Description

[Technical Field]

[0001] The present disclosure relates to elevator systems. [Background technology]

[0002] Patent Document 1 discloses an elevator system. In this elevator system, when a mobile terminal carried by a user receives radio waves from a hall beacon installed at the hall, the mobile terminal transmits a call request including the departure floor and destination floor indicating the hall. The control panel of the elevator system registers the call request in the car. Therefore, the user can register the departure floor and destination floor in the car simply by going to the hall with the mobile terminal. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-113125 Summary of the Invention [Problem to be solved by the invention]

[0004] However, after a call request is sent, the user may not immediately move to the waiting position at the landing because they stop by a mailbox, they are moving slowly, etc. For this reason, there is a risk that unnecessary calls for the car will occur in the elevator system described in Patent Document 1.

[0005] The present disclosure has been made to solve the above-mentioned problems. An object of the present disclosure is to provide an elevator system that suppresses a decrease in elevator utilization efficiency and allows a user to call a car without operating a mobile device. [Means for solving the problem]

[0006] The elevator system according to the present disclosure includes: a hall beacon provided at an elevator hall and emitting hall radio waves; a control device that, when a call including a designated time is received, controls the operation of the elevator car so that the elevator car arrives at the departure floor at the designated time; a mobile terminal carried by a user and that transmits a call request including the departure floor and the destination floor when the reception strength of the hall radio waves exceeds a first threshold; and a server device that receives the call request from the mobile terminal and transmits a call based on the call request to the control device, and the mobile terminal controls the user to wait at the hall when the reception strength of the hall radio waves exceeds a second threshold that is greater than the first threshold. The server device determines that the user has arrived at the waiting position, and the server device has: a first prediction unit that, when receiving a call request from the mobile terminal, estimates a first predicted time that is the time that the user will arrive at the waiting position based on a first prediction model and that is associated with the mobile terminal and the control device; a call control unit that transmits a call based on the call request and that includes the first predicted time as a specified time to the control device; an actual result calculation unit that calculates a waiting time that is the difference between the time when the mobile terminal determines that the user has arrived at the waiting position and the time when the car stops at the platform; and a first update unit that updates the first prediction model based on the waiting time calculated by the actual result calculation unit. [Effects of the Invention]

[0007] According to the present disclosure, a mobile device transmits a call request when the reception strength of the hall radio wave exceeds a first threshold. This allows a user to call a car without operating the mobile device. Furthermore, upon receiving the call request, the server device transmits a call to the control device with a first predicted time as the designated time based on the first prediction model. The first prediction model is updated based on the actual waiting time determined by the mobile device. This prevents a decrease in elevator utilization efficiency.

[0009] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. Duplicate descriptions of these parts will be appropriately simplified or omitted.

[0010] Embodiment 1 Fig. 1 is a schematic diagram of a building provided with an elevator system according to embodiment 1. Fig. 2 is a schematic diagram of a hall of the elevator system according to embodiment 1.

[0011] In the elevator system 1 of Figures 1 and 2, a hoistway 2 passes through each floor of a building 3. A plurality of landings 4 are provided on each floor of the building 3. The landings 4 are part of the space on each floor of the building 3. Each of the plurality of landings 4 faces the hoistway 2. An entrance is provided between the landing 4 and the hoistway 2. A landing door 5 is provided at the entrance of each of the plurality of landings 4.

[0012] The hoisting machine 6 is provided in a machine room above the hoistway 2. A main rope 7 is wound around the hoisting machine 6. The car 8 is suspended from the main rope 7 inside the hoistway 2. The car 8 can move up and down inside the hoistway 2 by following the main rope 7 moved by the hoisting machine 6. A car door 9 is provided on the side of the car 8 facing the landing 4. The control device 10 is provided in the machine room. The control device 10 is capable of controlling operations related to the operation of the car 8. The control device 10 may be a control panel for the car 8, or may be a group control device that group-controls the operation of multiple cars (not shown) including the car 8.

[0013] The elevator system 1 further includes a plurality of hall beacons 11, a car beacon 12, a server device 20, and a mobile terminal 30.

