Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when trying to install the above-described operation buttons in an elevator in a building with a large number of floors, since the number of destination floor registration buttons increases, there is a problem that it takes time for visually impaired persons to find the desired destination floor button, making the car call registration operation difficult.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide an elevator system, a car call registration device, and a car call registration method that enable visually impaired persons to perform car call registration operations with simple operations.

Means for Solving the Problems

[0006] According to an embodiment for achieving the above object, a car call registration device is communicably connected to an operation unit installed in an elevator car and rotatable in a predetermined direction by a user's operation, and a speaker device installed in the car, and includes a rotation detection unit, an output control unit, and a registration processing unit. The rotation detection unit detects the amount of rotation of the operation unit during the rotation operation of the operation unit by the user, and identifies the floor corresponding to the detected amount of rotation. The output control unit causes the speaker device to output the floor information identified by the rotation detection unit. When the registration processing unit detects that the rotation operation by the user has been completed in a state where the operation unit has rotated by a predetermined amount, the registration processing unit registers a car call with the floor identified by the rotation detection unit corresponding to the amount of rotation of the operation unit when the completion of the rotation operation is detected as the destination floor.

Modes for Carrying Out the Invention

[0008] 《First Embodiment》 〈Configuration of an Elevator System Using a Car Call Registration Device According to the First Embodiment〉 FIG. 1 is an overall view showing the configuration of an elevator system 1A using a car call registration device according to the present embodiment. The elevator system 1A includes a hoisting machine 3 installed above a hoistway 2 in a building, a rope 4 spanned over the hoisting machine 3, a car 5A suspended from one end of the rope 4, and an elevator control device 10A installed above the hoistway 2 and connected to the car 5A via a tail cord 6. Inside the car 5A, an in-car operation panel 51-1 is installed.

[0009] FIG. 2 is a front view of the in-car operation panel 51-1. The in-car operation panel 51-1 has a destination floor button group 511, a door close button 512, a door open button 513, a dial-type first operation unit 514, a speaker device 515, and a display device 516. As shown in FIG. 2, by installing the first operation unit 514 below the in-car operation panel 51-1, even a child can easily operate it.

[0010] The destination floor button group 511 has a plurality of destination floor designation buttons installed for each floor so that a general user can specify a destination floor and perform a car call operation.

[0011] The first operation unit 514 is an operation unit used by a visually impaired person to specify a destination floor and perform a car call operation, and is composed of members capable of rotation operation and pressing operation. Specifically, the first operation unit 514 has a cylindrical shape, one bottom surface is installed on the front surface of the in-car operation panel 51-1, can rotate clockwise and counterclockwise around the central axis of the cylinder as the rotation axis, and is configured to be pushable in the direction from the front surface side to the back surface side of the in-car operation panel 51-1, that is, from the front side of the user to the back side, which is the central axis direction of the cylinder.

[0012] The elevator control device 10A is communicably connected to the car 5A and has a call registration unit 11 and a CPU 12A. The call registration unit 11 registers a car call and a landing call based on the operation of the user.

[0013] The CPU 12A is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and constitutes one or more of the following information processing units by installing and executing a predetermined elevator control program. The CPU 12A includes an operation control unit 121, an in-car information processing unit 122, a rotation detection unit 123, an output control unit 124A, and a registration processing unit 125A. The rotation detection unit 123, the output control unit 124A, and the registration processing unit 125A constitute the car call registration device 20A.

[0014] The operation control unit 121 controls the operation of devices including the hoist 3 so as to respond to calls registered in the call registration unit 11. The in-car information processing unit 122 acquires information from devices in the car 5A via the tail cord 6 and transmits information to devices in the car 5A.

[0015] Based on the information acquired by the in-car information processing unit 122, the rotation detection unit 123 detects the rotation direction and rotation amount of the first operation unit 514 during the rotation operation of the first operation unit 514 by the user, and identifies the floor corresponding to the detected rotation direction and rotation amount. Each time the floor identified by the rotation detection unit 123 changes, the output control unit 124A causes the information of the identified floor to be output from the speaker device 515.

