In step 431, the transmission / reception control unit 310 may receive the key information generated and encrypted by the server 150 from the server 150 for authentication of the user terminal 110. For example, the key information may represent key information generated and encrypted based on the unique information of the UAV 160, unique information of the user terminal 110 (e.g., a unique user identifier (UUID) Mobile phone number, etc.) of the mobile terminal.

In step 432, the transmission / reception control unit 310 may receive the encrypted key information broadcasted from the user terminal 110. [ Here, the encrypted key information may be generated based on the unique information of the UAV 160 as key information generated and encrypted in the server 150, or may be generated based on the unique information of the user terminal 110, Key information.

For example, the transmission / reception control unit 310 may set the corresponding wireless interface to a listening state for communication with the user terminal 110 at a destination based on the wireless interface of the user terminal 110 determined by the server 150 have. When it is set to the listen state, the transmission / reception control unit 310 can receive the encrypted key information broadcasting from the user terminal 110. [ For example, when the Bluetooth communication interface is determined by the wireless interface used for communication with the user terminal 110 in the server 150, the Bluetooth communication interface is set to the listen state, and the transmission / reception control unit 310 uses the Bluetooth communication The WiFi interface or the LTE interface is set to the listen state when the wireless interface determined by the server 150 is WiFi or LTE, Encrypted key information may be received from the user terminal 110.

In operation 433, the authentication unit 320 may authenticate the user terminal 110 based on the encrypted key information received from the user terminal 110 and the encrypted key information received from the server 150. For example, the authentication unit 320 may decrypt the encrypted key information of the user terminal 110 and decrypt the encrypted key information of the server 150. [ The authentication unit 320 can authenticate the user terminal 110 by comparing whether the key information of the decrypted user terminal 110 and the key information of the server 150 match.

If the authentication of the user terminal 110 is successful in step 440, the landing control unit 330 may communicate with the user terminal 110 to determine a landing point.

For example, the landing control unit 330 may determine a point at which the UAV 160 can land and land based on the GPS coordinate information corresponding to the destination as a landing point. For example, a playground or an empty spot in a house, a garden, a rooftop, or an apartment complex corresponding to the GPS coordinates or around a point corresponding to the GPS coordinates may be determined as a landing point.

As another example, when the user terminal 110 is successfully authenticated, the landing control unit 330 receives the GPS coordinates corresponding to the landing point directly selected by the user on the map displayed on the screen of the user terminal 110 from the user terminal 110 And can determine a point corresponding to the received GPS coordinate information as a landing point. That is, the user can select one of the possible landing positions on the map and induce landing at the corresponding position. Thus, by selecting the landing point directly on the map, the user can prevent the unmanned aerial vehicle from landing on the private land or space where access is difficult, such as the adjacent roof of the building or the neighboring yard. At this time, the map displayed on the user terminal may represent a map including information of nearby facilities based on GPS coordinate information corresponding to the shipping address information inputted at the time of delivery.

In step 450, the landing control unit 330 may determine whether or not the landing may be attempted before landing at the determined landing point by communicating with the user terminal 110. [

At this time, the landing control unit 330 calculates the distance between the user terminal 110 and the UAV 160 based on the signal strength of the corresponding wireless interface, based on the wireless interface of the user terminal 110 determined by the server 150 . Then, the landing control unit 330 can determine whether or not the landing attempt is made based on the calculated distance.

For example, if the wireless interface of the user terminal 110 determined at the server 150 is WiFi, it may transmit 802.11 frames by radiating RF energy at a given signal strength, referred to as EIRP (Equivalent Isotropically Radiated Power). As the RF energy is radiated from the antenna of the transmitter, the wavefront can travel through the air and obstacles in the direction of propagation. Free Space Path Loss represents the power lost when energy is scattered into the air, as shown in Table 1 below, and can be expressed as a function of frequency and distance.

