Description

[Technical Field]

[0001] The present invention relates to a display device or the like that is installed in a building in which inter-floor movement devices such as elevators or escalators are provided at multiple locations. [Background technology]

[0002] For example, buildings such as large-scale retail stores often have both elevators and escalators. In such cases, whether it is faster to use the elevator or the escalator to reach the destination floor varies depending on factors such as congestion. In response to this, for example, Patent Document 1 proposes a display device that calculates predicted arrival times for both the elevator and the escalator and displays recommended transportation methods. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-208773 Summary of the Invention [Problem to be solved by the invention]

[0004] The display device disclosed in Patent Document 1 presents information about recommended transportation methods to users by displaying a message such as, "Customers traveling from floor * to floor * should use the escalator." However, with this information, users who are heading to floors not displayed cannot know which transportation method is preferable. Furthermore, users cannot know the estimated time of arrival at the destination floor.

[0005] One aspect of the present invention aims to provide a display device that displays information that allows a user to easily recognize which inter-floor movement device to use depending on the user's destination floor. [Means for solving the problem]

[0006] In order to solve the above problems, a display device according to a first aspect of the present invention is a display device installed in a building in which inter-floor movement devices such as elevators or escalators are installed at multiple locations, and comprises: an operation status acquisition unit that acquires the operation status of the inter-floor movement devices; a travel time calculation unit that calculates, for each inter-floor movement device, the estimated travel time required to travel from the location where the display device is installed to all floors accessible by the inter-floor movement device according to the operation status; a selection unit that selects, for each of all of the floors, the inter-floor movement device recommended according to the estimated travel time; and a display control unit that displays, on the display unit, the inter-floor movement device selected by the selection unit and the estimated travel time or estimated arrival time corresponding to the inter-floor movement device for each of the floors.

[0007] According to the above configuration, for all floors accessible by inter-floor transportation devices, the recommended inter-floor transportation device according to the estimated travel time and the estimated travel time or estimated arrival time are displayed, thereby enabling the user to easily recognize which inter-floor transportation device to use according to their destination floor.

[0008] A display device according to aspect 2 of the present invention may be configured such that, in aspect 1 above, the selection unit recognizes the adjusted predicted travel time as the predicted travel time when the inter-floor movement device is the escalator, and selects the recommended inter-floor movement device.

[0009] With elevators, the actual travel time is likely to be longer than the estimated travel time due to additional stops, extended boarding and disembarking times, etc. On the other hand, with escalators, the error in the estimated travel time is relatively small. Therefore, with the above configuration, it is possible to increase the likelihood that an escalator with a small error in the estimated travel time will be recommended.

[0010] A display device according to aspect 3 of the present invention may be configured such that, in aspect 1 or 2 above, the travel time calculation unit calculates the predicted travel time taking into account the possibility of additional stopping floors and fluctuations in boarding and disembarking times when the inter-floor movement device is the elevator.

[0011] According to the above configuration, the estimated travel time is calculated taking into account factors that cause fluctuations in the estimated elevator travel time, such as the possibility of additional stopping floors and fluctuations in boarding and disembarking times, thereby improving the accuracy of the estimated elevator travel time.

[0012] The display device according to aspect 4 of the present invention, in any of aspects 1 to 3 above, may further include an operation detection unit that detects an operation on a direction selection call button provided at the elevator landing, and if, during a period in which the operation detection unit detects that the direction selection call button is pressed, there is a floor among the floors belonging to the selected direction for which the selection unit selects an inter-floor movement device other than the elevator, the display control unit may be configured to display information indicating that an inter-floor movement device other than the elevator is recommended for that floor.

[0013] According to the above configuration, when a user presses a directional call button, the user can recognize that it would be better to use a different inter-floor transfer device depending on the destination floor. This increases the likelihood that the user will cancel the directional call, thereby improving elevator utilization efficiency.

[0014] A display device according to aspect 5 of the present invention may be configured such that, in aspect 4 above, the display control unit displays, for a floor for which the selection unit selects an inter-floor movement device different from the elevator, both the estimated travel time or estimated arrival time by the elevator and the estimated travel time or estimated arrival time by the inter-floor movement device different from the elevator.

[0015] According to the above configuration, if it is preferable for a user to use a different inter-floor transfer device, the user can check the extent to which the expected travel time or expected arrival time differs, thereby further increasing the likelihood that the user will cancel the directional call.

[0016] A display control program according to a sixth aspect of the present invention is a display control program for causing a computer to function as the display device of any one of the first to fifth aspects, and is a display control program for causing a computer to function as each of the above units.

