Fig. 14 is a diagram showing an example of a configuration for realizing the functions of the elevator monitoring device.

[0017] As shown in Fig. 1, the elevator system according to this embodiment includes an elevator 200, an elevator monitoring device 100, and a terminal device 300. The elevator 200 has a plurality of cars 210 and a control device 220. Fig. 2 is a schematic diagram of an example of the elevator 200 included in the elevator system according to this embodiment. A building in which the elevator 200 is installed has the same number of hoistways as the number of cars 210. Each of the plurality of cars 210 is disposed in each hoistway so as to be able to rise and fall freely. The car 210 rises and falls in the hoistway, and transports passengers and the like boarding in the car 210 between the plurality of floors of the building.

[0018] The control device 220 controls the overall operation of the elevator, including the operation of the cars 210. The multiple cars 210 are divided into one or more banks and managed. Two or more cars 210 belong to one bank. In the example shown in Fig. 2, the elevator 200 has one bank, and two cars 210 belong to this one bank. The control device 220 manages the multiple cars 210 belonging to the same bank as a group.

[0019] A platform call button (not shown) is provided at each floor platform where the car 210 can stop. The platform call button is for passengers to register a platform call. By operating the platform call button, a passenger can register a platform call to call the car 210 in the desired travel direction to that floor. In addition, a destination floor button (not shown) is provided inside the car 210. The destination floor button is for passengers to register a car call. By operating the destination floor button once a passenger has boarded the car 210, a car call with the desired floor as the destination can be registered.

[0020] When a hall call is registered, the control device 220 determines a car 210 to be assigned to the hall call. Then, the control device 220 runs the assigned car 210 to the floor where the hall call is registered. Also, when a car call is registered by a passenger who has boarded the car 210, the control device 220 runs the car 210 to the destination floor of the car call.

[0021] The elevator monitoring device 100 is provided for a user, such as a manager or maintenance worker of the elevator 200, to monitor the operation status of the elevator 200. The elevator monitoring device 100 is provided so as to be able to communicate with a control device 220 of the elevator 200. The communication between the elevator monitoring device 100 and the control device 220 may be wired or wireless.

[0022] As shown in Fig. 1, an elevator monitoring device 100 according to this embodiment includes a storage unit 120, a calculation unit 130, and a display control unit 150. The storage unit 120 stores passenger boarding / alighting information and call information at each floor for each of a plurality of cars 210 of an elevator 200. The elevator monitoring device 100 acquires operation information of each car 210 from a control device 220 of the elevator 200. The operation information of the car 210 acquired by the elevator monitoring device 100 includes call information of each car 210 and passenger boarding / alighting information at each floor. In the example described here, the control device 220 of the elevator 200 periodically transmits the following information to the elevator monitoring device 100 as operation information of the car 210.

[0023] Bank ID Unit ID · Running status of car 210 (running / stopped) · Load of 210 cages · Car call registration status (car call occurrence / completion) · Destination floor of car call

[0024] Here, the bank ID is an ID that identifies one of the multiple banks that the elevator 200 has. The car ID is an ID that identifies one of the multiple cars 210 that belong to the bank identified by the bank ID. Furthermore, the load of the car 210 is the weight of the object loaded in the car 210. The load of the car 210 is measured, for example, by a weighing device or the like provided in the car 210. Unless heavy baggage or the like is loaded in the car 210, the weight of the object loaded in the car 210 can be considered to be the total weight of the passengers riding in the car 210.

[0025] The elevator monitoring device 100 monitors the operation information of the car 210 transmitted from the control device 220 of the elevator 200. Then, the storage unit 120 of the elevator monitoring device 100 stores the call information of each car 210 and the boarding and alighting information of the passengers at each floor based on the operation information of the car 210. In the example described here, the storage unit 120 stores the call information of each car 210 and the boarding and alighting information of the passengers at each floor as a database. Specifically, when a new car call is registered in the elevator 200, that is, when a new car call is generated, the elevator monitoring device 100 creates a new record consisting of the following fields and registers it in the database of the storage unit 120. FIG. 3 shows an example of a table of the database stored in the storage unit 120.

[0026] Time when the car call occurred Bank ID Unit ID · Destination floor of car call - Car load before disembarking - Car load after disembarking Number of passengers getting off

[0027] Of these fields, the time when the car call was generated and the destination floor of the car call correspond to the call information of the car 210. Also, the car load before alighting, the car load after alighting, and the number of alighting passengers correspond to boarding and alighting information at each floor of the car 210. Note that the values ​​of the car load before alighting, the car load after alighting, and the number of alighting passengers are null at the time of record creation, that is, a record is created with nothing stored in these fields.

