Overview
Unmanned Aerial Vehicle (UAV) usually refers to unmanned, autonomous propulsion, controlled by radio remote control or its own program, using aerodynamic carrier to fly and reclaiming reusable aircraft. In 1917, the UK successfully developed the world's first drone. In the early 1960s, the United States first used drones for military reconnaissance. Since then, drones have participated in the Vietnam War, the Middle East War, the Gulf War, and the Kosovo War. In its military operations against Afghanistan, the United States launched 115 "Halfa" anti-armored missiles on 12 hollow tactical drones, the Predator Predator (Fig. 1), and directed laser-guided bombs for manned aircraft. Attacking the target 525 times, the first drone was used to attack the battle. There are currently hundreds of models of drones in more than 30 countries including the United States, Canada, Germany, the United Kingdom, Austria and Russia. UAVs are far more effective and efficient than human-machines in performing many tasks. In addition to military use, drones have a very broad application prospect in the police and civilian fields.
UAV features
UAVs can gradually replace manned machines in various application fields, and are greatly developed and widely used, which is inseparable from its own advantages. Compared with manned aircraft, it has the following characteristics:
1. Light weight and small size
Among the world's more than 300 types of drones, 66.9% of the take-off weight does not exceed 200kg, 77.4% of the weight is less than 500kg, the takeoff weight is less than 2000kg less than 10%, and no more than 10,000kg. The speed of take-off aircraft is more than 10,000kg, and some even exceed 60,000kg. The maximum size of the drone (except for the long-life aircraft) generally does not exceed 10m, the maximum size of more than half of the drones is less than 5m, and the maximum size of the aircraft is generally more than 12m.
2. Low cost
The price range of small and medium-sized drones is between 10,000 and 1 million US dollars, of which 24% are under 100,000 US dollars, 65% are between 100,000 and 400,000 US dollars, and there are many small ones. The drone is under $10,000. In contrast, manned aircraft worth millions to tens of millions are much more expensive. In addition, drones are much lower than manned machines in terms of driver training and fuel consumption.
3. High mobility
The drone does not need to consider the carrying capacity of the person, but some people must consider the carrying capacity of the person and limit the maneuverability.
4. Adaptable
The take-off and launch of the drone is relatively simple, flexible and maneuverable, and can be carried by the ground, the ship, or the aircraft to the air. When launching on the ground, it can be launched by fixed or mobile launchers. The take-off distance is generally less than 300m. The manned aircraft takes off at a distance of more than 1000m, and the requirements for the runway are also high. In addition, the recycling of drones is relatively simple and can be recovered with parachutes or interceptors, which creates favorable conditions for the flexible and maneuvering of missions.
5. High security
UAVs can perform missions in dangerous areas where people are threatened. They can work in complex and harsh weather conditions or in hazardous areas with nuclear, biological and chemical effects. They can fly continuously for long periods of time.
Application of drone in police security field
With the high-definition camera that is carried, you can take uninterrupted picture capture, capture image data, and transfer the acquired information and images back to the ground. It can be used for anti-terrorism and stability. In the event of unexpected events or catastrophic violence, real-time live video images can be quickly transmitted and transmitted to the commander for scientific decision-making and judgment.
(1) Application in the field of traditional public safety
Traditional public security areas include counter-terrorism, handling mass incidents, major event security, and searching for criminal suspects.
In the event of a terrorist attack or hostage hijacking, the drone can replace the police force in the first time and approach the scene of the incident. The first scene can be returned to the headquarters in real time through airborne equipment such as visible light video and thermal imaging observation. Develop an action plan to provide a basis for decision making.
When a mass incident occurs, the small drone can take advantage of rapid response, air mobility and flexibility, track the development of the event in real time, and help the command center to implement uninterrupted command processing. After the installation of the airdrop device, the small drone can also deliver special items, such as spreading flyers and transmitting information to the ground personnel; the small-rotor drone can send voice messages and transmit government information by adding tweeters.
