[Technical Field]

[0001] The present invention relates to an elevator display control system and a display control method. [Background technology]

[0002] Conventionally, there is known a system in which an image of the outside of the elevator is displayed on a display device installed in the elevator car in synchronization with the ascending and descending movement of the car. For example, Patent Document 1 discloses a video information system for an elevator in which an image of the outside that corresponds to at least one of the season, date and time, or weather is displayed on a display device in the car in synchronization with the ascending and descending movement of the car. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3484731 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the above-mentioned Patent Document 1 discloses a technology in which elevator guide images for each floor that match the elevator running time are stored, and a display control device selects the next floor guide image based on the elevator start signal, next floor information, and estimated waiting time information until the next floor, and displays it on a display device inside the car.

[0005] However, the technology in Patent Document 1 requires that elevator guide images (next floor guide images) corresponding to each running pattern, which is determined by the running time and running speed, etc., be prepared in advance, which could result in an enormous amount of data to be stored.

[0006] The present invention has been made in consideration of the above situation, and an object of the present invention is to enable a display corresponding to the display area inside the car to be displayed in conjunction with the raising and lowering movement of the car. [Means for solving the problem]

[0007] An elevator display control system according to one aspect of the present invention is an elevator display control system that displays an image in a display area inside an elevator car. The elevator display control system according to one aspect of the present invention includes a car height position information acquisition unit that acquires car height position information that indicates the absolute position of the car in the height direction inside the elevator shaft, and a depiction unit that displays a group of images having height position information corresponding to the car height position information acquired by the car height position information acquisition unit in a display area inside the car. The car height position information acquisition unit corrects the acquired car height position information using information about the height of the building in which the elevator is installed, and further includes a resolution setting unit that sets the resolution of the image to be extracted from the image group based on information about the size and position of the display area, and an image group acquisition unit that reads out from the memory unit and outputs the image group with the resolution determined by the resolution setting unit. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, examples of modes for carrying out the present invention (hereinafter referred to as "embodiments") will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments, and various numerical values ​​in the embodiments are merely examples. Furthermore, in this specification and drawings, identical components or components having substantially the same functions will be designated by the same reference numerals, and redundant explanations will be omitted.

[0011] <Outline of elevator system configuration> First, the configuration of an elevator system 100 according to one embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of a schematic configuration of the elevator system 100.

[0012] 1, an elevator system 100 (an example of an elevator display control system) includes a car 1, an elevator control device 2, an archiver 3, and a drawing device 4. The car 1, the elevator control device 2, the archiver 3, and the drawing device 4 are communicatively connected to each other via a network N.

[0013] [Basket] The car 1 carries passengers or baggage (not shown) and moves up and down in a hoistway (not shown). The car 1 includes a speaker 11, an in-car display 12, a camera 13, and a position detector 14.

[0014] The speaker 11 emits a predetermined announcement or the like under the control of the elevator control device 2.

[0015] The car interior display 12 is a display device made up of a liquid crystal panel, an organic electroluminescence panel, or the like, and displays the destination floor, an arrow indicating the direction of ascent, etc. The car interior display 12 also displays a group of images transmitted from the imaging device 4, images captured by the building camera 5, or images captured by the maintenance camera 6 of various devices in the elevator shaft.

[0016] The camera 13 captures an image of the inside of the car 1 to generate a video signal, and transmits the video signal to the elevator control device 2.

[0017] Position detector 14 is installed on the upper or lower part of the outer surface of car 1 and detects the absolute position of car 1 within the hoistway. Position detector 14 detects the current height position of car 1 within the hoistway and the floor on which it is stopped, based on the absolute position (e.g., height from the bottom of the hoistway) detected by, for example, a magnetic sensor that reads a magnetic tape (not shown) installed within the hoistway or a photoelectric sensor that detects the position of a hole in a shielding plate (not shown) installed within the hoistway, and initial value information. Position detector 14 transmits the detected height position information of car 1 (hereinafter also referred to as absolute position detection information) to elevator control device 2.

[0018] The elevator control device 2 is installed in a machine room or a hoistway of the elevator (not shown), and controls the operation of the car 1. The elevator control device 2 includes an input / output information receiving unit 21 and a data output unit 22.

[0019] The input / output information receiving unit 21 receives absolute position detection information of the car 1 transmitted from the car 1 and outputs it to the data output unit 22, and also receives a group of images transmitted from the imaging device 4 and outputs it to the data output unit 22. Furthermore, the input / output information receiving unit 21 receives images captured by the building camera 5 and images captured by the maintenance camera 6 of various devices in the elevator shaft and outputs them to the data output unit 22.

[0020] The data output unit 22 transmits the absolute position detection information of the car 1 input from the input / output information receiving unit 21 to the imaging device 4, and transmits the image group or various captured videos input from the input / output information receiving unit 21 to the car in-car display 12 of the car 1. Note that in this embodiment, the illustration of the various functional units in the elevator control device 2 that control the operation of the car 1 is omitted.

[0021] The building camera 5 is installed, for example, on the outside of the car 1 so as to be able to photograph the outside of the building, and photographs the scenery outside the building. When the present invention is applied to an observation elevator whose elevator shaft is covered with glass or is exposed to the outside, a configuration in which the building camera 5 is installed directly on the car is envisioned.

[0022] Alternatively, the building camera 5 may be provided on the wall of the building independently of the car 1 and have a lifting mechanism that rises and falls in synchronization with the lifting and lowering movement of the car 1, or may be composed of multiple cameras provided at multiple height positions.

[0023] The maintenance camera 6 is provided, for example, on the outside of the car 1, and moves up and down in conjunction with the up and down movement of the car 1, while capturing images of the states of various devices in the elevator shaft.

