Description

[Technical field]

[0001] The present invention relates to a circuit breaker that can efficiently regulate or deregulate access at multiple locations in a facility. [Background technology]

[0002] Conventionally, belt partitions have been used as a means for regulating and guiding the passage of users in facilities (see, for example, Patent Document 1). In the belt partition, a belt storage head is disposed at the upper end of a support pillar that is vertically erected on a base. In this belt storage head, a belt is stored, wound around a reel, in a state in which the belt can be unwound and biased in the winding direction by a biasing means.

[0003] When using a belt partition, the belt is unwound and the belt end at the tip of the belt is engaged with the belt end receiving part of another belt partition. A facility manager (e.g., a resident security guard) arranges multiple belt partitions at appropriate intervals in an area of ​​the facility where the passage of users is restricted or guided, and constructs a restriction zone (partition) by manually unwound one of the belts of an adjacent belt partition and engaging the belt end with the belt end receiving part of the other.

[0004] Also, instead of a belt partition, a shutter device is known that automatically lowers or raises a shutter curtain from the ceiling to restrict or release passage on an escalator (for example, Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6336746 [Patent Document 2] JP 2010-7396 A Summary of the Invention [Problem to be solved by the invention]

[0006] Here, in the case of a belt partition as disclosed in Patent Document 1, for example, in a large store where business hours differ depending on the floor, when multiple escalators and stairs leading to upper floors that close earlier are to be restricted at the closing time, the number of facility managers corresponding to the number of places where the restriction is required must share the work of setting up the restriction belts using the partitions at each place. Not only in this case, but in the past, in order to restrict traffic at multiple places in a facility at the same time or to lift the restriction, the number of facility managers corresponding to the number of places must be secured, which was inefficient.

[0007] Furthermore, the shutter device disclosed in Patent Document 2 is expensive to introduce, and is subject to the constraint that installation space must be secured in the ceiling.

[0023] [Embodiment 1] The circuit breaker according to the present embodiment 1 will be described in detail below with reference to the drawings. In the present embodiment 1, a case will be described in which an automatic opening / closing belt partition (corresponding to the "circuit breaker" according to the present invention) is installed in various facilities such as department stores and commercial facilities (hereinafter collectively referred to as "facilities").

[0024] <Outline of the Automatic Opening and Closing Belt Partition 100> 1 is an explanatory diagram for explaining an overview of the automatic opening / closing belt partition 100 according to the present embodiment 1. Here, the belt payout device 110 is provided with a wireless communication receiving unit, and is capable of receiving blocking unit extension instruction data (hereinafter referred to as a "blocking unit extension instruction") or blocking unit contraction instruction data (hereinafter referred to as a "blocking unit contraction instruction") from the remote control terminal 200.

[0025] As shown in FIG. 1, the automatic opening / closing belt partition 100 stores a belt portion 111 in a belt unwinding device 110 attached to the top of a support 120. The belt portion 111 is an example of a blocking portion in the present invention. The unwinding of the belt portion 111 from the belt unwinding device 110 corresponds to the extension of the blocking portion in the present invention, and the storage of the belt portion 111 in the belt unwinding device 110 corresponds to the contraction of the blocking portion in the present invention. The automatic opening / closing partition 100 is installed in a facility, and the passage of users of the facility is restricted by setting the belt portion 111 in a unwinding state, and the restriction is lifted by setting it in a stored state. Here, the entire belt portion 111 is not stored in the belt unwinding device 110, but a part of it protrudes from the belt unwinding device 110. The reason for this will be described later.

[0026] When the belt portion 111 is stored in the belt unwinding device 110, if the remote control terminal 200 receives a predetermined blocking portion extension operation (e.g., pressing an extension button) by an operator such as a security guard (hereinafter referred to as the "operator"), the remote control terminal 200 transmits a blocking portion extension instruction to the belt unwinding device 110 (S1). Upon receiving the blocking portion extension instruction, the belt unwinding device 110 unwinds the belt portion 111 from the belt unwinding device 110 (S2). This makes it possible to regulate the passage of users of the facility.

[0027] Furthermore, if the remote control terminal 200 receives a predetermined blocking unit contraction operation (e.g., pressing a contraction button) by the operator while the belt portion 111 is being paid out from the belt reeling device 110, the remote control terminal 200 transmits a blocking unit contraction instruction to the belt reeling device 110 (S3). Upon receiving the blocking unit contraction instruction, the belt reeling device 110 stores the belt portion 111 in the belt reeling device 110 (S4). This allows the restriction on access to the facility for users to be lifted.

[0028] In this way, the automatic opening / closing belt partition 100 of this embodiment 1 is configured to control the extension or retraction of the belt portion 111 of the automatic opening / closing belt partition 100 by operating the remote control terminal 200 carried by the operator. Therefore, even if the operator is located away from the automatic opening / closing belt partitions 100 installed at multiple locations in the facility, the operator can remotely control the extension or retraction of the belt portion 111 of the automatic opening / closing belt partition 100 using the remote control terminal 200 carried by the operator, and traffic restrictions or lifting restrictions can be efficiently implemented at multiple locations in the facility.

[0029] <System configuration of automatic opening / closing belt partition system> Next, a description will be given of the system configuration of the automatic opening / closing belt partition system according to the embodiment 1. Fig. 2 is a diagram showing the system configuration of the automatic opening / closing belt partition system according to the embodiment 1.

[0030] 2, multiple automatic opening / closing belt partitions such as automatic opening / closing belt partitions 100a, 100b (hereinafter collectively referred to as "automatic opening / closing belt partitions 100") are installed in the facility to restrict or unrestrict the passage of users. The multiple automatic opening / closing belt partitions 100 are capable of communicating with the transceiver 300 via wireless communication.

