Description

One embodiment of the present invention relates to a belt partition stand used to guide the flow of people and a belt partition system using multiple belt partition stands.

In recent years, physical distancing, or maintaining a certain distance between people, has become important in order to prevent the spread of infectious diseases such as influenza or the new coronavirus. For example, in stores and facilities, in order to ensure physical distancing, measures are often taken to remind users to maintain physical distance by placing tape or stickers on the floor indicating waiting areas.

In addition, in stores or facilities, the flow of people may be controlled using belt partition stands (see, for example, Patent Document 1). That is, multiple belt partition stands are used, and a belt is stretched between the belt partition stands to form a path for people to move along. This makes it possible to control the flow of people.

JP 2020-176391 A

In order to ensure physical distancing using a belt partition stand as described in Patent Document 1, it is necessary to mark waiting areas on the floor, as described above. Belt partition stands have the advantage that they can be combined to freely form routes, but this advantage is lost if waiting areas must be marked on the floor. In addition, if waiting areas are marked on the floor with tape, people will constantly step on the tape, which will deteriorate and require regular replacement.

In view of the above problems, one embodiment of the present invention has as its object to provide a belt partition stand that can ensure physical distancing. Another object is to provide a belt partition system that can ensure physical distancing by using multiple belt partition stands.

The partition stand according to one embodiment of the present invention includes a pole section and a head section connected to one end of the pole section and housing a belt so that the belt can be pulled out. The head section includes a sensor that detects people and an information processing section that counts the number of people detected by the sensor.

The head unit 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.

The partition system according to one 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, and 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 housing the belt so that it can be pulled out. The head portion of the first belt partition stand includes a first sensor that detects people and a first information processing unit that counts a first number of people detected by the first sensor. The head portion of the second belt partition stand includes a second sensor that detects people and a second information processing unit that counts a second number of people detected by the second sensor. The head portion of the first belt partition stand further includes a determination unit that calculates the difference between the second number and the first number.

A communication cable may be embedded in the belt to communicatively connect the first belt partition stand and the second belt partition stand.

The head portion of the first belt partition stand may further include an indicator lamp capable of lighting up multiple colors based on the difference between the second number and the first number.

The head portion of the first belt partition stand further includes a display device that displays a warning based on the difference between the second number and the first number.

The belt partition stand or belt partition system of one embodiment of the present invention can control the flow of people while maintaining physical distance.

[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 one embodiment of the present invention. Specifically, FIG. 1(A) and FIG. 1(B) are perspective views showing the same belt partition stand 10, with the viewpoints being different by approximately 90 degrees. 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 used, the base portion 100 is placed on the floor surface, and the head portion 300 is supported by the pole portion 200. It is preferable that the base portion 100 is flat so that it can be stably placed on the floor surface. The pole portion 200 is, for example, cylindrical, but is not limited to this. 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.

The belt partition stand 10 may be configured without the base portion 100. In this case, a pole insertion port is provided on the ground, and the belt partition stand 10 is used by inserting one end of the pole portion 200 into the pole insertion port.

As shown in FIG. 1, the head unit 300 includes a belt 310, a belt terminal unit 320, a connection terminal unit 330, a sensor 340, a display unit 350, and an indicator lamp 360. One end of the belt 310 is connected to the belt terminal unit 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 inside the head unit 300 and is biased to retract the belt 310 into the head unit 300, so that the belt 310 connected to the reel can be wound up. Therefore, the belt 310 can be pulled out from the head unit 300 or stored in the head unit 300 through an opening provided in the head unit 300. Note that since the width of the belt terminal unit 320 connected to the belt 310 is larger than the width of the opening, even if the belt 310 is stored in the head unit 300, the belt terminal unit 320 will not be retracted into the head unit 300.

The approximately cylindrical belt terminal portion 320 can be fitted into a cylindrical connection terminal portion 330 having a slit. In other words, two belt partition stands 10 can be connected to each other 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. The belt terminal portion 320 fits into the connection terminal portion 330 by passing the belt 310 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 pulled out from the head portion 300 is stretched between two adjacent belt partition stands 10.

