However, in order for users to use elevators comfortably, it is also required to reduce the stress that users feel. The stress felt by elevator users may occur in conjunction with dissatisfaction with elevator operation, such as late arrival of a car or late departure of a car. The technique described in Patent Document 1 has not been able to reduce such stress.

One aspect of the present invention aims to reduce the stress of elevator users that occurs due to dissatisfaction with elevator operation.

In order to solve the above problems, an elevator operation control device according to one aspect of the present invention is an elevator operation control device that controls the operation of an elevator car, and the elevator car is stopped. an information acquisition unit that acquires at least one of the stress values of users at a boarding station; and an operation control unit that controls the operation of the car in accordance with the stress value acquired by the information acquisition unit. ing.

According to the above configuration, the operation control unit performs operation control of the car in accordance with at least one of the stress value of the car and the stress value of the user at the landing where the car stops. Therefore, for example, the car can be operated in such a way that the stress value of the user is reduced, so that the stress of the elevator user that occurs due to dissatisfaction with the operation of the elevator can be reduced.

In the elevator operation control device according to another aspect of the present invention, the information acquisition unit may acquire the stress value from a mobile terminal owned by the user.

According to the above configuration, the operation of the car can be controlled in accordance with the stress value using the stress value acquired from the mobile terminal owned by the user. Therefore, the operation of the car can be controlled according to the stress value without providing the elevator operation control device with a new function for determining the stress value.

In the elevator operation control device according to another aspect of the present invention, the information acquisition unit may acquire the stress value from an image processing device that calculates the stress value based on an image taken of the user.

According to the above configuration, the operation of the car can be controlled in accordance with the stress value using the stress value obtained from the image processing device that calculates the stress value based on the image of the user. Therefore, even if the user does not have any device for measuring stress values, the operation of the car can be controlled according to stress values.

In the elevator operation control device according to another aspect of the present invention, the stress value may be a value calculated based on at least one of a biometric value and an activity value of the user.

According to the above configuration, the stress value is calculated based on at least one of the biometric value and the activity value of the user. Therefore, since the stress value is calculated based on a value that changes depending on the magnitude of stress, it is possible to determine the stress value according to the actual magnitude of stress. Thereby, the operation of the car can be controlled in accordance with the stress actually felt by the user.

In the elevator operation control device according to another aspect of the present invention, the operation control unit may generate a car stress representative value that is a representative value of stress values of at least one user in the car, and a car stress representative value that is a representative value of stress values of at least one user in the car, and The operation of the car may be controlled in accordance with at least one of the stress representative values of the hall, which are representative stress values of one user.

According to the above configuration, the operation of the car is performed according to at least one of the representative value of the stress value of at least one user in the car and the representative value of the stress value of at least one user at the landing. Control takes place. Thereby, it is possible to efficiently and accurately grasp at least one of the stress value state of the users in the car and the stress value state of the users in the hall.

In the elevator operation control device according to another aspect of the present invention, when the car is stopped at the landing and the door is open, the operation control unit determines that the stress of the car is higher than the representative value of the hall stress. If it is larger than the representative value, the door opening period may be extended.

According to the above configuration, when the car is stopped at the landing and the stress value of the passenger at the landing is greater than the stress value of the car user, the operation control unit closes the door. The operation of the car is controlled so as to extend the door opening period without departing. This makes it possible to perform door opening/closing control that reduces stress on the user.

In the elevator operation control device according to another aspect of the present invention, when call registration is performed at a plurality of landings, the operation control unit controls the operation of the car toward each of the landings where the call registration has been performed. Create a plurality of sequences, and calculate, for each operation sequence, a predicted representative platform stress value after the completion of the operation for the users of each platform where the call registration has been performed, based on the stress value information acquired by the information acquisition unit. However, the operation of the cars may be controlled in an operation order in which the predicted hall stress representative value is minimized.

According to the above configuration, the operation control is performed to stop the car at the landing where the call registration has been performed so that the predicted landing stress value after the completion of the operation of the users of each landing where the call registration has been performed is minimized. It can be carried out. Therefore, the cars can be operated so that the stress value at each landing is as small as possible, which can alleviate user dissatisfaction.

In the elevator operation control device according to another aspect of the present invention, when there is a plurality of the cars headed to the hall for which call registration has been performed, the operation control unit controls the elevator car to The car may be stopped at the landing where the call registration has been performed.