[0031] The transceiver 300 can communicate with the remote control terminal 200 by wireless communication. This remote control terminal 200 can communicate with the automatic opening / closing belt partition 100 via the transceiver 300, and transmits a blocking section extension instruction or a blocking section contraction instruction received from the remote control terminal 200 to the automatic opening / closing belt partition 100.

[0032] Any communication standard may be used for the wireless communication between the automatic opening / closing belt partition 100 and the transceiver 300, and for the wireless communication between the transceiver 300 and the remote control terminal 200. Depending on the communication distance required for each wireless communication, the most appropriate one may be selected from among well-known wireless communication technologies, such as short-range wireless communication such as Bluetooth (registered trademark), Wi-Fi (registered trademark), UWB (Ultra-Wide Band), and the fifth generation mobile communication system.

[0033] <Configuration of the automatic opening / closing belt partition 100> Next, a description will be given of the configuration of the automatic opening / closing belt partition 100. Fig. 3 is a functional block diagram showing the configuration of the automatic opening / closing belt partition 100 shown in Fig. 2. As shown in Fig. 3, the automatic opening / closing belt partition 100 has a belt reeling device 110, a support 120, and a base 130.

[0034] The belt reeling device 110 is a device that controls the reeling and storage of the belt portion 111, and has the belt portion 111, a storage portion 112, a drive portion 113, a communication portion 114, a control portion 115, a battery 116, and a rotary encoder 117.

[0035] The belt section 111 is a tape measure type aluminum tape, which is fed and stored by the drive section 113. When the aluminum tape of the belt section 111 is fed with the tape surface horizontal, it will bend downward due to gravity, so to prevent this, the aluminum tape is fed in a direction in which the tape surface of the aluminum tape is perpendicular to the ground. In addition, by making the shape of the feeding outlet slightly upward, when the aluminum tape is stretched, it will bend gently downward from the vicinity of the feeding outlet to the tip due to its own weight, so that the overall shape is almost horizontal. In addition, the exposed part of the aluminum tape is wrapped in a brightly colored cylindrical cloth (not shown) to prevent injury accidents due to contact with the user and to increase visibility from the outside.

[0036] The storage section 112 is a cylindrical empty chamber that stores the belt section 111. The drive section 113 is a drive device for paying out and storing the belt section 111. The drive section 113 pays out the belt section 111 when it receives a payout instruction from the control section 115, and stores the belt section 111 when it receives a storage instruction.

[0037] The communication unit 114 is an interface unit for performing wireless communication with the transceiver 300 and receiving a cutoff unit extension instruction or a cutoff unit contraction instruction. The battery 116 is a power supply unit for supplying power to the drive unit 113, the communication unit 114, the control unit 115, and the rotary encoder 117.

[0038] The control unit 115 is a control unit that performs overall control of the belt payout device 110, and has a belt portion payout control unit 115a and a belt portion storage control unit 115b. In practice, these programs are loaded into a CPU (Central Processing Unit) and executed, causing the belt portion payout control unit 115a and the belt portion storage control unit 115b to execute the processes corresponding thereto.

[0039] The belt portion payout control unit 115a is a processing unit that controls the payout of the belt portion 111. When the belt portion payout control unit 115a receives a blocking portion extension instruction via the communication unit 114, it transfers the payout instruction to the drive unit 113.

[0040] The belt portion storage control unit 115b is a processing unit that controls the storage of the belt portion 111. When the belt portion storage control unit 115b receives a blocking portion contraction instruction via the communication unit 114, it transfers the storage instruction to the drive unit 113.

[0041] As described above, the exposed portion of the aluminum tape of the belt portion 111 is wrapped in a cylindrical cloth or the like, so that when stored, a part of the tip of the belt portion 111 protrudes from the belt delivery device 110.

[0042] The support pillar 120 is a rod-shaped pillar that supports the belt reeling device 110. The base 130 is a disk-shaped or square plate that supports the support pillar 120.

[0043] The rotary encoder 117 is a measuring device that acquires the amount of rotation of a roller that rotates in conjunction with the payout and retraction movement of the belt portion 111, and transmits the acquired amount of rotation to the control portion 115. Details will be described later.

[0044] <External configuration of the belt portion according to the first embodiment> Next, there will be described an external configuration of a portion related to the belt part according to the present embodiment 1. Fig. 4 is a diagram showing an external configuration of a portion related to the belt part according to the present embodiment 1.

[0045] Belt portion 111 is composed of two aluminum tapes. The free ends of the two aluminum tapes are screwed together and connected to each other. Inside belt payout device 110, there are two storage sections 112a and 112b arranged opposite each other to store belt portion 111, and belt portion 111 is stored in each storage section 112 in the shape of a tape measure.

[0046] The belt unit 111 is sandwiched between a roller of the drive unit 113 and a roller of a rotary encoder 117 disposed opposite to the belt unit 111, and is extended and retracted by the power of the drive unit 113. The drive unit 113 can also change the speed of extension and retraction by changing the rotation speed.

[0047] An iron bar is placed at the center of the tape measure of belt part 111 stored in storage part 112, and this iron bar is fixed to storage part 112. The center of the spiral spring of the tape measure is attached to the iron bar, and generates a rewinding force when the aluminum tape is pulled out from the tape measure. The rewinding force of the spiral spring makes it possible to wind the aluminum tape in a state where it is tightly attached to the cylindrical drum of the tape measure when rewinding it.

[0048] Rotary encoder 117 is capable of acquiring the amount of rotation of the roller, and is able to acquire the length of the aluminum tape of belt portion 111 that has been unwound based on this amount of rotation. The amount of rotation acquired by rotary encoder 117 is transmitted to control unit 115. When control unit 115 detects that the unwound length has reached a predetermined value based on the amount of rotation received from rotary encoder 117, it stops driving unit 113 to stop the unwounding of belt portion 111.

