Description

Elevator System, Call Control Method, Landing Control Device, and Call Program

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

[0002] After registering a call by pressing a landing button in the elevator landing, a user may stop using the elevator and use a staircase, an escalator, or the like. In such a case, if the call registration remains, the car arrives at the landing and the door opens. This reduces the operating efficiency of the elevator and also gives discomfort to the passengers.

[0003] Therefore, in Patent Document 1, when the detection unit detects that there is no person in the landing after a user operates the landing button to register a call and before the car arrives, the call registration is canceled.

[0004] Japanese Patent Application Laid-Open No. 2015-113179

[0005] In the elevator described in Patent Document 1, even if the user who operated the landing button leaves the landing after choosing the staircase, the call registration is maintained if there is another person in the landing. However, this person in the landing may simply pass through the landing or be on the phone in the landing without the intention of boarding. Nevertheless, if the car arrives and the door is opened, the operating efficiency is reduced.

[0006] The present disclosure has been made to solve the above problems, and an object thereof is to provide an elevator control system that appropriately maintains or cancels call registration by inferring the intention of use of the people in the landing after the person who registered the call using the landing button has left the landing.

[0007] The elevator system disclosed herein includes a landing monitoring unit with a specific detection range at the landing, an operating unit that accepts call registrations from users at the landing, an elevator control unit that controls the operation of the elevator car based on the call registration, an announcement unit that notifies the call registered by the operating unit, and a call control unit that, when a person enters the detection range while a call registration is in place, determines whether the person is a user based on their actions and registers them as a user. The call control unit maintains the call registration if a user who has registered a call with the operating unit leaves the detection range, and cancels the call registration if another user corresponding to the user who left has been registered.

[0008] According to this disclosure, after a person who has registered to call using the boarding button leaves the boarding area, the registration can be properly maintained or canceled, thereby improving operational efficiency.

[0010] The embodiments for implementing this disclosure will be described with reference to the attached drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals, and redundant explanations are simplified or omitted as appropriate.

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

[0012] A machine room 3 is located directly above the elevator shaft 2. The machine room 3 houses a hoisting machine 4, a hoisting machine control panel 5, a deflection wheel 6, and an elevator control device 20.

[0013] The cage 1 and the counterweight 7 are each connected to the ends of the rope 8. The rope 8 is hung over the hoisting machine 4 and the deflection wheel 6, and the cage 1 and the counterweight 7 are suspended from it.

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

[0015] On each floor, a landing 11 is located in front of the landing door 10 for boarding the elevator car 1. When elevator car 1 arrives on each floor, the landing door 10 opens in conjunction with the opening of the elevator car door 9 by the drive motor, allowing passengers at the landing 11 to board elevator car 1.

[0016] Each landing 11 is equipped with a landing control device 30. This landing control device 30 is connected to the elevator control device 20 by a communication line 12, enabling them to send and receive information from each other.

[0017] Figures 2 and 3 show a schematic diagram of the landing control device 30; Figure 2 is a configuration diagram, and Figure 3 is a layout diagram at the landing.

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

[0019] The control unit 31 is located near the landing door 10 and includes landing buttons 311 installed on the wall of the landing 11. The landing buttons 311 include an up button 311a to press when going up and a down button 311b to press when going down. When a user presses these buttons, a call registration is performed. That is, for example, when the up button 311a is pressed, a call request is sent to the elevator control device 20 to bring the car 1 to the landing in the upward direction. The elevator control device 20 accepts the request, and the hoisting machine control panel 5 controls the drive of the hoisting machine 4 to bring the car 1 to the landing 11. The up button 311a and down button 311b also have light-emitting elements inside, and when pressed by a user, they light up until the car 1 in that direction arrives at the landing 11.

[0020] The notification unit 32 consists of an up / down lamp 32a that indicates the direction of the elevator car 1 and a display panel 32b that indicates the current position of the elevator car 1. The up / down lamp 32a indicates whether the elevator car 1 arriving at the landing 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 upward direction lights up.

[0021] The landing monitoring unit 33 is equipped with a camera 33a that is installed on the wall 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 people from the video footage captured by the camera 33a and analyzes their movements. This allows it to detect whether a new person has entered the shooting range of the boarding area 11, or whether a person has exited the shooting range.

[0023] The memory unit 343 has a user table 3431, as shown in Figure 4, which represents the users of the elevator car 1. The user table 3431 is divided into an uphill user table and a downhill user table. Each table also has columns for direction, user identifier, and reason for identification. The user identifier is an identifier arbitrarily assigned sequentially to each person who becomes a user. The entry / exit detection unit 341 deletes the registration of a user registered in the user table 3431 when that user exits the shooting range of the landing 11.

