[0005] Patent Document 1: Japanese Patent Application Publication No. 2021-113125 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the elevator system described in Patent Document 1, to suppress unnecessary calls, the following setting is implemented: if the received strength of the radio wave from the floor beacon does not exceed the call threshold, no call request is sent. However, the reception sensitivity of the radio wave varies depending on the portable terminal, therefore, the set call threshold may become an inappropriate value.

[0026] The embodiments for implementing this disclosure are described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals. Repetitive descriptions of these parts are appropriately simplified or omitted.

[0027] Implementation method 1.

[0028] Figure 1 This is a schematic diagram of a building equipped with the elevator system of Embodiment 1. Figure 2 This is a diagram showing the floors of the elevator system in Implementation Method 1. Figure 3 This is a functional block diagram of the elevator system according to Implementation Method 1.

[0029] exist Figure 1 In the elevator system 1, the shaft 2 runs through all floors of the building 3. Multiple stations 4 are located on each floor of the building 3. Each station 4 is a part of the space on each floor of the building 3. Each station 4 is opposite to the shaft 2. Entrances and exits are provided between the stations 4 and the shaft 2. At each station of the multiple stations 4, a station door 5 is provided at the entrance or exit.

[0030] The traction machine 6 is located in a machine room above the hoistway 2. The main rope 7 is wound around the traction machine 6. The car 8 is suspended inside the hoistway 2 by the main rope 7. The car 8 can move up and down inside the hoistway 2 following the movement of the main rope 7 following the movement of the traction machine 6. A car door 9 is provided on the side of the car 8 opposite the landing 4. The control panel 10 is located in the machine room. The control panel 10 serves as the operation control unit, enabling overall control of actions related to the operation of the car 8 by controlling the traction machine 6.

[0031] Elevator system 1 also includes multiple floor beacons 11, car beacons 12, server device 20, and portable terminal 30.

[0032] Multiple floor beacons 11 are respectively installed at several of the multiple floor stations 4. The floor beacons 11 transmit floor radio waves containing floor-specific identifiers of the floor station 4. In addition, the floor beacons 11 can be installed at all floor stations 4, or only at specific floor stations 4 among the multiple floor stations 4.

[0033] Car beacon 12 is installed in car 8. Car beacon 12 transmits car radio waves containing a unique identifier of car 8.

[0034] Server device 20 is located in a different building than building 3. Server device 20 is able to communicate with control panel 10 via network N.

[0035] The portable terminal 30 is a device capable of displaying information and accepting information input. For example, the portable terminal 30 is a smartphone. The portable terminal 30 is held by the user of the elevator system 1. The portable terminal 30 can communicate with the server device 20 via the network N. The portable terminal 30 can receive landing radio waves and car radio waves. The portable terminal 30 stores dedicated applications that can be used in the elevator system 1. At least a portion of the functionality of the portable terminal 30 is achieved by executing the dedicated applications.

[0036] The portable terminal 30 stores pre-stored information about the combination of the departure floor and the destination floor in building 3. An automatic elevator calling mode is then set for the portable terminal 30. At the departure floor 4, as the user approaches the landing door 5, the reception strength of the landing radio waves received by the portable terminal 30 gradually increases. When the reception strength of the landing radio waves exceeds a pre-set elevator calling threshold, as per the processing specified by the automatic elevator calling mode, the portable terminal 30 sends an elevator calling request containing both the departure and destination floors to the server device 20. At this time, the user does not need to operate the portable terminal 30.

[0037] Server device 20 determines the corresponding control panel 10 based on the information contained in the elevator call request. Server device 20 sends the elevator call request to control panel 10. Control panel 10 registers the elevator call, which includes the departure floor and destination floor as shown in the call request, to car 8. After moving car 8 to the departure floor, control panel 10 moves car 8 to the destination floor. In this way, users can ride car 8 from the destination floor to the departure floor without operating the equipment.

