Description

Embodiments of the present invention relate to an elevator device and a display method.

Braille notation has long been known as a technology for visually impaired elevator users. However, this Braille notation is mainly for users with severe visual impairments such as total blindness, and the reality is that most people with visual impairments such as amblyopia cannot read Braille.

On the other hand, there are now elevators that provide audio guidance for arriving at each floor. However, many elderly visually impaired people tend to have hearing loss as well, and audio guidance is not necessarily sufficient consideration for visually impaired people.

In other words, Braille notation and voice guidance alone were insufficient as technology for visually impaired elevator users.

In addition, in recent elevators, display monitors are used to provide arrival guidance for each floor (landing floor display), etc., and the content of the display is independent of the user's position in the car. A position display device designed to make it easy to confirm has also been proposed.

For example, the elevator position display device disclosed in Patent Document 1 uses a rotatable display installed on the ceiling inside the car to ensure visibility of the landing floor display from all directions. It is something.

Japanese Patent Application Publication No. 2006-264870

However, in the past, the landing floor display was basically for healthy people (general users). had the disadvantage that it was difficult to confirm the displayed content.

Embodiments of the present invention can improve the difficulty in viewing the floor information display depending on the standing position in the car, and are particularly convenient for users with amblyopia and those suffering from hearing loss among visually impaired users. An object of the present invention is to provide an elevator device and a display method that can improve performance.

An embodiment of the present invention includes a display section that is provided on the inner ceiling portion of a car that is operated up and down between a plurality of floors and that can display various information, and a display section that is provided on the inner ceiling of a car that is operated up and down between a plurality of floors. a recognition unit that recognizes whether the person is a visually impaired person with amblyopia; and on the condition that the recognition unit recognizes a visually impaired person with amblyopia at the time of landing in the car, the information displayed on the display unit is configured to The vehicle is characterized by comprising a control unit that controls switching to floor information of the floor on which the car has landed, which has a font size that can be visually read by a person with a disability.

Another embodiment of the present invention is a display method for an elevator device, which indicates that when a car that is being operated up and down between a plurality of floors lands, the user of the car is a visually impaired person with amblyopia. Provided that the information is recognized by the recognition unit, the information displayed on the display unit installed on the inner ceiling of the car and capable of displaying various information can be visually read by the amblyopic and visually impaired person. The present invention is characterized in that the controller controls the information to be switched to the floor information of the floor on which the car has landed, which has a font size of 1.

This figure illustrates a car of the elevator system according to the first embodiment, in which (a) is a schematic diagram showing the inside of the car, and (b) is a schematic diagram showing the interior of the car. An enlarged view showing a display example. The schematic diagram showing the example of composition of an elevator device. The block diagram which illustrates the control system of an elevator apparatus. The figure which shows an example of the display on the ceiling monitor of an elevator apparatus. A flowchart illustrating a display method on a ceiling monitor of an elevator device. FIG. 3 is a schematic diagram showing the inside of a car of an elevator system according to a second embodiment of the present invention.

EMBODIMENT OF THE INVENTION Below, the elevator apparatus and display method based on embodiment of this invention are demonstrated with reference to drawings.

First form FIG. 1(a) is a schematic diagram showing the inside of a car (cage room) 15 of an elevator 1 according to a first form, and FIG. In addition, it is an enlarged view showing an example of display on a floor display (ceiling monitor) 23 as a display section.

Here, the inside of the car 15 is shown through the rear wall opposite to the front where the car door 17 is provided.

Inside the car 15, for example, as shown in FIG. 1(a), a car operation panel 19 is arranged on one inner wall portion of the front car door 17. The car operation panel 19 includes, for example, as shown in FIG. 3, a destination floor button 191, an announcement device 192 consisting of a speaker for providing voice guidance with floor information corresponding to the landing floor (arrival floor), etc. A human sensor (contact detection sensor) 194S that detects when the user 7, who is a passenger in the car 15, contacts the Braille marking section 194, and a door opening/closing button (not shown) are provided.

In FIG. 1(a), above the car operation panel 19, various guide information and advertising information about the inside of the building etc. are displayed, and when the car 15 lands on the floor, the landing floor of the car 15 is displayed. A display monitor (monitor device) 193 is installed. In order to ensure visibility, the display monitor 193 is desirably installed at a height of 1900 mm or more from the floor of the car 15, for example.

On the other hand, on the ceiling surface (inner ceiling part) of the car 15, in addition to a ceiling light 24 and an in-car camera 18 for monitoring, there is a floor indicator 23 as a ceiling monitor, for example, as shown in FIG. 1(b). is installed. This floor display 23 is for displaying various guide information, advertising information, etc., and for guiding the arrival floor of the car 15 by display when landing on the floor. This ensures good visibility so that the content displayed on the screen can be easily checked from any position within the car 15.