[0028] When the car 210 arrives at the destination floor of the car call, the control device 220 of the elevator 200 transmits a signal to the elevator monitoring device 100 to notify the completion of the car call. The storage unit 120 stores the value of the load of the car 210 at the time when the elevator monitoring device 100 receives the signal to notify the completion of the car call, i.e., before passengers disembark from the car 210, as the value of the car load before disembarkation of the record. In other words, the storage unit 120 updates the value of the car load before disembarkation of the record from null to the value of the load of the car 210 at the time when the elevator monitoring device 100 receives the signal to notify the completion of the car call.

[0029] When passengers have finished disembarking from the car 210 and the car 210 starts traveling to the next floor, the control device 220 of the elevator 200 transmits a signal to the elevator monitoring device 100 notifying that the car is traveling. The storage unit 120 stores the value of the load of the car 210 at the time when the elevator monitoring device 100 receives the signal notifying that the car is traveling, i.e., after the passengers have disembarked from the car 210, as the value of the post-disembarkation car load of the record. In other words, the storage unit 120 updates the value of the post-disembarkation car load of the record from null to the value of the load of the car 210 at the time when the elevator monitoring device 100 receives the signal notifying that the car is traveling.

[0030] When the values ​​of the car load before alighting and the car load after alighting of the record are updated from null, the storage unit 120 updates the value of the number of alighting passengers of the record. The number of alighting passengers can be calculated by dividing the difference between the car load before alighting and the car load after alighting by the average body weight. Here, the value of the average body weight is preset. The user of the elevator monitoring device 100 can operate the terminal device 300 described later, for example, to estimate the average body weight of the building users from the tendency of the users of the building in which the elevator 200 is installed, that is, the ratio of the users of the building by gender and age, and set it in advance in the elevator monitoring device 100. The storage unit 120 updates the value of the number of alighting passengers of the record from null to a value obtained by dividing the difference between the car load before alighting and the car load after alighting of the record by the average body weight.

[0031] The terminal device 300 is a PC, a smartphone, a tablet terminal, or the like used by a user of the elevator monitoring device 100. The terminal device 300 includes a display unit 310 and an operation unit 320. The display unit 310 is a liquid crystal display or the like capable of displaying various information to the user. The operation unit 320 is a keyboard, a mouse, or the like for the user to input various information. The terminal device 300 may include a touch panel that serves both as the display unit 310 and the operation unit 320. The terminal device 300 is capable of communicating with the elevator monitoring device 100. The communication between the elevator monitoring device 100 and the terminal device 300 may be wired or wireless.

[0032] The elevator monitoring device 100 according to this embodiment can provide a user with information relating to the operation efficiency of the elevator 200. When checking information relating to the operation efficiency of the elevator 200, the user operates the operation unit 320 of the terminal device 300 to input information specifying one or more target cars 210. Here, the user inputs the bank ID and car ID of the elevator 200 into the terminal device 300 to specify one or more target cars 210.

[0033] Furthermore, the user operates the operation unit 320 of the terminal device 300 to input information specifying the target period. For example, the user specifies the target period by inputting a start date and time and an end date and time into the terminal device 300. Note that the target period does not have to be one continuous period, but may be two or more intermittent periods. Also, the same time period on different days, for example, the morning work time, the afternoon time, the evening work time, etc., may be specified as the target period.

[0034] The information specifying the car 210 and the information specifying the period input to the terminal device 300 are transmitted from the terminal device 300 to the elevator monitoring device 100. The calculation unit 130 of the elevator monitoring device 100 calculates a usage index value for each floor of the specified car 210 within the specified period, based on the passenger boarding / alighting information and call information stored in the memory unit 120. The usage index value for each floor is an index value that indicates the usage status of each floor. In the example described here, the usage index value for each floor is the average number of passengers alighting on each floor.

[0035] The calculation unit 130 tally up the total number of car calls (also referred to as the total number of car calls) that occurred within a specified period for a specified car 210 and the total number of people who got off (also referred to as the total number of people who got off) from the records stored in the memory unit 120. The calculation unit 130 performs this tallying up for each floor of the building. Then, the calculation unit 130 divides the total number of people who got off by the total number of car calls to calculate the average number of people who got off per car call on each floor.