[0049] The aluminum tape portion of the belt portion 111 is tape-measure shaped, so it can be unwound to a specified position without buckling. This aluminum tape portion can also be wrapped in a stretchable cylindrical cloth or the like to prevent people nearby from coming into contact with it and getting injured.

[0050] <An example of using the automatic opening and closing belt partition 100> Next, a description will be given of an example of how the automatic opening / closing belt partition 100 according to the first embodiment is used. Fig. 5 is a diagram showing an example of how the automatic opening / closing belt partition 100 according to the first embodiment is used.

[0051] As shown in Fig. 5, the automatic opening / closing belt partition 100 is installed near the entrance and exit of an escalator E to restrict the use of the escalator. For example, when the floor on which the automatic opening / closing belt partition 100 is installed is open during business hours, but the floor above is closed, the belt portion 111 of the automatic opening / closing belt partition 100 is extended to restrict the movement of users to the upper floor.

[0052] <Control procedure for the belt part of the automatic opening / closing belt partition 100> Next, there will be described a control procedure for the belt portion of the automatic opening / closing belt partition 100 according to the present embodiment 1. Fig. 6 is a flowchart showing a control procedure for the belt portion of the automatic opening / closing belt partition 100 according to the present embodiment 1.

[0053] 6, the belt unwinding device 110 is in a state of waiting to receive a blocking unit contraction instruction or a belt unit unwinding instruction from the remote control terminal 200 that has received an instruction from an operator to extend or contract the blocking unit during preparation for opening or closing the facility (step S101; No, step S103; No). If a blocking unit contraction instruction is received during this waiting state (step S101; Yes), the belt unit 111 is stored (step S102) and the process ends.

[0054] On the other hand, if the belt reeling device 110 receives a blocking portion extension instruction from the remote control terminal 200 (step S103; Yes), it reels out the belt portion 111 (step S104) and ends the process.

[0055] As described above, the automatic opening / closing belt partition of this embodiment 1 is configured so that the extension or retraction control of the belt portion of the automatic opening / closing belt partition 100 is performed by operating the remote control terminal 200 carried by an operator, thereby making it possible to efficiently restrict or release passage at multiple locations in the facility.

[0056] In the above-mentioned first embodiment, the case where the automatic opening / closing belt partition 100 is controlled via the transceiver 300 by operating the remote control terminal 200 carried by the operator has been described, but the present invention is not limited to this. It is also possible to configure the belt payout device 110 to control the automatic opening / closing belt partition 100 from a remote terminal device connected to the Internet at a remote location via a Wi-Fi (registered trademark) router connected to the Internet.

[0057] [Variation 1] Incidentally, in the above-mentioned first embodiment, a case has been described in which the automatic opening / closing belt partition 100 is controlled by operating the remote control terminal 200 carried by the operator, but the present invention is not limited to this. The automatic opening / closing belt partition 100 can also be configured to be controlled in cooperation with a monitoring terminal that monitors the situation in the vicinity of the installation location of the automatic opening / closing belt partition 100. In this first modified example, an automatic opening / closing belt partition system that controls the automatic opening / closing belt partition 100 in cooperation with a monitoring device that monitors the situation in the vicinity of the installation location of the automatic opening / closing belt partition 100 will be described.

[0058] <System configuration of automatic opening / closing belt partition system according to modification 1> A description will be given of the system configuration of the automatic opening / closing belt partition system according to the present modified example 1. Fig. 7 is a diagram showing the system configuration of the automatic opening / closing belt partition system according to the present modified example 1.

[0059] 7, the automatic opening / closing belt partition system according to the present modified example 1 includes a surveillance camera 400, a display device 410, a surveillance terminal 420, a transceiver 300, and a plurality of automatic opening / closing belt partitions 100. The surveillance camera 400 is communicatively connected to the display device 410. The surveillance terminal 420 is communicatively connected to the belt payout devices 110 of the plurality of automatic opening / closing belt partitions 100 via the transceiver 300.

[0060] The surveillance camera 400 is installed in a position where it can capture the situation around the installation location of the automatic opening / closing belt partition 100, and transmits the captured image to the display device 410. The display device 410 displays the image received from the surveillance camera 400.

[0061] When the monitoring terminal 420 receives an operation from the operator to instruct the blocking unit to be extended or to be retracted, the monitoring terminal 420 transmits a blocking unit extension instruction or a blocking unit retraction instruction to the belt unwinding device 110 via the transceiver 300. When the belt unwinding device 110 receives the blocking unit extension instruction or the blocking unit retraction instruction, the belt unwinding device 110 controls the belt unit 111 based on the received instruction.

[0062] The operator checks the situation near the location where the automatic opening / closing belt partition 100 is installed by using the image displayed on the display device 410, and controls the belt portion 111 of the automatic opening / closing belt partition 100 using the monitoring terminal 420 based on the level of congestion among users at the facility, etc.

[0063] <An example of use of the automatic opening / closing belt partition 100 according to the first modified example> Next, a description will be given of an example of how the automatic opening / closing belt partition 100 according to the present modified example 1 is used. Fig. 8 is a diagram showing an example of how the automatic opening / closing belt partition 100 according to the present modified example 1 is used.

[0064] Figure 8 illustrates a case in which an existing belt partition, in which the belt section is manually extended and retracted, and an automatic opening / closing belt partition 100 are used in front of the facility entrance to dynamically set a guide route for facility users to the entrance and regulate the queues of facility users waiting to enter.

[0065] 8(a), when the operator confirms on the display device 410 that the queue of users waiting to enter a facility (not shown) is not long, the monitor terminal 420 is used to control the belt parts 111 of the automatic opening / closing belt partitions 100a and 100b to an extended state, and the belt part 111 of the automatic opening / closing belt partition 100c to a stored state. This shortens the distance users have to travel to the entrance, facilitating smooth entry.

