Detailed Implementation

[0035] The following description, with reference to the accompanying drawings, illustrates examples of methods for carrying out the present invention (hereinafter referred to as "implementations"). The present invention is not limited to these embodiments; the various numerical values, etc., in the embodiments are merely illustrative. Furthermore, in this specification and the accompanying drawings, the same reference numerals are used to denote the same constituent elements or constituent elements that substantially have the same function, and repeated descriptions are omitted.

[0036] <Overall Structure of Elevator System>

[0037] First, refer to Figure 1 The structure of an elevator system 100 according to one embodiment of the present invention will be described below. Figure 1 This is a diagram showing a schematic structural example of an elevator system 100.

[0038] like Figure 1 As shown, the elevator system 100 (an example of an elevator display control system) includes a car 1, an elevator control device 2, a data storage unit 3, and a display device 4. The car 1, elevator control device 2, data storage unit 3, and display device 4 are interconnected via a network N.

[0039] [Elevator Car]

[0040] The car 1 carries passengers or cargo (not shown) and moves up and down within a lift channel (not shown). The car 1 includes a speaker 11, an in-car display 12, a camera 13, and a position detector 14.

[0041] The speaker 11 plays a given broadcast or similar program based on the control of the elevator control device 2.

[0042] The in-car display 12 is a display device composed of a liquid crystal panel or an organic electroluminescent panel, etc., which displays the destination floor, arrows indicating the direction of lifting, etc. In addition, the in-car display 12 displays a group of images transmitted from the drawing device 4, images captured by the building camera 5, or images captured by various devices in the lifting channel of the maintenance camera 6.

[0043] Camera 13 captures images of the interior of the elevator car 1 and generates an image signal, which is then sent to the elevator control device 2.

[0044] A position detector 14 is installed on the upper or lower part of the outer side of the car 1 to detect the absolute position of the car 1 within the elevator shaft. The position detector 14 detects the current height position of the car 1 within the elevator shaft, the floor where it is stopped, etc., based on information such as the absolute position (e.g., the height from the bottom of the elevator shaft) detected by a magnetic sensor (not shown) that reads a magnetic tape installed within the elevator shaft, or a photoelectric sensor that detects the position of a hole in a shield (not shown) installed within the elevator shaft, and initial values. The position detector 14 sends the detected height position information of the car 1 (hereinafter also referred to as absolute position detection information) to the elevator control device 2.

[0045] The elevator control device 2 is located in the elevator machine room, elevator shaft, or other area not shown in the diagram, and controls the movement of the car 1. The elevator control device 2 includes an input / output information receiving unit 21 and a data output unit 22.

[0046] The input / output information receiving unit 21 receives the absolute position detection information of the car 1 sent from the car 1 and outputs it to the data output unit 22. It also receives the image group sent from the drawing 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, images captured by various devices in the lifting channel of the maintenance camera 6, etc., and outputs them to the data output unit 22.

[0047] The data output unit 22 sends the absolute position detection information of the car 1 input from the input / output information receiving unit 21 to the drawing device 4, or sends the image group or various captured images input from the input / output information receiving unit 21 to the car display 12 inside the car 1. Furthermore, in this embodiment, illustrations of the functional units in the elevator control device 2 that control the movement of the car 1 are omitted.

[0048] The building camera 5 is configured, for example, to capture images of the exterior of the building, such as the outside of the elevator car 1, and to capture the scenery outside the building. In cases where the elevator shaft is covered by glass, or when the invention is applied to an externally exposed observation elevator, it is envisioned that the building camera 5 be installed directly in the elevator car.

[0049] Alternatively, the building camera 5 may have a lifting mechanism that is independently installed on the wall of the building and moves in sync with the lifting action of the car 1, or it may consist of multiple cameras installed at multiple height positions.

[0050] The maintenance camera 6 is installed, for example, on the outside of the car 1, and while it is raised and lowered in conjunction with the lifting action of the car 1, it captures the status of various devices in the lifting channel.

[0051] The archive unit 3 (an example of a storage unit) is installed, for example, in an external device or in a server (not shown) in a cloud environment, and stores various types of data. The archive unit 3 includes a data management unit 30, which stores information such as ID 31, location information 32, image group 33, and height information 34.

[0052] ID31 represents the ID identifying the building equipped with an elevator. Location information 32 represents the building's location information, such as GPS (Global Positioning System) location information.

[0053] Image group 33 consists of images of scenery outside buildings taken by drones (not shown), other cameras (not shown), and scenery of tourist attractions (an example of another location). Image group 33 may include, for example, images corresponding to different time periods such as morning, daytime, and nighttime, as well as images taken within multiple different timeframes (periods, years). See below for further details. Figure 3 This illustrates a method for photographing scenery outside buildings and provides examples of the resulting image sets.

[0054] Height information 34 is information representing the physical height of a building.

[0055] The drawing device 4, for example, is installed in an external device or a server (not shown) in a cloud environment, and reads the image corresponding to the position of the car 1 in the height direction from the image group of the storage unit 3, and sends the image to the car 1 via the elevator control device 2. The drawing device 4 includes a drawing mode setting unit 41, a drawing mode determination unit 42, a resolution setting unit 43, a download unit 44, a height position detection unit 45, a drawing range determination unit 46, and a drawing unit 47.

