Description

[Technical field]

[0001] An embodiment of the present invention relates to an elevator operation control adjustment device and program. [Background technology]

[0002] Elevators do not always operate in a way that satisfies elevator users. In order to reduce the dissatisfaction of elevator users, it is generally necessary for the building manager or owner (hereinafter referred to as "manager, etc.") to collect the requests of elevator users and decide how to change the control. For example, there is a known technology in which a control that is emphasized is manually selected from pre-prepared control options such as "reducing the number of people waiting for a long time," "increasing the number of calls that are answered quickly," and "increasing the reservation success rate," and the selected control is applied to the operation of the elevator.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 01-231778 [Patent Document 2] Patent Publication No. 2021-080077 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional method, it is difficult to resolve users' dissatisfaction because the manager who changes the control settings does not understand the opinions of actual elevator users, or the timing of the setting change may be too early or too late. In addition, the manager must manually change the control settings while being aware of the dissatisfaction of elevator users, or request the change from the elevator company, which is a cumbersome and burdensome task.

[0005] The problem to be solved by the invention is to provide an elevator operation control adjustment device and program that can reduce user dissatisfaction and ease the burden on managers and the like. [Means for solving the problem]

[0006] The elevator operation control adjustment device according to the embodiment includes: an information management unit that manages information in which words expressing various dissatisfaction levels are associated with controls that reduce the various dissatisfaction levels for each elevator operation state; A voice collecting unit that collects voices uttered by elevator users at the elevator hall or inside the elevator car, and words expressing dissatisfaction included in the voices collected by the voice collecting unit. and elevator operation status To The corresponding control and an operation control adjustment unit that is applied to the operation of the elevator.

[0008] Hereinafter, an embodiment will be described with reference to the drawings.

[0009] <Elevator system configuration> FIG. 1 is a block diagram showing an example of the configuration of an elevator group control system according to an embodiment.

[0010] The elevator group management system shown in FIG. 1 includes an elevator group management control device 20, elevator control devices 11a-11c and cars 12a-12c that constitute a plurality of elevators, and a hall call registration device 15 and sound collecting microphones 16a-16c installed in a hall (elevator hall) 14 on each floor.

[0011] Here, an example is shown in which three elevators, A to C, are group-controlled. The elevators A to C correspond to three elevator control devices 11a to 11c, three cars 12a to 12c, and three sound collecting microphones 16a to 16c, respectively.

[0012] The elevator control devices 11a to 11c are provided for each of the elevator cars 12a to 12c, and control the operation of the corresponding elevator cars. Specifically, the elevator control devices 11a to 11c control motors (hoists) (not shown) for raising and lowering the elevator cars 12a to 12c, and control the opening and closing of doors. These elevator control devices 11a to 11c are configured using a computer.

[0013] The cars 12a to 12c are driven by motors to move up and down in the elevator shaft. The cars 12a to 12c are provided with load sensors 13a to 13c for detecting the load inside the cars, respectively. Load data detected by the load sensors 13a to 13c is transmitted to the group management control device 20 via the elevator control devices 11a to 11c.

[0014] In addition, sound collecting microphones 18a to 18c are installed in the elevator cars 12a to 12c, respectively. The sound collecting microphones 18a to 18c collect the voices of the elevator users in the cars. The collected voices of the elevator users are transmitted to the operation control adjustment device 22 in the group management control device 20 through the elevator control devices 11a to 11c.

[0015] The group management control device 20 is a device for group management and control of the operation of a plurality of cars 12a to 12c, and is configured using a computer similar to the elevator control devices 11a to 11c. In this embodiment, the group management control device 20 is equipped with a call storage unit 21, an operation control adjustment device 22, and an operation control unit 23. Note that, although an example in which the operation control adjustment device 22 is provided inside the group management control device 20 is shown here, the operation control adjustment device 22 may also be provided outside the group management control device 20. A specific example in that case will be described later.