[0038] When the workers install the landing beacon 11, car beacon 12, etc., in building 3, they perform confirmation procedures such as radio wave reception confirmation and overall operation confirmation. During the confirmation process, the workers use a standard terminal to confirm the reception of landing and car radio waves. The standard terminal is a portable terminal that receives radio waves based on a reference receiving sensitivity. For example, the transmission strength of the radio wave from the landing beacon 11 is set to the following intensity: when the standard terminal is within a specified distance of the landing door 5, the standard terminal's reception strength of the landing radio wave exceeds the call threshold.

[0039] The receiving sensitivity of the portable terminal 30 depends on its model, performance, etc., assuming various values. Furthermore, the receiving sensitivity of the portable terminal 30 can vary depending on accessories, covers, etc., of the portable terminal 30. Moreover, as... Figure 2 As shown, depending on whether the portable terminal 30 is stored in a bag, the intensity of the received radio waves, i.e., the overall receiving sensitivity, of the portable terminal 30 for the same radio wave may vary. Thus, among multiple portable terminals (not shown), their receiving sensitivity can take various values.

[0040] The portable terminal 30 allows for the individual setting of the elevator call threshold, enabling the automatic elevator call mode to be operated appropriately based on varying reception sensitivity. The server device 20 calculates an appropriate elevator call threshold based on the portable terminal 30's reception of correction waves, which are either floor or car waves. For example, the portable terminal 30 updates the new elevator call threshold with the value calculated by the server device 20. In Embodiment 1, an example of calculating the elevator call threshold based on the reception of car waves from the car beacon 12 as a correction wave is described.

[0041] like Figure 3 As shown, the portable terminal 30 includes a receiving unit 31, an elevator call request unit 32, and a result transmission unit 33. The receiving unit 31 includes an antenna capable of receiving station radio waves and car radio waves, and antenna control functions.

[0042] The elevator call request unit 32 is a function implemented by a dedicated application, and controls the action of sending elevator call requests. For example, when the automatic elevator call mode is set, the elevator call request unit 32 sends an elevator call request to the server device 20 when the reception strength of the floor radio wave received by the receiving unit 31 exceeds the elevator call threshold.

[0043] The result transmitting unit 33 collects the time-lapse of the received strength of the correction radio wave received by the receiving unit 31 according to the prescribed collection conditions. For example, as a starting collection condition, the result transmitting unit 33 begins collecting the time-lapse of the received strength when the received strength of the correction radio wave (i.e., the car radio wave) received by the receiving unit 31 exceeds a predetermined starting threshold. The result transmitting unit 33 ends the collection when the received strength of the correction radio wave meets the ending collection condition. Then, the result transmitting unit 33 generates result information indicating the time-lapse of the collected received strength of the correction radio wave and sends it to the server device 20. As an example, as a ending collection condition, the result transmitting unit 33 ends the collection when a predetermined time has elapsed since the start of the collection.

[0044] As functions, the server device 20 includes a storage unit 21, an elevator call control unit 22, an index value calculation unit 23, a candidate decision unit 24, and a threshold decision unit 25.

[0045] Storage unit 21 stores various information related to the operation of elevator system 1, such as set values ​​and data. For example, storage unit 21 stores information on the time-varying intensity of the received radio waves at the landings, measured using a standard terminal in building 3, and information on the time-varying intensity of the received radio waves in the car.

[0046] Upon receiving an elevator call request generated by the building 3, the elevator call control unit 22 uses the database stored in the storage unit 21 to determine the control panel 10 corresponding to the call request. The elevator call control unit 22 then sends the call request to the control panel 10. In this way, the elevator call control unit 22 controls the portable terminal 30 to process the elevator call registration on the control panel 10.

[0047] The index value calculation unit 23 calculates the index value based on the time shift of the received intensity of the correction radio wave contained in the result information received from the portable terminal 30. Specifically, the index value calculation unit 23 calculates the index value based on the received intensity value within the adoption interval from a specific time to a specific time in the time shift. The index value calculation unit 23 calculates any square of the maximum value, minimum value, and average value of the received intensity within the adoption interval as the index value.