A communication cable 311 is embedded within the belt 310, and the communication cable 311 may be electrically connected to a terminal disposed in the belt terminal portion 320. When the belt terminal portion 320 and the connection terminal portion 330 are engaged with each other, a terminal provided at one end of the belt terminal portion 320 and a terminal provided in 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 be communicatively connected to each other via the communication cable 311. Even when three or more belt partition stands 10 are connected to each other, they can be communicatively connected to each other.

The belt terminal portion 320 and the connection terminal portion 330 are not limited to the above-mentioned configuration. The belt terminal portion 320 and the connection terminal portion 330 may be configured in any manner that allows the terminals of the belt terminal portion 320 and the connection terminal portion 330 to come into contact with each other when connecting two belt partition stands 10. Therefore, for example, the belt terminal portion 320 and the connection terminal portion 330 can be configured to be connected by magnetic force.

In addition to the communication cable 311, 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 the other belt partition stands 10 via the power cable. In the above configuration, multiple belt partition stands 10 are shown to be connected for communication via a wired communication cable, but they may also be connected for communication wirelessly using the Internet or Wi-Fi (registered trademark), etc.

The belt partition stand 10 may be provided with a rechargeable battery unit such as a lithium ion battery. The battery unit may be housed, for example, in the internal space of the pole unit 200. By providing the battery unit, the belt partition stand 10 can operate independently. In addition, a solar panel may be incorporated in part of the pole unit 200, making it possible to charge the lithium battery.

The sensor 340 is a so-called human sensor that can detect the presence of a person. The sensor 340 can detect, for example, infrared rays equivalent to body temperature emitted 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 output a detection signal that represents the position of the person in terms of angle and distance. Therefore, the sensor 340 may be configured to not only detect infrared rays, but also to irradiate a laser or ultrasonic wave and detect the reflected wave. For example, the sensor 340 may be configured to include a laser range finder. In addition, the sensor 340 is installed on the side of the head unit 300, but a detection angle adjustment mechanism that adjusts the maximum detection range of the sensor 340 may be provided. By providing a detection angle adjustment mechanism in the head unit 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, the maximum detection range of the sensor 340 can be adjusted by providing a shielding protrusion that can limit the maximum detection range as a detection angle adjustment mechanism.

The display device 350 is a device capable of displaying an image. For example, a liquid crystal display device or an OLED (Organic Light-Emitting Diode) display device can be used as the display device 350. In addition, it is preferable that the display device 350 is provided with an input interface such as a touch panel. In addition, the display device 350 is installed on the side of the head unit 300, and it is preferable that the display direction of the display device 350 can be set by the user. As will be described in detail later, the display device 350 can not only set and check the judgment conditions based on the detection signal of the sensor 340 and the size of the physical distance between two adjacent belt partition stands 10, but can also display a warning when the physical distance is not secured.

The indicator lamp 360 is a light source such as an LED. It is preferable that the indicator lamp 360 can be lit in multiple colors, such as blue, yellow, or red, so that it is possible to visually check in stages whether or not physical distancing is being maintained. In other words, the indicator lamp 360 can visually notify information regarding physical distancing. Note that the indicator lamp 360 may not only be lit, but also be able to flash. The illumination intensity of the indicator lamp 360 can be set according to the brightness of external light. The brightness of external light can be detected by a solar panel.

Although not shown, the belt partition stand 10 may be provided with a power button or an audio output unit. Power may be supplied to the belt partition stand 10 by pressing the power button, and it is preferable that the power button is provided with a cover to prevent malfunction. The audio output unit may include, for example, a speaker that plays and outputs sound from a recorded sound source. In other words, the audio output unit can audibly notify information regarding physical distance. The sound source may be selected according to the color of the light of the indicator lamp 360.

Figure 2 is a block diagram illustrating a portion of the configuration of the head unit 300 of the belt partition stand 10 according to one embodiment of the present invention. The head unit 300 further includes a control unit 370 and a memory unit 380 that control the display device 350 and the indicator 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 microprocessor (MPU), a graphics processing unit (GPU), 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 device that can store a setting value 381 and an ID number 382 that represent the judgment condition judged by the judgment unit 372. For example, the storage unit 380 can be a hard disk drive (HDD), a solid state drive (SSD), a flash memory, or the like, but is not limited to these. The storage unit 380 may be included in a storage device.

