[First Embodiment]
FIG. 1 is a block diagram illustrating a configuration example of an elevator air conditioning control system according to the first embodiment. As shown in FIG. 1, the elevator air conditioning control system includes an elevator car 20 that is subject to air conditioning control (hereinafter referred to as “target elevator”), a portable terminal 30 that is owned by an unspecified number of people, The elevator air conditioning control device 10 includes a car 20 and a portable terminal 30 that are communicably connected to the elevator air conditioning control device 10 via a communication line 40.

  The car 20 of the target elevator is provided with a temperature sensor 21 that measures the temperature in the car 20 and an air conditioner 22 that adjusts the temperature in the car 20. The air conditioner 22 receives the temperature (measured temperature) in the car 20 measured by the temperature sensor 21 and is controlled by the internal control unit 23 so that the difference between the measured temperature and the set temperature is small. . The operation of the air conditioner 22 controlled by the control unit 23 is, for example, the rotational speed of a compressor that discharges refrigerant, the rotational speed of a blower fan, or the like.

  In addition, the car 20 is provided with a communication unit 24 for communicating with the elevator air-conditioning control apparatus 10 via the communication line 40. The air conditioner 22 provided in the car 20 is connected to the communication unit 24, and the set temperature of the air conditioner 22 is updated according to the set temperature update command transmitted from the elevator air conditioning control device 10. The communication unit 24 receives the set temperature update command transmitted from the elevator air-conditioning control device 10 and passes it to the air-conditioning device 22, and also uses the current set temperature of the air-conditioning device 22 and the temperature measured by the temperature sensor 21 for the elevator It also has a function of transmitting to the air conditioning control device 10.

  In addition, the car 20 is provided with a microphone 25 that records (inputs) an utterance by a person (elevator user) in the car 20. The microphone 25 is connected to the communication unit 24. The communication unit 24 also has a function of transmitting an utterance by an elevator user input from the microphone 25 to the elevator air conditioning control device 10 as a voice message.

  In the present embodiment, since an example in which the elevator air-conditioning control device 10 is realized as one function of the elevator remote monitoring device, a large number of elevators monitored by the elevator remote monitoring device may be the target of air-conditioning control. it can. Therefore, in practice, a large number of cars 20 are connected to the elevator air conditioning control device 10 via the communication line 40. However, the functions of the respective cars 20 are the same, and the air conditioning control by the elevator air conditioning control device 10 is the elevator. In FIG. 1, only one car 20 is illustrated.

  The portable terminal 30 includes at least a message input unit 31 for a person who owns the portable terminal 30 to input a message by voice input or text writing, and a position of the portable terminal 30 (that is, a person who owns the portable terminal 30). A position detection unit 32 for detecting the position of the elevator) and a communication unit 33 for communicating with the elevator air-conditioning control apparatus 10 via the communication line 40. The portable terminal 30 may be any device having at least these functions, and may be a general-purpose portable device such as a smartphone, or may be a portable device dedicated to the elevator air conditioning control system of the present embodiment. Good.

  The message input unit 31 includes, for example, a microphone for inputting a voice message, a touch panel for inputting a text message, and the like. The message input using the message input unit 31 may be performed, for example, by accessing a dedicated site provided by the elevator air conditioning control system according to the present embodiment, or a publicly available SNS (Social Networking System). You may go to the site provided by. A voice or text message input using the message input unit 31 is sent directly from the communication unit 33 to the elevator air-conditioning control device 10 or indirectly via an SNS server or the like.

  The position detection unit 32 includes, for example, a GPS receiver, an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, and the like. When the person who has the portable terminal 30 is outdoors, the position of the portable terminal 30 can be detected based on, for example, a GPS signal received by the GPS receiver. On the other hand, when the person holding the portable terminal 30 is indoors, the portable terminal 30 can be carried by a method such as pedestrian autonomous navigation (PDR: Pedestrian Dead Reckoning) using sensor signals of an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor. The position of the terminal 30 can be detected. The position information indicating the position of the mobile terminal 30 detected by the position detection unit 32 is directly from the communication unit 33 to the elevator air conditioning control device 10 together with the message input using the message input unit 31 or It is sent indirectly via an SNS server or the like.

