Tethered Hovering Drone System used in the rescue of MU5735 Air Crash of China Eastern Airline

According to CCTV news, on March 21, 2021, China Eastern Airlines passenger plane MU5735 crashed halfway from Kunming to Guangzhou. The crash site of the passenger plane was in Guangxi. After the accident, the local fire department rushed to the accident site for emergency rescue at the first time. At present, the casualties of the accident are still unknown. People from all walks of life involved in fire fighting and rescue are still struggling to search for survivors and the black box of the accident passenger plane Boeing737-800NG.

In the report of CCTV news, we can see that there are many emergency rescue equipment, including emergency lighting, including head mounted flashlight, bracket LED lamp and unmanned hovering lamp. Among them, the most eye-catching is this Tethered Hovering Drone System (Portable High-altitude Hovering Lamp). This type of hovering lamp generally adopts the LED lamp with low power consumption and low heat of UAV, which has reached a high level in terms of lighting range, height and lighting duration.

However, in fact, no matter what kind of lighting equipment is, it is inseparable from the emergency power supply. Especially in the case of such field rescue operations, the emergency power supply must be needed to supply the power, otherwise once the power is cut off, the emergency rescue equipment will not be able to use. Let's take a look at the working principle decomposition diagram of UAV lighting equipment (Tethered Hovering Drone System) (Portable High-altitude Hovering Lamp).

From the above working principle decomposition diagram, we can clearly see that the emergency power supply, as the lowest and most basic power supply system, is the core of the whole Tethered Hovering Drone System (Portable High-altitude Hovering Lamp). Without the whole emergency power supply, the whole emergency rescue equipment will be paralyzed and cannot be used.

In fact, it is not only in this China Eastern Airlines incident that Tethered Hovering Drone System (Portable High-altitude Hovering Lamp) were used. In fact, this emergency lighting and other lighting equipment were used at last year's Zhengzhou rainstorm rescue and disaster relief and other large-scale accident rescue sites, and they were also equipped with high-power and high-capacity emergency power supply.

Emergency power supply, as the core emergency rescue equipment of rescue and disaster relief, is very important. In the future, it will be widely used nationwide and even globally. Then, it can be imagined how huge its market is.
