Hereinafter, a user safety security function performed by the streamlined drone system according to an embodiment of the present invention will be described.

12 is a reference diagram for explaining the concept of a user safety security function performed by a streamlined drone system according to an embodiment of the present invention.

As shown, the user safety securing function performed by the streamlined drone system according to an embodiment of the present invention is that the drone 200 having a facial recognition function tracks the user P1 and takes close-up photographs, and then approaches within the set range. Then, by performing facial recognition on the other person (P2) whose distance (L) from the user (P1) is narrowed, it determines whether it is a dangerous person who may harm the user (P1), and alerts the guardian to the smart device based on the determination. It enables rapid response such as occurrence, output of an alarm sound around the user, and reporting to the police agency through communication. Through this, the user (P1) located at a distance from the guardian can be safely protected from the risk of crime.

Hereinafter, the user safety security function will be described in more detail.

13 is a flow chart illustrating a user safety security function performed by a streamlined drone system according to an embodiment of the present invention, and FIG. 14 is a flowchart illustrating a user safety security function performed by a streamlined drone system according to an embodiment of the present invention. 15A and 15B are a series of reference diagrams viewed from the side to explain the movement of the drone for smooth facial recognition in the user safety security function performed by the streamlined drone system according to an embodiment of the present invention, 16A to 16C are a series of reference diagrams viewed from above in order to explain the movement of the drone for smooth facial recognition in the user safety securing function performed by the streamlined drone system according to an embodiment of the present invention.

As shown in FIG. 13, the user safety securing function performed by the streamlined drone system according to an embodiment of the present invention includes storing the facial structure data of the user P1 (S11), and storing the facial structure data of acquaintances. Step (S12), the step of storing the facial structure data of criminals disclosed by the National Police Agency (S13), the step of tracking the user (P1) and taking a close-up photo (S14), the step of performing facial recognition of the other person (P2) (S15) , Generating an alarm (S16), and reporting to the National Police Agency (S17). Below, each step will be described in detail.

First, in the step S11 of storing the facial structure data of the user P1, the facial structure data of the user P1 is stored in the memory 160 mounted in the power box 100. Here, in order to generate the facial structure data of the user P1, facial structure data is generated from the image created by the photographing camera 230 for capturing the face of the user P1, and a plurality of facial structure data is compared and analyzed. As a result, facial recognition software that determines whether the person is the same person is required. Since such facial recognition software is installed in the power box 100, the processor 140 may generate the facial structure data of the user P1 and directly store it in the memory 160, or the user P1 may recognize facial recognition in the smart device. It is also possible to install software to generate the facial structure data of the user P1. In this way, when the facial structure data is generated by smart devices, it is transmitted to the power box 100 and stored in the memory 160.

In the storing of the acquaintance's facial structure data (S12), the facial structure data of the acquaintances determined by the user P1 is stored in the memory 160 mounted in the power box 100.

In the step S13 of storing the facial rescue data of the criminals disclosed by the National Police Agency, facial rescue data is generated from photographs or images of the criminals disclosed by the National Police Agency and stored in the memory 250 mounted on the drone 200. In the case of storing the facial structure data of criminals disclosed by the National Police Agency, unlike the previous case of storing the facial structure data of the user (P1) or acquaintance, it is not the amount of work that can be done by an individual. Alternatively, it is preferable to receive the criminal's facial structure data from the company and store it in the memory 160 of the power box 100.

In the step S14 of tracking and taking a close-up picture of the user P1, the drone 200 tracks the user P1 and takes a close-up picture of the user P1 and its vicinity. At this time, the drone 200 tracking the user P1 is equipped with a second communication module 250 in charge of communication with the outside in addition to the camera 230 for shooting, as described above, and from the battery 120 of the power box. Receive power. In addition, the drone 200 is equipped with an ultrasonic sensor 240 so that it is possible to quickly detect and avoid obstacles that have a risk of collision during driving such as birds and other drones appearing near the drone 200.

In order for the drone 200 to stably and effectively take close-up pictures of the user P1 and its vicinity, the most important thing is to secure the accuracy of the distance when the drone 200 tracks the user P1. In the present invention, a detailed method is provided that can secure distance accuracy while being inexpensive. This will be described in detail later.

In the step S15 of performing the facial recognition of the other person P2, when the other person P2 approaches the user P1 within the set range, facial recognition is performed on the approaching other person P2. To this end, the camera 230 mounted on the drone 200 photographs the face of another person P2 to create an image, and the processor 140 of the power box 100 drives the facial recognition software to create a facial structure from the image. Generate data. Subsequently, the generated facial structure data of the other person P2 is compared and analyzed with the facial structure data of the acquaintance and criminal stored in the memory 160 to determine whether the person is a registered acquaintance or a criminal.

