Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation control device suitable for use by visually impaired persons.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. Hei 7-206290 discloses that a dedicated landing hall button for visually impaired persons is provided, and a broadcasting facility is provided in conjunction with this button to notify an elevator user of a car call registration state by voice. ing.

[0003] Japanese Patent Application Laid-Open No. Hei 9-110319 discloses an automatic driving system in which a hall and a car include a call registration device, and the call registration device is equipped with a braille plate expressed in Braille so that a visually impaired person can operate the call registration device. In the elevator, a sensor for detecting the contact of the human body with the Braille plate is attached, and the Braille contents of the Braille nameplate touched are broadcasted by voice using a voice guidance device based on the detection signal, and the visual impairment of the elevator. A voice guidance device is described.

[0004] Japanese Patent Application Laid-Open No. 8-34581 discloses that
Braille nameplate to detect the touch of the elevator user,
And a door opening time extending means for sending a signal for extending the door opening time to the electric opening / closing device of the door when detecting that the button switch is pressed within a predetermined time after detecting that the Braille nameplate is touched. A control device for an elevator is described.

[0005]

The prior art has the following problems.・ It is difficult for visually impaired people to understand the opening and closing of the door and the current floor. Some voice guidance devices are installed, but they do not always provide sufficient content.On the contrary, if an office is near the elevator installation section, voice guidance will be used instead of those who work in the office. May cause audio noise. -If there is visual impairment, it may take time to get on and off the elevator and operate it. If the opening and closing time of the door is short, it is difficult to get on and off according to the opening and closing timing of the door.・ If there are multiple elevators in the elevator hall,
Even if there is a voice guidance device, it is sometimes difficult to know which elevator came due to the echo in the hall.・ Although there is an invention that automatically recognizes a person who touches a Braille label as a visually impaired person, the proportion of those who can read Braille is low, and a considerable number of visually impaired people do not even touch the Braille label. it is conceivable that.

In view of the above, the present invention determines whether or not a user is visually impaired in accordance with an elevator call or a search for a destination floor button when the visually impaired uses an elevator. Elevator operation control that reliably recognizes the visually impaired, does not reduce the driving efficiency during normal operation in the visually impaired driving mode, and reduces voice noise to surrounding people It is intended to provide a device.

[0007]

SUMMARY OF THE INVENTION A tactile sensor is provided on an operation panel for calling an elevator in an elevator hall, operation buttons on an operation panel in an elevator, and a face plate, and logically senses the act of a visually impaired person searching for a button. Automatically recognizes visually impaired people. As a result, it is possible to provide the visually impaired person with elevator operation (usability) suitable for the elevator situation and the visually impaired person. Here, the elevator call button (up) and the elevator call button (down) are collectively called a landing button, and the landing button and the destination floor button are collectively called operation buttons.

[0008] The visually impaired person searches while checking the face plate portion and the number and position of the buttons in order to operate the target operation button. By paying attention to this series of actions and the touched portion, it is determined whether or not the person is visually impaired based on the relationship between the touched portion, the pressed button, and the timing.

[0009] If the above-mentioned person is determined to be visually impaired, it is possible to extend the door opening time or add optimal audio information to the visually impaired person, thereby improving the usability of the elevator for the visually impaired person.

[0010] By automatically recognizing, by operating the above function as a visually impaired mode only when the visually impaired is used, the driving efficiency during normal driving can be prevented from being reduced, and voices to surrounding people can be heard. Noise can be reduced to a minimum.

According to the above-mentioned method, a visually impaired person who does not read Braille, that is, does not rely on a Braille nameplate, can be distinguished as a visually impaired person, and the usability of more visually impaired people can be improved. .

[0012] Since a button or the like dedicated to a visually impaired person is not provided, there is an advantage that a tactile information is not confused and a healthy person cannot be specially viewed by a disabled person.

[0033]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of an elevator system having a visually impaired person automatic recognition and a visually impaired person driving mode.