[0016] When the registration processing unit 125A detects that the rotation operation by the user has been completed with the first operation unit 514 rotated by a predetermined amount, the registration processing unit 125A registers a car call in the call registration unit 11 with the floor identified by the rotation detection unit 123 corresponding to the rotation state of the first operation unit 514 when the rotation operation is completed as the destination floor. Further, when the registration processing unit 125A detects that any one of the destination floor button groups 511 has been operated, the registration processing unit 125A registers a car call in the call registration unit 11 with the floor corresponding to the operated button as the destination floor.

[0017] <Operation of the Elevator System According to the First Embodiment> The operation of the elevator system 1A will be described. When the car 5A lands at the landing and the door opens during the operation of the elevator system 1A, the in-car information processing unit 122 acquires the landing floor information and door opening information of the car 5A. When the output control unit 124A detects that the car 5A has opened the door at a predetermined floor based on the information acquired by the in-car information processing unit 122, based on this, announcement information for notifying that the dial-type first operation unit 514, which is an operation unit for registering a car call for visually impaired persons, is installed in the car 5A is output from the speaker device 515.

[0018] Here, the process when the visually impaired person X1 gets into the car 5A and registers a car call using the first operation unit 514 will be described.

[0019] FIG. 3 is a flowchart showing the process executed by the elevator control device 10A when a car call is registered in the elevator system 1A.

[0020] When the visually impaired person X1 rotates the first operation unit 514, the information on the rotation direction and rotation amount of the first operation unit 514 is transmitted from the in-car operation panel 51-1 to the elevator control device 10A and acquired by the rotation detection unit 123 via the in-car information processing unit 122.

[0021] The rotation detection unit 123 recognizes that the first operation unit 514 has been rotated based on the acquired information (``YES'' in S1), and detects the rotation direction and rotation amount of the first operation unit 514.

[0022] The rotation detection unit 123 acquires the current position information of the car 5A from the operation control unit 121, and specifies the floor having the direction and distance from the current position of the car 5A corresponding to the detected rotation direction or rotation amount of the first operation unit 514 (S2).

[0023] For example, when the rotation detection unit 123 detects that the first operation unit 514 has rotated 60° in the clockwise direction while the car 5A is landing on the 8th floor, it identifies the 9th floor, which is one floor above the current position of the car 5A, as the floor corresponding to the detected rotation situation. Also, when the rotation detection unit 123 detects that the first operation unit 514 has rotated 120° in the clockwise direction while the car 5A is landing on the 8th floor, it identifies the 10th floor, which is two floors above the current position of the car 5A, as the floor corresponding to the detected rotation situation. Further, when the rotation detection unit 123 detects that the first operation unit 514 has rotated 60° in the counterclockwise direction while the car 5A is landing on the 8th floor, it identifies the 7th floor, which is one floor below the current position of the car 5A, as the floor corresponding to the detected rotation situation. Note that when identifying the floor corresponding to the rotation situation, the rotation direction and the rotation amount are not limited to those described above and may be arbitrarily set.

[0024] The output control unit 124A causes the speaker device 515 to output announcement information for notifying the floor specified by the rotation detection unit 123 (S3). While the visually impaired person X1 continues the rotation operation of the first operation unit 514 (''NO'' in S4), the output control unit 124A causes the speaker device 515 to output announcement information for notifying the floor after the change each time the floor specified by the rotation detection unit 123 changes. For example, when the visually impaired person X1 continuously rotates the first operation unit 514 in the clockwise direction and the first operation unit 514 rotates as 60° → 120° → 180° ···, the output control unit 124A sequentially outputs announcement information such as ''9th floor'', ''10th floor'', ''11th floor'' ··· from the speaker device 515 accordingly.