[0016] The call storage unit 21 stores hall calls registered by the operation of the hall call registration device 15. The operation control adjustment device 22 instructs the operation control unit 23 to implement control for reducing dissatisfaction of elevator users based on words expressing dissatisfaction contained in voices collected from the sound collection microphones 16a to 16c and the sound collection microphones 18a to 18c. The operation control adjustment device 22 is configured to communicate with the information terminal 10 held by the manager or the like and the information terminal 11 held by each elevator user via a communication network not shown. The manager or the like can use the information terminal 10 to view and change the contents (hereinafter referred to as "viewing, etc.") of information managed by the operation control adjustment device 22. In some cases, the device may be configured so that the elevator users can view part of the information managed by the operation control adjustment device 22 using the information terminal 11.

[0017] The operation control adjustment device 22 is configured using a computer, and various functions of the operation control adjustment device 22 are realized as programs executed by the computer. The various functions of the operation control adjustment device 22 will be described in detail later.

[0018] The operation control unit 23 controls the operation of multiple elevators through the elevator control devices 11a to 11c. If there is no instruction from the operation control adjustment device 22, the operation control unit 23 performs general group management control, but if the operation control adjustment device 22 instructs the operation control unit 23 to perform a certain control, the operation control unit 23 performs the control with priority.

[0019] When a new hall call is registered, the operation control unit 23 selects an elevator from among the elevators 12a to 12c to which the hall call should be assigned, and causes the elevator to respond to the corresponding hall 14 (causing the elevator to head toward the hall 14 at the floor where the hall call is registered).

[0020] FIG. 2 is a diagram showing an example of the configuration of the hall 14. As shown in FIG. A hall call registration device 15 for registering hall calls is installed at a hall (elevator hall) 14 on each floor. In the example of FIG. 2, a hall call registration device 15 installed on an arbitrary floor is shown for convenience, but in reality, at least one hall call registration device 15 is installed on each floor. The hall call registration device 15 is connected to the group management control device 20 via a transmission cable (not shown). The hall call registration device 15 has a direction button (also called a "hall call button") that allows an elevator user to specify a destination direction (upward / downward).

[0021] Here, a "hall call" is a call signal registered by operating a direction button at a platform, and includes information on the registered floor and destination direction. On the other hand, a "car call" is a call signal registered by operating a destination floor button in a car, and includes information on the car and the destination floor.

[0022] In addition, at the landing (elevator hall) 14 of each floor, sound collecting microphones 16a to 16c are installed for each elevator. The sound collecting microphones 16a to 16c are installed near the landing doors 17a to 17c, respectively, and collect the voices of multiple elevator users waiting in front of the arrival gates of the cars 12a to 12c. The collected voices of the elevator users are transmitted to an operation control adjustment device 22 in the group management control device 20.

[0023] Next, one of the cars 12a to 12c will be referred to as the car 12 for convenience, and the internal configuration of the car 12 will be described.

[0024] 3 is a diagram showing a configuration example of the vicinity of the entrance / exit inside the car 12. However, this is just one example, and the present invention is not limited to this example.

[0025] A car door 40 is provided at the entrance of the car 12 so as to be able to be opened and closed freely. In the example of Fig. 3, a car door 40 of a double-opening type is shown, and two door panels 40a, 40b constituting the car door 40 open and close in opposite directions along the width direction (horizontal direction).

[0026] Entrance pillars 41a, 41b are provided on both sides of the entrance of the car 12. In the example of Fig. 3, when the car door 40 is opened, one door panel 40a is stored in a door pocket 42a provided on the back side of the entrance pillar 41a, and the other door panel 40b is stored in a door pocket 42b provided on the back side of the entrance pillar 41b.

