Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a call registration device for an elevator.

(Prior Art) Conventionally, elevator halls are generally provided with a call registration button for the ascending direction and a call registration button for the descending direction. If the target floor is above the current floor, I had to press the direction call registration button, and if it was down, I had to press the descending call registration button. Therefore, if you are carrying luggage etc. with both hands, you have to lower the luggage once and operate the call registration button, and also when you enter the elevator car, press the destination floor button as well. There was the inconvenience of having to push down the luggage and then push it.

In view of such problems, in recent years, voice recognition technology for recognizing the voice of an unspecified speaker has improved, and a microphone has been installed in an elevator hall, and the voice recognition recognizes the ascending direction, the descending direction, and the destination floor. An elevator call registration device that enables call registration has been proposed.

(Problems to be Solved by the Invention) However, even in such an elevator call registration device using voice recognition, the environment of the elevator hall cannot necessarily be said to be a good environment for inputting voice, and the elevator waiting The microphone picks up voices and noises from places other than the customer's conversations and elevator halls, which lowers the recognition rate and makes incorrect call registration, causing the elevator to perform useless driving and deteriorate driving efficiency. There was a problem that made the service worse.

The present invention has been made in view of the above conventional problems, and it is possible to prevent a decrease in voice recognition rate due to noise, reduce erroneous call registration, and improve operation efficiency of an elevator call registration device. The purpose is to provide.

[Structure of the Invention] (Means for Solving the Problem) An elevator call registration device of the present invention includes a microphone installed in an elevator hall and a person who detects whether or not an elevator user stands in front of the microphone. The voice signal input to the microphone is compared with the voice registered in advance only when there is a person detecting signal from the person detecting means and the person detecting means, and when the voice signal matches the registered voice, the call registration signal is generated. And a voice recognition means for uttering.

(Operation) In the elevator call registration device of the present invention, when the call is registered by the microphone installed in the elevator hall, the person detecting means detects whether or not the elevator user is standing in front of the microphone, and The voice recognition means is enabled only when the detection means detects that the elevator user is standing in front of the microphone, and the voice signal input through the microphone is compared with the pre-registered voice, and both voice signals are compared. When the two match, the elevator call registration signal can be issued.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows the appearance of the elevator hall 1, which includes an elevator door 2, a position indicator 3, a hall call registration button 4, a microphone 5 for giving a voice input, and a human detection device 6 including an ultrasonic sensor.
A voice call registerable indicator lamp 7 is provided to indicate to an elevator user whether voice call registration is possible.

FIG. 1 is a block diagram showing a circuit configuration of such an elevator call registration device. In addition to the microphone 5, the person detection device 6, and the voice call registerable indicator lamp 7, a voice input signal 5a from the microphone 5 is input. A voice recognition device 8 as an input, a call registration device 9 that performs a call registration by the output from the voice recognition device 8, and an elevator control computer that controls the operation of an elevator by a signal from the call registration device 9.
Equipped with 10. And this elevator control computer
An elevator driving motor 11 is driven by 10 so that the elevator car 12 and the counterweight 13 are moved up and down.

The operation of the elevator call registration device having the above configuration will be described below.

In FIG. 1, the voice input signal 5 a input by the microphone 5 is input to the voice recognition device 8. Also,
When a person is detected by the person detecting device 6, a person detecting signal 6
Each of a and 6b is output from the human detection device 6 and input to the voice recognition device 8 and the voice call registerable indicator lamp 7.

The voice call registerable indicator lamp 7 lights up when the person detection signal 6b from the person detecting device 6 is input.

When the voice input signal 5a is input while the human detection signal 6a is being input, the voice recognition device 8 performs a comparison operation with a registered voice that has already been registered. When 6a is not input, comparison operation is not performed.

A human detection signal 6a is input from the human detection device 6 to the voice recognition device 8 and a voice input signal 5a is input from the microphone 5.
Is input, a comparison is made with the pre-registered voice, and if the registered voice and the input voice match, the call registration permission signal 8a corresponding to the matched voice input signal 5a is registered for call registration. It is output to the device 9.

