Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE An embodiment of the present invention relates to an elevator system. [Background technology]

[0002] In recent years, a system in which users who have used a desired service post reviews (ratings / word of mouth) about the service has become widespread. With this system, service providers can refer to reviews posted by users to improve and enhance their services. In addition, other users can refer to reviews posted by users to decide whether or not to use a desired service.

[0003] However, posting a review is time-consuming, and there is a problem in that only a portion of users who have used a desired service post a review.

[0004] Incidentally, elevator users tend not to use smartphones or the like much while in the elevator, and tend to waste time (i.e., tend to waste idle time) until the elevator arrives at the destination floor. [Prior art documents] [Patent documents]

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the disclosure is merely an example, and the invention is not limited to the contents described in the following embodiments. Modifications that a person skilled in the art can easily conceive are naturally included in the scope of the disclosure. In order to make the explanation clearer, the size, shape, etc. of each part may be changed from the actual embodiment and shown diagrammatically. In multiple drawings, corresponding elements may be given the same reference numerals, and detailed explanations may be omitted.

[0010] In this embodiment, an elevator system is described that cooperates with a service providing system that provides a desired service to a user, and is capable of feeding back reviews (ratings and word-of-mouth on the desired service) by users who have used the desired service to the service providing system. In this embodiment, it is assumed that the service providing system is a travel reservation system that can provide (suggest) a desired travel plan to a user and make reservations for the travel plan. A travel plan is an example of a trip provided to a user from a travel reservation system, and indicates, for example, a travel destination, a means of transportation to the travel destination (for example, a bullet train, a bus, an airplane, etc.), accommodation at the travel destination, meals at the travel destination, etc. A user can make a trip according to the travel plan by reserving (using) such a travel plan.

[0011] In this embodiment, it is assumed that the service providing system is a travel reservation system, but this is not limited to this, and the service providing system may be any system that is capable of providing users with the desired service.

[0012] Fig. 1 is a diagram showing a schematic configuration example of an information processing system including an elevator system according to this embodiment. As shown in Fig. 1, the information processing system includes an elevator system 1 and a travel reservation system 2. First, the configuration included in the elevator system 1 will be described below.

[0013] A camera 12 is installed above the entrance of the car 11. Specifically, the camera 12 is installed in a fascia 11a covering the upper part of the entrance of the car 11 with the lens portion facing directly downward. The camera 12 has an ultra-wide-angle lens such as a fisheye lens, and captures a wide range of the subject including the inside of the car 11 with a viewing angle of 180 degrees or more. The camera 12 can continuously capture several frames per second (e.g., 30 frames / second).

[0014] The location of the camera 12 does not have to be above the entrance of the car 11, so long as it is near the car door 13. For example, the camera 12 may be installed in any location, such as the ceiling surface near the entrance of the car 11, that can capture an image of the entire car interior including the entire floor area inside the car 11 and the landing 15 near the entrance when the door is open.

[0015] The car 11 is provided with an in-car display device 14 (e.g., signage) having a so-called touch panel function. Although details will be described later, the in-car display device 14 displays video content (or image content) including a request for a review of a travel plan provided by the travel reservation system 2.

[0016] At the landing 15 on each floor, a landing door 16 is installed at the arrival gate of the car 11. The landing door 16 engages with the car door 13 when the car 11 arrives and opens and closes. The power source (door motor) is on the car 11 side, and the landing door 16 simply opens and closes following the car door 13.

[0017] In this embodiment, a user registers call information using a call registration application (hereinafter, referred to as a call registration application) 3a preinstalled on the user's mobile terminal 3 (e.g., a smartphone or a tablet terminal). The call registration application 3a is, for example, an application developed by a company related to the elevator system 1, and can be freely downloaded from a website that depends on the OS (Operating System) of the mobile terminal 3.

[0018] A user can launch the call registration app 3a and input the boarding floor and destination floor (boarding information) (or by setting the boarding information in advance in the call registration app 3a), and register (send) the call information, which includes the boarding information and the user's unique user ID, to the elevator control device 30.

[0019] The user-specific user ID may be a user ID assigned to each user by the call registration application 3a, but it is preferable to use the terminal ID of the mobile terminal 3 on which the call registration application 3a is installed as the user-specific user ID. This makes it possible to standardize the user ID included in the call information and the user ID managed in the travel reservation system 2, eliminating the need to link these two user IDs, which is necessary to make the elevator system 1 and the travel reservation system 2 work together.