[0014] The multiple hall beacons 11 are provided at some of the multiple halls 4. The hall beacons 11 transmit hall radio waves including an identifier specific to the floor of the hall 4. The hall beacons 11 may be provided at all of the halls 4, or may be provided at only specific halls 4 among the multiple halls 4.

[0015] The car beacon 12 is provided in the car 8. The car beacon 12 transmits a car radio wave including an identifier unique to the car 8.

[0016] The server device 20 is provided in a building separate from the building 3. The server device 20 is capable of communicating with the control device 10 via a network N.

[0017] The mobile terminal 30 is a device capable of displaying information and accepting input of information. For example, the mobile terminal 30 is a smartphone. The mobile terminal 30 is carried by a user of the elevator system 1. The mobile terminal 30 is capable of communicating with the server device 20 via the network N. The mobile terminal 30 is capable of receiving hall radio waves and car radio waves. The mobile terminal 30 stores a dedicated application that can be used in the elevator system 1. At least some of the functions of the mobile terminal 30 are realized by executing the dedicated application.

[0018] The mobile terminal 30 stores in advance information on combinations of departure floors and destination floors in the building 3. In the following, it is assumed that the mobile terminal 30 is set to an automatic call mode.

[0019] At the departure floor, as the user approaches hall 4, the reception strength of the hall radio waves received by mobile terminal 30 gradually increases. When the reception strength of the hall radio waves exceeds a preset first threshold, mobile terminal 30 transmits a call request including the departure floor and the destination floor to server device 20 as a process defined in the automatic call mode. At this time, the user does not operate mobile terminal 30.

[0020] After a call request is transmitted, the passenger may not immediately move to the waiting position at the landing 4, i.e., in front of the landing door 5. For this reason, if the car 8 heads toward the landing 4 immediately after the call request is transmitted, there is a risk that the car 8 will move from the departure floor indicated in the call request to the destination floor without picking up the passenger.

[0021] As an example, if building 3 is an apartment building and hall 4 is an entrance floor, mobile terminal 30 may transmit a call request when a user passes through the entrance to the entrance floor. For example, after passing through the entrance, the user checks the mailbox and then moves to the waiting position at hall 4. In this case, if car 8 heads toward hall 4 immediately after the call request is transmitted, there is a risk that car 8 will depart for the destination floor indicated in the call request without the user being able to board car 8.

[0022] As another example, if building 3 is an office building and hall 4 is an entrance floor, mobile terminal 30 may transmit a call request when passing through the entrance to the entrance floor. For example, after passing through the entrance, a user may complete entry procedures at reception and then move to a waiting position at hall 4. In this case, too, there is a risk that car 8 may depart for the destination floor before the user is able to board car 8.

[0023] Therefore, the server device 20 estimates a first predicted time corresponding to the mobile terminal 30 and the hall 4 based on the call request and the first prediction model. The first prediction model is a model for estimating the first predicted time. The server device 20 transmits a call corresponding to the call request, which includes the first predicted time as a specified time, to the control device 10.

[0024] When the control device 10 receives a call including a specified time, it registers the call in the car 8 so that the car 8 will stop at the departure floor at the specified time. In other words, the control device 10 controls the operation of the car 8 so that the car 8 arrives at the hall 4 at the first predicted time.

[0025] The mobile terminal 30 determines that the user has arrived at the waiting position of the platform 4 when the reception strength of the platform radio waves exceeds a second threshold value. The second threshold value is greater than the first threshold value. The mobile terminal 30 determines that the user has boarded the car 8 when the reception strength of the car radio waves exceeds a boarding threshold value. In this case, the mobile terminal 30 transmits information on the user's behavior to the server device 20.

[0026] The server device 20 updates the first prediction model based on the information on the behavior of the user so that the optimal first prediction time can be estimated.

[0027] Next, the function of each device in the elevator system 1 will be described with reference to FIG. FIG. 3 is a functional block diagram of the elevator system according to the first embodiment.