[0056] The drawing mode setting unit 41 sets the ON (enabled) / OFF (disabled) of various drawing modes based on various commands input by building managers, maintenance managers, maintenance workers, etc. (from portable terminals or terminal devices not shown), and on / off information such as switches not shown). Specifically, the drawing mode setting unit 41 switches between enabled and disabled modes in each of the following modes: real-time shooting mode, maintenance mode, other location display mode, and archive display mode.

[0057] The real-time shooting mode displays images of the scenery outside the building captured in real-time by the building camera 5 on the in-car display 12. By displaying actual images of the exterior of the building with the elevator inside the car 1 based on the real-time shooting mode, elevator users can enjoy the scenery outside the window even while inside the windowless car 1, thus achieving a mental relaxation effect.

[0058] The maintenance mode is a mode in which the display screen 12 inside the car shows images of the status of various devices in the elevator shaft captured by the maintenance camera 6. This mode is set when maintenance personnel are performing maintenance work. In maintenance mode, since the status of various devices in the elevator shaft can be checked inside the car 1, maintenance personnel can perform maintenance and repairs safely without entering the elevator shaft.

[0059] Other location display mode is a mode in which the display screen 12 in the elevator car shows images of the scenery of the tourist attraction captured by building cameras, drones, etc., located in the building (an example of the second building). By displaying images captured from other locations in the elevator car 1 based on other location display mode, elevator users can have a virtual experience of touring the tourist attraction while staying in the elevator car 1, thus seeking mental relaxation.

[0060] The archive display mode displays images of the scenery outside the building equipped with the elevator, stored in the archive section 3, on the in-car display 12. By displaying these images of the scenery outside the building equipped with the elevator inside the car 1 based on the archive display mode, elevator users can experience the feeling of looking out at a view from inside the windowless car 1, thus achieving a relaxing effect. (See description below.) Figure 9 Here is an example of the process of setting the drawing mode in the drawing mode setting unit 41.

[0061] The drawing mode determination unit 42 determines whether each of the above-mentioned modes is valid (whether it is set to ON). (Refer to the following description.) Figure 10 Here is an example of the process of rendering mode determination in rendering mode determination unit 42.

[0062] The resolution setting unit 43 sets the resolution of the image extracted from the image group in the archive unit 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. Furthermore, when the image is projected onto the wall of the car 1 using a projector (not shown) installed in the car 1 instead of the car interior display 12, the resolution setting unit 43 sets the resolution of the image displayed in that display area based on information about the size and position of the display area (hereinafter also referred to as the drawing area) of the area where the image is projected (drawn). (Refer to the following description.) Figure 4 as well as Figure 5 Here is an example of the resolution setting process of the resolution setting unit 43.

[0063] The download unit 44 (an example of an image group acquisition unit) acquires (downloads) an image corresponding to the mode set by the drawing mode setting unit 41 from the archive unit 3, and stores the acquired image in a storage area (not shown). See below for further details. Figure 12Here is an example detailing the process of acquiring and processing images in the download section 44.

[0064] The height position detection unit 45 (an example of a car height position information acquisition unit) acquires the absolute position detection information of the car 1 sent from the data output unit 22 of the elevator control device 2, that is, the absolute position information of the height of the car 1 within the elevator shaft. Furthermore, the height position detection unit 45 compensates (corrects) the acquired absolute position detection information of the car 1 using information about the building's height. The corrected height position information is then output to the drawing range determination unit 46.

[0065] The depiction range determination unit 46 determines the depiction range of the image based on the corrected height position information in the height position detection unit 45. (See below for further details.) Figure 6 as well as Figure 7 For a detailed overview of the height position detection processing of the height position detection unit 45 and the drawing range determination processing of the drawing range determination unit 46, please refer to the following description. Figure 13 Here are examples detailing the processes involved in each step.

[0066] The drawing unit 47 crops and extracts images (image groups) within the drawing range determined by the drawing range determination unit 46 from the images downloaded by the download unit 44, and sends the extracted image groups to the car display 12 of the car 1 via the elevator control device 2. (See below for further details.) Figure 13 Here is an example of the detailed drawing process of the drawing section 47.

[0067] The camera image output unit 48 acquires the images captured by the building camera 5 or the maintenance camera 6, and sends the captured images to the car 1 via the elevator control device 2, so that the images are displayed on the display 12 inside the car or on the wall of the car 1.

[0068] <Example of computer hardware architecture>

[0069] Next, refer to Figure 2 To explain the composition Figure 1 The structure (hardware structure) of the control system of each device in the elevator system 100 shown.

[0070] Figure 2 This is a block diagram illustrating an example of the hardware structure of the various devices constituting the elevator system 100. Figure 2 The computer 200 shown is hardware used as a so-called computer.

[0071] 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 memory 204, and a communication I / F (Interface) 205, all connected to the bus B.

[0072] CPU 201 reads the program code of the software that implements the functions involved in this embodiment from ROM 202, expands it in RAM 203, and executes it. Alternatively, CPU 201 directly reads the program code from ROM 202 and executes it unchanged. Furthermore, computer 200 may replace CPU 201 with a processing device such as MPU (Micro-Processing Unit). Variables, parameters, etc., generated during the CPU 201's computational processing are temporarily written into RAM 203.

[0073] The functions of each part constituting the drawing device 4 are implemented by the CPU 201 reading the program used to implement these functions from the ROM 202 and executing it.

[0074] As a non-volatile storage device 204, it can be, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a floppy disk, an optical disk, an optical disc, a CD-ROM, a CD-R, or a non-volatile memory card. In addition to the OS (Operating System) and various parameters, this non-volatile storage device 204 also records programs used to enable the computer 200 to function. The functions of the archive unit 3 are implemented through the non-volatile storage device 204.

