[0001] The present disclosure relates to elevator systems and programs. [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] In elevator systems such as that described in Patent Document 1, in order to reduce unnecessary calls, settings are made so that call requests are not transmitted unless the reception strength of radio waves from hall beacons exceeds a call threshold. However, because radio wave reception sensitivity varies depending on the mobile terminal, there is a risk that the set call threshold may be an inappropriate value.

[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 and a program capable of calculating an appropriate call threshold value. [Means for solving the problem]

[0006] The elevator system according to the present disclosure includes an operation control unit that registers, in a car, a call based on a call request transmitted from a mobile terminal when the reception strength of hall radio waves received by the mobile terminal from a hall beacon installed at the hall exceeds a call threshold; an index value calculation unit that calculates an index value for corrected radio waves, which are car radio waves from a car beacon installed in the car, from the time progression of the reception strength when the corrected radio waves are received by the mobile terminal; and a candidate determination unit that determines a candidate threshold that is a candidate for the updated call threshold using the standard index value and the index value.

[0007] The elevator system according to the present disclosure includes an operation control unit that registers, in a car, a call based on a call request transmitted from a mobile terminal when the reception strength of a hall radio wave received by the mobile terminal from a hall beacon installed at the hall exceeds a call threshold; an index value calculation unit that calculates an index value for a corrected hall radio wave from the change over time in reception strength when the corrected radio wave is received by the mobile terminal; and a candidate determination unit that determines a candidate threshold that is a candidate for the updated call threshold using the standard index value and the index value.

[0008] The program according to the present disclosure causes a computer provided in an elevator system that registers calls in a car based on call requests transmitted from a mobile terminal when the reception strength of hall radio waves received by the mobile terminal from a hall beacon provided at the hall exceeds a call threshold to execute an index value calculation step that calculates an index value from the time progression of the reception strength when either the hall radio waves or the car radio waves are received by the mobile terminal, and a candidate determination step that determines a candidate threshold that is a candidate for the updated call threshold using the standard index value and the index value. [Effects of the Invention]

[0011] 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.

[0012] Embodiment 1 Fig. 1 is a schematic diagram of a building in which an elevator system according to embodiment 1 is installed. Fig. 2 is a diagram showing a hall of the elevator system according to embodiment 1. Fig. 3 is a functional block diagram of the elevator system according to embodiment 1.

[0013] In the elevator system 1 of Figure 1, 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.

[0014] The hoisting machine 6 is provided in a machine room located above the hoistway 2. A main rope 7 is wound around the hoistway 6. A 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. A control panel 10 is provided in the machine room. As an operation control unit, the control panel 10 can control the overall operation of the car 8 by controlling the hoisting machine 6.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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 panel 10 via the network N.

[0019] 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.

[0020] Information on the combination of a departure floor and a destination floor in building 3 is stored in advance in mobile terminal 30. In the following, it is assumed that automatic call mode is set in mobile terminal 30. When a user approaches hall door 5 at hall 4 of the departure floor, 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 call threshold, mobile terminal 30 transmits a call request including the departure floor and the destination floor to server device 20 as processing specified in the automatic call mode. At this time, the user does not operate mobile terminal 30.

[0021] The server device 20 identifies the corresponding control panel 10 from the information included in the call request. The server device 20 transmits the call request to the control panel 10. The control panel 10 registers a call including the departure floor and destination floor indicated in the call request in the car 8. The control panel 10 moves the car 8 to the departure floor, and then to the destination floor. In this way, the user can board the car 8 and move from the destination floor to the departure floor without operating any equipment.

[0022] When workers install the hall beacon 11, car beacon 12, etc. in the building 3, the workers perform confirmation work such as confirming reception of radio waves and checking overall operation. In the confirmation work, the workers use a standard terminal to confirm reception of hall radio waves and car radio waves. The standard terminal is a portable terminal that receives radio waves with a standard reception sensitivity. For example, the transmission strength of the radio waves from the hall beacon 11 is set to a strength such that when the standard terminal is located within a specified distance from the hall door 5, the reception strength of the hall radio waves by the standard terminal exceeds the call threshold.