According to Table 1, as the receiver is farther away, the power loss increases and the received signal strength indicator may be lowered due to power loss. The free space path loss is predictable and can be calculated from the formula in Table 1 above. Before the landing of the unmanned aerial vehicle (drone), the landing control unit 330 controls the space in which the unmanned aerial vehicle can be delivered, that is, The distance between the unmanned aerial vehicle and the user terminal 110 can be measured by the signal strength. At this time, since the actual signal strength for each type of major user terminal is registered and managed in advance, the distance can be calculated more precisely based on the intensity of the signal output from the user terminal 110. [

The landing control unit 330 measures a signal strength received from the user terminal 110 and calculates a distance to the user terminal based on the measured signal strength. At this time, the distance between the terminal to receive the goods and the unmanned aerial vehicle is not calculated based on the signal strength of the user terminal 110 to be received, but the landing control unit 330 may calculate a plurality of The distances to the user terminals can be calculated based on the intensity of the signal corresponding to each of the user terminals.

In step 451, the landing control unit 330 may activate a plurality of sensors included in the sensor module to determine whether the access object to the UAV 160 is a user terminal 110 to receive a product. At this time, the landing control unit 330 may determine whether the access object is the user terminal 110 based on the signal of the wireless interface of the detected access object. It can be determined whether or not the access object is the user terminal 110 based on the signal for each individual wireless interface.

For example, the type of the wireless interface supported by the user terminal 110 may be registered in the server 150 and may be managed by matching with the identifier information of the user terminal 110. Information indicating the type of the wireless interface supported by the user terminal 110 may be previously provided from the server 150 before the unmanned air navigation apparatus starts to deliver the goods, and may be stored in the unmanned aerial vehicle. If there is more than one wireless interface detected in the vicinity of the unmanned aerial vehicle, the landing control unit 330 receives signal information indicating an air interface supported by the user terminal 110 to receive the registered goods from the server 150, Based on the signal information of the mutually set wireless interfaces, it is possible to determine whether the access object is the user terminal 110 to receive the goods or an anonymous object. For example, when the signal information of the wireless interface of the goods receipt terminal designated by the server 150 is WiFi, if the signal information of the wireless interface received from the access object is signal information indicating WiFi, And it is determined that the access object is an anonymous object other than the user terminal 110 in the case of non-WiFi signal information (e.g., visible light, Bluetooth, etc.). At this time, the signal information of the air interface of the user terminal 110 may be received in the form of an encrypted message in the format specified by the server 150 side.

In step 452, as the access object is determined to be the user terminal 110, the landing control unit 330 can control the flight so that the UAV 160 landing at the landing point. At this time, the surrounding environment of the UAV 160 can be photographed after the landing spot of the UAV 160 is determined, through a camera activated immediately before landing, during landing, or after landing. Then, the transmission / reception control unit 310 can transmit the photographed images (e.g., moving images, still images, etc.) to the server 150 in real time.

At this time, if it is determined that the access object is not the user terminal 110, that is, the user is another anonymous user, an animal, etc., the landing control unit 330 can control the access warning function to be driven. The avoidance function for protecting the goods and the UAV 160 from an anonymous object when the access object is not the user terminal 110 will be described later with reference to FIG.

In step 460, the receipt confirming unit 340 releases the loading of the merchandise mounted on the UAV 160 according to the landing at the landing point, and delivers the merchandise to the user.

In step 470, the receipt confirmation unit 340 may request the server 150 to confirm whether the goods are normally delivered to the user who ordered the goods.

At this time, if it is confirmed that the product is normally delivered to the user at the server 150 and the return command is transmitted, the transmission / reception control unit 310 returns to the return location based on the designated return route in accordance with the return command received from the server 150 can do. For example, the return route information may be provided together from the server 150 while receiving the return command, or may be provided from the server 150 at the departure.

If it is determined in step 430 that the user terminal 110 is not located in the vicinity of the destination, the UAV 160 waits in the destination according to the command of the server 150 or returns to the destination . Similarly, when the authentication of the user terminal 110 fails, the UAV 160 informs the server 150 of the authentication failure, and waits for the destination according to the command of the server 150, You can either re-authenticate or return to the ship's departure location.

