Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments will be described with reference to the drawings. In each figure, elements that are common are denoted by the same reference numerals, and redundant explanations are omitted.

[0014] 1. Embodiment 1. 1-1. Overview of the Elevator Display System in Embodiment 1 FIG. 1 is a diagram showing a configuration example of the elevator display system according to Embodiment 1. The display system 100 is a system that generates an illustrative image overlooking the usage status of the elevator and displays the generated illustrative image in the air. The illustrative image here includes figures, or combinations of figures and colors or characters, etc. The illustrative image may be a still image, or may include video material or a video with an animation effect in a part or all of it.

[0015] The elevator to which the display system 100 is applied is installed in a facility consisting of a building with multiple floors. In the facility, an elevator shaft is provided. The shaft is a long vertical space that spans multiple floors. On each floor of the facility, an elevator landing 4 is provided. The landing 4 is located adjacent to the shaft. A landing door 6 is provided at the entrance to the landing 4 on each floor. The landing door 6 is a door that separates the landing 4 from the shaft. The landing door 6 is, for example, a center-opening type in which two panels open and close horizontally with the center of the landing entrance as the door closing position. The landing door 6 may also be a single-opening type in which two panels open and close horizontally starting from the door closing position at the right or left end of the landing entrance.

[0016] The elevator comprises a car 2 and a door opening / closing control device 22. The car 2 is a device that transports passengers and others inside between multiple floors by traveling vertically in the hoistway. The car 2 is equipped with a pair of car doors 3 at the car entrance that can be opened and closed horizontally. Of the two types of car doors 3, the same type as the landing doors 6 is adopted.

[0017] The car door 3 is opened and closed by the door opening / closing control device 22 in conjunction with the landing door 6 of the landing 4 on any floor, so that when the car 2 stops on any floor, users can board and alight at the landing 4 and car 2 on that floor. In other words, the door opening / closing control device 22 functions as a device that controls the opening and closing of the elevator doors, including the car door 3 and the landing door 6. There are no limitations on the configuration of the door opening / closing control device 22. The door opening / closing control device 22 may be configured to mechanically engage and interlock the landing door 6 with the car door 3, or it may be configured to electrically interlock and open and close each door. In the following description, the time from when the door opening / closing control device 22 opens the elevator doors until they close will be referred to as the "door opening time".

[0018] The display system 100 comprises an aerial display device 10, an imaging device 20, a management server 30, and the aforementioned door opening / closing control device 22. The management server 30 is connected to the aerial display device 10, the imaging device 20, and the door opening / closing control device 22, respectively, via a communication network 8 such as the Internet.

[0019] The aerial display device 10 has the function of displaying illustration images output from the management server 30, which will be described later, in the air. The aerial display device 10 is installed, for example, on the wall of the boarding area 4 and displays the illustration images in the air facing the boarding area 4.

[0020] Figure 2 shows an example of an aerial display device. In the example shown in Figure 2, the aerial display device 10 comprises a display unit 12, a beam splitter 14, and a retroreflective material 16. The display unit 12 displays an image. Light emitted from the display unit 12 is incident on the beam splitter 14. The beam splitter 14 reflects the light from the display unit 12. The light from the display unit 12 reflected by the beam splitter 14 is incident on the retroreflective material 16. The retroreflective material 16 has the function of reflecting light incident from a light source back towards that light source. Therefore, the light from the display unit 12 reflected by the beam splitter 14 is reflected back to the beam splitter 14 by the retroreflective material 16. The light from the display unit 12 reflected by the retroreflective material 16 is transmitted through the beam splitter 14. Light from the retroreflective material 16 that has passed through the beam splitter 14 forms an image at the relative position between the beam splitter 14 and the display unit 12. In this way, the generated image is displayed on the display unit 12, and the illustration image is displayed in the air at a position away from the wall surface of the landing 4 where the aerial display device 10 is installed. In the following explanation, the illustration image displayed in the air by the aerial display device 10 will also be referred to as the "aerial image".

[0021] Furthermore, there are no limitations on the imaging method of the aerial display device 10. In other words, the aerial display device 10 may be configured to display an aerial image by employing an imaging method using an orthogonal mirror array or a hexahedral prism element.