[0023] The radio wave reception sensitivity of the mobile terminal 30 depends on the model, performance, etc., and is expected to take on various values. The reception sensitivity of the mobile terminal 30 may also change depending on accessories, covers, etc., attached to the mobile terminal 30. Furthermore, as shown in FIG. 2, the overall reception sensitivity, which is the strength with which the mobile terminal 30 receives radio waves for the same radio wave, may change depending on whether the mobile terminal 30 is stored in a bag. In this way, the radio wave reception sensitivity of multiple mobile terminals (not shown) may take on various values.

[0024] Since the call threshold can be set individually in the mobile terminal 30, the automatic call mode can be operated appropriately according to individual situations with different reception sensitivities. The server device 20 can calculate an appropriate call threshold based on the reception results of corrected radio waves, which are hall radio waves or car radio waves, by the mobile terminal 30. For example, the mobile terminal 30 updates and uses the value calculated by the server device 20 as a new call threshold. In the first embodiment, an example will be described in which the call threshold is calculated based on the reception results of car radio waves from the car beacon 12 as corrected radio waves.

[0025] 3, the mobile terminal 30 includes, as its functions, a receiver 31, a call request unit 32, and a result transmitter 33. The receiver 31 includes an antenna capable of receiving hall radio waves and car radio waves, and a function for controlling the antenna.

[0026] 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 wave received by the receiver 31 exceeds a call threshold, the call request unit 32 sends a call request to the server device 20.

[0027] The result transmitting unit 33 collects the time transition of the reception strength of the corrected radio waves received by the receiving unit 31 based on specified collection conditions. As an example, the result transmitting unit 33 starts collecting the time transition of the reception strength when the reception strength of the car radio waves of the corrected radio waves received by the receiving unit 31 exceeds a specified start threshold, as a start collection condition. The result transmitting unit 33 ends the collection when the reception strength of the corrected radio waves meets the end collection condition. Thereafter, the result transmitting unit 33 creates result information indicating the time transition of the reception strength of the collected corrected radio waves and transmits it to the server device 20. As an example, the result transmitting unit 33 ends the collection when a specified time has elapsed since the start of collection, as a end collection condition.

[0028] The server device 20 includes a storage unit 21, a call control unit 22, an index value calculation unit 23, a candidate determination unit 24, and a threshold determination unit 25 as functions.

[0029] The storage unit 21 stores various information such as setting values ​​and data related to the operation of the elevator system 1. For example, the storage unit 21 stores information on the time transition of the reception strength of hall radio waves measured using a standard terminal in the building 3, information on the time transition of the reception strength of car radio waves, etc.

[0030] When the call control unit 22 receives a call request made in the building 3, it uses the database stored in the storage unit 21 to identify the control panel 10 corresponding to the call request. The call control unit 22 transmits the call request to the control panel 10. In this way, the call control unit 22 controls the process of registering a call to the control panel 10 by the mobile terminal 30.

[0031] The index value calculation unit 23 calculates an index value based on the time transition of the reception strength of the corrected radio wave included in the result information received from the mobile terminal 30. Specifically, the index value calculation unit 23 calculates the index value from the value of the reception strength in an adopted interval from a specific time to a specific time within the time transition. The index value calculation unit 23 calculates one of the maximum, minimum, or average value of the reception strength in the adopted interval and sets it as the index value.

[0032] The candidate determination unit 24 determines a candidate threshold value using the standard index value and the index value calculated by the index value calculation unit 23. The standard index value is an index value calculated based on the corrected radio waves received by the standard terminal, and is a value calculated from the time transition of the reception strength of the hall radio waves measured using the standard terminal in the building 3 by the same calculation method as the index value. The standard index value may be stored in the storage unit 21, or may be calculated by the index value calculation unit 23 based on information stored in the storage unit 21. The candidate threshold value is a value that is a candidate for the call threshold value after the update.

