Elevator system, call control method, hall control device, and call program

Abstract

If a user who has registered a call by operating the platform button later chooses the stairs and leaves the platform, the elevator car will arrive and open its doors even though other people at the platform have no intention of using the elevator, resulting in a decrease in operational efficiency. [Solution] The elevator comprises a hall monitoring unit with a specific detection range at the hall, an operation unit that accepts call registrations by users at the hall, an elevator control unit that controls the operation of the car based on the call registrations, an alarm unit that notifies of calls registered by the operation unit, and a call control unit that, when a person enters the detection range while a call has been registered, determines whether the person is a user based on the person's actions and registers the user, and when a user who has registered a call at the operation unit leaves the detection range, the call control unit maintains the call registration if another user corresponding to the call registration of the user who left is registered, or cancels the call registration if the user is not registered.

Description

[Technical Field]

[0001] The present disclosure relates to an elevator system, a call control method, a hall control device, and a call program. [Background technology]

[0002] After pressing the elevator button at an elevator hall to register a call, passengers may stop using the elevator and use the stairs or escalator instead. In such cases, if the call remains registered, the car will arrive at the hall and open the doors. This reduces the elevator's operational efficiency and causes discomfort to passengers.

[0003] Therefore, in Patent Document 1, after a user operates the platform button to register a call, if the detection unit detects that there is no one at the platform before the car arrives, the call registration is canceled. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-113179 Summary of the Invention [Problem to be solved by the invention]

[0005] In the elevator described in Patent Document 1, even if a user who pressed the hall button later chooses the stairs and leaves the hall, the call registration is maintained if there is another person at the hall. However, there are cases where the person at the hall simply passed by the hall, or is on the phone at the hall and has no intention of boarding. If the car arrives and the door opens despite this, operation efficiency will decrease.

[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an elevator control system that can infer the intention of people at a landing after a person who has registered a call using a landing button leaves the landing, and appropriately maintain or cancel the call registration. [Means for solving the problem]

[0007] The elevator system of the present disclosure includes a hall monitoring unit having a specific detection range at the hall, an operation unit that accepts call registrations by users at the hall, an elevator control unit that controls the operation of the car based on the call registrations, an alarm unit that notifies of calls registered by the operation unit, and a call control unit that, when a person enters the detection range while a call has been registered, determines whether the person is a user based on the person's actions and registers the user, and when a user who has registered a call at the operation unit leaves the detection range, the call control unit maintains the call registration if another user corresponding to the call registration of the exiting user is registered, and cancels the call registration if the user is not registered. [Effects of the Invention]

[0008] According to the present disclosure, after a person who has registered a call using the platform button leaves the platform, the call registration can be appropriately maintained or canceled, thereby improving operation efficiency. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure will be described with reference to the accompanying drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and redundant explanations will be appropriately simplified or omitted.

[0011] Embodiment 1 Figure 1 is a diagram showing the structure of an elevator. Elevator car 1 is installed in a hoistway 2 provided in a building. Car 1 moves within hoistway 2 between multiple floors, in this case, from the lowest floor, floor 1, to the top floor.

[0012] A machine room 3 is provided directly above the elevator shaft 2. In the machine room 3, a hoisting machine 4, a hoisting machine control panel 5, a deflection sheave 6, and an elevator control device 20 are provided.

[0013] The car 1 and the counterweight 7 are connected to both ends of a rope 8. The rope 8 is hung between the hoisting machine 4 and the deflector pulley 6, and the car 1 and the counterweight 7 are suspended from the rope 8.

[0014] In this elevator, a traction machine control panel 5 controls the rotation and stopping of a traction machine 4, thereby causing a car 1 installed in a hoistway 2 to travel upward or downward.

[0015] At each floor, a landing 11 is provided in front of a landing door 10 for boarding the car 1. When the car 1 arrives at a floor, the driving motor opens the car door 9, and the landing door 10 also opens in conjunction with this, allowing passengers at the landing 11 to board the car 1.

[0016] A hall controller 30 is installed at each hall 11. This hall controller 30 is connected to the elevator controller 20 via a communication line 12, and is capable of transmitting and receiving information to and from the elevator controller 20.

[0017] 2 and 3 are diagrams showing an outline of the hall control device 30, with FIG. 2 being a configuration diagram and FIG. 3 being a layout diagram at the hall.