[0024] The archiver 3 (an example of a storage unit) is provided, for example, in a server (not shown) provided in an external facility or a cloud environment, and stores various data. The archiver 3 is provided with a data management unit 30, which stores information such as an ID 31, location information 32, an image group 33, and height information 34.

[0025] The ID 31 indicates an ID for identifying the building the elevator is installed in. The location information 32 indicates the location information of the building, and is configured, for example, by positioning information obtained by a GPS (Global Positioning System).

[0026] The image group 33 is composed of images of scenery outside the building captured in the past by a drone or other camera (not shown), images of scenery at tourist spots (an example of another location), etc. The image group 33 includes, for example, images captured according to time periods such as morning, afternoon, and night, and images captured at multiple different time periods (periods, years). A method for capturing the scenery outside the building and an example of an image group obtained by such capturing will be described later with reference to FIG. 3. The height information 34 is information indicating the physical height of the building.

[0027] The imaging device 4 is installed, for example, in a server (not shown) installed in an external facility or a cloud environment, and reads out an image corresponding to the height position of the car 1 from the image group in the archiver 3, and transmits the image to the car 1 via the elevator control device 2. The imaging device 4 has a imaging mode setting unit 41, a imaging mode determination unit 42, a resolution setting unit 43, a download unit 44, a height position detection unit 45, a imaging range determination unit 46, and a imaging unit 47.

[0028] The depiction mode setting unit 41 sets various depiction modes to on (enabled) / off (disabled) based on various commands input from a mobile terminal or terminal device (not shown) by a building manager, maintenance manager, maintenance worker, etc., and on / off information of a switch (not shown), etc. Specifically, the depiction mode setting unit 41 switches on and off in each of the real-time live-action mode, maintenance mode, other position display mode, and archiver display mode.

[0029] The real-time live-action mode is a mode in which an image of the scenery outside the building, captured in real time by the building camera 5, is displayed on the car display 12. Based on the real-time live-action mode, an image actually captured outside the building in which the elevator is installed is displayed inside the car 1, allowing elevator users to view the scenery outside the window while inside the windowless car 1, which provides a refreshing effect to users.

[0030] The maintenance mode is a mode in which images of the status of various devices in the hoistway taken by the maintenance camera 6 are displayed on the car display 12. This mode is set when a maintenance worker is performing maintenance work. In the maintenance mode, the status of various devices in the hoistway can be confirmed from inside the car 1, allowing the maintenance worker to perform maintenance inspections safely without entering the hoistway.

[0031] The other position display mode is a mode in which images of the scenery of the tourist spot taken by a building camera or a drone installed in a building of the tourist spot (an example of a second building) are displayed on the car display 12. By displaying images taken at other positions inside the car 1 based on the other position display mode, elevator users can have a simulated experience of visiting a tourist spot while inside the car 1, which can be refreshing.

[0032] The archiver display mode is a mode in which an image of the scenery outside the building in which the elevator is installed, stored in the archiver 3, is displayed on the car display 12. By displaying an image of the scenery outside the building in which the elevator is installed inside the car 1 based on the archiver display mode, elevator users can get the feeling that they are looking at the scenery outside a window even while inside the windowless car 1, which provides a refreshing effect. An example of the procedure for the depiction mode setting process by the depiction mode setting unit 41 will be described in detail with reference to FIG. 9 below.

[0033] The depiction mode determination unit 42 determines whether each of the above-mentioned modes is enabled (whether it is set to ON). An example of the procedure for the depiction mode determination process by the depiction mode determination unit 42 will be described in detail later with reference to FIG.

[0034] The resolution setting unit 43 sets the resolution of the image to be extracted from the image group in the archiver 3 and displayed on the car interior display 12, based on information about the size and position of the display area of ​​the car interior display 12. Note that when an image is projected onto the wall surface of the car 1 using a projector or the like (not shown) provided inside the car 1, rather than the car interior display 12, the resolution setting unit 43 sets the resolution of the image to be displayed in the display area, based on information about the size and position of the display area (hereinafter also referred to as the depiction range) of the area where the image is projected (depicted). An example of the procedure for the resolution setting process by the resolution setting unit 43 will be described in detail with reference to Figures 4 and 5 described below.

[0035] The download unit 44 (an example of an image group acquisition unit) acquires (downloads) images corresponding to the mode set by the depiction mode setting unit 41 from the archiver 3, and stores the acquired images in a storage area (not shown) or the like. An example of the procedure for the image group acquisition process by the download unit 44 will be described in detail later with reference to FIG. 12.

[0036] The height position detection unit 45 (an example of a car height position information acquisition unit) acquires absolute position detection information of the car 1, i.e., information on the absolute height position of the car 1 in the hoistway, transmitted from the data output unit 22 of the elevator control device 2. The height position detection unit 45 also compensates (corrects) the acquired absolute position detection information of the car 1 with information on the height of the building. The height position information obtained by correction is output to the depiction range determination unit 46.

[0037] The depiction range determination unit 46 determines the depiction range of the video based on the height position information corrected by the height position detection unit 45. The height position detection process by the height position detection unit 45 and the depiction range determination process by the depiction range determination unit 46 will be outlined in detail with reference to Figs. 6 and 7, which will be described later, and an example of the procedure of each process will be described in detail with reference to Fig. 13, which will be described later.

[0038] The depiction unit 47 cuts out and extracts the image (image group) of the depiction range determined by the depiction range determination unit 46 from the image downloaded by the download unit 44, and transmits the extracted image group to the car interior display 12 of the car 1 via the elevator control device 2. An example of the procedure for the depiction processing by the depiction unit 47 will be described in detail later with reference to FIG. 13.

