Description

Technical Field

[0001] One embodiment of the present invention relates to a belt partition stand used for guiding the flow of people and a belt partition system using a plurality of belt partition stands.

Background Art

[0002] In recent years, in order to prevent the spread of infectious diseases such as influenza or novel coronavirus, physical distancing that maintains a certain distance or more between people has become important. For example, in stores or facilities, in order to ensure physical distancing, means such as tapes or seals indicating waiting areas are often pasted on the floor to call the attention of users to physical distancing.

[0003] Also, in stores or facilities, belt partition stands may be used to control the flow of people (see, for example, Patent Document 1). That is, a plurality of belt partition stands are used to stretch a belt between the belt partition stands to form a path for people to move forward. Thereby, the flow of people can be controlled.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In order to ensure a physical distance using a belt partition stand as described in Patent Document 1, it is necessary to indicate a waiting area on the floor surface in the same manner as described above. Although the belt partition stand has the advantage of being able to freely form a path by combination, this advantage is lost if it does not indicate a waiting area on the floor surface. Also, when a tape is stuck on the floor surface to indicate a waiting area, people will always step on the tape, so the tape will deteriorate and regular replacement will be required.

[0006] In view of the above problems, one object of an embodiment of the present invention is to provide a belt partition stand capable of ensuring a physical distance. Another object is to provide a belt partition system capable of ensuring a physical distance using a plurality of belt partition stands.

Means for Solving the Problems

[0007] A partition stand according to an embodiment of the present invention includes a pole portion and a head portion connected to one end of the pole portion and configured to removably accommodate a belt. The head portion includes a sensor for detecting a person and an information processing unit for counting the number of people detected by the sensor.

[0008] The head portion may further include a display lamp and a determination unit that transmits a display lamp control signal to the display lamp based on the number of people counted by the information processing unit.

[0009] A partition system according to an embodiment of the present invention is a belt partition system in which a first belt partition stand and a second belt partition stand are connected via a belt. Each of the first belt partition stand and the second belt partition stand includes a pole portion and a head portion connected to one end of the pole portion and configured to accommodate a belt in a drawable manner. The head portion of the first belt partition stand includes a first sensor for detecting a person and a first information processing unit for counting a first number of people detected by the first sensor. The head portion of the second belt partition stand includes a second sensor for detecting a person and a second information processing unit for counting a second number of people detected by the second sensor. The head portion of the first belt partition stand further includes a determination unit for calculating a difference between the second number and the first number.

[0010] A communication cable for communicably connecting the first belt partition stand and the second belt partition stand may be embedded in the belt.

[0011] The head portion of the first belt partition stand may further include an indicator lamp capable of lighting a plurality of colors based on the difference between the second number and the first number.

[0012] The head portion of the first belt partition stand further includes a display device for performing a warning display based on the difference between the second number and the first number.

Mode for Carrying Out the Invention

[0015] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. Note that the embodiments are merely examples, and those that can be easily conceived by those skilled in the art by appropriately changing while maintaining the gist of the invention are naturally included in the scope of the present invention. Also, for the purpose of making the description clearer, the drawings may schematically show the width, thickness, or shape of each part compared to the actual aspect. However, the illustrated shapes and the like are merely examples and do not limit the interpretation of the present invention.

[0016] In this specification, for convenience of explanation, the terms "upper" or "above" or "lower" or "below" are used for explanation, but these terms only explain the vertical relationship of each component. For example, when a structure is installed, the installation surface side where the structure is usually installed is regarded as "lower" or "below".

[0017] In this specification, the characters such as "first", "second", or "third" attached to each component are convenient identifiers used to distinguish each component, and unless otherwise specified, they do not have any further meaning.

[0018] In this specification and the drawings, when collectively representing a plurality of identical or similar components, the same reference numerals are used. When separately representing each of these plurality of components, they may be represented with appended lowercase or uppercase alphabets. Also, when separately representing a plurality of parts within one component, hyphens and natural numbers may be used.

