Description

The present disclosure relates to elevator systems and programs.

Patent Document 1 discloses an elevator system. In this elevator system, when a mobile device carried by a user receives radio waves from a hall beacon installed at the hall, it transmits a call request including the departure floor and destination floor indicating the hall. The elevator system's control panel registers the call request in the car. Therefore, a user can register the departure floor and destination floor in the car simply by going to the hall with their mobile device.

Japanese Patent Publication No. 2021-113125

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 sent unless the reception strength of radio waves from the hall beacon exceeds a call threshold. However, because radio wave reception sensitivity varies depending on the mobile device, there is a risk that the set call threshold value may be inappropriate.

This disclosure has been made to solve the above-mentioned problems. The purpose of this disclosure is to provide an elevator system and program that can calculate an appropriate call threshold.

The elevator system disclosed herein includes an operation control unit that registers calls in the car based on call requests sent 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 car radio waves, which are car radio waves from a car beacon installed in the car, based on the time progression of the reception strength when the corrected car radio waves are received by the mobile terminal; and a candidate determination unit that uses the standard index value and the index value to determine a candidate threshold that is a candidate for the updated call threshold.

The elevator system disclosed herein includes an operation control unit that registers calls in the car based on call requests sent 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 hall radio waves, which are hall radio waves, from the change in reception strength over time when the corrected radio waves are received by the mobile terminal; and a candidate determination unit that uses the standard index value and the index value to determine a candidate threshold that is a candidate for the updated call threshold.

The program disclosed herein causes a computer installed in an elevator system that registers calls in a car based on call requests sent 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 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 uses the standard index value and the index value to determine a candidate threshold that is a candidate for the updated call threshold.

According to the present disclosure, a candidate threshold is determined using an index value calculated from the time progression of the reception strength of the corrected radio wave and a standard index value. This allows an appropriate call threshold to be calculated.

Embodiment 1.
Fig. 1 is a schematic diagram of a building provided with an elevator system according to embodiment 1. Fig. 2 is a diagram showing a landing of the elevator system according to embodiment 1. Fig. 3 is a functional block diagram of the elevator system according to embodiment 1.

In the elevator system 1 of Figure 1, the hoistway 2 passes through each floor of the 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/exit is provided between the landing 4 and the hoistway 2. A landing door 5 is provided at the entrance/exit of each of the plurality of landings 4.

The hoisting machine 6 is provided in a machine room located above the elevator shaft 2. The main rope 7 is wound around the hoisting machine 6. The car 8 is suspended from the main rope 7 inside the elevator shaft 2. The car 8 can move up and down inside the elevator shaft 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 panel 10 is provided in the machine room. As an operation control unit, the control panel 10 can control the overall operation of the elevator shaft 8 by controlling the hoisting machine 6.

The elevator system 1 further includes multiple hall beacons 11, car beacons 12, a server device 20, and a mobile terminal 30.

The multiple platform beacons 11 are installed at several of the multiple platform beacons 4. The platform beacons 11 emit platform radio waves that include an identifier specific to the floor of the platform 4. The platform beacons 11 may be installed at all platform beacons 4, or may be installed only at specific platform beacons 4 out of the multiple platform beacons 4.

The car beacon 12 is installed in the car 8. The car beacon 12 emits car radio waves including an identifier unique to the car 8.

The server device 20 is installed 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.

The mobile terminal 30 is a device capable of displaying information and accepting information input. 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.

Information on the combination of departure floors and destination floors in building 3 is stored in advance in mobile terminal 30. Hereinafter, it is assumed that automatic call mode is set in mobile terminal 30. As 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 destination floor to server device 20 as processing specified in automatic call mode. At this time, the user does not operate mobile terminal 30.

The server device 20 identifies the corresponding control panel 10 from the information included in the call request. The server device 20 sends 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.

When workers install the hall beacon 11, car beacon 12, etc. in the building 3, the workers perform confirmation tasks such as confirming radio wave reception and overall operation. During confirmation tasks, 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 the reception strength of the hall radio waves by the standard terminal exceeds the call threshold when the standard terminal is located within a specified distance from the hall door 5.

The radio wave reception sensitivity of the mobile terminal 30 depends on the model, performance, etc., and is expected to take on a variety of values. Furthermore, the reception sensitivity of the mobile terminal 30 can change depending on the accessories, cover, etc., attached to the mobile terminal 30. Furthermore, as shown in Figure 2, the overall reception sensitivity, which is the strength at which the mobile terminal 30 receives the same radio waves, can 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) can take on a variety of values.

Since the call threshold can be set individually on 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 embodiment 1, an example is 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.

As shown in Figure 3, the mobile terminal 30 has the functions of a receiving unit 31, a call request unit 32, and a result transmitting unit 33. The receiving unit 31 includes an antenna capable of receiving hall radio waves and car radio waves and an antenna control function.

