Abstract

PURPOSE: To effectively prevent the operation of an elevator car to the direction, not intended by a passenger, by maintaining a priority response direction for a required time during registration even if a time is required for car call registration. CONSTITUTION: A microphone 10 used to register a voice call inputs a voice signal 10a to a voice recognizing device 11. A detecting switch 12 is a foot- operated switch, e.g. to show that a passenger wants to register his/her voice. An indicator 13 to indicate the registered voice shows contents, depending on circumstances. A timer count control means 21 and a call register means 22 output effective signals 22a to the voice recognizing device 11. The decision of an operating direction is based on a car call button and a landing call button 1. In this case, when operation by the call register means 22 is being detected by the timer count control means 21, a priority response direction based on the landing call button 1 is maintained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device including door registration as well as elevator call registration.

[0002]

2. Description of the Related Art It is well known that an elevator is operated by operating a hall call button provided in a hall and a car call button provided in a car.

At the elevator hall, as shown in FIG.
In general, a hall call button 1 is provided for the ascending direction and the descending direction, and a car call button 2 for each target floor is generally provided in the elevator car as shown in FIG.

FIG. 4 is a diagram showing an entire control program of an elevator controller using a microcomputer. First, there is a timer counter control built in the microcomputer, and then there is an input process for reading external inputs such as call buttons and sensors. After that, the operation mode is determined, the call registration based on the hall call and the car call is performed, the operation direction of the elevator car is determined, the traveling control judgment of the elevator car is performed, the door control judgment is also performed, and finally these judgments are made. Based on the result, the control device is designed to repeatedly execute a series of control program flows of performing output processing to the control device.

Here, in order to understand how the driving direction of the elevator is determined based on the call registration,
Details of the timer counter control flow, the call registration flow, and the driving direction determination flow are shown in FIGS. 5, 6, 7, 8, and 9. However, for simplicity, only a part is shown.

First, in FIG. 5, in the T-DO control unit,
When the elevator car door is at the door open completion position, the door open timer preset to a predetermined value is decremented according to the elapsed time, and the elevator car is stopped in the T-PR-D control unit. , And when the elevator car door is not in the door-opening operation, the priority response direction PR-D holding timer (a timer that holds the direction in which the passenger wants to go is set as the priority direction for a predetermined time) that is preset to a predetermined value is elapsed time. Shows the flow of subtraction according to.

FIG. 6 is divided into a car call registration section when the car call button 2 is operated and a hall call registration section when the car call button 1 is operated. Particularly, in the case of a hall call, priority response is given. If the direction PR-D is UP, the ascending landing call is canceled, and if the priority response direction PR-D is not UP and an ascending landing call is operated, the ascending landing call is registered and described later. It will be connected to the driving direction decision flow of.

Next, FIGS. 7 to 9 are flow charts showing how to determine the priority response direction PR-D depending on whether the elevator car is stopped, decelerated, or traveling at a constant speed. Is.

[0009] Whether the priority response direction PR-D is going up (UP) or going down (DN) is determined according to the situation of a car call and a hall call. Especially, when the elevator car is stopped, the call input state Not only sets the priority response direction PR-D in the ascending direction (UP) or the descending direction (DN), but also sets the holding timer to a predetermined value (for example, 5 seconds).

Such a call registration flow and a driving direction determination flow need not be described in detail, and they are conventionally known and are well known.

Here, the elevator car called by operating the hall call button 1 has a priority response direction corresponding to the hall call for a predetermined time even after reaching the floor. That is, when the passenger calls in the ascending landing call, the driving direction is the ascending direction (UP), and when the landing call is in the descending direction, the driving direction is the down direction (DN). It is maintained during operation, and is designed so that the elevator car that has been called up will not be driven in an unintended direction.

[0012]

However, in the case of an elevator that performs car call registration using a voice recognition device, for example, it may be necessary to reconfirm the recognition contents due to the limit of the performance of the recognition device. Therefore, it may take a longer time than usual to complete the car call registration (a time exceeding about 5 seconds required for passengers to board). In such a case, as a result of the maintenance of the priority response direction being canceled, the elevator may respond to another hall call and may carry the passenger in the car in an unintended direction.