According to the above configuration, among the plurality of cars, the car with the minimum stress value within the car can be stopped at the hall for which the call has been registered. Therefore, the car can be operated in such a way that the stress value of the users in the car is as small as possible, so that the dissatisfaction of the users can be alleviated.

In the elevator operation control device according to another aspect of the present invention, the operation control unit may be configured to determine whether the elevator car of the car heading toward the hall is higher than the representative value of the hall stress of the hall where the call registration has been performed. If the stress representative value is larger, the car may be allowed to pass through the hall where the call registration was performed.

According to the above configuration, based on the stress values of the car and the landing area where the call registration has been performed, it is determined whether the car should be stopped at the landing area where the call registration has been performed or whether the car should be allowed to pass through the landing area. It can be performed. Therefore, the car can be operated in such a way that the stress value of the car and the landing area where the call registration has been performed is as small as possible, so that user dissatisfaction can be alleviated.

In the elevator operation control device according to another aspect of the present invention, the information acquisition unit acquires attributes of users at the car or the landing, and the operation control unit acquires the attributes of the users at the car or the landing. A corrected stress value may be calculated based on the stress value and the attribute, and operation control of the car may be performed according to the corrected stress value.

According to the above configuration, for example, by calculating the corrected stress value such that the stress value becomes larger for a user who has an attribute that should be given priority, such as a wheelchair, the user who has the above-mentioned attribute can be given priority. It is possible to control the operation of the car.

A control method for an elevator operation control device according to one aspect of the present invention is a control method for an elevator operation control device that controls the operation of an elevator car, and the method includes controlling the elevator car and a landing area where the car stops. The method includes an information acquisition step of acquiring at least one of the user's stress values, and an operation control step of controlling the operation of the car in accordance with the stress value acquired in the information acquisition step.

[Embodiment 1]
<Overview of elevator operation control system>
Hereinafter, one embodiment of the present invention will be described in detail. FIG. 1 is a diagram showing an example of a functional block diagram of an elevator operation control system 100 according to Embodiment 1 of the present invention. The elevator operation control system 100 is a system that operates elevators in a manner that minimizes stress on elevator users caused by dissatisfaction with elevator operation.

As shown in FIG. 1, the elevator operation control system 100 includes an elevator operation control device 10, a landing 60, a car 20, a control panel 22, communication devices 30 and 50, and a stress value measuring device 40. We are prepared.

In FIG. 1, a car 20X and a car 20Y are shown as the car 20, and a landing 60A and a landing 60B are shown as the landing 60 where the car 20 stops, but the present invention is not limited to the above. There may be one car 20, or two or more cars. Further, the number of landings 60 may be two or more.

<Stress value measuring device>
The stress value measurement device 40 measures the stress value of the car 20 and the stress value of the user at the landing 60 where the car 20 stops.

Stress value information including the measured stress value is transmitted from the stress value measurement device 40 to the information acquisition unit 111, which will be described later, via the communication device 30 or the communication device 50. The stress value information includes information for identifying the user, user attribute information, stress value history, and the like. The user attribute information includes, for example, physically disabled person, elderly person, pregnant woman, stroller, VIP (Very Important Person), and the like. The information for identifying the user and the user's attribute information may be registered in the stress value measuring device 40 by the user in advance. Further, the stress value information may be directly transmitted to the information acquisition unit 111 by, for example, Internet communication using a carrier line, without going through the communication device 30 or the communication device 50 or the like.

In addition, the stress value measuring device 40 transmits the measured values themselves (for example, heart rate variability values, etc.) measured by the stress value measuring device 40 to the information acquisition unit 111, which will be described later, via the communication device 30 and the communication device 50. Good too.

The stress value measurement device 40 measures the user's stress value, for example, at every predetermined period. The predetermined period may be, for example, three minutes. Further, the stress value measured by the stress value measuring device 40 is accumulated in the stress value measuring device 40, for example.

The stress value that the stress value measuring device 40 transmits to the information acquisition unit 111 may be, for example, an average value, a maximum value, or a fluctuating value for an arbitrary period. Further, the stress value measurement device 40 may transmit the latest stress value to the information acquisition unit 111.

The method for measuring stress values is not particularly limited, and various methods can be used. Measurement methods include, for example, measuring the stress value using a mobile terminal owned by the user, measuring the stress value using an image of the user, and the like. An example of a stress value measurement method will be described below.