The call request unit 32 is a function realized by a dedicated application and controls the operation of sending call requests. For example, when the automatic call mode is set and the reception strength of the hall radio waves received by the receiver 31 exceeds the call threshold, the call request unit 32 sends a call request to the server device 20.

The result transmission unit 33 collects the time progression 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 transmission unit 33 starts collecting the time progression 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 transmission unit 33 ends collection when the reception strength of the corrected radio waves meets the end collection condition. Thereafter, the result transmission unit 33 creates result information indicating the time progression of the reception strength of the collected corrected radio waves and transmits it to the server device 20. As an example, the result transmission unit 33 ends collection when a specified time has elapsed since the start of collection, as a end collection condition.

The server device 20 has the following functions: a memory unit 21, a call control unit 22, an index value calculation unit 23, a candidate determination unit 24, and a threshold determination unit 25.

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

When the call control unit 22 receives a call request made in the building 3, it uses the database stored in the memory unit 21 to identify the control panel 10 corresponding to the call request. The call control unit 22 sends 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.

The index value calculation unit 23 calculates an index value based on the time progression 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 the adopted section from a specific time to a specific time in the time progression. The index value calculation unit 23 calculates one of the maximum, minimum, or average value of the reception strength in the adopted section and sets it as the index value.

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 progression of the reception strength of the hall radio waves measured using the standard terminal in the building 3 using the same calculation method as the index value. The standard index value may be stored in the memory unit 21, or may be calculated by the index value calculation unit 23 based on information stored in the memory unit 21. The candidate threshold value is a value that is a candidate for the updated call threshold value.

The candidate determination unit 24 calculates the candidate threshold 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 determination unit 24 may determine the candidate threshold 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 determination unit 24 may determine the candidate threshold by multiplying the quotient of the index value divided by the standard threshold by a specified coefficient to the correction value. Alternatively, the candidate determination unit 24 may determine the candidate threshold by selecting a classification value from multiple classification values that corresponds to the magnitude of the index value relative to the standard index value. Specifically, three classification values—high, medium, and low—are prepared as candidate thresholds, and if the difference between the index value and the standard index value is in the range corresponding to the "high" classification value, the "high" classification value is determined as the candidate threshold.

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 also 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.

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

In Figure 4, the vertical axis represents the radio wave reception 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 reception strength of the corrected radio wave received by the mobile terminal 30. The dashed line graph B represents the reception 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.

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.

It is desirable that the reception strength when the mobile terminal 30 and the car 8 are in a similar positional relationship be used as the index value and the standard index value, respectively. Specifically, when car radio waves are used as the correction radio waves, it is desirable that the reception strength when a user is in the car 8 be used as the index value. The index value calculation unit 23 determines the section to be used for calculating the index value by using the slope of the time progression of the reception strength as a value reflecting the positional relationship between the user and the car 8.

The index value calculation unit 23 calculates the change in reception strength between a certain time and a time preceding that time by a specified judgment time as the gradient of the reception strength at each time. That is, a moving average value of the change in reception strength over the judgment time is calculated at each time. The index value calculation unit 23 determines the start point of the adopted section when the change in reception strength over the judgment time exceeds the first judgment value and then falls below the second judgment value. In the example of FIG. 4 , in the section between time _t1 and _t2 , the car 8 moves closer to the mobile terminal 30, causing a sudden increase in reception strength, and the 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, causing the change in reception strength over the judgment time to fall 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.

In addition, in order to reduce the effect 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.

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 as the start point of the adopted period 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 predetermined time has elapsed. In Figure 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.

The adopted interval may be a specified period of time from the starting point, or the last time included in the result information. The index value calculation unit 23 calculates the index value from the reception strength value in the adopted interval.

As shown in graph B, the standard index value may be calculated from the values of the adopted section set using the same criteria as the index value.

In the example of Figure 4, the index value is smaller than the standard index value. In this case, the candidate threshold is calculated to be a value smaller than the reference call threshold.

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.

The flowchart in Figure 5 starts when the mobile terminal 30 completes collection of the time progression of the reception strength of the correction 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. The mobile terminal 30 may also collect 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. The mobile terminal 30 may also collect reception strength and generate result information each time it performs an operation to send a call request when the setting for whether to collect is on.

In step S01, the mobile terminal 30 sends result information to the server device 20.

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.

Then, in step S03, the candidate determination unit 24 calculates a candidate threshold based on the standard index value and the index value calculated in step S02.

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

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

According to the first embodiment described above, the elevator system 1 includes a control panel 10, which is an operation control unit, an index value calculation unit 23, and a candidate determination unit 24. The mobile terminal 30 transmits a call request when the reception strength of the hall radio waves 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.

