Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to a fly-type police aircraft system suitable for reconnaissance in complex environments, mainly used for reconnaissance work in scenarios such as narrow indoor places and concealed criminal activities. With the complication of modern policing work, traditional reconnaissance means have many limitations when dealing with scenarios such as narrow spaces and concealed criminal activities. By designing a small, highly maneuverable, and low-noise aircraft system, the present invention can quietly approach the target in a complex environment and obtain detailed information such as the facial expressions and behavioral actions of suspects, thereby improving the efficiency and safety of police reconnaissance. Background Art

[0002] In modern policing work, reconnaissance work faces many challenges. Especially in the reconnaissance of narrow indoor places or concealed criminal activities, traditional reconnaissance means often have problems such as blind spots in the perspective and risks of police casualties. Existing reconnaissance means mainly rely on human reconnaissance, surveillance cameras, etc., but these means have obvious limitations in complex environments. For example, in narrow indoor spaces or concealed crime scenes, it is difficult for police officers to enter or there are significant safety risks; while traditional surveillance cameras cannot move flexibly and it is difficult to cover all possible reconnaissance areas.

[0003] In recent years, with the rapid development of aircraft technology, small aircraft have gradually been applied to police reconnaissance work. However, existing small aircraft still have deficiencies in terms of concealment, maneuverability, and reconnaissance capabilities. For example, most small aircraft are relatively large in size and it is difficult to fly flexibly in narrow spaces; at the same time, they are relatively noisy and are easily detected by the target, resulting in the failure of reconnaissance. In addition, the reconnaissance functions of existing aircraft are relatively single, usually only providing video surveillance and unable to meet the multi-dimensional reconnaissance requirements in complex environments.

[0004] Therefore, it is of great practical significance to develop a fly-type aircraft system that can meet the reconnaissance requirements in complex environments. By designing a small, low-noise, and highly maneuverable aircraft system and integrating various reconnaissance functions, the present invention can conduct concealed reconnaissance in complex environments, provide comprehensive reconnaissance information, and thereby improve the efficiency and safety of police reconnaissance. Summary of the Invention

[0005] The present invention aims to provide a fly-type police aircraft system that can approach targets silently in complex environments, obtain detailed information about suspects, and at the same time possess high mobility, concealment, and multiple reconnaissance functions to improve the efficiency and safety of police investigations. Specifically, the aircraft system of the present invention can conduct covert reconnaissance in complex environments such as narrow indoor spaces and hidden crime scenes, providing multi-dimensional reconnaissance information such as video surveillance, thermal imaging reconnaissance, and sound detection, helping police officers quickly grasp the on-site situation and reduce the risk of investigation.

[0006] 1. Aircraft body design Structural design: The present invention adopts a small multi-rotor aircraft design with an axle distance of about 10 cm, such as a quadcopter or a jet aircraft, to ensure mobility in narrow spaces. The outer shell is made of lightweight and strong carbon fiber composite material, which reduces weight and provides collision protection. The carbon fiber material not only has the characteristics of high strength and low weight but also can effectively absorb impact force to prevent the aircraft from being damaged due to collision during flight.

[0007] Power system: The power system of the aircraft is powered by a micro lithium polymer battery, and the endurance time can reach 5 - 10 minutes. To ensure low-noise operation, the aircraft is equipped with an ultra-small turbo fan engine or multiple micro electric propellers to provide lift and flight speed. The design of the micro electric propellers can not only reduce noise but also improve the mobility of the aircraft, enabling it to fly flexibly in narrow spaces.

[0008] Detection module mounting bracket: An adjustable-angle mounting bracket is designed under the aircraft for fixing detection devices. The mounting bracket adopts a modular design, which is convenient for quickly replacing or assembling detection devices in case of emergency. In addition, the aircraft is equipped with an emergency landing device (such as a buffer airbag) and a redundancy design (such as a dual-battery system and a dual-control system) to improve the reliability and safety of the system. The buffer airbag can provide buffering when the aircraft makes an emergency landing to avoid equipment damage; the dual-battery system and the dual-control system can provide backup support when the main system fails to ensure that the aircraft can return safely.