(An example of stress value measurement using a mobile device)
FIG. 1 shows a case where a mobile terminal 41 is used as the stress value measuring device 40. In this way, the stress value may be measured using the mobile terminal 41 owned by the user as the stress value measuring device 40.

Specifically, for example, a mobile terminal 41A is used as the stress value measuring device 40 in the hall 60A, and a mobile terminal 41B is used as the stress value measuring device 40 in the hall 60B. Furthermore, a mobile terminal 41X is used as the stress value measuring device 40 in the car 20X, and a mobile terminal 41Y is used as the stress value measuring device 40 in the car 20Y. Note that if each landing 60 and each car 20 have a plurality of users, the number of mobile terminals 41 will be equal to the number of users of each landing 60 and each car 20. For example, if there are three users at the landing 60A, there will be a total of three mobile terminals 41 at the landing 60A.

When measuring a stress value using a mobile terminal 41 as the stress value measuring device 40, a smart watch may be used as the mobile terminal 41, for example. In that case, the smart watch may measure the heart rate variability value, which indicates the change in the length of each beat of the user's heart, and the smart watch may calculate the stress value based on the measured heart rate variability. . In addition to heartbeat, the smartwatch may measure blood flow, SpO2 value, blood pressure, body temperature, amount of perspiration, etc., and calculate the stress value based on at least one of these. In this way, by using the smart watch worn by the user, it is possible to obtain the user's stress value without introducing a device with a new function for determining the stress value.

Each mobile terminal 41 transmits the measured stress value to the communication device 30 installed at each landing 60 or each communication device 50 installed at each car 20.

Specifically, for example, in the hall 60A, the stress value measured by the mobile terminal 41A is transmitted to the communication device 30A installed in the hall 60A. At the landing 60B, the stress value measured by the mobile terminal 41B is transmitted to the communication device 30B installed at the landing 60B. The car 20X transmits the stress value measured by the mobile terminal 41X to the communication device 50X installed in the car 20X. The car 20Y transmits the stress value measured by the mobile terminal 41Y to the communication device 50Y installed in the car 20Y.

Note that when a smart watch is used as the mobile terminal 41, the smart watch may transmit the stress value to the communication device 30/50 via the smartphone.

(Other examples of stress value measurement using a mobile device)
The stress value is not limited to one calculated based on the heartbeat, but may be a value calculated based on at least one of the user's biometric values and activity values. Here, the biometric value is a value that changes as the body moves internally, and the activity value is a value that changes as the body itself moves.

In this case, for example, a mobile terminal 41 is used as the stress value measuring device 40 as shown in FIG. Specifically, a smartphone is used as the mobile terminal 41, and biometric values such as heart rate, blood pressure, and body temperature are obtained from the log of the smartphone, and activity values such as the smartphone's "acceleration," "app usage history," and "user's The smartphone may calculate the stress value by acquiring information such as "recognition result information of the activity state."

(Measurement of stress value using images)
FIG. 2 is a diagram showing another example of the functional block diagram of the elevator operation control system 100 according to the first embodiment of the present invention, and shows a case where an image processing device 42 is used as the stress value measuring device 40. In this way, the image processing device 42 may be used as the stress value measurement device 40, and the stress value may be calculated based on an image of the user.

When using the image processing device 42 as the stress value measuring device 40, the image processing device 42 and the camera 43 are installed at each landing 60 and each car 20. The camera 43 photographs the face of the user at each installed hall 60 or each car 20, and transmits the photographed image to the image processing device 42.

Specifically, for example, an image processing device 42A is used as the stress value measuring device 40 in the landing hall 60A, and a camera 43A is installed in the landing hall 60A. At the landing 60B, an image processing device 42B is used as the stress value measuring device 40, and a camera 43B is installed at the landing 60B. In the car 20X, an image processing device 42X is used as the stress value measuring device 40, and a camera 43X is installed inside the car 20X. In the car 20Y, an image processing device 42Y is used as the stress value measuring device 40, and a camera 43Y is installed inside the car 20Y.

Note that when using the image processing device 42 as the stress value measurement device 40, even if there are multiple users at each landing 60 and each car 20, it is not necessary to install an additional image processing device 42 and camera 43 for each number of users. It is sufficient to have at least one installed. Further, the image processing device 42 may not be installed in each hall 60 and each car 20, and the elevator operation control device 10 may have the function of the image processing device 42.