  As described above, the portable terminal 30 is owned by an unspecified number of people. For this reason, a large number of portable terminals 30 are actually connected to the elevator air conditioning control device 10 via the communication line 40. However, since the functions of the portable terminals 30 are common, in FIG. Only the terminal 30 is illustrated. In the present embodiment, the elevator air-conditioning control device 10 only needs to be configured to be able to acquire a message input using the message input unit 31 of the mobile terminal 30 together with the position information, and the method for realizing the configuration is described above. It is not limited to the example.

  The elevator air-conditioning control device 10 acquires and analyzes the above-described voice and text messages, and reflects the feeling that the person actually feels about the temperature, and reflects the air-conditioning equipment 22 provided in the target elevator car 20. The air conditioner 22 is controlled by updating the set temperature. Since the air conditioning control by the elevator air conditioning control device 10 is performed independently for each elevator as described above, the following description will be made assuming air conditioning control for one elevator. In the case where a plurality of elevators are subject to air conditioning control, air conditioning control described below is performed for each elevator.

  The elevator air-conditioning control device 10 includes, for example, a computer system that executes various programs, a storage device such as an HDD (hard disk drive) that stores various information, and the elevator car 20 and the portable terminal 30 via the communication line 40. A communication interface for communication is provided as basic hardware. The elevator air conditioning control device 10 executes a predetermined control program on a computer system, for example, as shown in FIG. 1, for example, a communication unit 11, a message acquisition unit 12, a keyword extraction unit 13, an adjustment value calculation. Functional components such as the unit 14 and the set temperature update unit 15 are realized.

  The communication unit 11 communicates with the car 20 of the target elevator and the portable terminal 30 possessed by an unspecified number of people using the communication interface. For example, the communication unit 11 receives a voice message input from the microphone 25 in the car 20 or receives a voice or text message input from the message input unit 31 of the mobile terminal 30. Further, the communication unit 11 receives the current set temperature of the air conditioner 22 and the measured temperature of the temperature sensor 21 from the target elevator car 20, and targets the set temperature update command generated by the set temperature update unit 15 described later. Or sent to the elevator car 20.

  The message acquisition unit 12 acquires a voice or text message input within a predetermined area determined based on the position of the target elevator. The position of the target elevator can be specified by referring to the property database 16 prepared in advance, for example. The property database 16 is a database that stores information such as the installation position of the target elevator, the position of the building where the target elevator is installed, and the use of the building, and is created in advance and stored in a storage device such as an HDD. And As the predetermined area, for example, an area in a building site where the target elevator is installed, or an area within a predetermined distance from the installation position of the target elevator can be set.

  The message acquisition unit 12 determines the position indicated by the position information transmitted with the message based on the position of the target elevator for a voice or text message input using the message input unit 31 of the mobile terminal 30. If it is within the predetermined area, the message is acquired. In addition, for a message by voice input from the microphone 25 in the car 20 of the target elevator, the message is acquired because the position of the microphone 25 in the car 20 is within a predetermined area.

  The keyword extraction unit 13 extracts a predetermined keyword representing an impression on the temperature from the message acquired by the message acquisition unit 12. When the message acquired by the message acquisition unit 12 is a voice message, the voice message is first converted into text by voice recognition processing. For example, the keyword extraction unit 13 divides a message by text or a message converted from speech into text into words by morphological analysis, and collates each divided word with a keyword list 17 prepared in advance, thereby generating a message. Extract keywords from.