[0075] Alternatively, the program can also be stored in ROM 202. The program is stored in the form of computer-readable program code, and CPU 201 executes the actions that follow the program code sequentially. That is, ROM 202 or non-volatile memory 204 is used as an example of a computer-readable, non-transitory recording medium for storing a program executed by a computer.

[0076] The Communication I / F205 consists of communication devices that control communication with other devices. The networks used for communication control by the Communication I / F205 include, for example, serial communication in the form of multidrop connections like RS-485, and communication lines providing multiple topologies like Ethernet (registered trademark). Among the communication lines providing multiple topologies, there are LAN (Local Area Network) and WAN (Wide Area Network) as wired communication lines, and RAN (Radio Area Network) as wireless communication lines.

[0077] Furthermore, for example, in the network where communication control is performed by the communication I / F205, there are wireless networks such as Wi-Fi (registered trademark) and wireless communication infrastructures. The functions of the input / output information receiving unit 21 and the data output unit 22 of the elevator control device 2 are realized through the communication I / F205.

[0078] <Methods for photographing landscapes outside buildings and examples of image groups obtained through this method>

[0079] Next, refer to Figure 3 This illustrates a method for photographing scenery outside buildings and provides examples of the resulting image sets. Figure 3 This is an example diagram illustrating a method of photographing scenery outside buildings and a group of images obtained through that photograph.

[0080] exist Figure 3 The image shows the scenery outside a building captured by drone 7. Drone 7 is positioned outside the building, for example, along... Figure 3 The drone moves upwards in the direction indicated by the upward arrow while capturing images. The three vertical rectangles, indicated by dashed lines, surrounding the drone 7 represent image groups 101 to 103 generated based on the images captured by the drone 7.

[0081] Image groups 101 to 103 are longitudinal image groups that correspond to the three sides of the building and include the entire landscape from the vicinity of the ground on each side to the top of the building. Figure 3Regions 104 to 106, highlighted in color, represent the areas being photographed by the drone 7. The altitude position information of the drone 7 is linked to the images captured in these regions and stored accordingly. That is, image groups 101 to 103 are image groups each containing altitude position information. When the drone 7 photographs a range from the ground floor to the top floor of a building while changing its shooting altitude, image groups 101 to 103 each contain altitude position information (distance from the ground in the vertical direction) corresponding to the height from the ground floor to the top floor of the building.

[0082] In addition, Figure 3 The example given is an image group with a longitudinal shape having a long side corresponding to the height of the building, but the present invention is not limited to this. Regarding the image group, it can also be constructed using multiple captured images corresponding to the capturing areas 104 to 106, etc. In this case, different height position information is established and stored in correspondence with each of the multiple captured images. Furthermore, if the car 1 moves in a direction other than vertical, an image group corresponding to the direction of movement of the object can be provided. In this case, the image group is not a longitudinal shape, but rather an image that is long in the direction of movement. That is, in the image group according to the present invention, the image constructed by a structure that can display external images within the range that the car 1 can move is the object.

[0083] In addition, Figure 3 The example shown illustrates the generation of three image groups 101 to 103 corresponding to the three sides of the car 1, but the present invention is not limited thereto. The image groups can be provided corresponding to the sides of the in-car display 12 on which the images are displayed, and the number of them can be one, two, or four.

[0084] <Resolution setting process in the resolution setting section>

[0085] Next, refer to Figure 4 as well as Figure 5 To explain the resolution setting section 43 (reference) Figure 1 A summary of the resolution setting process.

[0086] Figure 4 This is a diagram showing information about the dimensions of the in-car display 12 (labeled "object device" in the figure) that displays images based on image groups. Figure 4 In the diagram, the horizontal (X) dimension of the in-car display 12 is shown as "X0", and the vertical (Y) dimension is shown as "Y0". The resolution setting unit 43 sets (defines) the resolution of the extraction range when extracting an image from an image group that corresponds to the size of the in-car display 12. The resolution setting unit 43 sets the width and coordinate axes in the X and Y directions as the resolution.

[0087] If Figure 3 If the entire area of ​​image group 102 is scaled down to the size of the in-car display 12 and displayed, the aspect ratio of the image displayed on the in-car display 12 will change, and the image will be distorted. In order to prevent such distortion, the resolution setting unit 43 sets the resolution to reproduce as faithfully as possible the aspect ratio and scale of the scenery outside the building that can be seen from the in-car display 12 when it is used as a window.

[0088] Figure 5 This is a diagram showing the dimensions of the two walls inside car 1 when the object displaying the image is the wall inside car 1. Figure 5 The wall 16a (labeled "object device (1)" in the figure) where the image is projected by projector 15a is shown to have a horizontal (X) dimension of "X1" and a vertical (Y) dimension of "Y1". In addition, the wall 16b (labeled "object device (2)" in the figure) where the image is projected by projector 15b is shown to have a horizontal (X) dimension of "X2" and a vertical (Y) dimension of "Y2".

[0089] When the object of the image display is the wall inside the car 1, the resolution setting unit 43 also sets the resolution of the extraction (description) range as a parameter when the image is extracted from the image group and displayed (depicted) on the object device based on the size of the image display area.

[0090] <Description Scope Determination Processing in the Description Scope Determination Department>

[0091] Next, refer to Figure 6 as well as Figure 7 To explain the scope determination section 46 (see reference) Figure 1 The scope of the description determines the outline of the process.