[0027] In addition, a display 43, an operation panel 45 on which a destination floor button 44 and the like are arranged, and a speaker 46 are installed on one or both of the entrance columns 41a and 41b. In the example of FIG. 3, the speaker 46 and a sound collection microphone 18, which is one of the above-mentioned sound collection microphones 18a to 18c, are installed on the entrance column 41a, and the display 43 and the operation panel 45 are installed on the entrance column 41b. When an elevator user who has entered the car 12 presses the destination floor button 44 on the operation panel 45, the destination floor designated by the destination floor button 44 is registered as a car call. The car call registered in the car 12 is sent to the group management control device 20 via the elevator control device 11 corresponding to the car 12.

[0028] <Functional configuration of the operation control adjustment device 22> The operation control adjustment device 22 in the group management control device 20 shown in Figure 1 has, as various functions, a voice collection unit 22a, a voice analysis unit 22b, an information management unit 22c, a conversation classification unit 22d, an occurrence frequency calculation unit 22e, a situation determination unit 22f, an operation control adjustment unit 22g, and a reconfiguration processing unit 22h.

[0029] The voice collection unit 22a separately collects the voices collected by the voice collection microphones 16a to 16c installed for each car at the boarding area on each floor, and also separately collects the voices collected by the voice collection microphones 18a to 18c for each car, and records the data of each collected voice in a specified memory area.

[0030] The voice analysis unit 22b converts each piece of voice data collected by the voice collection unit 22a into text and performs morphological analysis or the like to extract (detect) each word.

[0031] The information management unit 22c sets and manages association information that associates in advance words expressing various types of dissatisfaction with controls that reduce each type of dissatisfaction.

[0032] Fig. 4 shows an example of the association information set and managed by the information management unit 22c. However, the association information shown in Fig. 4 is only an example and is not limited to this example. The configuration of the association information may be changed as appropriate.

[0033] The association information shown in FIG. 4 has various setting items such as "elevator operation state", "word", "control", "threshold value", and "performance record".

[0034] An "elevator operation state" indicates an elevator operation state that is assumed when a corresponding "word" is uttered as a voice by an elevator user. A "word" indicates a word that an elevator user is assumed to utter when feeling dissatisfied in the corresponding "elevator operation state," and a "control" indicates a control that is effective in reducing or eliminating the dissatisfaction.

[0035] In addition, the "words" may be managed separately into words related to conversations at the "boarding area" and words related to conversations "inside the car."

[0036] Examples of the "elevator operating state" include "before responding to a hall call and the doors are open" (before responding to a hall call and the doors are open), "when responding to a hall call and the doors are open" (before responding to a hall call and the doors are open), "responding to a registered car call floor" (while responding to a registered car call floor), etc.

[0037] For example, if the "elevator operating state" is "before responding to a hall call and before the doors open" (before responding to a hall call and before the doors open) and the "word" is "missed, came first, ..." (words uttered when, contrary to expectations, a car of a car number other than the one predicted by a lantern or the like lands on the ground), the corresponding "control" is "action to prevent other cars from arriving first" (action to prevent a car of a car number other than the one scheduled to land on the ground from arriving first).

[0038] Also, if the "elevator operation state" is "doors open in response to a platform call" (before a platform call is responded to and the doors are open), and the "word" is "can't get on, ..." (a word uttered when a passenger tries to get on a car that has landed at the ground but cannot because it is full), the corresponding "control" is "automatic dispatch of another car to the detected floor" (directing the car of another car to the floor where the platform call was made).

[0039] Also, if the "elevator operating state" is "before answering a hall call and before the doors open" (before answering a hall call and before the doors open) and the "word" is "slow, long, ..." (words uttered when the arrival of a car is felt to be slow or when the wait time is felt to be long, etc.), the corresponding "control" is "allocation change / weighting due to predicted non-response" (allocation change / weighting of cars by adjusting the time of predicted non-response).

[0040] In addition, if the "elevator operation state" is "responding to car call registered floor" (while the car is heading to the registered floor where the car call was registered) and the "word" is "crowded, ..." (words uttered when the car is crowded with many people), the corresponding "control" is "suppression of additional allocations in proportion to the car weighting" (suppressing additional allocations of the car to car call registered floors in proportion to the car weighting).