[0020] In addition, in the present embodiment, the user registers the call information using the call registration application 3a, but the present invention is not limited to this, and the call information may be registered in any manner as long as the call information including the boarding information and the user's unique user ID can be registered. For example, the user may register the call information including the boarding information and the user's unique user ID by holding an IC card on which the boarding information and the user's unique user ID are recorded over a hall destination floor registration device (HDC: Hall Destination Controller) installed at the hall.

[0021] The elevator control device 30 has a communication function for communicating with other devices (for example, the mobile terminal 3, the user detection device 20 and the cloud server 40 described later). The elevator control device 30 controls the operation of the car 11 in response to the registered call information. In this embodiment, when the elevator control device 30 receives call information transmitted from the mobile terminal 3 using the above-mentioned call registration application 3a, the elevator control device 30 registers the call information in a memory (not shown) and causes the car 11 to respond to the boarding floor indicated by the call information. The elevator control device 30 also controls the opening and closing of the car door 13 when the car 11 arrives at the boarding floor or the destination floor, and controls the lighting of the lighting equipment in the car 11.

[0022] The user detection device 20 has a communication function for communicating with other devices (e.g., the camera 12 and the elevator control device 30). The user detection device 20 executes a process of analyzing, in real time, each image (video) continuously captured by the camera 12. For this reason, the user detection device 20 may be referred to as an image processing device or an image analysis device. As shown in FIG. 1, the user identification device 20 includes a memory unit 21, a user identification unit 22, and a passenger number detection unit 23.

[0023] The storage unit 21 sequentially stores images captured by the camera 12. The storage unit 21 also stores (holds) the above-mentioned user ID unique to the user and attribute information of the user identified by the user ID in advance in association with each other as data necessary for processing by the user identification unit 22. The attribute information is information indicating the characteristics of the user, such as the user's gender, the user's age, a facial image of the user, special notes (e.g., wheelchair user, stroller user, etc.).

[0024] The user identification unit 22 executes a process of determining whether or not a user appearing in an image captured by the camera 12 is a user who has registered call information in the elevator control device 30 (a person who has registered the call information). More specifically, the user identification unit 22 compares the image captured by the camera 12 with attribute information that is pre-stored in the storage unit 21 and that is associated with a user ID indicated by the call information registered in the elevator control device 30, and determines whether or not the user appearing in the image is a person who has registered the call information based on whether or not the characteristics of the user appearing in the image match the characteristics of the user indicated by the attribute information.

[0025] The passenger number detection unit 23 detects the number of passengers riding in the elevator 11 based on the image captured by the camera 12, and performs a process to determine whether the passengers riding in the elevator 11 are only those registered in the above-mentioned call information (i.e., performs a process to detect the riding of one person registered in the call information).

[0026] The results of the above-mentioned processing by the user identification unit 22 and the passenger number detection unit 23 are notified to the elevator control device 30, and are also notified via the elevator control device 30 to a cloud server 40, which will be described later.

[0027] The cloud server 40 is a server provided on a cloud constructed by an associated company of the elevator system 1. The cloud server 40 distributes video content including a request for a review of a travel plan to a user who has booked a travel plan provided by the travel reservation system 2 and traveled according to the travel plan. In addition, the cloud server 40 executes a process of feeding back (transmitting) review information including a review input by the user to the travel reservation system 2 in response to the review request included in the video content. The detailed configuration of the cloud server 40 will be described later. In addition, hereinafter, a "user who has booked a travel plan provided by the travel reservation system 2 and traveled according to the travel plan" may be simply referred to as a "user who used a travel plan provided by the travel reservation system 2."

[0028] Next, the configuration of the travel reservation system 2 will be described. As shown in FIG. 1, the travel reservation system 2 includes a history information storage unit 2a and a content information storage unit 2b.

[0029] The history information storage unit 2a stores history information indicating the history of reservations for travel plans made by users using a website or application (hereinafter referred to as a travel app) provided by the travel reservation system 2. Here, an example of the data structure of the history information will be described with reference to FIG.

[0030] Fig. 2 is a diagram showing an example of a data structure of history information. As shown in Fig. 2, the history information is information including a user ID, reservation history information, and review history information in association with each other. Note that the data structure of the history information is not limited to the data structure shown in Fig. 2, and other information may be associated with the history information.