[0017] The display device according to each aspect of the present invention may be realized by a computer. In this case, the display control program for the display device that causes the computer to operate as each part (software element) of the display device to realize the display device, and the computer-readable recording medium on which the program is recorded, also fall within the scope of the present invention. [Effects of the Invention]

[0018] According to one aspect of the present invention, it is possible to display information that enables a user to easily recognize which inter-floor movement device to use depending on the user's destination floor. [Brief explanation of the drawings]

[0020] [Embodiment 1] An embodiment of the present invention will be described in detail below. Fig. 1 is a block diagram showing the configuration of a main part of a display system 100A in this embodiment. As shown in Fig. 1, the display system 100A includes an elevator 1, an escalator 2, and a display device 10A.

[0021] The elevator 1 and the escalator 2 are installed in the same building. In this embodiment, as an example, a configuration will be described in which users of the elevator 1 and the escalator 2 can move to each of the first to tenth floors by the elevator 1 and the escalator 2, respectively.

[0022] The elevator 1 outputs the operation status of the elevator 1 to the display device 10A. The operation status of the elevator 1 includes at least the car, operation route, and scheduled stopping floors of the elevator 1. The elevator 1 outputs the operation status to the display device 10A every time the operation status changes.

[0023] The escalator 2 outputs the operation status of the escalator 2 to the display device 10A. The operation status of the escalator 2 includes the degree of congestion of the escalator 2. The degree of congestion of the escalator 2 may be determined from the load on a motor (not shown) that drives the escalator 2, or may be determined by image recognition of an image of the escalator 2. The escalator 2 outputs the operation status to the display device 10A every time the operation status changes.

[0024] The display device 10A is installed at a landing on each floor of the elevator 1. In this embodiment, a landing for the elevator 1 is provided on each of the first to tenth floors.

[0025] As shown in FIG. 1, the display device 10A includes a display unit 11, a storage unit 12, and a control unit 20A.

[0026] The display unit 11 performs display based on instructions from a display control unit 24A, which will be described later. The display unit 11 may be, for example, a display such as a liquid crystal display. FIG. 2 is a diagram showing the vicinity of the elevator hall of the elevator 1 where the display unit 11 is installed. As shown in FIG. 2, the display unit 11 is provided at the elevator hall of the elevator 1 on each floor. Note that FIG. 2 shows an example in which the display unit 11 is installed above the direction selection call button 3 that a user uses to call a car of the elevator 1.

[0027] The memory unit 12 stores various data used by the display device 10A. The memory unit 12 stores data used by a travel time calculation unit 22A (described later) to calculate an expected travel time. For example, the memory unit 12 stores the time required for the elevator 1 car to travel between floors. The memory unit 12 also stores the time required for the escalator 2 to travel between floors. The memory unit 12 also stores the transfer time for the escalator 2 at each floor according to the congestion level of the escalator 2.

[0028] The control unit 20A controls each unit of the display device 10A. The control unit 20A includes an operation status acquisition unit 21, a travel time calculation unit 22A, a selection unit 23, and a display control unit 24A.

[0029] The operation status acquisition unit 21 acquires the operation status of the elevator 1 from the elevator 1. The operation status acquisition unit 21 also acquires the operation status of the escalator 2 from the escalator 2.

[0030] The travel time calculation unit 22A calculates the expected travel time required to travel from the floor where the display device 10A is installed to all floors accessible by the elevator 1 or the escalator 2, for each of the elevator 1 and the escalator 2. The expected travel time is the travel time expected to be required to travel from the time of calculation to the destination floor. Below, the methods for calculating the expected travel time for each of the elevator 1 and the escalator 2 will be described in detail.

[0031] First, a method for calculating the above-mentioned estimated travel time for the elevator 1 by the travel time calculation unit 22A will be described. The travel time calculation unit 22A calculates the estimated travel time for the elevator 1 based on the operation status of the elevator 1 acquired by the operation status acquisition unit 21. Specifically, the travel time calculation unit 22A first acquires floor information on the location of the car of the elevator 1 at the time of calculation and floor information on the floors at which the car of the elevator 1 is scheduled to stop, from the operation status of the elevator 1 acquired by the operation status acquisition unit 21. Next, based on the acquired floor information, the travel time calculation unit 22A calculates, as the above-mentioned estimated travel time, the sum of the travel time of the car of the elevator 1 on a travel route that runs from the floor on which the car of the elevator 1 is located at the time of calculation to each floor via the floor on which the display device 10A is installed, and the stop time of the car of the elevator 1 on the travel route for passengers to get on and off.