A door 8, a destination floor display panel 9, and an operation panel 10 are provided in a car 13 of the elevator 1. On the operation panel 10, a voice guidance device for a visually impaired person (voice guidance for a visually impaired person) is provided. A device 12), a destination floor button 11 and the like are provided. An elevator control device 2 used for controlling the operation of the elevator is provided. The elevator control device 2 has an operation controller 4 that is provided with input values from the operation panel 5 on the hall side, inputs the current position of the elevator car 13 or the reservation status, and controls the operation. The operation controller 4 and the microcomputer 3 may be integrally expressed. The operation panel 5 on the hall side includes a face plate section 6 and an elevator call button (up) and an elevator call button (down) 7 which are landing buttons. The face plate section 6 is connected to a detecting device 14 so that when a person touches it, it can be electrically detected, and a detection signal can be input to the microcomputer 3. Tentacle detection may be performed for the elevator call button (up) and the elevator call button (down) 7. Here, tentacle detection for the face plate portion, the elevator call button (up), and the elevator call button (down) is collectively referred to as tentacle detection for the face plate.

In general, a visually impaired person places one hand with a part (mainly an end face) of the face plate 6 as a reference point while using both hands, and searches for tactile information with the other dominant arm. To go. Since there are up and down landing buttons 7 on the middle floor, the visually impaired person selects one of the two buttons after checking the positional relationship between the two buttons.

That is, when the user searches the face plate portion 6 while touching the fingertip, touches the upper and lower buttons, and presses either of them within a certain period of time after the touch, it is regarded as a visually impaired person. Can be. In the case of a sighted person, the operation of touching both buttons is not usually performed because the upper and lower buttons can be checked. It is possible to determine the visually impaired person information and the sighted person information from the information extracted by the difference in the operation.

An example of a pattern of recognition by the button tentacles of a visually impaired person will be described by taking an example in which a button on an intermediate floor or an upward landing is pressed. FIG. 2 shows an example of a button recognition pattern for a visually impaired person.

(1) Using both hands, search for the face plate portion 6 where the landing button 7 is considered to be. The end face 21 understands and recognizes a suitable shape.

(2) One hand 22 is stopped on the face plate 6 (continuation of the tentacle detection state), and the landing button 7 is searched for with the other hand 23. Confirm the upper landing button sequentially with one hand (shown in black on the drawing; the same applies hereinafter).
And then check the landing button on the bottom. The continuation of the tentacle detection state can be used as an important signal in recognition of the visually impaired.

(3) The other hand 23 is moved up and down from the position of the found landing button 7 to search for another button. Make sure there is another button below. And make sure there is another button on top. In this state, the hand 22 is touching the face plate 6.

(4) Since two buttons are confirmed up and down, it is determined that the upper button is upward and is pressed. That is, it is possible to recognize that a visually impaired person is a user on condition that pressing of the elevator call button (up) or the elevator call button (down) is detected. Elevator call button (up) on the operation panel on the hall side
It may be recognized that the use is made by a visually impaired person based on the fact that both the elevator call button (down) and the elevator call button (down) are sequentially touched under the detection of the touch state of the face plate unit 6.

The detection of two tentacles on the face plate on which the landing button or the destination floor button (operation button) is disposed is a condition for recognizing a visually impaired person.

The landing button on the middle floor is a stroke sensor button with a touch sensor, and the information on the touch of the button, the relationship between the pressed information and the time are calculated, and as a result, it is determined whether or not the person is visually impaired. .

As a logic, first, the judgment is started from the moment when one of the buttons is touched (including the case where the button is directly pressed). Then, if any of the upper and lower buttons is pressed after the upper and lower two buttons are touched, it is determined that the visually impaired person is from the button search behavior of the visually impaired person. When only one of the buttons is touched and that button is pressed, the person is determined to be a sighted person. As described above, the recognition means of the tentacle detection includes: a face plate portion, a specific setting portion on the face plate portion, a touched place such as a button surface portion, an order of touched places, a touched time, a tentacle to a landing button, The determination of a visually impaired person is logically made based on the time from the start of the tentacle detection or the end of the tentacle detection to the pressing of the landing button. If it is determined that the person is visually impaired, the mode is shifted to the visually impaired mode. The operation and release of the elevator in the visually impaired person mode will be described later.