[0066] 8(b), when an operator confirms on the display device 410 that the queue of users waiting to enter a facility (not shown) is long, the operator uses the monitoring terminal 420 to control the belt parts 111 of the automatic opening / closing belt partitions 100a and 100b to a stored state and the belt part 111 of the automatic opening / closing belt partition 100c to an extended state. This lengthens the distance users must travel to the entrance, preventing confusion caused by an extended queue.

[0067] As described above, the automatic opening / closing belt partition system according to the present modified example 1 is configured to control the automatic opening / closing belt partition 100 in cooperation with the monitoring terminal 420 that monitors the automatic opening / closing belt partition 100, so that it is possible to efficiently restrict or lift restrictions on passage at multiple locations in a facility. Also, when restricting the entry queue of users of a facility using an existing belt partition and the automatic opening / closing belt partition 100 in which the belt portion is manually extended and retracted, it is possible to dynamically change the guide route and distance to the destination according to the congestion situation.

[0068] [Variation 2] Incidentally, in the above-mentioned embodiment 1, a configuration in which the breaker part of the present invention is expanded and contracted by feeding and storing a belt part made of aluminum tape has been described, but the present invention is not limited to this. It is also possible to configure the breaker part to expand and contract using a tare-shaped breaker part instead of an aluminum tape. The tare-shaped breaker part restricts the passage of users by inflating it with air to an expanded state, and releases the restriction by releasing the air to a contracted state. In this modification 2, a breaker that expands and contracts using a tare-shaped breaker part will be described.

[0069] <Configuration of circuit breaker 500> A description will be given of the configuration of the circuit breaker 500 according to the present modified example 2. Fig. 9 is a functional block diagram showing the configuration of the circuit breaker 500 according to the present modified example 2. Note that a description of the functional parts similar to those of the automatic opening / closing belt partition 100 shown in Fig. 3 will be omitted.

[0070] As shown in FIG. 9, the circuit breaker 500 includes a circuit breaker extension 510, a support post 120, and a base 130.

[0071] The cutoff section extension section 510 is a device that controls the extension and contraction of the cutoff section 511, and has the cutoff section 511, a storage section 512, a drive section 513, a communication section 114, a control section 515, and a battery .

[0072] The blocking section 511 is a container made of a cylinder made of a flexible material with one of two openings sealed, and the storage section 512 is an air chamber that is connected to the blocking section 511, which is a container, to form an integrated air chamber. By feeding air into the storage section 512 and the blocking section 511 by the driving section 513, the blocking section 511, which is a container, expands and extends into a rod shape, and by exhausting the air inside the storage section 512 and the blocking section 511 by the driving section 513, the blocking section 511, which is a container, contracts and is stored in the storage section 512. The driving section 513 is a device that supplies and exhausts air to and from the storage section 512 and the blocking section 511 in order to expand and contract the blocking section 511, and is provided with a check valve to prevent the supplied air from flowing back, and an exhaust valve to exhaust air from the storage section 512 and the blocking section 511. The exhaust valve is normally closed, but opens under external control. When the drive unit 513 receives an air supply command from the control unit 515, it supplies air to the blocking unit 511 for a certain period of time to bring the blocking unit 511 into an extended state. When the drive unit 513 receives an exhaust command from the control unit 515, it controls to open an exhaust valve to exhaust air from the blocking unit 511 and bring the blocking unit 511 into a contracted state.

[0073] The control unit 515 is a control unit that performs overall control of the blocking unit extension unit 510, and has an air supply control unit 515a and an exhaust control unit 515b. In practice, the programs of the air supply control unit 515a and the exhaust control unit 515b are loaded into the CPU and executed, thereby causing the processes corresponding to the air supply control unit 515a and the exhaust control unit 515b to be executed.

[0074] The air supply control unit 515a is a processing unit that controls the extension of the blocking unit 511. The exhaust control unit 515b is a processing unit that controls the contraction of the blocking unit 511. When the air supply control unit 515a receives a blocking unit extension instruction from the remote control terminal 200 (not shown) via the communication unit 114, the air supply control unit 515a transfers the air supply instruction to the drive unit 513. When the exhaust control unit 515b receives a blocking unit contraction instruction from the remote control terminal 200 (not shown) via the communication unit 114, the exhaust control unit 515b transfers the exhaust instruction to the drive unit 513.

[0075] As described above, the circuit breaker 500 of this second variant is configured to extend and contract using the tare-shaped circuit breaker section 511, so that access restrictions or lifting restrictions can be efficiently carried out at multiple locations in the facility.

[0076] In the above embodiment 1, a case where the aluminum tape wrapped in a cylindrical cloth or the like is used for extension and retraction is described, and in the above modification 2, a case where a rod-shaped container is used for extension and contraction is described, but the present invention is not limited to this. Instead of a cylindrical cloth or container, a hanging cloth like a curtain can be hung on the aluminum tape for extension and retraction. This hanging cloth can also be configured to be stored in a support pole when stored.

[0077] [Variation 3] Incidentally, in the above-mentioned embodiment 1, a case has been described in which the belt portion of the belt unwinding device is controlled by operating a remote control terminal carried by an operator, but the present invention is not limited to this. The belt portion can also be configured to be controlled by operating an operation button provided on the belt unwinding device. In this modification 3, a belt unwinding device in which the belt portion is controlled by operating an operation button provided on the belt unwinding device will be described.

[0078] <External Configuration of Belt Payout Device 150> A description will be given of the external configuration of the belt unwinding device 150 according to the present modified example 3. Fig. 10 is a diagram showing the external configuration of the belt unwinding device 150 according to the present modified example 3.