In large-scale events, small drones can provide high-definition images from the air to the ground, and can be quickly maneuvered to any area needed to search for suspicious persons and vehicles on the ground to provide strong air intelligence. In addition, small drones can be used in search operations for specific target areas and specific people. For example, an infrared thermal imaging video capture device is installed in a small drone to perform a scanning flight search for criminal suspects hiding in the jungle.
(2) Application in the field of border defense
Small UAVs are characterized by high maneuverability and long-haul time. By setting up flight routes through ground station software, efficient border patrols or smuggling of private areas can be achieved.
In addition, in Sichuan, Yunnan and some remote mountainous areas in China, there are still cases of growing illegal crops such as opium poppy. The small-scale fixed-wing UAV is equipped with spectrum analysis equipment to carry out regular scanning monitoring flights to relevant areas, which can be realized quickly and efficiently. Regulatory purposes for special areas.
(3) Application in the field of fire protection
The drone equipped with infrared thermal imaging video acquisition equipment can sensitively respond to the heat source in the forest area. By collecting thermal imaging images, it can quickly analyze the small micro-fire points or heat sources on the ground, so as to realize early control and disaster Losses are minimized.
When a fire occurs in a high-rise building, the ground personnel often cannot observe the personnel inside the building. In this case, the multi-rotor small drone is used to fly to the fire floor, and the internal condition of the building can be observed in real time through the onboard video system. Guide firefighters to carry out effective search and rescue.
In the event of natural disasters such as earthquakes and floods, small UAVs can be deployed quickly, returning high-definition video and high-precision pictures in real time, helping commanders understand the disaster situation, guiding the ground search and rescue forces to rescue trapped personnel in time, and gaining valuable time for disaster relief.
(4) Application in the maritime field
When a shipwreck occurs, the drone has an incomparable advantage over traditional sea-going vessels. The drone equipped with real-time high-definition video capture and transmission equipment, centering on the location of the shipwreck, according to meteorological and hydrological conditions, scanning the flight route through ground navigation, can find floating survivors in time, and guide the surface vessels to rescue.
In addition, for key waterways and key waters, the maritime department can use drones to monitor the discharge of past vessels and timely discover and collect evidence for illegally discharged vessels.
Advantages and specific performance of drones in police security activities
Advantage:
1. Respond quickly, quickly reach the scene, and observe the whole development at the commanding heights;
2. Record the development process in a timely manner at the best angle and provide the most powerful evidence for post-processing;
3. In some vicious violent conflicts, direct use of drones into chaotic areas for monitoring to avoid casualties;
4. In the process of violent confrontation or martial law with the gangsters, the specific situation of the culprits can be understood at zero risk;
5. In some enveloping arrests, unmanned helicopters can monitor the situation inside the enclosure at high altitudes, providing commanders with real-time and effective information.
Specific performance:
1. UAVs can be used to handle emergencies
(1) Collecting on-site data, and quickly transmitting the visual and audio information of the scene to the command center to track the development trend of the event for the commander to make judgments and decisions (airborne electronic eyes). In many cases, street surveillance equipment will be destroyed by lawless elements, making it impossible for us to understand the incidents at the scene of the incident. The drone's onboard camera is completely unaffected. It can be deployed quickly after reaching the scene. On-site observation, with irreplaceable role and air superiority unmatched by general monitoring equipment
(2) In the state of media failure, spread flyers and transmit information to the masses. When some large-scale riots occurred, it was difficult to control because of the large number of people participating in the event and the lack of reason. If necessary, the drone can be used to broadcast flyers, to transmit relevant information to the masses on the spot, to guide the masses to cooperate with the government's rescue actions, or to disperse the demonstrators and release dispersing equipment.
(3) Conducting an air call, passing a speech by the government leader and expressing the police's intentions. Unexpected incidents are uncertain. If you can't use normal propaganda tools to communicate with the masses during the disposal process, you can use the drones to carry out sound-sounding equipment to scream on the scene and convey the correct direction of public opinion.