[0092] Figure 6 This diagram shows the outline of the processing where the object of the image display is the in-car display 12. Figure 7 This is a diagram showing the outline of the processing where the object of the image display is the wall of car 1.

[0093] exist Figure 6 The left side shows a longitudinal image group 101 to image group 103. Figure 6The right side shows the car 1 at a certain height. The drawing range determination unit 46 determines the height position H1 within the image group of the image group to be extracted (drawn) from the image group (drawn on the object device) 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 drawing range determination unit 46 determines the height position H1 of the drawing range in the image group based on the height position obtained by compensating (correcting) the height position of the building for the height position of the car 1 shown in the absolute position detection information. The height position H1 is the height from the bottom edge to the center of the drawing range 110, as described later. (Refer to the following description.) Figure 8 Let's take a detailed look at an example of adjusting the height position based on the building's height location.

[0094] The drawing range determination unit 46 determines the drawing range 110 of the image on the car display 12 based on the height position and the resolution set by the resolution setting unit 43. Then, the drawing unit 47 extracts the image within the drawing range 110 determined by the drawing range determination unit 46 from the image group downloaded by the download unit 44. Afterward, the drawing unit 47 sends the extracted image to the car display 12 of the car 1 via the elevator control device 2 and displays it. By performing this processing by the drawing range determination unit 46 and the download unit 44, the amount of data in the image group downloaded from the archive unit 3 can be reduced.

[0095] exist Figure 7 The diagram shows an example of the depiction range when the display object of the image is the wall of the car 1 and the number of display surfaces is two. In this case, the depiction range determination unit 46 determines the depiction range 111 to depiction range 112 of the image in each of the image group 101 corresponding to the first surface of the 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 the car 1.

[0096] Next, refer to Figure 8 To illustrate a modified example of the absolute position of the car 1 based on the height position detection unit 45. Figure 8 It is a diagram showing the absolute position of car 1, the height position of the building, and the height position of the image group.

[0097] exist Figure 8The diagram illustrates an example of a building B equipped with an elevator 10a for upper floors and a shuttle elevator 10b that transports passengers to the departure floor of elevator 10a. The shuttle elevator 10b has a vertical range from the basement level to the departure floor of elevator 10a, with a height of "210 (m)". In this case, the lower limit of the absolute position of the shuttle elevator 10b, i.e., "0", corresponds to the height of the floor of the basement level, and the upper limit of the absolute position, i.e., "210", corresponds to the height of the departure floor (ceiling position) of elevator 10a.

[0098] 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 set to "100 (m)". In this case, the lower limit of the absolute position of elevator 10a, i.e., "0", corresponds to the height position of the floor of the departure floor of elevator 10a, and the upper limit of the absolute position, i.e., "100", corresponds to the height position of the top floor (ceiling position) of elevator 10a.

[0099] On the other hand, the height position "0" of building B corresponds to the height position of the bottom of building B located in the basement, and the height position "300" corresponds to the height position of the top floor (ceiling position). Since image group 101 captures the scenery from the ground to the top floor of building B, its lower limit value of height position, "0", corresponds to the height position of the ground floor, and its upper limit value of "280" corresponds to the height position of the top floor (ceiling position) of building B. The actual height position of the top floor of building B is "300", but since this value is based on the case where the bottom of building B is taken as the starting point, "280" based on the case where the ground floor is taken as the starting point becomes the upper limit value of the height position of image group 101.

[0100] For example, the image display object is envisioned to be the upper-level group using elevator 10a. In this case, the height position detection unit 45 compensates for the absolute position "0" detected in elevator 10a with the height position of building B, i.e., "200". Then, the drawing range determination unit 46 sets the height position "180" in the image group 101 associated with the compensated "200" as the height position of the image's drawing range.

[0101] By performing this processing through the height position detection unit 45 and the depiction range determination unit 46, it is possible to display a view of the outside of the building corresponding to the height position of the elevator car 1 within the building B without having to prepare multiple images corresponding to the travel mode in advance. Furthermore, regardless of the elevator's height position, it is possible to display a view of the outside of the building corresponding to the height position of the elevator car 1.

[0102] Furthermore, in elevators where the height position information of the car 1's lifting range corresponds to the height position information of the building B, the depiction range determination unit 46 may not perform correction based on the height position of the building B, but instead determine the height position of the image depiction range within the image group based on the absolute position detection information. Alternatively, the user may set any correction position, setting their preferred position as the ground floor.

[0103] <Drawing Mode Setting Processing in the Drawing Mode Setting Department>

[0104] Next, refer to Figure 9 Let me explain the drawing mode setting process of the drawing mode setting unit 41. Figure 9 This is a flowchart illustrating an example of the process of setting the drawing mode in the drawing mode setting unit 41.

[0105] First, the mode setting unit 41 determines whether the settings of the device used for setting the maintenance mode are enabled (step S1). The device used for setting the maintenance mode may include, for example, buttons or switches. Alternatively, instead of switching between ON and OFF on such a device, the activation of the maintenance mode may be indicated by commands from an external device (not shown) or by triggers input based on a schedule table.

[0106] If, in step S1, it is determined that the setting of the device used for setting the maintenance mode is valid (if step S1 is "yes"), the drawing mode setting unit 41 enables the setting of the maintenance mode (step S2). On the other hand, if, in step S1, it is determined that the setting of the device used for setting the maintenance mode is invalid (if step S1 is "no"), the drawing mode setting unit 41 determines whether the setting of the device used for setting the real-time shooting mode is enabled (step S3).