[0019] [1. Configuration of Belt Partition Stand 10] FIG. 1 is a schematic perspective view showing the configuration of a belt partition stand 10 according to an embodiment of the present invention. Specifically, FIGS. 1(A) and 1(B) show the same belt partition stand 10 and are perspective views with viewpoints differing by approximately 90°. The belt partition stand 10 includes a base portion 100, a pole portion 200, and a head portion 300. One end of the pole portion 200 is connected to the base portion 100, and the other end of the pole portion 200 is connected to the head portion 300. When the belt partition stand 10 is in use, the base portion 100 is placed on the floor surface, and the head portion 300 is supported by the pole portion 200. The base portion 100 is preferably flat plate-shaped so as to be stably placed on the floor surface. The pole portion 200 is, for example, cylindrical, but is not limited thereto. Although not shown, the pole portion 200 may be provided with a length adjustment mechanism for adjusting the length of the pole portion 200. By providing the length adjustment mechanism in the pole portion 200, the height from the floor surface to the head portion 300 can be adjusted.

[0020] Note that the belt partition stand 10 may have a configuration in which the base portion 100 is not provided. In this case, a pole insertion opening is provided on the ground, and the belt partition stand 10 is used with one end of the pole portion 200 inserted into the pole insertion opening.

[0021] As shown in FIG. 1, the head unit 300 includes a belt 310, a belt terminal portion 320, a connection terminal portion 330, a sensor 340, a display device 350, and a display lamp 360. One end of the belt 310 is connected to the belt terminal portion 320, and the other end of the belt 310 is connected to a reel (not shown) provided inside the head unit 300. The reel is rotatably provided within the head unit 300 and is biased to draw the belt 310 into the head unit 300, and can wind up the belt 310 connected to the reel. Therefore, the belt 310 can be drawn out from the head unit 300 or the belt 310 can be accommodated in the head unit 300 through the opening provided in the head unit 300. Note that since the width of the belt terminal portion 320 connected to the belt 310 is larger than the width of the opening, the belt terminal portion 320 is not drawn into the inside of the head unit 300 even when the belt 310 is accommodated in the head unit 300.

[0022] The substantially columnar belt terminal portion 320 can be fitted into the cylindrical connection terminal portion 330 having a slit. That is, by fitting the belt terminal portion 320 of one belt partition stand 10 into the connection terminal portion 330 of another belt partition stand 10, two belt partition stands 10 can be connected to each other. The belt terminal portion 320 is fitted into the connection terminal portion 330 with the belt 310 passed through the slit. Since the width of the slit is smaller than the width of the belt terminal portion 320, the belt terminal portion 320 is fixed at the position of the connection terminal portion 330. Therefore, the belt 310 drawn out from the head unit 300 is stretched between two adjacent belt partition stands 10.

[0023] Note that a communication cable 311 is embedded in the belt 310, and the communication cable 311 may be electrically connected to a terminal disposed at the belt terminal portion 320. When the belt terminal portion 320 and the connection terminal portion 330 are fitted together, a terminal provided at one end of the belt terminal portion 320 and a terminal provided at the stopper portion of the connection terminal portion 330 are electrically connected. Therefore, when two belt partition stands 10 are connected to each other, the two belt partition stands 10 can communicate with each other via the communication cable 311. Note that even when three or more belt partition stands 10 are connected, they can communicate with each other.

[0024] The belt terminal portion 320 and the connection terminal portion 330 are not limited to the above-described configuration. The belt terminal portion 320 and the connection terminal portion 330 may have any configuration as long as the terminals of the belt terminal portion 320 and the terminals of the connection terminal portion 330 can come into contact with each other when two belt partition stands 10 are connected. Therefore, for example, a configuration in which the belt terminal portion 320 and the connection terminal portion 330 are connected by magnetic force is also possible.

