Description

Security light with CCTV Drone on head part for crime prevention and security}

The present invention relates to a security security street light, and in particular, a new security police street security provided with a CCTV drone headlights.

As the society develops and the floating population by region increases, various crime accidents increase. Early response is very important for crimes that occur not only in densely populated cities, but also in small towns and rural areas. Although the central government and local governments have provided manpower expansion and security measures to maintain security, crime prevention and response are limited.

In order to prevent crimes and collect evidence of crimes, unmanned surveillance means such as CCTVs are being installed and the number is increasing.However, even if the number of crime prevention CCTVs is increased, the stability of citizens and the reliability of crime prevention are not increased proportionally. There is also a problem that is not proportional to the number of CCTV. In particular, when a crime situation occurs, crime prevention CCTV is merely a witness, and there is a limit that cannot directly prevent a criminal act or track and arrest a criminal in that situation.

Meanwhile, the existing crime prevention CCTV is installed in a high place, it is difficult to replace, repair, exchange. Security CCTV does not differ in form from general CCTV, and can only be confirmed by the phrase 'Security CCTV' on the sign. Current security CCTV has a problem of insignificant waste of resources due to difficulty in maintenance and repair, and the effectiveness of the actual security function is also inferior due to the lack of awareness of security CCTV.

In the past, a technology for preventing crime using street lamps has been proposed. According to Korean Patent No. 10-1610026 (Hybrid-type security street light system), by installing an image camera, an emergency button unit, a smart pad, a voice call unit, etc. in the street lamp, by pressing the emergency button unit when an emergency occurs, By connecting with the local government and the local police station, it is possible to remotely monitor the current situation and to immediately check the information of the reporter obtained through the smart pad. However, such a streetlight system is biased against crime prevention through a camera and an emergency bell fixed to the streetlight, so it is not much different from the existing CCTV, and it is impossible to shoot a crime scene outside the shooting range. Therefore, there is a limitation that it is difficult to proactively prevent criminal acts, and in particular, it is impossible to track criminals or give practical assistance to arrest.

In addition, a technique for preventing crime using a wireless aircraft has been proposed. According to Korean Patent No. KR 10-1850297 (Wireless Vehicle for Lighting and Shooting), it is free to fly in place and mobile, and at night, it prevents crime by illuminating dark alleys or roads and unhumanized places. A technique for tracking a field or runner is known, and in order to achieve this purpose, one or more propellers are arranged to achieve a stationary flight and a mobile flight, and a body provided at the bottom or the center of the flight to control the flight; And a lighting unit provided in the body or the flying unit to make an illumination, an image unit provided in the body or the flying unit for photographing, a vehicle control unit controlling the flying unit and the image unit, and wirelessly transmitting and receiving to and from the aircraft control unit. A vehicle body adjusting unit is provided. However, this technology is a simple device that illuminates the general technology of drones, which is conventionally equipped with an imaging device, and is not deployed in a specific area, so it is difficult to have a practical effect on preventing crime. In addition, even if the vehicle is moved to a crime place, there is a limit to use it as a security means because it does not solve the problem of charging, placement place and maintenance due to long time flight.

Given this situation, a new system is required to replace or improve security CCTVs to improve security functions and maximize crime prevention. In particular, there is a need for a device that can prevent crime from escalating through a warning when a crime occurs, and improve the efficiency of arrest through tracking of criminals as well as collecting data on criminal activities. In addition, there is an urgent need for a new system that can make the best use of existing social facilities to prevent resource waste and maximize crime prevention.

Since the motor and the rotor are horizontally mounted on the outer surface of the center body, the drone can fly in any direction up, down, left and right, and in this embodiment, it is composed of a six-wing hexa rotor system having excellent stability. In addition, since the length of the rotor bar is variable, it is easy to mount on the street lamp head, and as described later, the rotor bar can be mounted in a non-contact floating manner. In the flight drive, the motor may use a motor capable of performing a drone criminal operation, for example, an efficiency of 1100 g or more of a thrust of 2300 KV 26.8A standard.

The outside and inside of the drone includes a communication unit including various transceivers. For example, it may include a GPS receiver 261, an antenna 262, a crime information transceiver 263, and the like mounted on the central body. The communication unit may determine the location of the drone or identify the location of the streetlight on which the drone is mounted, transmit image information photographed through the drone, and receive and track location information of the criminal. Transmitters used in the communication department use licensed security spectrum with high security and reliability for location of crime reporter and drone location, and error caused by frequency interference using global standard 3GPP-based licensed band frequency. Do not LTE-M type transmitter can be used.