As a method for smoothly performing facial recognition for the other person (P2) in the step S15, when the other person (P2) approaches the setting range (D3) as shown in Fig. 16a, the approaching other person ( The drone 200 is moved across the path of P2), and the camera 230 or the drone 200 is rotated so that the camera for shooting 230 faces the face of another person P2 approaching the user P1. give. At this time, if the photographing angle of the camera 230 with respect to the face of the other person P2 is not secured, the drone 200 is retracted from the other person P2 as shown in FIG. 16C to secure the photographing angle. The process of securing the photographing angle of the camera 230 shown in FIGS. 16B and 16C is viewed from the side of the user P1 rather than from the upper side, as shown in FIGS. 15A and 15B. As such, if the drone 200 actively moves with respect to the other person P2 approaching the user P1, it is possible to perform fast and accurate shooting and facial recognition as soon as the other person P2 enters the set range.

At this time, as can be seen in FIGS. 16A, 16B, and 16C, the camera 230 mounted on the drone 200 is an example of another person P2 approaching the user P1 even in a state where the position of the drone 200 is actively changed. They are preparing to send out photos or videos while continuing to take pictures.

In the step of generating the alarm (S16), if it is determined that the other person (P2) approaching within the set range through the previous step does not match the facial structure data of the acquaintances previously stored in the memory 160, the drone 200 2 The photo or video is transmitted to the guardian's smart device through the communication module 250 and an alarm is issued. As such, the alarm emitted from the guardian's smart device is provided in the form of an alarm sound through the smart device, screen output, etc. Then, the guardian can identify whether the safety of the user (P1) is in a dangerous situation by checking the alarm emitted by the smart device and looking at photos, videos, and location information provided through the smart device. In such cases, immediate measures can be taken, such as reporting to the National Police Agency.

When performing step S16 above, as shown in FIG. 14, the setting range centered on the user P1 is divided into a first area D1 having a relatively small radius and a second area D2 having a relatively large radius. If classified, a more detailed step-by-step response becomes possible. That is, if the other person (P2) approaching within the set range is not a criminal, but is not an acquaintance, when approaching the second area (D2), an alarm is issued through the guardian's smart device, while the user's smart device or a speaker installed in the power box 100 By outputting an alarm sound through, the approaching other person (P2) recognizes that the user (P1) is being monitored by the drone (200). However, if the other person (P2) does not give up access to the user (P1), but further approaches and enters the first area (D1), the risk level is further elevated and the user's smart device or the speaker installed in the power box 100 At the same time, it outputs a loud alarm sound and promptly reports to the police so that a stronger response can be made.

In the step of reporting to the National Police Agency (S17), when it is determined that the facial structure data of the other person P2 who has approached the user P1 within the set range matches the facial structure data of the criminals previously stored in the memory 160, the second Not only the alarm is issued to the guardian's smart device through the communication module 250, but at the same time, it is automatically reported to the police office. Accordingly, it is possible to respond most strongly to criminals who may threaten the safety of the user P1.

Even when performing step S17 above, as shown in FIG. 14, the setting range centered on the user P1 is changed to a first area D1 with a relatively small radius and a second area D2 with a relatively large radius. If it is divided, a more detailed step-by-step response can be made. That is, if another person (P2) approaching within the set range is judged to be a criminal, the highest risk level can be taken immediately, but when approaching the second area (D2), an alarm is issued through the guardian's smart device, while the power box ( 100) Or, through a speaker mounted on the user's smart device, an alarm sound is output to enable people to recognize that the approaching person (P2) is being monitored, and the other person (P2) approaches the user (P1) more If you enter the area 1 (D1), you can raise the level of danger further, output a loud alarm sound through the speaker, and immediately report to the National Police Agency to respond more strongly.

On the other hand, if the other person (P2) approaching the user (P1) within the set range wears a mask or sunglasses and face recognition is difficult, it is regarded as a criminal, and an alarm is issued to the guardian's smart device through the second communication module (250). It is desirable to respond to criminals by reporting to.

Here, in the case of the above steps, it is preferable that the guardian is adjusted according to the mode set for the drone 200 through his or her smart device. For example, such a parental setting mode may consist of a tracking mode, an alarm mode, and a safety mode.

When the tracking mode is set, the drone 200 tracks the user P1 and transmits a picture or video to the guardian's smart device while taking close-up pictures.

When setting the alarm mode, in addition to the tracking mode, if another person (P2) who approaches the user (P1) within the set range is not an acquaintance or is a criminal, an alarm is issued to the guardian's smart device, and the other person (P2) is the user (P1). If the level of risk increases by continuing to approach the police, they will be reported to the National Police Agency.

When setting the safety mode, the user (P1) is primarily alerted by generating an alarm sound through the speaker of the user's smart device to all others (P2) approaching within the set range, and other people (P2) approaching within the set range When it gets closer to the user P1, a report is made to the police agency through the first communication module 150. By providing various parental setting modes as described above, it becomes possible to protect the user P1 while showing flexibility according to the situation.

In the following, a detailed method for securing the accuracy of the distance, which can be said to be most important when the drone 200 tracks the user P1, will be described.

17 is a flowchart illustrating a method of tracking a user of a drone in a user safety security function using a streamlined drone system according to an embodiment of the present invention.

