometer mobile network communication in Henan. Geely Technology Group's Wofei Changkong UAV, in the flood also performed eye-catching. With the advantages of vertical take-off and landing, ultra long flight time and intelligent control, UAV has warned several times of secondary disasters such as bridge break and pollution, providing strong support for local departments to make accurate and efficient rescue decisions. At the same time, relying on the powerful "urban emergency and flood information platform", Wofei Changkong team carries out real-time three-dimensional modeling, quickly completes the inundation analysis of key areas, and forms the overall solution of emergency rescue situation awareness system.

This is just the tip of the iceberg for UAVs to participate in emergency rescue. More and more "eyes" and "brains" of smart cities are being played by UAVs.

Geely technology has been deeply engaged in industrial grade UAVs for many years. All its UAVs are driven by pure electric power with strong performance, leading the same level in endurance and load performance. It has been widely used in public security management, river cruising, medical rescue, urban fire protection, environmental protection and other fields.

Taking xc-25 double headed dragon UAV as an example, the product has a pure electric endurance of up to 6 hours and a maximum load of 6kg. It is the only pure electric fixed wing UAV in the industry that can still fly for 2 hours after carrying a 1350m range lidar. Moreover, the key system of the UAV adopts redundancy design and self-developed intelligent flight control algorithm, which can not only work in windy days, but also operate efficiently and stably under adverse factors such as low temperature, high altitude and strong electromagnetic interference. The highest take-off and landing altitude is 4500 meters, which is suitable for many special environments such as desert, ocean and plateau.

In the early morning of December 17, 2020, xc-25 UAV undertook the search work of chang'e-5 reentrant after landing in Siziwang Banner, Inner Mongolia, and appeared for the first time in winter. Generally speaking, low temperature environment will have a significant impact on the endurance of pure electric UAV. At that time, the outdoor temperature of Siziwang Banner was as low as - 30 ℃. However, xc-25 UAV used intelligent battery technology to search the target area for 4 hours, which strongly supported the staff's search work in the ice and snow world of nearly 20000 square kilometers.

In addition to its excellent performance, Geely technology's UAV has another advantage of intelligent level. Its AI recognition capability supports the automatic identification and tracking of personnel, vehicles and other targets. Once confirmed, it can follow the flight automatically without external intervention. In addition, when the power consumption is reduced or the data link is interrupted, the emergency disposal mode will be automatically started, and it can return to the take-off point independently and safely. In Yongcheng, Henan Province, Wofei Changkong team cooperated with local police to help track illegal vehicles such as overloading in real time.

At present, Geely technology is actively exploring the city level 3D modeling solution. The three-dimensional mapping of urban area can be combined with urban planning display, urban disaster early warning, emergency simulation and other scenes. At present, the industry is exploring the optimal technical path and product solutions in this field, but there are few large-scale 3D modeling projects for city level in the market. Wofei's advantages of pure electric, long endurance and high stability make it stand out in the industry. Up to now, it has completed data acquisition and 3D modeling work in several key areas including Sichuan, Yunnan, Henan, etc.