[0025] Not only the communication cable 311 but also a power cable may be embedded in the belt 310. In this case, a power outlet may be provided in one belt partition stand 10, and power may be supplied to other belt partition stands 10 via the power cable. In the above-described configuration, a plurality of belt partition stands 10 show communication connection by a wired communication cable, but wireless communication connection using the Internet or Wi-Fi (registered trademark) may also be possible.

[0026] The belt partition stand 10 may be provided with a rechargeable battery unit such as a lithium ion battery. The battery unit can be accommodated in the internal space of the pole portion 200, for example. By providing the battery unit, the belt partition stand 10 can operate independently. Note that a solar panel may be incorporated into a part of the pole portion 200 so that the lithium battery can be charged.

[0027] The sensor 340 is a so-called human presence sensor that can detect the presence of a person. The sensor 340 can detect, for example, infrared rays corresponding to the body temperature radiated from a person and detect the presence of a person. However, the sensor 340 can not only detect the presence of a person within the detection range, but also detect the position of the person within the detection range (for example, the angle from the central axis of the sensor 340 and the distance from the sensor 340 to the person), and can output a detection signal representing the position of the person in terms of angle and distance. Therefore, the sensor 340 may be configured to be able to irradiate laser or ultrasonic waves in addition to detecting infrared rays and detect the reflected waves thereof. For example, the sensor 340 may be configured to include a laser rangefinder. Further, although the sensor 340 is installed on the side surface of the head portion 300, a detection angle adjustment mechanism for adjusting the maximum detection range of the sensor 340 may be provided. By providing a detection angle adjustment mechanism in the head portion 300, the maximum detection range of the sensor 340 can be adjusted according to the flow of people, and the sensitivity of the sensor 340 can be adjusted. For example, as the detection angle adjustment mechanism, the maximum detection range of the sensor 340 can be adjusted by providing a shielding protrusion that can limit the maximum detection range.

[0028] The display device 350 is a device that can display an image. For example, as the display device 350, a liquid crystal display device or an OLED (Organic Light-Emitting Diode) display device or the like can be used. Further, it is preferable that the display device 350 is provided with an input interface such as a touch panel. Further, although the display device 350 is installed on the side surface of the head portion 300, it is preferable that the display direction of the display device 350 can be set by the user. Although details will be described later, in the display device 350, not only the determination conditions based on the detection signal of the sensor 340 and the setting and confirmation of the magnitude of the physical distance between two adjacent belt partition stands 10, but also a warning display or the like can be performed when the physical distance is not secured.

[0029] The display lamp 360 is a light source such as an LED. It is preferable that the display lamp 360 can be lit in multiple colors, such as blue, yellow, or red, so that it is possible to visually recognize step by step whether a physical distance is ensured. That is, the display lamp 360 can visually notify information regarding the physical distance. Note that the display lamp 360 may not only be lit but also blink. The display lamp 360 can set the lighting intensity according to the brightness of external light. The brightness of the external light can be detected by a solar panel.

[0030] Although not shown in the figure, the belt partition stand 10 may be provided with a power button or a voice output unit, etc. By pressing the power button, the power of the belt partition stand 10 may be supplied, and it is preferable that the power button is provided with a cover for preventing malfunction. Also, the voice output unit includes, for example, a speaker that plays and outputs sound from a recorded sound source. That is, the voice output unit can aurally notify information regarding the physical distance. Note that the sound source can be selected according to the lighting color of the display lamp 360.