[0033] The candidate designator 24 calculates the candidate threshold value so that the smaller the index value is relative to the standard index value, the smaller the value. Any method may be used for this calculation. For example, the candidate designator 24 may determine the candidate threshold value by adding a correction value obtained by multiplying the difference between the index value and the standard index value by a specified coefficient to the reference call threshold. For example, the candidate designator 24 may determine the candidate threshold value by multiplying the quotient of the index value divided by the standard threshold by a specified coefficient to the correction value obtained by multiplying the quotient by the standard threshold. Alternatively, the candidate designator 24 may determine the candidate threshold value by a classification value corresponding to the magnitude of the index value relative to the standard index value from among multiple classification values. In this case, specifically, three classification values, high, medium, and low, are prepared as candidate threshold values, and when the difference between the index value and the standard index value is in the range corresponding to the classification value of "high," the classification value of "high" is determined as the candidate threshold.

[0034] The threshold determination unit 25 determines the candidate threshold determined by the candidate determination unit 24 as the updated call threshold to be used by the mobile terminal 30. The threshold determination unit 25 may determine the value closest to the candidate threshold from among multiple classification values ​​as the updated call threshold. The threshold determination unit 25 transmits the determined call threshold and a command to update the call threshold to the mobile terminal 30.

[0035] Next, an example of how the index value is calculated will be described with reference to FIG. FIG. 4 is a graph showing a time transition of the reception strength of the corrected radio wave acquired in the elevator system in the first embodiment.

[0036] In Figure 4, the vertical axis represents the received radio wave strength [dBm (decibels in milliwatts)]. The horizontal axis represents time. The starting point of time is the point at which the start collection condition is met. The solid line graph A represents the received radio wave strength of the corrected radio wave received by the mobile terminal 30. The dashed line graph B represents the received radio wave strength of the corrected radio wave received by the standard terminal. The corrected radio wave is a car radio wave from the car beacon 12.

[0037] As shown by the time progression of graph A, the reception strength of the car radio waves changes depending on the distance between car 8 and mobile terminal 30. In the section from time t0 to t1, the passenger arrived at hall 4 at the departure floor, but car 8 was parked at a floor away from the departure floor. Then, between time t1 and t2, car 8 moved to the departure floor and stopped there. Then, from time t2 onwards, the passenger boarded car 8 and traveled by car 8.

[0038] It is desirable to adopt the reception strength when the mobile terminal 30 and the car 8 are in a similar positional relationship as the index value and the standard index value, respectively. Specifically, when the car radio wave is adopted as the correction radio wave, it is desirable to adopt the reception strength when the user is in the car 8 as the index value. The index value calculation unit 23 determines the adopted section for calculating the index value by using the gradient of the time change in the reception strength as a value reflecting the positional relationship between the user and the car 8.

[0039] The index value calculation unit 23 calculates, as the gradient of the reception strength, the amount of change in reception strength at each time between a certain time and a time preceding that time by a specified judgment time. That is, at each time, a moving average value of the amount of change in reception strength over the judgment time is calculated. The index value calculation unit 23 determines the start point of the adopted section when the amount of change in reception strength over the judgment time exceeds a first judgment value and then falls below a second judgment value. In the example of FIG. 4 , in the section between times t1 and t2, the car 8 moves closer to the mobile terminal 30, so the reception strength increases rapidly and the amount of change exceeds the first judgment value. After that, after time t2, the car 8 stops and the positional relationship between the car 8 and the mobile terminal 30 no longer changes significantly, so the amount of change in reception strength over the judgment time falls below the second judgment value. In this case, it is determined that the adopted section for which the index value should be calculated has started.

[0040] In addition, in order to reduce the influence of variations in reception strength on the judgment, the index value calculation unit 23 may determine that the starting point of the adopted period is the point in time when the amount of change in reception strength during the judgment time exceeds the first judgment value after the first time has elapsed, and when the amount of change in reception strength during the judgment time becomes equal to or less than the second judgment value after the second time has elapsed.

[0041] Furthermore, in order to reduce the influence of variations in reception strength on the determination, the index value calculation unit 23 may perform a determination regarding the first determination value after the state in which the amount of change in reception strength during the determination time is equal to or less than the predetermined amount has elapsed since the predetermined time. In this case, the index value calculation unit 23 may determine that the start point of the adopted period is the time when the amount of change in reception strength during the determination time is equal to or less than the predetermined amount, exceeds the first determination amount, and then becomes equal to or less than the second determination amount after the period in which the amount of change in reception strength is equal to or less than the predetermined amount has elapsed since the predetermined time. In FIG. 4, the period from time t0 to t1 corresponds to the state in which the amount of change in reception strength is equal to or less than the predetermined amount.