[0048] The candidate decision unit 24 determines the candidate threshold using a standard index value and an index value calculated by the index value calculation unit 23. The standard index value is calculated based on the corrected radio waves received by the standard terminal, and is calculated using the same calculation method as the index value, based on the time-varying intensity of the received radio waves at the floor level measured using the standard terminal in building 3. The standard index value can be stored in the storage unit 21, or it can be calculated by the index value calculation unit 23 based on the information stored in the storage unit 21. The candidate threshold is a value that becomes a candidate for the updated call threshold.

[0049] The candidate decision unit 24 calculates the candidate threshold by selecting a smaller value for the index value relative to the standard index value. This calculation can be performed using any method. For example, the candidate decision unit 24 can use the correction value obtained by multiplying the difference between the index value and the standard index value by a predetermined coefficient, and then adding this correction value to the benchmark call threshold as the candidate threshold. Alternatively, the candidate decision unit 24 can use the correction value obtained by multiplying the quotient obtained by dividing the index value by the standard threshold by a predetermined coefficient, and then multiplying this correction value to the benchmark call threshold as the candidate threshold. Furthermore, the candidate decision unit 24 can select the category value corresponding to the magnitude of the index value relative to the standard index value from multiple category values ​​as the candidate threshold. In this case, specifically, three category values—high, medium, and low—are prepared in advance as candidate thresholds. If the difference between the index value and the standard index value falls within the range corresponding to the "high" category value, then the "high" category value is selected as the candidate threshold.

[0050] The threshold determination unit 25 determines the candidate threshold determined by the candidate determination unit 24 as the updated call threshold to be used in the portable terminal 30. Alternatively, the threshold determination unit 25 may select the value closest to the candidate threshold from multiple classification values ​​as the updated call threshold. The threshold determination unit 25 sends the determined call threshold and the instruction to update the call threshold to the portable terminal 30.

[0051] Next, use Figure 4 An example of calculating the index value is provided.

[0052] Figure 4 It is a graph showing the time-varying intensity of the received corrected radio wave obtained in the elevator system of Embodiment 1.

[0053] exist Figure 4 In the graph, the vertical axis represents the received radio wave intensity [dBm (decibels milliwatts)]. The horizontal axis represents time. The starting point of time is the point in time when the initial collection conditions are met. The solid line curve A represents the received intensity of the correction radio wave received by the portable terminal 30. The dashed line curve B represents the received intensity of the correction radio wave received by the standard terminal. The correction radio wave is the car radio wave from the car beacon 12.

[0054] As shown in graph A over time, the received radio wave strength of the car varies depending on the distance between the car 8 and the portable terminal 30. During the interval t0~t1, although the user has reached floor 4 of the departure level, the car 8 stops at the floor away from the departure level. Then, during the interval t1~t2, the car 8 moves towards the departure level and stops. After time t2, the user rides the car 8 and moves through it.

[0055] The reception strength when the portable terminal 30 and the car 8 are in the same position is preferred is used as the index value and the standard index value, respectively. Specifically, when the car radio wave is used as the correction radio wave, the reception strength when the user is riding in the car 8 is preferably used as the index value. In the index value calculation unit 23, the slope of the reception strength over time is used as a value reflecting the positional relationship between the user and the car 8, thereby determining the range in which the index value should be calculated.

[0056] The index value calculation unit 23 calculates the change in received signal strength between a given moment and a predetermined judgment time, using this change as the slope of the received signal strength. That is, at each moment, it calculates a moving average of the change in received signal strength related to the judgment time. The index value calculation unit 23 uses the point in time where the change in received signal strength within the judgment time exceeds a first judgment value but falls below a second judgment value as the starting point of the adoption interval. Figure 4 In the example, during the interval from time t1 to t2, the car 8 moves close to the portable terminal 30, causing a sharp increase in reception strength, exceeding the first judgment value. Then, after time t2, the car 8 stops, and the positional relationship between the car 8 and the portable terminal 30 no longer changes significantly, thus the change in reception strength within the judgment time falls below the second judgment value. In this case, the interval for calculating the index value is determined to begin.