[0032] A specific example will be described with reference to FIG. 3. FIG. 3 is a diagram illustrating a method for calculating the above-mentioned expected travel time for the elevator 1. Here, it is assumed that the operation status acquisition unit 21 has acquired, as shown in FIG. 3, that the car of the elevator 1 is located on the 9th floor at the time of calculation, and that the car will then stop at the 10th and 8th floors and travel to the 4th floor, as the operation status of the elevator 1. In this case, as an example, a method will be described in which the travel time calculation unit 22A of the display device 10A installed on the 10th floor calculates the expected travel time required for the elevator 1 to travel from the 10th floor to the 4th floor. In this case, the travel time calculation unit 22A calculates, as the travel time, the sum of the travel time from the 9th floor to the 10th floor, the travel time from the 10th floor to the 8th floor, and the travel time from the 8th floor to the 4th floor. The travel time for each section is stored in the storage unit 12. In addition, the travel time calculation unit 22A calculates, as the stop time, the sum of the stop times at the 10th floor, the 8th floor, and the 4th floor. The stop time at each floor is set in advance and stored in the storage unit 12. For example, the stop time at each floor may be set to 5 seconds for a stop for a normal call and 10 seconds for a stop for a wheelchair call. Then, the travel time calculation unit 22A calculates the estimated travel time for the elevator 1 by adding the calculated running time and stop time.

[0033] Next, a method for calculating the above-mentioned expected travel time for the escalator 2 will be described. The travel time calculation unit 22A calculates the expected travel time for the escalator 2 based on the operation status of the escalator 2 acquired by the operation status acquisition unit 21. Specifically, the travel time calculation unit 22A first acquires the congestion level of the escalator 2 from the operation status of the escalator 2 acquired by the operation status acquisition unit 21. Next, based on the acquired congestion level, the travel time calculation unit 22A calculates, as the above-mentioned expected travel time, the sum of the travel time of the escalator 2 from the floor on which the display device 10A is installed to each floor and the transfer time required to change escalators at each floor on the travel route.

[0034] A specific example will be described with reference to FIG. 4. FIG. 4 is a diagram illustrating a method for calculating the above-mentioned expected travel time for the escalator 2. Here, a method will be described in which the travel time calculation unit 22A of the display device 10A installed on the 10th floor calculates the expected travel time required for a user to travel from the 10th floor to the 4th floor by the escalator 2. In this case, the travel time calculation unit 22A calculates, from the storage unit 12, the travel time of the escalator 2 required for a user to travel from the 10th floor where the user boards the escalator 2 to the 4th floor, as the travel time. Furthermore, the travel time calculation unit 22A calculates, as the transfer time, the transfer time required to change escalators on each floor from the 10th floor to the 4th floor, based on the congestion level of the escalator 2 acquired by the operation status acquisition unit 21. The transfer time on the 10th floor may include the travel time from the elevator 1 landing where the display device 10A is installed to the escalator 2 landing on the 10th floor. Then, the travel time calculation unit 22A calculates the estimated travel time for the escalator 2 by adding the calculated travel time and the transfer time.

[0035] The selection unit 23 selects a recommended inter-floor movement device in accordance with the expected travel time calculated by the travel time calculation unit 22A for each of all floors that can be reached from the floor on which the display device 10A is installed by the elevator 1 or the escalator 2. In this embodiment, the selection unit 23 selects, for each floor, the inter-floor movement device, either the elevator 1 or the escalator 2, that has the shorter expected travel time calculated by the travel time calculation unit 22A, as the recommended inter-floor movement device.

[0036] The display control unit 24A displays on the display unit 11, for each of all floors that can be reached by elevator 1 or escalator 2 from the floor on which the display device 10A is installed, the inter-floor movement device selected by the selection unit 23 and the estimated movement time calculated by the movement time calculation unit 22A corresponding to that inter-floor movement device.

[0037] FIG. 5 is a diagram showing a display example of the display unit 11 of the display device 10A installed on the fourth floor. In this display example, the travel time calculation unit 22A calculates that the estimated travel time from the fourth floor is shorter when traveling to the second, third, and fifth floors by using the escalator 2, and shorter when traveling to the other floors by using the elevator 1. As shown in FIG. 5, the display control unit 24A displays, on the display unit 11, the inter-floor movement device with the shortest estimated travel time for each of the first to third and fifth to tenth floors accessible from the fourth floor, and the estimated travel time when using the inter-floor movement device. Note that in this example, the display control unit 24A is configured to display the estimated travel time on the display unit 11, but the present invention is not limited to this. In one aspect of the present invention, the display control unit 24A may display, instead of the estimated travel time, the estimated arrival time, which is the time when the user will arrive at each floor when using the inter-floor movement device selected by the selection unit 23.

