Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice guidance device for an elevator hall.

[0002]

2. Description of the Related Art In recent years, a large number of devices have been used to improve the environment in which elevators are used as vertical transportation for buildings such as high-rise buildings. In particular, there is an increasing tendency to increase the number of devices that notify passengers of information by sound. Currently, the following are examples of the notification contents. (A) Voice guidance (b) Registration sound during call registration (c) Chime sound indicating arrival at the destination floor (d) Warning buzzer sound when the loaded load is exceeded (e) Buzzer sound indicating door closing operation Now, as one of the group management services for efficiently controlling a plurality of elevators, voice guidance in elevator halls has come to be performed.

FIG. 4 shows the appearance of an elevator hall provided with such various notification means. First, the waiting customer 7 operates the hall call button 8 according to the destination floor. Thereby, the elevator detects that the waiting customer 7 is on the floor where the button 8 is pressed. At this time or thereafter, voices are synthesized by the voice guidance control device 2 according to the situation, and the synthesized voices are notified from the speakers 3A, 3B, ...
The information notified here is, for example, the estimated arrival time of the elevator such as "It will arrive in about 30 seconds", and the reservation change information such as "Please use another elevator".
It is a first-arrival information guide such as "another elevator arrives first", and guides the waiting customer 7 in the elevator hall 1 by this notification.

Normally, in addition to the above-mentioned voice guidance, guide lights 5A and 5B (hereinafter referred to as hall lanterns) that inform the waiting customer 7 of the arrival of the elevator by lighting,
And hall chime 6 to notify arrival and the like by electronic sound
A and 6B are provided.

Next, the contents of the processing performed by the voice guidance control device 2 will be described. FIG. 5 is a block diagram showing the configuration of the voice guidance control device 2. First, which Holdor 4
From the upper speaker 3, data indicating what kind of sound is to be notified is sent from the control device in the elevator machine room. Data receiving unit 1 in the voice guidance control device 2
0 receives this data and sends it to the control CPU 11.
The control CPU 11 processes the sent data in accordance with the procedure stored in the storage unit 12, and controls the voice synthesis unit 13 to synthesize a predetermined voice. The voice synthesizing unit 13 reads out a necessary one of a plurality of voice data digitally stored in the voice data storage unit 14 at a predetermined sampling time interval by a predetermined method. The voice data storage unit 14 is often composed of a ROM having a high degree of integration. As a means for reproducing this voice data, a well-known voice waveform synthesis method (ADP) is usually used.
Data compression methods such as CM and ADM) are used. The storage amount required for reproducing the sound source in these sound source reproducing means is about 64 Kbit / sec. Since the capacity of the ROM generally obtained is about 2 Mbit at present, it is possible to store the voice for about 32 seconds.

Finally, the voice data storage unit 14
After converting the voice data read from the to analog to create a synthesized voice, send it to the speaker 3 to notify it, and the waiting customer 7
Let us know.

[0007]

As described above,
Compared with using only the hall lantern 5 and the hall chime 6 for guidance such as arrival of an elevator, if voice is used for guidance, a more convenient notification or guidance system can be provided. However, this speaker for voice guidance is attached to each elevator (car), and therefore a plurality of speakers are attached to one elevator hall, and at the same time, the same volume of guidance is given at the same volume. Has become. This is because it is not possible to know at which position in the elevator hall 1 the waiting passenger 7 is waiting, and it is necessary to notify the elevator hall 1 at a uniform volume. This function may be effective for a waiter because sufficient volume is obtained. However, originally, it is desirable that the elevator hall is in a quiet environment, and there is a problem that noise problems may occur when a human room such as an office is close to the elevator hall.

[0008] Further, there is a drawback in that it is not always possible to clearly know which elevator the guidance is about, because the same information is given from the speaker. For this reason, waiting passengers had to confirm hall lanterns and the like and hurry up before the arrival elevator.

Although it is possible to selectively make only the loudspeakers of the target elevators ring, if there is a wide elevator hall, for example, in case of group management of eight elevators, it is necessary to install it in every corner of the elevator hall. It is difficult to give notifications with sufficient and even volume throughout.

The present invention has been made to eliminate such inconvenience, and provides sufficient and clear information on the operation of the elevator to the waiting passengers and informs other users of the sound volume. It is an object of the present invention to provide a voice guidance device for an elevator hall that does not cause inconvenience because it is too large.

[0011]

A voice guidance device for an elevator hall according to the present invention comprises a detection means for detecting the operation status of the elevator, and an analysis means for analyzing information based on the operation status from the detection means. A data registering means for registering at least one digital sound source data, a converting means for taking out specific digital sound source data from the data registering means in accordance with an analysis result of the analyzing means, and converting the analog data into analog data; Volume registering means for registering the volume value, amplifying means for amplifying the analog data so as to realize the volume value registered in the volume registering means, and notifying the analog data to the waiting customer in the elevator hall. And a notification means.

[0012]

[Operation] When the operation status of the elevator is detected by the detection means, and when the waiting customer calls the elevator by the call button, how much time the elevator (car) will arrive at that floor, and which elevator will arrive the fastest Whether to do or not can be determined by the analysis means based on the information from the detection means. Then, the information is notified to the waiting customer by the following procedure. First, the digital voice data that is the source of the voice to be notified is taken out from the data registration means. Then, this digital audio data is converted into analog data of a predetermined format by a predetermined conversion operation. Subsequently, the volume value at the time of notifying the analog data is taken out from the volume registration means with reference to the analysis result of the analysis means, and amplified by the amplification means so as to realize the volume value. The amplified analog data is notified to the elevator hall by the notification means, so that the waiting customer can accurately obtain information necessary for using the elevator.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a voice guidance device for an elevator hall according to the present invention will be described below with reference to the drawings.

