Description

{Speed gate comprising accessor location indicating-bar and access control method using the same}

The present invention relates to a speed gate including an entry/exit location indicator bar and an access control method using the same. Specifically, the present invention relates to a speed gate including an entry/exit location indicator bar which can support smooth passage of entry/exiters and efficient monitoring by managers by indicating the location of entry/exiters within a passage through the indicator bar, and an access control method using the same.

The material described in this section merely provides background information for the present embodiment and does not constitute prior art.

Speed gates are installed and operated in buildings or workplaces to allow only authorized persons to pass through and block unauthorized persons from entering. These speed gates implement a function that automatically opens the gate after authenticating the identity of the entrant by extracting the identity of the entrant through an authentication method such as a previously issued IC card or fingerprint through a reader.

In addition, in the case of radiation management facilities such as nuclear power plants, which are not general buildings, for the safety of entrants and the facility, entrants wear dosimeters, and the dosimeters of entrants are recognized at the speed gate to check the radiation exposure of workers and confirm the validity of work permits, thereby simultaneously performing confirmation of the level of radiation exposure of entrants and access control management.

On the other hand, if a person entering the speed gate after completing authentication fails to complete passage within a certain time, there may be a problem in which the authentication of the person entering is not accurately recorded. In addition, access control management for the speed gate can be further strengthened by having the manager monitor trends and routes through CCTV, but it is practically difficult for the manager to monitor the CCTV footage of the gate in real time, and there is also a limitation in that it is difficult to clearly identify whether a person has entered the passage, i.e., whether the speed gate is operating, using only the footage.

The purpose of the present invention is to provide a speed gate that supports an entrant who has completed authentication to pass through a passage within an appropriate time, and an access control method using the speed gate.

In addition, an object of the present invention is to provide a speed gate and an access control method using the same, which enable a manager to easily identify whether a person has entered a passageway and the location of the person in the passageway.

In addition, an object of the present invention is to provide a speed gate and an access control method using the same, which can help an administrator easily identify the direction of movement of an entrant with only a still image without monitoring all of the captured CCTV footage.

In addition, an object of the present invention is to provide a speed gate and an access control method using the same, which can reduce power consumption by applying a low-power system in which a lidar sensor is selectively activated only when an entrant is authenticated.

In addition, an object of the present invention is to provide a speed gate and an access control method using the same, which allows access of other objects (entrants) after the passage of a currently passing entrant has been completed, and blocks reverse passage of entrants entering a passage through an exit, thereby enabling stable access control management of entrants.

The purposes of the present invention are not limited to the purposes mentioned above, and other purposes and advantages of the present invention which are not mentioned can be understood by the following description, and will be more clearly understood by the embodiments of the present invention.

Hereinafter, speed gates according to some embodiments of the present invention will be described with reference to FIGS. 1 to 10.

FIG. 1 is a block diagram for explaining the configuration of a speed gate according to some embodiments of the present invention. FIG. 2 and FIG. 3 illustrate exemplary external shapes of a speed gate according to some embodiments of the present invention. FIG. 4 to FIG. 9 illustrate exemplary processes for a person passing through a speed gate according to some embodiments of the present invention. FIG. 10 illustrates exemplary indication of the direction of movement of a person using an indicator bar.

A speed gate (10) according to some embodiments of the present invention is arranged corresponding to a passage (20) to perform access control management for entrants entering and exiting the passage (20). In addition, the surrounding environment of the speed gate (10) can be captured in real time through CCTV, and the manager of the speed gate (10) can be in a state of monitoring the speed gate (10) through CCTV footage.

Referring to FIG. 1, the speed gate (10) includes a main body (100), a reader (110), a control unit (120), a display bar (130), a lidar sensor (140), an object recognition sensor (150), a speaker (160), a gate door (170), and a motor (180).

The main body (100) constitutes the outer shape of the speed gate (10), and can store the components of the speed gate (10) described above on the inside or so that they appear on the outside. Referring to FIGS. 2 and 3, it can be seen that the reader (110), the display bar (130), the lidar sensor (140), the object recognition sensor (150), the speaker (160), and the gate door (170) are stored on the outside of the main body (100) so that the components can be recognized from the outside. The main body (100) can have an outer shape that extends along the passage (20), and can be configured with a length corresponding to the passage (20). In addition, the main body (100) can be formed at a certain height to prevent an entrant from escaping through a path other than the direction of travel (from entrance to exit) of the passage (20).