[0079] As shown in FIG. 10, the belt payout device 150 is provided on its upper surface with a payout reservation button 151 for the belt unit 111, a storage reservation button 152, and a display unit 153. For example, when the payout reservation button 151 is pressed, the belt unit 111 is paid out after a predetermined time (e.g., 10 minutes) has elapsed. On the other hand, when the storage reservation button 152 is pressed, the belt unit 111 is stored after a predetermined time (e.g., 6 hours) has elapsed. The display unit 153 displays the time remaining until the payout start time or the storage start time of the belt unit 111. The predetermined time can also be set by an input unit or a remote control terminal (not shown). The predetermined time may be configured to be arbitrarily changed in response to the operation of the payout reservation button 151 or the storage reservation button 152.

[0080] As described above, the belt payout device 150 of this third variant is configured to control the payout or storage of the belt section 111 after a predetermined time has elapsed by operating the payout reservation button 151 or the storage reservation button 152, so that traffic restrictions or lifting restrictions can be efficiently implemented at multiple locations in the facility.

[0081] [Embodiment 2] Incidentally, in the above-mentioned embodiment 1, a configuration has been described in which the belt portion 111 of the belt payout device 110 is controlled by operating the remote control terminal 200 carried by the operator, but the present invention is not limited to this. It is also possible to configure so that a schedule for controlling the belt portion 111 is registered in a server device, and the belt portion 111 is controlled based on this schedule. In the present embodiment 2, an automatic opening / closing belt partition system will be described in which a schedule for controlling the belt portion 111 is registered in a server device, and the belt portion 111 is controlled based on this schedule.

[0082] <System configuration of the automatic opening / closing belt partition system according to the second embodiment> A description will be given of the system configuration of the automatic opening / closing belt partition system according to the embodiment 2. Fig. 11 is a diagram showing the system configuration of the automatic opening / closing belt partition system according to the embodiment 2.

[0083] In order to regulate the passage of users, a plurality of automatic opening / closing belt partitions 100 (for example, automatic opening / closing belt partitions 100a, 100b, etc.) are installed in the facility. The plurality of automatic opening / closing belt partitions 100 are capable of communicating with the transceiver 300 via wireless communication.

[0084] The server device 600 is communicatively connected to the automatic opening / closing belt partition 100 via the transceiver 300. The server device 600 transmits a blocking section extension command or a blocking section contraction command to the automatic opening / closing belt partition 100 based on a schedule stored in advance.

[0085] <Configuration of Server Device 600> Next, a description will be given of the configuration of the server device 600 shown in Fig. 11. Fig. 12 is a functional block diagram showing the configuration of the server device 600 shown in Fig. 11. As shown in Fig. 12, the server device 600 is connected to a display unit 601 and an input unit 602, and has a communication unit 604, a storage unit 605, and a control unit 606.

[0086] The display unit 601 is a display device such as a liquid crystal panel, a display device, etc. The input unit 602 is an input device such as a keyboard, a mouse, etc. The communication unit 604 is an interface unit for data communication with the transceiver 300.

[0087] The storage unit 605 is a storage device such as a hard disk drive or a non-volatile memory, and stores schedule data 605a. The schedule data 605a is data indicating a control schedule for the belt unit 111 of the automatic opening / closing belt partition 100.

[0088] The control unit 606 is a control unit that performs overall control of the server device 600, and includes a schedule management unit 606a and a belt unit control unit 606b. In practice, these programs are loaded into a CPU and executed, causing the schedule management unit 606a and the belt unit control unit 606b to execute the processes corresponding thereto.

[0089] The schedule management unit 606a is a processing unit that manages the schedule data 605a. When the schedule management unit 606a receives schedule data related to the control of the belt unit 111 of the automatic opening / closing belt partition 100 from the input unit 602, the schedule management unit 606a stores the schedule data in the schedule data 605a.

[0090] The belt section control unit 606b is a processing unit that controls the belt section 111 of the automatic opening / closing belt partition 100 based on the schedule data 605a. When the time stored in the schedule data 605a arrives, the belt section control unit 606b extracts the target device ID and control category corresponding to this data, and transmits an instruction indicated by the control category to the belt payout device 110 of the extracted target device ID.

[0091] Next, a description will be given of an example of data stored in the storage unit 605 of the server device 600 shown in Fig. 12. Fig. 13 is a diagram showing an example of the schedule data 605a shown in Fig. 12.

[0092] The schedule data 605a shown in FIG. 13 associates a state in which the control category is "contraction" and the target device ID is "belt partition 01" with the time "7:00", a state in which the control category is "contraction" and the target device ID is "belt partition 02" with the time "8:00", a state in which the control category is "contraction" and the target device ID is "belt partition 02" with the time "17:00", and a state in which the control category is "extension" and the target device ID is "belt partition 01" with the time "18:00".

[0093] Based on the schedule data 605a shown in Figure 13, when the time becomes, for example, "7:00", the belt section control unit 606b extracts the target device ID "belt partition 01" and control category "contraction" corresponding to this data, and sends a blocking section contraction instruction corresponding to the control category "contraction" to the belt unwinding device 110 of the extracted target device ID, and when the time becomes "17:00", it extracts the target device ID "belt partition 02" and control category "extension" corresponding to this data, and sends a blocking section extension instruction corresponding to the control category "extension" to the belt unwinding device 110 of the extracted target device ID.

[0094] As described above, in the automatic opening / closing belt partition system of this embodiment 2, a schedule for controlling the belt section is registered in a server device, and the belt section is configured to be controlled based on this schedule, so that traffic restrictions or lifting restrictions can be efficiently implemented at multiple locations in a facility.

[0095] In the above-mentioned second embodiment, a schedule for controlling the belt unit is registered in the server device, and the belt unit is controlled based on this schedule. However, the present invention is not limited to this. The automatic opening / closing belt partition or the server device can be configured to detect when a predetermined time has passed or when a predetermined time has arrived, and to expand or contract the belt unit to a desired length.

