Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator operation control apparatus suitable for use by visually impaired persons.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 7-206290 describes that a dedicated hall button for visually handicapped persons is provided, and a broadcasting facility is provided for notifying elevator users of the car call registration status by linking these buttons.
[0003]
Japanese Patent Application Laid-Open No. 9-110319 includes a call registration device in a hall and a car, and in an elevator of an automatic driving system equipped with a Braille plate expressed in Braille so that a visually impaired person can operate the call registration device, A sensor for detecting that a human body has come into contact with the Braille board, and the Braille content of the touched Braille nameplate is broadcasted by voice by a voice guidance device according to the sensing signal. An apparatus is described.
[0004]
Japanese Patent Application Laid-Open No. 8-34581 discloses a braille nameplate that detects that an elevator user has touched, and a button switch that is pressed within a predetermined time after detecting that the braille nameplate is touched. When this is detected, there is described a control device for an elevator, comprising door opening time extension means for sending a door opening time extension signal to the door electric opening and closing device.
[0005]
[Problems to be solved by the invention]
The prior art includes the following problems.
・ It is difficult for visually impaired people to understand the opening and closing of doors and the current floor. Some voice guidance devices are installed, but they do not always provide sufficient content. Conversely, if the office is close to the elevator installation, the voice guidance is changed and the person who works in the office. May cause audio noise.
・ If there is a visual impairment, it may take time to get on and off the elevator and operate, and if the door opening and closing time is short, it is difficult to get on and off in accordance with the door opening and closing timing.
・ If there are multiple elevators in the elevator hall, it may be difficult to know which elevator has arrived due to echoing the hall even if there is a voice guidance device.
・ There is an invention that automatically recognizes people who touch the braille nameplate as visually impaired people, but the percentage of visually impaired people who can read braille is low, and there are quite a few visually impaired people who do not even touch the braille nameplate. it is conceivable that.
[0006]
In view of such a point, the present invention reliably determines whether the user is visually impaired or not according to the behavior of elevator call or destination floor button search when the visually impaired uses the elevator. Provided an elevator operation control device that recognizes people with disabilities and does not reduce the driving efficiency during normal driving by the visually impaired driving mode, and can reduce voice noise to people around. The purpose is to do.
[0007]
[Means for Solving the Problems]
Tactile sensors are provided on the operation panel that calls the elevator in the elevator hall, the operation buttons on the operation panel in the elevator, and the face plate, and the visually impaired person automatically recognizes the visually impaired person by sensing the action of searching for the button. . Thereby, the operation | movement (usability) of the elevator suitable for the condition of an elevator and a visually handicapped person can be provided to a visually handicapped person. Here, the elevator call button (up) and the elevator call button (down) are collectively referred to as a landing button, and the landing button and the destination floor button are collectively referred to as an operation button.
[0008]
・ The visually handicapped person searches for the desired operation button while confirming the number and position of the face plate and buttons. Paying attention to this series of actions and the touched part, it is determined whether or not the person is visually impaired from the relationship between the touched part, the pressed button, and the timing.
[0009]
When it is determined that the person is visually impaired as described above, it is possible to extend the door opening time or add audio information that is optimal for the visually impaired person, thereby improving the usability of the visually impaired person.
[0010]
・ By automatic recognition, only when using visually impaired people, it is possible to operate the above functions as a visually impaired person mode so that the driving efficiency during normal driving is not reduced. It can be reduced to the minimum.
[0011]
-With the above method, visually impaired persons who do not read Braille, that is, do not rely on Braille nameplates, can be distinguished from visually impaired persons, and the usability of more visually impaired persons can be improved.
[0012]
・ Because there is no special button for visually handicapped people, there is the merit that it does not lead to a special view of a healthy person for a handicapped person without confusion as tactile information.
[0013]
・ Because it can be constructed with the application of conventional technology and a simple system, cost increases can be suppressed.