[0057] In addition, in order to reduce the impact of the deviation in received strength on the determination, the index value calculation unit 23 may also take the time point when the change in received strength within the determination time exceeds the first determination value after the state exceeds the first time, and the change in received strength within the determination time becomes the state below the second determination value after the state exceeds the second time as the starting point of the adoption interval.

[0058] Furthermore, to reduce the impact of received strength deviation on the determination, the index value calculation unit 23 can also perform a determination related to the first determination value after the state where the change in received strength within the determination time is below the pre-determined value has exceeded the pre-determined time. In this case, the index value calculation unit 23 can also use the time point where the change in received strength within the determination time exceeds the pre-determined value after the pre-determined time has exceeded the first determination value and then becomes below the second determination value as the starting point of the adoption interval. Figure 4 In this context, the interval between time t0 and t1 corresponds to a state where the change in received intensity is below the pre-determined value.

[0059] The adopted interval can be a specified time period starting from the starting point, or it can be the last moment included in the result information. The index value calculation unit 23 calculates the index value based on the received intensity value within the adopted interval.

[0060] As shown in graph B, the standard index value can also be calculated based on the value of the adoption range set with the same benchmark as the index value.

[0061] exist Figure 4 In this example, the indicator value is smaller than the standard indicator value. In this case, the candidate threshold is calculated to be a value smaller than the call threshold used as a benchmark.

[0062] Next, use Figure 5 An example illustrating the operation of elevator system 1.

[0063] Figure 5 This is a flowchart illustrating a portion of the operation of the elevator system in Implementation Method 1.

[0064] Figure 5 The flowchart begins when the portable terminal 30 generates result information after collecting data on the received strength of the corrected radio waves over time. For example, the portable terminal 30 may also generate result information whenever an elevator call request is sent. Furthermore, the portable terminal 30 may collect the received strength to generate result information when an elevator call request is sent after a predetermined period, such as one month, since the last collection. Additionally, the portable terminal 30 may collect the received strength to generate result information whenever an elevator call request is sent with the collection setting enabled.

[0065] In step S01, the portable terminal 30 sends the result information to the server device 20.

[0066] Then, in step S02, the index value calculation unit 23 of the server device 20 calculates the index value based on the received result information.

[0067] Then, in step S03, the candidate decision unit 24 calculates the candidate threshold based on the standard index value and the index value calculated in step S02.

[0068] Then, in step S04, the threshold determination unit 25 determines the call threshold to be updated. The threshold determination unit 25 sends the determined value to the portable terminal 30.

[0069] Then, in step S05, the portable terminal 30 updates the elevator call threshold to the value determined in step S04. The flowchart then concludes.

[0070] According to Embodiment 1 described above, the elevator system 1 includes a control panel 10 as an operation control unit, an index value calculation unit 23, and a candidate decision unit 24. When the received signal strength at a landing exceeds a call threshold, the portable terminal 30 sends a call request. The operation control unit registers the call based on the call request sent from the portable terminal 30 to the car 8. The candidate decision unit 24 uses a standard index value and an index value to determine the candidate threshold. In particular, the index value calculation unit 23 calculates the index value using any square of the maximum, minimum, and average received signal strength within a range. Therefore, the elevator system 1 can calculate a candidate threshold as an appropriate call threshold. If the call threshold is too high or too low, the user may have to wait for the car 8 to arrive, or the car 8 may arrive too early and the user may not be able to board. According to Embodiment 1, an appropriate call threshold is calculated, thus improving user convenience.