[0107] The device used for setting the real-time shooting mode is similar to that used for setting the maintenance mode, consisting of, for example, buttons and switches. Alternatively, the activation of the real-time shooting mode can be indicated by commands from external devices, triggers based on schedule inputs, etc.

[0108] In step S3, if the device setting for the real-time shooting mode is determined to be valid (if step S3 is "yes"), the drawing mode setting unit 41 enables the real-time shooting mode setting (step S4). On the other hand, if the device setting for the real-time shooting mode is determined to be invalid (if step S3 is "no"), the drawing mode setting unit 41 determines whether other location display services can be used (step S5).

[0109] The ability to use other location display services can be switched based on operations such as buttons and switches, or based on commands and triggers. In step S5, if it is determined that other location display services can be used (if step S5 is a "yes" determination), the drawing mode setting unit 41 activates the setting of other location display mode (step S6).

[0110] On the other hand, in step S5, if it is determined that the service cannot be displayed using other locations (if step S5 is determined as "No"), the drawing mode setting unit 41 determines whether a connection to the archive unit 3 can be established (step S7). Step S7 is determined as "Yes" if the service to the archive unit 3 is being provided and communication with the archive unit 3 is possible. On the other hand, if the service to the archive unit 3 is not provided, or if communication with the archive unit 3 is not possible due to communication obstacles, step S7 is determined as "No".

[0111] If the determination in step S7 is "yes", the drawing mode setting unit 41 enables the setting of the archive display mode (step S8). After the processing in step S8, or if the determination in step S7 is "no", the drawing mode setting process of the drawing mode setting unit 41 ends.

[0112] <Drawing Mode Determination Processing in the Drawing Mode Determination Unit>

[0113] Next, refer to Figure 10 The drawing mode determination process of the drawing mode determination unit 42 will be explained. Figure 10 This is a flowchart illustrating an example of the process of determining the depiction mode by the depiction mode determination unit 42.

[0114] First, the drawing mode determination unit 42 determines whether the maintenance mode setting is valid (step S11). In step S11, if the maintenance mode setting is valid (if step S11 is "yes"), the drawing mode determination unit 42 determines whether a transition to maintenance mode has occurred (step S12). In step S12, if the transition to maintenance mode is determined (if step S12 is "yes"), the drawing mode determination unit 42 determines that the drawing mode is maintenance mode (step S13). If maintenance mode is determined, the image captured by the maintenance camera 6 obtained by the camera image output unit 48 is displayed on the car interior display 12 or the wall of the car 1.

[0115] If the determination in step S11 is "No", or if the determination in step S12 is "No", the drawing mode determination unit 42 determines whether the setting of the real-time shooting mode is valid (step S14). In step S14, if the setting of the real-time shooting mode is determined to be valid (if the determination in step S14 is "Yes"), the drawing mode determination unit 42 determines whether a transition to the real-time shooting mode has been performed (step S15).

[0116] In step S15, if it is determined that the mode will switch to real-time shooting mode (if step S15 is "yes"), the drawing mode determination unit 42 determines that the drawing mode is real-time shooting mode (step S16). If it is determined to be real-time shooting, the image captured by the building camera 5 obtained by the camera image output unit 48 is displayed on the car display 12 or the wall of the car 1.

[0117] If the determination in step S14 is "No", or if the determination in step S15 is "No", the drawing mode determination unit 42 determines whether the setting of the display mode in another position is valid (step S17). In step S17, if the setting of the display mode in another position is determined to be valid (if the determination in step S17 is "Yes"), the drawing mode determination unit 42 determines whether a transfer to the display mode in another position has been performed (step S18).

[0118] In step S18, if it is determined that the display mode has been switched to another location (if step S18 is "yes"), the drawing mode determination unit 42 determines that the drawing mode is the other location display mode (step S19). If it is determined to be the other location display mode, the in-car display 12 or the wall of the car 1 displays the captured images from other locations obtained by the server or the archive unit 3 (not shown).

[0119] If step S17 is determined to be "No", or if step S18 is determined to be "No", the drawing mode determination unit 42 determines whether the setting of the archive display mode is valid (step S20). In step S20, if the setting of the archive display mode is valid (if step S20 is determined to be "Yes"), the drawing mode determination unit 42 determines whether a transfer to the archive display mode has been performed (step S21).

[0120] In step S21, if it is determined that the mode should be switched to the archive display mode (if step S21 is "yes"), the drawing mode determination unit 42 determines that the drawing mode is the archive display mode (step S22). If the mode is determined to be the archive display mode, the image of the image group 33 obtained from the archive unit 3, etc., is displayed on the car display 12 or the wall of the car 1.

[0121] If the determination is "No" in step S20, or "No" in step S21, the drawing mode determination unit 42 determines whether there is no mode setting and the archive unit 3 cannot be used (step S23). After the processing of steps S13, S16, S19, S22 or S23, the drawing mode setting process of the drawing mode determination unit 42 ends.

[0122] <Resolution setting process in the resolution setting section>

[0123] Next, refer to Figure 11 Let me explain the resolution setting process of the resolution setting unit 43. Figure 11 This is a flowchart illustrating an example of the resolution setting process of the resolution setting unit 43.

[0124] First, the resolution setting unit 43 determines whether the number of display surfaces of the image inside the car 1 is more than one (step S31). In step S31, if it is determined that the number of display surfaces is more than one, that is, two or more (if step S31 is "yes"), the resolution setting unit 43 sets the information of the number of display surfaces as a parameter (step S32).