For example, if the user terminal 110 is not found to be located around the destination within the predetermined reference time, or if the battery level of the UAV 160 corresponds to the level set as the return request, the server 150 The unmanned aerial vehicle 160 may send a return command to the unmanned aerial vehicle 160, and the unmanned airborne device 160 may fly back to the departed location for delivering the goods. Until the reference time is reached or until the remaining battery level becomes the level set for the return request, the UAV 160 transmits the air data corresponding to the GPS coordinates information of the destination according to the command of the server 150 ). ≪ / RTI >

5 is a flowchart illustrating an operation of an access warning function when an object accessing the UAV is not a user terminal in an embodiment of the present invention.

5, it is assumed that the access object is not the user terminal 110 after the unmanned air navigation device 160 lands at the landing point, and the access warning function is driven. However, before the landing, The warning function may be activated. The steps 510 to 540 of FIG. 5 may be performed by the landing control unit 330.

In step 510, the landing control unit 330 can control the flight so that the UAV 160 lands at the landing point.

In step 520, the landing control unit 330 activates a plurality of sensors mounted on the UAV 160 so as to determine whether there is an object approaching within a certain predetermined radius from the UAV 160 Can be detected.

For example, the landing control unit 330 can detect whether an object approaching within a certain radius exists by using an infrared sensor, a proximity sensor, or the like.

In step 530, when the access object is detected, the landing control unit 330 can check whether the detected access object is the user terminal 110 to receive the goods.

At this time, the landing control unit 330 can determine whether it is the wireless interface of the registered user terminal 110 determined by the server 150 based on the wireless interface of the access object. For example, it can be determined whether the access object is the user terminal 110 based on the signal strength of the individual air interface.

If it is determined in step 540 that the access object is not the user terminal 110 to receive the goods, the landing control section 330 may drive the approach warning function.

In step 541, the landing control unit 330 drives a warning light, a warning sound, a propeller rotation, and the like using a sensor mounted on the UAV 160 to warn the approaching object not to approach the UAV 160 have.

For example, the LED sensor may be blinking, a warning sound such as 'beep-beep' may be output through the speaker, and the propeller of the unmanned aerial vehicle 160 may be rotated while landing at the landing point. At this time, the propeller can be prepared to be able to take off immediately when it is intended to approach the unmanned aerial vehicle 160 secondarily while preventing the approach object from rotating by turning.

If the access object is located closer to the unmanned aerial vehicle than the predetermined radius and within the predetermined reference radius in step 542, the landing control unit 330 controls the unmanned aerial vehicle 160 to fly up to the predetermined safe altitude Can be controlled. At this time, the safe altitude may include a plurality of levels, and the altitude may be elevated step by step. For example, at the time of the first ascension, the object can fly vertically up to an altitude of level 1 set to a height not reachable by an access object (an anonymous person or animal). In this case, when the access to the UAV 160 is continuously detected even at the altitude raised to the level 1, the landing control unit 330 may further fly up to the altitude of level 2 set higher than the level 1. For example, the access to the unmanned aerial vehicle 160 may be attempted using a bar, a dragonfly, or the like, so that even if a physical object is used, (160) can fly up. In addition to level 1 and level 2, there may be more levels of higher level 3, level 4, and so on.

 As described above, the landing control unit 330 can continuously monitor whether or not the access object approaches the reference radius, which is the nearest region, by using the proximity sensor and the infrared sensor even after the approach object approaches a certain radius. At this time, as the peripheral image of the UAV 160 is photographed and transmitted to the server 150 in real time using the camera from the time of landing, damage or theft of the UAV 160 is all photographed and monitored . The captured image information can be used as a basis for analyzing the problem of the future delivery process using the unmanned aerial vehicle and for the occurrence of an anomaly.

The landing control unit 330 may request the server 150 to communicate with the user terminal 110 when the unmanned aerial vehicle 160 has risen from the landing point due to an anonymous access object.