[0022] The imaging device 20 is a camera installed to capture images inside the elevator car 2. The imaging device 20 periodically captures and outputs images of passengers riding inside the elevator car 2. There are no limitations on the type, number, or installation location of the imaging device 20 within the elevator car 2. The image data captured by the imaging device 20 is hereinafter referred to as "image data." The image data is not limited to still images; it may also be video data. The image data is transmitted to the management server 30 via a communication network 8 such as the Internet.

[0023] The management server 30 functions as an information processing device that processes information. Typically, the management server 30 receives imaging data periodically captured by the imaging device 20. This process is hereinafter referred to as the "acquisition process". Based on the acquired imaging data, the management server 30 analyzes the attributes of users within the analysis range. This process is hereinafter referred to as the "analysis process". The information analyzed by the analysis process is hereinafter referred to as "user information". Here, user information includes information for distinguishing user attributes, such as attributes like adult, child, stroller, trolley, wheelchair, and robot, and the degree of congestion within the analysis range. The degree of congestion is expressed as a stepped index, such as "low," "medium," and "high." In the analysis process, the degree of congestion is analyzed based on the attributes of users within the analysis range, the number of users, and the size of the analysis range. The analysis range here is, for example, the area inside the basket 2. In the analysis process, for example, known image analysis processing techniques are used.

[0024] Furthermore, the management server 30 generates an illustration image to be displayed in the air by the aerial display device 10 based on the user information analyzed by the analysis process. This process is hereinafter referred to as the "image generation process". An example of the illustration image is an illustration that depicts the status of users in cart 2, including the attributes of the users in cart 2 and the level of congestion in cart 2, as an overview. The generated illustration image is displayed in the air by the aerial display device 10. This process is hereinafter referred to as the "display process".

[0025] Furthermore, the management server 30 determines whether or not a door opening extension operation is necessary to extend the door opening time. This process is hereinafter referred to as the "determination process". In the determination process, for example, if a user who requires time consideration for boarding and alighting, such as a stroller, trolley, or wheelchair, is riding in the car 2, it is determined that a door opening extension operation is necessary. If a door opening extension operation is necessary, the management server 30 controls the door opening / closing control device 22 to execute the door opening extension operation.

[0026] According to the display system 100 described above, an illustrated image showing an overview of the situation of users inside the elevator car 2 is generated and displayed in the air at the landing 4 prior to the arrival of the elevator car 2 at the landing 4. This makes it possible to inform users waiting to board at the landing 4 in advance of the situation inside the elevator car 2 through an easily recognizable overview.

[0027] 2. Display System Configuration Figure 3 is a block diagram showing an example of the configuration of the display system in Embodiment 1. The display system 100 comprises the aerial display device 10 described above, an imaging device 20, a door opening / closing control device 22, and a management server 30.

[0028] The management server 30 has the functionality of an information processing device as a computer. The management server 30 is located within the facility to be controlled. Alternatively, the management server 30 may be located in a remote location different from the facility to be controlled. As another example, the management server 30 may be implemented by a server on the cloud. If the management server 30 is located in a remote location, the management server 30 transmits or receives data to or from the aerial display device 10, the imaging device 20, and the door opening / closing control device 22 via a communication network 8 such as the Internet.

[0029] The management server 30 comprises at least one processor 40 and at least one memory 50. The memory 50, which serves as a storage device, stores at least one program 52 that can be executed by the processor 40, an illustration database 54, and various related data 56. The program 52 may be recorded on a computer-readable recording medium. The illustration database 54 stores data such as illustrations corresponding to user attributes and illustrations corresponding to congestion levels, which are used when generating illustration images.

[0030] The processor 40 executes program 52, thereby enabling various processes performed by the processor 40. Figure 4 is a block diagram showing the functions realized by the management server's processor executing the program. As shown in Figure 4, the processor 40 includes an acquisition unit 41, an analysis unit 42, an image generation unit 43, a display unit 44, a determination unit 45, and a command unit 46. The functions of the processor 40 will be described below with reference to Figure 1.

[0031] The acquisition unit 41 is a functional block for performing the acquisition process. In the acquisition process, the acquisition unit 41 acquires imaging data from the imaging device 20.