[0014]
For example, a landing button on the middle floor is a stroke button with a touch sensor, and the relationship between touched information and time is calculated to determine whether or not the person is visually impaired. When it is determined that the person is visually impaired, the control of the elevator is changed to extend the door opening / closing time or add audio information optimal for the visually impaired. In addition, the face plate can be used as a touch sensor, and the touched part can be identified to identify the visually impaired person.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0034]
FIG. 1 shows an example of an elevator system having a visually impaired person automatic recognition and a visually impaired driving mode.
[0035]
A door 8, a destination floor display board 9, and an operation panel 10 are provided in the car 13 of the elevator 1, and a voice guidance device (voice guidance device 12 for the visually impaired) is provided on the operation panel 10 for the visually impaired. A destination floor button 11 is 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 provides an input value from the operation panel 5 on the hall side and inputs the current position or reservation status of the elevator car 13 to control the operation. The operation controller 4 and the microcomputer 3 may be expressed integrally. The hall-side operation panel 5 includes a face plate portion 6 and an elevator call button (up) and an elevator call button (down) 7 which are landing buttons. The face plate unit 6 is connected to the detection device 14 so that it can be electrically detected when a person touches it, and a detection signal can be input to the microcomputer 3. It is good also as a tentacle detection with respect to 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.
[0036]
A visually handicapped person generally uses one hand to place one hand with a part of the face plate part 6 (mainly the end face part) as a reference point and looks for tactile information with the other hand. Since there are up and down landing buttons 7 on the middle floor, the visually impaired person selects one after confirming the positional relationship between the two buttons.
[0037]
That is, it can be regarded as a visually handicapped person when searching while touching the fingertip on the face plate portion 6, touching the two upper and lower buttons, and pressing either button within a certain time after touching. In the case of a sighted person, since it can be confirmed by looking at the upper and lower buttons, the operation of touching both buttons is not normally performed. It is possible to discriminate between visually impaired information and sighted person information from information extracted based on the difference in operation.
[0038]
An example of a recognition pattern using a button tentacle of a visually handicapped person will be described by taking as an example a case where an upstairs landing button is pressed. FIG. 2 shows an example of a button recognition pattern of a visually impaired person.
[0039]
(1) Using both hands, search for the face plate portion 6 that seems to have the landing button 7. The end face 21 understands and recognizes such a shape.
[0040]
(2) One hand 22 is rested on the face plate portion 6 (continuation of the tentacle detection state), and the landing button 7 is searched with the other hand 23. Use one hand to check the upper landing button (shown in black on the drawing, the same applies hereinafter), and then check the lower landing button. The continuation of the tentacle detection state can be used as an important signal in the recognition of the visually impaired.
[0041]
(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. Make sure there is another button on top. In this state, the hand 22 touches the face plate portion 6.
[0042]
(4) Since the upper and lower buttons are confirmed, it is determined that the upper button is going up, and it is pushed. That is, it is possible to recognize that the visually handicapped person is a user on condition that a press on the elevator call button (up) or the elevator call button (down) is detected. The use of the visually impaired person based on the fact that both the elevator call button (up) and the elevator call button (down) on the operation panel on the hall side are sequentially touched under detection of the touch state of the face plate unit 6. May be recognized.
[0043]
The detection of two tentacles on the face plate portion where the landing button or the destination floor button (operation button) is arranged is a condition for recognizing whether the person is visually impaired.
[0044]
The platform button on the middle floor is a stroke sensor button with a touch sensor, and the information on touching the button, the relationship between the pressed information and the time are calculated, and as a result, it is determined whether the person is visually impaired.
[0045]
As a logic, first, the determination is started from the moment when one of the buttons is touched (including when it is directly pressed). Then, if any one of the upper and lower buttons is pressed after the two upper and lower buttons are touched, it is determined that the visually impaired person is a visually impaired person based on the button search behavior of the visually impaired person. When only one of the buttons is touched and the button is pressed, it is determined that the person is sighted. As described above, the recognition means for detecting the tentacles includes the face plate part, a specific setting part on the face plate part, the touched place such as the button surface part, the order of the touched place, the touched time, and the tentacles to the landing button. The visually handicapped person is logically determined from the time until tentacle detection is started or after the tentacle detection is completed until the landing button is pressed. When it is determined that the user is visually impaired, the mode is shifted to the visually impaired mode. The elevator operation and mode cancellation in the visually impaired person mode will be described later.