[0028] As shown in FIG. 3, the control device 10 has an operation control unit 10a as a function. The operation control unit 10a registers a received call in a car 8. When a received call includes a specified time and a departure floor, the operation control unit 10a registers the call in the car 8 so that the car 8 arrives at the departure floor at the specified time. At this time, the operation control unit 10a may directly control the operation of the car 8 based on the call. When the car 8 stops at the departure floor, the operation control unit 10a notifies the server device 20 of the actual stop time, which is the time when the car 8 stopped at the departure floor.

[0029] The mobile terminal 30 has as its functions a receiving unit 31, a call request unit 32, and a recording unit 33. The receiving unit 31 includes an antenna capable of receiving hall radio waves and car radio waves, and a function for controlling the antenna.

[0030] The call request unit 32 is a function realized by a dedicated application, and controls the operation of sending a call request. For example, when the automatic call mode is set and the reception strength of the hall radio waves received by the receiver 31 exceeds a first threshold, the call request unit 32 sends a call request including the departure floor and the destination floor to the server device 20. The call request includes at least a terminal ID that is an identifier of the mobile terminal 30, and a device ID that is an identifier of the control device 10 included in the hall radio waves. Note that the device ID may also include information about the floor of the hall 4.

[0031] The recording unit 33 records the fact that the radio wave reception strength exceeded a certain threshold and the time at which the strength exceeded the threshold, in association with the time, based on the radio waves received by the receiving unit 31. The recording unit 33 transmits the recorded information to the server device 20.

[0032] Specifically, when the reception strength of the hall radio waves exceeds a first threshold, the recording unit 33 records, as request information, the fact that the first threshold has been exceeded and the requested time at that time. When the reception strength of the hall radio waves received by the receiving unit 31 exceeds a second threshold, the recording unit 33 determines that the user has arrived at the waiting position of the hall 4, and records, as arrival record information, the fact that the second threshold has been exceeded and the actual arrival time at that time. When the reception strength of the car radio waves received by the receiving unit 31 exceeds a boarding threshold, the recording unit 33 records, as boarding record information, the fact that the boarding threshold has been exceeded and the actual boarding time at that time. After recording the boarding record information, the recording unit 33 transmits the arrival record information and boarding record information recorded immediately before to the server device 20 after associating them with the terminal ID and the device ID.

[0033] The server device 20 has as its functions a memory unit 21, a call control unit 22, a first prediction unit 23, a performance calculation unit 24, and a first update unit 25. The memory unit 21 stores a database of device IDs for a plurality of control devices and a plurality of cars installed in locations other than the building 3, terminal IDs for a plurality of mobile terminals other than the mobile terminal 30, etc. The memory unit 21 may store information previously received from the mobile terminal 30.

[0034] The call control unit 22 identifies, based on the device ID and terminal ID included in the call request, that the call request is related to the control device 10 of the building 3 and has been sent from the mobile terminal 30. The call control unit 22 sends to the control device 10 a call that indicates the departure floor and destination floor indicated in the call request and that includes the first predicted time estimated by the first prediction unit 23 as the designated time.

[0035] When the first prediction unit 23 receives a call request, it estimates a first predicted time based on the device ID and terminal ID included in the call request. At this time, the first prediction unit 23 estimates the first predicted time using a first prediction model. The first prediction model is a model for estimating the first predicted time, and outputs a first predicted time associated with the device ID and terminal ID based on the device ID and terminal ID. The first predicted time is associated with the device ID and terminal ID, i.e., the time that the mobile terminal 30 should wait when it transmits a call request in the building 3. The first prediction unit 23 estimates the time obtained by adding the first predicted time to the current time as the first predicted time.

[0036] The performance calculation unit 24 calculates the performance waiting time based on the performance information received from the mobile terminal 30 and the notification of the performance stopping time received from the control device 10. Specifically, the performance calculation unit 24 calculates the time from the performance arrival time received from the recording unit 33 to the performance stopping time received from the control device 10 as the performance waiting time.