[0018] The hall control device 30 has an operation unit 31, a notification unit 32, a hall monitoring unit 33, and a call control unit 34. The call control unit 34 has an entry / exit detection unit 341, a determination unit 342, a memory unit 343, a call cancellation unit 344, and an operation response unit 345.

[0019] The operation unit 31 is provided with a landing button 311 that is located near the landing door 10 and is installed on the wall of the landing 11. The landing button 311 includes an up button 311a that is pressed when the user wants to go up, and a down button 311b that is pressed when the user wants to go down. When a user presses these buttons, a call is registered. That is, for example, when the up button 311a is pressed, a call request is sent to the elevator control device 20 to have the car 1 come to the landing in the up direction. The elevator control device 20 accepts the request, and the hoist control panel 5 controls the drive of the hoist 4, causing the car 1 to arrive at the landing 11. Furthermore, the up button 311a and the down button 311b each have a light-emitting element inside, and when a user presses one of them, the light remains lit until the car 1 in that direction arrives at the landing 11.

[0020] The notification unit 32 is composed of an up / down lamp 32a that indicates the direction of the car 1 and a display panel 32b that indicates the current position of the car 1. The up / down lamp 32a indicates whether the car 1 approaching the hall 11 is going up or down. For example, when the elevator control device 20 receives an up call request from the operation unit 31, the part of the up / down lamp 32a that indicates the up direction lights up.

[0021] The landing monitoring unit 33 includes a camera 33a that is installed on the wall surface of the landing 11 above the landing door 10 and has the landing 11 as its imaging (detection) range.

[0022] The entry / exit detection unit 341 identifies a person from the image captured by the camera 33a and analyzes the movement of that person, thereby detecting whether a new person has entered the capture range of the hall 11 or whether a person has exited the capture range.

[0023] The storage unit 343 has a user table 3431 shown in FIG. The user table 3431 is divided into an upbound user table and a downbound user table. Each table has columns for direction, user identifier, and reason for determination. The user identifier is an identifier that is arbitrarily and sequentially assigned to a person who will become a user. Note that the entry / exit detection unit 341 deletes the registration when a user registered in the user table 3431 exits the imaging range of the hall 11.

[0024] When the entry / exit detection unit 341 detects a person who has entered the photographing range of the hall 11, the determination unit 342 determines whether to register the person in the user table 3431. That is, the determination unit 342 infers from the behavior of the person who has newly entered the photographing range whether or not the person intends to use the elevator, and if it can be determined that the person intends to use the elevator, the determination unit 342 registers the person in the user table 3431.

[0025] Usually, when a person wants to use an elevator, they come to the hall 11 and check whether their call has been registered, that is, whether someone has already pressed the hall button 311 for the direction they want to go. If not, they press the hall button 311 themselves to register their call.

[0026] This confirmation is performed by visually checking the up / down lamp 32a or the up button 311a and down button 311b. If the up button 311a or down button 311b has already been pressed, these buttons will light up, and if the call has been registered, the up / down lamp 32a will light up.

[0027] Therefore, here, whether or not the person who entered has made an action to check is inferred from the person's line of sight and the direction of the body. Specifically, first, the image is analyzed to identify the direction in which the person's body is facing, and the positions of both eyes are identified. Then, the person's body is turned toward the wall where the landing door 10 is located. Furthermore, the up / down lamp 32a, or the up button 311a and the down button 311b are located on a vertical line extending perpendicular to the center of the line connecting the two eyes. If this state continues for two seconds, it can be inferred that the person intends to use the elevator, and this is registered in the user table 3431.

[0028] The call cancellation unit 344 cancels a call registration when the entry / exit detection unit 341 deletes a user registered in the user table 3431 and there are no other user registrations corresponding to that user's call registration. For example, this is the case when a user who has registered an up call exits and the user registration is deleted, resulting in no user registrations corresponding to the call registration of the exiting user, i.e., no up user registrations. When canceling a call registration, a call request cancellation is sent to the elevator control device 20, and the up / down lamp 32a, up button 311a, or down button 311b is turned off.

[0029] The operation response unit 345 registers or resets the user table 3431 in response to the operation of the hall button 311 by the user and the arrival of the car.

[0030] Next, the control of hall call registration in the first embodiment will be described based on the control flowcharts in Figures 5, 6, and 7. Note that Figure 6 shows the case of an inbound train, and Figure 7 shows the case of an outbound train, and the processing content is the same for both trains except for the direction.

[0031] In FIG. 5, when the hall button 311 is pressed (step S001), the operation unit 31 determines whether the button is the up button 311a or the down button 311b (step S002). If the button is the up button 311a, an up call process is performed (step S100), and if the button is the down button 311b, a down call process is performed (step S200).