The main body (100) includes a first main body (100A) and a second main body (100B) that are arranged to be spaced apart from each other with a passage (20) therebetween. The width of the passage (20) may be defined as the distance between the first main body (100A) and the second main body (100B), and the width of the passage (20) may be defined so that one person can move freely.

The gate door (170) can be stored at least partially in the main body (100). As illustrated in FIG. 2, when the gate door (170) is not stored in the main body (100) and blocks the passage (20), passage (20) can be blocked from passage by people entering or exiting. As illustrated in FIG. 3, when at least a portion of the gate door (170) is stored in the main body (100), passage (20) can be opened, allowing people to enter or exit.

The gate door (170) includes a first gate door (170A) accommodated in the first main body (100A) and a second gate door (170B) accommodated in the second main body (100B). The first gate door (170A) and the second gate door (170B) can be controlled to come closer to each other and be closed, and can be controlled to move away from each other and be opened. The positions of the first gate door (170A) and the second gate door (170B) can be changed in a sliding manner. A motor (180) can be included in each of the first main body (100A) and the second main body (100B) for sliding the gate door (180).

Here, a state in which the gate door (170) is closed to block passage through the passage (20) is defined as a standby state of the speed gate (10), and a state in which the gate door (170) is opened to allow passage through the passage (20) is defined as an activated state of the speed gate (10). The basic state of the speed gate (10) corresponds to a standby state, and a state transition to an activated state of the speed gate (10) can be determined according to identification information provided from a reader (110).

As illustrated in FIG. 4, an entrant can approach the entrance of a passage (20) according to the direction of movement. The reader (110) can read an authentication means of an entrant who has approached the entrance of the passage (20) to obtain identification information. Here, the authentication means of the entrant includes at least one of the entrant's biometric information, an authentication code issued in advance to the entrant, an authentication tag, and an authentication device. The reader (110) is configured to include at least one of a touch monitor, a fingerprint recognition device, a facial recognition device, a barcode reader, an NFC reader, and an RF reader. The touch monitor, the fingerprint recognition device, and the facial recognition device recognize biometric information (such as fingerprints, pupils, blood vessels, or face) of an entrant to obtain identification information. The barcode reader recognizes an authentication code, and the NFC reader and the RF reader recognize an authentication tag issued in advance to obtain identification information.

In this embodiment, the speed gate (10) is a gate for controlling the entry and exit of entrants into the radiation management area, and entrants may carry a dosimeter. The dosimeter refers to a device for measuring the amount of radiation received by the entrant. The dosimeter may include an electronic personal dosimeter (hereinafter referred to as EPD) and a thermo luminescent dosimeter (hereinafter referred to as TLD). Here, the EPD refers to a dosimeter that automatically inputs dose records into a computer and can be used for radiation exposure management when the electronic dosimeter is inserted into a designated storage rack in the radiation management area. The TLD refers to a dosimeter that emits light according to the amount of radiation received and can detect the radiation exposure based on the emitted light. An EPD or TLD is a personal dosimeter that must be worn in a radiation management area, and is used to measure the radiation exposure and accumulated dose of a worker. Additionally, in the embodiment, the entrant may include a work permit for the radiation management area leading to the exit of the speed gate (10). Only with a valid work permit can the entrant be permitted to enter the radiation management area.

The reader (110) is configured to include a rack in which EPDs can be stored, and can be configured to exchange data with the TLD. The reader (110) can exchange data with the dosimeter of the entrant to measure at least one of the radiation dose of the entrant and the accumulated dose of the entrant. In addition, the reader (110) can read the work permit of the entrant. That is, the identification information acquired by the reader (110) can include at least one of the radiation dose of the entrant and the accumulated dose of the entrant and the work permit.