[0096] [Embodiment 3] Incidentally, in the above-mentioned embodiment 1, a configuration in which the belt part of the automatic opening / closing belt partition is controlled by operating a remote control terminal carried by an operator has been described, but the present invention is not limited to this. If a user of the facility is present near the automatic opening / closing belt partition while the belt part is being unwound, if the unwounding of the belt part is continued, the belt part may come into contact with the user, causing injury to the user, or the belt part may buckle and no longer function as the blocking part of the present invention. Therefore, it is also possible to configure the belt part to stop unwounding if the presence of a person is detected while the belt part is being unwound, and to store the belt part once and unwound again if the buckling of the belt part is detected. In the present embodiment 3, an automatic opening / closing belt partition will be described in which the unwounding of the belt part is stopped if the presence of a person is detected while the belt part is being unwound, and to store the belt part once and unwound again if the buckling of the belt part is detected.

[0097] <Outline of the Automatic Opening and Closing Belt Partition 700> An overview of the automatic opening / closing belt partition 700 according to the third embodiment will be described below. Fig. 14 is an explanatory diagram of the overview of the automatic opening / closing belt partition 700 according to the third embodiment.

[0098] 14, when the belt reeling device 710 of the automatic opening / closing belt partition 700 receives a blocking portion extension command, it starts reeling out the belt portion 111 (S11). When the human presence sensor 717 detects a person, it stops reeling out the belt portion 111 (S12).

[0099] Furthermore, if the buckling sensor 718 (not shown) detects the buckling of the belt portion 111, the storage of the belt portion 111 is started (S13), and after storage, the payout is started again (S14). The buckling sensor 718 will be described in detail later.

[0100] In this way, in the automatic opening / closing belt partition 700 of this embodiment 3, if the presence of a person is detected while the belt portion 111 is being extended, the extension of the belt portion 111 is stopped, and if buckling of the belt portion 111 is detected, the belt portion is temporarily stored and extension is resumed again, so that passage restrictions or lifting restrictions can be efficiently and safely implemented at multiple locations in a facility.

[0101] <System configuration of automatic opening / closing belt partition system> Next, a description will be given of the system configuration of the automatic opening / closing belt partition system according to the embodiment 3. Fig. 15 is a diagram showing the system configuration of the automatic opening / closing belt partition system according to the embodiment 3.

[0102] In order to regulate the passage of users, a plurality of automatic opening / closing belt partitions 700 (for example, automatic opening / closing belt partitions 700a, 700b, etc.) are installed in the facility. The plurality of automatic opening / closing belt partitions 700 are capable of communicating with the transceiver 300 via wireless communication.

[0103] The server device 600 is communicatively connected to the automatic opening / closing belt partition 700 via the transceiver 300. The server device 600 transmits a blocking section extension instruction or a blocking section contraction instruction to the automatic opening / closing belt partition 700 based on a schedule stored in advance.

[0104] <Configuration of the automatic opening / closing belt partition 700> Next, the configuration of the automatic opening / closing belt partition 700 shown in Fig. 15 will be described. Fig. 16 is a functional block diagram showing the configuration of the automatic opening / closing belt partition 700 shown in Fig. 15. Note that the description of the functional parts similar to those of the automatic opening / closing belt partition 100 shown in Fig. 3 will be omitted.

[0105] As shown in FIG. 16, the automatic opening / closing belt partition 700 has a belt reeling device 710, a support 120, and a base 130.

[0106] The belt reeling device 710 is a device that controls the reeling of the belt portion 111, and has the belt portion 111, a storage section 112, a drive section 113, a communication section 114, a control section 715, a battery 116, a rotary encoder 117, a human sensor 717, and a buckling sensor 718.

[0107] The human sensor 717 is a sensor that detects the presence of a person within a predetermined distance. The buckling sensor 718 is a sensor that detects buckling of the aluminum tape of the belt part 111. For example, if an angular velocity sensor is installed at the tip of the aluminum tape and a current is passed through the aluminum tape, and the angular velocity sensor detects buckling, the angular velocity sensor can change the voltage of the current flowing through the aluminum tape, thereby detecting buckling of the aluminum tape as the buckling sensor 718. Note that the belt part 111 is wrapped in a cylindrical cloth or the like, so that the user will not receive an electric shock from the current flowing through the aluminum tape.

[0108] The control unit 715 is a control unit that performs overall control of the belt payout device 710, and has a belt portion payout control unit 715a and a belt portion storage control unit 715b. In practice, these programs are loaded into a CPU and executed, causing the belt portion payout control unit 715a and the belt portion storage control unit 715b to execute the processes corresponding thereto.

[0109] The belt portion payout control unit 715a is a processing unit that controls the payout of the belt portion 111. When the belt portion payout control unit 715a receives a blocking portion extension instruction, it transfers a payout instruction to the drive unit 113. When the human presence sensor 717 detects a person, the belt portion payout control unit 715a transfers a payout stop instruction to the drive unit 113.

[0110] The belt portion storage control unit 715b is a processing unit that controls storage of the belt portion 111. Upon receiving the blocking portion contraction instruction, the belt portion storage control unit 715b transfers the storage instruction to the drive unit 113.

[0111] Furthermore, if the buckling sensor 718 detects buckling of the aluminum tape of the belt portion 111 while the belt portion 111 is being paid out by the drive portion 113, the belt portion storage control portion 715b passes a storage instruction to the drive portion 113. Then, if the belt portion storage control portion 715b detects completion of storage of the belt portion 111 based on the amount of rotation received from the rotary encoder 117, it passes a blocking portion extension instruction to the belt portion payout control portion 715a.