The standard index value is calculated from the time progression of the reception strength of the standard terminal. The standard terminal is a terminal selected based on prescribed standards. 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 call thresholds can be improved.

In addition, the index value calculation unit 23 determines the start point of the adopted section based on the first judgment quantity, the second judgment quantity, etc. Therefore, in embodiment 1, it is possible to accurately estimate the time period during which the user is in the car 8 from the time progression included in the result information. As a result, it is possible to improve the accuracy of calculating the index value when the situation is the same as the situation when the standard index value was calculated.

In addition, the index value calculation unit 23 may also use a pre-determined amount and a pre-time when determining the start point of the adopted section. This can further improve the accuracy of calculating the index value.

Furthermore, the candidate determination unit 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. Therefore, it is possible to more reliably calculate the candidate threshold, which is an appropriate call threshold.

The 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, if the setting of the call threshold is left to the user, the lowest selectable call threshold may be set, which could result in frequent unnecessary calls and reduced elevator operation efficiency. By automatically updating the appropriate call threshold in the elevator system 1, it is possible to prevent such extreme settings from being made. As a result, it is possible to prevent a decrease in the operation efficiency of the elevator system 1 and improve the convenience of users of the entire elevator system 1.

The elevator system 1 may be any type of elevator that can be operated in response to a call from a mobile terminal 30, 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.

In addition, the collection conditions for terminating the result transmission unit 33 may be when the car 8 arrives at the destination floor, when the passenger disembarks at the destination floor, etc.

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.

As shown in Figure 6, in the first variant, the server device 20 further includes a function of a presentation unit 26. Although not shown, the presentation unit 26 may be provided as a function of the mobile terminal 30, or some of the functions of the presentation unit 26 may be provided in the server device 20 and other functions may be provided in the mobile terminal 30.

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.

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 classification such as "high," "medium," or "low" rather than as a specific numerical value.

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 updated call threshold.

Figure 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 the center, with the lower and upper limits being values obtained by subtracting or adding the specified likelihood value of 2. 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.

In the flowchart shown in Figure 8, steps S01 to S03 are the same as the steps in the flowchart shown in Figure 5. In the first variant, after step S03, the operation of step S11 is performed.

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.

Then, in step S12, the threshold determination unit 25 determines whether or not a selection of a value from the first candidate value range has been received via the mobile terminal 30.

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 performed. Steps S04 and S05 are the same as the steps in the flowchart shown in Figure 5. That is, the call threshold is determined and updated. The operation of the flowchart then ends.

According to the first variant 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 wish to increase or decrease the call threshold from the currently set value, depending on their walking speed, personality, etc. Specifically, a user with a slow walking speed can increase the call threshold and delay the timing of call registration for car 8, allowing them to board car 8 without worrying that the doors of 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 according to their individual circumstances.

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.

In the second variant, the presentation 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. In addition, the presentation unit 26 sets the candidate threshold determined by the candidate determination unit 24 as the recommended value.

As shown in FIG. 9, the presentation unit 26 presents the candidate threshold value along 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 candidate threshold value is 7.

After the second 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 updated call threshold.

According to the second variant of embodiment 1 described above, the presentation unit 26 displays the candidate threshold value on the mobile terminal 30 along with the second candidate value range. 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 will not know the appropriate threshold value for their own mobile terminal 30. There is also a risk that the user may end up with an extreme setting, such as setting the call threshold value to the smallest value they can set. In the elevator system 1 in this variant, the user can set the call threshold value to the value they desire, while taking into account appropriate values.

Embodiment 2.
Fig. 10 is a schematic diagram of a building provided with an elevator system according to the second embodiment. Parts that are the same as or correspond to those in the first embodiment are given the same reference numerals, and a description of these parts will be omitted.

In the elevator system 1 of embodiment 2, hall radio waves are used as the correction radio waves instead of car radio waves. Although not shown, the result transmission unit 33 of the mobile terminal 30 generates result information based on the time progression of the reception strength of the hall radio waves received by the receiving unit 31 when the mobile terminal 30 is located at the hall 4. For example, the result transmission unit 33 may generate result information using the reception of the hall radio waves as the starting collection condition.

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

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. In this case, 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, depending on the situation at each hall 4.

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 a candidate threshold value, which is an appropriate call threshold value.

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 progression in which the reception strength of the corrected radio waves increases and decreases periodically to a certain 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. The index value calculation unit 23 may also 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, a candidate threshold for the call threshold can be calculated based on the same condition, i.e., while the car 8 is moving.

Next, an example of hardware constituting the server device 20 will be described with reference to FIG.
FIG. 11 is a hardware configuration diagram of the server device of the elevator system according to the first or second embodiment.

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.

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 at least one memory 100b.