[0036] The display control unit 150 causes the display unit 310 of the terminal device 300 to display the average number of alighting passengers, i.e., the utilization index value, calculated by the calculation unit 130 as described above. The display control unit 150 generates a display control signal for displaying the average number of alighting passengers. The display control signal generated by the display control unit 150 is transmitted from the elevator monitoring device 100 to the terminal device 300. In accordance with the received display control signal, the terminal device 300 causes the display unit 310 to display the average number of alighting passengers at each floor of the specified car 210 within a specified period of time.

[0037] At this time, the display control unit 150 may display the average number of passengers alighting at each floor as a numerical value as it is, or may use a so-called color scale to represent the number of passengers in color and display the visualized number. An example of the case where the average number of passengers alighting at each floor is visualized and displayed using color is shown in FIG. 4. As shown in the figure, a different color is assigned to each section of the average number of passengers alighting, and the average number of passengers alighting at each floor is represented by color. The higher the average number of passengers alighting, the higher the operation efficiency, and the lower the average number of passengers alighting, the lower the operation efficiency. The user may be allowed to set in advance one or both of the threshold value that is the boundary between sections and the color for each section. In this case, the user sets the threshold value that is the boundary between sections and the color for each section using, for example, the terminal device 300, etc.

[0038] Next, an example of the operation of the elevator monitoring device 100 configured as above will be described with reference to the flow diagram of Fig. 5. First, in step S10, the elevator monitoring device 100 acquires operation information of the car 210 from the control device 220 of the elevator 200, and stores it in the memory unit 120. Then, every time the car 210 responds to a car call, the memory unit 120 calculates and stores the number of passengers who have disembarked from the car 210 based on the change in the load of the car 210. In the following step S11, the user specifies the target car 210 and the period from, for example, the terminal device 300. After step S11, the elevator monitoring device 100 next performs the process of step S12.

[0039] In step S12, the calculation unit 130 tallies the total number of car calls and the total number of alighting passengers for the specified car 210 within the specified period from the records stored in the memory unit 120 in step S10. Then, the calculation unit 130 divides the total number of alighting passengers by the total number of car calls to calculate the average number of alighting passengers per car call for each floor. In the following step S13, the display control unit 150 causes the display unit 310 of the terminal device 300 to display the visualization result of the operation efficiency of the elevator 200, i.e., the average number of alighting passengers calculated in step S12. When the processing of step S13 is completed, the series of operations ends.

[0040] According to the elevator monitoring device 100 and elevator system configured as described above, by calculating and displaying a utilization index value, such as the average number of people getting off at each floor per car call, the operation efficiency of the elevator 200 can be visualized, and the manager of the elevator 200, etc. can be assisted in understanding the operation efficiency of the elevator 200.

[0041] The elevator monitoring device 100 according to this embodiment may further include a setting unit 110 and an update unit 140, as shown in Fig. 1. The setting unit 110 sets whether or not to perform service disconnection for each floor for each of the multiple cars 210 of the elevator 200. Then, when the setting state of the service disconnection by the setting unit 110 is changed from the first setting state to the second setting state, the update unit 140 updates the usage index value calculated by the calculation unit 130 to the usage index value in the second setting state. The second setting state is a setting state different from the first setting state. In this case, the display control unit 150 causes the display unit 310 of the terminal device 300 to display the usage index value updated by the update unit 140.

[0042] As shown in FIG. 2, if each of the multiple cars 210 in the same bank can stop at all floors of a building, passengers boarding the cars 210 tend to be dispersed. In particular, if the cars 210 stop at each floor and a small number of passengers get off, the operation efficiency of the elevator 200 decreases. In response to this, as shown in the example of FIG. 6, a so-called floor lockout function is used to limit the floors at which each of the multiple cars 210 in the same bank can stop, so that the transportation of passengers is shared among the multiple cars 210 and each car 210 can transport passengers collectively, thereby improving the operation efficiency of the elevator 200. However, depending on the number of users of the elevator 200, there are cases in which the negative effects of floor lockout, such as increased waiting time, are greater.