[0039] The camera image output unit 48 acquires images captured by the building camera 5 or the maintenance camera 6, transmits the images to the car 1 via the elevator control device 2, and displays them on the in-car display 12 or the wall of the car 1, etc.

[0040] <Example of computer hardware configuration> Next, the configuration (hardware configuration) of the control system of each device constituting the elevator system 100 shown in FIG. 1 will be described with reference to FIG.

[0041] Fig. 2 is a block diagram showing an example of the hardware configuration of each device that constitutes the elevator system 100. A calculator 200 shown in Fig. 2 is hardware used as a so-called computer.

[0042] The computer 200 includes a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, a non-volatile storage 204, and a communication I / F (Interface) 205, which are all connected to a bus B.

[0043] The CPU 201 reads out program code of software that realizes each function according to this embodiment from the ROM 202, expands it in the RAM 203, and executes it. Alternatively, the CPU 201 directly reads out the program code from the ROM 202 and executes it as is. Note that the computer 200 may include a processing device such as an MPU (Micro-Processing Unit) instead of the CPU 201. Variables, parameters, and the like that are generated during the arithmetic processing by the CPU 201 are temporarily written to the RAM 203.

[0044] The functions of the components constituting the imaging device 4 are realized by the CPU 201 reading out from the ROM 202 and executing a program for realizing each function.

[0045] The nonvolatile storage 204 may be, for example, a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a nonvolatile memory card, etc. In addition to an operating system (OS) and various parameters, programs for operating the computer 200 are also recorded in this nonvolatile storage 204. The function of the archiver 3 is realized by the nonvolatile storage 204.

[0046] The program may be stored in the ROM 202. The program is stored in the form of a computer-readable program code, and the CPU 201 sequentially executes operations in accordance with the program code. In other words, the ROM 202 or the non-volatile storage 204 is used as an example of a computer-readable non-transitory recording medium that stores a program to be executed by a computer.

[0047] The communication I / F 205 is configured by a communication device that controls communication between other devices. The network for which the communication I / F 205 controls communication includes, for example, a multi-drop serial communication such as RS-485, and a communication path that provides multiple topologies such as Ethernet (registered trademark). The communication path that provides multiple topologies includes a wired communication path such as a local area network (LAN) or a wide area network (WAN), and a wireless communication path such as a radio area network (RAN).

[0048] Furthermore, for example, networks for which communication I / F 205 performs communication control include wireless networks such as Wi-Fi (registered trademark) and wireless networks in wireless communication infrastructures. The functions of input / output information receiving unit 21 and data output unit 22 of elevator control device 2 are realized by communication I / F 205.

[0049] <Method of photographing the scenery outside the building and examples of images obtained by the photographing> Next, a method for photographing the scenery outside the building and an example of a group of images obtained by the photographing will be described with reference to Fig. 3. Fig. 3 is a diagram showing a method for photographing the scenery outside the building and an example of a group of images obtained by the photographing.

[0050] Fig. 3 shows a drone 7 capturing images of the scenery outside a building. The drone 7 captures images outside the building while moving, for example, from bottom to top in the direction indicated by the upward arrow in Fig. 3. Three vertically long rectangles indicated by dashed lines around the drone 7 represent image groups 101 to 103, respectively, generated based on the images captured by the drone 7.

[0051] Image groups 101 to 103 correspond to three sides of the building, respectively, and are vertically long image groups that include the entire landscape of the area from near the ground surface on each side to the top of the building. Areas 104 to 106 shown in color in FIG. 3 are areas photographed by drone 7, and information on the height position of drone 7 is associated with and stored as images of these photographed areas. In other words, image groups 101 to 103 are image groups that have height position information. When drone 7 photographs the area from the ground floor to the top floor of the building while changing the photographing height, each of image groups 101 to 103 has height position information that corresponds to the height from the ground floor to the top floor of the building (distance from the ground in the height direction).

[0052] While FIG. 3 shows an example in which the image group has a vertically elongated shape with a long side corresponding to the height of the building, the present invention is not limited to this. The image group may be composed of a plurality of captured images corresponding to the capture areas, such as capture areas 104 to 106. In this case, different height position information is associated with each of the plurality of captured images and stored. Furthermore, if the car 1 moves in a direction other than the vertical, an image group may be created according to the direction of movement of the object. In this case, the image group does not have a vertically elongated shape, but rather has images that are long in the direction of movement. In other words, the image group according to the present invention is intended to be images constructed by a configuration that can display external images within the range in which the car 1 can move.

[0053] 3 shows an example in which three image groups 101 to 103 corresponding to the three surfaces of the car 1 are generated, but the present invention is not limited to this. The image groups may be provided corresponding to the surfaces on which the car interior displays 12 that display images are provided, and the number of image groups may be one, two, or four.

[0054] <Resolution setting process by the resolution setting unit> Next, an overview of the resolution setting process performed by the resolution setting unit 43 (see FIG. 1) will be described with reference to FIGS.

[0055] Fig. 4 is a diagram showing size information of the target car display 12 (indicated as "target equipment" in the diagram) on which an image from the image group is displayed, and Fig. 4 shows that the horizontal (X) size of the car display 12 is "X0" and the vertical (Y) size is "Y0". The resolution setting unit 43 sets (defines) the resolution of the extraction range when extracting an image of an area corresponding to the size of the car display 12 from the image group. The resolution setting unit 43 sets the width in the X and Y directions and the coordinate axes as the resolution.

[0056] 3, for example, if the images of the entire region of the image group 102 were reduced to fit the size of the car interior display 12 and displayed, the aspect ratio of the image displayed on the car interior display 12 would change, resulting in image distortion. In order to prevent such distortion from occurring, the resolution setting unit 43 sets a resolution that can reproduce as faithfully as possible the aspect ratio and scale of the scenery outside the building that can be seen through the car interior display 12 when the car interior display 12 is viewed as a window.