[0071] Furthermore, the standard indicator values ​​are calculated based on the reception strength of the standard terminal over time. The standard terminal is selected based on specified specifications. Therefore, even if the building and elevator car differ, the indicator values ​​can be standardized. As a result, the accuracy of various settings when managing elevator call thresholds can be improved.

[0072] Furthermore, the index value calculation unit 23 determines the starting point of the adopted interval based on the first determination quantity, the second determination quantity, etc. Therefore, in Embodiment 1, it is possible to estimate with high accuracy the time period during which the user enters the elevator car 8 in the time progression contained in the result information. As a result, it is possible to improve the accuracy of the index value when the calculation is performed under the same conditions as the calculation of the standard index value.

[0073] Furthermore, when determining the starting point of the interval, the index value calculation unit 23 can also use pre-determined quantities and pre-time. Therefore, the accuracy of the calculated index value can be further improved.

[0074] Furthermore, the candidate decision unit 24 calculates the candidate threshold by making the smaller the index value relative to the standard index value. The smaller the index value relative to the standard index value, the lower the receiving sensitivity of the portable terminal 30 is compared to the receiving sensitivity of the standard terminal. Therefore, it is possible to calculate the candidate threshold as an appropriate call threshold more reliably.

[0075] Furthermore, elevator system 1 also includes a threshold determination unit 25. The threshold determination unit 25 determines the candidate threshold as the updated call threshold. For example, when delegating the setting of the call threshold to the user, setting the lowest selectable call threshold could lead to frequent useless calls and potentially reduce elevator operating efficiency. In elevator system 1, by automatically updating the appropriate call threshold, such extreme settings can be suppressed. As a result, the reduction in the operating efficiency of elevator system 1 can be prevented, improving the overall user convenience of elevator system 1.

[0076] Furthermore, elevator system 1 can be any type of elevator that can be operated by calling from portable terminal 30, such as an elevator system without a machine room where the traction machine 6 and control panel 10 are located at the bottom or top of the shaft 2.

[0077] In addition, the conditions for the end of the collection of results sent by the 33 can also be conditions such as when the car 8 arrives at the destination floor or when the user gets off the stairs at the destination floor.

[0078] Next, use Figures 6-8 The first variation of Implementation Method 1 is described below.

[0079] Figure 6 This is a functional block diagram of the first variation of the elevator system in Implementation 1. Figure 7 This is an example of the screen displayed on the portable terminal of the first modification of the elevator system according to Embodiment 1. Figure 8 This is a flowchart illustrating the operation of a first variation of the elevator system according to Embodiment 1.

[0080] like Figure 6 As shown, in the first modification, the server device 20 also includes a prompting unit 26 as a function. Furthermore, although not shown, the prompting unit 26 can also be provided as a function of the portable terminal 30, or a portion of the functions of the prompting unit 26 can be provided in the server device 20, while other portions can be provided in the portable terminal 30.

[0081] The prompting unit 26 generates a first candidate value range that includes the candidate threshold determined by the candidate decision unit 24. The prompting unit 26 prompts the first candidate value range in a manner that allows selection of a value from the first candidate value range, i.e., it displays the first candidate value range on the screen of the portable terminal 30.

[0082] The first candidate value range is a range that includes the candidate threshold, and it can be any range that can be set as the call threshold. For example, the prompting unit 26 can also generate a first candidate range with the candidate threshold as the lower limit value. The prompting unit 26 can also generate a first candidate range with the candidate threshold as the middle value. In addition, the first candidate value range may not be a specific numerical value, but may be displayed as a classification such as "high", "medium", or "low".

[0083] After the prompting unit 26 displays the first candidate value range, the threshold determination unit 25 determines the value selected by the user via the portable terminal 30 as the updated call threshold.