If communication is permitted in the server 150 in step 544, the landing control unit 330 may request the user terminal 110 to judge whether or not the landing position is re-landed. That is, if an anonymous object is detected at the landing point, the user having the user terminal 110 can determine whether or not it is safe to re-land at the landing point.

For example, the landing control unit 330 may transmit a message to the user terminal 110 through the wireless interface of the user terminal 110 to inform the user that the movement of the anonymous object has been detected at the landing point. Here, a re-landing permission message such as 'an anonymous object (such as a person or an animal) is approaching the delivery commodity', 'please confirm if it is safe to land at the landing point', or the like is transmitted to the user terminal 110 And the re-landing permission message may be registered in advance from the server 150 before the unmanned aerial vehicle 160 starts delivering the goods.

At this time, the re-landing permission message may include display information (icons, buttons, etc.) for the user to select permission or denial. If permission is selected, the landing control unit 330 determines that the unmanned aerial vehicle 160 is at the landing point Lt; / RTI > If not selected, the UAV 160 may continue to fly and wait at the safe altitude.

For example, the re-landing permission and denial process from the user terminal 110 may be performed through direct communication between the UAV 160 and the user terminal 110, as described above, and may be performed via the server 150 . The server 150 may transmit a re-landing permission message to the user terminal 110. If the user terminal 110 is allowed to re-land the vehicle, the re-landing permission command may be transmitted to the UAV 160 If not, a wait command may be sent to the UAV 160.

If it is determined in step 544 that the communication is permitted in the server 150 and the user terminal 110 determines whether or not the user wants to re-land the vehicle, if the user terminal 110 does not receive a re- The control unit 330 can determine whether to wait or return based on the remaining battery power. For example, it is possible to determine that the battery remaining amount returns to a predetermined reference remaining amount required for return or a value close to a margin with respect to the reference remaining amount, and can return. If the battery remaining amount is sufficient, that is, if the battery remaining amount is equal to or larger than the margin of the reference remaining amount, the UAV 160 may wait on the air.

FIG. 6 is a block diagram illustrating an internal configuration of a server 150 for delivering goods to a user terminal using an unmanned aerial vehicle according to an exemplary embodiment of the present invention. , And FIG. 7 is a flowchart illustrating an example of a method that a server according to an embodiment of the present invention can perform.

6, the processor 222 included in the server 150 includes a transmission / reception control unit 610, a user terminal confirmation unit 620, a key information generation unit 630, and an acknowledgment unit 640 ). The components of the processor 222 and the processor 222 may control the server 150 to perform the steps 710 to 750 included in the method of determining the destination in the server of FIG.

First, the server 150 may perform a basic setting for authenticating the user terminal 110 at a destination and delivering the goods safely, in order that the unmanned aerial vehicle 160 designated for delivering the goods to the user terminal 110 . For example, the navigation path, the destination information, the air interface information of the user terminal 110, and the like may be transmitted to the UAV 160 or may be registered and set. At this time, in order to provide the wireless interface information of the user terminal 110 to the UAV 160, the transmission / reception control unit 610 may request the available wireless interface information available from the user terminal 110 to the user terminal 110 have. At this time, the available wireless interface may be registered in advance when the product is ordered, or may not be registered, and the transmission / reception control unit 610 may transmit the link information for registering the available wireless interface to the user terminal 110 to register. The wireless interface may include WiFi, LTE, Bluetooth, visible light, and the like. The available air interface registered from the user terminal 110 may be stored in the memory 221 by matching with the identification information of the user terminal 110 according to the user's agreement.

When there is a plurality of available wireless interfaces of the user terminal, the server 150 transmits the available air interface to the user terminal (e.g., the air interface 160) 110 and the unmanned aerial vehicle 160 can be determined.

In step 710, the transmission / reception control unit 610 determines a wireless interface to be used for communication between the user terminal and the UAV, on the available wireless interface of the user terminal to receive the goods, and transmits the determined wireless interface to the UAV 160 ) And register it. At this time, the normal operation of the wireless interface of the user terminal registered in the UAV 160 before the delivery of the goods can be checked.