  In the keyword list 17 used for keyword extraction, words representing impressions on temperature are registered as keywords. For example, “hot”, “steaming”, “mushimushi”, “jirigiri” and the like indicating that the temperature is felt hot are registered in the keyword list 17. In addition, “cold”, “cool”, “freeze”, “zokuzoku”, and the like indicating that the temperature is felt cold are registered in the keyword list 17.

  In addition, in the keyword list 17, it is desirable that not only a keyword indicating the impression about the temperature but also a modifier indicating the degree of the impression about the temperature is registered. Examples of such modifiers include “very”, “very”, which indicates a high degree of impression of temperature, “little”, “a little”, etc., which indicates a low degree of impression of temperature. . In this case, if such a modifier is included in the message acquired by the message acquisition unit 12, the keyword extraction unit 13 extracts the modifier from the message together with the keyword. It is assumed that the keyword list 17 is created in advance and stored in a storage device such as an HDD.

  The adjustment value calculation unit 14 calculates an adjustment value for the set temperature of the air conditioner 22 of the target elevator based on the keyword extracted from the message by the keyword extraction unit 13. Here, an example of an adjustment value calculation method by the adjustment value calculation unit 14 will be described. The calculation of the adjustment value described below is performed on a keyword extracted from a message acquired during a predetermined time corresponding to the control cycle for each predetermined control cycle (the set temperature update cycle of the air conditioner 22). Based on.

  First, for a keyword indicating that the temperature is felt hot, a unit adjustment value (for example, −1 ° C.) in the direction of decreasing the set temperature, and for a keyword indicating that the temperature is felt cold, a unit in the direction of increasing the set temperature. An adjustment value (for example, + 1 ° C.) is determined in advance. And if a keyword is extracted from the message acquired during the predetermined time according to a control period, the adjustment value calculation part 14 will extract whether the above-mentioned modifier was extracted with the keyword. In some cases, the weight for the keyword is determined depending on whether the modifier is a high degree or a modifier showing a low degree. For example, if no modifier is extracted, the keyword weight corresponding to the modifier is 1, and if a modifier indicating that the degree is large is extracted, the keyword weight corresponding to the modifier is 1.5 and the degree is When a modifier that indicates a small value is extracted, the weight of the keyword corresponding to the modifier is determined to be 0.5.

  Furthermore, the adjustment value calculation unit 14 calculates the distance between the input position of the message including the keyword and the position of the target elevator, and determines the weight of the keyword according to the calculated distance. For example, the weight of the keyword corresponding to the distance is determined such that the maximum value is 1.5 and the minimum value is 0.5, and the weight becomes larger as the distance is smaller. For a keyword extracted from a voice message input from the microphone 25 in the car 20 of the target elevator or a voice or text message input using the message input unit 31 of the portable terminal 30 in the car 20 The weight corresponding to the distance takes the maximum value. Then, the adjustment value calculation unit 14 extracts the unit adjustment value corresponding to the keyword extracted from the message by multiplying the weight according to the modifier and the weight according to the distance, from the message. An individual adjustment value based on the keyword is calculated.

  Here, if there is one keyword extracted from the message acquired during the predetermined time according to the control cycle, the individual adjustment value based on the keyword calculated as described above is set to the set temperature of the air conditioner 22. Adjustment value. On the other hand, when there are a plurality of keywords extracted from messages acquired during a predetermined time corresponding to the control cycle and the individual adjustment values described above are calculated for each keyword, the adjustment value calculation unit 14 assigns each keyword to each keyword. By adding the individual adjustment values based on them and dividing by the number of keywords, an average value of these individual adjustment values is calculated and used as an adjustment value for the set temperature of the air conditioner 22.

  The adjustment value calculation method described above is merely an example, and the present invention is not limited to this. For example, in the above example, the keyword extracted from the message is weighted according to a modifier representing the degree of impression about temperature, or weighted according to the distance between the input position of the message and the position of the target elevator. However, such weighting may not be performed. Alternatively, weighting by another method may be performed instead of weighting by the above method or in addition to weighting by the above method.