In other words, even when other users 7 are standing near the car operation panel 19, or when the car 15 is crowded with many users 7 and the line of sight to the display monitor 193 is blocked, The floor display 23 is designed so that the floor display characters on the screen can be easily confirmed visually.

Moreover, in this embodiment, the size of the floor display characters displayed on the floor display device 23 is made larger than when displaying various guidance information, advertising information, etc., thereby making it more useful for visually impaired people. gender is taken into account.

That is, the floor indicator 23 will be described in detail later, but for example, if the user 7 of the elevator 1 is a visually impaired person, especially a partially sighted user, in the car 15, , it is possible to enlarge and display the floor display characters.

Here, the size of the enlarged and displayed floor display characters is desirably larger than the size that can be seen by a user with a visual acuity of 0.01, which is the criterion for visual impairment grade 1, for example. In other words, even if a user 7 whose visual acuity is equivalent to 0.01 when converted to the line of sight distance of an adult of normal height stands against the wall inside the car 15 and visually recognizes the display on the floor display 23, The size of the display should be at least large enough to easily determine the content of the display.

For example, the size of the floor display characters enlarged and displayed on the floor display 23 is defined by the following formula (1) or formula (2).

Character size width (b)/line of sight distance (a)≧75/500… (1)
In this equation (1), when the line of sight position from the floor of the user 7 with visual acuity of 0.01 is 1500 mm, and the line of sight distance (a) from the line of sight position to the floor indicator 23 is 500 mm, - The horizontal character size width (b) is specified to be 75 mm or more.

Character size width (b)/line of sight distance (a)≧225/1500… (2)
In this formula (2), when the line-of-sight distance (a) from the line-of-sight position of a user 7 with visual acuity of 0.01 to the floor display 23 is 1500 mm, the vertical and horizontal font size width (b) is specified to be 225 mm or more.

Note that the manner in which the floor display characters are enlarged and displayed on the floor display device 23 includes, for example, the position, direction, angle, etc. of the floor display characters on the screen that can be displayed within the car 15 of the user 7 with low vision. It is also possible to control it depending on the standing position, or to make it blink or reverse.

Next, the elevator 1 according to the present embodiment will be briefly described.

As shown in FIG. 2, for example, the elevator 1 is installed in a building such as a commercial facility, and here an example is shown in which it is installed in an n-story building. That is, the elevator 1 of this embodiment is a general elevator device mainly used by the users 7 of this building.

In FIG. 2, in the elevator 1, a main rope 14 is stretched around a hoisting machine 13 disposed in a machine room 12 at the top of a hoistway 11, and a car 15 is attached to one end of the rope 14. At the other end, 16 counterweights are each suspended in a hanging style.

The car 15 is equipped with a car door 17 facing the hall doors 22 (22a, 22b,..., 22n) on each floor, and, for example, there is a door near the car door 17 for monitoring the boarding and alighting of the users 7. An in-car camera 18 is provided. As the in-car camera 18, it is also possible to use an in-car surveillance camera attached to the ceiling of the car 15.

In addition, inside the car 15, for example, as shown in FIG. 3, near the entrance where the car door 17 is provided, there is a car operation for the user 7 to perform a car call operation to set the destination floor. A board panel 19 is provided.

As shown in FIG. 2, in addition to the hoisting machine 13, the machine room 12 includes an elevator control device 30 connected to the car 15 via a tail cord (not shown).

On the other hand, each floor is provided with a hall door 22 (22a, 22b, . . . , 22n) for each landing 20 (20a, 20b, . . . , 20n). Near each hall door 22a, 22b,..., 22n, there are platform operation panels 21 (21a, 21b,..., 21n) for the user 7 to perform a platform call operation to set the destination direction, and notification lamps (not shown). (omitted) is provided. Although not shown, the hall operation panels 21a, 21b, ..., 21n transmit the operation of the hall call registration button or the hall call registration button by the user 7 to the elevator control device 30, and transmit the hall call registration button to the call registration section 201, which will be described later. It is equipped with a control panel wireless communication section for registering call information.

Note that communication with the elevator control device 30 by operating the hall call registration button may be performed by wire instead of the operation panel wireless communication section.

FIG. 3 is a block diagram showing an example of the configuration of the control system of the elevator 1 (elevator control device 30).

For example, as shown in FIG. 3, this elevator control device 30 includes a call registration section 201 as a registration section 200 for registering call information by a user 7, character data for displaying landing floor, and enlarged display. It includes a floor display character registration section 202 in which character data for etc. are registered in advance.