[0024] The determination unit 342 determines whether to register a person in the user table 3431 when the entry / exit detection unit 341 detects that the person has entered the shooting range of the landing 11. In other words, it infers from the actions of the person who has just entered the shooting range whether they intend to use the elevator, and if it is determined that they do, it registers them in the user table 3431.

[0025] Normally, when someone wants to use the elevator, they go to landing 11 and check if a call registration has been made, that is, if someone has already pressed the landing button 311 for the direction they want to go. If no one has pressed it, they press the landing button 311 themselves to register their call.

[0026] This confirmation is performed by visually checking the up / down lamps 32a, or the up button 311a and down button 311b. If the up button 311a and down button 311b have already been pressed, these buttons will light up, and if they are registered as calls, the up / down lamps 32a will light up.

[0027] Therefore, here, we infer whether a person who has entered has performed an action to confirm their presence from their gaze and body orientation. Specifically, first, we analyze the video to determine the direction the person's body is facing and to identify the position of each eye. Then, we determine that the person's body is facing the wall where the landing door 10 is located. Furthermore, the up / down lamps 32a, or the up button 311a and down button 311b, are located on a vertical line extending perpendicularly from the center of the line connecting those two eyes. If this state continues for 2 seconds, we can infer that the person intends to use the facility and register them in the user table 3431.

[0028] The call cancellation unit 344 cancels a call registration if the user registered in the user table 3431 is deleted by the entry / exit detection unit 341, and there are no other user registrations corresponding to that user's call registration. For example, this occurs when a user who had registered an up-route call exits and their user registration is deleted, resulting in zero user registrations corresponding to the exiting user's call registration, i.e., up-route user registrations. When a call registration is canceled, the cancellation of the call request is transmitted to the elevator control device 20, and the up / down lamps 32a, up button 311a, or down button 311b are turned off.

[0029] The operation response unit 345 responds to user operation of the boarding button 311 and the arrival of the elevator car, and registers or resets the user table 3431.

[0030] Next, the control of the landing call registration in Embodiment 1 will be explained based on the control flowcharts in Figures 5, 6, and 7. Note that Figure 6 shows the case for going up and Figure 7 shows the case for going down, but the processing content is the same, only the direction changes.

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

[0032] Figure 6 is a flowchart of step S100, which is the process for calling an elevator to go up. First, the operation unit 31 sends an elevator call request to the elevator control device 20 (step S101). Next, the operation response unit 345 receives notification that the up button 311a has been pressed and registers the person who pressed the up button 311a in the user table 3431, assigning a user identifier to that person. In Figure 4, this corresponds to direction: up, user identifier: A, identification reason: operation.

[0033] Next, the operation response unit 345 determines whether the ascending elevator car 1 has arrived at the landing (step S103). If it has arrived, it resets the ascending entry in the user table 3431 (step S104) and terminates the process.

[0034] If no one has arrived, the entry / exit detection unit 341 determines whether someone has entered based on the video footage captured by the camera 33a (step S105). If it determines that someone has entered, the determination unit 342 determines whether the person has the intention to use the facility, i.e., whether they are a user (step S106). As previously explained, this method is performed by analyzing the video footage to identify the body orientation and the position of both eyes. If the determination unit 342 determines that the person has the intention to use the facility, it assigns a user identifier to the person who entered and registers them in the user table 3431. In Figure 4, this corresponds to direction: up, user identifier: B, and determination reason: action.

[0035] Next, the entry / exit detection unit 341 determines whether someone has exited based on the video footage captured by the camera 33a (step S108). The entry / exit detection unit 341 identifies and monitors users using user identifiers in the video footage. If a user disappears from the video footage, it determines that they have 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 checks the user table 3431 to see if there are any registered users for an upward ride (step S110). If there are no registered users, it cancels the upward call registration (step S111) and terminates the process. As a result, car 1 will not arrive at this landing. Steps S105 through S110 are repeated until an upward car arrives.

[0037] In Figure 5, if it is determined in step S002 that the down button 311b has been pressed, the down call process is performed (step S200). Figure 7 is a flowchart of the down call process, but the flow is the same as the flowchart showing the up call process in Figure 6.

[0038] Next, we will explain the process in detail based on actual examples. Figures 8 to 11 show the video footage captured by the camera 33a of the boarding area monitoring unit 33 and the registration status in the user table 3431 in a specific example.

[0039] In Figure 8, state (1) is when a person arrives at the landing 11 and presses the up button 311a. In this case, steps S001 to S002 in Figure 5 and steps S101 to S102 in Figure 6 are performed. The video shows a person, and the user table 3431 registers the direction as up, user identifier as A, and reason for identification as operation. For convenience, the diagram shows "A", but the actual video shows a person.