[0041] The "threshold" is a threshold for the frequency of occurrence of the corresponding "word" and is used to set a condition for implementing the corresponding "control" or a condition for canceling the implementation of the corresponding "control." Note that the frequency of occurrence may indicate the number of times the word appears within a certain period of time, or may indicate the ratio of the number of times the word appears to the number of all words appearing within a certain period of time.

[0042] The "thresholds" include a first threshold indicating the condition for implementing the corresponding "control" and a second threshold indicating the condition for canceling the implementation of the corresponding "control." When the frequency of occurrence of the "word" exceeds the first threshold, the corresponding "control" is implemented, and when the frequency of occurrence of the "word" falls below the second threshold, the implementation of the corresponding "control" is canceled. The second threshold may be a value lower than the first threshold, or may be the same value as the first threshold.

[0043] The above-mentioned "elevator operation status," "word," "control," and "threshold" each show the current setting contents in real time. In contrast, "results" show the change history of the setting contents of the above-mentioned "elevator operation status," "word," "control," and "threshold." Furthermore, "results" show the history of various words that have been detected so far and the time-based changes in the frequency of their occurrence, along with the various words that are currently detected and their occurrence frequency. Furthermore, "results" shows the history of whether or not control has been implemented so far, and the change history of the control, if any.

[0044] This makes it possible to check, for example, the correlation between the amount or rate of change in the frequency of appearance of a word before and after implementing "control." Also, if the content of "control" is changed, it is possible to check the correlation between the content of control before and after the change and the amount or rate of change in the frequency of appearance of a word. If the "threshold" is changed, it is also possible to check the correlation between the threshold before and after the change and the amount or rate of change in the frequency of appearance of a word.

[0045] Returning to the explanation of Fig. 1, the conversation classification unit 22d classifies each word extracted (detected) by the voice analysis unit 22b with reference to the information management unit 22c. For example, it determines whether or not each extracted word corresponds to any of the words expressing various dissatisfaction set in the association information explained in Fig. 4, and if there is any, it determines which word it corresponds to. The classification result is recorded in "achievement".

[0046] The occurrence frequency counting unit 22e counts the occurrence frequency of each word classified by the conversation classification unit 22d at regular time intervals. The counting results are recorded in the "performance" field.

[0047] The situation determination unit 22f determines whether the occurrence frequency of various words expressing dissatisfaction has increased or decreased beyond a threshold. Specifically, based on the counting result of the occurrence frequency counting unit 22e, the situation determination unit 22f determines whether there is a word whose occurrence frequency exceeds a first threshold, and whether the occurrence frequency of the word that exceeds the first threshold has fallen below a second threshold.

[0048] The operation control adjustment unit 22g adjusts the control applied to the elevator operation based on an increase or decrease in the words expressing the dissatisfaction of elevator users. Specifically, when the situation determination unit 22f determines that there is a word whose occurrence frequency exceeds a first threshold, the operation control adjustment unit 22g decides to implement a control associated with the word, and instructs the operation control unit 23 to implement the control. In addition, when the situation determination unit 22f determines that the occurrence frequency of the word that exceeds the first threshold has fallen below a second threshold, the operation control adjustment unit 22g decides to cancel the implementation of the control associated with the word, and instructs the operation control unit 23 to cancel the control.

[0049] If there are multiple words that exceed the first threshold, only one control may be implemented and the remaining controls may not be implemented (for example, if there is one control being implemented, implementation of other controls may not be permitted until that control is released), or multiple controls may be implemented if they can be implemented simultaneously without causing any problems. Depending on the combination of multiple controls, there may be cases where simultaneous implementation will not cause any problems and cases where it will cause problems.

[0050] When the occurrence frequency of a word that has increased does not decrease even after a certain period of time has passed, the resetting processing unit 22h changes the control being performed so that the occurrence frequency decreases. Specifically, when the occurrence frequency of a word that exceeds a first threshold does not fall below a second threshold for a certain period of time or more, the resetting processing unit 22h changes the control associated with the word.

