Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a multifunctional drones 15 and a drones charging apparatus used for intelligent video surveillance according to an embodiment of the present invention. 4 is a block diagram showing the functional configuration of the drones 15 shown in Fig. 1. Fig.

Basically, the multifunctional drones 15 according to the present embodiment are capable of running in a predetermined path and patrolling or moving in a predetermined path, or can fly directly to a target point and perform a mission in response to a dispatch command inputted from the outside when an emergency situation occurs . Mission fulfillment includes the function of photographing various disaster situations and transmitting them to the control center or operator or tracking the escapees.

In addition, the drones charging apparatus includes a dron station 13 installed at the upper end of a column 11 vertically installed on a road periphery, such as a streetlight, and waiting for a missioned dron to dock. The dron that landed on the drones 13 is connected to the stratified charge apparatus (21 of Fig. 3A) in the drones 13 and is supplied with a charging current. It is a matter of course that the landing of the multifunctional drones 15 is carried out by the mutual response signal between the drones 15 and the charging device 21. [

The multifunctional drones 15 according to the present embodiment include a drones 15a having a connecting portion 16g, a photographing portion 15f provided at a lower side of the drones 15a, And a beacon 15g located at the upper portion.

The multifunctional drones 15 will be described in more detail with reference to FIG.

4, the multifunctional drones 15 include an information input unit 16a, a control unit 16b, an alarm output unit 16c, a communication unit 16k, a photographing unit 15f, an analysis unit 16e, A distance sensor portion 16f, a battery 16h, and a connection portion 16g.

The information input unit 16a is a unit for inputting a patrol route to the drone 15. In other words, it is the part where the drone's patrol mission Dashron 15 enters the flight path to pass. It goes without saying that the geographical coordinates can be input through the information input unit 16a.

In addition, the control unit 16b controls all operations related to the drone as well as the flight control of the drones 15. The control unit 16b is connected to the communication unit 16k and receives various signals coming through the communication unit 16k and performs a control operation based on the signals.

The alarm output unit 16c operates when an emergency occurs and informs people on the ground that the situation is an emergency, and acts as an ambulance or a siren of a patrol car. The alarm output unit 16c includes a warning light 15g, a speaker 15h, and a light output unit 15k.

The warning light 15g mainly operates when the drones 15 are flying at night. The speaker 15h also plays a role of notifying the occurrence of a situation or outputting sound. The light output section 15k illuminates light to a road, a building, or an escapee. The light to be irradiated may be a laser beam.

The communication unit 16k transmits the radio signal inputted from the control center or the operator to the control unit 16b or receives the information acquired by the photographing unit 15f and the analysis unit 16e and transmits the radio signal to the control center or the operator .

The photographing unit 15f photographs the surrounding situation while the drones 15 are flying, and may include a general camera 15d and a thermal imager 15e. The general camera 15d is a camera mounted on a general drones. The general camera 15d is mainly used during the daytime. The thermal imager 15e senses and imaged heat using infrared rays, and can be used very usefully at night or when a fire occurs. The image file photographed by the photographing unit 15f is transmitted to the outside via the communication unit 16k.

The analysis unit 16e takes charge of position analysis and image analysis. The location analysis analyzes the current location of the drone 15 and the location of the object to be photographed, and utilizes nearby beacons, a Wi-Fi communication network, or a GPS satellite.

Image analysis is to compare the images taken with the images that are recorded in the drone itself. For example, a process of collating the photographed face of the suspect with the face of the receiver in the data.

The distance sensor unit 16f also serves to sense the distance between the current drones 15 and the point of interest. Such as the distance between the drones and the fire scene, or the distance between the drones and the fugitive. The optical output unit 15k may be utilized for the distance sensing. A technique of sensing a distance using a laser beam is already known.

The battery 16h is charged by a power supplied via a connection portion 16g, which will be described later, as a rechargeable battery. The connection portion 16g is physically connected to the power supply terminal 13f in the course of landing the drones 15 on the drones 13.

Referring again to FIG. 1, it can be seen that a plurality of propellers 15b are installed above the drone body 15a. The propeller 15b is symmetrical with respect to the center of the drones 15a and rotates through the motor 15c to generate lift. The rotation speed of the motor 15c is controlled by the control unit 16b.

In addition, the power supply terminal 13f is connected to the power line 13h. The power line 13h supplies the charging power to the drones as a power line drawn into the column 11 after branched from the underground power line, for example.

2 is a view for explaining a connection method between the multifunctional drones and the drones shown in FIG.

As described above, the drones 13 are atmospheres waiting for the drones to be mounted. In addition, power is continuously supplied to the rechargeable battery 16h while the drones 15 are waiting on the drones 13a and 13b.

Referring to Fig. 2, the drones 13 have support arms 13b on which the drones 15 are wound. The support arm 13b extends horizontally to provide a docking space 13a therebetween.

The mounting space 13a is a space portion opened in upper and lower portions and one side direction, and a portion of the drones 15 is accommodated therein.

In addition, a pivotable door 13c is located on a surface of the drones 13 facing the stationary space 13a. The pivotable door 13c is a plate-like plate supported by an elastic hinge (13d in Fig. 3A), and is rotated by an external force to be opened. The normally-rotatable door 13c is closed.

The connecting portion 16g of the drones 15 has a charging terminal case 15m. The charging terminal case 15m is a box-shaped case protruding laterally from the drones 15a and has a door 15n at a projecting end face. The door 15n is also a door having an opening / closing system similar to the turning type door 13c, and is in a closed state when the drones 15 are flying.

