The application of drones in emergency rescue
Emergency communication support
Targeted restoration of public network communication in disaster stricken areas: Equipped with airborne satellite communication equipment and airborne public network base stations, it maintains link communication with satellites through high-altitude flight, uses 4G/5G communication technology, and transmits business data back to the operator’s core network through satellite transmission. Targeted restoration of public network communication in disaster stricken areas provides voice, SMS, and internet services for users in disaster stricken areas.
Building an emergency communication private network: equipped with airborne satellite communication equipment, airborne PDT cluster base stations, airborne broadband self-organizing network equipment, etc., to quickly build an emergency communication private network for public security, emergency and other departments, realizing the real-time exchange of information and instructions between the command center and frontline search and rescue personnel, and ensuring the smooth progress of rescue work.
On site monitoring of disaster situation
Not affected by terrain such as road interruptions caused by disasters, it can quickly switch areas according to emergency support needs to meet sudden coverage requirements. The unmanned aerial vehicle rescue platform is equipped with electro-optical pods, airborne personnel search and rescue payloads, etc. Realize large-scale and fully controllable visual flight capabilities, providing strong support for the command center to clarify the key directions of rescue and disaster relief in a timely manner, and deploy post disaster rescue work.
On site rescue support
In complex environments where manpower is insufficient or inaccessible, unmanned helicopters are used to carry emergency supplies such as medical, food, and communication equipment, enabling rapid supply of emergency supplies to disaster stricken areas and reducing loss of life and property. It can also be equipped with electro-optical pods, lighting equipment, and loudspeakers, corresponding to the application of on-site situation inspection, night lighting, and shouting and preaching.
Forest and grassland fires
Forest and grassland fires are highly sudden and destructive. Once a major forest and grassland fire occurs, it will seriously damage the ecological environment, cause huge economic losses, and affect social stability.
By using unmanned aerial vehicle rescue platforms to carry different payloads, applications such as fire observation and analysis, personnel search and rescue, material transportation, fire extinguishing, and real-time monitoring of disaster situations can be realized, providing decision support for forest and grassland fire rescue work.

Drones are unmanned aerial vehicles (UAVs), which are aircraft without human pilots. In recent years, with the rapid development of drones, more and more industries have also integrated into the drone market, and the types of drones have gradually diversified. So, what are the types of drones? Below we will introduce it.
What are the types of drones? (Comparison of advantages and disadvantages)
According to different aerial platforms, there are four main types of drones: fixed wing drones, multi rotor drones, vertical takeoff and landing fixed wing drones, and unmanned helicopters. Below, we will first introduce the advantages and disadvantages of four types of drones in the form of a table:

1. Fixed wing unmanned aerial vehicle
   Fixed wing unmanned aerial vehicles have fixed wings and rely on the wind passing over the wings to provide lift.
   The advantages of fixed wing drones are fast speed and long range.
   The disadvantage is that the takeoff and landing site is limited and requires runways or manual throwing, while catapult takeoff and landing can only be done by sliding or parachuting.
2. Multi rotor unmanned aerial vehicle
   Multi rotor unmanned aerial vehicles are flight platforms composed of multiple power systems, commonly including quadcopters, hexacopters, octrons, and even more rotors.
   The advantages of multi rotor drones are relatively simple operation, vertical takeoff and landing, low requirements for takeoff and landing sites, and the ability to hover at any time. The disadvantages are slow flight speed and short endurance.
3. Vertical takeoff and landing fixed wing unmanned aerial vehicle
   Vertical takeoff and landing fixed wing unmanned aerial vehicles take off and land in a multi rotor manner and fly in a fixed wing manner. Vertical takeoff and landing fixed wing unmanned aerial vehicles integrate the advantages of both multi rotor and fixed wing systems.
   It combines the advantages of safe and convenient vertical takeoff and landing for rotary wing aircraft and fast speed and long range for fixed wing aircraft, with low requirements for takeoff and landing sites and good maneuverability.
   Because it can take off and land vertically, maintenance costs are higher, and compared to fixed wing drones, the range needs to be reduced. Due to the addition of propellers, the load capacity needs to be reduced.
4. Unmanned helicopter
   Unmanned helicopters rely on one or two main rotors to provide lift. Unmanned helicopters can be widely used in industries such as oil inspection, geographic surveying, highway inspection, police security, agricultural and forestry environmental protection, and forestry testing.
   The advantages of unmanned helicopters are small requirements for takeoff and landing sites, ability to hover in the air, high load capacity, and long endurance.
   The disadvantage is that the structure is relatively complex and the control difficulty is also high.