[0051] When changing the control, the content of the "control" set in the association information described in FIG. 4 is changed. For example, if the occurrence frequency does not decrease even when the control "automatically dispatch another vehicle to the detected floor" corresponding to the word "cannot board, ..." is implemented, a change such as increasing the number of vehicles dispatched to the detected floor by one may be made. Also, more control candidates may be prepared for each word. In that case, for many controls, for example, AI (Artificial Intelligence) may be made to learn the correlation between the content of the control before and after the change and the amount or rate of change in the occurrence frequency of the word, and the optimal control for reducing the occurrence frequency of the word may be derived by the AI.

[0052] By configuring it as described above, user complaints can be automatically reflected in elevator operation at the appropriate time and without hassle, improving both the comfort and convenience of elevator users and the convenience of managers, etc.

[0053] <Modification> Next, various modifications of the above-described embodiment will be described.

[0054] Change example 1 The information management unit 22c may be configured to have a function of allowing an elevator user to change the contents of any "word" or "control" included in the association information from the information terminal 11. The information management unit 22c may be configured to allow the contents of the "elevator operation status" to be changed as well.

[0055] The changed contents may be selected from among options prepared in advance. Furthermore, new contents of "elevator operation state", "word" and "control" may be selected from among options prepared in advance and added to the association information.

[0056] In addition, when the elevator user is configured to change / add association information from the information terminal 11 as described above, a certain limit may be set on the operation of change / add to prevent inappropriate change / addition. Also, when an inappropriate operation is performed, the information terminal 10 of the manager or the like may be notified of the fact.

[0057] Change example 2 The information management unit 22c may be configured to have a function of setting a threshold value according to the priority assigned to each word or the priority assigned to each control as a first threshold value corresponding to each of various words in the association information.

[0058] The priority may be determined in advance for each word or for each control, or may be determined independently by the elevator user via the information terminal 11.

[0059] For example, the higher the priority of a word that indicates a strong discomfort to elevator users, the lower the first threshold value may be set so that control corresponding to that word is more likely to be implemented, and conversely, the lower the priority of a word that indicates a weak discomfort to elevator users, the higher the first threshold value may be set. In this case, it is desirable to set each first threshold value in a well-balanced manner according to the respective priorities. It is also desirable to adjust the second threshold value in accordance with the adjustment of the first threshold value.

[0060] Change example 3 The driving control adjustment unit 22g may be configured to have a function of changing the "threshold" or "control" associated with the word expressing dissatisfaction, or the frequency of occurrence of the word expressing dissatisfaction, when a word expressing satisfaction (positive emotion) that is the opposite to a word expressing dissatisfaction is detected.

[0061] When a word expressing satisfaction (positive emotion) that is the opposite of a word expressing dissatisfaction is detected, if a control corresponding to the word expressing dissatisfaction is being implemented, the second threshold may be increased by a predetermined value, or the currently implemented control may be weakened, so that the implementation of the control corresponding to the word expressing dissatisfaction is more likely to be released. Also, instead of increasing the second threshold by a predetermined value, a value obtained by subtracting the frequency of occurrence of a word expressing satisfaction (positive emotion) from the frequency of occurrence of the word expressing dissatisfaction may be used for comparison with the second threshold.

[0062] These processes can also be applied when control corresponding to words expressing dissatisfaction is not being implemented. In other words, when a word expressing satisfaction (positive emotion) that is the opposite of a word expressing dissatisfaction is detected, if control corresponding to the word expressing dissatisfaction is not being implemented, the first threshold may be increased by a predetermined value so that control corresponding to the word expressing dissatisfaction is less likely to be implemented, or instead of increasing the first threshold by a predetermined value, a value obtained by subtracting the frequency of occurrence of words expressing satisfaction (positive emotion) from the frequency of occurrence of the word expressing dissatisfaction may be used for comparison with the first threshold.