The control unit (120) can control whether to open or close the passage (20) by adjusting the position of the gate door (170) based on the identification information acquired from the reader (110). The control unit (120) can determine whether the identification information is valid and, based on the validity, determine whether to open or close the passage (20). The validity of the identification information can be determined by whether the acquired identification information matches pre-stored information. If the pre-stored information and the identification information do not match, the identification information is determined to be invalid. In addition, if the identification information includes at least one of the radiation dose of the entrant and the cumulative dose of the entrant, the validity of the identification information can be determined by whether at least one of the radiation dose of the entrant and the cumulative dose of the entrant exceeds the allowable dose. If it exceeds the allowable dose, the identification information is determined to be invalid.

If the identification information is valid, the control unit (120) can control the gate door (170) to be opened as shown in Fig. 5 so that the speed gate (10) is activated. If the identification information is invalid, the control unit (120) closes the gate door (170) so that the speed gate (10) is maintained in a standby state. This change in the state of the speed gate (10) can be identified through a color change in the display bar (130).

The display bar (130) includes a plurality of light-emitting elements arranged along the extension direction of the main body (100). Each of the plurality of light-emitting elements may be configured to display a natural color. In an embodiment, the display bar (130) may be an LED bar including a plurality of LED light-emitting elements. Each of the LED light-emitting elements is configured to include a red LED (R), a green LED (G), and a blue LED (B) to display a plurality of colors based on signals applied to R, G, and B. However, the present invention is not limited thereto, and the display bar (130) may be an OLED bar including a plurality of OLED light-emitting elements, and each of the OLED light-emitting elements is configured to include a red OLED (R), a green OLED (G), and a blue OLED (B) to display a plurality of colors based on signals applied to R, G, and B.

The color displayed on the display bar (130) can be controlled by the control unit (120). The display bar (130) can indicate the state of the speed gate (10) through a change in the color of the light source. The control unit (120) can control the color of the display bar corresponding to the standby state and the color of the display bar corresponding to the active state to be different. Comparing FIG. 4 and FIG. 5, it can be confirmed that the color of the display bar (130) has changed from blue to green.

The display bar (130) may be placed on the upper part of the main body (100) so that it can be easily recognized by the entrant and the manager monitoring the speed gate (10) via CCTV. In addition, the display bar (130) may be placed on the first main body (100A) and the second main body (100B) respectively so as to ensure that it can be easily recognized from various directions. Specifically, the display bar (130) includes a first display bar (130A) placed on the upper part of the first main body (100A) along the extension direction of the first main body (100A) and a second display bar (130B) placed on the upper part of the second main body (100B) along the extension direction of the second main body (100B). The first display bar (130A) and the second display bar (130B) may be placed to face each other with the passage (20) therebetween. The control unit (120) can control the light emitting body of the first display bar (130A) and the light emitting body of the second display bar (130B) facing it to be in the same state. That is, the light emitting body of the first display bar (130A) and the light emitting body of the second display bar (130B) facing it can be controlled so that the displayed color, color display timing, displayed time, etc. are the same.

In this embodiment, the indicator bar (130) can be controlled to indicate the position of the entrant within the passage (20). Since the indicator bar (130) is configured to have a length corresponding to the passage (20), the position of the entrant can be recognized from the outside as the light emitting body corresponding to the position of the entrant within the passage (20) emits light. In addition, since the indicator bar (130) is positioned at the upper part of the main body (100), even if the height of the entrant is smaller than the height of the main body (100) or the entrant moves with the upper body bent, and the entrant is not accurately recognized by the manager through the image, the entrant's entry and exit and the position within the passage (20) can be confirmed through the indicator bar (130).

The control unit (120) defines a tracking area based on the location and shape information of the entrant provided from the lidar sensor (140), and controls a light emitting body corresponding to the tracking area among a plurality of light emitting bodies of the indicator bar (130) to indicate the location of the entrant within the passage (20).