[0032] FIG. 6 is a flowchart showing step S100 of the inbound call processing. First, the operation unit 31 transmits an up call request to the elevator control device 20 (step S101). Next, in response to the pressing of the up button 311a, the operation response unit 345 assigns a user identifier to the person who pressed the up button 311a and registers them in the user table 3431. In Fig. 4, this corresponds to direction: up, user identifier: A, and reason for determination: operation.

[0033] Next, the operation response unit 345 determines whether the up car 1 has arrived at the hall (step S103). If it has arrived, the up car in the user table 3431 is reset (step S104), and the process ends.

[0034] If no one has arrived, the entry / exit detection unit 341 determines whether or not a person has entered based on the video captured by the camera 33a (step S105). If it is determined that a person has entered, the determination unit 342 determines whether the person who entered has an intention to use the facility, i.e., whether or not the person is a user (step S106). As already explained, this method is performed by analyzing the video to identify the body orientation and the position of both eyes. If it is determined that the person has an intention to use the facility, the determination unit 342 assigns a user identifier to the person who entered and registers the user in the user table 3431. In FIG. 4, this corresponds to direction: up, user identifier: B, and reason for determination: action.

[0035] Next, the entry / exit detection unit 341 determines whether any person has exited based on the video captured by the camera 33a (step S108). The entry / exit detection unit 341 identifies and monitors users by their user identifiers in the video. If the user disappears from the video, it is determined that the user has exited. In this case, the entry / exit detection unit 341 deletes the entry corresponding to the exiting user from the user table 3431 (step S109).

[0036] Next, the call cancellation unit 344 determines whether there are any upbound users registered in the user table 3431 (step S110), and if there are no registrations, cancels the upbound call registration (step S111) and ends the process. As a result, car 1 will not arrive at this hall. Steps S105 to S110 are repeated until an up car arrives.

[0037] In Fig. 5, if it is determined in step S002 that the down button 311b has not been pressed, a down call process is performed (step S200). Fig. 7 is a flowchart showing the down call process, but the flow is the same as the flowchart showing the up call process in Fig. 6.

[0038] Next, the processing will be specifically described based on an actual example. Figures 8 to 11 are diagrams showing images captured by the camera 33a of the hall monitoring unit 33 and the registration status of the user table 3431 in a specific example.

[0039] In Fig. 8, state (1) is when a person comes to the hall 11 and presses the up button 311a. In this case, steps S001 to S002 in Fig. 5 and steps S101 to S102 in Fig. 6 are performed. A person is shown in the image, and is registered in the user table 3431 with direction: up, user identifier: A, and reason for determination: operation. For convenience, the image shows "A", but a person is actually shown in the image.

[0040] In the state (1), two new people enter the hall 11 before the car 1 arrives. These people do not press the down button 311b. One of them is determined to be a user based on the direction of his body and the position of his eyes. The other person (referred to as α for convenience) simply leaves his room to check his email on his mobile phone, enters the hall 11, and stops to operate his mobile phone. Naturally, he is not interested in the up / down lamp 32a, the up button 311a, or the down button 311b. Therefore, based on the direction of his body and the position of his eyes, he is determined to have no intention of using the elevator, that is, he is not a user. In FIG. 6, steps S105 to S107 are performed. The state changes to (2), and the video shows three people, users A and B and the other person α, and the following information is registered in the user table 3431: direction: up, user identifier: B, and reason for determination: action.

[0041] In the state (2), a new person enters the hall 11 before the car 1 arrives, and this person presses the down button 311b. In this case, steps S001 to S002 in FIG. 5 and steps S201 to S202 in FIG. 7 are performed. The state becomes as shown in FIG. 9 (3), and the image shows four people, users A, B, C, and one other person α, and the user table 3431 registers the direction: down, user identifier: C, and reason for determination: operation. In this state, two processes, the up call process in FIG. 6 and the down call process in FIG. 7, are performed in parallel. In step S106 in FIG. 6, the down button 311b is pressed, so the person is not determined to be an up user.

[0042] In the state (3), before car 1 arrives, user A, who was at hall 11 and had registered an up call, exits hall 11. In this case, steps S108 to S110 in FIG. 6 are performed. The state changes to FIG. 9 (4), and the image shows three people: users B and C and another person α, and the user table 3431 has deleted the information "direction: up," "user identifier: A," and "reason for determination: operation." In this state, the user table 3431 still has the information "direction: up," "user identifier: B," and "reason for determination: operation" registered, so the up call continues.