[0043] According to the elevator monitoring device 100 equipped with the setting unit 110 and the update unit 140, if the setting state of the service disconnection of each car 210 is changed by the setting unit 110, the utilization index value calculated by the calculation unit 130 can be updated to the utilization index value after the setting change by the update unit 140. Here, the setting of the service disconnection by the setting unit 110 is basically effective only in the elevator monitoring device 100, and is not reflected in the actual control of the elevator 200. Therefore, the user can confirm the change in the operation efficiency of the elevator 200 when the floor lockout setting is changed, without actually performing the service disconnection, i.e., floor lockout, in the elevator 200. Note that, for example, the setting of the service disconnection by the setting unit 110 may be transmitted from the elevator monitoring device 100 to the control device 220 of the elevator 200 by the user performing a predetermined reflection operation, so that the setting can be reflected in the actual control of the elevator 200.

[0044] Next, the details of the update of the usage index value by the update unit 140 will be described by taking as an example a case where the usage index value of each floor is the average number of passengers alighting at each floor. Here, the above-mentioned second setting state is a setting state in which at least one of the floors set to not disconnect the service in the above-mentioned first setting state is changed to a setting to disconnect the service. For example, such a case applies when the first setting state is a state in which floor lockout is not performed, and the second setting state is a state in which floor lockout is performed. In this case, the update unit 140 uses the usage index value (average number of passengers alighting) of the floor set to not disconnect the service in the second setting state by using the usage index value (average number of passengers alighting) of the floor set to not disconnect the service in the second setting state.

[0045] For example, as the second setting state, as shown in Fig. 7, a setting is made such that for the car 210 with the car ID of PE1, lockout (service disconnection) is performed for floors G to 3, and for the car 210 with the car ID of PE2, lockout (service disconnection) is performed for floors 4 to 6. The first setting state before the setting change is a state in which floor lockout is not performed for both the cars 210 with the car IDs of PE1 and PE2.

[0046] The user inputs the setting contents of such service disconnection, for example, by operating the operation unit 320 of the terminal device 300. The setting contents of service disconnection input to the terminal device 300 are transmitted from the terminal device 300 to the elevator monitoring device 100. The setting unit 110 of the elevator monitoring device 100 sets, in accordance with the setting contents received by the elevator monitoring device 100, for each of the multiple cars 210 of the elevator 200, whether or not to disconnect the service for each floor.

[0047] The update unit 140 specifies whether disembarking is possible or not for each floor of each car 210 based on the service disconnection setting by the setting unit 110. Note that disembarking is not permitted for a floor for which service disconnection (lockout) is set for the car 210. Also, disembarking is permitted for a floor for which service disconnection (lockout) is not set for the car 210 or for which service disconnection (lockout) has been released.

[0048] The update unit 140 acquires the calculation result of the calculation unit 130 as the average number of passengers alighting at each floor of each car 210 before the setting change, i.e., in the first setting state. Then, as shown in Fig. 9, the update unit 140 adds the average number of passengers alighting at floors where alighting is not permitted for a certain car 210 to the average number of passengers alighting of other cars 210 that belong to the same bank as the car 210 and are alighting permitted at the floor. At this time, if there are multiple other cars 210 that are alighting permitted at the floor, the average number of passengers alighting of the cars 210 that are alighting prohibited is evenly distributed to the multiple cars 210 that are alighting permitted. In this way, the update unit 140 updates the average number of passengers alighting in the first setting state calculated by the calculation unit 130 to the average number of passengers alighting in the second setting state.

[0049] Alternatively, the update unit 140 may calculate the average number of alighting passengers in the second setting state by aggregating the total number of alighting passengers and the total number of car calls within a specified period instead of the average number of alighting passengers. In this case, the update unit 140 may aggregate the total number of car calls and the total number of alighting passengers for each car 210 within a specified period from the records stored in the storage unit 120. Alternatively, the update unit 140 may obtain the total number of alighting passengers by multiplying the average number of alighting passengers in the first setting state calculated by the calculation unit 130 by the total number of car calls within a specified period aggregated from the records stored in the storage unit 120.

[0050] Then, the update unit 140 adds the total number of passengers alighting at a floor where alighting is not permitted for a certain car 210 to the total number of passengers alighting at another car 210 belonging to the same bank as the car 210 and permitting alighting at the floor. At this time, if there are multiple other cars 210 permitting alighting at the floor, the total number of passengers alighting at the car 210 where alighting is not permitted is evenly distributed to the multiple cars 210 permitting alighting. In this way, the total number of passengers alighting reflecting the lockout is calculated. The update unit 140 divides the total number of passengers alighting after distribution by the total number of car calls to calculate the average number of passengers alighting after the setting change, i.e., in the second setting state. In this way, the update unit 140 updates the average number of passengers alighting in the first setting state calculated by the calculation unit 130 to the average number of passengers alighting in the second setting state.