[0031] The user ID is information for identifying a user who has made a reservation for a travel plan on a website or travel app provided by the travel reservation system 2. The user ID may be a user ID assigned to each user by the travel reservation system 2, but similar to the user ID included in the above-mentioned call information, it is preferable to use the terminal ID of the mobile terminal 3 that has made the reservation for the travel plan on a website or travel app provided by the travel reservation system 2 as a user-specific user ID.

[0032] The reservation history information is information that indicates the history of travel plan reservations made by users using a website or travel app provided by the travel reservation system 2, and indicates, for example, the date the travel plan was booked, the reservation details (travel plan name), travel dates, etc.

[0033] The review history information is information indicating whether or not a user has posted a review (review posting history), and indicates, for example, whether or not a review is posted (review posted) or not (review not posted).

[0034] For example, the history information d1 shown in Figure 2 indicates that a user identified by the user ID "U_id001" booked "Travel Plan A" on "January 1, 2023" for the dates "February 1, 2023 - February 3, 2023," and that there are "no" reviews for "Travel Plan A" by the user.

[0035] Returning to the explanation of FIG. The content information storage unit 2b stores video content including a request for a review of a travel plan provided by the travel reservation system 2. Here, an example of the data structure of content information including the above-mentioned video content will be described with reference to Fig. 3.

[0036] Fig. 3 is a diagram showing an example of the data structure of content information. As shown in Fig. 3, the content information is information including a content ID, video content, and summary information in association with each other. Note that the data structure of the content information is not limited to the data structure shown in Fig. 3, and other information may be associated with the content information.

[0037] The content ID is information for identifying the video content that includes a request for a review of a desired travel plan.

[0038] The summary information is information that indicates an overview of the video content described above, and indicates at least which travel plan the review request is about.

[0039] For example, the content information d2 shown in FIG. 3 indicates that "video content C1" identified by the content ID "C_id001" is video content including "request for review of travel plan A."

[0040] Next, a detailed configuration of the cloud server 40 will be described with reference to FIG. As shown in FIG. 4, the cloud server 40 includes a history information storage unit 41, a content information storage unit 42, a reservation history checking unit 43, a review history checking unit 44, a content delivery control unit 45, and a review feedback unit 46.

[0041] The history information storage unit 41 stores history information provided by the travel reservation system 2. In other words, the history information storage unit 41 is a storage device similar to the history information storage unit 2a of the travel reservation system 2. The history information storage unit 41 may store only history information related to users who have not reviewed the travel plan they have reserved (used), among the history information stored in the history information storage unit 2a of the travel reservation system 2. This makes it possible to reduce the amount of data of the history information stored in the history information storage unit 41.

[0042] The content information storage unit 42 stores content information provided by the travel reservation system 2. In other words, the content information storage unit 42 is a storage device similar to the content information storage unit 2b of the travel reservation system 2.

[0043] The reservation history confirmation unit 43 determines whether the user who registered the call information has made a reservation for the travel plan based on the user ID included in the history information. The reservation history confirmation unit 43 also determines whether the person who registered the call information has already traveled with the reserved travel plan based on the reservation history information included in the history information.

[0044] The review history checking unit 44 determines whether or not the person who registered the call information has reviewed the travel plan that he or she booked (used), based on the review history information contained in the history information.

[0045] The content distribution control unit 45 executes a process of distributing video content including a request for a review of the travel plan to the car interior display device 14 when (1) the registrant of the call information rides alone in the car 11, (2) the registrant uses a travel plan provided by the travel reservation system 2, and (3) the registrant has not reviewed the travel plan. Note that if new call information by another user is registered in the elevator control device 30 while the video content is being distributed to the car interior display device 14, the content distribution control unit 45 terminates the distribution of the video content from the viewpoint of privacy protection.

[0046] The review feedback unit 46 acquires review information including reviews entered by the call information registrant in response to a review request contained in the video content distributed to the car interior display device 14, and performs a process of feeding back (sending) this information to the service provision system 2.

[0047] Here, a series of processes executed by the elevator system 1 according to this embodiment will be described with reference to the flowchart in Fig. 5. Fig. 5 is a flowchart showing a series of processes from when call information is registered by a user to when review information including a review by the user is fed back to the travel reservation system 2.

[0048] First, when the elevator control device 30 receives call information transmitted from the mobile terminal 3 in response to a user's call registration operation, it registers the call information in a memory not shown, and causes the elevator car 11 to respond to the boarding floor indicated by the call information (step S1).