Also, while the visually impaired person searches for a button, he may change his mind and stop touching the face plate 6 in order to stop using the elevator. Set time limit for stopping and resetting the judgment when no touch or stroke is pressed after a certain time
Tlimit shall be provided. In other words, Tlimit is a constant that determines whether or not the visually impaired person resets the judgment before the next time a sighted person or the like enters the button operation after stopping the operation without pressing the button, so a relatively short time of several seconds is searched. You only need to set the mode. In the present embodiment, Tlimit
To 3 seconds.

It should be noted that as a premise, unless one person performs an erroneous operation, normally only one stroke button should be pressed, so that the logical judgment is reset every time the stroke button is pressed.

FIG. 3 shows a button circuit sensor diagram. The landing button 7 of the operation panel 5 is configured as a touch sensor + stroke sensor button.

In the figure, A, C: touch sensor circuit output A general touch sensor button circuit capable of recognizing whether or not a button surface is touched by an induced current method or the like. Turn ON when touching. B, D: Stroke sensor circuit output A general stroke button circuit that turns on the contacts when the button is pressed for several millimeters. Turn ON when the contacts are connected. E: OR output of A and C F: OR output of B and D

Here, E and F (OR circuit) are described in order to explain the following logic flow, but in actuality, the circuit output lines of A, B, C, and D indicate the logic. This is an input of a microcomputer (including a timer or the like) to be determined, and the calculation may be performed in the microcomputer, and there is no need to provide such an OR circuit outside the microcomputer.

When the landing button is directly pressed,
First, the logic is such that the output of the touch sensor circuit is turned on and then the output of the stroke sensor circuit is turned on.

FIG. 4 shows one flow of the visually impaired person recognition circuit. In the figure, T is a timer, and Tlimit is a setting for stopping and resetting when a person touches a button and then does not touch or does not press a stroke even if a certain time has elapsed after leaving the button. R indicates a time limit, and R is a flag indicating whether or not both buttons have been touched. When both buttons are touched, R = 1, otherwise R = 0.

Also, in the figure, S4 to S11 show cases where the upper button was touched first, and S15 to S21 show cases where the lower button was touched first. The T count indicates that the time of T is counted.

In the figure, when T> Tlimit (S1
At END (S25) at (1, S21), when R = 1 (S22, S23), the visually impaired person is recognized as a user, and the elevator is operated in the visually impaired driving mode S24.

FIG. 5 shows the operation of setting and canceling the mode after the recognition of the visually impaired person. As shown in the figure, as an example, a visually impaired person A gets on the second floor and registers the fifth floor, and a sighted person B who gets on the same floor registers the sixth floor, and a sighted person C gets on the third floor and goes on the seventh floor. Indicates the case of registration. The second to sixth floors are in the visually impaired driving mode. The driving state in the viewer driving mode is shown on the right side of the figure.

If it is recognized that the person is visually impaired, the elevator operated by the call button is set to the visually impaired mode. The timing is set to the visually impaired mode from the point in time when the landing button for discriminating the visually impaired is pressed, the elevator in the called direction arrives, and the destination pressed by the operation panel in the elevator on that floor It is assumed that the vehicle arrives at the top floor (upward) or the lowest floor (downward) of the floor button, and the elevator door opens and closes. Exit blind mode when closed. This means that even if a person is recognized as a visually impaired person, if another person gets on the same floor and there are multiple destination floors pressed in the elevator, it is necessary to specify which destination floor button the visually impaired has pressed. Is difficult.

The identification is possible if a certain kind of visually impaired person recognizing function is also provided on the operation panel in the elevator.

Next, an example of the operation in the visually impaired driving mode will be described.

When the elevator is recognized as a visually impaired person, physical mechanical control such as provision of voice guidance information and control of door opening / closing time in consideration of the visually impaired person is considered effective. Information for the visually impaired includes elevator operating conditions, explanations of operations and functions, floor guidance, getting on and off people, opening and closing doors, ease of use of the operation panel, information on the current floor during ascent and descent, and emergency response information. And so on.