[0051] Here, the boarding / alighting information and call information of passengers at each floor stored in the storage unit 120 is for the elevator 200 in a state where lockout is not set, i.e., in a first setting state. In this manner, the update unit 140 can simulate a situation where a lockout is set using the boarding / alighting information and call information of passengers at each floor of the elevator 200 in a state where lockout is not set, and calculate the average number of passengers alighting when a lockout is set.

[0052] The update unit 140 may determine whether the calculated average number of passengers alighting in the second setting state satisfies the condition of the transport capacity of the elevator 200. That is, for each car 210, the update unit 140 determines whether the sum of the average number of passengers alighting at each floor in the second setting state is equal to or less than the capacity (maximum capacity) of the car 210. Then, when there is a car 210 in which the sum of the average number of passengers alighting at each floor in the second setting state exceeds the capacity of the car 210, the update unit 140 may determine that the transport capacity of the elevator 200 is insufficient and generate an alert to prompt the user to reset the service disconnection. FIG. 10 shows an example in which the maximum capacity is exceeded in the car 210 with the car ID PE2 as a result of distributing the number of passengers alighting in the car 210 with the lockout set to the car 210 without the lockout set in the simulation.

[0053] The display control unit 150 causes the display unit 310 of the terminal device 300 to display the average number of alighting passengers in the second setting state calculated by the update unit 140 as described above, i.e., the usage index value. At this time, as shown in Fig. 11, the display control unit 150 may cause the display unit 310 to display both the average number of alighting passengers in the first setting state calculated by the calculation unit 130 and the average number of alighting passengers in the second setting state updated by the update unit 140. In this way, the user can visually grasp the change in the average number of alighting passengers due to the change in the lockout setting, and can easily compare the average number of alighting passengers before and after the setting change.

[0054] Furthermore, the simulation result by the update unit 140, i.e., the average number of alighting passengers in the second setting state calculated by the update unit 140, may be stored in the storage unit 120 of the elevator monitoring device 100. Then, when the lockout setting is further changed from the second setting state, the display control unit 150 may cause the display unit 310 to display the average number of alighting passengers in the second setting state that has been stored and the average number of alighting passengers after the setting has been further changed, as shown in Fig. 12. In this way, the user can easily grasp the re-simulation result in which the setting has been further changed, based on the simulation result by the update unit 140.

[0055] Next, an example of the operation of the elevator monitoring device 100 configured as above will be described with reference to the flow diagram of FIG. 13. First, in step S20, the calculation unit 130 of the elevator monitoring device 100 calculates the average number of alighting passengers before the lockout setting is changed, i.e., in the first setting state. Then, the display control unit 150 displays the calculated average number of alighting passengers on the display unit 310 of the terminal device 300, thereby visualizing the operation efficiency of the elevator 200. Details of this operation are as shown in the flow diagram of FIG. 5. In the following step S21, the user inputs the setting contents of the service disconnection specifying the lockout target floor to, for example, the terminal device 300. Then, the setting unit 110 of the elevator monitoring device 100 sets whether or not to disconnect the service for each floor for each of the multiple cars 210 of the elevator 200 according to the setting contents. After step S21, the elevator monitoring device 100 next performs the process of step S22.

[0056] In step S22, the update unit 140 specifies whether disembarking is possible or not for each floor of each car 210 based on the service separation setting in step S21. In the following step S23, the update unit 140 distributes the number of passengers disembarking at a floor where disembarking is not possible for a certain car 210 to another car 210 that belongs to the same bank as the car 210 and is allowed to disembark at the floor. Then, the update unit 140 calculates the average number of passengers disembarking after the setting change, i.e., in the second setting state, based on the distributed number of passengers disembarking. After step S23, the elevator monitoring device 100 next performs the process of step S24.

[0057] In step S24, the update unit 140 determines whether the average number of alighting passengers in the second setting state calculated in step S23 satisfies the condition of the transport capacity of the elevator 200. That is, the update unit 140 checks whether the total of the distributed number of alighting passengers for each car 210 is equal to or less than the capacity (maximum capacity) of the car 210. If this check shows that there is a car 210 whose total of the distributed number of alighting passengers exceeds the capacity of the car 210, the elevator monitoring device 100 returns to step S21 and continues the process. On the other hand, if there is no car 210 whose total of the distributed number of alighting passengers exceeds the capacity of the car 210, the elevator monitoring device 100 next performs the process of step S25.