The present invention has been made in view of the above points,
An object of the present invention is to provide an elevator control device that reliably transports passengers to a destination floor.

[0014]

The present invention comprises a car call registration means provided in an elevator car and a hall call registration means provided in a hall, and the driving direction is determined based on the both registration means.

Things.

[0015]

With the above-described structure, the elevator is driven in the direction that is in line with the passengers calling the hall.

[0016]

An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of an elevator car equipped with a voice recognition device, FIG. 10 is an overall configuration diagram showing an embodiment of the present invention, FIG. 11 is a flow chart diagram showing a flow of timer count control according to the present invention, and FIG. Is a flow chart showing a car call registration means by the voice recognition device 11 according to the present invention, FIG. 13 is a flow chart diagram showing a display state by the display device 13 according to the present invention, and FIG. 14 is a driving direction determination means 22 according to the present invention. It is a flowchart figure which shows a flow.

In the drawings, the same reference numerals and the same description as in FIGS. 2 to 9 indicate the same things, but 10 is a microphone for call registration by voice, and a voice signal 10a is input to a well-known voice recognition device 11. It has become so. Reference numeral 12 denotes a detection switch such as a mat switch which the passenger operates with his / her foot in order to indicate his / her intention to register by voice. Here, the operation indicating the intention of registration is included in order to prevent the inconvenience that the voice recognition device erroneously processes a normal talking voice or other noises as a call registration voice.

Reference numeral 13 is a display device for performing a display related to voice registration. Specifically, as shown in FIG. 13, display contents corresponding to the situation are displayed. Reference numeral 21 is a timer count control means according to the present invention, and 22 is a call registration means according to the present invention, which outputs a later-described valid signal 22a to the voice recognition device 11.

As can be seen from FIG. 11, in the timer count control flow according to the present invention, a recognition continuation monitoring timer "T-RC" control unit and a display continuation timer "T-
A "DSP" controller has been added.

According to the call registration flow by voice recognition shown in FIG. 12, if the car is stopped at an arbitrary floor, it takes about 30 seconds from the state where the mat switch 12 is stepped until the car call registration process is completed. Until (the recognition continuation monitoring timer "T-RC" times out), it is determined that the voice call registration operation is in progress, and the valid signal 22a is transmitted to the voice recognition device 1.
1 is output to voice recognition processing.

The completion of the car call registration process means that the car call registration is completed if the temporarily registered floor that is temporarily registered is displayed on the display device 13 and a response is received to confirm whether or not it is correct. On the other hand, in the case of the voice recognition device 11, the time of 30 seconds is a reasonable maximum time for finally registering as a car call including confirmation of the user and response to it. Say the time you can think of.

Then, in the driving direction determining means, as shown in FIG. 14, a flow for determining whether or not a voice call registration operation is being performed is added to FIG. 7, and if it is being operated, the priority response direction is deleted and changed. I decided not to do it.

Therefore, during the voice call registration operation, the elevator car called to the hall call remains in the priority response direction PR-D based on the hall call, and therefore answers the other hall calls. Therefore, the elevator will not be driven to the floor against the passengers' will.

Even during the voice call registration operation,
If it exceeds 30 seconds or the voice recognition state is released, the driving direction is determined so as to cancel the hold of the priority response direction during the stop and promptly answer another call. ing. This is to prevent the wrong priority response direction from being continuously maintained when the mat switch 12 itself fails or the passenger inadvertently depresses the mat switch 12.

Here, the flow of car call registration by voice recognition shown in FIG. 12 will be described below step by step. The flow of FIG. 12 is a flow additionally inserted in the α part of the call registration flow shown in FIG.

First, it is constantly checked whether or not the mat switch 12 is ON (the mat switch 12 is stepped on), and if it is OFF, the OFF confirmation flag is always set (ON). This is the mat switch 12
By activating the voice recognition device 11 only when the switch turns from OFF to ON, the priority response direction is unnecessarily held every time the car stops even if the mat switch 12 fails and remains in the ON state, for example. The purpose is to prevent inconvenience.