The image processing device 42 can, for example, analyze images captured by the camera 43 to detect changes in the user's skin color, recognize the state of the autonomic nervous system from the pulse interval recognized thereby, and calculate the stress value. It is possible. This makes it possible to obtain the user's stress value even if the user does not have any device for measuring stress values.

Alternatively, the user's face may be photographed with a mobile terminal 41 that the user owns, the photographed image may be transmitted to the image processing device 42, and the stress value may be calculated by the image processing device 42.

<Communication device>
The communication device 30 is arranged at each landing 60 and transmits the stress value transmitted from the stress value measuring device 40 at each landing 60 to the information acquisition unit 111. As a result, the stress value received by the information acquisition unit 111 is given information as to which hall 60 the communication device 30 was passed through, so the stress value received by the information acquisition unit 111 is attached to the hall where the user who measured the stress value is located. 60 can be specified.

The communication device 50 is arranged in each car 20 and transmits the stress value transmitted from the stress value measurement device 40 to the information acquisition unit 111. As a result, the stress value received by the information acquisition unit 111 is given information as to which communication device 50 of the car 20 it was passed through, so the stress value received by the information acquisition unit 111 is attached to the user who measured the stress value. It is possible to specify the car 20 in which the person is present. Note that the communication device 50 may transmit the stress value transmitted from the stress value measurement device 40 to the information acquisition unit 111 via the control panel 22.

The communication method of communication device 30 and communication device 50 is not particularly limited. For example, communication between the stress value measuring device 40, the communication device 30, and the communication device 50 may be performed by wireless communication such as Bluetooth (registered trademark). Further, for example, communication between the communication devices 30 and 50 and the elevator operation control device 10 including the information acquisition unit 111 may be performed by wired communication or wireless communication.

Furthermore, the stress values of users of the hall 60 do not need to be transmitted via the communication device 30. For example, when transmitting a measured stress value while registering a call using a call registration application, the stress value may be directly transmitted from the mobile terminal 41 to the information acquisition unit 111 via a carrier line. Since the current floor is also registered when registering a call using the call registration application, the stress value may be transmitted along with information about the current floor of the user whose stress value was measured during call registration using the call registration application.

<Car and control panel>
In the elevator operation control system 100, the car 20 is, for example, a case that carries users up and down inside the tower.

The control panel 22 is provided in each car 20, communicates with the elevator operation control device 10, and controls the operation of the entire elevator including the car 20. For example, the car 20X is provided with a control panel 22X, and the car 20Y is provided with a control panel 22Y. Each control panel 22 includes a control section 23 and a memory 24. The memory 24 stores various programs executed by the control panel 22 and data used by the programs.

The control unit 23 centrally controls each part of the elevator including the car 20. The functions of the control unit 23 may be realized by the CPU executing a program stored in the memory 24. Specifically, the control unit 23 controls door opening/closing operations of the car 20 in accordance with operation control based on instructions from the elevator operation control device 10.

Further, the control unit 23 transmits car operation information including current location information of the car 20, door opening/closing information, moving direction, etc. to the elevator operation control device 10.

<Elevator operation control device>
The elevator operation control device 10 performs operation control of an elevator car 20. The elevator operation control device 10 includes a control section 11 and a memory 12.

The control unit 11 centrally controls each unit of the elevator operation control device 10. The functions of the control unit 11 may be realized by the CPU executing a program stored in the memory 12. Details of the control unit 11 will be described later. The memory 12 stores various programs executed by the control unit 11 and data used by the programs. The control unit 11 includes an information acquisition unit 111 and an operation control unit 112.

In addition, when a plurality of cars 20 exist, the functions of the elevator operation control device 10 may be realized by a group management control panel.

(Information acquisition department)
The information acquisition unit 111 acquires at least one of the stress values of the car 20 and the stress value of the user at the hall 60 where the car 20 stops. The information acquisition unit 111 acquires the stress values of the users in the car 20 and the landing 60 by acquiring stress value information from the communication device 30 and the communication device 50 every arbitrary period or at a predetermined timing, for example. Good too.

For example, when there are multiple users in the car 20 or the landing 60, the information acquisition unit 111 acquires stress value information for each user.

Note that the information acquisition unit 111 may acquire stress value information of users only at a designated landing 60. For example, since it is assumed that there are many users at the landing 60 near the entrance, the administrator of the elevator operation control system 100 specifies in advance a landing 60 other than the landing 60 near the entrance as the landing 60 from which stress value information is to be acquired. However, the information acquisition unit 111 may acquire the stress value information of the user only at the designated landing 60.