As illustrated in FIG. 6, the lidar sensor (140) outputs an optical pulse signal toward the passage (20), and receives an optical pulse signal reflected from an entrant passing through the passage (20) to generate information on the location and shape of the entrant. The lidar sensor (140) is configured to output an optical pulse signal and receive an optical pulse signal that is reflected and returned after a certain period of time. The lidar sensor (140) can track the location information of a reflection point by measuring the time of the optical pulse signal that is reflected and returned, and can generate shape information that constitutes the overall shape of the reflection point by collecting signals provided from a plurality of reflection points. That is, a plurality of reflection points form one shape, and a point cloud composed of information on a plurality of points in space can be generated. The reflected and returned time may be different when there is no entrant in the passage (20) and when there is an entrant in the passage (20), and the location information and shape information generated by the lidar sensor (140) may be different. Accordingly, the location and overall shape of the entrant can be estimated through the lidar sensor (140), and when the entrant moves along the passage (20), the change in the entrant's location along the passage (20) can be tracked.

The lidar sensor (140) can be selectively operated only when an entrant is authenticated, that is, when an entrant is expected to enter the passage (20). The lidar sensor (140) can be controlled by the control unit (120) not to operate in the standby state of the speed gate (10) but to operate in the activated state of the speed gate (10). The control unit (120) can control the lidar sensor (140) to operate when the identification information provided through the reader (110) is valid information. As a low-power system in which the lidar sensor (140) is selectively operated is applied, the overall power consumption of the speed gate (10) can be reduced. The control unit (120) can control the activated lidar sensor (140) to return to the standby state after a preset operation time has elapsed. However, it is not limited thereto, and when the control unit (120) detects that the passage of an entrant has ended, that is, when the location information and shape information of the entrant are no longer collected from the lidar sensor (140), the operation of the lidar sensor (140) can be stopped and controlled to be in a standby state.

The lidar sensor (140) may have a dual structure, which is respectively disposed in the first main body (100A) and the second main body (100B), to ensure the continuity of the estimation of the movement line of the entrant and to increase the accuracy of the measurement. Specifically, the lidar sensor (140) includes a first lidar sensor (140A) disposed in the first main body (100A) that emits a first optical pulse signal and generates information on the location and shape of the entrant based on the first optical pulse signal that is reflected and received, and a second lidar sensor (140B) disposed in the second main body (100B) that emits a second optical pulse signal and generates information on the location and shape of the entrant based on the second optical pulse signal that is reflected and received. The first lidar sensor (140A) and the second lidar sensor (140B) may each generate information on the location and shape of the entrant. Since the lidar sensor (140) has a dual structure, when one lidar sensor does not respond, the location of the person entering or exiting can be tracked through the other lidar sensor, so that it can be ensured that the movement path of the person entering or exiting is continuously tracked without interruption.

Here, when the first lidar sensor (140A) and the second lidar sensor (140B) simultaneously emit the first optical pulse signal and the second optical pulse signal, signal interference may occur between them, which may generate noise. In the present embodiment, the first lidar sensor (140A) and the second lidar sensor (140B) may be configured to operate sequentially at a predetermined interval. That is, the second optical pulse signal may be output with a predefined time interval with respect to the first optical pulse signal, and interference between the second optical pulse signal and the first optical pulse signal may be minimized.

The control unit (120) can selectively control the indicator bar (130) by defining a tracking area based on at least one of the location and shape information of the entrant generated from the first lidar sensor (140A) and the location and shape information of the entrant generated from the second lidar sensor (140B). The width of the tracking area is defined to cover the entire shape of the entrant, and the width of the tracking area can be defined to cover at least the passageway (20) and the indicator bar (130) located on both sides of the passageway (20). The control unit (120) can generate a tracking area having a size defined as described above based on the location of the entrant. In addition, the shape of the entrant may be different depending on the entrant, and the control unit (120) can define the tracking area by adjusting the width of the tracking area based on the shape information of the entrant. The control unit (120) can define the area covering the area of the passageway (20) and the indicator bar (130) defined on a plane as the entire area, and can define an area excluding the area defined as the tracking area in the entire area as the remaining area.

As shown in Fig. 7, a tracking area and a non-tracking area can be defined, respectively, and a light source of a display bar (130) corresponding to the tracking area and a light source of a display bar (130) corresponding to the remaining area can be defined. Here, the light source of the display bar (130) corresponding to the tracking area can mean a light source that overlaps the tracking area, and as the light source is selectively controlled, the location of an entrant within the passage (20) is identified through the light source.