  As an example of weighting by another method, for example, a person using the target elevator by the user of the mobile terminal 30 with respect to a keyword extracted from a message input from the mobile terminal 30 (for example, the target elevator is a corporate building) In the case of an elevator installed in the building, an example is given in which a high value is weighted when registered in advance as an employee who works in the building. Moreover, when the user of the portable terminal 30 makes an elevator use reservation for the keyword extracted from the message input from the portable terminal 30, an example is given in which a high value is given. Moreover, the example which weights according to the priority preset with respect to the user of the portable terminal 30 with respect to the keyword extracted from the message input with the portable terminal 30 is mentioned. Examples of the index for determining the priority include the user's health condition (including wheelchair users, white cane users, guide dog users, etc.), the user's position, the user's age, and the like. Such information may be input from the portable terminal 30 together with the message, or may be registered in advance. When weighting a keyword using the user information of the mobile terminal 30 as described above, the user information of the mobile terminal 30 is associated with the input message.

  The set temperature update unit 15 updates the set temperature of the air conditioner 22 of the target elevator based on the adjustment value calculated by the adjustment value calculation unit 14. For example, the set temperature update unit 15 acquires the current set temperature of the air conditioner 22 of the target elevator, and adds the adjustment value calculated by the adjustment value calculation unit 14 to the current set temperature, thereby adding a new value. Calculate the correct set temperature. Then, the set temperature update unit 15 generates an update command for the set temperature of the air conditioner 22 in which the new set temperature is specified, and transmits this update command from the communication unit 11 to the target elevator car 20. In response to the update command, the air conditioner 22 of the target elevator updates the current set temperature to a new set temperature specified by the update command. Further, the set temperature update unit 15 may transmit an update command specifying the adjustment value calculated by the adjustment value calculation unit 14. In this case, the air conditioner 22 of the target elevator updates the set temperature by adjusting the current set temperature based on the adjustment value specified by this update command.

  When the set temperature of the air conditioner 22 is changed, the elevator user in the car 20 of the target elevator may be notified that the set temperature of the air conditioner 22 has been updated. Examples of the notification method include display using a liquid crystal panel of an operation panel installed in the car 20, and sound output from a speaker installed in the car 20. In addition, a message including a keyword indicating that the temperature is felt hot is input to the liquid crystal panel of the operation panel installed in the car 20 together with an indication that the set temperature of the air conditioner 22 has been updated. Information related to the update of the set temperature, such as the number of people and the number of people who input a message including a keyword indicating that the temperature is felt cold, may be displayed.

  Next, operation | movement of the air-conditioning control apparatus 10 for elevators is demonstrated. FIG. 2 is a flowchart illustrating an example of a processing procedure performed by the elevator air-conditioning control apparatus 10 according to the present embodiment. The series of processes shown in the flowchart of FIG. 2 is repeatedly executed by the elevator air-conditioning control device 10 at every predetermined control cycle (the set temperature update cycle of the air-conditioning equipment 22).

  When the process shown in the flowchart of FIG. 2 is started, first, it is determined whether or not the message input unit 12 has acquired a message input within a predetermined area determined based on the position of the target elevator (step). S101). Then, when the message is acquired by the message acquisition unit 12 (step S101: Yes), it is determined whether or not a predetermined keyword representing an impression on the temperature is extracted from the message by the keyword extraction unit 13 (step S102). ). When a keyword is extracted by the keyword extraction unit 13 (step S102: Yes), the adjustment value calculation unit 14 performs a process of calculating an individual adjustment value based on the extracted keyword (step S103).

  FIG. 3 is a flowchart showing a specific example of the process of calculating the individual adjustment value in step S103 of FIG. When the processing shown in the flowchart of FIG. 3 is started, the adjustment value calculation unit 14 firstly, from the message acquired by the message acquisition unit 12, a modifier that represents the degree of impression on the temperature is combined with the keyword and the keyword extraction unit 13. (Step S201). When such a modifier is extracted together with the keyword (step S201: Yes), the adjustment value calculation unit 14 determines the weight of the keyword corresponding to the extracted modifier (step S202). On the other hand, if no modifier is extracted (step S201: No), the process of step S202 is skipped.

