With this arrangement, in an elevator call registering device 8, when one of voices from the microphones 5, 6 is detected, the voice recognizing device 7 compares the voice with voices registered beforehand, and delivers a demanded call registered signal when the voice coincides one of them and a hall call or a cage call can be registered in accordance with this call registered signal.

Description

[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention relates to an elevator call registration device.

(Prior Art) Conventionally, elevator halls are generally equipped with a hall call registration button for the ascending direction and a hall call registration button for the descending direction. I had to press the upbound call registration button. Therefore, if you are carrying luggage with both hands, you must first put down your luggage before operating the call registration button, and even if you are inside the elevator car, you must press the destination button in the same way. There was the inconvenience of having to unload the baggage and then push it.

In view of these problems, in recent years, voice recognition technology that recognizes the voices of unspecified speakers has improved. Elevator call registration devices that enable call registration by direction and destination have been proposed.

(Problem to be Solved by the Invention) However, in such conventional elevator call registration devices, the microphone, which is a voice input device for voice recognition, is installed at a height that matches the height of an adult. For short children and disabled people in wheelchairs, the mouth and microphone are too far apart, making it difficult for the voice to reach the microphone clearly, making it difficult to recognize the voice or causing misunderstandings.

In addition, in recent years, houses in urban areas have become high-rise buildings, and it has become impossible to go outside without using an elevator. Children who frequently go out to play are often too tall or short to take elevators. There are cases where people are unable to press the call button and are unable to leave the house. Therefore, lowering the mounting height of the button for children would result in a position that would be difficult for adults to use, and providing two sets of buttons would be a huge loss in terms of space and cost. It was hoped that a device would emerge that would allow even children to easily register their calls.

This invention was made in view of the above-mentioned conventional problems, and it is possible to use two or more microphones (one for adults and one for children/disabled persons), which are voice input devices when registering calls by voice recognition, at different heights. It is possible to improve services and improve usability for users by installing them differently.
The purpose of this invention is to provide a call registration device for /heta.

[Structure of the Invention] (Means for Solving the Problems) The elevator call registration device of the present invention has a plurality of microphones installed in an elevator landing or in an elevator car at a height that allows an adult to manually input and a height that allows a child to input. A voice recognition device that manually inputs the voice from these microphones, compares it with the registered voice, and issues a required call registration signal when the voice signal matches the registered voice. It has been established.

(Function) In the elevator call registration device of the present invention, there are multiple microphones at different heights as voice input devices for voice call registration, and when one of the microphones detects a voice, the voice recognition device The input voice is compared with the voice registered in advance, and when a matching voice is found, a required call registration signal is issued, and the hall call or car call is registered based on this call registration signal. I can do it.

(Example) Hereinafter, one embodiment of the present invention will be explained in detail based on the drawings.

FIG. 2 is an external view of an elevator hall for explaining the arrangement of main elements constituting one embodiment of the present invention. In the figure, there is an elevator door 2 in front of an elevator hall 1, a position indicator 3 is provided on the upper part of the elevator door 2, and a hall call registration button 4 is provided on the right side. In addition to registration using the hall call registration button 4, in order to enable registration by voice recognition, an average adult above the hall call registration button 4 can input voice without taking an unnatural posture. An adult microphone 5 is provided at a high position, and a child microphone 6 is provided at a low position below the hall call registration button 4.

FIG. 1 is a block diagram showing the overall configuration of the above embodiment. In the figure, a voice input signal 5a of an adult microphone 5 and a voice input signal 6a of a child's microphone 6 are input to a voice recognition device 7. When the voice recognition device 7 receives a voice signal input from the adult microphone 5 or the child microphone 6, it inputs only the voice signal received first and ignores the voice signal received later. ing.

Voice data is registered inside this voice recognition device 7, and when a voice input signal 5a or voice human input signal 6a is input, it is determined whether or not the human voice and the registered voice match, and when they match, the voice data is registered. A call registration permission signal 7a corresponding to the voice is given to the call registration device 8. The call registration device 8 receives the call registration permission signal 7a, adds a call registration signal 8a to the call registration button 4, and further gives a call registration signal 8b to the elevator control computer 9, so that the elevator responds in response to the call registration. It is designed to take control. Note that the call registration signals 8a and 8b can be deleted by the call registration deletion signal 9a from the elevator control computer 9.

The elevator control computer 9 is an elevator drive motor 1
The operation can be controlled by controlling 0 and raising/lowering/stopping the elevator car 12 having a counterweight 11.

Next, the operation of the elevator call registration device configured as described above will be explained according to the flowchart of FIG. 3.

An elevator user comes to the elevator hall 1 and receives voice input from the adult microphone 5 (step 101). In this way, the audio input signal 5a from the adult microphone 5
When inputted, the speech recognition device 7 prohibits the human input of the voice input signal 6a from the child's microphone 6 (step 102).

Next, the voice recognition device 7 compares the already registered voice and the human voice, and if there is a match, a voice call registration permission signal 7a corresponding to the human voice signal 5a.
is output to the call registration device 8 (steps 103, 104
).

In addition, the audio input signal 6 from the children's microphone 6 is first
When a is input (step 105), the speech recognition device 7
input of the audio input signal 5a from the adult microphone 5 is prohibited (step 106).

Then, in the same way, the voice recognition device 7 compares the already registered voice and the input voice, and if the voices match, it sends a voice call registration permission signal 7a corresponding to the input voice human input signal 6a. It is output to the call registration device 8 (steps 103 and 104).

In this way, for example, when the adult microphone 5 and the child microphone 6 are installed in the elevator landing 1 on the second floor, the adult microphone 5 can be connected to the voice recognition device 7.
When the voice "Ue" already registered in is input, the voice recognition device 7 sends a second floor ascending direction call registration permission signal 7a.
is manually input to the call registration device 8, and the call registration device 8 gives a second floor upward direction call registration signal 8a to the call registration button 4, and lights up the upward direction call registration light. At the same time, the call registration device 8 provides the second floor ascending direction call registration signal 8b to the elevator control computer 9 to cause the elevator car 12 to respond to the second floor call.

When the elevator car 12 responds to the second floor, the elevator control computer 9 outputs a call registration deletion signal 9a for the ascending direction of the second floor to the call registration device 8, and the call registration device 8 receives this call registration deletion signal 9a. Then, the output of the second floor up direction call registration signals 8a and 8b that had been outputted until then is stopped, the second floor up direction call registration light is turned off, and the second floor up direction call registration is deleted.

In this way, it is possible to register a call by voice from either of the two microphones, the adult microphone 5 and the child microphone 6, provided in the elevator hall 1. When one microphone is inputting audio,
By prohibiting voice input to the other microphone so as not to pick up noise, it becomes possible to improve the recognition rate of voice calls.

In this way, according to this embodiment, even short children and people with physical disabilities can register a call by voice without having to take an unreasonable position, and the recognition rate is improved, resulting in a marked improvement in service compared to conventional devices. It can be planned.

[Effects of the Invention] As described above, according to the present invention, since the microphones are provided at multiple locations at different heights, children of short stature and persons with disabilities, who had difficulty registering calls in the past, can easily register calls. This makes it easier for users to use and improves services.