As shown in FIG. 17, in an embodiment of the present invention, in order to track the user P1, the user's smart device and the drone are absolute by using the GPS of the user's smart device possessed by the user P1 and the GPS of the drone. Measuring coordinates (S10), measuring the distance between the user's smart device and the drone and the height of the drone using the signal strength between the user's smart device and the drone's Bluetooth (S22), the drone is the user Storing the distance between the smart device and the drone as a reference value (S23), and when a change in the reference value (S) occurs, moving the drone to maintain the distance between the user's smart device and the drone as a reference value (S) (S24) is included, and in order to implement such a user (P1) tracking method, the drone 200 is provided with a second communication module capable of communicating with GPS and Bluetooth.

First, a step (S21) of measuring the absolute coordinates of the user's smart device 100 and the drone 200 using the GPS of the user's smart device 100 and the GPS of the drone 200 is performed. For example, when the user smart device 100 is interlocked with the drone 200 to be tracked, the user smart device 100 measures the absolute coordinates of the X and Y axes using GPS from the first communication module 150). , The drone 200 measures the absolute coordinates of the X and Y axes using GPS from the second communication module 250.

After step S21, measuring the distance between the user's smart device 100 and the drone 200 and the altitude of the drone 200 using the signal strength between the Bluetooth of the user's smart device 100 and the Bluetooth of the drone 200 ( S22) is performed.

When the Bluetooth of the user's smart device 100 and the Bluetooth of the drone 200 are paired, signal strength is generated with each other, and the distance between the user's smart device 100 and the drone 200 is measured using this. In addition, since the absolute coordinates of the user's smart device 100 and the drone 200 have already been measured by the step S21, the absolute coordinates and the linear distance between the user's smart device 100 and the drone 200 are used to determine the drone 200. ) The altitude can be measured. Specifically, when a master bluetooth module is provided in the user's smart device 100, a slave bluetooth module is provided in the drone 200, and when the master bluetooth module and the slave bluetooth module are paired, each other Signal strength occurs as Bluetooth communication is established.

The signal strength is preferably programmed using an RSSI (Received Signal Strength Indication) value in order to secure distance accuracy between two Bluetooth modules. The distance between the user's smart device 100 and the drone 200 is measured using the programmed RSSI value, and the altitude of the drone 200 is measured from the absolute coordinate value of the GPS.

After the step S22, the drone 200 performs a step (S23) of storing the distance between the user's smart device 100 and the drone 200 as a reference value (S). Specifically, the memory 160 of the drone 200 stores the distance between the user's smart device 100 and the drone 200 as a reference value (S), and the first communication module 150) and the second communication module 250 Through the transmission and reception of information between the drones, the drone is programmed to maintain the reference value (S).

When a change in the reference value S occurs after the step S23, the drone 200 moves to maintain the distance between the user's smart device 100 and the drone 200 as the reference value S (S24). The drone 200 can continuously track the user P1 having the user smart device 100 at a certain distance.

In the step S24, when the user smart device 100 moves, the user smart device 100 transmits the acceleration and angular velocity values of the user smart device 100 to the drone 200, and the drone 200 transmits the transmitted acceleration and It can be programmed in such a way that the distance between the user smart device 100 and the drone 200 is maintained as the reference value S by calculating the position and speed values of the user smart device 100 from the angular velocity value. In this case, the user smart device 100 should further include an acceleration sensor and a gyro sensor. That is, when the user's smart device 100 is configured to further include an acceleration sensor and a gyro sensor, the processor of the power box uses GPS and Bluetooth, along with information on absolute coordinates and relative distances, of the user's smart device 100. Since acceleration and angular velocity information can also be used to accurately calculate the position and velocity values of the user's smart device 100, the accuracy of maintaining the reference value S can be remarkably improved.

In addition, the step S24 calculates the movement speed of the user smart device 100 from the movement distance of the user smart device 100 during the signal waiting time of the drone 200 when the user smart device 100 moves. The drone 200 may be configured to move so that the distance between 100) and the drone 200 can be maintained at the reference value S. In this case, the signal waiting time of the drone 200 is the time when the user's smart device 100 moves to an arbitrary location instantaneously and the time when the user's smart device 100 moves to an arbitrary location and the drone 200 Refers to the time until the information moved to the location is received, and a reference value using information of the movement speed of the user smart device 100 calculated from the movement distance of the user smart device 100 during the signal waiting time (S) The accuracy of maintenance can be improved.

Here, in order to improve the stability of user P1 tracking, a supplementary device when communication information is not transmitted smoothly may be further added. For example, when the second communication module 250 of the drone 200 fails to receive communication information of GPS and Bluetooth from the user's smart device 100, the drone 200 is at a position at a point in which communication information is not received. It may be configured to further include a step (S25) of attempting an emergency landing. In addition, when the drone 200 includes an acceleration sensor and a gyro sensor, when the drone 200 does not receive any one of communication information of GPS or Bluetooth from the user's smart device 100, the drone 200 May further include a step (S26) of temporarily limiting the received information for maintaining the reference value (S) to information transmitted from the acceleration sensor and the gyro sensor.

Although the preferred embodiment of the present invention has been described above, the present invention can use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments.
