Description

The present invention relates to an elevator passenger guidance system and method for guiding passengers in an elevator hall.

Large buildings typically have multiple elevator landings in one elevator hall. In these cases, a system may be used to guide passengers to the landing to prevent them from getting lost or to shorten the time it takes to reach their destination floor. One such passenger guidance system is disclosed in Patent Document 1, for example. Patent Document 1 discloses technology that projects images onto the floor of the elevator hall or landing to show passengers where to wait and the route they should take.

Japanese Patent Application Laid-Open No. 2015-218015

However, the projected image may be blocked by a passenger's body or luggage, making it impossible to understand the image's contents. Furthermore, passengers may be looking at their smartphones or other devices and fail to notice the projected image, or may notice it late. In such cases, passengers may not be able to board the elevator indicated by the guidance system, or the elevator may be delayed in departing, causing other passengers to take longer to reach their destination floor.

The object of the present invention is to guide passengers by changing at least one of the illuminance, hue, or saturation of the lighting in the elevator hall.

To solve the above problem, the present invention provides a system for guiding passengers in an elevator hall with multiple landings to one of the multiple landings, comprising: a plurality of lighting devices that irradiate visible light onto each of multiple areas when the surface of the elevator hall is divided into multiple regions; and a control device that generates and outputs control information for each of the plurality of lighting devices. The control device identifies two or more taxiway areas from the multiple areas that will serve as taxiways for guiding the passengers from the entrance of the elevator hall to one of the landings, and identifies two or more taxiway lighting devices from the plurality of lighting devices that respectively illuminate the two or more taxiway areas. The two or more taxiway lighting devices variably control at least one of the illuminance, hue, or saturation in the two or more taxiway areas in multiple stages based on the control information.

According to the present invention, passengers can be guided by changing at least one of the illuminance, hue, or saturation of the lighting in the elevator hall.

Other issues, configurations, and advantages will become clear from the description of the embodiments of the invention below.

[0022] FIG. 1 is a schematic configuration diagram showing an example of the configuration of an elevator to which an elevator operation control system according to a first embodiment of the present invention is applied.

The elevator operation control system according to the embodiment will be described below with reference to Figures 1 to 4. Note that common components in each figure are given the same reference numerals. Furthermore, when there are multiple components with the same or similar functions, they may be described using the same reference numerals with different subscripts. Furthermore, when there is no need to distinguish between these multiple components, the subscripts may be omitted.

In this embodiment, multiple lighting devices respectively illuminating multiple areas on the surface of the elevator hall are set to their preparatory lighting during the preparation stage, illuminating the entire hall with the minimum necessary illuminance. Then, lighting devices illuminating waiting areas for passengers who have registered their destination floors are set to a first-level lighting that is different from the preparation stage. The lighting devices illuminating guidance positions for guiding passengers moving from the elevator hall entrance to the waiting area are sequentially updated to second-level lighting. The lighting devices illuminating passengers in the waiting area who will board the elevator car to the landing are changed to third-level lighting in accordance with the arrival of the elevator, and the lighting devices illuminating the guideway to the landing are changed to fourth-level lighting.

1 is a plan view showing an elevator hall of an elevator to which an elevator passenger guidance system according to a first embodiment of the present invention is applied. In FIG. 1, the elevator hall 1 is configured as an open space adjacent to a shaft (not shown) through which multiple cars 5a, 5b, and 5c ascend and descend. The elevator hall 1 is formed with an entrance 2 for entering the elevator hall 1 and multiple landings 4a, 4b, and 4c for boarding the multiple cars 5a, 5b, and 5c. There may be multiple entrances 2, and the entrances 2 may be adjacent to an exit (not shown) through which passengers disembarking from cars 5 exit the elevator hall 1, or the exit may be separated from the entrance 2. Part of the landing 4 is configured with a door that opens and closes by the elevator. Passengers 6 enter the elevator car 5 through the door of landing 4.

A destination registration device 3 is installed near the entrance 2 of the elevator hall 1. The destination registration device 3 has the function of allowing passengers 6 to input the floor at which they wish to disembark (destination floor), or the function of communicating with an IC (Integrated Circuit) card or the like carried by passengers 6 to automatically register floors at which passengers 6 can disembark.