  Next, the adjustment value calculation unit 14 calculates the distance between the input position of the message acquired by the message acquisition unit 12 and the position of the target elevator (step S203). Then, the adjustment value calculation unit 14 determines the keyword weight according to the distance calculated in step S203 (step S204). Finally, the adjustment value calculation unit 14 multiplies the unit adjustment value corresponding to the keyword extracted from the message by the weight determined in step S202 or step S204, and the individual adjustment value based on the keyword extracted from the message. Is calculated (step S205).

  When the individual adjustment value is calculated in step S103 of FIG. 2, it is then determined whether or not a predetermined time corresponding to the control cycle has elapsed since the start of the process (step S104). Further, when the message acquisition unit 12 has not acquired a message (step S101: No) or when the keyword extraction unit 13 has not extracted a keyword from the message (step S102: No), the process proceeds to step S104. It is determined whether or not a predetermined time corresponding to the control cycle has elapsed since the start of the process. If the predetermined time has not elapsed (step S104: No), the process returns to step S101 and the subsequent processing is repeated. On the other hand, when a predetermined time according to the control cycle has elapsed since the start of the process (step S104: Yes), the adjustment value calculation unit 14 based on the individual adjustment value calculated in step S103 during the predetermined time, Processing for calculating an adjustment value for the set temperature of the air conditioner 22 of the target elevator is performed (step S105).

  FIG. 4 is a flowchart showing a specific example of the process of calculating the adjustment value in step S105 of FIG. When the process shown in the flowchart of FIG. 4 is started, the adjustment value calculation unit 14 first determines whether or not a plurality of individual adjustment values are calculated by the process of step S103 described above (step S301). If a plurality of individual adjustment values are calculated (step S301: Yes), an average value of the plurality of individual adjustment values is calculated, and this is used as an adjustment value for the set temperature of the air conditioner 22 (step S302). . On the other hand, if there is only one individual adjustment value calculated by the process of step S103 described above (step S301: No), the individual adjustment value is set as an adjustment value for the set temperature of the air conditioner 22 (step S303).

  When the adjustment value for the set temperature of the air conditioner 22 is calculated in step S105 of FIG. 2, next, the set temperature update unit 15 determines whether the adjustment value calculated in step S105 is not 0 (step S106). . If the adjustment value calculated in step S105 is 0 (step S106: No), the subsequent processing is skipped, and the series of processing shown in the flowchart of FIG. On the other hand, if the adjustment value calculated in step S105 is not 0 (step S106: Yes), the set temperature update unit 15 acquires the current set temperature set in the air conditioner 22 of the target elevator (step S107). ) By adding the adjustment value calculated in step S105 to the acquired current set temperature, a new set temperature is calculated (step S108). Then, the set temperature update unit 15 generates an update command for updating the set temperature of the air conditioner 22 of the target elevator with the new set temperature calculated in step S108, and transmits this update command to the target elevator ( Step S109). Thereby, the set temperature of the air conditioner 22 of the target elevator is updated, and a series of processes shown in the flowchart of FIG. 2 ends.

  As described above in detail with specific examples, in the present embodiment, the elevator air-conditioning control device 10 acquires a message input within a predetermined area defined with reference to the position of the target elevator. Thus, a predetermined keyword representing an impression on the temperature is extracted from this message. Then, the elevator air-conditioning control device 10 calculates an adjustment value for the set temperature of the air conditioner 22 of the target elevator based on the keyword extracted from the message, and the air conditioner 22 of the target elevator based on the calculated adjustment value. Update the set temperature. Therefore, according to the present embodiment, it is possible to appropriately control the air conditioner 22 installed in the car 20 of the target elevator, reflecting the impression that a person actually feels with respect to the temperature.