[0049] When the elevator car 11 arrives at the boarding floor and the elevator car door 13 of the elevator car 11 opens, the camera 12 installed in the elevator car 11 takes an image including a user at the landing 15. The user identification unit 22 of the user detection device 20 analyzes the image taken by the camera 12 and determines whether the user shown in the image is the user who registered the call information in step S1.

[0050] More specifically, first, the user identification unit 22 compares the image captured by the camera 12 with attribute information previously stored in the storage unit 21 and associated with the user ID indicated by the call information registered in step S1. Then, the user identification unit 22 determines whether the user shown in the image is a registered user of the call information based on whether the characteristics of the user shown in the image match the characteristics of the user indicated by the attribute information described above (step S2).

[0051] In step S2, if the characteristics of a user shown in the image taken by camera 12 match the characteristics of a user indicated by the attribute information and it is determined that the user shown in the image is a person registered in the call information (Yes in step S2), the passenger number detection unit 23 detects the number of users riding in the elevator 11 based on the image taken by camera 12, and determines whether the only users riding in the elevator 11 are people registered in the call information (step S3).

[0052] In step S3, if it is determined that the only users riding in the car 11 are those who have registered the call information (Yes in step S3), the user detection device 20 transmits, as a result of steps S2 and S3, a notification that the person who has registered the call information is riding alone in the car 11 (hereinafter referred to as a "single person riding notification") to the elevator control device 30. Upon receiving the single person riding notification transmitted from the user detection device 20, the elevator control device 30 transmits the single person riding notification and the call information registered in step S1 to the cloud server 40.

[0053] When the reservation history checking unit 43 of the cloud server 40 receives the solo boarding notification and the call information transmitted from the elevator control device 30, the reservation history checking unit 43 determines whether the registrant of the call information has made a reservation for a travel plan provided by the travel reservation system 2 based on the presence or absence of history information including the user ID indicated by the call information (step S4). Note that when history information including the user ID indicated by the received call information is stored in the history information storage unit 41, the reservation history checking unit 43 determines that the registrant of the call information has made a reservation for a travel plan.

[0054] In step S4, if it is determined that the registrant of the call information has made a reservation for a travel plan (Yes in step S4), the reservation history confirmation unit 43 determines whether the registrant of the call information has already traveled with the reserved travel plan based on the reservation history information associated with the user ID indicated by the call information (step S5). If the current date is a date later than the travel schedule indicated by the reservation history information, the reservation history confirmation unit 43 determines that the registrant of the call information has already traveled with the reserved travel plan.

[0055] In step S5, if it is determined that the registrant of the call information has already traveled with the booked travel plan (Yes in step S5), the review history confirmation unit 44 determines whether the registrant of the call information has reviewed the travel plan based on the review history information associated with the user ID indicated by the call information (step S6).

[0056] In step S6, if it is determined that the registrant of the call information has not reviewed the travel plan that he or she reserved (used) (No in step S6), the content distribution control unit 45 selects content information including video content corresponding to the travel plan used by the registrant of the call information from among the many pieces of content information stored in the content information storage unit 42, and distributes the video content included in the content information to the car interior display device 14 (step S7). As a result, the video content including a request for a review of the travel plan used by the registrant of the call information is displayed on the car interior display device 14.

[0057] Thereafter, the review feedback unit 46 acquires review information including reviews input by the call information registrant via the car interior display device 14 in response to a review request contained in the video content distributed to the car interior display device 14, and feeds back the review information to the travel reservation system 2 (step S8), thereby completing this series of processes.

[0058] In addition, in the above-mentioned step S5, if it is determined that the registrant of the call information has already traveled according to the reserved travel plan, the reservation history confirmation unit 43 may further execute a process of determining whether or not the time that has elapsed since the registrant of the call information traveled is equal to or less than a preset threshold value (e.g., one week) based on the reservation history information associated with the user ID indicated by the call information. In this way, the video content including the review request can be delivered only to users who have recently traveled (i.e., users who have vivid memories of the travel).

[0059] FIG. 6 is a diagram showing an example of video content displayed on the car interior display device 14. FIG. 6 shows a case where video content including a message of thanks for using "travel plan A" and a request for a review of "travel plan A" is displayed on the car interior display device 14. By touching the screen of the car interior display device 14, the user can rate the "satisfaction" of the travel plan A, for example, on a five-point scale (one star to five stars). In addition, by touching the screen of the car interior display device 14, the user can also cause an input interface (not shown) for inputting characters to be further displayed on the car interior display device 14, and input "impressions" of the travel plan A. By inputting the "satisfaction" and "impressions" and touching the review submission button b1, the user can transmit (post) a review of "travel plan A" including the input "satisfaction" and "impressions" to the cloud server 40.