The control unit (120) can control the color, brightness, or saturation of the light source corresponding to the tracking area and the light source corresponding to the remaining area to be different. Referring to FIG. 8, it can be seen that the light source corresponding to the tracking area displays a dark green color, and the light source corresponding to the remaining area displays a green color, so that the light source corresponding to the tracking area is emphasized compared to the light source corresponding to the remaining area. In other words, the location of the entrant can be displayed through the dark green color. The control unit (120) can set the tracking area in real time based on the location and shape information of the entrant provided through the lidar sensor (140) as the entrant moves, and can selectively control the light source corresponding to the set tracking area to display the location of the entrant. FIG. 9 illustrates a state in which the entrant has moved close to the exit of the passageway (20). It can be seen that the light source located in the direction of the exit of the passageway (20) displays a dark green color corresponding to the location of the entrant.

The control unit (120) may generate passage completion information of the corresponding entrant when it is determined that the entrant has completed passage. In an embodiment, the control unit (120) may determine that the entrant has completed passage when the entrant's location information and shape information are not collected through the lidar sensor (140), but is not limited thereto. The control unit (120) may store the entrant's identification information and corresponding passage completion information in a data storage unit (not shown) or transmit it to a monitoring server (not shown) of a manager connected through a network so that information about the entrant is recorded in the monitoring server. In addition, the control unit (120) may control the speed gate (10) to be in a standby state. The display color of the display bar (130) may be changed, and the gate door (170) may be controlled to be in a closed state.

In some embodiments, the control unit (120) may define an area previously defined as a tracking area as a movement area as the entrant moves along the passageway (20). That is, as the entrant moves along the passageway (20), a certain range of the tracking area is redefined, and some areas previously included in the tracking area are excluded from the newly defined tracking area. The control unit (120) may define the area excluded in this way as a movement area. That is, as the entrant moves along the passageway (20), the movement area continues to increase. The control unit (120) may control the color, brightness, or saturation of a light source corresponding to the movement area to indicate the movement direction of the entrant. Specifically, the control unit (120) may control the color, brightness, or saturation of the light source corresponding to the movement area to change stepwise from the entrance to the exit. As the change in the color, brightness, or saturation of the light source corresponding to the movement area is displayed stepwise, it is possible to confirm the direction in which the entrant has moved even if he or she is located at a specific point along the passageway (20). Referring to Fig. 10, when an entrant is positioned at the exit side of the passage (20), an area other than the tracking area is sequentially defined as a movement area. It can be seen that the light source corresponding to this movement area displays a color different from the green displayed conventionally, but is controlled so that the brightness increases sequentially from the entrance to the exit. An administrator monitoring the speed gate (10) through CCTV can confirm the movement direction of an entrant with just a still image. Accordingly, it can be supported for the administrator to more easily identify the entry and exit and movement line of an entrant.

Again, referring to FIGS. 2 and 3, the object recognition sensor (150) can recognize an object approaching at least one of the entrance and exit of the passage (20). The speaker (160) can be configured to output sound toward the object. Although FIGS. 2 and 3 illustrate that the object recognition sensor (150) and the speaker (160) are positioned at the entrance of the passage (20), the object recognition sensor (150) and the speaker (160) are not limited thereto, and the object recognition sensor (150) and the speaker (160) can also be positioned at the exit of the passage (20).

When an object is detected approaching at least one of the entrance and exit of the passage through the object recognition sensor (150) while an entrant is positioned inside the passage (20), the control unit (120) can output at least one of a warning sound and a guidance message through the speaker (160). The object recognition sensor (150) may be an ultrasonic sensor that recognizes an object approaching at least one of the entrance and exit of the passage through ultrasonic waves, but is not limited thereto. In some embodiments, the object recognition sensor (150) may be an infrared sensor that recognizes an object using infrared waves. Here, the guidance message may include requesting that the object be prohibited from approaching and requesting that the object step back.