The elevator hall 1 is a rectangular plaza formed in a generally flat surface, and its surface is divided into multiple areas. The areas of the elevator hall 1 are, for example, an area showing multiple guide positions 41, 42, and 43 for guiding passengers 6; an area showing multiple waiting positions 31A, 32A, 32B, 32C, and 33A for passengers 6 to wait; and an area showing landing positions (guidance routes) for guiding passengers 6 from each waiting position to each landing 4a, 4b, and 4c, such as an area showing boarding position 52A for guiding passengers 6 from waiting position 32B to landing 4b. Each area of the elevator hall 1 is illuminated with illumination light (visible light) from multiple lighting devices (not shown) installed on the ceiling of the elevator hall 1.

The passenger guidance system of this embodiment does not need to be applied to elevator halls on all floors of a building; it may be applied only to elevator halls on floors where many passengers head to many destination floors, such as the main entrance. Furthermore, in elevator halls where the passenger guidance system of this embodiment does not apply, all that is required is a device for passengers to input the floor where they wish to disembark, or a device for inputting the direction of the floor where they wish to disembark, such as up or down. Additionally, there may be a device that notifies passengers of the car they should board.

2 is a schematic diagram showing the state in which multiple lighting devices installed on the ceiling of the elevator hall of an elevator to which the elevator passenger guidance system according to Example 1 of the present invention is applied are projected onto the elevator hall. In FIG. 2, multiple lighting devices 11 are arranged on the ceiling of the elevator hall 1, for example, along an imaginary grid-like axis, and are equally spaced from one another. Each lighting device 11 is configured with multiple types of light-emitting elements, for example, multiple light-emitting diodes (LEDs), as a light source. This light source is configured, for example, with red, blue, and green LEDs, and the light (visible light) from each LED is irradiated toward each area of the elevator hall 1. For example, of the multiple lighting devices 11, lighting devices 11a to 11c illuminate the areas indicating guidance positions 41 and 42, lighting devices 11e to 11i illuminate the areas indicating waiting positions 32A and 32B, and lighting device 11j illuminates the area indicating boarding position 52A.

In this case, each lighting device 11 individually and variably controls at least one of the illuminance, hue, and saturation in each region by, for example, controlling at least one of the luminance of the light source or the mixing ratio of the emitted color from the light source. Preferably, the illumination angle range is limited so that the illumination ranges of adjacent lighting devices 11 do not overlap. Here, illuminance refers to the brightness of the light illuminating the surface of the elevator hall 1, and is measured in lux. Hue refers to differences in color tone, such as red, blue, and green. Saturation refers to the degree of vividness of a color. As described below, this lighting device 11 may also serve as a lighting device that illuminates the elevator hall with an illuminance greater than the minimum required for people to walk through the elevator hall. Furthermore, each lighting device 11 can variably control the lightness (degree of color brightness) instead of the illuminance in each region.

Figure 3 is a block diagram showing an example configuration of an elevator operation control system according to Example 1 of the present invention. In Figure 3, the elevator operation control system includes a passenger guidance system 10 and an operation system 20. The passenger guidance system 10 is composed of multiple lighting devices 11, passenger detection devices 12, and guidance control devices 13, and is connected to the operation system 20. This operation system 20 is composed of a group management device 21, multiple destination registration devices 22, and multiple drive control devices 23.

Each destination registration device 22 includes at least one destination registration device 3 and is installed at the landing of each floor. It has the function of transmitting destination floor information indicating the destination floor entered by passengers at each floor landing to the group control device 21 via a network or transmission path (not shown). For example, a destination registration device 22 including a destination registration device 3 transmits destination floor information indicating the destination floor of a passenger 6 who has passed through entrance 2 to the group control device 21. Furthermore, when each destination registration device 22 receives information determined by the group control device 21 from the group control device 21, such as car number information indicating the number of the car that the passenger should board and departure order information indicating the departure order of the cars that the passenger should board, it has the function of displaying the received car number information and departure order information on a display screen and communicating them to the passenger.

Each drive control device 23 is configured as a device for driving a set of cars, including cars, drive devices, and safety systems. When each drive control device 23 receives stop floor information indicating the stop floors of each car (each car) from the group management device 21, it controls the movement of each car (each car) between landings based on the received stop floor information, and moves the car to the stop floor. At this time, each drive control device 23 transmits current location information indicating the current location of the car and passenger number information indicating the number of passengers in the car to the group management device 21 via a network or transmission path (not shown).