That is, the elevator car is stopped at the floor level, and the mat switch 12 is in the ON state.
If the FF confirmation flag is in the ON state, it means that the mat switch 12 has changed from OFF to ON for the first time. Therefore, the valid signal is turned ON and the valid signal 22a is sent to the voice recognition device 11 as shown in part A of FIG. Is input, and the recognition continuation monitoring timer “T-RC” is initialized (about 30 seconds as a guide). Then, the OFF confirmation flag is set to the OFF state.

After this, since the OFF confirmation flag is in the OFF state, the flow shifts from the A section to the B section, and the voice is recognized from the voice recognition device 11 until the recognition continuation monitoring timer "T-RC" is set to 0. First, the floor name is set as the temporary registration floor, it is determined whether the recognition of the temporary registration floor is correct, and if the determination is affirmative, the temporary registration floor is registered as the destination floor. It is possible to define that the voice call registration operation is in progress by combining the flows of the parts A and B.

Next, if the temporary registration floor is erroneously recognized, the temporary registration floor is first erased, and the voice recognition is performed again. And in the unlikely event that the recognition continuation monitoring timer "TR
When "C" is up, the valid signal 22a is removed and the voice call registration operation is ended. That is, the voice recognition operation is ended.

The recognition phases = 1 to 10 shown in FIG. 12 are phases for distinguishing each state of the voice recognition device 11, and this is succeeded to the flow showing the display contents of the display device 13 shown in FIG. 13 below. is there.

In FIG. 13, the display continuation timer "T-
The "DSP" is set to about 2 seconds, and a program is built so that the display content once determined is retained for a minimum of 2 seconds.

When the temporary registration is made, the display device 13 displays "X
Register the floor. Are you sure? ”Will be displayed to ask the passenger for confirmation, and the floor name will be checked for correctness by voice recognition by answering“ yes ”and“ no ”. Will be seen.

The registered floor confirmation means may be a means for confirming by voice instead of the display, and is not particularly limited to the embodiment.

Since the control flow of the elevator car door is slightly different from the conventional one, it will be described below with reference to FIG.
The part that differs from the conventional control flow is the door-opening timer "T-DO" shown in part C (normally set to about 5 seconds).
Is only the part where a flow for determining whether or not a voice call registration operation is being performed is added to the flow after the time is up.
The broken line indicates the conventional case, and the solid line indicates the present invention.

That is, when the door open timer "T-DO" counts down to 0, the car door is immediately closed in the case of the conventional elevator (if it is closed, the door drive motor is stopped). In the case of an elevator equipped with this voice recognition device, after determining whether or not a voice call registration operation is in progress,
If the voice call registration operation is not in progress, the door will be controlled as before, but if the registration operation is in progress, the door will be kept open (or opened if the door is not fully open). However, it does not respond to other calls.

In the flow shown in FIG. 15, the portions similar to the conventional ones are well known and the detailed description thereof will be omitted.

The car call registration based on the voice recognition is not only suitable for the visually impaired and physically handicapped, but also
This system is extremely useful for passengers who cannot hold their hands because even a healthy person has the luggage in both hands.

In the above description, the car call registration means by voice recognition has been described. However, even if the car call registration means is carried out through a plurality of operating procedures such as the operation of the recitation button by the ten key operation, it takes time. It is obvious that the present invention can be implemented to obtain the effects of the present invention. Therefore, it is not limited to the car call registration means by voice recognition. Also, an example in which a mat switch is used as a means for indicating the passenger's intention to register by voice has been described, but the invention is not limited to the embodiment because it may be a means such as a large push button that can be easily pressed by an elbow.

[0039]

As described above, according to the present invention, even if it takes some time to register a car call, the priority response direction is maintained for the required time during the registration operation, so that the direction not intended by the passenger is provided. It is possible to very effectively prevent the elevator car from being operated. Further, during the registration operation, the passengers can be accurately informed of the current situation, so that the time until the completion of registration can be shortened.