In that case, for example, if there are only two landings 60, one near the entrance and one on another floor, the number of landings 60 from which the information acquisition unit 111 acquires stress value information is one. Further, as described above, if stress value information is not acquired for the landing 60 near the entrance, it is not necessary to install equipment such as the communication device 30 necessary for acquiring stress value information in the landing 60.

The information acquisition unit 111 may acquire stress values from various stress value measuring devices 40 via the communication devices 30 and 50. For example, the information acquisition unit 111 acquires stress values from the mobile terminal 41 functioning as the stress value measuring device 40 from the landing 60, and acquires stress values from the image processing device 42 functioning as the stress value measuring device 40 from the car 20. You can also get the value. In that case, each stress value acquired by the information acquisition unit 111 is converted into a stress value of the same standard and used in the operation control unit 112, for example. This can reduce the number of users who cannot obtain stress values. Note that a specific conversion method will be described later.

The information acquisition unit 111 also acquires car operation information and call registration information. The call registration information is information that is registered by the user and includes the boarding floor and the exit floor at which the car 20 is desired to be stopped.

In this embodiment, for example, when the car 20X is stopped at the landing 60A, the information acquisition unit 111 acquires the stress value of the user in the car 20X and the stress value of the user at the landing 60A. The information acquisition unit 111 outputs the acquired stress value to the operation control unit 112.

(Operation control section)
The operation control unit 112 controls the operation of the car 20 according to the stress value acquired by the information acquisition unit 111. Specifically, the operation control unit 112 generates a car stress representative value that is a representative value of stress values of users in the car 20 and a hall stress representative value that is a representative value of stress values of users in the landing 60. Calculate the value. The operation control unit 112 controls the operation of the car 20 according to the car stress representative value and the hall stress representative value.

Here, the representative stress value may be, for example, the total value, maximum value, average value, or median value of a plurality of stress values. Furthermore, if there are users who cannot obtain stress values because they do not have the mobile terminal 41, for example, the average value of the stress values of the users who have obtained stress values may be used as the representative value.

That is, the operation control unit 112 determines a car stress representative value that is a representative value of the stress value of at least one user in the car 20 and a representative value of the stress value of at least one user in the landing 60. The operation of the car 20 may be controlled according to at least one of the hall stress representative values.

By calculating the car stress representative value and the landing hall stress representative value, the stress value state of the users in the car 20 and the stress value state of the users in the landing hall 60 can be efficiently and accurately grasped. be able to. Further, for example, since the car 20 can be operated in such a way that the stress value of the user is reduced, it is possible to reduce the stress of the elevator user that occurs due to dissatisfaction with the operation of the elevator.

Furthermore, when stress values are acquired by the information acquisition unit 111 from various stress value measurement devices 40, the operation control unit 112 may calculate stress representative values by converting them into stress values based on the same standard, for example. . The operation control unit 112 may calculate the stress representative value using, for example, a table that converts stress values obtained from various stress value measuring devices 40 into stress values of the same standard.

Further, when the information acquisition unit 111 acquires the measurement value itself (for example, heart rate variability value, etc.) measured by the stress value measurement device 40 from the stress value measurement device 40, the operation control unit 112, for example, It may be converted to a stress value of the same standard.

In the present embodiment, the operation control unit 112 controls the car 20X when the car 20X is stopped at the landing 60A and the door is open, and the car stress representative value of the car 20A is higher than the car stress representative value of the car 20X. If it is larger than , the door opening period will be extended. This makes it possible to perform door opening/closing control that reduces stress on the user. Here, the case where the car 20X is stopped at the landing 60A and the door is open refers to the state where the door of the car 20X is stopped at the landing 60A, and the door is fully opened and the door is closed. It also includes the operating state.

In addition, if there is a user whose stress value cannot be obtained because the user does not have a mobile terminal 41, etc., the operation control unit 112 calculates the average value of the stress values of the users who have obtained the stress value. It may also be used as a stress value for users.

Furthermore, if the stress value cannot be obtained from a single user in either the car 20 or the landing area 60, the operation control unit 112 determines whether the stress value of the car 20 or the boarding area 60 exceeds the threshold value. Operation control may also be performed. For example, if a stress value cannot be obtained from even one user in the car 20, the operation control unit 112 may extend the door opening period when the representative stress value of the landing 60 exceeds a threshold value. .