[0046]
In addition, when a visually impaired person searches for a button, the touch on the face plate unit 6 may be stopped in order to stop using the elevator by changing his mind. It is assumed that there is a set time limit Tlimit for stopping and resetting the determination when it has not been touched or the stroke has not been pressed. In other words, Tlimit is a constant that determines whether to reset the judgment until the next time a sighted person enters the button operation after the visually impaired person stops the operation without pressing the button. Set it as a mode. In this embodiment, Tlimit is set to 3 seconds.
[0047]
Note that, as a premise, unless one person mistakenly operates, the stroke button is normally only pressed by one person, so that the logic judgment is reset every time the stroke button is pressed.
[0048]
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.
[0049]
In the figure,
A, C: Touch sensor circuit output
This is a general touch sensor button circuit that can recognize whether the button surface is touched by an induced current method.
Turn on when touching.
B, D: Stroke sensor circuit output
A general stroke button circuit in which the contact is turned on by pressing the button several millimeters.
Turn on when contact is connected.
E: OR output of A and C
F: OR output of B and D
[0050]
Here, in order to explain the logic flow shown below, E and F (OR circuit) are described, but in reality, each of the circuit output lines A, B, C, and D determines the logic. It is only necessary to calculate within the microcomputer, and there is no need for such an OR circuit outside the microcomputer.
[0051]
In addition, when the landing button is pressed directly, the output of the touch sensor circuit is turned on first, and then the output of the stroke sensor circuit is turned on.
[0052]
FIG. 4 shows one flow of the visually impaired person recognition circuit. In the figure, T is a timer, and Tlimit is a setting to stop and reset the judgment when a person has touched the button, but it has not touched or the stroke has not been pressed even if a certain time has passed after leaving the button. R represents a time limit, and R is a flag indicating whether or not both buttons have been touched. When both are touched, R = 1, otherwise R = 0.
[0053]
In the figure, S4 to S11 indicate cases where the upper button is first touched, and S15 to S21 indicate cases where the lower button is first touched. T count indicates that the time of T is counted.
[0054]
In the figure, when T> Tlimit (S11, S21), END (S25) is obtained, and when R = 1 (S22, S23), the visually handicapped person recognizes the user and the visually handicapped person driving mode. The elevator is operated by S24.
[0055]
FIG. 5 shows operations for mode setting and cancellation after recognition of the visually impaired. As shown in the figure, as an example, visually impaired person A gets on the second floor, registers the fifth floor, sighted person B who gets on the same floor registers the sixth floor, and sighted person C gets on the third floor and the seventh floor Indicates the case of registration. The 2nd to 6th floors are in visually impaired driving mode. The driving state in the viewer driving mode is shown on the right side of the figure.
[0056]
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 when the landing button that identifies the visually impaired person is pressed, the elevator in the called direction arrives, and the destination that is pressed on the operation panel in the elevator on that floor Suppose you arrive at the top floor (up) or bottom floor (down) of the floor button until the elevator door opens and closes. Cancel the visually impaired mode when closed. Even if it is recognized as a visually handicapped person, if there is more than one destination floor boarded by another person on the same floor and pressed in the elevator, specify which destination floor button the visually handicapped person pressed. This is because it is difficult.
[0057]
Identification is possible if a certain kind of visually impaired person recognition function is installed on the operation panel in the elevator.
[0058]
Next, an example of operation in the visually impaired driving mode is shown.
[0059]
As an operation on the elevator side when it is recognized as a visually handicapped person, physical machine control such as provision of voice guidance information in consideration of the visually handicapped person and door opening / closing time control is considered to be effective. Information that considers visually impaired people includes elevator operation status, explanation of operations and functions, floor guidance, people getting on and off, door opening and closing information, operation panel usability, current floor information during ascent and descent, emergency response information Etc.