[0031] FIG. 2 is a block diagram for explaining a part of the configuration of the head unit 300 of the belt partition stand 10 according to an embodiment of the present invention. The head unit 300 further includes a control unit 370 and a storage unit 380 that control the display device 350 and the display lamp 360 based on the detection signal of the sensor 340. The control unit 370 can control the functions of the information processing unit 371 and the determination unit 372 by executing a program on a computer. The computer includes, for example, a Central Processing Unit (CPU), a Micro Processing Unit (MPU), a Graphics Processing Unit (GPU), and a Digital Signal Processor (DSP), and further includes a Random Access Memory (RAM) or a Read Only Memory (ROM) as a storage device. A program is stored in the storage device. The storage unit 380 is a storage that can store a set value 381 and an ID number 382 representing the determination conditions determined by the determination unit 372. For example, as the storage unit 380, a Hard Disk Drive (HDD), a Solid State Drive (SSD), a flash memory, or the like can be used, but not limited thereto. Note that the storage unit 380 may be included in the storage device.

[0032] The information processing unit 371 can set the ID number of the belt partition stand 10. Further, the information processing unit 371 can count the number of people detected by the sensor 340 and output the number of passing people N who have passed in front of the belt partition stand 10. Details of this function of the information processing unit 371 will be described later.

[0033] The determination unit 372 can execute a determination using the number of passing people N output by each of the information processing units 371 of two adjacent belt partition stands 10. Specifically, the determination unit 372 calculates the difference in the number of passing people N output by each of the information processing units 371 of two adjacent belt partition stands 10, and executes a determination to compare it with the set value 381. Further, the determination unit 372 generates a display lamp control signal corresponding to the determination result and controls the display lamp 360. Note that the determination conditions executed by the determination unit 372 will be described later.

[0034] The storage unit 380 can store the set value 381 and the ID number 382 necessary when using the belt partition stand 10. The set value 381 includes values used for the set detection range and determination conditions.

[0035] In the above description, the configuration in which the control unit 370 and the storage unit 380 are provided in the head unit 300 has been described. However, the control unit 370 or the storage unit 380 may be provided in the pole unit 200 or may be provided in a server on the connected network.

[0036] [2. Usage mode of the belt partition stand 10] FIG. 3 is a schematic plan view for explaining the usage mode (belt partition system) of the belt partition stand 10 according to an embodiment of the present invention. In FIG. 3, two belt partition stands 10 (the first belt partition stand 10-1 and the second belt partition stand 10-2) are connected. However, the number of belt partition stands 10 to be connected is not limited to two. The number of belt partition stands 10 connected during use may be n (n is an integer of 2 or more).

[0037] As shown in FIG. 3, the first belt partition stand 10-1 and the second belt partition stand 10-2 are arranged with a span L. The second belt terminal portion 320-2 of the second belt partition stand 10-2 is fitted to the first connection terminal portion 330-1 of the first belt partition stand 10-1. Therefore, the second belt 310-2 of the second belt partition stand 10-2 is stretched between the first belt partition stand 10-1 and the second belt partition stand. Here, the flow of people is in the direction from the first belt partition stand 10-1 to the second belt partition stand 10-2.

[0038] When the first belt partition stand 10-1 and the second belt partition stand 10-2 are connected and the power supplies of the first belt partition stand 10-1 and the second belt partition stand 10-2 are turned on, the ID numbers of the first belt partition stand 10-1 and the second belt partition stand 10-2 are set via the second communication cable 311-2 embedded in the second belt 310-2. The ID number 382 is assigned in the order in which the belt partition stands 10 are connected and stored in the storage unit 380. By assigning the ID number 382 to each belt partition stand 10, it becomes possible to set the detection condition of the sensor 340 and the magnitude of the physical distance (distance per person) d for each belt partition stand 10. These set values 381 are also stored in the storage unit 380. Hereinafter, it will be described assuming that the quotient of L / d is 3. The quotient of L / d corresponds to the allowable number of people between the first belt partition stand 10-1 and the second belt partition stand 10-2. Therefore, hereinafter, for the sake of convenience, the quotient of L / d will be described as the allowable number of people M.