In addition, the control unit (120) may keep the gate door (170) closed when an object enters the exit of the passage (20), display a red light through the indicator bar (130), and output at least one of a warning sound and a guidance message through the speaker (160). Here, the guidance message may include informing the object that entry toward the exit is not permitted. The control unit (120) guides another object (entrant) to approach the speed gate (10) after the current entrant has completed passage through the object recognition sensor (150) and the speaker (160), and blocks the reverse passage of the entrant into the passage through the exit, thereby ensuring that the stable access control management of the speed gate (10) is performed.

As described above, the speed gate including the entrance location indicator bar of the present invention can identify the location of the entrance/exiter within the passage through the light source, and the entrance/exiter can pass through the passage while confirming his/her location, and can support the entrance/exiter to pass through the passage within an appropriate time. In addition, the indicator bar can be easily recognized by the manager monitoring the speed gate through CCTV. Accordingly, it can support the manager to easily identify whether the entrance/exiter has entered the passage and the location of the entrance/exiter within the passage. In addition, the speed gate including the entrance/exiter location indicator bar of the present invention can confirm the direction of movement of the entrance/exiter even if the entrance/exiter is located at a specific point in the passage by gradually displaying the change in color, brightness, or saturation of the light source corresponding to the movement area. Accordingly, it can support the manager to easily identify the movement direction of the entrance/exiter with only a still image without monitoring all the captured CCTV images. In addition, the speed gate including the entrance/exiter location indicator bar of the present invention can reduce power consumption by applying a low-power system in which a lidar sensor is selectively activated only when the entrance/exiter is authenticated. In addition, the speed gate including the entrance/exit location indicator of the present invention allows access of other objects (entrants) after the passage of the currently passing entrant is completed, and blocks reverse passage of entrants entering the passage through the exit, thereby enabling stable entry/exit control management of entrants.

Hereinafter, an access control method using a speed gate including an entry/exit location indicator bar according to some embodiments of the present invention will be described.

An access control method according to some embodiments of the present invention corresponds to an access control method performed at a speed gate including an entry/exit location indicator bar, and for an explanation of the access control method according to the present embodiment, reference may be made to FIGS. 1 to 10 and the descriptions related thereto.

Fig. 11 is a flow chart of an access control method according to some embodiments of the present invention. Fig. 12 is a flow chart showing detailed steps of a step of tracking the movement line of an entrant passing through a passage and displaying it through a display bar.

Referring to FIG. 11, an access control method according to some embodiments of the present invention includes a step of acquiring identification information from an entrant near an entrance of a passage through a reader (S100); a step of determining validity of the identification information of the entrant (S110); a step of opening a gate door of the speed gate to permit passage of the entrant if the identification information is valid (S120); a step of tracking a movement line of an entrant passing through the passage and displaying the traced line through an indicator bar (S130); and a step of closing the gate door and generating passage completion information of the entrant if passage of the entrant is completed (S140).

First, identification information is acquired from entrants near the entrance of the passage through a reader.

In this step (S100), the reader (110) can read the authentication means of an entrant entering and exiting the passage to obtain identification information. The reader (110) is configured to include at least one of a touch monitor, a fingerprint recognition device, a facial recognition device, a barcode reader, an NFC reader, and an RF reader. In this step (S100), the biometric information (fingerprint, pupil, blood vessel, face, etc.) of the entrant can be obtained as identification information through the touch monitor, the fingerprint recognition device, and the facial recognition device. In addition, in this step (S100), a pre-issued authentication code and an authentication tag can be obtained as identification information through the barcode reader, the NFC reader, and the RF reader.

In addition, in the embodiment, the speed gate (10) is a gate for controlling the entry and exit of the entrant into the radiation management area, and the entrant may carry a dosimeter. The reader (110) is configured to exchange data with the entrant's dosimeter to measure at least one of the entrant's radiation dose and the entrant's accumulated dose. Therefore, in step (S100), at least one of the entrant's radiation dose and the entrant's accumulated dose can be acquired as identification information through the reader (110).

Next, the validity of the identification information of the entrant is determined (S110), and if the identification information is valid, the gate door of the speed gate is opened to allow passage of the entrant (S120).