[0060]
1) Extension of door opening time
The elevator door opening time will be extended more than usual so that visually impaired people can get on and off comfortably.
(Example) Normal 5 seconds → Visually disabled mode 15 seconds
[0061]
2) A fixed time standby function
Normally, if the destination floor is not registered even if the elevator is called and boarded, when the elevator is called on another floor, it will move to that floor. A visually impaired person is expected to take time to register the destination floor, and the elevator may move in such an unexpected direction. Therefore, in order to secure the time until the visually impaired person gets in and registers the destination floor of the operation panel in the elevator, the elevator is put in a standby state (waiting for destination floor input) for a certain time. The waiting is canceled when a certain time has elapsed or the destination floor is registered.
(Example) The fixed time is set to about 10 seconds.
[0062]
3) Platform audio additional guidance information
○ Time from when the platform button is pressed until the elevator arrives at the platform
Equipment configuration: Platform voice guidance device
-Information on the location where the target elevator is located for the landing button (if there are reciprocal units)
Why: If you use a single landing button to control multiple elevators, visually impaired people don't know where they are and which one goes to the target floor.
Example "Please wait for the elevator on the left"
・ Elevator operation floor information
Reason: If there are multiple elevators, the operation floor may be restricted. If the operation 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: Since the position of the operation panel in the elevator varies depending on the model, it is easy for visually impaired people to search for the operation panel by flowing position information.
Example “The control panel in the elevator is on the left side wall after entering”
・ Current operating status of elevators
Reason: Waiting for the elevator is anxious for the visually impaired. A sense of security is increased by notifying the current location as appropriate. In addition, in the case of a store or the like, it is possible to know what is on which floor by adding floor guidance.
Example “Elevator is currently stopped at the 3rd floor women ’s clothing department.
-Opening / closing doors, extended release time information, and getting-on / off warning information
Reason: By informing you that the opening time of the door will be extended, you can respond here mentally and comfortably.
Example “The door will be open for about 15 seconds.
"The door opens. Please be careful."
"The door has opened. Please be careful of the gap and gap"
・ Human information
Why: Visually impaired people don't know if anyone gets off before getting in and how the person moves. By notifying in advance that there are people getting off the elevator on that floor (it can be recognized from the fact that the destination floor has been reserved on the inside control panel), it avoids the trouble of accidentally colliding with the person getting off.
Example "There are people getting off on this floor. Please be careful"
[0063]
4) Elevator voice additional guidance information
When a visually handicapped person recognizes that he / she is an elevator user, the hall floor using the visually handicapped is detected from the destination floor button 11, and the platform guidance information is broadcasted by voice on the floor.
・ Information in the elevator
Equipment configuration: Elevator voice guidance device
・ Current floor, floor facility information
Reason: The display of the indicator cannot be recognized by visually impaired people, and it may be difficult to understand what is on the current floor or which floor. Also, if you know roughly the location of stairs and toilets that are useful in an emergency, you can feel secure.
Example “3rd floor ladies' clothing store. The stairs are on the right and the restroom is on the left.”
・ Emergency response information
Reason: It may be difficult for visually impaired people to understand when the elevator stops due to a malfunction.
Example “In an emergency, keep pressing the button on the top of the control panel.
・ Door opening / closing and getting-on / off warning information
Reason: You can get on and off mentally by notifying the door opening / closing information. It is possible to encourage safe boarding / exiting by notifying information on gaps and steps between the elevator and the hall.
Example “The door opens. Please be careful”
"The door has opened. Please be careful not to get off the steps or gaps."
[0064]
5) Elevator operation panel upper destination floor button flashing function
-The destination floor button pressed on the floor where the visually impaired person is identified blinks before the arrival of that floor (for example, from 2 seconds before arrival on the floor 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 low-sighted person, if the indicator is not visible in an elevator without voice guidance, it may be determined whether or not the destination floor has been reached rather than turning on and off the destination floor button that the user has pressed. By flashing the destination floor when arriving, it is possible to make it easier for low-sighted people to understand that the floor they pressed has arrived.