[0039] The first sensor 340-1 of the first belt partition stand 10-1 detects a person passing in front of the first belt partition stand 10-1. As shown in FIG. 3, four persons, i.e., the first person 500-1 to the fourth person 500-4, are passing in front of the first belt partition stand 10-1. Therefore, the first information processing unit 371-1 of the first belt partition stand 10-1 counts the number of persons detected by the first sensor 340-1, and sets the first passing person number N(1) of the first belt partition stand 10-1 to 4.

[0040] The second sensor 340-2 of the second belt partition stand 10-2 detects a person passing in front of the second belt partition stand 10-2. As shown in FIG. 3, one person, i.e., the first person 500-1, is passing in front of the second belt partition stand 10-2. Therefore, the second information processing unit 371-2 of the second belt partition stand 10-2 counts the number of persons detected by the second sensor 340-2, and sets the second passing person number N(2) of the second belt partition stand 10-2 to 1.

[0041] The first determination unit 372-1 of the first belt partition stand 10-1 receives the second passing person number N(2) via the second communication cable 311-2 of the second belt partition stand 10-2.

[0042] The first determination unit 372-1 calculates N(1) - N(2) as the number of people between the first belt partition stand 10-1 and the second belt partition stand 10-2. Here, N(1) - N(2) corresponds to the number of people S within the span. That is, S = N(1) - N(2) = 3 is obtained, and it can be seen that there are 3 people in the span L between the first belt partition stand 10-1 and the second belt partition stand 10-2. The first determination unit 372-1 compares the allowable number of people M with the number of people S within the span, and sends a display lamp control signal to the first display lamp 360-1 according to a predetermined determination condition. Here, since the allowable number of people M and the number of people S within the span have the same value, the first determination unit 372-1 sends a display lamp control signal for the first display lamp 360-1 to light up in red. The fifth person 500-5 trying to pass through the first belt partition stand 10-1 can visually understand that they cannot pass through the first belt partition stand 10-1 by confirming that the first display lamp 360-1 is lit in red.

[0043] When the difference (M - S) between the allowable number of people M and the number of people S within the span is 1, the first determination unit 372-1 sends a display lamp control signal for the first display lamp 360-1 to light up in yellow in order to prompt people passing in front of the first belt partition stand 10-1. Also, when the difference between the allowable number of people M and the number of people S within the span is greater than 1, the first determination unit 372-1 sends a display lamp control signal for the first display lamp 360-1 to light up in blue in order to permit passage in front of the first belt partition stand 10-1. In this way, the person 500 trying to pass in front of the first belt partition stand 10-1 can confirm the lighting color of the first display lamp 360-1 and determine whether they can pass in front of the first belt partition stand 10-1.

[0044] Also, when the number of people S within the span is greater than the allowable number of people M, the first determination unit 372-1 transmits a display lamp control signal for causing the first display lamp 360-1 to blink red. As a result, the person 500 who has passed through the first belt partition stand 10-1 can confirm the red blinking of the first display lamp 360-1 and understand that the number of people in the span L between the first belt partition stand 10-1 and the second belt partition stand 10-2 exceeds the allowable number of people M, and can stop once. At this time, a warning such as "The maximum number of people has been exceeded. Please stop once to ensure physical distance." may be displayed on the first display device 350-1. Also, when an audio output unit is provided at the first belt partition stand 10-1, a warning sound may be emitted from the audio output unit. Also, the second display lamp 350-2 of the second belt partition stand 10-2 may be caused to blink blue to prompt the person 500 who is about to pass through the second belt partition stand 10-2 to move forward.

[0045] In the above description, a belt partition system using two belt partition stands 10 has been described as an example. However, the determination condition for the allowable number of people M(n-1) with respect to the number of people S(n-1) within the (n-1)-th span (i.e., N(n-1)-N(n)) between the (n-1)-th belt partition stand 10-n-1 and the n-th belt partition stand 10-n in n (n is an integer of 2 or more) belt partition stands 10 and the lighting color of the (n-1)-th display lamp 360-n-1 are, for example, as shown in Table 1. The person 500 who is about to pass in front of the (n-1)-th belt partition stand 10-n-1 can confirm the (n-1)-th display lamp 360-n-1 of the (n-1)-th belt partition stand 10-n-1 and can determine whether to move forward. However, the determination condition and the lighting color are not limited to Table 1.

