Abstract: Drones have gradually entered our lives, and are widely used in various fields. For example, Jingdong Delivery chooses to use drones for operation, or to use drones for geographical environment exploration and terrain mapping, etc. Drones provide favorable support for disaster relief and assistance work in the process of use. At present, a large number of aviation enthusiasts appear in our country, at this time, drones can be used for aerial photography. At present, drones can also be used to transport coal in thermal power plants. Under normal circumstances, coal in thermal power plants is generally stored in the open air, which is easily affected by the external environment, so it is easy to cause spontaneous combustion. This process may bring great economic losses to power generation enterprises, and also affect people's life and property safety. So it makes more sense to use drones inside.