[0125] Next, the resolution setting unit 43 sets the size of each object device corresponding to each number of faces (step S33). Object devices include, for example, the in-car display 12 and the display area on the wall inside the car 1. Next, the resolution setting unit 43 sets the resolution of each depicted area of ​​the image when the image is extracted from the image group and displayed on the object device (step S34).

[0126] On the other hand, in step S31, if it is determined that the number of display surfaces of the image inside the car 1 is 1 (if step S31 is determined to be "No"), the resolution setting unit 43 sets the size of the object device present on that surface (step S35). Next, the resolution setting unit 43 sets the resolution of the image's depiction area (step S36). After the processing in step S34 or step S36, the resolution setting process of the resolution setting unit 43 ends.

[0127] Download Processing in the Download Department

[0128] Next, refer to Figure 12 This explains the download processing of download section 44. Figure 12 This is a flowchart illustrating an example of the download processing procedure of the download unit 44.

[0129] First, the download unit 44 determines whether the set mode is a display mode for another location (step S41). In step S41, if it is determined that the mode is set to another location (if step S41 is "yes"), the download unit 44 extracts the image of the other location corresponding to the current display time from the archive unit 3 (step S42). Furthermore, the current time and the display time do not need to strictly correspond; if the current time is early morning, the download unit 44 can extract the morning image, and if it is midday, the download unit 44 can extract the daytime image, and so on.

[0130] Next, the download unit 44 determines the location (region, orientation, etc.) to be displayed on the target device from images captured at other locations (step S43). The location can be determined based on predetermined settings or based on input from users of elevators, etc. Next, the download unit 44 downloads the image group (data) corresponding to the display location from the archive unit 3 at the resolution set by the resolution setting unit 43 (step S44).

[0131] On the other hand, in step S41, if it is determined that it is not a display mode for other positions (if step S41 is determined to be "No"), the download unit 44 determines whether the mode is the archive display mode (step S45). In step S45, if it is determined that it is the archive display mode (if step S45 is determined to be "Yes"), the download unit 44 extracts the captured images from other positions corresponding to the current display time (step S46).

[0132] Next, the download unit 44 extracts the image group (data) of the time period (period, era, etc.) to be downloaded (step S47). Next, the download unit 44 downloads the image group (data) to be downloaded from the archive unit 3 at the resolution set by the resolution setting unit 43 (step S48).

[0133] On the other hand, in step S45, if it is determined that the file display mode is not being used (if step S45 is a "no" determination), and if there is downloaded data, the download unit 44 clears it (step S49). Afterwards, the drawing unit 47 performs a process to clear the ROM 202 (see reference 4) stored in the drawing device 4. Figure 2 The image display (description) of the target device is controlled. After the processing of step S44, step S48 or step S49, the download process of the download unit 44 ends.

[0134] <Height position detection unit, drawing range determination unit, and processing of the drawing unit>

[0135] Next, refer to Figure 13 The processing of the height position detection unit 45, the drawing range determination unit 46, and the drawing unit 47 will be explained. Figure 13 This is a flowchart illustrating an example of the processes of height position detection processing of height position detection unit 45, drawing range determination processing of drawing range determination unit 46, and drawing processing of drawing unit 47.

[0136] First, the height position detection unit 45 receives the absolute position detection information of the car 1 sent from the elevator control device 2 (step S51). Next, the height position detection unit 45 corrects the height position information of the car 1 based on the height of the building B (step S52). That is, the height position detection unit 45 sets the height position of the car 1 obtained by compensating the height position of the car 1 shown in the absolute position detection information of the car 1 with the height position of the building B as the height position of the car 1.

[0137] Next, the drawing range determination unit 46 determines the drawing range based on the information of the height position of the car 1 corrected in step S52 (step S53).

[0138] Next, the drawing unit 47 determines whether there is downloaded data that has been downloaded by the download unit 44 (step S54). In step S54, if it is determined that there is downloaded data (step S54 is a "yes" determination), the drawing unit 47 extracts the image (data) corresponding to the drawing area based on the downloaded data (step S55). Then, the drawing unit 47 sends the extracted data to the in-car display 12 (or projector, etc.) via the elevator control device 2 (step S56).

[0139] On the other hand, in step S54, if it is determined that no data has been downloaded (if step S54 is a "no" determination), the data stored in ROM 202 (see reference) is processed. Figure 2 The drawing unit 47 extracts an image corresponding to the drawing area from data such as elevator control device 2 (step S57). Next, the drawing unit 47 performs the processing in step S56. That is, the extracted image (data) is sent to the in-car display 12 (or projector, etc.) via the elevator control device 2. After the processing in step S56, the drawing process of the drawing unit 47 ends.

[0140] In addition, based on Figure 13 In the case of processing a group of readout images, the frame rate for readout (description) is preferably set to a rate corresponding to the elevator's rated speed. When the elevator's rated speed is relatively high, even if the frame rate is low, it is difficult for frame drops to occur in the displayed image. On the other hand, when the rated speed is constant, if the frame rate is low, there is a possibility that the target device will display an image frame by frame.

[0141] For example in Figure 3When the elongated image groups 101 to 103 shown are depicting objects, the frame rate can be adjusted by changing the interval (distance interval in the height direction) at which the height position information corresponding to the image group is established. Furthermore, when the image group consists of... Figure 3 When the image collection corresponding to the shooting area 104 shown is constituted, the frame rate can be adjusted by changing the number of images corresponding to the height position (the distance interval between the images corresponding to the height positions). Then, by setting the frame rate of the image depiction to the optimal rate corresponding to the rated speed of the elevator, frame drops and other issues can be prevented in the image depicting the object equipment inside the car 1.