The group control device 21 determines which car passengers will board and which floors each car will stop at based on destination floor information from each destination registration device 22 and current location information and passenger count information from each drive control device 23. Based on these decisions, the group control device 21 generates stop floor information indicating the stop floors for each car (each car), car number information indicating the car number of each car, departure order information indicating the departure order of each car, and arrival timing information indicating the timing (scheduled time) at which each car 5 will arrive at the platform 4, and transmits the generated stop floor information to each drive control device 23, and transmits the generated car number information, departure order information, and arrival timing information to the guidance control device 13 via a network or transmission path (not shown).

At this time, the group control device 21 transmits destination floor information from each destination registration device 22 to the guidance control device 13. That is, the group control device 21 transmits (sends) group control information including destination floor information, car number information, departure order information, and arrival timing information to the guidance control device 13 via a network or transmission path (not shown). The group control device 21 receives destination floor information for passengers 6 who have passed through entrance 2 from a destination registration device 3 located near entrance 2, and based on the received destination floor information, determines the car 5 in which the passenger 6 who has passed through entrance 2 will board, and generates car number information, departure order information, and arrival timing information for the determined car 5.

The passenger detection device 12 detects each passenger in the elevator hall and, as a result of the detection, transmits passenger position information indicating the position of each passenger to the guidance control device 13 via a network or transmission path. In this case, the passenger detection device 12 is composed of, for example, one or more cameras and an image processing device. Each camera is located in an area where it can capture images of passengers in the elevator hall 1, and is placed, for example, on the wall or ceiling of the elevator hall 1.

The guidance control device 13 is configured as a control device that generates control information for each lighting device 11 to variably control at least one of the illuminance, hue, or saturation in each area of the elevator hall 1 based on group management information from the group control device 21 and passenger position information from the passenger detection device 12, and outputs the generated control information to each lighting device 11. When each lighting device 11 receives control information from the guidance control device 13, it controls at least one of the luminance of the light source or the mixing ratio of the emitted color produced by the light source based on the control information. As a result, at least one of the illuminance, hue, or saturation in each area of the elevator hall 1 is individually and variably controlled.

Here, based on destination floor information belonging to the group management information from the group management device 21 and passenger position information from the passenger detection device 12, the guidance control device 13 identifies two or more taxiway areas from the multiple areas that will serve as taxiways for guiding passengers 6 from the entrance 2 of the elevator hall 1 to one of the landings 4, and identifies two or more taxiway lighting devices from the multiple lighting devices 11 that will respectively illuminate the two or more taxiway areas. As control information for the two or more taxiway lighting devices, it generates multi-stage control information that changes at least one of the illuminance, hue, or saturation in the two or more taxiway areas in multiple stages. In this case, the guidance control device 13 sequentially changes the content of the multi-stage control information depending on the arrival timing or scheduled arrival time of the car 5 that passengers 6 are to board at the elevator hall 1. The two or more taxiway lighting devices variably control at least one of the illuminance, hue, or saturation in the two or more taxiway areas in multiple stages based on the amount of multi-stage control information.

Specifically, during the preparation stage, the guidance control device 13 first generates and outputs preparation stage control information for each of the multiple lighting devices 11, which sets the illuminance or hue or saturation of at least the illuminance in each area to the same value. For example, the guidance control device 13 generates preparation stage control information such that the illuminance of the entire surface of the elevator hall 1 (illuminance of all areas) is the lowest possible value that does not fall below the minimum illuminance specified by law, etc., and outputs the generated preparation stage control information to each lighting device 11. At this time, each lighting device 11 controls the brightness of each light source in accordance with the preparation stage control information, so that each area on the surface of the elevator hall 1 is illuminated with the same illuminance as preparation stage lighting.

Next, the guidance control device 13 executes the first stage of processing after the preparation stage, on the condition that it has generated and output preparation stage control information for each of the multiple lighting devices 11 during the preparation stage, which sets the illuminance, hue, or saturation of at least the illuminance in each area to be the same. For example, based on the destination floor information and car number information in the group management information, the guidance control device 13 identifies two or more guideway areas from the multiple areas that will serve as guideways for guiding passengers 6 from the entrance 2 of the elevator hall 1 to one landing 4, and identifies two or more guideway lighting devices (e.g., lighting devices 11a to 11j) from the multiple lighting devices 11 that will respectively illuminate the two or more guideway areas.