[0112] <Control procedure of the belt part of the automatic opening / closing belt partition 700> Next, a description will be given of a control procedure for the belt portion of the automatic opening / closing belt partition 700 according to the third embodiment. Fig. 17 is a flowchart showing a control procedure for the belt portion of the automatic opening / closing belt partition 700 according to the third embodiment.

[0113] As shown in FIG. 17, the belt unwinding device 710 of the automatic opening / closing belt partition 700 waits to receive an instruction to extend the blocking section (step S201; No), and after receiving the instruction to extend the blocking section (step S201; Yes), if the human presence sensor 717 detects a person (step S202; Yes), it stops unwinding the belt section 111 (step S203) and proceeds to step S202.

[0114] If the human presence sensor 717 does not detect a person (step S202; No) and the buckling sensor 718 detects buckling of the aluminum tape of the belt portion 111 (step S204; Yes), the belt portion 111 is stored (step S205) and waits until it detects that the belt portion 111 has been stored completely based on the amount of rotation received from the rotary encoder 117 (step S206; No). If it detects that the belt portion 111 has been stored completely (step S206; Yes), the process proceeds to step S202.

[0115] If the human sensor 717 does not detect a human (step S202; No) and the buckling sensor 718 does not detect buckling of the aluminum tape of the belt portion 111 (step S204; No), the belt portion 111 is unwound (step S207).

[0116] If the rotary encoder 117 does not detect the completion of payout of the belt portion 111 (step S208; No), the process proceeds to step S202. If the rotary encoder 117 detects the completion of payout of the belt portion 111 (step S208; Yes), the process ends.

[0117] As described above, in the automatic opening / closing belt partition of this embodiment 3, if the presence of a person is detected while the belt portion is being extended, the extension of the belt portion is stopped, and if buckling of the belt portion is detected, the belt portion is temporarily stored and then extended again, thereby making it possible to efficiently and safely restrict or lift restrictions on passage at multiple locations in a facility.

[0118] In the above-mentioned third embodiment, the belt unwinding device stops unwinding the belt when the presence of a person is detected while the belt is being unwound, and stores the belt when buckling of the belt is detected, and then unwinds the belt again. However, the present invention is not limited to this. The belt unwinding device can be configured to communicate with a Wi-Fi router connected to the Internet using Wi-Fi (registered trademark), so that the belt unwinding device can notify a predetermined terminal connected to the Internet at a remote location of the unwinding status and buckling status of the belt.

[0119] [Embodiment 4] Incidentally, in the above-mentioned embodiment 3, a configuration has been described in which, if the presence of a person is detected while the belt portion 111 is being unwound, the unwounding of the belt portion 111 is stopped, and, if buckling of the belt portion 111 is detected, the belt portion is temporarily stored and unwound again, but the present invention is not limited to this. It may also be configured to notify the occurrence of an abnormality when the number of consecutive detections of the presence of a person and buckling while the belt portion 111 is being unwound reaches a predetermined number, or when the user falls over. In the present embodiment 4, an automatic opening / closing belt partition will be described, which stops the unwounding of the belt portion 111 when the presence of a person is detected while the belt portion 111 is being unwound, temporarily stores the belt portion and then unwound again when buckling is detected, and notifies the occurrence of an abnormality when the number of consecutive detections of the presence of a person and buckling reaches a predetermined number, or when the user falls over.

[0120] <Outline of the Automatic Opening and Closing Belt Partition 800> An overview of the automatic opening / closing belt partition 800 according to the fourth embodiment will be described below. Fig. 18 is an explanatory diagram of the overview of the automatic opening / closing belt partition 800 according to the fourth embodiment.

[0121] As shown in FIG. 18, when the belt unwinding device 810 of the automatic opening / closing belt partition 800 receives a blocking section extension command, it starts unwinding the belt portion 111 (S21). When the human presence sensor 717 detects a person, it stops unwinding the belt portion 111 (S22). When the buckling sensor 718 detects buckling, it stores the belt portion once and then starts unwinding again (S23). When the tipping sensor detects the tipping of the automatic opening / closing belt partition 800 (S24), or when the number of times that people are detected and the number of times that buckling is detected exceed a predetermined number before the unwinding of the belt portion 111 is completed, it issues an alarm from the alarm device 850 (S25). For example, it issues a voice message saying "An abnormality has occurred in the belt partition."

[0122] In this way, the automatic opening / closing belt partition 800 of this embodiment 4 is configured to notify of the occurrence of an abnormality when the number of times the presence of a person is detected while the belt portion 111 is being extended and the extension of the belt portion 111 is stopped, when the number of times buckling of the belt portion is detected and the belt portion is once stored and then extended again exceeds a predetermined number, and when a tip-over of the automatic opening / closing belt partition is detected, so that traffic restrictions or lifting restrictions can be efficiently and safely implemented at multiple locations in a facility.

[0123] <System configuration of automatic opening / closing belt partition system> Next, a description will be given of the system configuration of the automatic opening / closing belt partition system according to the embodiment 4. Fig. 19 is a diagram showing the system configuration of the automatic opening / closing belt partition system according to the embodiment 4.

[0124] In order to regulate the passage of users, a plurality of automatic opening / closing belt partitions 800 (for example, automatic opening / closing belt partitions 800a, 800b, etc.) are installed in the facility. The plurality of automatic opening / closing belt partitions 800 can communicate with the transceiver 300 via wireless communication.

[0125] The server device 600 and the alarm device 850 are communicatively connected to the automatic opening / closing belt partition 800 via the transceiver 300. The server device 600 transmits a blocking section extension command or a blocking section contraction command to the automatic opening / closing belt partition 800 based on a schedule stored in advance.

[0126] When the alarm device 850 receives an alarm instruction from the automatic opening / closing belt partition 800, it issues an alarm by voice.