The image capturing unit mounted at the bottom of the center body of the drone includes a camera 222, a gimbal 224 and a protective cover 226 for changing the photographing angle of the camera. The imaging unit can use a 360 degree shootable 4K UHD security camera with gimbals of pitch (-90 degrees to +30 degrees), roll (0 degrees or 90 degrees-horizontal and vertical) to perform CCTV functions. Infrared cameras equipped with a thermal 19mm lens can be used to identify criminals and track subjects, especially at night.

The outer surface of the central body is equipped with a beacon lighting unit for performing a warning light or an illumination function, the beacon lighting unit may include a beacon 231 of a color similar to that of a police car and an RGB LED light 232 for illuminating the beacon. . In addition, a speaker 250 for generating a siren or a warning message is built in the center body. LED lights can be used to visually alert emergency situations and to generate warnings by generating siren through the speaker. In particular, drones can track the culprit and generate warning sounds and lights to prevent crime from escalating and contribute to the organic cooperative operations of security personnel.

In addition, the drone of the present invention may further include a directional microphone (not shown) together with the speaker. The directional microphone allows the drone to receive and transmit the sound of the crime scene to help identify the crime and collect evidence.

In order to supply power to the power generation unit of the flight driving unit and the communication unit, the image photographing unit, the beacon lighting unit, the speaker, a charging battery 240 is built in the central body. The rechargeable battery can be wirelessly charged from the street lamp head as described below. Rechargeable batteries can use, for example, lithium polymer battery 3.7v, 7600mAh (5.0Ah)-25C discharge lithium polymer battery specifications for RC, enabling drones to fly at speeds of 70 to 80 km / h to enable stable criminal arrest operations. It is desirable to use a battery capacity that can travel back and forth between 3.1 and 3.6 km and maintain a flight time of 17 to 22 minutes.

In addition, a magnetic resonance receiver coil 204 for wireless charging is built into the center body of the drone, and a PCB-type control unit which controls the drone's flight, image shooting, battery charging, signal transmission, and communication with the outside as a whole ( 280 may be embedded.

In addition, the security police street lamp of the present invention is a gyroscope sensor 271 for balancing the drone in the center body of the drone, acceleration sensor 272 or geomagnetic sensor for measuring the rotational motion of the drone, translational movement of the drone It may further include a flight control unit including a GPS receiver for measuring the, an ultrasonic sensor (not shown) for preventing the collision of the drone. Precise hovering can be maintained through the GPS receiver, tilt and level can be maintained through the 3-axis gyroscope sensor, inside the building through the 3-axis geomagnetic sensor, and collision with the building or obstacle is prevented through the ultrasonic sensor. can do.

Security police street lamp of the present invention performs a CCTV function in the state of the drone's video recording unit is exposed to the lower center of the head in normal times, when the emergency occurs, the drone is taken off from the head to perform the video shooting with the flight After the emergency situation is released, it returns to the head part.

In order to allow the drone to be stably seated or mounted on the head part and to be able to move quickly from the head part, the structural design of the drone's flight drive part is important. In the present invention, the rotor bar 212 of the drone is designed in a variable structure in which the length is adjusted radially with respect to the central body to enable a structural change in the mounting and dispatch of the drone.

4 is a schematic diagram showing the change in the length of the rotor bar, and it can be seen that the length of the rotor bar 212 of the drone is reduced so that all of the drones are included in the street lamp head 110. The rotor bar of the flight drive may be adjusted in length using, for example, a linear air cylinder or air suspension, in which case the central body has a linear compressor 213 and an electronic control valve (not shown) for varying the length of the rotor bar. ) May be included. When the drone is flying, the rotor bar is expanded to the maximum as shown in FIG. 5 to allow the drone to fly stably.

In the security security street light of the present invention, the head portion serves as a station for charging, while providing a mounting place for the drone. The streetlight head unit which performs the charging station function may charge the battery of the drone by a wireless charging method by magnetic resonance. 6A and 6B schematically show a state in which the drone is wirelessly charged from the street lamp head, and the charging battery is wirelessly charged while the drone is mounted or suspended in the head. To this end, the magnetic resonance transmitting coil 112 is embedded in the street lamp post or the street lamp head and the magnetic resonance receiving coil 204 is embedded in the drone. By using the same frequency at the transmitter and receiver to transfer power using the resonance phenomenon, it is possible to charge in a non-contact manner. By using the magnetic resonance type of wireless charging, it is possible to solve the power supply problem of the drone that requires emergency dispatch, and if the power is insufficient during the operation, it can return to the street lamp and repeatedly charge.