For example, the floor display character registration unit 202 registers each floor display character for each floor display character so that the position, angle, direction, etc. of the floor display character on the display screen changes when displaying the landing floor. Various character patterns may be stored in advance.

Alternatively, the floor display character registration unit 202 stores one basic standard size character pattern for each floor display character in advance, and software processing by the display control unit (control unit) 312 described later is performed. It is also possible to control the size, position, angle, direction, etc. of floor display characters on the screen to change.

Further, the elevator control device 30 includes, for example, a control section 130 that controls the car 15 of the elevator 1. The control unit 130 includes a visually impaired person determination unit (recognition unit) 310 that determines whether the user 7 is a visually impaired person, in particular, has amblyopia, a driving status management unit 311 that manages the driving status of the car 15, etc. , a display control section 312 that controls the display on the display monitor 193, the floor display 23, and the like.

For example, the visually impaired person determination unit 310 may recognize that the user 7 is in possession of a white cane WS based on the image taken by the in-car camera 18, or if the user 7 is recognized as having a destination floor on the car operation panel 19. When the human sensor 194S detects the touch of the user 7 to the Braille notation 194 attached to the button 191 or the like, it is determined that the user 7 is a visually impaired person who is likely to have amblyopia.

In addition, in this embodiment, it is determined whether or not the user 7 has amblyopia depending on whether or not the user 7 has a white cane WS and whether or not the user 7 has read the Braille in the Braille notation section 194. Although the system is designed to determine whether a person is visually impaired or not, the present invention is not limited to this, for example, a transmitter or communication device may be installed on the certificate (disability pass) carried by a visually impaired person with low vision, and the user with low vision can be detected by communication. may be specified.

Furthermore, the visually impaired person determination unit 310 can determine, for example, the standing position of the user 7 and the direction in which the user 7 is standing, based on the video captured by the in-car camera 18.

The operation status management unit 311 manages the opening/closing operations of the hall door 22 and the operation status of the car 15. For example, the operation status management unit 311 manages the operation status of the car 15, etc., and raises and lowers the car 15 based on the call information registered in the call registration unit 201. The hoisting machine 13 and the like are controlled to operate normally during normal times, and are controlled to operate during abnormal situations such as when an earthquake occurs.

The display control unit 312 causes the display monitor 193 and the floor display 23 to display, for example, the latest guide information and advertising information provided from the outside, and when landing on the floor, displays the arrival of the car 15. This controls the display of floors (floor display characters).

The display control unit 312 also controls, for example, the arrival floor to be displayed on the screen of the floor display 23 on the condition that the visually impaired person determination unit 310 confirms that the visually impaired user 7 is in the car 15. Control is performed so that the character size width of the landing floor display corresponding to the landing floor is expanded to a specified value of 75 mm or more.

Furthermore, this display control unit 312 will be described in detail later, but the display control unit 312 also uses information such as the position of the amblyopic user 7 in the car 15 confirmed by the visually impaired person determination unit 310 and the direction in which the user 7 is standing. Accordingly, it is also possible to change the position, direction, angle, etc. of the landing floor display on the screen of the floor display 23 (for example, see FIG. 4).

It is also possible to turn off the display of various guidance information, advertisement information, etc. on the floor display 23 during the ascending and descending operations other than when landing on the floor.

Here, the display of the landing floor on the floor display 23 by the display control unit 312 will be explained using an example in which the arrival floor is set as the "4th floor".

For example, the display control unit 312 sequentially reads out four types of character patterns with different orientations from among various character patterns corresponding to the landing floor (4th floor) stored in advance in the floor display character registration unit 202. Using four types of character patterns, the display on the floor display 23 is switched at regular intervals.

As a result, for example, as shown by the arrow in FIG. 4, the direction of the landing floor display enlarged on the floor display 23 can be changed to "normal position" with the display monitor 193 side facing forward, or "left sideways". It is possible to move (rotate) in four stages: , "reverse position", and "right sideways". As a result, regardless of where in the car 15 a user with amblyopia 7 is sitting, the user's line of sight will not be obstructed by other users 7 and the contents of the display can be more easily confirmed. .

FIG. 5 is a flowchart shown to explain the flow of processing related to displaying the landing floor on the floor display 23 of the elevator 1 described above.

First, when the weight sensor (not shown) confirms that the user 7 has boarded the car 15 (YES in step ST01), the elevator control device 30 detects the visually impaired person determining section 310 of the control section 130. For example, based on the image from the in-car camera 18, it is recognized whether the user 7 is a user with amblyopia based on the presence or absence of a white cane WS. Alternatively, based on the output of the human sensor 194S, for example, by touching the Braille notation section 194 (reading the Braille), it is recognized whether the user 7 is a user with amblyopia (step ST02).