[0040] In state (1), two more people entered the landing 11 before the elevator car 1 arrived. These people did not press the down button 311b. One person was determined to be a user based on their body orientation and the position of their eyes. The other person (let's call them α for convenience) simply left their room, entered the landing 11, and stopped to operate their mobile phone, for example, to check their emails. Naturally, they had no interest in the up / down lamps 32a, or the up button 311a, or down button 311b. Therefore, based on their body orientation and the position of their eyes, they were determined not to intend to use the elevator, i.e., not to be a user. In Figure 6, steps S105 to S107 are performed. In state (2), the video shows users A and B, and the other person α, and the user table 3431 registers: direction: up, user identifier: B, reason for determination: action.

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

[0042] In the state of (3), before the car 1 arrives, user A who had registered an upward call and was at the landing 11 exits from the landing 11. In this case, steps S108 to S110 in FIG. 6 are performed. It becomes the state of FIG. 9(4), and in the video, users B and C and three other people α are shown. In the user table 3431, the direction: up, user identifier: A, discrimination reason: operation, is deleted. In this state, since the direction: up, user identifier: B, discrimination reason: movement, is registered in the user table 3431, the upward call continues.

[0043] In the state of (4), before the car 1 arrives, user B who was at the landing 11 exits from the landing 11. In FIG. 6, steps S108 to S111 are performed. It becomes the state of FIG. 10(5-1), and in the video, user C and two other people α are shown. In the user table 3431, the direction: up, user identifier: B, discrimination reason: movement, is deleted and there is no registration. The call cancellation unit 344 cancels the upward call registration, and only the downward call continues.

[0044] Also, in the state of (4), before the car 1 arrives, a new person enters the landing 11. Already, the up button 311a and the down button 311b have been pressed and are lit. And this person is determined to be a user from the body orientation and the positions of both eyes. In this case, in FIG. 6, steps S105 to S107 are performed, and in FIG. 7, steps S205 to S207 are performed. It becomes the state of FIG. 10(5-2), and in the video, users B, C, D and four other people α are shown. In the user table 3431, the direction: up, user identifier: D, discrimination reason: movement, and the direction: down, user identifier: D, discrimination reason: movement, are registered. In the determination unit 342, only by the movement, it cannot be discriminated whether the user wants to go up or down, so both are registered.

[0045] In the state of (5-2), before the car 1 arrives, user B who was at the landing 11 exits the landing. In FIG. 6, steps S108 to S110 are performed. It becomes the state of FIG. 11(6), and in the video, users C and D and three other people α are shown, and on the user table 3431, direction: up, user identifier: B, discrimination reason: movement, are deleted. However, since the registration of direction: up, user identifier: D, discrimination reason: movement, remains, the upward call continues.

[0046] In the state of (6), the upward car 1 arrives and user D gets on the car 1. In this case, in FIG. 6, steps S103 to S104 are performed. It becomes the state of FIG. 11(7), and in the video, user C and two other people α are shown, and all the registrations of direction: up on the user table 3431 are reset. However, the downward call continues. Incidentally, if user D had the intention to go down, the arriving upward car 1 would not be boarded by anyone, and all the registrations above would be reset.

[0047] Thus, in the first embodiment, at the landing, after operating the operation unit 31 to perform call registration, it is determined whether a person who has come to the landing is a user based on the behavior of the person who has come to the landing, and even after the user who has operated has exited the landing, it is determined whether to maintain the registration. As a result, it is possible to reduce the arrival of the car at the landing where there is no user who has performed call registration at the landing, and improve the operation efficiency.

[0048] Note that the determination unit 342 specifies the direction in which the person's body is facing and uses the positions of both eyes, but in addition, it may make a determination in consideration of the trajectory and moving speed after entering the shooting range of the landing, etc.

[0049] Further, the determination unit 342 may detect the luggage carried and its size and determine whether it is a user. A person who is at the landing with a large luggage can be presumed to have the intention of using the elevator.

[0050] Further, the determination unit 342 may be interlocked with the door sensor for entering the facility, and when detecting a large luggage, a bed, etc. at the entrance, it may determine that the person carrying it is a user. This is because until the car arrives, the person may wait a little away from the narrow landing, and after the car arrives, carry the luggage to the landing and the car.

[0051] In Figure 3, the boarding area monitoring unit 33 uses a camera 33a to detect people, but for example, a distance measuring sensor may also be used. Even with a distance measuring sensor, the intention to board can be inferred from the body orientation and gaze direction based on the measured data. Alternatively, an ultrasonic sensor may also be used. By using ultrasound, the movement of a person can be detected from the reflected sound, the direction they are facing can be confirmed, and their intention to use the service can be inferred. The detection range for the distance measuring sensor and ultrasonic sensor can be set based on the intensity of radio waves and sound waves, respectively.