[0025] The visually impaired person X1 listens to the announcement information output from the speaker device 515 while rotating the first operation unit 514, and when announcement information corresponding to the desired destination floor, for example, ''11th floor'', is output, stops the rotation operation. Then, in order to notify the completion of the rotation operation, the visually impaired person X1 presses the first operation unit 514 from the front side toward the back side, that is, from the front surface side of the in-car operation panel 51-1 toward the back surface side.

[0026] When visually impaired person X1 presses the first operation unit 514, information on this pressing operation is transmitted to the elevator control device 10A and acquired by the registration processing unit 125A via the car interior information processing unit 122.

[0027] Based on the acquired information, the registration processing unit 125A detects that the first operation unit 514 has been pressed by the user in a state where the first operation unit 514 has rotated by a predetermined amount. Based on the detected information, the registration processing unit 125A recognizes that the rotation operation of the first operation unit 514 by the user has been completed ("YES" in S4).

[0028] When the registration processing unit 125A recognizes that the rotation operation of the first operation unit 514 by the user has been completed, it registers a car call in the call registration unit 11 with the floor "11th floor" specified by the rotation detection unit 123 corresponding to the rotation direction and rotation amount of the first operation unit 514 when the rotation operation was completed as the destination floor (S5). When the car call is registered, the output control unit 124A causes the speaker device 515 to output announcement information notifying that the car call has been registered with the "11th floor" as the destination floor.

[0029] In step S1, when the first operation unit 514 is not rotated ("NO" in S1) and any one of the destination floor buttons in the destination floor button group 511 is operated ("YES" in S6), the registration processing unit 125A registers a car call in the call registration unit 11 with the floor corresponding to the operated button as the destination floor (S7).

[0030] According to the above first embodiment, even when there are many service floors in the elevator, a visually impaired person can easily specify the destination floor and perform a car call registration operation using one operation unit inside the car. In addition, the first operation unit installed for a visually impaired person to perform a car call registration operation can perform both an operation of rotating to output information on candidates for the destination floor and an operation of pressing to select the destination floor from the candidates. Therefore, it can be installed even when the space inside the car operation panel is small.

[0031] In the above-described first embodiment, the case where the registration processing unit 125A recognizes that the rotation operation is completed when detecting that the first operation unit 514 is pressed from the front side toward the back side has been described. However, the present invention is not limited to this, and when a force is applied to the first operation unit 514 by the user in the upward, downward, or lateral direction, it may be recognized that the rotation operation is completed. Alternatively, the registration processing unit 125A may recognize that the rotation operation is completed when the first operation unit 514 is stopped after rotating by a predetermined amount and a predetermined time has elapsed without any operation being performed thereafter.

[0032] Further, in the above-described first embodiment, the case where one in-car operation panel 51-1 is installed in the car 5A has been described. However, the present invention is not limited to this, and two or more in-car operation panels 51-1 may be installed. For example, the in-car operation panel 51-1 may be installed near the car door (not shown) in the car 5A and on the side plate facing the car door. By installing a plurality of in-car operation panels 51-1 in the car 5A in this way, even when a plurality of visually impaired persons board the car 5A at different positions, it becomes easier for each of them to perform the car call registration operation.

[0033] When a plurality of in-car operation panels 51-1 are installed in the car 5A in this way, when a rotation operation is performed on one first operation unit 514 among these plurality of in-car operation panels 51-1, the other first operation units 514 may also rotate in conjunction with this. In this case, the plurality of in-car operation panels 51-1 may be physically connected to each other by a belt or the like, or may be electrically connected by wireless communication.

[0034] By configuring in this way, for example, when a visually impaired person X1 attempts to execute a car call registration operation using the first operation unit 514 located nearby within the car 5A, if this first operation unit 514 is rotating automatically, it is possible to recognize that another visually impaired person is in the middle of a car call registration operation using another in-car operation panel 51-1 within the car 5A. At this time, the visually impaired person X1 interrupts the car call registration operation and waits until the car call registration by another visually impaired person is completed and announcement information indicating the destination floor due to this car call registration is output from the output control unit 124A. The visually impaired person X1 listens to the output announcement information and can recognize that there is no need to perform a car call registration operation if the destination floor indicated by this announcement information is the same as the destination floor of the visually impaired person X1, thus saving the trouble of the operation.