[0042] The adopted interval may be a period of time that continues for a specified time from the start point, or may be the last time included in the result information. The index value calculation unit 23 calculates an index value from the value of the reception strength in the adopted interval.

[0043] As shown in graph B, the standard index value may be calculated from the value of the adopted section set according to the same criteria as the index value.

[0044] 4, the index value is smaller than the standard index value. In this case, the potential threshold is calculated to be a value smaller than the reference call threshold.

[0045] Next, an example of the operation of the elevator system 1 will be described with reference to FIG. FIG. 5 is a flowchart showing a part of the operation of the elevator system according to the first embodiment.

[0046] The flowchart in Fig. 5 starts when the mobile terminal 30 completes collection of the time transition of the reception strength of the corrected radio wave and generates result information. For example, the mobile terminal 30 may generate result information each time it performs an operation to send a call request. Note that the mobile terminal 30 may collect the reception strength and generate result information when it performs an operation to send a call request after a specified period, such as one month, has elapsed since the previous collection. Also, the mobile terminal 30 may collect the reception strength and generate result information each time it performs an operation to send a call request while the setting for whether or not to collect is on.

[0047] In step S01, the mobile terminal 30 transmits result information to the server device 20.

[0048] Then, in step S02, the index value calculation unit 23 of the server device 20 calculates an index value based on the received result information.

[0049] Thereafter, in step S03, the candidate designator 24 calculates a candidate threshold value based on the standard index value and the index value calculated in step S02.

[0050] Then, in step S04, the threshold value determination unit 25 determines a call threshold value to be updated. The threshold value determination unit 25 transmits the determined value to the mobile terminal 30.

[0051] Then, in step S05, the mobile terminal 30 updates the call threshold to the value determined in step S04, and then the operation of the flowchart ends.

[0052] According to the first embodiment described above, the elevator system 1 includes the control panel 10, which is an operation control unit, the index value calculation unit 23, and the candidate determination unit 24. The mobile terminal 30 transmits a call request when the reception strength of the hall radio wave exceeds the call threshold. The operation control unit registers a call based on the call request transmitted from the mobile terminal 30 in the car 8. The candidate determination unit 24 determines the candidate threshold using the standard index value and the index value. In particular, the index value calculation unit 23 calculates the maximum, minimum, or average of the reception strength in the adopted section as the index value. This allows the elevator system 1 to calculate the candidate threshold, which is an appropriate call threshold. If the call threshold is too large or too small, users may have to wait for the car 8 to arrive, or the car 8 may arrive too early and be unable to board. According to the first embodiment, an appropriate call threshold is calculated, thereby improving user convenience.

[0053] The standard index value is calculated from the time transition of the reception strength of the standard terminal. The standard terminal is a terminal selected based on the prescribed specifications. Therefore, even if the building and car are different, the index value can be unified. As a result, the accuracy of each setting value when managing the call threshold can be improved.

[0054] Furthermore, the index value calculation unit 23 determines the start point of the adopted section based on the first judgment amount, the second judgment amount, etc. Therefore, in the first embodiment, it is possible to accurately estimate the time period during which the user is riding in the car 8 from the time transition included in the result information. As a result, it is possible to improve the accuracy of calculating the index value in the same situation as the situation in which the standard index value was calculated.

[0055] Furthermore, the index value calculation unit 23 may further use a pre-determined amount and a pre-time when determining the start point of the adopted section, thereby further improving the accuracy of calculating the index value.

[0056] Furthermore, the candidate designator 24 calculates the candidate threshold so that the smaller the index value is relative to the standard index value, the smaller the value becomes. The smaller the index value is relative to the standard index value, the lower the receiving sensitivity of the mobile terminal 30 is compared to the receiving sensitivity of the standard terminal. This makes it possible to more reliably calculate the candidate threshold, which is an appropriate call threshold.