Furthermore, the operation control unit 112 may calculate a corrected stress value based on the stress value acquired by the information acquisition unit 111 and the attributes of the user, and may control the operation of the car 20 according to the corrected stress value. For example, the operation control unit 112 calculates a corrected stress value by multiplying the acquired stress value by a predetermined weighting coefficient according to the user's attribute information, and calculates the car stress representative value and the car stress value according to the corrected stress value. The representative value of the hall stress may be calculated and the operation of the car 20 may be controlled. Thereby, the operation of the car 20 can be controlled to give priority to users who have the attributes.

<Example of operation of elevator operation control system>
A control method of the elevator operation control device 10 that controls the operation of the elevator car 20 includes information that acquires at least one of the stress values of the car 20 and the stress value of the user at the landing 60 where the car 20 stops. The process includes an acquisition step and an operation control step of controlling the operation of the car 20 according to the stress value acquired in the information acquisition step.

FIG. 3 is a flow diagram showing an example of the operation of the elevator operation control system 100 according to the first embodiment of the present application. An example of the operation of the elevator operation control system 100 according to Embodiment 1 of the present application will be described based on FIG. 3. An example of the operation of the elevator operation control system 100 when the car 20X stops at the landing 60A will be described below.

As shown in FIG. 3, when the car 20X stops at the landing 60A and the door opening is completed (YES in step S1), the information acquisition unit 111 acquires stress value information of the users of the landing 60A and the car 20X. The operation control unit 112 calculates a hall stress representative value and a car stress representative value (step S3).

The operation control unit 112 determines whether it is time for the car 20X to close its door (step S4). If it is time for the car 20X to close its door (YES in step S4), the operation control unit 112 compares the representative value of the hall stress with the representative value of the car stress, and determines that the representative value of the hall stress is higher than the representative value of the car stress. It is determined whether the value is larger than the representative value (step S5). If the car stress representative value is larger than the hall stress representative value (NO in step S5), the operation control unit 112 closes the door of the car 20X and causes the car to depart from the hall 60A (step S6, operation control unit step ).

On the other hand, if the hall stress representative value is larger than the car stress representative value (YES in step S5), the operation control unit 112 extends the door open time of the car 20X (step S7), and performs the operation in step S4. Return to

Note that if the car 20X has stopped at the landing 60A and the door opening has not been completed (NO in step S1), the process waits until the door opening is completed.

Furthermore, when it is time for the door of the car 20X to close (YES in step S4), the determination in step S5 may be made with the door open or may be made during the door closing operation. In the case where the determination in step S5 is made during the door closing operation, if it is determined in step S5 that the hall stress representative value is larger than the car stress representative value, the operation control unit 112 closes the door of the car 20X. Switch the closing action to the door opening action.

Further, even if the door opening of the car 20X is extended in step S7, for example, if any of the following (I) to (III) is satisfied, the operation control unit 112 closes the door of the car 20X. You may depart from the landing 60A. (I) If the extension time of the door opening time is longer than the specified time, (II) If the door opening time is extended more than the specified number of times, (III) (I) and (II) are satisfied and the landing 60A When the difference in stress representative value with car 20X becomes less than a predetermined value.

If the stress value at landing 60A does not decrease even after extending the door opening, the representative landing stress value will continue to be larger than the representative car stress value, and car 20X may not be able to depart from landing 60A. There is sex.

On the other hand, if any of the above (I) to (III) is satisfied, by closing the door of the car 20X and departing from the landing 60A, the representative value of the car stress will be higher than the representative value of the car stress. Even if the car is large, the car 20X can be closed and departed from the landing 60A. For example, if the door opening time of the car 20X at the landing 60A is extended by a predetermined number of times or more, the car 20X can be closed and the car 20X departs from the landing 60A.

Unlike the first embodiment, the other configurations are the same as the first embodiment.

When call registration is performed at a landing 60 and there is a car 20 headed for the landing 60, the information acquisition unit 111 acquires stress value information of the user of the landing 60 and stress value information of the user of the car 20. get. Furthermore, stress value information may not be acquired even for the car 20 heading toward the landing 60 for which call registration has been performed if the degree of congestion is greater than or equal to a predetermined value.