The server 150 may transmit the air interface information for communication with the user terminal 110 registered in the UAV 160 to the user terminal 110 and register the air interface information. For example, when a delivery service using an unmanned aerial vehicle is performed based on an application installed in the user terminal 110, the wireless interface may be registered with a wireless interface to be used in communication with the UAV 160 through the application have. The server 150 may request the UAV 160 to obtain access and use rights to the registered air interface and when the access right and the use right are authorized by the user terminal 110, And instructs the aviation apparatus 160 to start delivery of goods.

In step 720, when the unmanned aerial vehicle 160 approaches the vicinity of the destination through the delivery route, the transmission / reception control unit 610 confirms whether the user terminal 110 is present around the destination from the unmanned air navigation device 160 Can be requested.

At this time, the transmission / reception control unit 610 can notify the user terminal 110 of the start of delivery when the unmanned aerial vehicle 160 starts to be delivered. The transmission / reception control unit 610 periodically receives and monitors the current location information of the UAV 160 from the UAV 160 from the time when the UAV 160 starts to deliver, The current location information of the user terminal 110 can be received and monitored.

In step 730, the user terminal identification unit 620 identifies the user terminal 110 based on the current location information (i.e., the GPS coordinate information) of the user terminal 110 and the location information (i.e., GPS coordinate information) It can be confirmed whether or not it is located around this destination. For example, it can be determined whether the user terminal 110 exists within a range where the UAV 160 can communicate wirelessly with the user terminal 110 based on the destination. It is possible to confirm whether or not the registered user terminal exists within a distance that can be communicated with the registered wireless interface around the destination because the range of communication is different according to the type of the wireless interface of the registered user terminal and the communication range is known in advance. Then, the transmission / reception control unit 610 can transmit the confirmation result to the UAV 160.

The key information generator 630 can generate key information for authentication between the user terminal 110 and the UAV 160 according to the confirmation that the user terminal 110 is located in the vicinity of the destination in step 740 have. At this time, the key information generation unit 630 may generate either one of the key information using the unique information of the UAV 160 and the key information using the unique information of the user terminal 110, have. Then, the generated one or two pieces of key information can be transmitted to the user terminal 110 and the UAV 160.

As the unmanned aerial vehicle 160 is successfully authenticated between the UAV 160 and the user terminal 110 using the key information, the UAV 160 is landed at the landing point and the product is delivered to the user . Then, the UAV 160 may request the server 150 to confirm whether or not the goods have been normally received.

In step 750, the receipt confirmation unit 640 can confirm receipt of the goods delivered by the UAV 160 to the user.

For example, the receipt confirmation unit 640 may transmit a message to the user terminal 110 including link information for receipt confirmation. At this time, as the link information of the message is selected in the user terminal 110, a web page for receiving information for confirming receipt can be displayed on the screen of the user terminal 110. [ Then, the receipt confirmation unit 640 receives the receipt confirmation information such as the barcode information of the goods delivered from the user terminal 110, the delivery number information, the ID of the UAV 160, and the like. The identification information of the product, the delivery information (that is, the bar code and the delivery number information), the identification information of the user terminal 110, and the identification information of the UAV 160 to which the goods are to be delivered are matched and stored in the memory 221, The receipt confirmation unit 640 may compare the receipt confirmation information input through the user terminal 110 with the information stored in the memory 221 to confirm whether the receipt of the normal receipt is successful.

If it is confirmed that the normal receipt has been performed, the transmission / reception control unit 610 can transmit a return command together with an indicator informing the unmanned aeronautic vehicle 160 that it has been normally received.

As described above, in the delivery system using the unmanned aerial vehicle, the server confirms whether there is a user terminal to receive a product around the destination, and the authentication of the user terminal is performed through direct communication between the unmanned aerial vehicle and the user terminal. And after confirming once again whether the object accessed by the unmanned aerial vehicle is a user terminal, the product is delivered to the user terminal, thereby delivering the product to the user who should receive the product more safely.