  Further, according to the present embodiment, a modifier that expresses the degree of impression with respect to temperature is extracted together with a keyword from a message that is input within a predetermined area that is determined based on the position of the target elevator, and the extracted modifier Since the adjustment value for the set temperature of the air conditioner 22 is calculated based on the weighted keywords, the impression that the person actually feels with respect to the temperature is more accurately reflected in the control of the air conditioner 22. Can be made.

  Further, according to the present embodiment, the adjustment value for the set temperature of the air conditioner 22 is calculated based on the keyword weighted according to the distance between the input position of the message from which the keyword is extracted and the position of the target elevator. Since it is doing, especially the impression with respect to the temperature of the person (elevator user) who is getting in or is likely to get into the car 20 of the target elevator can be accurately reflected in the control of the air conditioner 22. .

  Further, according to the present embodiment, when a plurality of keywords are extracted from a plurality of messages, the average value of the individual adjustment values corresponding to the extracted individual keywords is used as the adjustment value for the set temperature of the air conditioner 22. Since the calculation is made, it is possible to accurately reflect the impression of the temperature by a plurality of people in the control of the air conditioner 22.

[Second Embodiment]
Next, a second embodiment will be described. In the present embodiment, the elevator air-conditioning control device 10 accumulates an update history for the set temperature of the air conditioner 22 of the target elevator, and when a predetermined amount of update history is accumulated, creates an update schedule based on the update history. Thereafter, the set temperature of the air conditioner 22 is updated according to the update schedule. Since other functions are the same as those in the first embodiment described above, description overlapping with the first embodiment will be omitted as appropriate, and only differences from the first embodiment will be described.

  FIG. 5 is a block diagram illustrating a configuration example of an elevator air conditioning control system according to the second embodiment. In this embodiment, as shown in FIG. 5, the history database 18 and the schedule creation unit 19 are included in the elevator air-conditioning control device 10 (hereinafter, referred to as the elevator air-conditioning control device 10 ′ in distinction from the first embodiment). And have been added.

  The history database 18 associates the set temperature of the air conditioner 22 of the target elevator updated by the set temperature update unit 15 (hereinafter referred to as the set temperature update unit 15 ′ in distinction from the first embodiment) with the update time. Accumulated update history. The update history is created by, for example, associating the new set temperature specified by the update command with the transmission time of the update command when the set temperature update unit 15 ′ transmits the above update command from the communication unit 11 to the target elevator. And stored in the history database 18. The history database 18 is constructed using a storage device such as an HDD.

  The schedule creation unit 19 creates an update schedule to be applied to the air conditioner 22 of the target elevator based on the update history accumulated in the history database 18 when a predetermined amount of update history is accumulated in the history database 18. The update schedule defines the set temperature of the air conditioner 22 according to the time. Here, the predetermined amount is a sufficient amount for performing statistical processing on the update history, and an appropriate value may be determined in advance. For example, the schedule creation unit 19 estimates a comfortable temperature for each time that a person feels comfortable by statistically processing a predetermined amount of update history accumulated in the history database 18. For example, an average value of set temperatures for each update time included in a predetermined amount of update history is estimated as a comfortable temperature for each time. Then, the required time (predetermined time determined according to the characteristics of the air conditioner 22) from when the set temperature of the air conditioner 22 is updated until the temperature inside the car 20 actually becomes the comfortable temperature corresponds to the comfortable temperature. By associating the estimated comfortable temperature as the set temperature of the air conditioner 22 with the time subtracted from the time, an update schedule that defines the set temperature of the air conditioner 22 according to the time is created.

  The set temperature update unit 15 ′ in the present embodiment updates the set temperature of the air conditioner 22 of the target elevator by the same method as in the first embodiment until the update schedule is created by the schedule creation unit 19. (Hereinafter, this is referred to as “message response type update control”). Then, after the update schedule is created by the schedule creation unit 19, the set temperature of the air conditioner 22 of the target elevator is updated according to this update schedule (hereinafter referred to as “schedule-linked update control”).