[0063] Change example 4 The information management unit 22c may be configured to have a function of allowing information indicating changes in control that reduce dissatisfaction among elevator users to be viewed from an external information terminal.

[0064] As described above, the association information managed by the information management unit 22c includes "elevator operation state", "word", "control", and "threshold", each of which indicates the current setting contents in real time. Also, as described above, "performance" not only indicates the change history of the setting contents of "elevator operation state", "word", "control", and "threshold", but also indicates the history of the time-based change of various words detected so far and their occurrence frequency together with various words detected so far and their occurrence frequency, and further indicates the history of whether or not control has been implemented so far, and the change history of the control if there has been a change.

[0065] This makes it possible to check, for example, the correlation between the amount or rate of change in the frequency of appearance of a word before and after implementing "control." Also, if the content of "control" is changed, it is possible to check the correlation between the content of control before and after the change and the amount or rate of change in the frequency of appearance of a word. If the "threshold" is changed, it is also possible to check the correlation between the threshold before and after the change and the amount or rate of change in the frequency of appearance of a word.

[0066] It is desirable to make such association information viewable in a display format that is easy for elevator users, managers, etc. to understand through information terminals. In that case, it is desirable to adopt a display format that is easy to understand visually, using not only characters and tables but also graphs, illustrations, etc., so that elevator users and managers, etc. can easily realize the effect of reducing elevator users' dissatisfaction.

[0067] Change example 5 The operation control adjustment unit 22g may be configured to have a function of applying control suited to the elevator user's preferences to the elevator operation.

[0068] Voiceprints and ID cards are used to identify individual elevator users. For example, buildings with security gates are often equipped with card readers that read information from ID cards (security cards, etc.). In such cases, individuals can be identified using the information on the ID card. Additionally, intercoms equipped with microphones are often installed near the entrances of apartment buildings, etc. In such cases, individuals can be identified using the voiceprints of the voice picked up from the microphone.

[0069] An example of the configuration when a card reader is used is shown in Fig. 5. When a card reader 19 is installed at a security gate of a building as shown in Fig. 5, the information on the ID card read by the card reader 19 is arranged to be transmitted to an operation control adjustment device 22 in a group management control device 20. On the side of the operation control adjustment device 22, an information management unit 22c identifies an individual from the information on the ID card, and manages information that associates a "user ID" (an identification number of an elevator user) with a "control preference" (the control preferred by that elevator user).

[0070] Figure 6 shows the concept of information that associates "user ID" with "control preference." For example, an elevator user with user ID "010001" is associated with "Control A" as a control preference. Also, an elevator user with user ID "010002" is associated with "Control B" as a control preference. For example, when the arrival of an elevator user with user ID "010001" is detected, "Control A" can be applied to the elevator operation.

[0071] In addition, the "preference control" may be determined by an AI based on, for example, voices expressing satisfaction or dissatisfaction that an elevator user has made in the past, or the elevator user may be able to use the information terminal 11 to select from among options prepared in advance.

[0072] Change example 6 The operation control adjustment device 22 may be provided outside the group management control device 20.

[0073] That is, the operation control adjustment device 22 does not necessarily have to be provided inside the group management control device 20 as shown in Fig. 1. The operation control adjustment device 22 may be provided independently at a location separate from the group management control device 20. In that case, all of the functions of the operation control adjustment device 22 may be provided at a location separate from the group management control device 20, or only some of the functions of the operation control adjustment device 22 may be provided at a location separate from the group management control device 20.

[0074] FIG. 7 shows an example of a configuration in which the operation control adjustment device 22 is provided independently of the group management control device 20. In FIG.