[0037] Here, if the actual arrival time is later than the actual stop time, the actual result calculation unit 24 calculates the actual waiting time as a positive value, which is the absolute value of the time from the actual stop time to the actual arrival time.If the actual arrival time is earlier than the actual stop time, the actual result calculation unit 24 calculates the actual waiting time as a negative value, which is the absolute value of the time from the actual arrival time to the actual stop time.

[0038] The first update unit 25 updates the first prediction model based on the actual waiting time. Specifically, the first update unit 25 updates the first prediction model by changing the value of the first prediction time associated with the device ID and the terminal ID based on the actual waiting time associated with the device ID and the terminal ID.

[0039] The first updating unit 25 changes the value of the first predicted time so that the actual waiting time approaches 0. At this time, the first updating unit 25 changes the first predicted time within a range where the first predicted time does not become smaller than 0. Specifically, when the actual waiting time is positive, the first updating unit 25 changes the first predicted time so that the larger the value of the actual waiting time, the shorter the changed first predicted time becomes, with 0 being the minimum value. When the value of the actual waiting time is negative, the first updating unit 25 changes the first predicted time so that the smaller the actual waiting time, i.e., the larger the absolute value of the actual waiting time, the longer the changed first predicted time becomes.

[0040] As an example, the first update unit 25 calculates the product of the actual holding time and a specified first update coefficient, and calculates the difference by subtracting the product of the actual waiting time and the first update coefficient from the first predicted time before the change. The first update coefficient is a positive value. For example, when the first update coefficient is 1, the first update unit 25 calculates the difference by subtracting the actual holding time from the first predicted time before the change. When the first update coefficient is 0.5, the first update unit 25 calculates the difference by subtracting half of the actual holding time from the first predicted time before the change. When the difference is equal to or greater than 0, the first update unit 25 sets the difference as the changed first predicted time. When the difference is less than 0, the first update unit 25 sets the changed first predicted time to 0.

[0041] Next, the flow of operations performed in the elevator system 1 will be described with reference to FIG. FIG. 4 is a sequence diagram of an example of an operation performed in the elevator system according to the first embodiment.

[0042] The sequence in FIG. 4 starts, for example, when a user is moving near hall 4. Each operation performed in the sequence is described as a step. In FIG. 4, the equipment installed in building 3 of elevator system 1 is described as "elevator equipment." The vertical direction indicates time. In FIG. 4, the time increases as you move downwards. The time is described with time t, when the operation of step S001 is performed, as 0. The unit of time is seconds.

[0043] The mobile terminal 30 is in a moving state. In step S001, the mobile terminal 30 detects that the reception strength of the hall radio wave from the hall beacon 11 has exceeded a first threshold. Then, in step S002, the mobile terminal 30 transmits a call request to the server device 20. The call request includes the departure floor, the destination floor, the device ID, and the terminal ID.

[0044] Then, in step S003, the server device 20 estimates a first predicted time. Then, in step S004, the server device 20 transmits a call including the first predicted time as a specified time to the control device 10. The call further includes a departure floor and a destination floor.

[0045] Thereafter, in step S005, the control device 10 receives a call. The control device 10 registers the call in the car 8 so that the car 8 arrives at the departure floor at the specified time. Thereafter, as the first predicted time approaches, in step S006, the control device 10 moves the car 8 to the departure floor.

[0046] The control device 10 may register the call received from the server device 20 in step S005 in the car 8 in a state in which other calls can be given priority, or may register the call in the car 8 in step S006 instead of step S005 so that the car 8 arrives at the departure floor at the specified time. In either case, the control device 10 controls the operation of the car 8 so that the car 8 arrives at the departure floor at the specified time.

[0047] In the example of this sequence diagram, it is assumed that the user arrives at the waiting position at hall 4 after step S006. At this time, in step S007, the mobile terminal 30 detects that the reception strength of the hall radio wave exceeds the second threshold, and determines that the user has arrived at the waiting position at hall 4. The mobile terminal 30 records the actual arrival time and enters a state of waiting at hall 4.

[0048] Thereafter, in step S008, the car 8 arrives at the landing 4 on the departure floor and stops there. At this time, in step S009, the control device 10 notifies the server device 20 of the actual stopping time when the car 8 stopped at the departure floor.