If it is recognized that the user is not a user with amblyopia (NO in step ST02), various guidance information, advertising information, etc. are displayed on the display monitor 193 in the car 15 or the floor display 23 (step ST02). ST07).

On the other hand, if the user is recognized as having amblyopia (YES in step ST02), for example, the car 15 may land on a floor corresponding to the destination floor registered in the call registration unit 201 of the registration unit 200. is approaching (YES in step ST03).

Then, the display control section 312 reads out the character pattern corresponding to the landing floor stored in advance in the floor display character registration section 202 (step ST04), and displays it on the screen of the floor display 23. is switched to display the landing floor (step ST05).

At this time, it is also possible to move the position of the floor display characters enlarged and displayed on the screen of the floor display 23, change the direction, change the angle, reverse them, or make them blink. .

As a result, even if the user 7 is a visually impaired person with amblyopia, the user's line of sight will not be obstructed by other users 7 regardless of where they are in the car 15, and the display will be displayed. The arrival floor can be more easily confirmed.

In addition, there are users7 who are visually impaired (low vision) and who also suffer from hearing loss and have difficulty hearing the voice guidance for the arrival floor on the announcement device 192, and even those who are able-bodied, use smartphones, chat, etc. Displaying the arrival floor on a monitor on the ceiling is also useful for users7 who were so absorbed in the arrival floor that they missed the voice guidance for the arrival floor.

The above-mentioned display of the landing floor by the floor display 23 is repeated until the car door 17 is closed (NO in step ST06, ST05), and then it is switched again to various guidance information, advertising information, etc. (YES in step ST06, ST07).

As described above, according to the present embodiment, it is possible to improve the difficulty in seeing the floor display characters depending on the standing position of the user 7 in the car 15, and especially for the visually impaired user 7 who has low vision. This can greatly improve convenience for users7 who suffer from hearing loss or hearing loss.

That is, the floor indicator 23 is arranged on the inner ceiling of the car 15, and the floor indicator 23 has a size that can be easily read even by users 7 with weak eyesight to indicate the landing floor at the time of landing. The floor display characters are displayed preferentially.

As a result, even if a user with low vision 7 suffers from hearing loss and has difficulty hearing the audio guidance for the arrival floor on the announcement device 192, the user 7 will not have his/her line of sight blocked by other users 7 and will be able to see the information displayed. This makes it possible to reliably know the arrival floor.

Therefore, it is possible to eliminate the difficulty in seeing the landing floor display depending on the standing position in the car 15, and it is possible to visually recognize the floor display characters from any standing position, greatly improving convenience for the user 7. It can be improved.

Second form FIG. 6 is a schematic diagram illustrating the interior of the car 15 of the elevator 1 according to the second form. For example, the floor indicator 23a as a ceiling monitor can also be used as a ceiling light. This is an example in which a display device having an illuminance comparable to that of the ceiling light is used.

Here, parts that are the same as those in the first embodiment are given the same or similar symbols, and detailed explanations are omitted.

According to this second form, the convenience for the user 7 can be improved as in the case of the first form described above, and furthermore, by integrating with the ceiling lighting, the interior design of the car 15 can be simplified. becomes possible.

As shown in FIG. 6, for example, the car 15 displays various guidance information, advertising information, etc. in addition to the ceiling monitor, and also enlarges the landing floor display using landing display characters. A floor display device (monitor device) 23b can also be provided as a wall monitor.

It is desirable that the floor display device 23b as a wall monitor be provided at a height of 1900 mm or more from the floor surface of the car 15, for example, on other wall surfaces other than the front wall surface.

According to such a configuration, as the number of monitors for displaying the landing floor increases, it becomes easier and more reliable for the user 7 to visually check the floor display characters without changing his position. This will further improve convenience.

In addition, in each of the embodiments described above, it is also possible to configure the size of the enlarged floor display characters to be automatically adjusted depending on the standing position of the user 7, etc. It is also easily possible to control the position, size, and direction of the landing display characters while moving them on the screen.

Further, on the floor display devices 23, 23a, 23b, various guide information, advertising information, etc. may be displayed in an enlarged manner so that the user 7 with low vision can easily read them.

Furthermore, in an emergency, evacuation information, disaster information, etc. may be displayed in an enlarged manner.

Furthermore, the invention is not limited to the elevator 1 installed inside a building, but can also be applied to, for example, an elevator system installed outside a building.

Although the embodiments of the present invention have been described above, the embodiments are presented as examples and are not intended to limit the scope of the invention. Moreover, this novel embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.