[0142] The elevator system 100 described in the above embodiment displays an image of the exterior of the elevator car 1 or the exterior of the building B where the elevator is located in a display area (object device) within the elevator car 1. Furthermore, the elevator system 100 includes: a height position detection unit 45 that acquires absolute position detection information representing the absolute position of the car 1 in the vertical direction within the elevator shaft; and a drawing unit 47 that extracts an image group from the storage unit 3 containing height position information corresponding to the absolute position detection information of the car acquired by the height position detection unit 45, and displays it in the display area within the car car 1.

[0143] Therefore, according to the above-described embodiment, without pre-preparing images for each travel mode, images of the exterior of the building B equipped with the elevator can be displayed in the display area inside the car 1 in conjunction with the lifting and lowering movements of the car 1. As a result, elevator users can enjoy views of the scenery outside the building B while riding in the car 1, thus enabling them to recover their spirits even in confined situations such as when measures against infectious diseases are needed.

[0144] <Variation Example 1>

[0145] Furthermore, in the above-described embodiments, the position detector 14 (see reference) is an example. Figure 1 This invention provides an example of detecting the absolute position of car 1, but it is not limited to this. The absolute position (height position) of car 1 can also be calculated based on position information estimated based on position correction information, time elapsed information, etc.

[0146] Figure 14 This is a diagram showing a schematic structural example of the elevator system 100A involved in Modification Example 1. Figure 14 The elevator system 100A shown is Figure 1 The elevator system 100 shown differs in that the elevator control device 2A includes an absolute position calculation unit 23. Other structural details are identical to those of the elevator system 100 and will not be repeated here.

[0147] Figure 15 This is a flowchart illustrating an example of the absolute position calculation process of the absolute position calculation unit 23 of the elevator system 100A involved in Modification Example 1.

[0148] First, the absolute position calculation unit 23 determines whether there is position correction information (step S61). The position correction information consists of a correction value calculated based on the difference between the position of the car 1 detected by the position detector 14A and the actual position of the car 1.

[0149] In Modification 1, the position detector 14A detects the position of the car 1 in the lifting channel based on, for example, the number of rotations of the traction machine motor (not shown) since departure from the ground floor. The actual height position of the car 1 is obtained based on the detection results of the position of the hole in the shielding plate (not shown) in the lifting channel of the optical sensor (not shown) located on the outside of the car 1.

[0150] In step S61, if it is determined that there is position correction information (if step S61 is "yes"), the absolute position calculation unit 23 performs position correction (correction of the height position of the car 1) using the position correction information (step S62). Then, the absolute position calculation unit 23 outputs the position information corrected in step S62 as the absolute position information of the car (step S63).

[0151] On the other hand, in step S61, if it is determined that there is no position correction information (if step S61 is determined to be "no"), the absolute position calculation unit 23 extracts the time of the previous stopping position of the car 1 or the clock count of the travel pulse of the car 1 (step S64).

[0152] Next, the absolute position calculation unit 23 calculates the travel distance of the car 1 based on the time of the previous stopping position extracted in step S64 or the clock count of the travel pulse, and estimates the current position of the car 1 based on this travel distance (step S65). Then, the absolute position calculation unit 23 performs the processing of step S63. That is, the absolute position calculation unit 23 outputs the information of the current position of the car 1 estimated in step S65 as the absolute position information of the car 1. After the processing of step S63, the absolute value calculation processing of the absolute position calculation unit 23 ends.

[0153] According to Modification 1, the same effect as that obtained by the above-described embodiment can be obtained in an elevator system without a device for detecting the absolute position of the car 1.

[0154] <Variation Example 2>

[0155] Next, refer to Figures 16-18The elevator system 100B and its display control method according to Modification 2 of the present invention will be described below. The elevator system 100B according to Modification 2 displays images (image group) read from the archive unit 3 corresponding to the height position of the car 1, and also displays information about the surroundings of the pre-prepared building B.

[0156] Figure 16 This is a diagram showing a schematic structural example of the elevator system 100B involved in Modification Example 2. Figure 16 The elevator system 100B shown is Figure 1 The elevator system 100 shown differs in that it stores peripheral information 35 in the storage unit 3A and the drawing device 4A has a peripheral information output unit 49. Other structures are identical to those in the elevator system 100, therefore, repeated descriptions are omitted.

[0157] Surrounding Information 35 stores the coordinates, names, and shapes (frames) of various facilities surrounding Building B, such as tourist attractions, restaurants, and shops. Additionally, Surrounding Information 35 may also include other information.

[0158] The peripheral information output unit 49 reads the corresponding peripheral information 35 from the archive unit 3A based on the information of the image depiction range determined according to the height position of the car 1, and outputs it to the depiction unit 47. Then, the depiction unit 47 overlays the peripheral information input from the peripheral information output unit 49 onto the image read from the archive unit 3A, so that it is displayed inside the car 1.

[0159] Figure 17 This is a flowchart illustrating an example of the peripheral information output process of the peripheral information output unit 49. First, the peripheral information output unit 49 determines whether peripheral information 35 is registered in the archive unit 3A (step S71). In step S71, if it is determined that peripheral information 35 is registered (step S71 is a "yes" determination), the peripheral information output unit 49 obtains information about the image's depicted position (range) and the peripheral information 35 that can be displayed (step S72). The peripheral information 35 that can be displayed includes peripheral information located within a predetermined distance range from building B, peripheral information located within a range that can be visually recognized as an image, etc.