(4) As a communication relay, the data transmission link of the monitoring area is maintained. The communication equipment for emergency police needs to rent satellite lines to declare in advance, and the procedures are complicated. Due to the large number of blind spots in the high-rise communication signals, the signal is often not transmitted to the command center in time, causing the decision to lag. The small communication equipment carried by the drone can act as a low-altitude satellite, providing an uninterrupted signal link to the ground, enabling the command system to receive detailed warnings of the scene in time.
In practical applications, a complete intelligent unmanned aerial vehicle police integrated emergency system includes: special police vehicles equipped with drones, unmanned reconnaissance aircraft, unmanned communication relays, and drone signal ground receiving stations. The data transmission processing system, the drone console, the ground station monitoring station, and the special communication equipment for the drone. All equipment can be integrated into a police car to respond quickly to sudden alarms.
2. UAVs use flexible and flexible investigative advantages in disaster relief
In the event of a fire or other accident, the drone can arrive at the scene at the first time and transmit the live image data back to the ground command center in time to provide first-hand information to the commander. When the fire broke out in the Jiguanshan forest in Hebei Province, the drone returned the scene image of the fire scene in just 6 minutes, setting a remarkable battle for the suppression of the fire.
3. UAVs in the air to detect large security nets
In large-scale events, gatherings, etc., the effect of ground inspections is easily limited due to complex terrain, numerous road branches, and insufficient human resources. The drone is used for aerial video surveillance inspection, and the target image is transmitted to the on-site command in real time, which strongly supports ground command and dispatch.
4. UAV anti-drug investigation
Due to the large cruising radius, low cost and flexibility of the drone, it can often play a greater role in anti-drug investigation. For example, in 2010, the Beijing police used unmanned survey aircraft and police helicopters to conduct aerial inspections and find similar poppy cultivation in the mountainous areas of the surrounding counties of Beijing. They first used drones to inspect and take photos. Through the drone search, they can automatically take a set of photos every 500 meters. The photos can reach 21 million pixels, and each photo can cover 3 square kilometers. Everything is done without any omissions in all illicitly cultivated opium poppy. Once the suspected drug original plant was discovered, police helicopters and related personnel were dispatched to the area for detailed investigation. This "air-defense" operation based on the characteristics of the growth cycle of the original plant of the drug, fully exploited the advantages of the maneuverability and flexibility of the drone, and found and attacked the illegal cultivation of drug plants from the source.
5. Unmanned reconnaissance aircraft can quickly find criminals and missing persons
Compared with the ground police force, the drone has the advantages of low cost, high efficiency and good effect in quickly finding and locating criminal suspects and missing persons. Currently, the Houston and Miami police departments have incorporated the "Eagle Shadow" new unmanned reconnaissance aircraft into the arsenal to help the police find suspects and missing people. The drone can be photographed with a thermal camera at an altitude of 200 meters above the ground, monitoring everything that happens on the ground, helping the police find criminals, suspects and missing people in the fastest time possible.
6. Drones for traffic management
The drone can grasp the road traffic capacity and traffic order from the air during the peak hours of commuting, heavy traffic accidents, and major security activities, and quickly and accurately alert the road blocking points and card points for analysis and disposal by the traffic police department. Decisively make shunt instructions and intelligent management.
Status and prospects
At present, public security agencies throughout the country have applied drones to some aspects of police activities and achieved good results. The application process of the drone has experienced a process from fixed-wing to unmanned helicopter to multi-rotor from the use of the model; from the application point of view, it has been developed from the initial aerial video and aerial photography. This is undoubtedly a trend in the systematic research, processing and application of aerial photography results. Today, as drone technology becomes more mature and progressive, how to apply drones more deeply to all areas of police activities, in addition to the UAV equipment itself, it is more important to combine the depth of business of each police itself. Customized drone tactical combat application solutions and the full development and utilization of supporting software application systems.