[0057] Fig. 5 is a diagram showing information about the sizes of two wall surfaces inside car 1 when the target on which the image is to be displayed is a wall surface inside car 1. Fig. 5 shows that the horizontal (X) size of wall surface 16a (indicated as "target facility (1)" in the figure) onto which the image is projected by projector 15a is "X1" and the vertical (Y) size is "Y1". It also shows that the horizontal (X) size of wall surface 16b (indicated as "target facility (2)" in the figure) onto which the image is projected by projector 15b is "X2" and the vertical (Y) size is "Y2".

[0058] Even when the object on which the image is displayed is a wall surface inside the car 1, the resolution setting unit 43 sets the resolution of the extraction (depiction) range as a parameter when extracting an image from the image group and displaying (depicting) it on the target equipment based on the size of the display area of ​​the image.

[0059] <Rendering range determination process by rendering range determination unit> Next, an outline of the depiction range determination process performed by the depiction range determination unit 46 (see FIG. 1) will be described with reference to FIGS.

[0060] Figure 6 is a diagram showing an overview of the depiction range determination process when the object on which the image is displayed is the car interior display 12, and Figure 7 is a diagram showing an overview of the depiction range determination process when the object on which the image is displayed is the wall surface of car 1.

[0061] The left side of FIG. 6 shows a vertically elongated image group 101 to an image group 103, and the right side of FIG. 6 shows a car 1 located at a certain height position. The depiction range determination unit 46 determines a height position H1 in the image group of an extraction (depicting) range to be extracted from the image group (depicted on the target equipment) based on the absolute position detection information of the car 1 received by the height position detection unit 45 from the elevator control device 2. More specifically, the depiction range determination unit 46 determines a height position H1 of the depiction range in the image group based on a height position obtained by supplementing (correcting) the height position of the building to the height position of the car 1 indicated in the absolute position detection information. The height position H1 is the height from the bottom edge to the center of the depiction range 110, which will be described later. An example of the correction of the height position based on the building height position will be described in detail with reference to FIG. 8, which will be described later.

[0062] The depiction range determination unit 46 determines the depiction range 110 of the image on the car interior display 12 based on the height position and the resolution information set by the resolution setting unit 43. The depiction unit 47 then extracts images in the depiction range 110 determined by the depiction range determination unit 46 from the group of images downloaded by the downloading unit 44. The depiction unit 47 then transmits the extracted images to the car interior display 12 of the car 1 via the elevator control device 2 for display. By performing such processing by the depiction range determination unit 46 and the downloading unit 44, the amount of data of the group of images downloaded from the archiver 3 can be reduced.

[0063] 7 shows an example of the depiction range when the image display target is the wall surface of car 1 and there are two display surfaces. In this case, the depiction range determination unit 46 determines the depiction range 111 to the depiction range 112 of the image for each of the image group 101 corresponding to the first surface of car 1 and the image group 102 corresponding to the second surface, based on the height position H2 corresponding to the absolute position detection information of car 1.

[0064] Next, an example of correction of the absolute position of the car 1 by the height position detection unit 45 will be described with reference to Fig. 8. Fig. 8 is a diagram showing the correspondence between the absolute position of the car 1, the height position of the building, and the height positions of the image group.

[0065] Figure 8 shows an example in which an elevator 10a for an upper bank and a shuttle elevator 10b that transports passengers to the departure floor of elevator 10a are installed in building B. The ascending and descending range of shuttle elevator 10b is from the first basement floor to the departure floor of elevator 10a, and the height of this ascending and descending range is assumed to be "210 (m)." In this case, "0," which is the lower limit of the absolute position of shuttle elevator 10b, corresponds to the height position of the first basement floor, and "210," which is the upper limit of the absolute position, corresponds to the height position of (the ceiling position of) the departure floor of elevator 10a.

[0066] The lifting range of elevator 10a is from the departure floor to the top floor of building B, and the height of this lifting range is "100 (m)." In this case, "0," which is the lower limit of the absolute position of elevator 10a, corresponds to the height position of the departure floor of elevator 10a, and "100," which is the upper limit of the absolute position, corresponds to the height position of the top floor (ceiling position) of elevator 10a.

[0067] On the other hand, the height position "0" of building B corresponds to the height position of the bottom of building B, which is in the basement, and the height position "300" corresponds to (the ceiling position of) the top floor. Since image group 101 is a photograph of the scenery ranging from the ground to the top floor of building B, the lower limit value of the height position "0" corresponds to the height position of the ground floor, and the upper limit value "280" corresponds to the height position of (the ceiling position of) the top floor of building B. The actual height position of the top floor of building B is "300", but this value is the value when the bottom of building B is used as the starting point, so "280" when the ground floor is used as the starting point is the upper limit value of the height position of image group 101.

[0068] For example, assume that the image display target is the upper bank elevator 10a. In this case, the height position detection unit 45 compensates for the absolute position "0" detected by the elevator 10a with "200," which is the height position of building B. Then, the depiction range determination unit 46 sets the height position "180" in the image group 101 linked to the compensated "200" as the height position of the depiction range of the image.

[0069] By performing such processing by the height position detection unit 45 and the depiction range determination unit 46, it becomes possible to display, inside the car 1, a scenic image of the outside of the building B that corresponds to the height position of the car 1 within the building B, without having to prepare in advance multiple images that correspond to the running pattern, etc. Furthermore, no matter what height position the elevator is installed at, it becomes possible to display, inside the car 1, a scenic image of the outside of the building that corresponds to the height position of the car 1.