[0075] The operation control adjustment device 22 shown in FIG. 7 can communicate with the group management control device 20, and realizes the same functions and operations as the operation control adjustment device 22 in the group management control device 20 described above. That is, the operation control adjustment device 22 shown in FIG. 7 can acquire information stored in the call memory unit 21 described in FIG. 1, acquire voice signals supplied from the sound collection microphones 18a to 18c, acquire voice signals supplied from the sound collection microphones 16a to 16, transmit and receive information to and from the information terminals 10 and 11, and the operation control adjustment unit 22g can instruct the operation control unit 23 to carry out control. In this case, the operation control adjustment device 22 may be configured to directly acquire the voice signals supplied from the sound collection microphones 16a to 16 and the voice signals supplied from the sound collection microphones 18a to 18c without passing through the group management control device 20. The operation control adjustment device 22 may also be configured to directly transmit and receive information to and from the information terminals 10 and 11 without passing through the group management control device 20.

[0076] <Example of operation> Next, an example of the operation of the operation control adjustment device 22 will be described with reference to the flowchart of FIG.

[0077] First, the information management unit 22c performs a process of setting association information (step S1). Here, the contents of the various "elevator operation state", "word", "control", and "threshold value" described in FIG. 4 are set.

[0078] Next, the voice collection unit 22a distinguishes and collects the voices collected by the voice collection microphones 16a to 16c installed for each car at the boarding area on each floor, and also distinguishes and collects the voices collected by the voice collection microphones 18a to 18c for each car (step S2).

[0079] Next, the voice analysis unit 22b converts each piece of voice data collected by the voice collection unit 22a into text and performs morphological analysis or the like to extract (detect) each word (step S3).

[0080] Next, the conversation classification unit 22d classifies each word extracted (detected) by the voice analysis unit 22b (step S4). For example, it determines whether or not each extracted word corresponds to any of the words expressing various dissatisfaction set in the association information described in Fig. 4, and if there is any, it determines which word it corresponds to. The classification result is recorded in "achievement".

[0081] Next, the occurrence frequency counting unit 22e counts the occurrence frequency of each word classified by the conversation classification unit 22d at regular time intervals (step S5). The counting result is recorded in the "performance" field.

[0082] The situation determination unit 22f determines whether the occurrence frequency of various words expressing dissatisfaction has increased or decreased beyond a threshold (step S6). Specifically, based on the counting result of the occurrence frequency counting unit 22e, it determines whether there is a word whose occurrence frequency exceeds a first threshold, and whether the occurrence frequency of the word that exceeded the first threshold has fallen below a second threshold.

[0083] If there is no corresponding word (NO in step S6), the process repeats from step S2. For example, if the situation determination unit 22f determines that there is no word whose occurrence frequency exceeds the first threshold, or if it determines that the occurrence frequency of a word whose occurrence frequency exceeds the first threshold falls below the second threshold, the process returns to step S2. On the other hand, if there is a corresponding word (YES in step S6), the operation control adjustment unit 22g adjusts the control applied to the elevator operation (step S7).

[0084] For example, when the situation determination unit 22f determines that there is a word whose occurrence frequency exceeds a first threshold, the operation control adjustment unit 22g decides to implement a control associated with the word and instructs the operation control unit 23 to implement the control. When the operation control adjustment unit 22g determines that the occurrence frequency of the word exceeding the first threshold has fallen below a second threshold, the operation control adjustment unit 22g decides to cancel the implementation of the control associated with the word and instructs the operation control unit 23 to cancel the control.

[0085] If the occurrence frequency of a word that has increased does not decrease even after a certain period of time has passed, the resetting processing unit 22h changes the control being performed so that the occurrence frequency decreases (step S8). Specifically, if the occurrence frequency of a word that exceeds the first threshold does not fall below the second threshold for a certain period of time or more, the resetting processing unit 22h changes the control associated with the word. Then, the process returns to step S2. If resetting processing is not required, the process returns to step S2 without doing anything.

[0086] This allows user complaints to be automatically and hassle-freely reflected in elevator operation at the appropriate time, improving both comfort and convenience for elevator users, as well as convenience for managers and others.

[0087] As described above in detail, according to the embodiment, it is possible to reduce user dissatisfaction and the burden on administrators and the like. [Explanation of symbols]