[0043] In the state (4), user B, who was at hall 11, exits hall 11 before car 1 arrives. In Figure 6, steps S108 to S111 are performed. The state becomes as shown in Figure 10 (5-1), and the image shows two people, user C and another person α, and the direction: up, user identifier: B, and reason for determination: action are deleted from the user table 3431, and no registration is made. The call cancellation unit 344 cancels the up call registration, and only the down call continues.

[0044] Also, in state (4), a new person enters hall 11 before car 1 arrives. Up button 311a and down button 311b have already been pressed and are lit. This person is determined to be a user based on the orientation of their body and the position of their eyes. In this case, steps S105 to S107 are performed in FIG. 6, and steps S205 to S207 are performed in FIG. 7. The state becomes as shown in FIG. 10 (5-2), and four people, users B, C, and D and another person α, are displayed in the image. In user table 3431, direction: up, user identifier: D, reason for determination: action, and direction: down, user identifier: D, reason for determination: action are registered. Since determination unit 342 cannot determine whether the user wants to go up or down based on the action alone, both are registered.

[0045] In the state (5-2), user B, who was at hall 11, exits the hall before car 1 arrives. In Figure 6, steps S108 to S110 are performed. The state changes to Figure 11 (6), and the image shows three people: users C and D and another person, α, and the direction: up, user identifier: B, and reason for determination: action have been deleted from user table 3431. However, the registration of direction: up, user identifier: D, and reason for determination: action remains, so upbound calls continue.

[0046] In the state (6), an upbound car 1 arrives and user D gets on car 1. In this case, steps S103 to S104 are performed in FIG. 6. The state changes to FIG. 11 (7), and the image shows two people, user C and another person α, and all registrations for direction: up in user table 3431 are reset. However, downbound calls continue. If user D had the intention of going downstairs, then no one would board the upstairs car 1 that had arrived, and all of the above registrations would be reset.

[0047] In this way, in the first embodiment, after a person operates the operation unit 31 at a platform and registers a call, it is determined whether the person who arrives at the platform is a user based on their behavior, and it is determined whether to maintain the registration even after the user who operated the operation leaves the platform. This reduces the number of cars arriving at platforms where there are no users who have registered a call, thereby improving operation efficiency.

[0048] The determination unit 342 identifies the direction in which the person's body is facing and uses the position of both eyes, but it may also take into account the trajectory and movement speed after entering the imaging range of the hall, etc.

[0049] The determination unit 342 may also determine whether or not a person is a user by detecting the luggage and its size. If a person is at the elevator hall carrying large luggage, it can be assumed that the person intends to use the elevator.

[0050] Furthermore, the determination unit 342 may be linked to a door sensor entering the facility, and if it detects large luggage, a bed, or the like at the entrance, it may determine that the person carrying it is a user. This is because a person may wait a little distance away from the narrow platform until the car arrives, and then carry the luggage to the platform and the car after the car has arrived.

[0051] In FIG. 3, the hall monitoring unit 33 uses a camera 33a to detect people, but it may also use a distance measuring sensor, for example. Even with a distance measuring sensor, it is possible to infer the intention to board from the body orientation and line of sight based on the measured data. An ultrasonic sensor may also be used. Using ultrasonic waves, it is possible to detect the movement of a person from the reflected sound, confirm the direction the person is facing, and infer the intention to use the vehicle. The detection range of the distance measuring sensor and ultrasonic sensor can be set based on the strength of the radio waves and sound waves.

[0052] In addition, when the up button 311a is pressed and an up call is registered, and a person who wants to go down enters the platform, the judgment unit 342 may register a down call based on the action, based on the image from the camera 33a.

[0053] Normally, when a person who has entered the hall 11 approaches the hall button 311 with the upper of the up and down lamps 32a lit and the up button 311a lit, it is assumed that they are trying to press the down button 311b. Therefore, the approaching person is determined to be a passenger going down and a call for the down button is registered. This allows the car 1 to arrive at the hall earlier.

[0054] 1 and 3, the car 1 is described as one unit, but it is of course also possible to simultaneously control multiple cars 1. In this case, the elevator control device 20 corresponds to the multiple cars 1 and controls multiple hoists 4. The order of arrival differs between the ascending car 1 and the descending car 1, and the hall control device 30 can optimally control the order.