[0046]

Table 1

[0047] Also, in the case of a belt partition system using three or more (i.e., n ≥ 3) belt partition stands 10, determination can also be executed using the number of people within the spans of two adjacent spans L. For example, the determination conditions in the (n - 1)-th determination unit 372-(n - 1) and the lighting color of the (n - 1)-th display lamp 360-(n - 1) located between two adjacent spans L are, for example, as shown in Table 2. However, the determination conditions and lighting colors are not limited to Table 2.

[0048]

Table 2

[0049] Under the determination conditions shown in Table 2, the (n - 1)-th display lamp 360-(n - 1) is not only lit in blue but also controlled to blink in blue. In this case, not only the number of people S(n - 1) within the (n - 1)-th span but also the number of people S(n - 1) within the (n - 2)-th span where the person 500 trying to pass through the (n - 1)-th belt partition stand 10-n-1 exists may be considered. That is, when the number of people S(n - 2) within the (n - 2)-th span (i.e., N(n - 2) - N(n - 1)) satisfies S(n - 2) < M(n - 2) - 1, there is sufficient space in the (n - 2)-th span L(n - 2), so a physical distance can be ensured. Therefore, the (n - 1)-th display lamp 360-(n - 1) is lit in blue, and the person 500 can move forward as usual. However, when the number of people S(n - 2) within the (n - 2)-th span satisfies S(n - 2) ≥ M(n - 2) - 1, there is not enough space in the (n - 2)-th span L(n - 2), so it becomes difficult to ensure a physical distance. Therefore, the (n - 1)-th display lamp 360-(n - 1) blinks in blue, and the person 500 can be prompted to move forward.

[0050] Here, referring to FIGS. 4 and 5, the person counting process (generation process of the number of passing people N) executed by the control unit 370 (specifically, the information processing unit 371) will be described.

[0051] FIG. 4 is a schematic diagram for explaining the detection signal of the sensor 340 of the belt partition stand 10 according to an embodiment of the present invention and the set detection range. As shown in FIG. 4(A), the sensor 340 can output a detection signal with the detection angle θ (°) and distance r (m) of the human position. Further, as shown in FIG. 4(B), the sensor 340 has a maximum detection range, and the maximum detection range is at an angle of ±α (°) and a distance l dm (m) from the central axis of the sensor 340. In the belt partition stand 10, a part of the maximum detection range of the sensor 340 is set as the set detection range. That is, the set detection range of the sensor 340 is at an angle of ±β (°) (β < α) and a distance l b (m) (l b < l dm ). By setting the set detection range of the sensor 340 in this way, it becomes possible to perform the counting process while tracking a person.

[0052] FIG. 5 is a flowchart of the counting process of the person detected by the sensor 340 executed by the control unit 370 of the belt partition stand 10 according to an embodiment of the present invention. The counting process is started when a person is detected by the sensor 340.

[0053] In step S110, it is determined whether the person 500 exists within the set detection range of the sensor 340. That is, the information processing unit 371 determines whether the detection angle θ1 (°) of the person 500 at the first time (t1) satisfies -β ≦ θ1 ≦ +β and the distance r1 (m) of the person 500 at t1 satisfies r1 ≦ l b . If the person 500 exists within the set detection range of the sensor 340 (step S110: YES), step S120 is executed. If the person 500 does not exist within the set detection range of the sensor 340 (step S110: NO), step S110 is executed again.