[0035] 《Second Embodiment》 〈Configuration of Elevator System Using Car Call Registration Device According to Second Embodiment〉 FIG. 4 is an overall view showing the configuration of an elevator system 1B using the car call registration device according to this embodiment. The elevator system 1B has a camera device 52 installed within the car 5B and has a determination unit 126 within the CPU 12B in the elevator control device 10B. Otherwise, it has the same configuration as the elevator system 1A described in the first embodiment, so detailed descriptions of parts with the same functions are omitted.

[0036] The camera device 52 photographs the inside of the car 5B and transmits the imaging information to the elevator control device 10B.

[0037] The determination unit 126 acquires and analyzes the imaging information photographed by the camera device 52 to determine whether there is a visually impaired person within the car 5B. Further, when the determination unit 126 determines that there is a visually impaired person within the car 5B, it further determines whether there is a user other than this visually impaired person within the car 5B.

[0038] When the determination unit 126 determines that there is a visually impaired person in the car 5B and the registration processing unit 125B detects that the rotation operation by the user has been completed with the first operation unit 514 rotated by a predetermined amount, it registers a car call.

[0039] When the determination unit 126 determines that there are a plurality of users including a visually impaired person in the car 5B, the output control unit 124B causes the speaker device 515 to output announcement information indicating the floor corresponding to the currently registered call to the call registration unit 11 as the floor information of the registered call.

[0040] <Operation of Elevator System According to Second Embodiment> The operation when a car call is registered in the elevator system 1B will be described. FIG. 5 is a flowchart showing the processing executed by the elevator control device 10B when a car call is registered in the elevator system 1B.

[0041] In the present embodiment, during the operation of the elevator system 1B, the camera device 52 captures the inside of the car 5B and sequentially transmits the imaging information to the elevator control device 10B. In the elevator control device 10B, the determination unit 126 acquires the imaging information transmitted from the camera device 52, performs analysis processing at a predetermined time interval, and determines whether or not there is a visually impaired person X2 in the car 5B (''YES'' in S11).

[0042] For example, when the determination unit 126 detects a person carrying a white cane or a person performing a predetermined operation by analyzing the imaging information, it determines that there is a visually impaired person X2 in the car 5B. In order to execute such determination processing, the camera device 52 may be configured as an AI (Artificial Intelligence) camera to improve the accuracy of analysis.

[0043] When the determination unit 126 determines that there is a visually impaired person X2 in the car 5B, the output control unit 124B may cause the speaker device 515 to output announcement information notifying that the dial-type first operation unit 514, which is an operation unit for registering a car call for the visually impaired, is installed in the car 5B.

[0044] When the determination unit 126 determines that there is a visually impaired person X2 in the car 5B, it further analyzes the imaging information to determine whether there is a user other than the visually impaired person X2 in the car 5B (S12).

[0045] When the determination unit 126 determines that there is a user other than the visually impaired person X2 in the car 5B (``YES'' in S12), that is, when it determines that there are a plurality of users including the visually impaired person in the car 5B, the output control unit 124B causes the speaker device 515 to output the floor information corresponding to the call currently registered in the call registration unit 11 as the floor information of the registered call (S13). Thereby, the visually impaired person X2 in the car 5A can determine whether it is necessary to perform a car call operation by designating the destination floor.

[0046] Thereafter, the processes executed in steps S14 to S20 are the same as the processes of S1 to S7 described in the first embodiment, so detailed description is omitted. However, in step S18, the registration processing unit 125B registers a car call when the determination unit 126 determines that there is a visually impaired person in the car 5B and detects that the rotation operation by the user has been completed in a state where the first operation unit 514 has rotated by a predetermined amount. By performing the process in this way, it is possible to prevent a car call from being registered due to a prank or an erroneous operation in the first operation unit 514.