[0065]
6) Voice guidance warning chime
・ Sounds a chime to call attention that voice guidance will flow immediately before broadcasting important guidance that depends on voice for visually impaired people, such as arrival floor, door opening and closing, etc. by voice guidance in the elevator. The arrival forecast chime changes the tone. This prevents missed listening.
Example: Arrival floor "Chen" "3rd floor"
Door closed "Boo" "Door closes"
[0066]
7) Door open / close chimes
・ Even if there is a voice guidance for opening and closing the door, it may be difficult to understand when it closes and when it opens. Therefore, a suitable chime is sounded during the opening / closing operation. For example, a pleasant sound when opening. A little unpleasant sound like a buzzer when closing.
[0067]
FIG. 6 shows an operation flow when recognizing a visually impaired person.
[0068]
The operation flow when it is recognized as a visually handicapped person will be specifically shown based on several operation examples. Here, the difference between the visually impaired person mode and the normal mode is described so that it can be easily understood. In addition, functional examples of user behavior and elevator operation
(1) Extension of door opening time
▲ 2 ▼ Provision of additional voice guidance information
(3) Voice guidance alert chime
Show about. The detailed contents are as shown in the figure.
[0069]
FIG. 7 is a block diagram showing a configuration of an elevator system having a visually impaired driving mode.
[0070]
The landing-side system 41 includes a button switch 42, a microcomputer 43, and an audio output device 44 for each floor. Each elevator 45 includes an audio output device 46, a door opening / closing control device 48 for door opening / closing control 47, and a microcomputer 49. 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.
[0071]
The sound device includes a sound effect output such as a warning sound in addition to the sound. With this configuration, it is possible to realize all operation examples in the visually impaired person mode.
[0072]
Unlike the middle floor, the top and bottom floors operated by the elevator have a single landing button, so that the conventional recognition methods cannot identify visually impaired persons. Therefore, for these floors, please refer to the recognition system as in the third embodiment.
[0073]
8 and 9 show a second embodiment of the method for automatically recognizing the visually impaired.
[0074]
FIG. 8 is a button circuit sensor diagram. In this example, a touch sensor 51 is provided on the face plate portion 6. The touch sensor 51 searches for the function of the face plate portion 6 in the previous embodiment. That is, the touch sensor 51 constitutes a part of the face plate portion 6. In this case, the face plate unit 6 and the touch sensor 51 may be ANDed. As the touch sensor, a commonly used sensor such as an induced current type, an infrared detection type, a micro switch type, or the like is used. Therefore, tentacle detection includes both the case where the hand is touched directly and the case where the hand is touched indirectly.
[0075]
The visually impaired person touches the face plate portion 6 and then touches the touch sensor 51 provided between the two stroke buttons 52.
[0076]
In the figure,
A, B: Stroke sensor circuit output
A general stroke button circuit in which the contact is turned on by pressing the button several millimeters.
Turn on when contact is connected.
C: Touch sensor circuit output
A general touching state that can recognize whether or not the button surface is touched by an induced current method or the like is set to ON.
D: A or B stroke or output
When attention is paid to the action principle and application of the button search for the visually impaired and the example (4) of the recognition pattern of the button of the visually impaired, in this recognition pattern, the upper and lower buttons are always touched. Therefore, a touch sensor 51 is provided between the two buttons on the face plate portion, and it is determined whether the person is visually impaired or not based on information touched on this part and information on pressing the button (and time relationship). ing.
[0077]
Here, in order to explain the logic flow shown below, D (Ao circuit) has been described, but in reality, each of the circuit output lines A, B, and C determines the logic (such as a timer). It is only necessary to be calculated in the microcomputer, and there is no need for such an OR circuit outside the microcomputer.
[0078]
FIG. 9 shows a flow of the visually impaired person recognition circuit. The flow includes steps from S31 to S39.