[0032] The analysis unit 42 is a functional block for performing analysis processing. In the analysis processing, the analysis unit 42 calculates the attributes of users in the elevator car 2 and the degree of congestion in the elevator car 2 by performing known image analysis processing on the acquired imaging data. For example, the degree of congestion is analyzed based on the attributes of users in the elevator car 2, the number of users, and the size of the elevator car 2. As an example, the degree of congestion is set in stages according to the ratio of the number of users to the capacity of the elevator car 2. In this case, the count of the number of users is changed according to the attributes of the users. For example, users with attributes such as wheelchairs, strollers, or trolleys, which require more occupied space than one adult, are counted as two users. The estimated user attributes and degree of congestion are temporarily stored as user information in the data 56 area of ​​memory 50.

[0033] The image generation unit 43 is a functional block for performing image generation processing to generate illustration images. In the image generation processing, the image generation unit 43 generates illustration images based on user information analyzed by the analysis processing. Specifically, the illustration DB 54 is used in the image generation processing.

[0034] Figure 5 is a functional block diagram showing the internal functions of the image generation unit 43. The image generation unit 43 includes a data acquisition unit 432 and an extraction unit 434. The data acquisition unit 432 is a functional block for acquiring user information necessary for generating illustration images. The extraction unit 434 is a functional block for extracting illustration images corresponding to the user information from the illustration DB 54 stored in the memory 50. The illustration DB 54 stores illustration images for each user attribute and each level of congestion, in which one or more user illustrations corresponding to the user's attributes are placed according to the level of congestion in an overhead view of the inside of the cart. The extraction unit 434 extracts illustration images corresponding to the user's attributes and level of congestion included in the user information.

[0035] Figure 6 illustrates illustrative images corresponding to user attributes. Figures (A) through (D) show illustrations of the user's situation inside the cart, categorized by user attribute. Figure (A) illustrates a case where the user is a person, illustrating an adult and a child riding together. Figure (B) illustrates a case where the user is using a wheelchair or stroller. Figure (C) illustrates a case where the user is using a trolley. And Figure (D) illustrates a case where the user is a self-propelled robot.

[0036] Figure 7 illustrates an illustration image that further reflects the degree of congestion in addition to the user attributes. The extraction unit 434 generates an illustration image by combining one or more illustrations extracted from the illustration DB 54 according to the degree of congestion. Figures 7(A) to (C) illustrate an overview of the state inside the elevator car when the user inside is a person and the congestion level is low, medium, and high. Figures 7(A) to (C) illustrate an illustration image in which the color corresponding to the congestion level is added to the inside of the elevator car.

[0037] The display unit 44 is a functional block for performing display processing. In the display processing, the display unit 44 displays the aerial image of the illustration generated by the image generation unit 43 on the aerial display device 10 prior to the arrival of the elevator car 2 at the landing 4.

[0038] The determination unit 45 is a functional block that performs a determination process to determine whether or not a door opening extension operation is necessary based on user information. The command unit 46 is a functional block that causes the door opening / closing control device 22 to execute the door opening extension operation. This process will be hereinafter referred to as "command processing".

[0039] 1-3. Specific processes executed in the display system Figure 8 is a flowchart of the routine executed in the display system of Embodiment 1. This routine is repeatedly executed by the processor 40 of the management server 30 at a predetermined control cycle. This routine also represents a part of the display method for displaying the status of elevator users in the display system 100.

[0040] In step S100, the imaging data captured by the imaging device 20 is acquired through an acquisition process. The acquired imaging data is temporarily stored in the data 56 area of ​​the memory 50.

[0041] In step S102, user information is acquired through analysis processing. Typically, the user attributes and congestion level within the elevator car 2 are analyzed by applying known image analysis processing to the image data acquired through the acquisition process. The analyzed attributes and congestion level are temporarily stored as user information in the data 56 area of ​​memory 50.

