Application Scenes

Muli County Forest Fire Incident

At about 18:00 on March 30, 2019, a forest fire broke out in Lier Village, Yalongjiang Town, Muli County, Liangshan Prefecture, Sichuan Province. The accident killed 30 people, including 27 firefighters.

According to the statistics of the Office of the National Forest and Grassland Fire Control Headquarters, a total of 2,478 forest fires occurred nationwide in 2018, including 894 large forest fires, 3 major forest fires, and 2 extra-large forest fires. 

The affected forest area was 16,309 hectares,cause huge casualties and property damage.

Communication is difficult and dangerous

The communication infrastructure in the forest area is poor, and mobile phones and wireless Internet access devices are usually unavailable in the deep forest. Firefighters without communication are like blind people.Without guidance, they will endanger the lives of firefighters at any time

The complex terrain of the forest area, the uncertain wind direction, and the thick forest humus layer make it difficult to extinguish the fire, which brings huge difficulties to the rescue

Industry advantage

Unmanned Helicopter

1、The volume of the hanging space is the same, and the price is much lower than that of the helicopter

2、Good mobility, fast loading and unloading on the vehicle, and reaching the rescue scene through vehicle transportation

3、High reliability, even if one engine fails, it can return safely

Electric multi-rotor

The electric multi-rotor drone has a maximum load of 20 kilograms, and the flight time does not exceed 20 minutes, which is much lower than that of 

the oil-powered multi-rotor drone in terms of load capacity and flight time

Market Advantages

Fill the Domestic Gap

The unmanned fire fighting equipment market is currently blank in China

with great potential in the future. The market space is a blue ocean. It faces

 the new fire fighting market and solves the pain points of fire rescue