[0047] Also in the second embodiment described above, similar to the case described in the first embodiment, a plurality of in-car operation panels 51-1 may be installed in the car 5B. Further, these plurality of in-car operation panels 51-1 may be physically or electrically connected to each other so that their operations are interlocked.

[0048] In the above-described first and second embodiments, the case where the operation unit for visually impaired persons to specify the destination floor and perform the car call operation within the car operation panel 51-1 is configured by the dial-type first operation unit 514 has been described. However, the present invention is not limited to this. As shown in the car operation panel 51-2 in FIG. 6, the operation unit for visually impaired persons to perform the car call operation may be configured by a second operation unit 517 that can rotate when a force is applied in the vertical direction. This second operation unit 517 is configured by exposing a part of a member that rotates about an axis parallel to the width direction of the car operation panel 51-2 on the surface of the car operation panel 51-2.

[0049] When the car operation panel 51-2 is configured using the second operation unit 517 in this way, for example, when the rotation detection unit 123 detects that the second operation unit 517 has rotated 60° due to an upward force being applied when the car 5A or 5B has landed on the 8th floor, it identifies the 9th floor, which is one floor above the current position of the car 5A or 5B, as the floor corresponding to the detected rotation situation. Also, when the rotation detection unit 123 detects that the second operation unit 517 has rotated 120° due to an upward force being applied when the car 5A or 5B has landed on the 8th floor, it identifies the 10th floor, which is two floors above the current position of the car 5A or 5B, as the floor corresponding to the detected rotation situation. Further, when the rotation detection unit 123 detects that the second operation unit 517 has rotated 60° due to a downward force being applied when the car 5A or 5B has landed on the 8th floor, it identifies the 7th floor, which is one floor below the current position of the car 5A or 5B, as the floor corresponding to the detected rotation situation.

[0050] Also in this case, the output control unit 124A or 124B causes the speaker device 515 to output announcement information for notifying the floor identified by the rotation detection unit 123. A visually impaired person listens to the announcement information output from the speaker device 515 while rotating the second operation unit 517, and stops the rotation operation when the announcement information corresponding to the desired destination floor is output. When the second operation unit 517 is stopped in a state where it has rotated a predetermined amount and a predetermined time has elapsed without any operation being performed thereafter, the registration processing unit 125A or 125B recognizes that the rotation operation has been completed. The registration processing unit 125A or 125B registers a car call in the call registration unit 11 with the floor identified by the rotation detection unit 123 corresponding to the rotation direction and rotation amount of the second operation unit 517 at this time as the destination floor.

[0051] By configuring the in-car operation panel 51-2 using the second operation unit 517 in this way, a visually impaired person can easily specify the destination floor and perform a car call registration operation.

[0052] Further, the first operation unit 514 or the second operation unit 517 may have a concave portion or a convex portion at a predetermined position on the outer peripheral surface corresponding to the rotation amount for each floor. For example, concave portions or convex portions are provided at predetermined intervals in the rotation direction on the outer peripheral surface of the first operation unit 514 or the second operation unit 517 having a cylindrical shape. By configuring in this way, when a visually impaired person operates the first operation unit 514 or the second operation unit 517, it is possible to grasp how much rotation is required to raise or lower the designated target floor by one floor.

[0053] Further, by using the concave portion or the convex portion provided in this way, the first operation unit 514 or the second operation unit 517 may be configured as a latch-type operation unit that allows a visually impaired person to recognize the floor corresponding to the rotation amount one floor at a time by touch when rotating. By configuring the first operation unit 514 or the second operation unit 517 in this way, a visually impaired person can more easily specify the destination floor and perform a car call registration operation.

[0054] Although some embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalent scope thereof.