[0042] In step S104, it is determined whether there is one or more passengers inside the car 2. Here, the presence or absence of passengers inside the car 2 is determined based on the passenger information obtained through the analysis process. Alternatively, if a weighing device for measuring the load capacity of the car 2 is provided, the presence or absence of passengers inside the car 2 may be determined based on the measured value of the weighing device. Alternatively, if a sensor such as an infrared sensor for detecting the presence or absence of objects inside the car 2 is provided, the presence or absence of passengers inside the car 2 may be determined based on the signal from the sensor. If the determination is successful, the process proceeds to step S106. On the other hand, if the determination is unsuccessful, it is determined that there is no need to display the situation inside the car 2, and the process returns to step S100.

[0043] In step S106, it is determined whether the user attributes in cart 2 have been analyzed. If the determination is unsuccessful, it is determined that there is no need to display the status of cart 2, and the process returns to step S100. On the other hand, if the determination is successful, the process proceeds to step S108.

[0044] In step S108, an illustration image is generated based on user information. Here, the image generation process is executed to generate an illustration image that reflects the user's status in cart 2, including the user's attributes and the degree of congestion in cart 2, in an overview view.

[0045] Once the processing in step S108 is complete, the process proceeds to step S110. In step S110, prior to the arrival of the elevator car 2 at the landing 4, the illustration image generated by the image generation process is displayed in the air by the aerial display device 10 installed at the landing 4.

[0046] Once the processing in step S110 is complete, the process proceeds to step S112. In step S112, it is determined whether a door-open extension operation is required. Here, a determination process is executed to determine whether the user's attributes included in the user information include an attribute that requires consideration of the door-open time. If the determination is not successful, the door-open extension operation is not performed and this routine terminates. On the other hand, if the determination is successful, it is determined that a door-open extension operation is required, and the process proceeds to step S114.

[0047] In step S114, command processing is performed and an operation command for extending the door opening position is transmitted to the door opening / closing control device 22. The door opening / closing control device 22 executes the door opening / closing position extension operation according to the received operation command.

[0048] According to the display system 100 described above, an illustrated image showing an overhead view of the passengers inside the elevator car 2 is displayed in the air above the boarding area 4 prior to the arrival of the elevator car 2. This allows passengers waiting to board at boarding area 4 to be easily informed of the situation inside the elevator car 2 prior to its arrival, using an aerial image with excellent design and visibility. Furthermore, since the aerial image is displayed in the space of boarding area 4, it is possible to inform passengers who are in positions where they cannot see the walls of boarding area 4 about the situation inside the elevator car 2. In addition, because the aerial image of the illustrated image is an overhead view of the passengers inside the elevator car 2, it is easy to intuitively recognize the situation of the passengers inside the elevator car 2.

[0049] Furthermore, since the illustrations visually represent the attributes of the passengers inside car 2, passengers who view the aerial image will have time to decide in advance whether or not to take precautions for the passengers inside car 2 and act accordingly. In addition, since the illustrations visually represent the degree of congestion inside car 2, passengers who view the aerial image will be able to decide in advance whether or not to board car 2 based on its congestion level.

[0050] 1-4. Variations The display system 100 of Embodiment 1 may adopt the following modified form.

[0051] 1-4-1. Hardware resources of information processing equipment

[0052] Figure 9 shows a modified example of the hardware resources of a management server as an information processing device. In the example shown in Figure 9, the management server 30 as an information processing device includes, for example, a processor 40, memory 50, and a processing circuit 72 including dedicated hardware 70. Figure 9 shows an example in which some of the functions of the management server 30 are realized by the dedicated hardware 70. All of the functions of the management server 30 may also be realized by the dedicated hardware 70. The dedicated hardware 70 can be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. This modified example can also be applied to the display system of Embodiment 2 described later.

[0053] 1-4-2. Functional configuration of the management server 30 Some of the functions of the management server 30 may be installed in other devices such as the imaging device 20, the aerial display device 10, and the door opening / closing control device 22. This modification can also be applied to the display system of Embodiment 2, which will be described later.

[0054] 1-4-3.Aerial display device There are no limitations on the placement of the aerial display device 10 at boarding area 4. Figure 10 shows a modified example of the placement of the aerial display device at the boarding area. In this modified example, the aerial display device 10 is installed on the wall above the boarding door 6. With this placement of the aerial display device 10, the aerial image is displayed at a position higher than the boarding door 6, thus improving visibility for users around the boarding door 6.