The information processing unit 371 can set the ID number of the belt partition stand 10. The information processing unit 371 can also count the number of people detected by the sensor 340 and output the number of people N who passed in front of the belt partition stand 10. This function of the information processing unit 371 will be described in detail later.

The determination unit 372 can execute a determination using the number of passers N output by the information processing unit 371 of each of two adjacent belt partition stands 10. Specifically, the determination unit 372 calculates the difference between the number of passers N output by the information processing unit 371 of each of two adjacent belt partition stands 10, and executes a determination by comparing it with a set value 381. The determination unit 372 also generates an indication lamp control signal corresponding to the determination result, and controls the indication lamp 360. The determination conditions executed by the determination unit 372 will be described later.

The memory unit 380 can store setting values 381 and ID numbers 382 required when using the belt partition stand 10. The setting values 381 include values used for the set detection range and judgment conditions.

In the above, the control unit 370 and the memory unit 380 are provided in the head unit 300, but the control unit 370 or the memory unit 380 may be provided in the pole unit 200 or in a server on a connected network.

[2. Usage of the belt partition stand 10]
Fig. 3 is a schematic plan view for explaining a usage mode (belt partition system) of the belt partition stand 10 according to one embodiment of the present invention. In Fig. 3, two belt partition stands 10 (a first belt partition stand 10-1 and a second belt partition stand 10-2) are connected. However, the number of connected belt partition stands 10 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).

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 engaged with 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 from the first belt partition stand 10-1 to the second belt partition stand 10-2.

When the first belt partition stand 10-1 and the second belt partition stand 10-2 are connected and the power supply of each of the first belt partition stand 10-1 and the second belt partition stand 10-2 is turned on, the ID numbers of the first belt partition stand 10-1 and the second belt partition stand 10-2 are set through the second communication cable 311-2 embedded in the second belt 310-2. The ID numbers 382 are assigned in the order in which the belt partition stands 10 are connected and stored in the memory unit 380. By assigning the ID number 382 to each belt partition stand 10, it becomes possible to set the detection conditions of the sensor 340 and the size of the physical distance (distance per person) d for each belt partition stand 10. These setting values 381 are also stored in the memory unit 380. In the following, the quotient of L/d is assumed to be 3. The quotient of L/d corresponds to the number of people that can be accommodated between the first belt partition stand 10-1 and the second belt partition stand 10-2. Therefore, for the sake of convenience, the following explanation will refer to the quotient of L/d as the number of people that can be accommodated, M.

The first sensor 340-1 of the first belt partition stand 10-1 detects people passing in front of the first belt partition stand 10-1. As shown in FIG. 3, four people, a first person 500-1 to a fourth person 500-4, pass 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 people detected by the first sensor 340-1 and sets the first number of passers N(1) of the first belt partition stand 10-1 to 4.

The second sensor 340-2 of the second belt partition stand 10-2 detects people passing in front of the second belt partition stand 10-2. As shown in FIG. 3, one of the first people 500-1 passes 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 people detected by the second sensor 340-2 and sets the second number of people passing through the second belt partition stand 10-2, N(2), to 1.

The first judgment unit 372-1 of the first belt partition stand 10-1 receives the second number of passers N(2) via the second communication cable 311-2 of the second belt partition stand 10-2.

The first judgment 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 in the span S. That is, S=N(1)-N(2)=3 is obtained, and it is found that there are three people in the span L between the first belt partition stand 10-1 and the second belt partition stand 10-2. The first judgment unit 372-1 compares the allowable number of people M with the number of people in the span S, and transmits a display lamp control signal to the first indicator lamp 360-1 according to a predetermined judgment condition. Here, since the allowable number of people M and the number of people in the span S are the same value, the first judgment unit 372-1 transmits a display lamp control signal that causes the first indicator lamp 360-1 to light up in red. A fifth person 500-5 who is trying to pass through the first belt partition stand 10-1 sees that the first indicator lamp 360-1 is lit red and can visually understand that he or she cannot pass through the first belt partition stand 10-1.