[0070] In an elevator in which the height position information of the lifting range of car 1 corresponds to the height position information of building B, the depiction range determination unit 46 may determine the height position in the depiction range image group of the image based on the absolute position detection information, without making correction based on the height position of building B. Alternatively, the user may set an arbitrary correction position and set a desired position as the ground floor.

[0071] <Drawing mode setting process by the drawing mode setting unit> Next, the depiction mode setting process performed by the depiction mode setting unit 41 will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the procedure for the depiction mode setting process performed by the depiction mode setting unit 41.

[0072] First, the depiction mode setting unit 41 determines whether the setting of the device for setting the maintenance mode is enabled (step S1). The device for setting the maintenance mode may be, for example, a button or a switch. Instead of switching between enabled (ON) and disabled (OFF) on such a device, the activation of the maintenance mode may be instructed by a command from an external device (not shown), a trigger input based on a schedule, or the like.

[0073] If it is determined in step S1 that the setting of the device for setting the maintenance mode is valid (if step S1 is judged as YES), the depiction mode setting unit 41 enables the setting of the maintenance mode (step S2). On the other hand, if it is determined in step S1 that the setting of the device for setting the maintenance mode is invalid (if step S1 is judged as NO), the depiction mode setting unit 41 determines whether the setting of the device for setting the real-time live-action mode is valid (step S3).

[0074] Like the device for setting the maintenance mode, the device for setting the real-time live-action mode is configured with, for example, a button, a switch, etc. Alternatively, activation of the real-time live-action mode may be instructed by a command from an external device, a trigger input based on a schedule, or the like.

[0075] If it is determined in step S3 that the device setting for setting the real-time live-action mode is valid (if step S3 is judged as YES), the depiction mode setting unit 41 enables the setting of the real-time live-action mode (step S4). On the other hand, if it is determined in step S3 that the device setting for setting the real-time live-action mode is invalid (if step S3 is judged as NO), the depiction mode setting unit 41 determines whether or not the other position display service is available (step S5).

[0076] The availability / inability of the other position display service may be switched based on the operation of a button, switch, etc., or based on a command, trigger, etc. If it is determined in step S5 that the other position display service is available (if step S5 returns YES), the depiction mode setting unit 41 enables the setting of the other position display mode (step S6).

[0077] On the other hand, if it is determined in step S5 that the use of other location display services is not possible (if step S5 is determined as NO), the depiction mode setting unit 41 determines whether or not connection to the archiver 3 is possible (step S7). If a service is provided by the archiver 3 and communication with the archiver 3 is possible, step S7 is determined as YES. On the other hand, if a service is not provided by the archiver 3 or if communication with the archiver 3 cannot be performed due to a communication failure or the like, step S7 is determined as NO.

[0078] If the determination in step S7 is YES, the depiction mode setting unit 41 enables the setting of the archiver display mode (step S8). After the processing of step S8, or if the determination in step S7 is NO, the depiction mode setting process by the depiction mode setting unit 41 ends.

[0079] <Rendering mode determination process by the rendering mode determination unit> Next, the depiction mode determination process performed by the depiction mode determination section 42 will be described with reference to Fig. 10. Fig. 10 is a flowchart showing an example of the procedure for the depiction mode determination process performed by the depiction mode determination section 42.

[0080] First, the depiction mode determination unit 42 determines whether or not the maintenance mode setting is enabled (step S11). If it is determined in step S11 that the maintenance mode setting is enabled (if the determination in step S11 is YES), the depiction mode determination unit 42 determines whether or not a transition to the maintenance mode has occurred (step S12). If it is determined in step S12 that a transition to the maintenance mode has occurred (if the determination in step S12 is YES), the depiction mode determination unit 42 determines that the depiction mode is the maintenance mode (step S13). If it is determined that the depiction mode is the maintenance mode, the image captured by the maintenance camera 6, acquired by the camera image output unit 48, is displayed on the car interior display 12, the wall surface of the car 1, or the like.

[0081] If the determination in step S11 is NO or if the determination in step S12 is NO, the depiction mode determination unit 42 determines whether the real-time live-action mode setting is enabled (step S14). If the determination in step S14 is that the real-time live-action mode setting is enabled (if the determination in step S14 is YES), the depiction mode determination unit 42 determines whether a transition to the real-time live-action mode has been made (step S15).

[0082] If it is determined in step S15 that the mode has been switched to real-time live-action mode (if step S15 is determined to be YES), the depiction mode determination unit 42 determines that the depiction mode is the real-time live-action mode (step S16). If it is determined that the depiction mode is the real-time live-action mode, the image captured by the building camera 5 and acquired by the camera image output unit 48 is displayed on the car interior display 12 or the wall surface of the car 1, etc.

[0083] If the determination in step S14 is NO or if the determination in step S15 is NO, the depiction mode determination unit 42 determines whether the other position display mode setting is enabled (step S17). If the determination in step S17 is that the other position display mode setting is enabled (if the determination in step S17 is YES), the depiction mode determination unit 42 determines whether a transition to the other position display mode has been made (step S18).

[0084] If it is determined in step S18 that the mode has been switched to the other position display mode (if step S18 is determined to be YES), the depiction mode determination unit 42 determines that the depiction mode is the other position display mode (step S19). If it is determined that the depiction mode is the other position display mode, the captured image of the other position acquired from the server or archiver 3 (not shown) or the like is displayed on the car interior display 12 or the wall surface of the car 1 or the like.

[0085] If the determination in step S17 is NO or if the determination in step S18 is NO, the depiction mode determination unit 42 determines whether the archiver display mode setting is enabled (step S20). If the determination in step S20 is that the archiver display mode setting is enabled (if the determination in step S20 is YES), the depiction mode determination unit 42 determines whether a transition to the archiver display mode has been made (step S21).