[0038] Fig. 6 is a diagram showing another example of display on the display unit 11 of the display device 10A installed on the fourth floor. As shown in Fig. 6, the display control unit 24A may display, as the predicted travel time, on the display unit 11, a time obtained by correcting the predicted travel time calculated by the travel time calculation unit 22A so that the time is in 30-second increments.

[0039] As described above, the display device 10A in this embodiment displays, for each of all floors that can be reached by elevator 1 or escalator 2 from the floor on which the display device 10A is installed, the inter-floor movement device selected by the selection unit 23 and the estimated travel time when using that inter-floor movement device.

[0040] According to this configuration, the inter-floor transfer device that provides the shortest expected travel time and the expected travel time are displayed for all floors that can be reached by elevator 1 or escalator 2. Therefore, users can easily recognize which inter-floor transfer device they should use depending on their destination floor.

[0041] In the display device 10A of this embodiment, the selection unit 23 is configured to select, as the recommended inter-floor transportation device, either the elevator 1 or the escalator 2, whichever has the shorter expected travel time calculated by the travel time calculation unit 22A, but the display device of the present invention is not limited to this. In a display device of one aspect of the present invention, the selection unit 23 may be configured to recognize, for an inter-floor transportation device such as the escalator 2, the adjusted expected travel time obtained by subtracting a predetermined time (for example, 10 seconds) from the expected travel time calculated by the travel time calculation unit 22A, and select the recommended inter-floor transportation device.

[0042] Here, with elevators, there is a high possibility that the actual travel time will be longer than the estimated travel time due to additional floors to stop at and extended boarding and disembarking times. On the other hand, with escalators, the error in the estimated travel time is relatively small. Therefore, with the above configuration, it is possible to increase the possibility that escalator 2, which has a small error in the estimated travel time, will be recommended.

[0043] In this embodiment, the display device 10A is configured to be installed at the elevator 1 landing on each floor, but the location where the display device 10A of the present invention is installed is not limited to this. In one aspect of the present invention, the display device 10A may be installed, for example, near an entrance or exit of a building or near the location where a floor map is installed. In this case, the travel time calculation unit 22A calculates the expected travel time by taking into account the travel time from the location where the display device 10A is installed to the elevator 1 and the travel time from the location where the display device 10A is installed to the escalator 2.

[0044] In addition, in this embodiment, the display device 10A is intended for two inter-floor movement devices, one elevator 1 and one escalator, but the display device 10A of the present invention is not limited to this. The display device 10A of one aspect of the present invention may be intended for another elevator instead of the escalator 2, in other words, for only two elevators, or may be intended for another escalator instead of the elevator 1, in other words, for only two escalators.

[0045] Furthermore, the display device 10A according to one embodiment of the present invention may be configured to handle three or more inter-floor movement devices (for example, two elevators and one escalator, or three elevators). In this case, the travel time calculation unit 22A calculates the estimated travel time for each of the three or more inter-floor movement devices for all floors accessible from the location where the display device 10A is installed. The display control unit 24A may then cause the display unit 11 to display the inter-floor movement device with the shortest estimated travel time among the three or more inter-floor movement devices, and the estimated travel time corresponding to that inter-floor movement device. In this case, it is preferable that the display control unit 24A display on the display unit 11 a display that identifies the location where the inter-floor movement device with the shortest estimated travel time is installed.

[0046] Furthermore, in the display device 10A according to one aspect of the present invention, the display control unit 24A may cause the display unit 11 to display, in addition to the inter-floor movement device selected by the selection unit 23 and the estimated travel time calculated by the travel time calculation unit 22A corresponding to that inter-floor movement device, inter-floor movement devices not selected by the selection unit 23 and the estimated travel time calculated by the travel time calculation unit 22A corresponding to that inter-floor movement device. In this case, it is preferable that the inter-floor movement device selected by the selection unit 23 and the estimated travel time calculated by the travel time calculation unit 22A corresponding to that inter-floor movement device are displayed in an emphasized manner.

