Types and components of MYUAV police drones
Police UAV has great promotion value in public security information work. With the rapid development of modern science and technology, the deep application of public security information has brought a qualitative leap to the efficiency improvement of police work.
At present, the national public security organs are equipped with more than 5,000 types of UAVs, UAVs have played an irreplaceable role in the pursuit of fugitives, patrol and surveillance, drug shovelling and drug control, anti-terrorism and riot control, traffic management, large-scale event security and social rescue and relief tasks, and have become an important force to serve society and maintain social stability.
Police UAV, different from ordinary UAV, is a police unmanned aircraft, which refers to the UAV as the carrier, equipped with relevant subsystems, and can perform police tasks.
At present, domestic police drones have been widely used in anti-terrorism monitoring, flood rescue and disaster relief, forest fire fighting, riot search, emergency investigation, mass dispersal, large-scale gathering security, rescue and search, traffic patrol and other occasions.
Classification of drones
01 Fixed wing UAV
The fixed-wing UAV relies on the thrust generated by the propeller or turbine engine as the flight power, so it has the characteristics of fast flight speed, flight duration and large carrying capacity. However, due to the large individual size, take-off and landing are easily restricted by the site.
Fixed-wing UAVs are very useful and are generally used when there are large range and height needs, such as highway monitoring, airspace cruise, grassland, forest fire prevention and other fields.
02 Unmanned helicopter
Unmanned helicopter is an unmanned, unmanned vertical take-off and landing rotorcraft flying by radio remote control or autonomous control. It relies on the engine to drive the rotor to generate lift and control force, can take off and land vertically, hover in the air, and can fly flexibly in any direction.
Unmanned helicopters are characterized by long endurance, multi-mission, stability, etc., with relatively low cost, no risk of casualties, strong survivability, good maneuverability, easy to use and other advantages, and are widely used in: Forest fire prevention, earthquake investigation, border patrol, emergency disaster relief, drug control, anti-terrorism, police investigation patrol, public security monitoring, aerial fire investigation, and other police fields.
03 Multi-rotor UAV
Multi-rotor UAV relies on multiple rotors to generate lift force to balance the gravity of the aircraft, so that the aircraft can achieve the effect of take-off, while changing the speed of each rotor to control the stability and attitude of the aircraft, so the multi-rotor UAV can hover and fly at any speed within a certain speed range.
The multi-rotor UAV is small and easy to operate, and can enter a forest with many branches and leaves to observe a target in detail.
The mature application of China's multi-rotor UAV application technology and system solutions makes the multi-rotor UAV platform combined with video, infrared and other monitoring and transmission equipment, through the air to detect and inspect complex terrain and complex structure buildings, scene rescue command, case tracking, fire detection and prevention and control, becoming the most widely used UAV type for urban police aviation.
Police unmanned aerial system composition
The police UAV system is composed of body system, flight control system, communication system, power system, load system, launch and recovery system, ground control system and so on.
The body system mainly includes wing, fuselage, tail, landing device and so on. The structure of the body should fully take into account the aerodynamic, mounting, economic and other aspects, and their size, position, and wing shape will directly affect the operation efficiency and performance of the UAV.
The flight control system is the core part of the UAV, just like the commander directs the aircraft to fly;
The communication system ensures the contact between the ground and the aircraft. The ground can send instructions to the aircraft, and the aircraft can also transmit data to the ground.
The power system can generate pull and thrust to ensure that the UAV rises and flies;
The loading system can facilitate the UAV to mount a variety of functional equipment, to achieve high-altitude shooting, lighting, Shouting, throwing, relay communication, etc.
Launch and recovery devices are mainly used to achieve take-off and landing tasks;
The ground control system mainly completes the setting of the flight mission, monitors the flight status of the UAV, loads the mission data, controls the UAV and the mission, records the flight parameters, records the mission data, etc.
The key technologies involved in MYUAV police UAV are flight control technology, communication technology, obstacle avoidance technology, launch and recovery technology.