[0055] 12 is a diagram showing an example of hardware resources of the call control unit 34. The call control unit 34 includes a processor 34a and a memory 34b as hardware resources. The memory 34b is a type of storage medium. Note that there may be multiple processors 34a and multiple memories 34b.

[0056] The memory 34b functions as the storage unit 343 of the call control unit 34. The memory 34b also stores programs that are read out as needed and executed by the processor 34a, thereby fulfilling the functions of an entry / exit detection unit 341, a determination unit 342, a call cancellation unit 344, and an operation response unit 345.

[0057] The processor 34a is also called a CPU (Central Processing Unit), central processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 34b may be a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD. Usable semiconductor memory includes RAM, ROM, flash memory, EPROM, EEPROM, etc.

[0058] Fig. 13 is a diagram showing another example of hardware resources of the call control unit 34. In the example of Fig. 13, the call control unit 34 includes a processing circuit including a processor 34a, a memory 34b, and dedicated hardware 34c. Some of the functions of the call control unit 34 are realized by the dedicated hardware 34c. It is also possible to realize all of the functions of the call control unit 34 by the dedicated hardware 34c. The dedicated hardware 34c can be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.

[0059] Embodiment 2 The determination unit 342 may use AI technology to determine the user. FIG. 14 is a configuration diagram of the determination unit 342 in the second embodiment, which is mainly composed of a trained model 342a and an inference unit 342b.

[0060] The trained model 342a holds a large amount of video data of the movements of people who intend to use the platform and enter the platform with the platform button 311 pressed. The inference unit 342b then compares the video of the movements of the person entering the platform, captured by the camera 33a, with the video data of the trained model 342a, and, based on the similarity, infers whether the person intends to use the platform and identifies the user.

[0061] In this way, the accuracy of judgment can be improved by using AI technology.

[0062] Embodiment 3 If a new person enters while the up button 311a and the down button 311b are already pressed, it is difficult to determine whether the person wants to go up or down, even if the intention to use the facility can be guessed. For this reason, in the first embodiment, the up and down buttons are registered separately, as in state (5-2) D in Fig. 10, and the call is not canceled even when only D remains in the up user table 3431, as in state (6) in Fig. 11.

[0063] In contrast to this, in the third embodiment, confirmation is made with people at the boarding area. FIG. 15 is a diagram showing an image captured by the camera 33a and the registration status of the user table 3431 in a specific example.

[0064] The state (5-3) in Figure 15 corresponds to the state (5-2) in Figure 10, and shows the case in which a new person enters hall 11 before car 1 arrives in the state of Figure 9 (4). This person intends to use the elevator, but the direction is unknown, so the state is registered as shown in Figure 15 (5-3), with direction: unknown, user identifier: D, and reason for determination: action.

[0065] FIG. 16 is a flowchart showing the inbound call processing, particularly step S110, according to the third embodiment.

[0066] 16, after deleting the registration corresponding to the withdrawn user from user table 3431 in step S109 in Fig. 6, call cancellation unit 344 determines whether there is a user registration with the above destination in user table 3431 (step S110a). If there is no registration, it determines whether there is a user registration with an unknown destination (step S110b).

[0067] If there is a registered user whose destination is unknown, a notification is sent to the person at the hall 11 to urge them to take action (step S110c). Specifically, the up button 311a is changed from lit to flashing. At the same time, a voice generation unit that issues voice notifications to the hall 11 issues a voice announcement urging the person at the hall 11 to operate the up button 311a, saying, "If you are going up, please press the up button."

[0068] Thereafter, it is checked for several seconds whether there is a response (step S110d), and if a user who has registered an unknown destination presses the up button 311a, the direction is rewritten to up in the user's registration (step S110e), and the process returns to step S103.

[0069] If a user who has registered an unknown destination does not press the up button 311a, that user will be considered to be someone who wants to go down. Therefore, the registered destination is rewritten from unknown to down (step S110f), and the process proceeds to step S111.

[0070] In the state of Figure 15 (5-3), user B, who was at hall 11, exited hall 11 before car 1 arrived. In this case, a notification was made in S110c of the flowchart in Figure 16, and user D pressed the up button 311a. As a result, the state becomes as shown in Figure 15 (6-1), and the registration of direction: up, user identifier: D, and reason for determination: action remains in user table 3431, so the up call will continue.

[0071] By doing so, it is possible to further reduce unnecessary cage calls.

[0072] Although the preferred embodiments have been described in detail above, the present invention is not limited to these embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the disclosure.