[0049] Thereafter, the car door 9 and the landing door 5 open, and the passenger boards the car 8. At this time, in step S010, the mobile terminal 30 detects that the reception strength of the car radio waves from the car beacon 12 exceeds the boarding threshold. The mobile terminal 30 enters a boarding state. The mobile terminal 30 records the actual boarding time. Thereafter, in step S011, the mobile terminal 30 transmits each piece of performance information to the server device 20 in association with the device ID and the terminal ID.

[0050] Thereafter, in step S012, the server device 20 updates the first prediction model based on the performance information received in step S011.

[0051] Then, the sequence operation ends.

[0052] According to the first embodiment described above, the elevator system 1 includes a hall beacon 11, a control device 10, a mobile terminal 30, and a server device 20. The server device 20 includes a first prediction unit 23, a call control unit 22, a performance calculation unit 24, and a first update unit 25. The mobile terminal 30 transmits a call request when the reception strength of the hall radio wave exceeds a first threshold. This allows the user to call a car without operating the mobile terminal 30. After the call request is transmitted, depending on the user's behavior, such as stopping at a mailbox or moving slowly, the car 8 may arrive at the hall 4 at the departure floor before the user. While a boarding determination device such as an MBS installed on the car door 9 may detect the boarding of a user in the car 8, a car 8 not equipped with such a boarding determination device may depart for the destination floor without waiting for the user to board, triggered by the elapse of a specified stop time, the boarding of a person other than the user, or the like. In this case, a call for the car 8 is made in vain. In the elevator system 1 according to the first embodiment, the car 8 is controlled to arrive at the departure floor at the estimated first predicted time. Furthermore, the first prediction model is updated based on the waiting time that reflects the actual movement of the user. As a result, the elevator system 1 can suppress the occurrence of unnecessary calls and prevent a decrease in elevator utilization efficiency.

[0053] Furthermore, the first update unit 25 updates the first prediction model by changing the value of the first predicted time based on the waiting time. In particular, the first update unit 25 determines the difference obtained by subtracting the product of the waiting time multiplied by the first update coefficient from the first predicted time as the updated first predicted time. This allows the elevator system 1 to update the first prediction model based on a quantitative index.

[0054] When a call request associated with the terminal ID of the mobile terminal 30 and the device ID of the control device 10 is received, the first prediction unit 23 may use a first predicted time that is associated with the device ID of the control device 10 in the first prediction model and that is associated with a terminal ID different from that of the mobile terminal 30. Therefore, even when a call request is received for the first time from the mobile terminal 30, the server device 20 can use the first predicted time that was previously updated for the building 3.

[0055] When a call request associated with the terminal ID of the mobile terminal 30 and the device ID of the control device 10 is received, the first prediction unit 23 may use a first predicted time that is associated with the terminal ID of the mobile terminal 30 in the first prediction model, but is associated with a different terminal ID other than the control device 10. Therefore, even when a call request for the building 3 is received for the first time, the server device 20 can use the first predicted time that was previously updated by the mobile terminal 30.

[0056] When updating the first prediction model, the server device 20 may use the boarding time instead of the arrival time.

[0057] Embodiment 2 Fig. 5 is a functional block diagram of an elevator system according to the second embodiment. Fig. 6 is a flowchart showing an example of the operation of a mobile terminal in the elevator system according to the second embodiment. Fig. 7 is a sequence diagram showing an example of the operation performed in the elevator system according to the second embodiment. Note that parts that are the same as or equivalent to parts in the first embodiment are given the same reference numerals, and a description of these parts will be omitted.

[0058] As shown in FIG. 5, in the second embodiment, the mobile terminal 30 includes a detection unit 34, a second prediction unit 35, and a second update unit 36 ​​as functions.

[0059] The detection unit 34 includes a physical sensor and a control function for the physical sensor provided in the mobile terminal 30. For example, the detection unit 34 may be an inertial sensor, a geomagnetic sensor, a position detection sensor, etc. The detection unit 34 detects a physical quantity that indicates the user's behavior.