Particularly, the charging terminal case 15m pushes the pivotable door 13c to enter the internal space (13e in Fig. 3A) while the drones 15 approach and dock to the drones 13, (15q in Fig. 3A) is connected to the power supply terminal 13f.

3A to 3D are views for explaining a configuration and a connection method of the charging device 21 of the multifunctional drones 15 according to the present embodiment.

3A, an inner space 13e is provided in the interior of the drones 13, and a power supply terminal 13f is provided in the inner space 13e. The power supply terminal 13f is accommodated in the connection guider 13g as a power accessory connected to the power line 13h. The connection guider 13g is a member made of synthetic resin or ceramic and guides the coupling of the charging terminal 15q to the power supply terminal 13f.

The inner space 13e is opened and closed by a pivotable door 13c. The pivotable door 13c is a door which is supported by the elastic hinge 13d so as to be symmetrically arranged above and below, and rotates in the direction of arrow a in Fig.

In addition, a charging terminal 15q is provided in the charging terminal case 15m on the side of the drones 15a. The charging terminal 15q is internally connected to the battery 16h. Since the charging terminal 15q is cut off from the outside by the door 15n, there is no fear of milking even when the drones 15 fly in the rain.

In any case, referring to FIG. 3A, the drones 15 are entering in the direction of the arrow z. The movement of these drones can be either wirelessly controlled by the operator or can be implemented by mutually responsive signals.

3B, the charging terminal case 15m pushes the pivotable door 13c in the direction of the arrow a and re-engages the electric power (not shown) And approaches the supply terminal 13f side.

3C, it can be seen that as the charging terminal case 15m further moves toward the power supply terminal 13f, the connection guider 13g pushes the door 15n in the direction of arrow b . The door 15n is opened by the reaction force of the movement of the drones 15.

3D, when the charging terminal case 15m is completely inserted into the internal space 13e, the power supply terminal 13f and the charging terminal 15q are connected to form the connecting body 13k . And the charging electric power is supplied to the battery 16h inside the drone.

In this charging mode, when the drones 15 are separated from the drones 13, the pivotable doors 13c and doors 15n are automatically closed by the action of the elastic hinges 13d and 15p.

5 is a flowchart illustrating an example of an intelligent video surveillance method according to an embodiment of the present invention.

5, the intelligent video surveillance method according to the present embodiment includes a droning waiting step 100, a droning dispatching step 102, a mission performing step 110, a returning step 112, And a charging step 114.

The droning step 100 is a process of waiting the drones 15 in a charged state to the drones 13. In this case, the photographing unit 15f operates and photographs the surroundings in real time. It is like a fixed CCTV. The drones 15 waiting through the drones waiting step 100 are ready to be dispatched at any time.

For example, if an operator receives a dispatch signal or if an emergency situation occurs, the dispatcher autonomously dispatches the dispatcher to the situation occurrence area.

The drones dispatch step 102 is a process of moving to a situation occurrence area when an emergency situation occurs. At this time, maneuver refers to maneuver for flight. It is natural that the charging terminal 15q is disconnected from the power supply terminal 13f when the drones are dispatched. Further, the alarm output unit 16c is operated while the drones are dispatched to warn nearby people that the emergency situation is occurring.

The subsequent mission execution step 110 is a process of causing the drones 15 arriving at a situation occurrence area to photograph an object related to the situation and transmit the photographed contents to the operator through a wireless communication method. Also, if the type of the generated situation is a crime, the process of finding and tracking the escape person through the analysis unit 16e is also included. The police can arrest the escapee more quickly based on the images sent by the drones (15).

After completing the various tasks described above, a return step 112 is followed. The returning step 112 is a process of guiding the drones 15 that have completed the mission to the nearby drones station 13. In this way, the drones 15 return to the closest drones 13 without having to return to the drones 13 from which they originated. The reason for this is that, when returning to the starting drone station 13, the battery may be discharged in the middle.

The drone 15 returned to the empty drone station 13 in the vicinity is connected to the power supply terminal 13f through the process shown in FIG. 3A to FIG. 3D and carries out the charging step 114. FIG. That is, power is supplied through the power supply terminal 13f. The photographing unit 15f and the communication unit 16k can be continuously operated while power is supplied.

6 is a flowchart illustrating another example of an intelligent video surveillance method according to an embodiment of the present invention.

The same reference numerals as those of the above-mentioned reference numerals indicate the same members having the same function.

The video surveillance method shown in Fig. 6 is a method of dispatching the waiting drones 15 at a set patrol time, instead of dispatching them when an emergency situation occurs.

This video surveillance method includes a droning waiting step 100, a droning patrolling step 120, a mission performing step 110, a returning step 112, and a filling step 114.

The drone patrol step 120 activates the drone 15 at the input patrol time so that the drone is allowed to fly along the determined patrol route. The patrol route of the drones depends on the GPS coordinate line, the beacon line or the Wifi line.

In the course of the drone patrol step 120, when an emergency situation occurs, a mission performing step 110 is performed. However, if an emergency situation does not occur, the drone returns to the drone station 13 from which he has started and carries out the charging 114 step.

The mission performing step 110, the returning step 112 and the charging step 114 following the occurrence of an emergency situation are the same as those described with reference to FIG. 5, and a description thereof will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