1) Extension of Door Opening Time The elevator door opening time is extended as compared with normal times so that visually impaired persons can get on and off slowly. (Example) Normally 5 seconds → 15 seconds in visually impaired person mode

2) Standby function for a fixed time Normally, if the destination floor is not registered even if the elevator is called and the passenger gets in, when the elevator is called on another floor, the elevator starts to move there. A visually impaired person is expected to take a long time to register the destination floor, and the elevator may operate in such an unexpected direction. Therefore, in order to secure time until a visually impaired person gets in and registers the destination floor of the operation panel in the elevator, the elevator is put on standby in that floor (waiting for destination floor input) for a certain period of time. Waiting is released after a certain period of time or when the destination floor is registered. (Example) Set the fixed time to about 10 seconds

3) Information on additional guidance for hall voice ○ Time from when the hall button is pressed until the elevator comes to the hall Equipment configuration: hall voice guidance device ・ Information on the location of the target elevator for the hall button (decimal number) Reason: When controlling multiple elevators with one landing button, visually impaired people do not know which is located and which elevator is heading to the target floor. Example “Please wait for the elevator on the left side” ・ Elevator driving floor information Reason: If there are multiple elevators, the driving floor may be restricted. Further, if the operating floor is known, it is easy to imagine the layout of the destination floor buttons on the operation panel in the elevator. Example "This elevator operates from the XX floor to the XX floor." ・ Position information of the operation panel in the elevator Reason: The position of the operation panel in the elevator differs depending on the model. This makes it easier for visually impaired persons to find the operation panel. Example “The operation panel in the elevator is on the left sleeve wall after entering.” ・ Current operating condition of the elevator Reason: Waiting for the elevator is anxious for the visually impaired. Informing the user of the current position as appropriate increases the sense of security. In the case of a store or the like, it is also possible to know what floor is on what floor by adding floor guidance. Example "Elevator is currently suspended at the 3rd floor women's clothing section.
・ It will be coming soon. ・ Opening / closing of doors, opening time extension information and getting on / off warning information Reason: By notifying that the opening time of the door will be extended, it is possible to relax here mentally. Example "The door will open for about 15 seconds. Please get in slowly.""The door will open. Please be careful.""The door has opened. Please be careful of steps and gaps." Information Reason: The visually impaired does not know whether or not anyone will get off before boarding. By notifying in advance that there is a person getting off the elevator at that floor (it can be recognized from the fact that the destination floor has been reserved on the operation panel in the middle), it is possible to avoid troubles such as inadvertently colliding with the person getting off. Example "Some people get off this floor. Please be careful."

4) Elevator Voice Added Guidance Information When a visually impaired person recognizes an elevator user,
The floor floor of the hall using the visually impaired is detected from the destination floor button 11, and the hall guidance information is broadcast by voice for the floor.・ Information in elevator Equipment configuration: Voice guidance device in elevator ・ Current floor, floor facility guidance information Reason: The display of the indicator cannot be recognized by the visually impaired,
It can be difficult to tell what is on the current floor or which floor. In addition, it is safe to know roughly where stairs and toilets are effective in an emergency. Example: "Women's clothing section on the 3rd floor. The stairs are on the right and the restroom is on the left." ・ Emergency response information Reason: It is difficult for visually impaired people to understand what to do if the elevator stops due to a malfunction. There is. Example: "In an emergency, keep pressing the button at the top of the operation panel. Use the intercom ..." ・ Information about opening and closing the door and getting on and off the door Reason: By giving information on the opening and closing of the door, it is possible to get on and off comfortably mentally. By notifying the information of the gap and the step between the elevator and the hall, safe getting on and off can be encouraged. Example "The door will open. Please be careful.""The door has opened. Please be careful of steps and gaps."

5) Blinking function of the destination floor button on the operation panel in the elevator ・ The destination floor button pressed on the floor where the visually impaired person has been discriminated is pressed before arrival at that floor (for example, when the user arrives two seconds before arriving at the floor). Blink until just before the door opens). Reason: There is a possibility that even a visually impaired person can be identified as a visually impaired person. In the case of a person with low vision, if the indicator is not visible in an elevator without voice guidance, it may be determined whether or not the user has arrived at the target floor by turning on and off the destination floor button pressed. By flashing the destination floor when arriving, we think that it is possible to make it easier for people with low vision to know that the floor they pressed has arrived.