[0009] 2. Detection devices Optical detection equipment: The aircraft is equipped with a high-resolution camera with an infrared filter switching function to achieve visible light imaging during the day and infrared imaging at night. The high-resolution camera can capture the subtle expressions and behavioral movements of targets, and the infrared filter switching function can conduct effective reconnaissance in nighttime or low-light environments. In addition, the aircraft is equipped with a high-sensitivity thermal imager that can detect the thermal radiation differences of objects to discover hidden personnel or objects. The application of the thermal imager enables the aircraft to discover hidden targets in complex environments, such as personnel hidden behind walls or under shelters.

[0010] Sound Detection Device: The aircraft is equipped with a high-sensitivity microphone array for detecting abnormal sounds. The microphone array can capture weak sound signals and identify abnormal sounds, such as footsteps and conversations, through sound analysis algorithms. The addition of the sound detection device enables the aircraft to provide sound information on the basis of visual reconnaissance, enhancing the reconnaissance ability.

[0011] Data Transmission and Processing: The aircraft adopts high-speed and stable wireless transmission technology, combined with a transmission protocol with strong anti-interference ability, to ensure the stability of data transmission in complex building environments. The wireless transmission technology can transmit data such as videos and sounds collected by the aircraft to the control terminal of the police officers in real time, ensuring the timeliness and accuracy of information. In addition, the aircraft is equipped with a data processing module, which can perform preliminary analysis on the collected data, such as face recognition and behavior analysis, to help the police officers quickly grasp the on-site situation.

[0012] 3. Control and Operation Remote Control: This invention is equipped with a dedicated remote control device with an intuitive operation interface. For example, the joystick is used to control the flight direction, and the button is used to control the switch of the detection device and mode switching. The design of the remote control device takes into account the operating habits of the police officers to ensure simple and intuitive operation. In addition, the remote control device is also equipped with a display screen, which can display the flight status and reconnaissance information of the aircraft in real time, helping the operator better grasp the flight situation of the aircraft.

[0013] Autonomous Flight and Obstacle Avoidance Function: The aircraft is equipped with advanced autonomous flight algorithms and obstacle avoidance sensors (such as lidar or binocular vision sensors), which can achieve autonomous flight and automatic obstacle avoidance. The autonomous flight algorithm can automatically plan the flight route according to the preset path or target point to ensure that the aircraft can efficiently complete the task. The obstacle avoidance sensor can detect obstacles around the aircraft in real time to avoid collisions and ensure flight safety.

[0014] 1. Strong Concealment: The aircraft is small and has low noise, enabling it to conduct covert reconnaissance in complex environments and avoid being detected. Its low-noise design and concealed appearance allow it to approach and obtain information without the target being aware.

[0015] 2. Multifunctional Reconnaissance: Integrates multiple reconnaissance functions, such as video surveillance, thermal imaging reconnaissance, sound detection, etc., to provide comprehensive reconnaissance information. The multifunctional reconnaissance equipment enables the aircraft to conduct effective reconnaissance in different environments, meeting the multi-dimensional reconnaissance needs in complex environments.

[0016] 3. High Maneuverability: The high maneuverability and modular design of the aircraft enable it to enter narrow spaces and quickly assemble a temporary aircraft, improving the reconnaissance efficiency. Its small fuselage and flexible flight ability allow it to conduct reconnaissance in narrow indoor spaces, ventilation ducts, etc., where conventional aircraft are difficult to reach.

[0017] 4. High reliability: Equipped with redundant design and emergency landing devices to improve system reliability and safety. Designs such as dual-battery systems, dual-control systems, and buffer airbags ensure the safe operation of the aircraft in complex environments.

[0018] 5. Convenient operation: Can cooperate with devices such as police AR glasses, platform screens, and mobile phone APPs to achieve convenient data transmission and real-time monitoring. Police officers can view the information collected by the aircraft in real time through multiple devices to ensure the timeliness and accuracy of the information. Specific implementation methods