After this, when the guidance control device 13 recognizes that passenger 6 has appeared in the elevator hall 1 based on passenger position information from the passenger detection device 12, it identifies one or more first taxiway areas among the two or more taxiway areas that are connected to the entrance 2 of the elevator hall 1 and indicate the guidance positions 41, 42 of passenger 6, and generates and outputs first-stage control information whose control content differs from that of the preparation-stage control information to the lighting devices (first taxiway lighting devices) 11a, 11b, 11c, 11d that illuminate the identified one or more first taxiway areas.

Furthermore, based on passenger position information from the passenger detection device 12, the guidance control device 13 identifies a second taxiway area that is adjacent to the first taxiway area and indicates the waiting position 32A for the passenger 6, and generates and outputs first-stage control information whose control content differs from that of the preparation-stage control information to the lighting devices (second taxiway lighting devices) 11e, 11f that illuminate the identified second taxiway area.

At this time, lighting devices 11a, 11b, 11c, 11d, 11e, and 11f control the light emission state of each light source according to the first-stage control information, so that the first taxiway area indicating passenger 6 guidance positions 41 and 42 and the second taxiway area indicating passenger waiting position 32A are each illuminated with first-stage lighting, for example, with the same hue and saturation as the preparation stage lighting but with a higher illuminance than the preparation stage. The first-stage lighting may also be of a different hue or saturation than the preparation stage lighting but with an illuminance equal to or greater than that of the preparation stage. By changing the lighting at waiting position 32A from the preparation stage to the first stage, passengers 6 who have passed through entrance 2 can recognize waiting position 32A, their immediate destination.

Then, the guidance control device 13 generates second-stage control information, the control content of which differs from the first-stage control information, for the lighting devices 11a, 11b, 11c, and 11d that illuminate the first taxiway area indicating the passenger 6's guidance positions 41 and 42 as the second floor, and sequentially outputs the generated second-stage control information. At this time, the lighting devices 11a, 11b, 11c, and 11d sequentially control the light-emitting state of each light source in accordance with the second-stage control information, so that the first taxiway areas indicating the passenger 6's guidance positions 41 and 42 are sequentially illuminated with second-stage lighting, for example, with the same hue and saturation as the first-stage lighting but with a higher illuminance than the first-stage lighting.

In addition, the hue or saturation may be changed for each passenger to make it easier to distinguish between them when multiple passengers are heading to their respective waiting positions at the same time. By sequentially changing the lighting at guidance positions 41, 42 from the first level to the second level, passengers 6 can reach the waiting position 32A of the car 5 they are to board without getting lost simply by following guidance positions 41, 42, which change sequentially as they move forward. In addition, the guidance control device 13 can sequentially change the lighting by lighting devices 11a, 11b, 11c, and 11d from the first level to the second level based on passenger position information from the passenger detection device 12.

Next, when the guidance control device 13 receives group management information including arrival timing information, it determines a waiting position 32B for passenger 6 as a third step based on the arrival timing information and passenger position information (information for considering the passenger boarding order), and then, as a fourth step, determines a boarding position 52A for guiding passenger 6.

In the third stage, the guidance control device 13 generates and outputs third-stage control information, the control content of which differs from the second-stage control information, to the lighting devices (third-stage lighting devices) 11g, 11h, and 11i that illuminate the third taxiway area indicating the waiting position 32B for passengers 6, which is the landing-side waiting position. At this time, the lighting devices 11g, 11h, and 11i control the light-emitting state of each light source in accordance with the third-stage control information, so that the third taxiway area indicating the waiting position 32B for passengers 6 is illuminated with third-stage lighting, which, for example, is easily distinguishable from the first-stage lighting. The third-stage lighting may, for example, flash the lighting on the first floor, alternate between higher and lower illuminance than the first-stage lighting, or switch between two or more hues or saturations.

By changing the lighting at passenger 6's waiting position 32B from the preparation stage to the third stage, passenger 6 can recognize when it is time to head to hall 4, even if they are looking at their smartphone or other device, without having to stare at the images being projected. This allows passenger 6 to move smoothly, and is expected to shorten the arrival time not only for passenger 6 but for all passengers using the elevator.