[0057] The elevator system 1 also includes a threshold value determination unit 25. The threshold value determination unit 25 determines the candidate threshold value as the updated call threshold value. For example, if the user is left to set the call threshold value, the lowest selectable call threshold value may be set, which may result in frequent unnecessary calls and reduced elevator operation efficiency. By automatically updating the appropriate call threshold value in the elevator system 1, such extreme settings can be prevented. As a result, a decrease in the operation efficiency of the elevator system 1 can be prevented, and the convenience of users of the entire elevator system 1 can be improved.

[0058] 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 control panel 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.

[0059] The collection condition for ending the result transmission unit 33 may be a condition such as when the car 8 arrives at the destination floor, when the passenger gets off at the destination floor, or the like.

[0060] Next, a first modification of the first embodiment will be described with reference to FIGS. Fig. 6 is a functional block diagram of a first modified example of the elevator system according to embodiment 1. Fig. 7 is an example of a screen displayed on a mobile terminal of the first modified example of the elevator system according to embodiment 1. Fig. 8 is a flowchart showing the operation of the first modified example of the elevator system according to embodiment 1.

[0061] 6, in the first modified example, the server device 20 further includes a function of a presenting unit 26. Although not shown, the presenting unit 26 may be provided as a function of the mobile terminal 30, or some of the functions of the presenting unit 26 may be provided in the server device 20 and the other units may be provided in the mobile terminal 30.

[0062] The presentation unit 26 generates a first candidate value range that includes the candidate threshold determined by the candidate determination unit 24. The presentation unit 26 presents the first candidate value range, i.e., displays it on the screen of the mobile terminal 30, so that a value can be selected from within the first candidate value range.

[0063] The first candidate value range may be a range that includes the candidate threshold and that can be set as a call threshold. For example, the presentation unit 26 may generate a first candidate range in which the candidate threshold is the lower limit value. The presentation unit 26 may generate a first candidate range in which the candidate threshold is the middle value. Note that the first candidate value range may be displayed as a category such as "high," "medium," or "low" instead of a specific numerical value.

[0064] After the first candidate value range is displayed by the presentation unit 26, the threshold determination unit 25 determines the value selected by the user via the mobile terminal 30 as the call threshold to be updated.

[0065] FIG. 7 shows the screen of the mobile terminal 30, displaying values ​​from 5 to 9 as the first candidate value range. In this case, the candidate threshold is 7. The first candidate value range has 7 as its center, with the lower or upper limit being a value obtained by subtracting or adding a specified likelihood value of 2 from or to the center. The mobile terminal 30 accepts the selection of the value 8. In this case, the threshold determination unit determines 8 as the updated call threshold.

[0066] In the flowchart shown in Fig. 8, steps S01 to S03 are the same as the steps in the flowchart shown in Fig. 5. In the first modified example, after step S03, the operation of step S11 is performed.

[0067] In step S11, the presentation unit 26 generates a first candidate value range. The presentation unit 26 presents the first candidate value range on the mobile terminal 30. Note that the mobile 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.

[0068] Thereafter, in step S12, the threshold value determining unit 25 determines whether or not a selection of a value from within the first candidate value range has been accepted via the mobile terminal 30.

[0069] If no value selection is received in step S12, the operation of step S12 is repeated. If a value selection is received in step S12, the operation from step S04 onwards is carried out. Steps S04 and S05 are the same as the steps in the flowchart shown in Figure 5. That is, the call threshold value is determined and updated. Thereafter, the operation of the flowchart ends.

[0070] According to the first modification of the first embodiment described above, the elevator system 1 further includes a presentation unit 26. The presentation unit 26 displays a first candidate value range, including the candidate threshold, on the mobile terminal 30. The threshold determination unit 25 determines a value selected from the first candidate value range as the updated call threshold. For example, a user may desire to increase or decrease the call threshold value from the currently set value based on their walking speed, personality, etc. Specifically, a user with a slow walking speed can increase the call threshold value and delay the timing of call registration for the car 8, allowing them to board the car 8 without worrying that the doors of the car 8 might close. In this case, the first candidate value range is set to include the candidate threshold, making it an appropriate range of values. In this way, users can determine an appropriate call threshold value depending on their individual circumstances.