In step (S110), the validity of the identification information can be determined by whether the acquired identification information matches the previously stored information. If the previously stored information and the identification information do not match, the identification information is determined to be invalid. In addition, if the identification information includes at least one of the radiation dose of the entrant and the cumulative dose of the entrant, the validity of the identification information can be determined by whether at least one of the radiation dose of the entrant and the cumulative dose of the entrant exceeds the allowable dose. If it exceeds the allowable dose, the identification information is determined to be invalid.

In step (S120), if the identification information is valid, the speed gate changes from a standby state to an activated state. That is, the gate door of the speed gate is opened, and passage of an entrant is permitted. If the identification information is invalid, the control unit (120) closes the gate door (170) to maintain the speed gate (10) in a standby state. This change in the state of the speed gate (10) can be identified through a color change in the display bar (130). That is, in this step (S120), the control unit (120) can control the color of the display bar corresponding to the standby state and the color of the display bar corresponding to the activated state to be different.

Next, the movement path of people passing through the passage is tracked and displayed using a display bar (S130).

The indicator bar (130) includes a plurality of light-emitting elements arranged along the passage. The movement line of the entrant can be indicated by selectively controlling specific light-emitting elements. The position of the entrant passing through the passage can be collected through the lidar sensor (140), and the indicator bar (130) can be selectively controlled based on the information generated by the lidar sensor (140). Here, the lidar sensor can be selectively operated in the activated state of the speed gate (10).

Referring to FIG. 12, the step (S130) includes a step (S132) of outputting a light pulse signal toward a person entering or exiting through the passage, and receiving a light pulse signal reflected from the person entering or exiting through the passage to generate information on the location and shape of the person entering or exiting; a step (S134) of defining a tracking area according to the provided information on the location and shape of the person entering or exiting; and a step (S136) of selectively controlling a light emitting body corresponding to the tracking area among a plurality of light emitting bodies, thereby tracking the movement of the person entering or exiting and displaying it through an indicator bar.

In the step (S136) of selectively controlling a light source corresponding to the tracking area among a plurality of light sources, the light source corresponding to the tracking area among the plurality of light sources of the display bar may be controlled to have a different color, brightness, or saturation from the light sources corresponding to the remaining areas other than the tracking area.

In addition, the present step (S130) may further include a step of defining a conventional tracking area as a movement area as the entrant moves through the passage, and the control unit controls the color, brightness, or saturation of a light emitting body corresponding to the movement area to change stepwise from the entrance to the exit.

Next, when the passage of the entrant is completed, the gate door is closed and information on the completion of passage of the entrant is generated (S140).

In this step (S140), when the location information and shape information of the entrant are not collected through the lidar sensor (140), the entrant's passage is determined to be completed. If it is determined that the entrant has completed passage, passage completion information of the entrant can be generated. The identification information of the entrant and the corresponding passage completion information are stored in a data storage unit (not shown) or transmitted to a monitoring server (not shown) of a manager connected through a network so that information about the entrant is recorded in the monitoring server. In this step (S140), the display bar (130) can be changed so that the display color corresponds to the standby state, and the gate door (170) can be controlled to be in a closed state. That is, the speed gate (10) returns to the standby state and manages the entry and exit of a new entrant.

The access control method according to the present embodiment may further include a step of outputting at least one of a warning sound and a guidance message through a speaker (160) when an object's approach to at least one of the entrance and exit of the passage is detected through an object recognition sensor (150) while an entrant is positioned inside the passage. Here, the guidance message includes a request to prohibit access to the object and to step back.

In addition, the access control method according to the present embodiment may further include a step of keeping the gate door (170) closed, displaying a red light through the indicator bar (130), and outputting at least one of a warning sound and a guidance message through the speaker (160) when an object enters the exit of the passage (20). Here, the guidance message may include informing the object that entry toward the exit is not permitted.

That is, the access control method according to the embodiment can induce another object (entrant) to approach the speed gate (10) after the passage of the currently passing entrant has been completed, and block the reverse passage of the entrant entering the passage through the exit, thereby enabling stable access control management of the speed gate (10).

The above description is merely an illustrative description of the technical idea of the present embodiment, and those with ordinary skill in the art to which the present embodiment pertains may make various modifications and variations without departing from the essential characteristics of the present embodiment.