In the present invention, the drone may be mounted on the top surface of the street lamp head, but may be mounted in a non-contact state by magnetic levitation. In this case, the head portion may have an electromagnet 114 embedded in the annular structure, and a permanent magnet 218 may be embedded in the rotor frame end of the drone. FIG. 7 shows a drone mounted in a non-contact floating state in the head portion, and FIGS. 8A and 8B schematically show a magnetic levitation state of the drone. The permanent magnet mounted on the drone does not change the pole to the N pole or the S pole, and the electromagnet installed in the street lamp keeps changing the N pole and the S pole as the current flows. Permanent magnets and electromagnets repeat the process of pulling and pushing each other, which allows the drone to remain floating in a non-contact manner inside the head of the street lamp. The drones remain floating on the street lights by themselves, which reduces the shock transmitted from the head due to external forces such as wind or rain, reduces gas damage caused by external forces, and facilitates emergency dispatch in a suspended state. Arrest can be conducted.

In addition to the non-contact floating state, the head unit controls an electromagnet provided therein so that a drone with a permanent magnet is mounted on the top of the annular structure of the head unit, and is firmly mounted against wind or external impact (by interaction between the electromagnet and the permanent magnet). State can be maintained. In this case, the rotor bar seating groove may be further formed on the top of the annular structure so that the rotor bar of the drone is stably mounted on the head of the annular structure.

Figure 9 is a perspective view showing the landing and dispatch of the drone, when the rotor bar is extended after the flight to return the rotor bar is reduced in the length of the mounted on the streetlight head portion, and then in another emergency situation The rotor bar can be extended while moving out of the head.

These drones are usually installed in streetlights to act as general CCTVs, and in the event of an emergency reporter, the GPS detects the location of the crime and sends it to the relevant location. If you check the culprit after dispatching, you can set it as the subject and track the culprit, and emit a beep and light during the tracking process and send a continuous video to help the police arrive at the location where the drone tracks and help to arrest the culprit. do.

10 is a schematic diagram showing a criminal arrest process according to a drone dispatch.

In ordinary times, the security camera is controlled to take images of street lamps and store the image information in memory or provide them in real time or periodically. When a crime situation or an emergency situation is received at a control station or a competent police station (a), it checks the location information such as the location of the witness or the crime place (b), and transmits the location information to the security police street lamp close to the location (c). . The drone receiving the range related information and the location information immediately takes off from the head and arrives at the crime place (d). In the process, it is possible to continuously communicate with the control station or the police station or transmit video information. When the drone arrives at the scene of the incident input in GPS coordinates, the assailant is set as a subject to be pursued (e).

If a drone is dispatched in an emergency situation, three drones may be dispatched together in a street lamp configured at the nearest location within 180 seconds, the golden time of crime prevention, by using the GPS to identify the location of the reporter. (f). When three drones are composed of a triangular flight, they can chase the assailant to obtain multiple angles of view and deliver more accurate image information to the control station or police officer (g).

If the tracking flight is prolonged in consideration of the maximum travel distance depending on the battery capacity (for example, 3.1 to 3.6 km round trip), drones with low battery capacity can be returned to the streetlight head through the return to home (RTH) system. In this case, another drone may be driven from the nearest streetlight based on the GPS coordinates of the shooter to maintain three tripods.

When the police officer arrives at the crime place and the arrest is completed and the emergency is over (h), the drone returns to the corresponding street lamp through the stored GPS coordinates and is mounted on the head to recharge the battery with the basic monitoring function (i).

CCTV demand is increasing according to the rapidly increasing crime rate, the need for a street lamp system equipped with CCTV drone in the police station and public institutions for more effective crime prevention and criminal arrest operation, the present invention is a It is expected to contribute to the stability and happiness of citizens by raising the level to the next level.

The present invention has been exemplarily described through the preferred embodiments, but the present invention is not limited to such specific embodiments, and various forms within the scope of the technical idea presented in the present invention, specifically, the claims.