[0054] In step S120, after a predetermined time has elapsed, it is determined whether the person 500 is moving in the traveling direction. That is, the information processing unit 371 calculates the moving distance D2 = r2sinθ2 - r1sinθ1 of the person 500 from time t1 to time t2 based on the detection angle θ2 (°) and distance r2 (m) of the person 500 at the second time (t2) and the detection angle θ1 (°) and distance r1 (m) of the person 500 at t1, and determines whether D2 satisfies D2 > F d (any positive value). If the person 500 is moving in the traveling direction (step S120: YES), step S130 is executed. If the person 500 is not moving in the traveling direction (step S120: NO), since there is a possibility that the person 500 is moving in the direction opposite to the traveling direction, step S120 is executed again.

[0055] In step S130, the number of people detected by the sensor 340 (the number of people passing through the belt partition stand 10) is integrated. That is, the information processing unit 371 sets the value obtained by adding 1 to the number of passing people N as the new number of passing people N. Immediately after the power of the belt partition stand 10 is turned on, since no person is detected by the sensor 340, N = 0.

[0056] In step S140, after a predetermined time has elapsed, it is determined whether the person 500 is outside the set detection range in the traveling direction. That is, the information processing unit 371 determines whether the detection angle θ3 (°) of the person 500 at the third time (t3) satisfies θ3 > +β. If the person 500 is outside the set detection range in the traveling direction (step S140: YES), the person counting process is terminated. If the person 500 is not outside the set detection range in the traveling direction (step S140: NO), since there is a possibility that the person 500 has stopped once or is moving in the direction opposite to the traveling direction, step S150 is executed.

[0057] In step S150, it is determined whether the person 500 is moving in the direction opposite to the traveling direction. That is, the information processing unit 371 calculates the moving distance D3 = r3sinθ3 - r2sinθ2 of the person 500 from t2 to t3 from the detection angle θ3 (°) and distance r3 (m) of the person 500 at t3 and the detection angle θ2 (°) and distance r2 (m) of the person 500 at t2, and determines whether D3 satisfies D3 < B d (any negative value). If the person 500 is moving in the direction opposite to the traveling direction (step S150: YES), step S160 is executed. Also, if the person 500 is not moving in the direction opposite to the traveling direction (step S150: NO), since the person 500 may have stopped once, step S140 is executed again.

[0058] In step S160, it is determined whether the person 500 is outside the set detection range. That is, the information processing unit 371 determines whether the detection angle θ3 (°) of the person 500 at t3 satisfies θ3 < -β, or whether the detection distance r3 (m) of the person 500 satisfies r3 > l b . If the person 500 is outside the set detection range (step S160: YES), step S170 is executed. Also, if the person 500 is within the set detection range (step S160: NO), step S140 is executed again.

[0059] In step S170, the number of people detected by the sensor 340 (the number of people passing through the belt partition stand 10) is subtracted. That is, the information processing unit 371 sets the value obtained by subtracting 1 from the number of passing people N as the new number of passing people N. The person 500 who moves in the direction opposite to the traveling direction in step S150 and exists outside the set detection range of the sensor 340 in step S160 is considered to have returned without moving in the traveling direction. Therefore, step S170 is executed to restore the number of passing people N integrated in step S130.

[0060] As described above, the belt partition stand 10 according to an embodiment of the present invention can detect a person passing through the sensor 340, and can count the number of people passing through the belt partition stand 10 by the control unit 370 (specifically, the information processing unit 371) while tracking the person. Further, a belt partition system using a plurality of belt partition stands 10 can control the number of people between two adjacent belt partition stands 10. Therefore, the belt partition stand 10 can control the flow of people and promote a physical distance.

[0061] The embodiments of the present invention can be implemented by appropriately combining configurations as long as they do not conflict with each other. Further, based on the embodiments, those in which those skilled in the art have appropriately added, deleted, or changed the design of the configuration, or added, omitted, or changed the conditions of the process are also included in the scope of the present invention as long as they have the gist of the present invention.

[0062] Even other operational effects different from those brought about by the above-described embodiments, those that are obvious from the description of this specification or that can be easily predicted by those skilled in the art are naturally understood to be brought about by the present invention.