[0086] If it is determined in step S21 that the mode has been switched to the archiver display mode (if step S21 is determined as YES), the depiction mode determination unit 42 determines that the depiction mode is the archiver display mode (step S22). If it is determined that the mode is the archiver display mode, the video of the image group 33 acquired from the archiver 3 or the like is displayed on the car interior display 12 or the wall surface of the car 1 or the like.

[0087] If the determination in step S20 is NO, or if the determination in step S21 is NO, the depiction mode determination unit 42 determines that no mode is set and that the archiver 3 cannot be used (step S23). After the processing of step S13, step S16, step S19, step S22, or step S23, the depiction mode setting processing by the depiction mode determination unit 42 ends.

[0088] <Resolution setting process by the resolution setting unit> Next, the resolution setting process by the resolution setting unit 43 will be described with reference to Fig. 11. Fig. 11 is a flowchart showing an example of the procedure for the resolution setting process by the resolution setting unit 43.

[0089] First, the resolution setting unit 43 determines whether the number of display screens for images in the car 1 is other than one (step S31). If it is determined in step S31 that the number of display screens is other than one, that is, two or more (if the determination in step S31 is YES), the resolution setting unit 43 sets information on the number of display screens as a parameter (step S32).

[0090] Next, the resolution setting unit 43 sets the size of each target equipment corresponding to each number of faces (step S33). The target equipment includes, for example, the car interior display 12 and the display area on the wall surface inside the car 1. Next, the resolution setting unit 43 sets the resolution of each depiction range of the image when the image is extracted from the image group and displayed on the target equipment (step S34).

[0091] On the other hand, if it is determined in step S31 that the number of display screens for images in car 1 is one (if step S31 is determined to be NO), the resolution setting unit 43 sets the size of the target equipment present on that screen (step S35). Next, the resolution setting unit 43 sets the resolution of the depiction range of the image (step S36). After processing step S34 or step S36, the resolution setting process by the resolution setting unit 43 ends.

[0092] <Download processing by the download section> Next, the download process by the download unit 44 will be described with reference to Fig. 12. Fig. 12 is a flowchart showing an example of the procedure of the download process by the download unit 44.

[0093] First, the download unit 44 determines whether the set mode is the other position display mode (step S41). If it is determined in step S41 that the other position display mode is set (if the determination in step S41 is YES), the download unit 44 extracts from the archiver 3 video of another position with a display time corresponding to the current time (step S42). Note that the current time and the display time do not need to correspond strictly, and the download unit 44 can extract morning video if the current time is in the morning, daytime video if the current time is around noon, etc.

[0094] Next, the download unit 44 determines the location (area, direction, etc.) to be displayed on the target facility in the video captured at another position (step S43). The location may be determined based on a predetermined setting value, etc., or may be determined based on the content of an operation input by an elevator user, etc. Next, the download unit 44 downloads the image group (data) corresponding to the display position from the archiver 3 at the resolution set by the resolution setting unit 43 (step S44).

[0095] On the other hand, if it is determined in step S41 that the mode is not the other position display mode (if step S41 is determined as NO), the download unit 44 determines whether the mode is the archiver display mode (step S45).If it is determined in step S45 that the mode is the archiver display mode (if step S45 is determined as YES), the download unit 44 extracts video captured at another position at the display time corresponding to the current time (step S46).

[0096] Next, the download unit 44 extracts a group of images (data) for a time period (period, era, etc.) to be downloaded (step S47). Next, the download unit 44 downloads the group of images (data) from the archiver 3 at the resolution set by the resolution setting unit 43 (step S48).

[0097] On the other hand, if it is determined in step S45 that the archiver display mode is not active (if step S45 is determined to be NO), the download unit 44 clears any downloaded data (step S49). Thereafter, the rendering unit 47 performs control to display (render) on the target equipment the image stored in the ROM 202 (see FIG. 2) or the like in the rendering device 4. After the processing of step S44, step S48, or step S49, the download processing by the download unit 44 ends.

[0098] <Processing by the height position detection unit, depiction range determination unit, and depiction unit> Next, the processing by the height position detection unit 45, the depiction range determination unit 46, and the depiction unit 47 will be described with reference to Fig. 13. Fig. 13 is a flowchart showing an example of the procedure for the height position detection processing by the height position detection unit 45, the depiction range determination processing by the depiction range determination unit 46, and the depiction processing by the depiction unit 47.

[0099] First, the height position detection unit 45 receives the absolute position detection information of the car 1 transmitted from the elevator control device 2 (step S51). Next, the height position detection unit 45 corrects the information on the height position of the car 1 to match the height of the building B (step S52). In other words, the height position detection unit 45 sets the height position of the car 1 to the height position indicated in the absolute position detection information of the car 1, compensated for by the height position of the building B.

[0100] Next, the depiction range determination unit 46 determines the depiction range based on the information on the height position of the car 1 corrected in step S52 (step S53).

[0101] Next, the depiction unit 47 determines whether or not there is download data that has been downloaded by the download unit 44 (step S54). If it is determined in step S54 that there is download data (if the determination in step S54 is YES), the depiction unit 47 extracts an image (data) corresponding to the depiction range from the download data (step S55). Next, the depiction unit 47 transmits the extracted data to the car display 12 (or a projector, etc.) via the elevator control device 2 (step S56).

[0102] On the other hand, if it is determined in step S54 that there is no download data (if step S54 is determined to be NO), an image corresponding to the depiction range is extracted from data stored in ROM 202 (see FIG. 2) or the like (step S57). Next, the depiction unit 47 performs the process of step S56. That is, the extracted image (data) is transmitted to the car interior display 12 (or a projector, etc.) via the elevator control device 2. After the process of step S56, the depiction process by the depiction unit 47 ends.