[0071] Next, a second modification of the first embodiment will be described. Fig. 9 shows an example of a screen displayed on a mobile terminal of the elevator system according to the second modification of the embodiment 1. Note that Fig. 9 does not show the functions of the server device 20.

[0072] In the second modification, the presenting unit 26 generates a second candidate value range instead of the first candidate value range. The second candidate value range is a range of values ​​that can be set as the call threshold. The presenting unit 26 also sets the candidate threshold determined by the candidate determination unit 24 as the recommended value.

[0073] 9, the presentation unit 26 presents the possible threshold value together with the selectable second candidate value range as a recommended value, i.e., displays them on the screen of the mobile terminal 30. In this example, the second candidate value range is a value from 1 to 10, and the possible threshold value is 7.

[0074] After the second candidate value range is displayed by the presentation unit 26, the threshold value determination unit 25 determines the value selected by the user via the mobile terminal 30 as the call threshold value to be updated.

[0075] According to the second modification of the first embodiment described above, the presentation unit 26 displays the second candidate value range and the candidate thresholds on the mobile terminal 30. For example, if only the second candidate value range is presented to the user for selection, the user may be confused about the setting because they do not know the appropriate threshold for their own mobile terminal 30. Furthermore, there is a risk that the user may end up setting the call threshold to an extreme value, such as the smallest value that the user can set. In the elevator system 1 of this modification, the user can set the call threshold to the value they desire while taking into consideration appropriate values.

[0076] Embodiment 2 Fig. 10 is a schematic diagram of a building in which an elevator system according to the second embodiment is installed. 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.

[0077] In the elevator system 1 of the second embodiment, hall radio waves are used as the correction radio waves instead of car radio waves. Although not shown, the result transmitting unit 33 of the mobile terminal 30 generates, as result information, the time transition of the reception strength of the hall radio waves received by the receiving unit 31 when the mobile terminal 30 is present at the hall 4. For example, the result transmitting unit 33 may generate the result information using the reception of the hall radio waves as a starting collection condition.

[0078] The standard index value is calculated based on the reception strength of the hall radio waves when the mobile terminal 30 is present at the hall 4.

[0079] Although not shown, the index value calculation unit 23 may calculate an index value from the result information based on the same criteria as in embodiment 1. At this time, the index value calculation unit 23 may use values ​​obtained by appropriately changing the first determination value, second determination value, first time, second time, advance determination amount, advance time, etc. from those in embodiment 1 in accordance with the situation of each hall 4.

[0080] According to the second embodiment described above, the hall radio waves from the hall beacon 11 are used as the correction radio waves. In this case, as in the first embodiment, the elevator system 1 can calculate the possible threshold value, which is an appropriate call threshold value.

[0081] Although not shown, the hall radio waves included in the result information may be hall radio waves received by the receiver 31 while the mobile terminal 30 is inside the car 8 and the car 8 is moving. In this case, the corrected radio waves are hall radio waves from multiple floor hall beacons, which are hall beacons 11 installed on each floor. The mobile terminal 30 repeatedly approaches and moves away from each of the multiple floor hall beacons. The result information includes a time transition in which the reception strength of the corrected radio waves increases and decreases periodically to some extent. In this case, the index value calculation unit 23 may calculate the maximum value of the reception strength of the corrected radio waves as the index value. Alternatively, the index value calculation unit 23 may calculate the average value of multiple maximum values ​​appearing in the reception strength of the corrected radio waves as the index value. The standard index value may be determined based on a similar value received by the standard terminal and using the same criteria as the index value. Therefore, potential call threshold values ​​can be calculated based on the same condition, i.e., while the car 8 is moving.

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.

[0085] 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.

[0086] 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.

[0087] Some of the functions of server device 20 may be implemented by dedicated hardware 200, and the remaining functions may be implemented by software or firmware. For example, the function of call control unit 22 may be implemented by a processing circuit as dedicated hardware 200, and functions other than the function of call control unit 22 may be implemented by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0088] In this way, the processing circuitry realizes each function of the server device 20 using hardware 200, software, firmware, or a combination of these.