[0060] After the call request is transmitted by the call request unit 32, when the detection result of the detection unit 34 satisfies a specified correction condition, the second prediction unit 35 estimates a second predicted time based on the device ID. The second prediction unit 35 transmits correction information including the estimated second predicted time to the server device 20. At this time, the second prediction unit 35 estimates the second predicted time using a second prediction model. The second prediction model is a model for estimating the second predicted time, and outputs the second predicted time associated with the device ID. The second predicted time is a predicted value of the time from when the correction condition is satisfied until the user arrives at the waiting position of the hall 4. The second prediction unit 35 estimates the second predicted time by adding the second predicted time to the current time. Note that the second predicted time may be 0.

[0061] The second update unit 36 ​​calculates a corrected travel time, which is the time from the time when the correction condition is satisfied to the arrival time recorded in the recording unit 33. The second update unit 36 ​​updates the second prediction model based on the corrected travel time. Specifically, the second update unit 36 ​​updates the value of the second predicted time associated with the device ID corresponding to the hall radio signal based on the corrected travel time. For example, the second update unit 36 ​​may update the second predicted time so that the second predicted time is equal to the corrected travel time calculated immediately before. For example, the second update unit 36 ​​may update the second predicted time so that the second predicted time is equal to the product of the corrected travel time calculated immediately before and the second update coefficient.

[0062] The flowchart shown in FIG. 6 starts when the reception strength of the hall radio wave received by the mobile terminal 30 exceeds the first threshold.

[0063] In step S101, the mobile terminal 30 transmits a call request to the server device 20.

[0064] Thereafter, in step S102, the second prediction unit 35 determines whether the detection result of the detection unit 34 satisfies a correction condition. The correction condition is set in advance. As one example, the correction condition is satisfied when the inertial sensor serving as the detection unit 34 detects a physical quantity corresponding to the user's crouching movement. As another example, the correction condition is satisfied when the position sensor serving as the detection unit 34 detects a physical quantity indicating that the user has moved a specified distance or more. The correction condition may be set by the user as an arbitrary physical quantity and its threshold value, or may be selected by the user from preset values ​​prepared in advance.

[0065] If the correction condition is not satisfied in step S102, the operation of step S103 is performed. In step S103, the second prediction unit 35 determines whether the reception strength of the hall radio wave received by the receiver 31 exceeds a second threshold. If the reception strength is equal to or less than the second threshold in step S103, the operations from step S102 onwards are repeated.

[0066] If the reception strength exceeds the second threshold in step S103, the operation of step S104 is performed. In step S104, the recording unit 33 records the arrival time.

[0067] Thereafter, in step S105, the recording unit 33 determines whether or not the reception strength of the car radio waves received by the receiving unit 31 exceeds the boarding threshold. If the reception strength of the car radio waves is equal to or less than the boarding threshold in step S105, the operation of step S105 is repeated.

[0068] In step S105, if the reception strength of the car radio wave exceeds the boarding threshold, the operation of step S106 is performed. In step S106, the recording unit 33 records the boarding time. The recording unit 33 transmits the performance information to the server device 20. Thereafter, the operation of the flowchart ends.

[0069] If the correction condition is satisfied in step S102, the operation of step S107 is performed. In step S107, the second prediction unit 35 estimates the second predicted time. The second prediction unit 35 transmits the second predicted time to the server device 20.

[0070] Thereafter, in step S108, the second prediction unit 35 determines whether or not the reception strength of the hall radio waves received by the receiver 31 exceeds a second threshold. If the reception strength is equal to or less than the second threshold in step S108, the operation of step S108 is repeated.

[0071] If the reception strength exceeds the second threshold in step S108, the operation of step S109 is performed. In step S109, the recording unit 33 records the arrival time. The second updating unit 36 ​​calculates the corrected travel time.

[0072] Then, in step S110, the second update unit 36 ​​updates the second prediction model based on the corrected travel time calculated in step S109. Then, the operations from step S105 onwards are performed.