[0103] When an image group is read based on the process shown in Fig. 13, the frame rate for reading (rendering) the image is preferably set to a rate corresponding to the rated speed of the elevator. If the rated speed of the elevator is relatively high, even if the frame rate is low, dropped frames are unlikely to occur in the displayed image. On the other hand, if the rated speed is constant, a low frame rate may result in the image being displayed frame by frame on the target equipment.

[0104] For example, when the vertically elongated image groups 101 to 103 shown in Fig. 3 are to be depicted, the frame rate can be adjusted by changing the interval (the distance in the height direction) at which height position information is assigned to the image groups. Also, when the image groups are made up of a collection of images corresponding to the shooting area 104 shown in Fig. 3, the frame rate can be adjusted by changing the number of images associated with height positions (the distance between the height positions associated with each of the multiple images). Then, by setting the frame rate for depicting the video to an optimal rate according to the rated speed of the elevator, it is possible to prevent dropped frames and the like from occurring in the video depicted on the target equipment inside car 1.

[0105] The elevator system 100 according to the embodiment described above is an elevator system that displays an image of the outside of the elevator car 1 or the outside of the building B in which the elevator is installed in a display area (target equipment) within the elevator car 1. The elevator system 100 has a height position detection unit 45 that acquires absolute position detection information that indicates the absolute position of the car 1 in the height direction within the hoistway, and a depiction unit 47 that extracts from the archiver 3 a group of images having height position information that corresponds to the absolute position detection information of the car acquired by the height position detection unit 45, and displays the images in the display area within the car 1.

[0106] Therefore, according to the above-described embodiment, it is possible to display an image of the outside of building B in which the elevator is installed in the display area inside car 1 in conjunction with the ascending and descending movement of car 1, without having to prepare images for each travel pattern in advance. This allows elevator users to see the scenery outside building B while riding in car 1, making it possible for users to refresh themselves even in confined situations where measures to prevent infectious diseases are necessary.

[0107] <Variation 1> In the above-described embodiment, an example has been given in which the position detector 14 (see FIG. 1) is capable of detecting the absolute position of the car 1, but the present invention is not limited to this. The absolute position (height position) of the car 1 may be calculated based on position correction information, position information estimated based on information on the passage of time, etc.

[0108] Fig. 14 is a diagram showing a schematic configuration example of an elevator system 100A according to Modification 1. The elevator system 100A shown in Fig. 14 differs from the elevator system 100 shown in Fig. 1 in that the elevator control device 2A includes an absolute position calculation unit 23. The other configurations are the same as those of the elevator system 100, so redundant explanations will be omitted.

[0109] FIG. 15 is a flowchart showing an example of the procedure of the absolute position calculation process by the absolute position calculation unit 23 of the elevator system 100A according to the first modification.

[0110] First, the absolute position calculation unit 23 determines whether or not there is position correction information (step S61). The position correction information is composed of a correction value calculated based on information about the difference between the position of the car 1 detected by the position detector 14A and the actual position of the car 1.

[0111] The position detector 14A in the first modification detects the position of the car 1 in the elevator shaft based on, for example, the number of rotations of the motor (not shown) of the hoisting machine from the time of departure from the ground floor. The actual height position of the car 1 is acquired based on the detection result of the position of a hole in a shielding plate (not shown) in the elevator shaft by an optical sensor (not shown) provided on the outside of the car 1.

[0112] If it is determined in step S61 that there is position correction information (if step S61 is determined as YES), the absolute position calculation unit 23 executes position correction (correction of the height position of the car 1) using the position correction information (step S62). Next, the absolute position calculation unit 23 outputs the information on the position corrected in step S62 as car absolute position information (step S63).

[0113] On the other hand, if it is determined in step S61 that there is no position correction information (if step S61 is determined to be NO), the absolute position calculation unit 23 extracts the time at the previous stopping position of car 1 or the number of clocks of the running pulse of car 1 (step S64).

[0114] Next, the absolute position calculation unit 23 calculates the distance traveled by the car 1 based on the time at the previous stop position extracted in step S64 or the number of clocks of the traveling pulses, and estimates the current position of the car 1 based on the distance traveled (step S65). Next, the absolute position calculation unit 23 performs the processing of step S63. That is, the absolute position calculation unit 23 outputs information on the current position of the car 1 estimated in step S65 as absolute position information of the car 1. After the processing of step S63, the absolute value calculation processing by the absolute position calculation unit 23 ends.

[0115] According to the first modification, even in an elevator system that does not have a device for detecting the absolute position of the car 1, it is possible to obtain the same effects as those obtained by the above-described embodiment.

[0116] <Variation 2> Next, an elevator system 100B according to a second modification of the present invention and a display control method by the elevator system 100B will be described with reference to Figures 16 to 18. The elevator system 100B according to the second modification displays information about the surroundings of the building B that has been prepared in advance, along with the video (image group) read out from the archiver 3 according to the height position of the car 1.

[0117] Fig. 16 is a diagram showing a schematic configuration example of an elevator system 100B according to Modification 2. The elevator system 100B shown in Fig. 16 differs from the elevator system 100 shown in Fig. 1 in that peripheral information 35 is stored in an archiver 3A and that the depiction device 4A is equipped with a peripheral information output unit 49. The other configurations are the same as those of the elevator system 100, so redundant explanations will be omitted.

[0118] The surrounding information 35 is information that stores coordinate position information, name information, and image outline information (exterior frame) information of various facilities such as tourist spots, restaurants, and shops around the building B. Note that the surrounding information 35 may also include information other than the above.

[0119] The peripheral information output unit 49 reads out the corresponding peripheral information 35 from the archiver 3A based on information about the depiction range of the image determined according to the height position of the car 1, and outputs it to the depiction unit 47. Then, the depiction unit 47 displays the peripheral information input from the peripheral information output unit 49 in the car 1 by superimposing it on the image read out from the archiver 3A.