Next, in the fourth stage, the guidance control device 13 generates and outputs fourth-stage control information, the control content of which differs from the third-stage control information, to the lighting device (fourth taxiway lighting device) 11j that illuminates the fourth taxiway area, which is an area adjacent to the waiting position 32B for the passenger 6 and indicates the boarding position 52A for the passenger 6. At this time, the lighting device 11j controls the light emission state of the light source in accordance with the fourth-stage control information, so that the fourth taxiway area indicating the boarding position 52A is illuminated with fourth-stage lighting, for example, with the same hue and saturation as the first-stage lighting and the same illuminance as the second-stage lighting.

By changing the lighting at boarding position 52A from the preparation stage to the fourth stage, passengers 6 can board the designated car 5 without getting lost, without having to remember the car number notified by the destination registration device 3.

The guidance control device 13 reduces the area in which the third level of lighting is applied in accordance with the movement of the passenger 6, based on passenger position information from the passenger detection device 12, and terminates the application of the fourth level of lighting. By performing this type of control, it is possible to prevent other passengers waiting nearby from accidentally boarding the vehicle.

When passengers for multiple destination floors are boarding a single elevator car at the same time, the guidance control device 13 first changes the light-emitting state of the lighting device 11 corresponding to the guidance position or waiting position where the passenger on the farthest destination floor is located from level 1 or level 2 to level 3, and also changes the lighting of the guidance position or waiting position where the passenger on the farthest destination floor is located from level 1 or level 2 to level 3. The guidance control device 13 then changes the light-emitting state of the lighting device 11 corresponding to the guidance position or waiting position where the passenger on the farthest destination floor is located to level 4, and also changes the lighting of the guidance position or waiting position where the passenger on the farthest destination floor is located to level 4.

At this time, the timing when this passenger has completed boarding is determined based on passenger position information from the passenger detection device 12, and when the passenger at the farthest destination floor has completed boarding, similar control is executed for the passenger at the next farthest destination floor. This control is executed sequentially for all passengers boarding the same elevator 5. By executing this type of control by the guidance control device 13, passengers who will disembark first board the elevator 5 later, so passengers closest to the elevator 5 entrance and exit disembark in order, thereby shortening the time the elevator 5 stops for passengers to disembark, and as a result, shortening the passenger arrival time.

Furthermore, when the passenger detection device 12 detects that passenger 6 has left a taxiway area belonging to the taxiway, the guidance control device 13 can generate and output auxiliary control information whose control content differs from the preparation stage control information through the fourth stage control information to the auxiliary lighting devices 11 that illuminate adjacent areas adjacent to two or more taxiway areas belonging to the taxiway. For example, when the passenger detection device 12 detects that passenger 6 is about to leave waiting position 32B, the guidance control device 13 can change the lighting by the lighting devices (auxiliary lighting devices) arranged around passenger 6's waiting position 32 from level 1 or 3 to level 5, and change the lighting around passenger 6 from level 1 or 3 to level 5 to issue a warning. This can prevent passenger 6 from boarding the wrong car 5 or failing to board the designated car 5, which could result in a longer arrival time for passenger 6 at his or her destination floor. This fifth level of illumination may be the same as the third level of illumination, or may be a distinguishable change in illumination relative to the third level of illumination.

Figure 4 is a schematic diagram showing an example of the configuration of an elevator to which the elevator operation control system according to Example 1 of the present invention is applied. In Figure 4, the elevator 40 includes a car 5 that moves up and down along a hoistway (not shown) to transport passengers, a hoist 42 around which a main rope 41 connected to the car 5 is wound, a counterweight 43 connected to the end of the main rope 41, and a brake 44 for maintaining the rotation of the hoist 42. The car 5 also includes a door 45. In this example, the hoist 42, brake 44, and door 45 are connected to the drive control device 23 via control lines. The drive control device 23 controls the operation of the hoist 42, brake 44, and door 45 via the control lines. Note that the elevator 40 is not limited to the type shown in Figure 4; the elevator operation control system according to this example can be applied to various types of elevators, such as a double-deck elevator with a two-story car 5 and a hydraulic elevator.

According to this embodiment, passengers can be guided by changing at least one of the illuminance, hue, and saturation of the lighting in the elevator hall. Furthermore, according to this embodiment, passengers can recognize the guideway, including the guidance position, waiting position, and boarding position, as well as the timing to board, by changes in the lighting around them, without having to intentionally look at projected images, etc. As a result, passengers can move from the entrance of the elevator hall to the elevator landing without getting lost. Furthermore, the time it takes passengers in the elevator car to reach the floor where they will disembark can be shortened.