6) Voice guidance alert chime-Immediately before the important guidance that relies on voice for the visually impaired, such as the arrival floor, opening and closing of doors, etc., is voiced by voice guidance in the elevator, it is warned that voice guidance will be played. Ring the chime. The arrival forecast chime changes the tone.
As a result, oversight can be prevented. Example: Arrival floor "Chin""3rdfloor" Close the door "Boo""The door closes"

7) Door opening / closing chime-Even when there is voice guidance for opening / closing the door, it is sometimes difficult to understand the timing of closing and the state of opening. Therefore, a suitable chime is sounded during the opening / closing operation. For example, a pleasant sound when opened. A little unpleasant sound like a buzzer when closing.

FIG. 6 shows an operation flow for recognizing a visually impaired person.

An operation flow when a visually impaired person is recognized will be specifically described based on some operation examples. To make it easier to see the difference between visually impaired mode and normal mode,
Describe in contrast. In addition, an example of the function of the user's behavior and the operation of the elevator side is shown for the extension of the door opening time, the provision of additional voice guidance information, and the voice guidance alert chime. The detailed contents are as shown in the figure.

FIG. 7 is a block diagram showing the configuration of an elevator system provided with a visually impaired driving mode.

The landing system 41 includes a button switch 42, a microcomputer 43, and a sound output device 4 for each floor.
4 is provided. Each elevator 45 includes an audio output device 46,
A door opening / closing control device 48 for the door opening / closing control 47 and a microcomputer 49 are provided. The elevator 45 is controlled by an elevator operation control device 50 that inputs, processes, and outputs an input value from the landing-side system 41 and an elevator current value.

The sound device also includes, in addition to the sound, a sound effect output such as an alert sound. With this configuration, all the operation examples in the visually impaired person mode can be realized.

In the uppermost floor and the lowermost floor where the elevator operates, unlike the middle floor, since there is only one landing button, the visually recognizable person cannot be identified by the conventional recognition method. Therefore, for these floors, refer to the recognition system as in the third embodiment.

FIGS. 8 and 9 show a second embodiment of the method for automatically recognizing a visually impaired person.

FIG. 8 is a diagram showing a button circuit sensor. In this example, the touch sensor 5 is provided on the face plate 6.
1 is provided. The function of the face plate unit 6 in the above embodiment is searched by the touch sensor 51. That is, the touch sensor 51 forms a part of the face plate unit 6. In this case, an AND operation between the face plate unit 6 and the touch sensor 51 may be performed. As the touch sensor, those commonly used, such as an induction current type, an infrared detection type, and a micro switch type, are used. Therefore, tentacle detection can be either directly touched or
This includes both cases where the hands are indirectly touched.

The visually impaired person touches the face plate 6 and then touches the touch sensor 51 provided between the two stroke buttons 52.

In the figure, A, B: stroke sensor circuit output A general stroke button circuit in which a contact is turned on when a button is pressed by several millimeters. Turn ON when the contacts are connected. C: Touch-sen circuit output A general touch state that can recognize whether or not the button surface is touched by an induced current method is set to ON. D: Stroke or output of A and B Paying attention to the above-mentioned behavioral principle and application of button search for the visually impaired and (4) of an example of the cognitive pattern of the button for the visually impaired, in this cognitive pattern, the upper and lower buttons must be used. You will touch between. Therefore, a touch sensor 51 is provided between these two buttons on the face plate portion, and it is determined whether or not the person is visually impaired based on the information touched on this portion and the information on pressing the button (and the relationship of time). ing.

Here, D (blue circuit) is described in order to explain the following logic flow.
Each of the circuit output lines B and C is an input of a microcomputer (including a timer or the like) for determining the logic, and the calculation may be performed in the microcomputer. Such an OR circuit is provided outside the microcomputer. No need to be.

FIG. 9 shows the flow of the visually impaired person recognition circuit. The flow includes steps from S31 to S39.