The operation control unit 112 determines whether there is a car 20 without a user boarding, which is capable of heading to the registered landing area 60 and exists within a predetermined distance from the landing area 60. Here, the car 20 that can go to the registered landing 60 is, for example, a car 20 that is not allocated to another landing 60 and is stopped, or a car 20 that is not allocated to another landing 60. However, the car 20 is heading towards the landing 60 for which the call has been registered (it is scheduled to pass through the landing 60 for which the call has been registered).

If there is a car 20 without a user boarding that is capable of heading to the registered landing 60 and exists within a predetermined distance from the landing 60, the car 20 is stopped at the landing 60; Other cars 20 are allowed to pass through the landing 60.

The operation control unit 112 selects the car 20 closest to the hall 60 for which the call has been registered, from among the cars 20 heading for the hall 60 for which the call has been registered.

The operation control unit 112 determines whether or not the congestion degree of the nearest car 20 among the cars 20 headed for the registered hall 60 is less than or equal to a predetermined value. When the degree of congestion of the car 20 is greater than a predetermined value, the operation control unit 112 allows the car 20 to pass through the hall 60 for which the call has been registered, and allows the car 20 to pass through the hall 60 for which the call has been registered. Among them, the 20 closest cars are selected.

If the representative car stress value of the car 20 heading towards the hall 60 is greater than the representative stress value of the hall 60 for which the call registration has been performed, the operation control unit 112 calls the car 20. The user is allowed to pass through the boarding hall 60 where the registration was performed. Thereby, the car 20 can be operated so that the stress values of the car 20 and the landing hall 60 where the call registration has been performed are as small as possible, so that the dissatisfaction of the users can be alleviated.

Specifically, when the car 20X heads to the registered landing 60A, and the representative car stress value of the car 20X is larger than the representative value of the car stress of the landing 60A, the operation control is performed. The section 112 allows the car 20X to pass through the landing 60A. Further, when the representative car stress value of the car hall 60A is larger than the representative car stress value of the car 20X, the operation control unit 112 stops the car 20X at the hall 60A.

Further, if the stress value cannot be obtained from a single user in either the car 20X or the landing 60A, the operation control unit 112 determines whether the stress value of the other car 20X exceeds the threshold or not. Operation control may also be performed. For example, if a stress value cannot be obtained from even one user in the car 20X, the operation control unit 112 stops the car 20X at the landing 60A when the representative stress value of the landing 60A exceeds a threshold value. Alternatively, the car 20X may be allowed to pass through the landing 60A when the representative stress stress value of the landing 60A is less than or equal to a threshold value.

Further, if there is a car 20 without a user, even if the car 20 is not the closest car 20 to the landing 60A, the car 20 is stopped at the landing 60A without acquiring the stress value, Other cars 20 may be allowed to pass through the landing 60A.

If there is no passenger car 20 without a user (NO in step S32), the operation control unit 112 selects the car closest to the landing 60 among the cars 20X and 20Y headed for the registered landing 60A. 20, car 20X, is selected (step S33).

Next, the operation control unit 112 determines whether the degree of congestion of the car 20X is less than or equal to a predetermined value (step S34). When the degree of congestion of the car 20X is less than or equal to the predetermined value (YES in step S34), the information acquisition unit 111 acquires stress value information of the hall 60A and the car 20X (step S35).

Next, the operation control unit 112 calculates the representative value of the car stress of the user of the car 60A and the representative value of the car stress of the user of the car 20X (step S36), and determines that the representative value of the car stress is higher than the representative value of the car stress of the user of the car 20X. It is determined whether the value is larger than the representative value (step S37).

If the representative car stress value of the user of the car 20X is greater than the representative value of the stress of the car 20X for the user of the landing 60A (YES in step S37), the operation control unit 112 moves the car 20X to the landing 60A. Let it pass. Furthermore, the operation control unit 112 selects the nearest car 20, that is, the car 20Y, from among the other cars 20 headed for the registered landing hall 60A (step S38), and performs the process of step S34. .

If the representative car stress value of the user of the car 20X is smaller than the representative value of the car stress of the user of the boarding hall 60A (NO in step S37), the operation control unit 112 moves the car 20X to the boarding hall 60A. It is stopped (step S39).

In step S32, if there is a car 20 without a user boarding within a predetermined distance from the landing 60A (YES in step S32), the operation control unit 112 stops the car 20 at the landing 60A ( Step S39).

In step S34, if the degree of congestion of the car 20X is greater than the predetermined value (NO in step S34), the process of step S38 is performed.

Furthermore, if the call has not been registered (NO in step S31), the process waits until the call is registered.