[0120] 17 is a flowchart showing an example of the procedure of a peripheral information output process by the peripheral information output unit 49. First, the peripheral information output unit 49 determines whether or not peripheral information 35 is registered in the archiver 3A (step S71). If it is determined in step S71 that peripheral information 35 is registered (if the determination in step S71 is YES), the peripheral information output unit 49 acquires information on the depiction position (range) of the image and peripheral information 35 that can be displayed (step S72). The peripheral information 35 that can be displayed includes peripheral information within a distance range from building B that is determined as a preset value, peripheral information within a range that can be seen as an image, etc.

[0121] Next, the peripheral information output unit 49 identifies the position (coordinates) of the image corresponding to the depiction range in the peripheral information 35 (step S73). Next, based on the position information identified in step S73, the peripheral information output unit 49 associates the normal image (image read from the archiver 3A) with the image of the peripheral information (peripheral image), and outputs them to the depiction unit 47 (step S74).

[0122] On the other hand, if it is determined in step S71 that the peripheral information is not registered (if step S71 is determined as NO), the peripheral information output unit 49 reads out the normal image from the archiver 3A and outputs it to the depiction unit 47 (step S75). After the processing of step S74 or step S75, the peripheral information output processing by the peripheral information output unit 49 ends.

[0123] Fig. 18 is a diagram showing an example of an image in which surrounding information is superimposed. Fig. 18 shows surrounding information superimposed on an image of the scenery visible from building B. In the example shown in Fig. 18, the text in the speech bubble clearly indicates that there are "tourist spot A," "tenants B and C," "restaurants B and C," etc., in the vicinity of building B.

[0124] According to the second modification, elevator users can check information such as the names and locations of facilities around building B while riding in car 1.

[0125] <Variation 3> Next, an elevator system 100C according to Modification 3 of the present invention and a display control method by the elevator system 100C will be described with reference to Figures 19 and 20. The elevator system 100C according to Modification 3 displays information about the surroundings of building B (peripheral information 35) superimposed on an image actually captured by the building camera 5.

[0126] Fig. 19 is a diagram showing a schematic configuration example of an elevator system 100C according to Modification 3. The elevator system 100C shown in Fig. 19 differs from the elevator system 100B shown in Fig. 16 in that the archiver 3B includes only an ID 31 and peripheral information 35, and the depiction device 4B includes only a depiction range determination unit 46, a peripheral information output unit 49A, and a depiction unit 47. The other configurations are the same as those of the elevator system 100B, and therefore redundant explanations will be omitted.

[0127] Fig. 20 is a flowchart showing an example of the procedure for peripheral information output processing by peripheral information output unit 49 A. Steps S81 and S82 in Fig. 20 are the same as steps S71 and S72 in Fig. 17, respectively, and therefore description thereof will be omitted.

[0128] In step S83, the peripheral information output unit 49A identifies the position of the peripheral information in the depiction range. In Modification 3, the depiction device 4B does not read out an image from the archiver 3B, but superimposes the peripheral information 35 on the video captured in real time by the building camera 5. Therefore, the peripheral information output unit 49A associates the captured video with the peripheral information by matching the video captured by the building camera 5 with the peripheral information by pattern matching.

[0129] After the process of step S83, the peripheral information output unit 49A outputs an image of the peripheral information associated with the video to the depiction unit 47 (step S84). After the process of step S84, the peripheral information output process by the peripheral information output unit 49A ends.

[0130] According to the third modification, elevator users can check the surrounding information displayed superimposed on the actual scenery seen from building B, thereby obtaining the surrounding information more accurately.

[0131] <Other variations> Furthermore, in the above-described embodiment and various modified examples, an example was given in which an image having height position information corresponding to the height position of car 1 is displayed in the display area inside car 1. However, the present invention is not limited to this. For example, in shuttle elevator 10b shown in FIG. 8, a group of images having height position information of upper bank elevator 10a may be displayed. Such control can be realized, for example, by receiving input from elevator passengers via in-car display 12 or a mobile terminal (not shown) of height position information (or information on buildings or scenery associated with the height position information) of the video they wish to view (display in car 1). This control allows elevator passengers to view video from their preferred height position from inside car 1. For example, while riding in a low-rise elevator, passengers can virtually enjoy the view from a high-rise elevator, providing a highly refreshing experience.

[0132] It is also easy to imagine changing the configuration so that the car 1 can display an image according to the direction of movement of the object. In this case, it is necessary to prepare a group of images according to the distance with respect to the direction of movement. Furthermore, although the above-described embodiment and each modified example describe correction of the height position, the present invention can also be applied to a car that moves in a direction other than horizontal by setting an arbitrary position as the start position of the car's movement.

[0133] Furthermore, the above-described embodiments and variations provide detailed and specific descriptions of the configurations of the devices and systems in order to clearly explain the present invention, and are not necessarily limited to those having all of the configurations described.

[0134] 1, 14, 16, and 19, the control lines or information lines indicated by solid lines or single arrows are those considered necessary for explanation, and do not necessarily show all control lines or information lines in the product. In reality, it can be considered that almost all components are interconnected.

[0135] Furthermore, in this specification, processing steps describing chronological processing include not only processing that is performed chronologically in the order described, but also processing that is not necessarily performed chronologically but is performed in parallel or individually (for example, parallel processing or processing by objects).

[0136] Furthermore, each component of the elevator system according to the embodiment or each modification of the present invention described above may be implemented in any hardware as long as the respective hardware can transmit and receive information to each other via a network. Furthermore, the processing performed by a certain processing unit may be realized by a single piece of hardware, or may be realized by distributed processing using multiple pieces of hardware.