In the figure, T indicates a timer, and Tlimit indicates that when a person has touched the touch sensor and has not touched the touch sensor for a certain period of time, or has not pressed a stroke, the judgment is stopped and reset. Set time limit for. Since the touch sensor portion is limited, it is possible that the user touches a face plate portion or a button other than this portion. Here, Tl
Set imit = 20 seconds.

In this method, the circuit is implemented by a simpler circuit than in the first embodiment. On the other hand, the probability that a sighted person can casually touch the touch sensor unit is higher than that in the first embodiment. May be lower.

FIGS. 10 and 11 show a third embodiment.
FIG. 10 shows a button circuit sensor.

In the figure, a touch sensor 61 is provided on the entire upper surface of the face plate portion 6. That is, the face plate portion is the touch sensor 61. Other configurations and flows are the same as those of the second embodiment. 62 is a stroke button.

The lowest floor landing button is configured as shown in FIG. 11, and is provided with a touch sensor 61 and a stroke button 62 as in FIG.

In the method of the third embodiment, a portion that is difficult for a sighted person to touch is not used as a touch sensor portion, and a portion that is easy for a visually impaired person to touch is specified as follows.
Various variations are possible. By adopting such a variation, it is possible to combine with the above-described recognition method, and it is possible to increase the recognition rate with a visually impaired person.

FIG. 12 is a diagram showing a button circuit sensor according to the fourth embodiment.

When the visually impaired searches for the face plate 6 and then searches for the landing button 7 on the face plate, the hand (71) of the face plate is fixed as a reference for searching for the button. Pay attention to the action of touching, and let this part be the touch sensor unit 72. Then, if the total touched time from the touching of this portion to the pressing of the stroke button is equal to or longer than a predetermined time, it is determined that the person is visually impaired. The logic flow diagram is the same as in the third embodiment. In this case, the buttons on the top floor and the bottom floor are also effective.

FIG. 13 is a button circuit sensor diagram according to the fifth embodiment.

When a visually impaired person locates the face plate portion 6 and then locates the landing button 7 on the face plate portion, it locates the button position by sliding the finger. Focusing on the action that ends, the peripheral part 74 of the button is used as the touch sensor 74. (A) shows an example of a square button, and (B) shows an example of a round button. Then, when the stroke button is pressed after touching this portion, it is determined that the person is visually impaired. By narrowing the range, even if the sighted person naturally touches the face plate portion 6, the probability that the sighted person will not be distinguished as a visually impaired person can be increased. The logic flow diagram is the same as in the second embodiment. This example is also effective for the buttons on the top floor and the bottom floor.

FIG. 14 is a diagram showing a button circuit sensor according to the sixth embodiment.

Although it is considered that the Braille label is a touch sensor, it is often difficult for a sighted person to touch the Braille label with his or her interest, and it is difficult to distinguish the Braille label as it is.

Therefore, focusing on the action of a visually handicapped person searching for braille while touching, a touch sensor unit 76 is provided between the upper and lower braille nameplates 75 or in the vicinity thereof. Then, when the stroke button is pressed after touching this portion, it is determined that the person is visually impaired. This is because a sighted person would touch only the Braille nameplate, and would not touch this touch sensor, even if he or she was interested.

It is also considered possible to increase the probability of discrimination by providing a touch sensor unit that can be independently detected on the Braille name plate unit and calculating the information touched on each.
The logic flow diagram is the same as in the second embodiment.

FIGS. 15 and 16 show the automatic recognition and operation of the visually impaired person in the elevator. FIG. 15 is a diagram of a destination floor button circuit sensor.

In the figure, a destination floor button 11 is provided on the face plate portion 81 of the operation panel 10.
The destination floor button 11 functions as a touch sensor + stroke sensor button. The recognition pattern is the same as in FIG. Until now, the automatic recognition and operation of the visually impaired person in the elevator hall, but after getting in the elevator, focusing on the search action of the visually impaired person specifying the destination floor, etc. Identification of the visually impaired when pressed, the interior of the elevator may be dark, so if people with low vision perform the same search,
The range that can be identified as a visually impaired person can be expanded, and more visually impaired persons can be provided with a means for improving the usability of the elevator.