[0073] In the sequence diagram shown in Fig. 7, the operations performed from step S001 to step S012 are the same as those in the sequence diagram of Fig. 4. In the example shown in this sequence diagram, after a call request is sent, the user makes a detour and performs an operation that satisfies the correction condition, and then moves to the waiting position.

[0074] 7, after step S005, the operation of step S201 is performed. In step S201, the mobile terminal 30 detects that the correction condition is satisfied. The mobile terminal 30 estimates the second predicted time and transmits it to the server device 20.

[0075] Then, in step S202, the server device 20 receives the second predicted time from the mobile terminal 30. The server device 20 transmits a call including the second predicted time as a specified time to the control device 10. The call may include the same departure floor and destination floor as the call transmitted in step S004.

[0076] Thereafter, in step S203, the control device 10 receives a call from the server device 20. The control device 10 changes the designated time of the call registered in step S005 to the second predicted time.

[0077] Thereafter, when the second predicted time approaches, the operations from step S006 onwards are carried out.

[0078] After step S007, the mobile terminal 30 performs the operation of step S204. In step S204, the mobile terminal 30 updates the second prediction model.

[0079] According to the second embodiment described above, the mobile terminal 30 includes the detection unit 34 and the second prediction unit 35. The second prediction unit 35 estimates the second predicted time. In particular, the second prediction unit 35 estimates the second predicted time using the second predicted time associated with the device ID. When the second predicted time is estimated by the mobile terminal 30, the call control unit 22 transmits a call including the second predicted time as a designated time to the control device 10. The control device 10 controls operation so that the car 8 arrives at the departure floor at the second predicted time. This allows the elevator system 1 to make calls for the car 8 based on more specific user behavior. As a result, a decrease in elevator operation efficiency can be more reliably suppressed.

[0080] The mobile terminal 30 further includes a second update unit 36. The second update unit 36 ​​updates the second prediction model based on the corrected travel time from when the correction condition is satisfied until it is determined that the user has arrived at the waiting position. Therefore, in the elevator system 1, the second prediction model is quantitatively updated based on the actual time that indicates the behavior of the user. As a result, it is possible to more reliably suppress a decrease in elevator operation efficiency.

[0081] Next, an example of hardware constituting the server device 20 will be described with reference to FIG. FIG. 8 is a hardware configuration diagram of the server device of the elevator system according to the first or second embodiment.

[0082] Each function of the server device 20 may be realized by a processing circuit. For example, the processing circuit includes at least one processor 100a and at least one memory 100b. For example, the processing circuit includes at least one dedicated hardware 200.

[0083] When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the server device 20 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in at least one memory 100b. At least one processor 100a realizes each function of the server device 20 by reading and executing the program stored in the at least one memory 100b.

[0084] Specifically, each function of the server device 20 is realized as a processing step of the function by a program. That is, the program causes a processing circuit of the server device 20 as a computer to execute each function provided in the server device 20.

[0085] When the processing circuit includes at least one dedicated hardware 200, the processing circuit is realized, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the server device 20 is realized by a processing circuit. For example, each function of the server device 20 is realized collectively by a processing circuit.

[0086] Some of the functions of the server device 20 may be realized by dedicated hardware 200, and the other parts may be realized by software or firmware. For example, the function of the first updating unit 25 may be realized by a processing circuit as the dedicated hardware 200, and functions other than the function of the first updating unit 25 may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0087] In this way, the processing circuitry realizes each function of the server device 20 using hardware 200, software, firmware, or a combination of these.

[0088] The server device 20 may be implemented on a cloud server. In this case, the processing circuit is configured by a plurality of partial circuits. The plurality of partial processing circuits are provided in each of the plurality of devices that constitute the cloud server. The plurality of devices that constitute the cloud server may be provided in different buildings.

[0089] Although not shown, the functions of the control device 10 and the mobile terminal 30 are also realized by processing circuits equivalent to the processing circuits that realize the functions of the server device 20.

[0090] The elevator system 1 may be any type of elevator, such as an elevator system without a machine room in which the hoisting machine 6 and the control device 10 are located at the bottom or top of the elevator shaft 2, as long as it is an elevator that can be operated in response to a call from a mobile terminal 30.