  FIG. 6 is a flowchart showing an outline of the operation of the elevator air-conditioning control apparatus 10 ′ of this embodiment. In the present embodiment, for the air conditioner 22 of the target elevator, the set temperature update unit 15 ′ first updates the set temperature by message response type update control (step S401), and the update history is accumulated in the history database 18. (Step S402). Then, the schedule creation unit 19 determines whether or not a predetermined amount of update history has been accumulated in the history database 18 (step S403), and if the predetermined amount of update history has not been accumulated (step S403: No), step Returning to S401, the subsequent processing is repeated.

  On the other hand, when a predetermined amount of update history is accumulated in the history database 18 (step S403: Yes), the schedule creation unit 19 is applied to the air conditioner 22 of the target elevator based on the update history accumulated in the history database 18. An update schedule to be created is created (step S404). Then, after the update schedule is created, the set temperature update unit 15 'updates the set temperature by the schedule-linked update control for the air conditioner 22 of the target elevator (step S405).

  As described above, according to the present embodiment, an update history for the set temperature of the air conditioner 22 of the target elevator is accumulated, and when a predetermined amount of update history is accumulated, an update schedule is created based on the update history. Then, since the set temperature of the air conditioner 22 is updated according to the update schedule, the same effect as that of the first embodiment can be obtained while reducing the processing load of the elevator air conditioning control device 10 ′. Can do.

  In the above description, until a predetermined amount of update history is accumulated in the history database 18 and an update schedule is created, the set temperature is updated by message response type update control for the air conditioner 22 of the target elevator. Like to do. However, even if the target elevator does not have an update schedule, if an update schedule has been created for another elevator that has similar environmental conditions to the elevator (hereinafter referred to as “similar property”), An update schedule created for this similar property may be used to update the set temperature for the air conditioner 22 of the target elevator by schedule-linked update control. Here, the environmental conditions are similar, for example, the use of the building where the elevator is installed (for example, a station building, a nursing home, etc.) and the sunshine situation are the same, and the location of the building where the elevator is installed is close Say. Similar properties having similar environmental conditions to the target elevator can be identified by referring to the property database 16 described above.

  FIG. 7 is a flowchart showing an outline of the operation of the elevator air-conditioning control apparatus 10 'in such a case. In this example, first, it is determined whether or not an update schedule has been created for the target elevator (step S501). And when the update schedule is created (step S501: Yes), it progresses to step S508 and setting temperature update part 15 'is set temperature by schedule interlocking type update control with respect to the air conditioner 22 of object elevator. Update.

  On the other hand, if an update schedule is not created for the target elevator (step S501: No), a similar property with similar environmental conditions to the target elevator is searched, and an update schedule is created for the similar property. It is determined whether or not (step S502). And when the update schedule is created with respect to a similar property (step S502: Yes), preset temperature update part 15 'acquires the update schedule of this similar property (step S503), and progresses to step S508. The set temperature is updated by the schedule-linked update control by applying the update schedule of the similar property to the air conditioner 22 of the target elevator.

  On the other hand, when the update schedule is not created for the similar property (step S502: No), the set temperature update unit 15 ′ updates the set temperature by the message response type update control for the air conditioner 22 of the target elevator. (Step S504), and the update history is accumulated in the history database 18 (Step S505). Then, the schedule creation unit 19 determines whether or not a predetermined amount of update history has been accumulated in the history database 18 (step S506), and if the predetermined amount of update history has not been accumulated (step S506: No), step Returning to S504, the subsequent processing is repeated.