The principle of automatic recognition can be determined by applying the embodiment in the case of the landing button. For example, as in the first embodiment, a touch sensor + stroke sensor button is used as a destination floor button on an operation panel in an elevator. The visually impaired (people who do not read Braille)
While imagining the number of buttons on the operation panel and the arrangement based on general customs, for example, the user sequentially searches 1, 2, 3,... For this reason, the user often touches a plurality of adjacent destination floor buttons.

Therefore, based on the relationship between the information touched on the destination floor button and the information subsequently pressed by the stroke and the time, the user touched a plurality of adjacent (continuous) destination floor buttons within a certain time, and then When the button is pressed, it can be determined that the destination floor button is the destination floor of the visually impaired person.

FIG. 16 shows the flow of the visually impaired person recognition circuit. The flow includes steps from S41 to S52.

In the figure, J is a primary matrix storing SN (different from the immediately preceding one). Let S be the (ON) output information touched as a touch sensor. (SN is the floor of the destination floor button touched) Let P be the output information of the destination floor button pressed with a stroke. (PN is the floor of the pressed destination floor button) T is a timer. Tl
imit is the set time limit for stopping and resetting the judgment when a person touches the button and does not touch the button for a certain period of time after release, or when the stroke is not pressed.

Here, Tlimit is set to about 3 seconds.

In the comparison between P and J, that is, the comparison with the set condition (S50), when the second-to-last SN of the stored primary matrix J is (PN + 1) or (PN-1) (that is, when pressing). If the user touches an upper or lower floor button immediately before the pressed button), the determination is YES. Otherwise, it is NO. That is, it is recognized as a visually impaired person.

(Example) P _N = 6, J = (6) → sighted person P _N = 6, J = (12,6) → sighted person (possibility of touching a button on the twelfth floor in an attempt to press the sixth floor) _{there) P N = 6, J =} (2,1,2,3,4,5, 6) → the visually impaired (touching on the fifth floor of the button before pressing the 6th floor)

As described above, when the operation panel in the elevator is automatically recognized as a visually impaired person, the operation mode is set to the visually impaired person from that point, and the operation example in the visually impaired person mode when recognized by the landing button The operation shown in FIG.

However, it is assumed that the destination floor of the visually impaired person can be specified, and the visually impaired person mode is canceled after arriving at the destination floor set above and opening and closing the door.

When a voice guidance device is provided, the following functions can be added. That is, at the destination floor button of the operation panel in the elevator,
When a plurality of (for example, three or more) destination floor buttons are touched within a certain period of time without a stroke being pressed, it is recognized that the touching person is a visually impaired person (the probability is high). From that point, if you output the number of the floor of the button you are touching, you can know which destination floor button you are touching, so that you can find the target button accurately and quickly Will be.

Of course, if the destination floor is pressed after the search,
(Example) If voice guidance such as "Registered the 6th floor" appears, there is no doubt that it will be more convenient.

Other than the above, the method of recognizing the visually impaired person on the operation panel in the elevator is the same as the operation panel at the landing. The destination floor button is a touch sensor & stroke button, and a plurality (for example, three) When the button is pressed after touching the above buttons ・ The entire faceplate of the elevator operation panel is used as a touch sensor, and the button is pressed after touching for a certain period of time ・ The faceplate between the Braille nameplates Is a touch sensor, and a button is pressed after touching it. ・ A braille label is used as a touch sensor, and a button corresponding to the braille is pressed after touching the braille, etc. It is possible to recognize.

According to the present invention, a tentacle state of a face plate which is visually touched by a visually impaired person and touched by one hand and continuously touched by one hand is detected, and this is set as one condition. The tentacle state of the
When the D signal is present, the visually impaired person is recognized as a user, and furthermore, the time until the operation button is pressed is determined to be logically visually impaired. Since the recognition of the visually impaired person can be performed, the visually impaired person is determined to be the user according to the operation button search action of the visually impaired person. Will be Along with this, the elevator operation can be shifted to the visually impaired driving mode under a high recognition rate, so services such as extension of door open time, provision of additional voice guidance information, voice guidance warning chime etc. are ensured. Will be able to do it. Also,