[0060] The video content displayed on the car interior display device 14 may include a coupon issue button b2 for issuing a coupon, as shown in Fig. 7. This allows a service to be provided in which a coupon is issued (sent) to the mobile terminal 3 of a user when the coupon issue button b2 is touched by the user, which is expected to increase the probability that the user will post a review.

[0061] In the present embodiment described above, the content distribution control unit 45 distributes video content including a request for a review of the travel plan used by the registrant to the car interior display device 14 only when the registrant of the call information is riding alone in the car 11, but this is not limited thereto, and the above-mentioned video content may be distributed to the car interior display device 14 even when only the registrant of the call information and his / her child are riding in the car 11. Note that, for example, by registering in advance in the special notes of the attribute information stored in the storage unit 21 of the user detection device 20 that the user is a stroller user or has a child, the determination can be made at the same time as determining whether the user shown in the image is the registrant of the call information.

[0062] In addition, in this embodiment, the content distribution control unit 45 distributes video content including a request for a review of the travel plan used by the registrant of the call information to the car interior display device 14 when the registrant of the call information is riding alone in the car 11, but this is not limited to this, and the content distribution control unit 45 may also distribute the above-mentioned video content to the car interior display device 14 when the registrant of the call information is riding alone in the car 11 and the riding time of the registrant is equal to or longer than a predetermined threshold value.

[0063] According to this, it is possible to prevent video content including a review request from being distributed to users whose ride time is less than a preset threshold (i.e., users whose ride time is short). If video content including a review request is distributed to a user whose ride time is short, the user may feel uncomfortable, but by doing as described above, it is possible to prevent such a situation from occurring. The ride time of the person who registered the call information can be estimated based on the ride information (boarding floor and destination floor) indicated by the call information obtained from the elevator control device 30.

[0064] In addition, the content distribution control unit 45 may distribute video content including a request for a review of the travel plan used by the registrant to the car interior display device 14 only when it is detected that the registrant of the call information is riding alone in a car 11 near his / her home.

[0065] According to this, even if it is detected that the registrant of the call information is alone in a car 11 other than the one near his / her home, for example, the car 11 at his / her workplace, it is possible to prevent the delivery of video content including a review request. If video content including a review request is delivered to a user during working hours, the user may feel uncomfortable, but by doing as described above, it is possible to prevent such a situation from occurring. Note that, whether the car 11 in which the registrant of the call information is riding is the car 11 near the registrant's home can be determined, for example, by comparing location information indicating the home location preset in the call registration application 3a with the installation location (installation place) of the elevator control device 30 in which the call information is registered using the call registration application 3a.

[0066] Furthermore, the content distribution control unit 45 may distribute video content including a request for a review of a travel plan used by a registered user to the car interior display device 14 only when it is detected that the registered user of the call information is riding alone in the car 11 during a predetermined time period. For example, if video content including a review request is distributed to a user during a busy time period such as a weekday morning, the user may feel uncomfortable, but by doing as described above, it is possible to prevent such a situation from occurring.

[0067] Furthermore, the content delivery control unit 45 may deliver video content to allow the registrant of the call information to use (reserve) the same travel plan (or a similar travel plan) again a certain period of time (e.g., one year later or the next season) after using a travel plan provided by the travel reservation system 2. The period of time that has elapsed since the registrant of the call information used the above-mentioned travel plan can be calculated based on the reservation history information associated with the user ID of the registrant.

[0068] An example of the timing at which the content distribution control unit 45 distributes video content including a review request is when the person who registered the call information gets on the elevator 11 alone to check out of an accommodation facility at the travel destination of the booked travel plan.

[0069] As described above, the elevator system 1 of this embodiment cooperates with a service providing system such as a travel reservation system 2, delivers video content including a request for a review of a service to a user who has used the service provided by the service providing system, and feeds back review information including a review entered by the user in response to the review request to the service providing system. In other words, according to the embodiment described above, an elevator system can be provided that enables passengers to effectively utilize their time in the elevator and provides an opportunity to post reviews about desired services.

[0070] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