[0058] In step S25, the display control unit 150 displays the simulation result after the lockout setting change, i.e., the average number of people getting off in the second setting state calculated in step S23, on the display unit 310 of the terminal device 300. When the process of step S25 is completed, the series of operations ends.

[0059] According to the elevator monitoring device 100 and elevator system configured as described above, by including the setting unit 110 and the update unit 140, etc., it is possible to visualize the change in the operation efficiency of the elevator 200 when the floor lockout setting is changed, without actually disconnecting the service, i.e., locking out the floor, in the elevator 200. This makes it possible to support the manager of the elevator 200 in setting the lockout.

[0060] In the above, a configuration example has been described in which the display unit 310 and the operation unit 320 are provided in the terminal device 300, and the user inputs and understands various information related to the elevator monitoring device 100 via the terminal device 300. However, one or both of the display unit 310 and the operation unit 320 may be provided in the elevator monitoring device 100, not in the terminal device 300. In this way, the user can directly input information to the elevator monitoring device 100 and directly check information output from the elevator monitoring device 100.

[0061] FIG. 14 is a diagram showing an example of a configuration for realizing the functions of the elevator monitoring device 100 in this embodiment. The functions of the elevator monitoring device 100 are realized, for example, by a processing circuit. The processing circuit may include a processor 101 and a memory 102. The processing circuit may be dedicated hardware 103. A part of the processing circuit may be formed as the dedicated hardware 103, and the processing circuit may further include the processor 101 and the memory 102. In the example shown in the figure, a part of the processing circuit is formed as the dedicated hardware 103. Also, in the example shown in the figure, the processing circuit further includes the processor 101 and the memory 102.

[0062] The processing circuitry, part of which is at least one dedicated hardware 103, may be, for example, a single circuit, a multiple circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. If the processing circuitry comprises at least one processor 101 and at least one memory 102, the functionality of the elevator monitoring device 100 may be realized by software, firmware, or a combination of software and firmware.

[0063] The software and firmware are written as programs and stored in memory 102. Processor 101 realizes the functions of each unit by reading and executing the programs stored in memory 102. Processor 101 is also called a CPU (Central Processing Unit), central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. Memory 102 corresponds to, for example, non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, and EEPROM, or a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a DVD.

[0064] In this way, the processing circuit of the elevator monitoring device 100 can realize each function of the elevator monitoring device 100 by hardware, software, firmware, or a combination of these. When the processing circuit of the elevator monitoring device 100 includes at least the processor 101 and the memory 102, the processor 101 executes a program stored in the memory 102 in the elevator monitoring device 100, and the hardware and software of the elevator monitoring device 100 work together to realize the functions of each unit included in the elevator monitoring device 100.

[0065] The elevator monitoring method according to this embodiment is executed by the computer of the elevator monitoring device 100. As is clear from the above description, the elevator monitoring method according to this embodiment includes at least a storage step, a calculation step, and a display step. In the storage step, the boarding / alighting information and call information of passengers at each floor are stored in the storage unit 120 for each of the multiple cars 210 of the elevator 200 having the multiple cars 210. In the calculation step, the calculation unit 130 calculates the average number of passengers alighting at each floor of the specified car 210 during a specified period based on the boarding / alighting information and call information of passengers stored in the storage unit 120 in the storage step. In the display step, the average number of passengers alighting calculated by the calculation unit 130 in the calculation step is displayed on the display unit 310.

[0066] Alternatively, as is clear from the above description, the elevator monitoring method according to this embodiment includes at least a storage step, a calculation step, a setting step, an update step, and a display step. In the storage step, for each of the multiple cars 210 of the elevator 200 having the multiple cars 210, the boarding / alighting information of users and the call information at each floor are stored in the storage unit 120. In the calculation step, the calculation unit 130 calculates a usage index value indicating the usage status of the specified car 210 at each floor during a specified period based on the boarding / alighting information and the call information of users stored in the storage unit 120 in the storage step. In the setting step, the setting unit 110 sets whether or not to disconnect the service for each floor for each of the multiple cars 210. In the update step, when the setting state of the service disconnection is changed from the first setting state to the second setting state by the setting unit 110 in the setting step, the update unit 140 updates the usage index value calculated by the calculation unit 130 in the calculation step to the usage index value in the second setting state. In the display step, the utilization index value updated by the update unit 140 in the update step is displayed on the display unit.
