With the rapid development of unmanned aerial vehicles, especially industrial unmanned aerial vehicles, police unmanned aerial vehicles (hereinafter referred to as police unmanned aerial vehicles) have been widely used in police work, effectively solving some of the previous public security work Difficult tasks have been reduced from complexity to simplicity, and they have exerted good social and economic effects in a variety of combat tasks such as anti-terrorism, forest fire prevention, emergency air defense, banned drug eradication, large-scale event security, and mass incident handling.
First, let me explain the difference between police drones and ordinary drones:
There are three main differences between police drones and ordinary consumer drones.
The first difference is the problem of electromagnetic dissipation. Because drones mainly transmit instructions via radio, the instructions of consumer drones are easily detected by nearby enemy electronic systems when they are transmitted. "It is equivalent to the drone just taking off or arriving at the target, the opponent will know immediately It has lost the significance of unmanned aerial vehicles to conceal the enemy.”
The second difference is that there is a gap between the voyage and the effective time spent in the air. Taking into account the distance of the reconnaissance area, even small military drones must last for more than a few hours. Otherwise, after deducting the time spent on the journey, the reconnaissance time over the target is very limited. Therefore, the battery life of ordinary consumer drones from tens of minutes to one or two hours is not of much practical significance.
The third difference is the load capacity. Military and police drones are now mainly used in reconnaissance and monitoring. Whether they are equipped with photoelectric or infrared equipment, the weight of such electronic pods is usually more than several kilograms, far exceeding the effective carrying capacity of consumer drones.
Next, the following police drone applications：
1.The images of the disaster area obtained by using drone aerial photography are becoming an important means of emergency protection for disaster relief surveying and mapping. The human-machine aerial photography of the disaster-stricken area and providing the latest first-hand images are of great significance to the race against time for post-disaster rescue work.
2.Modern security policing is becoming more and more onerous, and it is very urgent to strengthen modern police equipment, especially aviation police equipment. With the development of unmanned aerial vehicle technology, many police flight tasks can be completed by unmanned aerial vehicles. Due to their unique functions, low cost, and convenient use and maintenance, they have become an organic part of police aviation equipment. UAVs have been used for daily policing tasks such as aerial patrol, rescue, event security, fire protection, and emergency handling.
3.Environmental monitoring: The air, soil, vegetation and water quality conditions can be observed by drones, and the development of sudden environmental pollution incidents can also be quickly tracked and monitored in real time; the environmental supervision department uses drones equipped with acquisition and analysis equipment to cruise in specific areas , Monitor the exhaust gas and wastewater discharge of enterprise factories to find pollution sources; use flexible-wing drones with catalysts and weather detection equipment to spray in the air to eliminate haze in a certain area.
There are many more functions of police drones.
In the future, science and technology will become more and more advanced, and the functions and effects of drones will become more and more significant. Let us look forward to it.