[0055] 1-4-4. Door Open Extension Operation The functional configuration and processing performed in relation to the door opening extension operation are not mandatory.

[0056] 1-4-5. Image generation process In the image generation process, the process by which the image generation unit 43 generates the illustration image is not limited to the method described above. That is, in the modified image generation process, the extraction unit 434 of the image generation unit 43 extracts an image of the inside of the cart viewed from above with a transparent view, and user illustrations corresponding to the user's attributes, from the illustration DB 54. The extraction unit 434 then generates an illustration image by combining one or more user illustrations with the cart image according to the degree of congestion. This process also makes it possible to generate an illustration image that reflects the attributes of the users in the cart 2 and the degree of congestion inside the cart 2.

[0057] Furthermore, adding color according to the level of congestion is not mandatory in the image generation process. For example, instead of color, highlighting features such as textures may be added to the illustration image during the image generation process. In addition, the color of the illustration image may be changed according to the number of elevator car calls registered at each boarding area 4 and the number of times the destination floor registration button has been pressed inside elevator car 2.

[0058] 2. Embodiment 2. In Embodiment 2, the differences from the example disclosed in Embodiment 1's display system 100 will be described in particular detail. For features not described in Embodiment 2, any of the features of the example of the display system 100 disclosed in Embodiment 1 may be adopted.

[0059] 2-1. Features of the elevator display system in Embodiment 2 Figure 11 shows an example of the configuration of the elevator display system in Embodiment 2. The display system 100 in Embodiment 2 has the same configuration as the display system in Embodiment 1, except for the installation locations of the aerial display device 10 and the imaging device 20.

[0060] The imaging device 20 is a camera installed in the elevator landing 4. The imaging device 20 periodically captures and outputs images of users waiting to board the elevator in the landing 4. There are no limitations on the type, number, or installation location of the imaging device 20 in the landing 4.

[0061] The aerial display device 10 is installed on the wall inside the elevator car 2 and displays an illustrated image in the air facing the landing 4. In the example shown in Figure 11, the aerial display device 10 is installed on the side of the front of the elevator car 2 where the elevator car door 3 is located. The aerial display device 10 is not limited to any specific location as long as it can display an aerial image at a position visible to passengers inside the elevator car 2. Figure 12 shows a modified example of the arrangement of the aerial display device inside the elevator car. In this modified example, the aerial display device 10 is installed above the side wall inside the elevator car 2. With this arrangement of the aerial display device 10, the aerial image is displayed at a higher position inside the elevator car 2, thus improving visibility for passengers inside the elevator car 2.

[0062] In the analysis process, the management server 30 analyzes the attributes of users around the boarding door 6 of boarding 4, which is the area to be analyzed, and the degree of congestion at boarding 4, based on the imaging data acquired from the imaging device 20. In the image generation process, the management server 30 generates an illustration image to be displayed in the air by the aerial display device 10 based on the user information analyzed by the analysis process. The illustration image here is, for example, an illustration that depicts the situation of users waiting to board at boarding 4, showing the attributes of users around the boarding door 6 of boarding 4 and the degree of congestion as an overhead view.

[0063] Figure 13 is an example of illustrated images corresponding to user attributes. Figures (A) through (D) show an overview of the situation of users at boarding area 4, categorized by user attribute. Figure (A) is an illustration of a person, illustrating an adult and a child waiting to board. Figure (B) is an illustration of a user using a wheelchair or stroller waiting to board. Figure (C) is an illustration of a user using a trolley waiting to board. And Figure (D) is an illustration of a self-propelled robot waiting to board.

[0064] Figure 14 is an example of an illustrated image that further reflects the degree of congestion in addition to the user attributes. The extraction unit 434 generates an illustrated image by combining one or more illustrations extracted from the illustration DB 54 according to the degree of congestion. Figures (A) to (C) in Figure 14 illustrate an overhead view of the inside of the elevator car when the passengers at boarding area 4 are people and the degree of congestion is low, medium, and high.

[0065] According to the display system 100 described above, an illustrated image showing an overview of the situation of passengers at boarding area 4 is displayed in the air inside the car 2 prior to its arrival at boarding area 4. This allows passengers inside the car 2 to be visually informed of the situation at boarding area 4 in advance.