[0047] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0048] Fig. 7 is a block diagram showing the configuration of the main parts of a display system 100B according to this embodiment. As shown in Fig. 7, the display system 100B includes a display device 10B instead of the display device 10A according to the first embodiment. The display device 10B includes a control unit 20B instead of the control unit 20A according to the first embodiment. The control unit 20B includes a travel time calculation unit 22B instead of the travel time calculation unit 22A according to the first embodiment.

[0049] When the inter-floor movement device is elevator 1, travel time calculation unit 22B calculates the expected travel time required to move from the floor where display device 10B is installed to all floors accessible by elevator 1, taking into account the possibility of additional stopping floors and fluctuations in boarding and disembarking times.

[0050] For example, the travel time calculation unit 22B may calculate the estimated travel time by adding the following times (A) and (B) to the estimated travel time calculated by the travel time calculation unit 22A in the first embodiment.

[0051] (A) The time corresponding to the number of floors at which the elevator 1 is not scheduled to stop on the route from the floor where the elevator car 1 is located at the time of calculation to each floor via the floor where the display device 10B is installed. (B) The time corresponding to the number of floors at which the elevator 1 is scheduled to stop on the route from the floor where the elevator car is located at the time of calculation to each floor via the floor where the display device 10B is installed.

[0052] The above-mentioned time (A) is a time that takes into consideration the possibility of additional floor stops. Since the greater the number of floors at which the train is not scheduled to stop, the greater the possibility of additional floor stops, it is preferable to lengthen the above-mentioned time (A) according to the number of floors at which the train is not scheduled to stop. For example, the travel time calculation unit 22B may calculate the above-mentioned time (A) by multiplying the number of floors at which the train is not scheduled to stop by a predetermined time.

[0053] The time (B) above is a time that takes into consideration fluctuations in boarding and alighting times due to instructions to open or close the doors of the car. The travel time calculation unit 22B may calculate the time (B) above by multiplying the number of floors where the car is scheduled to stop by an error time (for example, -3 seconds to 3 seconds).

[0054] According to the above configuration, the expected travel time is calculated taking into account factors that cause fluctuations in the expected travel time of elevator 1, such as the possibility of additional stopping floors and fluctuations in boarding and disembarking times, thereby improving the accuracy of the expected travel time of elevator 1.

[0055] [Embodiment 3] Another embodiment of the present invention will be described below. Fig. 8 is a block diagram showing the main configuration of a display system 100C according to this embodiment. As shown in Fig. 8, the display system 100C includes a display device 10C instead of the display device 10A in the first embodiment. The display device 10C includes a control unit 20C instead of the control unit 20A in the first embodiment. The control unit 20C includes a display control unit 24B instead of the display control unit 24A in the first embodiment, and also includes an operation detection unit 25.

[0056] The operation detection unit 25 detects an operation by a user on a direction selection call button 3 provided at the elevator hall of the elevator 1 where the display device 10C is installed.

[0057] During the period when the operation detection unit 25 detects that the direction selection call button 3 is pressed, if there is a floor belonging to the selected direction for which the selection unit 23 selects an inter-floor movement device (i.e., escalator 2) other than the elevator 1 (in the following explanation, this case will be described as case A), the display control unit 24B displays on the display unit 11 a display different from the display displayed on the display unit 11 by the display control unit 24A in embodiment 1.

[0058] Specifically, in case A, the display control unit 24B displays information indicating that the escalator 2 is recommended for the floor selected by the selection unit 23 among the floors belonging to the selected direction. For example, the display control unit 24B may cause the display unit 11 to emphasize (for example, by changing the color or displaying it larger) the display of the escalator 2 selected by the selection unit 23 among the floors belonging to the selected direction. This allows the user to recognize that, when pressing the direction selection call button 3, it may be preferable to use a different inter-floor movement device (i.e., the escalator 2) depending on the destination floor. This increases the likelihood that the user will cancel the direction selection call, thereby improving the utilization efficiency of the elevator 1.

[0059] Alternatively, as shown in Fig. 9, the display control unit 24B may display both the estimated travel time by elevator 1 and the estimated travel time by escalator 2 for floors (2nd and 3rd floors) for which the selection unit 23 selects escalator 2 among the floors belonging to the selected direction. This allows the user to confirm how much the estimated travel time differs when it is preferable to use escalator 2. This further increases the likelihood that the user will cancel the direction-selection call.

[0060] [Software implementation example] The functions of the display devices 10A to 10C (hereinafter referred to as "devices") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in the control units 20A to 20C).

[0061] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0062] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0063] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0064] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