[0084] Figure 7The portable terminal 30 displays a screen showing values ​​from 5 to 9 as the first candidate value range. At this time, the candidate threshold is 7. The first candidate value range is determined by subtracting or adding a predetermined likelihood value of 2 from 7 as the lower or upper limit. The portable terminal 30 accepts a value of 8. In this case, the threshold determination unit determines 8 as the updated call threshold.

[0085] exist Figure 8 In the flowchart shown, steps S01 to S03 are... Figure 5 The steps in the flowchart shown are the same. In the first variation, the action of step S11 is performed after step S03.

[0086] In step S11, the prompting unit 26 generates a first candidate value range. The prompting unit 26 then prompts the portable terminal 30 with the first candidate value range. Alternatively, the portable terminal 30 may not display the first candidate value range when the dedicated application screen is not open, but may display the first candidate value range when the dedicated application screen is open.

[0087] Then, in step S12, the threshold determination unit 25 determines whether the selection of a value from the first candidate value range has been accepted by the portable terminal 30.

[0088] If no value is selected in step S12, step S12 is repeated. If a value is selected in step S12, actions from step S04 onwards are performed. The steps of S04 and S05 are... Figure 5 The steps in the flowchart shown are the same. That is, determine and update the elevator call threshold. Then, the flowchart's actions end.

[0089] According to the first variation of Embodiment 1 described above, the elevator system 1 further includes a prompting unit 26. The prompting unit 26 displays a first candidate value range, including candidate thresholds, on the portable terminal 30. The threshold determination unit 25 determines the value selected from the first candidate value range as the updated call threshold. For example, depending on their walking speed and personality, users sometimes wish to set the call threshold to be larger or smaller than the currently set value. Specifically, users with slow walking speeds can increase the call threshold to delay the timing of call registration in the car 8, allowing them to ride the car 8 without feeling uneasy about the car door potentially closing. In this case, the first candidate value range is set to include candidate thresholds, thus becoming a range of appropriate values. In this way, users can determine the appropriate call threshold based on various situations.

[0090] Next, a second variation of embodiment 1 will be described.

[0091] Figure 9 This is an example of the screen displayed on the portable terminal of the second modification of the elevator system in Embodiment 1. Furthermore, in Figure 9 The functions of server device 20 are not shown in the figure.

[0092] In the second variation, the prompting unit 26 generates a second candidate value range instead of a first candidate value range. The second candidate value range is a range of values ​​that can be set as the call threshold. Furthermore, the prompting unit 26 uses the candidate threshold determined by the candidate decision unit 24 as the recommended value.

[0093] like Figure 9 As shown, the prompting unit 26 displays the candidate threshold as a recommended value along with the range of selectable second candidate values ​​on the screen of the portable terminal 30. In this example, the range of second candidate values ​​is 1 to 10, and the candidate threshold is 7.

[0094] After the prompting unit 26 displays the range of the second candidate values, the threshold determination unit 25 determines the value selected by the user via the portable terminal 30 as the updated call threshold.

[0095] According to the second variation of Embodiment 1 described above, the prompting unit 26 displays the candidate threshold and the second candidate value range together on the portable terminal 30. For example, if only the second candidate value range is prompted to the user for selection, the user cannot know the appropriate threshold for their own portable terminal 30, and therefore may be confused about the setting. In addition, it is possible to set an extreme setting such as setting the minimum value that the user can set as the elevator call threshold. In the elevator system 1 of this variation, the user can set the desired value as the elevator call threshold while considering an appropriate value.

[0096] Implementation method 2.

[0097] Figure 10 This is a schematic diagram of a building equipped with the elevator system of Embodiment 2. Furthermore, parts that are identical or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0098] In the elevator system 1 of Embodiment 2, floor waves are used as correction waves instead of car waves. Although not shown, the result transmission unit 33 of the portable terminal 30 generates a time shift of the reception strength of the floor waves received by the receiving unit 31 as result information when the portable terminal 30 is present at the floor 4. For example, the result transmission unit 33 may also generate result information by using the reception of the floor waves as the starting condition for collection.

