Fourteen years have passed since the "5.12" Wenchuan earthquake. This is a short period of time, as short as the panic and loss between the shaking of the earth and the mountains, just like yesterday; but it is also long enough to make the new generation of aviation rescue forces full of wings.
This incident has greatly touched the people involved in aircraft, communications, and emergency response.
Li Yidong, chief designer of the Aerospace Wing Loong series and chief designer of AVIC (Chengdu) Unmanned Aerial Vehicle Systems Co., Ltd., said that at that time, many people were thinking about whether they could use long-range, long-distance drones to observe the local area. At the disaster site, establish a communication network. However, limited by the drone and communication technology at the time, the idea has not been able to land. Until the domestic 5G communication and drone technology gradually matured in the past few years, this idea finally came to fruition.
The heavy history has left untold pain, and the seeds of countless innovations have been planted, which has prompted the rapid development of science and technology. In recent years, with the addition of new aviation rescue forces, we continue to explore broader application strategies, integrate and innovate wireless mobile communication means with uavs, satellite communication systems and emergency command systems to provide emergency communication for large disaster sites. , real-time observation and on-site command. Let the post-disaster area no longer become an "isolated island", let the airborne soldiers no longer have to blindly parachute under the circumstances of unknown weather conditions, uncertain ground conditions, and lack of navigation, and let the emergency rescue channel open as soon as possible...
From scratch to iterative innovation, drones have gradually become an important role in my country's emergency rescue system and exert their huge potential by virtue of their advantages such as fast response speed, small space constraints, and strong rescue capabilities. Although the emergency rescue of multi-rotor UAVs now covers various rescue tasks such as fire fighting, medical rescue, emergency transportation, and search and rescue, due to the low flight altitude, short stay in the air, and limited take-off weight, it is still unable to match the Compared with large fixed-wing mid-altitude long-endurance UAVs with large carrying capacity and high scalability.
In more complex dangerous situations, large fixed-wing UAVs can be equipped with corresponding mission loads to realize functions such as 3D map drawing of the disaster area and live broadcast of the disaster area in real time, so that the headquarters can be informed of the situation of the disaster area, so as to deploy corresponding rescue activities. Its commonly used task load equipment for emergency rescue mainly includes synthetic aperture radar, optoelectronic pod, emergency communication support pod and satellite antenna.
Among them, Synthetic Aperture Radar (SAR) has the ability to penetrate clouds and fog, and monitor all day and all day. It can directly observe surface information through clouds and achieve meter-level resolution observations, which can help people quickly understand the impact of disasters in target areas. The optoelectronic pod can act as a scout, complete target detection, search and tracing, and perform night operations.
The emergency communication support pod is mainly responsible for communication tasks. It includes four parts: PDT airborne base station that provides private network communication services for the disaster area, CCD aerial survey camera with high-precision imaging technology, and convenient deployment of broadband ad hoc network equipment and public network mobile communication base stations. Satellite antennas are used to receive signals from satellites.target drone
Today, large fixed-wing long-endurance UAVs represented by "Wing Loong" have actually participated in emergency disaster relief work. When we respond to disaster relief, we can confidently say that we have plans and are available! And high-end drone brands such as "Wing Loong" are still developing and innovating, forging ahead, and effectively promoting the application and development of emergency rescue drones, escorting the safety of the country and society!