  On the other hand, when a predetermined amount of update history is accumulated in the history database 18 (step S506: Yes), the schedule creation unit 19 is applied to the air conditioner 22 of the target elevator based on the update history accumulated in the history database 18. An update schedule to be created is created (step S507). Then, after the update schedule is created, the process proceeds to step S508, and the set temperature update unit 15 'updates the set temperature by the schedule-linked update control for the air conditioner 22 of the target elevator.

  According to this example, the set temperature can be updated by the schedule-linked update control for the air conditioning equipment 22 of the target elevator for which no update schedule has been created. The load can be further reduced.

[Modification]
Below, the modification which applied embodiment mentioned above is demonstrated. When the target elevator is an elevator that is used only by a specific user such as a home elevator, for example, as the history database 18 described in the second embodiment, a database that stores update histories corresponding to the specific user (hereinafter, “ A personal database). Also, by tracking the behavior of the specific user based on the location information of the mobile terminal 30 possessed by the specific user, the elevator usage history of the specific user is created and stored in the personal database along with the update history can do. An update schedule for a specific user can be created based on the update history and elevator use history of the specific user stored in these personal databases.

  For example, the update temperature accumulated in the personal database is statistically processed to estimate the comfortable temperature for each time that the specific user feels comfortable. Moreover, the boarding time when a specific user gets into the car 20 of the target elevator is predicted based on the elevator use history of the specific user stored in the personal database. The specific use is made by associating the comfortable temperature corresponding to the boarding time with the time obtained by subtracting the time required for the temperature in the car 20 to become the comfortable temperature after the set temperature of the air conditioner 22 is updated. An update schedule for users.

  For the air conditioner 22 of the target elevator that is used only by a specific user, the specific user is updated by updating the set temperature (schedule-linked update control) according to the update schedule for the specific user. At the timing of getting into the car 20, the temperature in the car 20 can be controlled to a temperature at which the specific user is expected to feel comfortable.

  FIG. 8 is a flowchart illustrating this modification. In this modification, first, a personal database in which an update history corresponding to a specific user is accumulated is constructed (step S601). Then, the elevator usage history of the specific user is accumulated in this personal database (step S602). Thereafter, it is determined whether or not a predetermined amount of elevator use history has been accumulated in the personal database (step S603). If a predetermined amount of elevator use history has not been accumulated (step S603: No), the process returns to step S602 to return to the elevator. The process of accumulating usage history is repeated.

  On the other hand, when a predetermined amount of elevator usage history is accumulated in the personal database (step S603: Yes), the identification applied to the air conditioner 22 of the target elevator based on the update history and elevator usage history accumulated in the personal database. An update schedule for the user is created (step S604). Then, the set temperature of the air conditioner 22 of the target elevator is updated by schedule-linked update control using the update schedule for the specific user (step S605).

  In addition, the specific user using the target elevator as described above is usually not limited to one person, and there are often many specific users. That is, if it is a home elevator, this is a family, and if it is an elevator dedicated to a company employee, this is a company employee. In this case, since an update schedule for a specific user is created for each specific user, the update schedules of a plurality of specific users may conflict with each other depending on the time period.

  Therefore, in the time period when the update schedules of multiple specific users compete, it is decided which specific user's update schedule should be given priority based on the priority set in advance for each specific user. It is desirable to do. That is, in the time zone when a plurality of specific users get on the car 20 of the target elevator, the setting of the air conditioner 22 of the target elevator is performed by schedule-linked update control according to the update schedule of the specific user having the highest priority. Update temperature. As an index for determining priority, for example, as described above, the health status of a specific user (including wheelchair users, white cane users, guide dog users, etc.), the position of the specific user (corporate title, etc.), Examples include the age of specific users.

  Moreover, in the time zone in which the update schedules of a plurality of specific users compete, for example, an average value of individual set temperatures indicated by these update schedules is obtained, and the set temperature of the air conditioner 22 of the target elevator is the average value. You may control so that it may become.

  According to at least one embodiment described above, it is possible to appropriately control the air conditioner installed in the elevator car by reflecting the impression that a person actually feels with respect to the temperature.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