[0052] Furthermore, if the up button 311a is pressed and an up call registration has been made, and a person who wants to go down enters the landing, the determination unit 342 may, based on the image from the camera 33a, register a down call based on that person's actions.

[0053] Normally, when a person enters the boarding area 11, the upper of the upper and lower lamps 32a is lit, and the upper button 311a is lit, it is presumed that they approach the boarding area button 311 to press the lower button 311b. Therefore, the approaching person is identified as a disembarking passenger, and the lower call registration is made. This allows the elevator car 1 to arrive at the boarding area more quickly.

[0054] In Figures 1 and 3, the elevator car 1 is described as a single unit, but it is certainly possible to control multiple cars 1 simultaneously. In this case, the elevator control device 20 will control multiple hoisting machines 4 to accommodate multiple cars 1. Unlike the ascending and descending cars 1, the order of arrival will vary, but the landing control device 30 can control them optimally.

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

[0056] The memory 34b is responsible for the storage unit 343 of the call control unit 34. The memory 34b also stores a program, which is read as needed and executed by the processor 34a, performing the functions of the entry / exit detection unit 341, the determination unit 342, the call cancellation unit 344, and the 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, magnetic disk, flexible disk, optical disk, compact disk, minidisc, or DVD. Possible semiconductor memories include RAM, ROM, flash memory, EPROM, and EEPROM.

[0058] Figure 13 shows another example of hardware resources for the call control unit 34. In the example in Figure 13, the call control unit 34 includes a processing circuit that includes a processor 34a, memory 34b, and dedicated hardware 34c. Some of the functions of the call control unit 34 are realized by the dedicated hardware 34c. Alternatively, all of the functions of the call control unit 34 may be realized 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 thereof.

[0059] Embodiment 2. AI technology may be used in the determination of the user by the determination unit 342. Figure 14 is a configuration diagram of the determination unit 342 in Embodiment 2, which mainly consists 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 a person who intends to use the elevator and enters the elevator platform with the boarding button 311 pressed. The inference unit 342b then compares the video of the person's movements captured by camera 33a with the video data from the trained model 342a, infers whether or not the person intends to use the elevator based on the similarity, and determines whether or not the person is a user.

[0061] In this way, AI technology can be used to improve the accuracy of the judgment.

[0062] Embodiment 3. When the upper button 311a and lower button 311b are already pressed, and a new person enters, even if their intention to use the facilities can be inferred, it is difficult to determine whether they want to go up or down. Therefore, in Embodiment 1, as shown in state D in Figure 10 (5-2), the upper and lower buttons are registered separately, and the call is not canceled even if only D remains in the upper user table 3431, as shown in state 6 in Figure 11.

[0063] In contrast, in Embodiment 3, confirmation is made to a person at the boarding area. Figure 15 shows the video captured by camera 33a and the registration status in user table 3431 in a specific example.

[0064] The state in Figure 15 (5-3) corresponds to the state in Figure 10 (5-2), and shows the case in Figure 9 (4) where a new person enters the landing 11 before the elevator car 1 arrives. This person intends to use the elevator, but the direction is unknown, so they are registered as follows, as in the state in Figure 15 (5-3): Direction: Unknown, User Identifier: D, Reason for Identification: Action.

[0065] Figure 16 is a flowchart showing the upstream call processing in Embodiment 3, specifically the portion of step S110.

[0066] In Figure 16, after deleting the entry corresponding to the exiting user from the user table 3431 in step S109 of Figure 6, the call cancellation unit 344 determines whether there is a user entry with the destination listed above in the user table 3431 (step S110a). If there is no such entry, it determines whether there is a user entry 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 boarding area 11 prompting them to take action (step S110c). Specifically, the upper button 311a is changed from steady on to blinking. At the same time, the voice generator that notifies boarding area 11 by voice makes a voice announcement prompting the operation of the upper button 311a, saying, "If you are going up, please press the upper button."

[0068] After that, the system checks for a few seconds to see if there is a response (step S110d). If a user registered as having an unknown destination presses the up button 311a, the direction is rewritten to "up" in that user's registration (step S110e), and the system returns to step S103.

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

[0070] In the state shown in Figure 15 (5-3), before elevator car 1 arrived, user B, who was at landing 11, left landing 11. In this case, a notification is issued at S110c in the flowchart of Figure 16, and user D presses the up button 311a. As a result, the state shown in Figure 15 (6-1) is reached, and the user table 3431 retains a record with direction: up, user identifier: D, and reason for identification: action, so the up call will continue.

[0071] By doing so, unnecessary calls for carts can be further reduced.

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