[0160] Next, the peripheral information output unit 49 determines the position (coordinates) in the peripheral information 35 of the image corresponding to the drawing area (step S73). Then, based on the position information determined in step S73, the peripheral information output unit 49 outputs the normal image (the image read from the archive unit 3A) and the image of the peripheral information (peripheral image) to the drawing unit 47 in a corresponding manner (step S74).

[0161] On the other hand, in step S71, if it is determined that no surrounding information has been registered (if step S71 is determined to be "no"), the surrounding information output unit 49 reads the normal image from the archive unit 3A and outputs it to the drawing unit 47 (step S75). After the processing in step S74 or step S75, the surrounding information output processing of the surrounding information output unit 49 ends.

[0162] Figure 18 This is an example diagram showing an image displayed with surrounding information superimposed. In Figure 18 The image shown illustrates a layout where surrounding information is overlaid on an image of the view visible from building B. Figure 18 In the example shown, the text within the speech bubble clearly indicates that "Sightseeing Area A", "Tenants B and C", "Restaurants B and C", etc. are located around Building B.

[0163] According to variation example 2, elevator users can confirm the names, locations, and other information of facilities surrounding building B while riding in car 1.

[0164] <Variation Example 3>

[0165] Next, refer to Figure 19 as well as Figure 20 The present invention will be described in detail in Modification 3 of the present invention, which relates to an elevator system 100C and a display control method for the elevator system 100C. The elevator system 100C in Modification 3 displays information (surrounding information 35) around the building B by superimposing an image actually captured by the building camera 5.

[0166] Figure 19 This is a diagram showing a schematic structural example of the elevator system 100C involved in Modification Example 3. Figure 19 The elevator system 100C shown is Figure 16 The elevator system 100B shown differs in that: the archive unit 3B only has ID 31 and peripheral information 35; and the drawing device 4B only has a drawing range determination unit 46, a peripheral information output unit 49A, and a drawing unit 47. Other structures are the same as those in the elevator system 100B, therefore, repeated descriptions are omitted.

[0167] Figure 20 This is a flowchart illustrating an example of the peripheral information output processing procedure of the peripheral information output unit 49A. Because... Figure 20 Steps S81 and S82 are respectively with Figure 17 Steps S71 and S72 are the same, therefore, their descriptions are omitted.

[0168] In step S83, the peripheral information output unit 49A determines the position of the peripheral information of the depicted area. In variation 3, the depicting device 4B overlays the peripheral information 35 onto the image read from the archive unit 3B, but onto the image captured in real time by the building camera 5. Therefore, the peripheral information output unit 49A establishes the correspondence between the captured image and the peripheral information by matching the captured image of the building camera 5 and the peripheral information using pattern matching.

[0169] After step S83, the peripheral information output unit 49A outputs an image with corresponding peripheral information to the drawing unit 47 (step S84). After step S84, the peripheral information output processing of the peripheral information output unit 49A ends.

[0170] According to variation 3, elevator users can obtain more accurate information about the surroundings because they can confirm the surrounding information displayed overlaid with the actual scenery seen from building B.

[0171] <Other variations>

[0172] Furthermore, in the above-described embodiments and various modifications, examples are given of displaying images with height position information corresponding to the height position of the car 1 in a display area inside the car 1, but the present invention is not limited to this. For example, in Figure 8 The shuttle elevator 10b shown can also display a group of images showing the height position information of the upper-floor elevator 10a. Such control can be achieved, for example, by receiving height position information (or information about buildings, scenery, etc., corresponding to the height position information) of the desired image (to be displayed in the car 1) input by the elevator user via the in-car display 12, a portable terminal (not shown), or similar means. By performing such control, elevator users can see images from their preferred height position within the car 1. For example, while riding a lower-floor elevator, users can virtually enjoy the scenery seen from a higher-floor elevator, resulting in a high level of mental relaxation.

[0173] Furthermore, for example, it is easy to conceive of a structure where the car 1 can display an image corresponding to the direction of movement of the object. In this case, it is necessary to prepare a group of images corresponding to the distance for the direction of movement. Furthermore, while the above-described embodiments and variations describe the correction of the height position, by setting an arbitrary position as the starting position of the car's movement, the present invention can also be applied to cars moving in directions other than the horizontal direction.

[0174] Furthermore, the above-described embodiments and variations have been provided to illustrate the structure of the apparatus and system in detail for ease of understanding of the present invention, but are not limited to having all the structures described.

[0175] In addition, Figure 1 , Figure 14 , Figure 16 , Figure 19 Control lines or information lines, indicated by solid lines or single arrows, are lines deemed necessary for illustration, but it is not necessary to show all control lines or information lines on the product. In practice, almost all structures can be considered interconnected.

[0176] Furthermore, the processing steps described in this specification for processing time series certainly include processing performed on the time series in the order described, but are not necessarily performed on the time series. They also include parallel or separate processing (e.g., parallel processing or object-based processing).

[0177] Furthermore, each component of the elevator system described in the above-described embodiment or variations of the present invention can be installed on any hardware, provided that its respective hardware can send and receive information with each other via a network. In addition, the processing performed by a certain processing unit can be implemented by a single hardware unit or by distributed processing by multiple hardware units.