The call registration device 9 receives the call registration permission signal 8a and outputs the call registration signal 9a to the hall call registration button 4,
The call registration signal 9b is output to the elevator control computer 10.

When the call registration signal 9a is input, the hall call registration button 4 lights up the call registration light in the ascending direction or the descending direction according to the call registration signal 9a.

Further, the elevator control computer 10 is provided with a call registration signal 9b to control the elevator drive motor 11 to cause the elevator car 12 to respond to a hall call for which call registration has been performed as in the conventional case. Then, when the hall call elevator car 12 responds, the elevator control computer 10 outputs a call registration deletion signal 10a to the call registration device 9.

The call registration device 9 receives the call registration deletion signal 10a from the elevator control computer 10, and receives the call registration signals 9a and 9b.
Is stopped, the hall call registration button 4 is turned off, and the hall call registration is deleted.

It should be noted that the hall call registration button 4 can directly enter the button call registration signal 4a into the call registration device 9 to establish the call registration regardless of the time when the push button is pressed.

Further, the operation of the elevator call registration device will be described based on the flowchart shown in FIG. 4. An elevator user comes to the elevator hall 1 and the microphone 5
When standing in the detection area A in front of, the human detection device 6 composed of an ultrasonic sensor outputs the human detection signals 6a and 6b to the voice recognition device 8 and the voice call registerable indicator light 7, respectively (step S1).

Upon receipt of the person detection signal 6b, the voice call registerable indicator lamp 7 displays the voice call registerable as shown in FIG. 3 (step S2).

Further, the voice recognition device 8 receives the human detection signal 6a, becomes ready for comparison operation, waits for the voice input signal 5a from the microphone 5 to be input (step S3), and the voice input signal 5a from the microphone 5 is input. Then, it is compared with the already registered voice, and if there is a voice match, the voice call registration permission signal 8a corresponding to the input voice input signal 5a is output to the call registration device 9 (step S4, S5).

In other words, the microphone 5 is the elevator hall 1 on the first floor.
When a person stands in the detection range of the person detection device 6 on the first floor and the voice (upper) already registered in the voice recognition device 8 is input from the microphone 5, the first floor ascending direction call The registration permission signal 8a is input to the call registration device 9,
The call registration device 9 supplies the first floor ascending direction call registration signal 9a to the call registration button 4 to turn on the ascending direction call registration light. At the same time, the call registration device 9 gives a first floor ascending direction call registration signal 9b to the elevator control computer 10 and causes the elevator car 12 to respond to the first floor call.

Then, when the elevator car 12 responds to the first floor, the elevator control computer 10 outputs an ascending call registration deletion signal 10a on the first floor to the call registration device 9, and the call registration device 9 outputs this call registration deletion signal 10a. In response to this, stop outputting the first floor ascending direction call registration signals 9a, 9b that had been output until then,
Turn off the ascending direction call registration light on the first floor and delete the ascending direction call registration on the first floor.

In step S1, when the human detection signal 6a from the human detection device 6 is not input to the voice recognition device 8, the comparison operation of the voice recognition device 8 is prohibited and even if the voice input signal 5a is given from the microphone 5. , No comparison operation is performed (step S6).

If the voice input signal 5a from the microphone 5 is not input in step S3, step S4
Even if the voice input signal 5a from the microphone 5 does not match the voice registered in advance, the voice call registration is not performed.

In this way, the person detection device 6 detects whether or not a person is standing in front of the Mimarophone 5 for voice input in the elevator hall 1, and only when the person is standing in front of the microphone 5, voice call registration is performed. By making it possible, it is possible to prevent the voice recognition device 8 from performing the call registration operation only with the voice input signal from the microphone 5, and avoid unnecessary driving of the elevator.

In addition, although the ultrasonic sensor is presented as the human detection device 6 in the above embodiment, the human detection device is not limited to that of the embodiment, and the following system may be used. it can.

This is a method to detect infrared rays and far infrared rays emitted by the human body by configuring a human detection device with a device that detects infrared rays and far infrared rays.