[0127] <Configuration of the Automatic Opening and Closing Belt Partition 800> Next, the configuration of the automatic opening / closing belt partition 800 shown in Fig. 19 will be described. Fig. 20 is a functional block diagram showing the configuration of the automatic opening / closing belt partition 800 shown in Fig. 19. Note that the description of the functional parts similar to those of the automatic opening / closing belt partition 700 shown in Fig. 16 will be omitted.

[0128] As shown in FIG. 20, the automatic opening / closing belt partition 800 has a belt reeling device 810, a support 120, and a base 130.

[0129] The belt unwinding device 810 is a device that controls the unwinding of the belt portion 111, and has the belt portion 111, a storage section 112, a drive section 113, a communication section 114, a control section 815, a battery 116, a human sensor 717, a buckling sensor 718, and a fall sensor 819.

[0130] The falling sensor 819 is a sensor that detects that the automatic opening / closing belt partition 800 has fallen over.

[0131] The control unit 815 is a control unit that performs overall control of the belt payout device 810, and has a belt portion payout control unit 715a, a belt portion storage control unit 715b, and an alarm control unit 815c. In practice, these programs are loaded into a CPU and executed, causing the belt portion payout control unit 715a, the belt portion storage control unit 715b, and the alarm control unit 815c to execute processes corresponding thereto.

[0132] The alarm control unit 815c is a processing unit that transmits an alarm instruction to the alarm device 850. The alarm control unit 815c transmits an alarm instruction to the alarm device 850 when the number of consecutive detections of a person by the human presence sensor 717 and buckling by the buckling sensor 718 reaches a predetermined number, or when the tipping sensor 819 detects the tipping of the automatic opening / closing belt partition 800.

[0133] <Control procedure for the belt part of the automatic opening / closing belt partition 800> Next, a description will be given of a control procedure for the belt portion of the automatic opening / closing belt partition 800 according to the embodiment 4. Fig. 21 is a flowchart showing a control procedure for the belt portion of the automatic opening / closing belt partition 800 according to the embodiment 4.

[0134] As shown in FIG. 21, the belt unwinding device 810 of the automatic opening / closing belt partition 800 waits to receive an instruction to extend the blocking section (step S301; No), and after receiving the instruction to extend the blocking section (step S301; Yes), if the human presence sensor 717 detects a person (step S302; Yes), it stops unwinding the belt section 111 (step S303).

[0135] The counter is incremented (step S311), and if the counter is equal to or less than a predetermined threshold (step S312; No), the process proceeds to step S302. If the counter exceeds a predetermined threshold (step S312; Yes), a warning instruction is sent to the warning device 850 (step S313), and the process ends.

[0136] In step S302, if the human presence sensor 717 does not detect a person (step S302; No) and the buckling sensor 718 detects buckling of the aluminum tape of the belt portion 111 (step S304; Yes), the belt portion 111 is stored (step S305) and detection of completion of storage of the belt portion 111 based on the amount of rotation received from the rotary encoder 117 is awaited (step S306; No). If completion of storage of the belt portion 111 is detected (step S306; Yes), the process proceeds to step S311.

[0137] In step S304, if the buckling sensor 718 does not detect buckling of the aluminum tape of the belt portion 111 (step S304; No) and the tipping sensor 819 detects the tipping of the automatic opening / closing belt partition 800 (step S307; Yes), an alarm instruction is sent to the alarm device 850 (step S313), and the processing ends.

[0138] In step S307, if the fall sensor 819 does not detect the fall of the automatic opening / closing belt partition 800 (step S307; No), the counter is reset to zero (step S308), and the belt portion 111 is unwound (step S309).

[0139] If the rotary encoder 117 does not detect the completion of payout of the belt portion 111 (step S310; No), the process proceeds to step S302. If the rotary encoder 117 detects the completion of payout of the belt portion 111 (step S310; Yes), the process ends.

[0140] As described above, in the automatic opening / closing belt partition of this embodiment 4, if the presence of a person is detected while the belt is being extended, the extension of the belt is stopped, and if buckling is detected, the belt is temporarily stored and then extended again. In addition, if the number of consecutive detections of the presence of a person and buckling reaches a predetermined number or if a fall occurs, an alert is issued to notify the user that an abnormality has occurred, so that restrictions on passage or lifting restrictions can be efficiently and safely implemented at multiple locations in a facility.

[0141] [Embodiment 5] In the above embodiment 1, the belt unwinding device is attached to the top of the support pole, but the present invention is not limited to this. The belt unwinding device can also be attached to the top of a triangular cone. In the present embodiment 5, an automatic opening and closing belt partition in which the belt unwinding device is attached to the top of a triangular cone is described.

[0142] <Outline of the Automatic Opening and Closing Belt Partition 900> An overview of the automatic opening / closing belt partition 900 according to the fifth embodiment will be described below. Fig. 22 is an explanatory diagram of the overview of the automatic opening / closing belt partition 900 according to the fifth embodiment.

[0143] 22, the automatic opening / closing belt partition 900 has an appearance in which the belt reeling device 110 is attached to the top of a triangular cone 920. When an operator operates the remote control terminal 200, the remote control terminal 200 transmits a blocking section extension command to the belt reeling device 110 (S31).

[0144] When the belt reeling device 110 receives the blocking portion extension instruction, it reels out the belt portion 111 (S32). This makes it possible to efficiently restrict or lift the restriction on pedestrians and the like at the entrance and exit of construction vehicles at the construction site.

[0145] In the above-mentioned embodiment 5, the belt payout device is attached to the top of the triangular cone, but the present invention is not limited to this. It is also possible to configure the belt payout device to be attached to the top of an existing belt partition that is operated manually. Also, it is also possible to configure the belt payout device to be attached to a robot that patrols security inside the facility.

[0146] In addition, in each of the above embodiments, a configuration in which one belt payout device is attached to the top of the belt partition or the triangular cone has been described, but the present invention is not limited to this.