When the difference (M-S) between the allowable number of people M and the number of people in the span S is 1, the first judgment unit 372-1 transmits an indicator lamp control signal to turn on the first indicator lamp 360-1 in yellow to alert people passing in front of the first belt partition stand 10-1. When the difference between the allowable number of people M and the number of people in the span S is greater than 1, the first judgment unit 372-1 transmits an indicator lamp control signal to turn on the first indicator lamp 360-1 in blue to allow people to pass in front of the first belt partition stand 10-1. In this way, a person 500 who is about to pass in front of the first belt partition stand 10-1 can check the color of the first indicator lamp 360-1 and determine whether or not it is OK to pass in front of the first belt partition stand 10-1.

In addition, when the number of people S in the span is greater than the allowable number of people M, the first judgment unit 372-1 transmits an indicator lamp control signal to cause the first indicator lamp 360-1 to flash in red. As a result, a person 500 who has passed the first belt partition stand 10-1 can see that the first indicator lamp 360-1 is flashing in red, 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 for a moment. At this time, a warning such as "The maximum number of people has been exceeded. Please stop for a moment to ensure physical distance" may be displayed on the first display device 350-1. In addition, if an audio output unit is provided in the first belt partition stand 10-1, an alarm may be issued from the audio output unit. In addition, the second indicator lamp 350-2 of the second belt partition stand 10-2 may be flashed in blue to prompt a person 500 who is about to pass the second belt partition stand 10-2 to move forward.

In the above, a belt partition system using two belt partition stands 10 has been described as an example, but the judgment conditions for the allowable number of people M(n-1) for the number of people S(n-1) (i.e., N(n-1)-N(n)) in the n-1 span between the n-1 belt partition stand 10-n-1 and the n belt partition stand 10-n in n belt partition stands 10 (n is an integer of 2 or more) and the lighting color of the n-1 display lamp 360-n-1 are, for example, as shown in Table 1. A person 500 about to pass in front of the n-1 belt partition stand 10-n-1 can check the n-1 display lamp 360-n-1 of the n-1 belt partition stand 10-n-1 and decide whether to move forward or not. However, the judgment conditions and lighting colors are not limited to those in Table 1.

In addition, in the case of a belt partition system using three or more (i.e., n≧3) belt partition stands 10, the judgment can also be made using the number of people in two adjacent spans L. For example, the judgment conditions in the n-1th judgment unit 372-n-1 of the n-1th belt partition stand 10-n-1 located between two adjacent spans L and the lighting color of the n-1th display lamp 360-n-1 are, for example, as shown in Table 2. However, the judgment conditions and lighting colors are not limited to those in Table 2.

In the judgment conditions shown in Table 2, the n-1st indicator lamp 360-n-1 is controlled to not only be lit in blue but also to flash in blue. In this case, not only the number of people S(n-1) in the n-1st span but also the number of people S(n-1) in the n-2th span where the person 500 who is about to pass through the n-1st belt partition stand 10-n-1 is present may be taken into consideration. That is, when the number of people S(n-2) in the n-2th span (i.e., N(n-2)-N(n-1)) satisfies S(n-2)<M(n-2)-1, there is sufficient space in the n-2th span L(n-2), so physical distance can be ensured. Therefore, the n-1st indicator lamp 360-n-1 is lit in blue, and the person 500 can proceed forward as usual. However, when the number of people S(n-2) in the n-2th span satisfies S(n-2) ≧ M(n-2)-1, there is not enough space in the n-2th span L(n-2), making it difficult to maintain physical distance. Therefore, the n-1th indicator lamp 360-n-1 flashes blue, urging the person 500 to move forward.

Now, with reference to Figures 4 and 5, we will explain the person counting process (the process of generating the number of passers N) executed by the control unit 370 (specifically, the information processing unit 371).

FIG. 4 is a schematic diagram illustrating the detection signal and set detection range of the sensor 340 of the belt partition stand 10 according to one embodiment of the present invention. As shown in FIG. 4(A), the sensor 340 can output a detection signal that indicates the position of a person as a detection angle θ (°) and a distance r (m). Also, as shown in FIG. 4(B), the sensor 340 has a maximum detection range, which is an angle ±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 an angle ±β (°) (β<α) and a distance l _b (m) (l _b <l _dm ). In this way, by setting the set detection range of the sensor 340, counting processing while tracking a person is possible.

Figure 5 is a flow chart diagram of the process of counting people detected by the sensor 340 executed by the control unit 370 of the belt partition stand 10 according to one embodiment of the present invention. The counting process is started when a person is detected by the sensor 340.