[0079]
In the figure, T is a timer, and Tlimit is a setting for stopping and resetting the judgment when a person touches the touch sensor unit and does not touch even after a certain period of time has passed since it was released, or when the stroke is not pressed Time limit. Since the touch sensor part is limited, it may be possible to touch a face plate part or button other than this part, so it is set a little longer. Here, Tlimit = 20 seconds is set.
[0080]
Although this method is implemented with a simpler circuit than that of the first embodiment, there is a high possibility that even a sighted person will casually touch the touch sensor unit, and the probability that it can be determined as a visually impaired person may be lower than that of the first embodiment. There is sex.
[0081]
10 and 11 show a third embodiment. FIG. 10 shows a button circuit sensor.
[0082]
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 in the second embodiment. 62 is a stroke button.
[0083]
The lowest floor landing button is configured as shown in FIG. 11, and a touch sensor 61 and a stroke button 62 are provided as in FIG.
[0084]
In the method of the third embodiment, the following various variations can be considered as a method of not identifying a portion that is difficult for a sighted person to touch as a touch sensor unit, and specifying a portion that is easily touched by a visually impaired person. By adopting such a variation, it can be combined with the recognition method described above, and the recognition rate with the visually impaired can be increased.
[0085]
FIG. 12 is a button circuit sensor diagram according to the fourth embodiment.
[0086]
When a visually handicapped person locates the face plate portion 6 and then searches for a landing button 7 on the face plate portion, a hand that is fixed as a reference for finding the button touches the edge (end surface portion) 71 of the face plate portion. This portion is referred to as a touch sensor unit 72. And if it is more than a certain fixed time after touching this part until a stroke button is pushed, it will discriminate | determine from a visually impaired person. 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.
[0087]
FIG. 13 is a button circuit sensor diagram according to the fifth embodiment.
[0088]
When the visually handicapped person locates the face plate portion 6 and then looks for the landing button 7 on the face plate portion, the position of the button is located so as to slide his / her finger, that is, the action reaches the button with a substantially continuous locus. Paying attention, let the peripheral part 74 of the button be the touch sensor 74. (A) shows an example of a square button, and (B) shows an example of a round button. Then, after touching this portion, it is determined that the person is visually impaired when the stroke button is pressed. By narrowing the range, it is possible to increase the probability that a sighted person will not discriminate a sighted person from being visually impaired even if the sighted person naturally touches the face plate portion 6. The logic flow diagram is the same as in the second embodiment. This example is also valid for the buttons on the top and bottom floors.
[0089]
FIG. 14 is a button circuit sensor diagram according to the sixth embodiment.
[0090]
Although there is an idea that the Braille nameplate part is a touch sensor part, a sighted person often touches the Braille nameplate in an interesting way, and it is difficult to distinguish it as it is.
[0091]
Therefore, paying attention to the action of a visually handicapped person who searches for Braille while touching, a touch sensor unit 76 is provided between or around the upper and lower Braille nameplates 75. Then, after touching this portion, it is determined that the person is visually impaired when the stroke button is pressed. Even if the sighted person touches his interest, it is considered that he / she touches only the braille nameplate part and does not touch this touch sensor part.
[0092]
It is also possible to increase the probability of discrimination by providing a touch sensor unit that can be detected independently in the braille name plate unit and calculating the information touched by each. The logic flow diagram is the same as in the second embodiment.
[0093]
15 and 16 show the automatic recognition and operation of the visually impaired in the elevator. FIG. 15 is a destination floor button circuit sensor diagram.
[0094]
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, it is automatic recognition and operation of visually impaired people in the elevator hall, but after getting into the elevator, paying attention to the search action of visually impaired people who specify destination floor etc., if the destination floor button can be recognized automatically, Identifying visually impaired people when they are pressed, the inside of the elevator may be dark, so if people with low vision perform the same search act, the range that can be identified as visually impaired people can be expanded, and more visual A means for improving the usability of the elevator can be provided to persons with disabilities.