FIG. 1A is a block diagram showing an embodiment of a voice guidance device according to the present invention. This device is different from the conventional voice guidance device (see FIG. 5) in the environment data storage unit 16
And a voice amplifier 15 is additionally provided. Further, the elements common to the conventional ones are designated by the same reference numerals as those in FIG. 5 already described.

FIG. 2 is a flow chart showing the flow of processing performed by the voice guidance device. The embodiment of the present invention will be described below with reference to the flowchart of FIG. 2 and with reference to FIG.

First, the voice guidance control device 2 performs a data reception process (step S1). That is, the data indicating what kind of sound is to be notified from the speaker on which hold door is sent from the control device in the elevator machine room to the data receiving unit 10 in the voice guidance control unit 2. For example, the data is such that the waiting passenger of the elevator A is informed of the message "It will arrive in about 15 seconds". The data receiving unit 10 receives this data and transfers it to the control CPU 11. The control CPU 11 processes the sent data according to the procedure stored in the storage unit 12.

Next, the control CPU 11 checks whether or not a message is currently notified from the speaker, and if it is in the middle of notification, waits until the notification is completed without performing the next processing (step S2). ). Then, after the notification of the message from the speaker is completed, the control CPU 11 sends the data necessary for voice synthesis to the voice synthesizer 13 and controls it. The voice synthesizing unit 13 reads out necessary data from a plurality of voice data digitally stored in the voice data storage unit 14 at a predetermined sampling time interval by a predetermined method. Then, the voice data is converted to analog to create a synthesized voice, and then sent to the voice amplifier 15.
Here, the audio amplification unit 15 is called a progableable gain controller (PGC), and its output, that is, the speaker volume can be adjusted by a command from the control CPU 11. The steps until the synthetic speech is passed to the speech amplification section 15 are called speech synthesis processing (step S3).

Further, the control CPU 11 controls the voice synthesizing unit 13 and, at the same time, reads the contents of the voice control table and the surrounding data table regarding the target elevator from the environment data storage unit 16. This environmental data storage unit 16
Is composed of an EEROM (electrically erasable ROM) or the like. Therefore, even if the elevator partially fails, the volume can be easily adjusted. The volume control table is configured as shown in FIG. In this table, the volume notified by all speakers for each target elevator is registered. Assuming that the volume amplification unit 15 realizes the volume control with 4 bits, the registered value of the volume control table is represented by a 4-digit number. For example, when the registered value is "1111", the notification sound volume is 0 dB, when "1110" is -1 dB, when "1101" is -2 dB, and when it is "0000", output volume is cut off. Therefore, FIG. 1 (b)
When the target elevator is A, the volume notified by the speakers 3A, 3B and 3C is "1111",
“1110” and “1110”. That is, 0 dB,
It shows that it is -1 dB and -1 dB.

Next, consider the case where the elevator halls are arranged in a plane as shown in FIG. Now, a total of 6 elevators A to F are equipped with speakers 3A to 3F, respectively.
Shall be attached. Now, suppose that elevator B arrives the fastest, and wants to inform waiter 7 of that. In that case, the loudspeaker 3B of the elevator B notifies the synthesized voice of the content such as "This elevator arrives fastest" at a louder volume than the other loudspeakers, and the louder than the other loudspeakers 3A, 3C to 3F. Notify by volume. As a result, the waiting customer 7 knows that the notification this time is for the elevator B and can know the content of the notification accurately, and can gather in front of the elevator B without delay. Therefore, it becomes possible to smoothly use the elevator as a group management.

Further, in the surrounding data table of the environment data storage unit 16, data indicating the level of background noise of the elevator hall or the like is registered. This environmental data storage unit 1
Control CP that has read the data related to the alarm volume from 6
U11 controls the audio amplification unit 15 based on the data,
Make sure the volume is set to the specified level. At this time, the control CPU
11 can control a plurality of audio amplification units 15 separately, and it is possible to make a notification with the volume registered in the environment data storage unit 16, which is different for each speaker. Speaker volume control (step S
4).

In this embodiment, the case where one speaker is installed on the hold door has been described, but it is not always necessary to install one speaker for each elevator. For example, for two elevators. It is also possible to install one speaker. Also in this case, it is possible to easily cope with this by changing the table of the environment data storage unit 16 accordingly.

As shown in FIG. 3, in the case of an elevator installation of a face-to-face arrangement, the speaker is arranged only in one of the elevators, and the speaker arrangement is omitted in the elevators in the other rows. You can also

Although an EEROM is considered here as an example of the environment data storage unit 16, a battery backup type RAM can also achieve the same function.

Furthermore, a microphone is installed on the wall surface of the elevator hall, and noise generated by waiting passengers and other causes is measured by the microphone, and the ambient data table in the environmental data storage unit 16 is automatically set in accordance with the noise. It can also be updated.

[0025]

As described above, according to the present invention,
The loudspeaker installed near the door of the target elevator can give a loud sound, and the loudspeakers of other elevators can give a lower sound volume to inform the information about the operation status of the elevator. At this time, noises in the elevator hall can be easily taken into consideration only by rewriting the table. Therefore, even if the background noise level of the elevator hall is high, the content of the notification is not overwhelmed by the background noise, and the waiting passengers can be reliably guided. In addition, it is possible to avoid a situation in which the volume is notified at an unnecessarily high volume, and it is possible to avoid annoying the people around.