In step S110, it is determined whether or not the person 500 is present within the set detection range of the sensor 340. That is, the information processing unit 371 determines whether or not the detection angle θ ₁ (°) of the person 500 at the first time (t ₁ ) satisfies −β≦θ ₁ ≦+β, and the distance r ₁ (m) of the person 500 at t ₁ satisfies r ₁ ≦l _b . If the person 500 is present within the set detection range of the sensor 340 (step S110: YES), step S120 is executed. Also, if the person 500 is not present within the set detection range of the sensor 340 (step S110: NO), step S110 is executed again.

In step S120, after a predetermined time has elapsed, it is determined whether the person 500 is moving in the direction of travel. That is, the information processing unit 371 calculates the moving distance D 2 =r ₂ sin θ ₂ -r 1 sin θ 1 of the person 500 from t ₁ to t ₂ from the detected angle θ ₂ (°) and distance r ₂ (m) of the person 500 at the second time (t ₂ ) and the detected angle θ _{1 ( ° )} and distance r ₁ (m) of the person 500 at t ₁ , and determines whether D ₂ satisfies D ₂ >F _d (any positive value). If the person 500 is moving in the direction of travel (step S120: YES), step S130 is executed. Also, if the person 500 is not moving in the direction of travel (step S120: NO), there is a possibility that the person 500 is moving in the opposite direction to the direction of travel, so step S120 is executed again.

In step S130, the number of people detected by the sensor 340 (the number of people passing through the belt partition stand 10) is accumulated. That is, the information processing unit 371 adds 1 to the number of people passing through N and sets the value as the new number of people passing through N. Note that immediately after the power to the belt partition stand 10 is turned on, N = 0 because no people have been detected by the sensor 340.

In step S140, after a predetermined time has elapsed, it is determined whether or not 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 θ ₃ (°) of the person 500 at the third time (t ₃ ) satisfies θ ₃ > +β. If the person 500 is outside the set detection range in the traveling direction (step S140: YES), the person counting process is terminated. Also, if the person 500 is not outside the set detection range in the traveling direction (step S140: NO), the person 500 may have stopped temporarily or may be moving in the opposite direction to the traveling direction, so step S150 is executed.

In step S150, it is determined whether the person 500 is moving in the opposite direction to the moving direction. That is, the information processing unit 371 calculates the moving distance D 3 =r 3 sin θ ₃ -r 2 sin θ 2 of the person 500 from t ₂ to t ₃ from the detected angle θ ₃ (°) and distance r ₃ (m) of the person 500 at t ₃ and the detected angle _{θ 2} ( _{°) and} distance r ₂ (m) of the person 500 at _{t 2} , and determines whether D ₃ satisfies D ₃ <B _d (any negative value). If the person 500 is moving in the opposite direction to the moving direction (step S150: YES), step S160 is executed. Also, if the person 500 is not moving in the opposite direction to the moving direction (step S150: NO), since there is a possibility that the person 500 has stopped temporarily, step S140 is executed again.

In step S160, it is determined whether or not the person 500 is outside the set detection range. That is, the information processing unit 371 determines whether or not the detection angle θ ₃ (°) of the person 500 at t ₃ satisfies θ ₃ < -β, or whether or not the detection distance r ₃ (m) of the person 500 satisfies r ₃ > 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.

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 subtracts 1 from the number of people passing N and sets the result as the new number of people passing N. A person 500 who moves in the opposite direction to the forward direction in step S150 and is outside the set detection range of the sensor 340 in step S160 is considered to have returned without moving in the forward direction. Therefore, step S170 is executed to reset the number of people passing N accumulated in step S130 to the original value.

As described above, the belt partition stand 10 according to one embodiment of the present invention can detect people passing by using the sensor 340, and can count the number of people passing through the belt partition stand 10 by using the control unit 370 (specifically, the information processing unit 371) while tracking the people. Furthermore, a belt partition system using multiple 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 encourage physical distancing.

Embodiments of the present invention can be implemented by combining appropriate configurations as long as they are not mutually contradictory. Furthermore, those in which a person skilled in the art has appropriately added or deleted configurations or modified designs based on the embodiments, or added or omitted processes or changed conditions, are also included in the scope of the present invention as long as they contain the gist of the present invention.