[0095]
The principle of automatic recognition can be determined by applying the embodiment at the landing button. For example, as in the first embodiment, the touch sensor + stroke sensor button is used as the destination floor button of the operation panel in the elevator. Visually handicapped people (people who do not read Braille), for example, from the lower left, 1, 2, 3 ...・ Search sequentially. For this reason, it often touches a plurality of adjacent destination floor buttons.
[0096]
Therefore, based on the relationship between the information that touched the destination floor button and the information that was subsequently pressed by the stroke and the time, it touched multiple (sequential) destination floor buttons within a certain time, and then the button pressed. If it is determined, the destination floor button can be determined as the destination floor for the visually impaired.
[0097]
FIG. 16 shows a flow of the visually impaired person recognition circuit. The flow consists of steps S41 to S52.
[0098]
In the figure,
J is a primary matrix that stores SN (different from the previous one).
Let S be (ON) output information touched as a touch sensor.
(SN is the floor of the touched destination floor button)
Let P be the output information that the destination floor button is pressed by a stroke.
(PN is the floor of the pressed destination floor button)
T is a timer. Tlimit is a set time limit for stopping and resetting when a person touches the button and does not touch it after a certain period of time after it is released or when the stroke is not pressed.
[0099]
Here, Tlimit = 3 seconds is set.
[0100]
When the second SN from the end of the stored primary matrix J is (PN + 1) or (PN-1) in the comparison of P and J, that is, the comparison with the set condition (S50) (ie, the button pressed) If you touch the button on the upper or lower floor just before), set YES. Otherwise NO. That is, it is recognized as a visually impaired person.
[0101]
(Example) P_N= 6, J = (6) → sighted person
P_N= 6, J = (12,6) → sighted person (may have touched the 12th floor button to press the 6th floor)
P_N= 6, J = (2, 1, 2, 3, 4, 5,6) → Visually impaired (touching the 5th floor button before pressing the 6th floor)
[0102]
In this way, when it is recognized as a visually handicapped person in the automatic recognition of the operation panel in the elevator, it is set to the visually handicapped person mode from that point and is shown in `` Operation example in the visually handicapped person mode '' when recognized with the landing button Shall perform the same operation.
[0103]
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 the arrival at the destination floor set above and the door opening and closing.
[0104]
If a voice guidance device is provided, the following functions can be added. That is, when a plurality of destination floor buttons (for example, three or more) are touched within a certain period of time without a stroke being pressed on the destination floor button of the operation panel in the elevator, the touching person is visually impaired. If you recognize that you are a person with a high probability, and then output the number of the floor of the button you ’re touching, you can know which destination floor button you ’re touching. It will be possible to find the button of the button accurately and quickly.
[0105]
Of course, if the destination floor is pushed after the search, it is certainly not convenient if a voice guidance such as “I registered the 6th floor” appears.
[0106]
In addition to the above, regarding the method of recognizing visually impaired persons on the operation panel in the elevator,
・ When the destination floor button is a touch sensor & stroke button and the button is pressed after touching more than one (for example, three) or more buttons
・ When the button is pressed after touching the entire faceplate part of the operation panel in the elevator for a certain period of time
・ When the button is pressed after touching the face plate between the braille nameplates as a touch sensor
・ When the braille nameplate is used as a touch sensor and the button corresponding to the braille is pressed after touching the braille
Can be recognized as a visually impaired person.
[0107]
【The invention's effect】
According to the present invention, a tentacle state with respect to a face plate that a visually handicapped person first touches and continuously touches with one hand is detected. Since the condition that the visual injured person is the user is recognized when there is an AND signal, the time until the operation button is pressed is further calculated logically. Because it is determined that the visually handicapped person is a user according to the behavior of the operation button search of the visually handicapped person, automatic recognition of the visually handicapped person is performed. It will be done reliably. Along with this, it is possible to shift the elevator operation to the visually impaired driving mode with a high recognition rate, so services such as extended door opening time, provision of additional voice guidance information, and voice guidance warning chimes are ensured. To be able to do it. As a result, it is not necessary to reduce the driving efficiency during normal driving by the visually impaired driving mode, and it is possible to reduce voice noise to surrounding people.