[0099] The standard index value is calculated based on the received strength of the station radio waves when the portable terminal 30 is present at station 4.

[0100] Although not illustrated, the index value calculation unit 23 can also calculate the index value based on the same benchmark as in Embodiment 1, according to the result information. In this case, the index value calculation unit 23 can also use values ​​that have been appropriately modified compared to Embodiment 1, such as the first determination value, the second determination value, the first time, the second time, the pre-determination amount, and the pre-determination time, depending on the condition of each station 4.

[0101] According to Embodiment 2 described above, the landing signal from the landing beacon 11 is used as a correction signal. In this case, similar to Embodiment 1, the elevator system 1 can calculate a candidate threshold as an appropriate call threshold.

[0102] Furthermore, although not illustrated, the landing wave included in the result information could also be the landing wave received by the receiving unit 31 when the portable terminal 30 is inside the car 8 and the car 8 is moving. In this case, the correction wave is the landing wave from the landing beacons 11 installed on each floor, i.e., multiple landing beacons on each floor. The portable terminal 30 repeatedly approaches and moves away from the multiple landing beacons on each floor. The result information includes the time progression of the received strength of the correction wave, which periodically increases and decreases to some extent. In this case, the index value calculation unit 23 can also calculate the maximum value of the received strength of the correction wave as the index value. In addition, the index value calculation unit 23 can also calculate the average of the multiple maximum values ​​of the received strength of the correction wave as the index value. The standard index value can also be determined based on the same value received by the standard terminal, using the same reference as the index value. Therefore, it is possible to calculate the candidate threshold for the elevator call threshold based on the same conditions during the movement of the car 8.

[0103] Next, use Figure 11 Examples illustrating the hardware that constitutes server device 20.

[0104] Figure 11 This is a hardware structure diagram of the server device for the elevator system in implementation method 1 or 2.

[0105] The functions of the server device 20 can be implemented by processing circuitry. For example, the processing circuitry includes at least one processor 100a and at least one memory 100b. For example, the processing circuitry includes at least one dedicated hardware 200.

[0106] When the processing circuitry includes at least one processor 100a and at least one memory 100b, the functions of the server device 20 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is described as a program. At least one of the software and firmware is stored in at least one memory 100b. The at least one processor 100a implements the functions of the server device 20 by reading and executing the program stored in the at least one memory 100b.

[0107] Specifically, the functions of the server device 20 are implemented by a program as processing steps for each function. That is, the program causes the processing circuitry of the server device 20, which is a computer, to execute the functions possessed by the server device 20.

[0108] When the processing circuitry has at least one dedicated hardware unit 200, the processing circuitry may be implemented by, for example, a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the server device 20 may be implemented by a separate processing circuitry. Alternatively, each function of the server device 20 may be implemented uniformly by a processing circuitry.

[0109] Regarding the various functions of the server device 20, some can be implemented using dedicated hardware 200, while others can be implemented using software or firmware. For example, the functions of the elevator call control unit 22 can be implemented by a processing circuit that is a dedicated hardware 200, and functions other than those of the elevator call control unit 22 can be implemented by at least one processor 100a reading and executing programs stored in at least one memory 100b.

[0110] In this way, the processing circuitry implements the functions of the server device 20 through hardware 200, software, firmware, or a combination thereof.

[0111] Furthermore, server device 20 can also be implemented on a cloud server. In this case, the processing circuitry consists of multiple circuit components. These multiple processing circuit components are respectively located in multiple devices constituting the cloud server. The multiple devices constituting the cloud server can also be located in different buildings.

[0112] Although not shown, the functions of the control panel 10 and the portable terminal 30 are implemented by the same processing circuitry that implements the functions of the server device 20.

[0113] In addition, at least one of the functions of the storage unit 21, the index value calculation unit 23, the candidate decision unit 24, and the threshold decision unit 25 may be provided in the portable terminal 30 or the control panel 10 instead of the server device 20.
