An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. The broadcast adjustment device according to this embodiment is a device that adjusts broadcast audio in a car. An elevator equipped with a broadcast control device includes, for example, a car 1 and a control panel 2 for controlling operation of the car 1, as shown in FIG. The car 1 is a car that ascends and descends a hoistway that extends vertically across a plurality of floors in a building.

The control panel 2 can be used to call a hall (for example, when a user presses a hall call button at a hall on one of the floors of the building) or call a car (for example, when a user who has boarded the car 1 Pressing the destination floor button to register the destination floor), the car 1 is controlled to run or stop. In the present embodiment, the control panel 2 includes a call information storage unit 20 that stores information about hall calls and car calls, an alarm information storage unit 21 that stores information about alarms to be issued when an elevator malfunction occurs, etc. Prepare. Further, the control panel 2 outputs a warning command to the broadcast adjustment device 5 (specifically, the announcement control section 70 described later) when the need for warning arises. The notification command includes information on the type of notification (for example, earthquake, fire, etc.).

When a hall call is received, the call information storage unit 20 stores hall call floor information (information about the floor where the hall call is received). Further, the call information storage unit 20 stores destination floor information (information about the destination floor registered by the car call) when a car call is received.

The alarm information storage unit 21 stores alarm information, which is information relating to the alarm, when it is necessary to issue an alarm. For example, the alarm information storage unit 21 stores "earthquake occurrence information" as the alarm information from the time when the monitoring center that monitors the elevator reports that an earthquake has occurred until the time when the alarm is issued.

The car 1 includes an announcement device 3 for making voice announcements in the car 1, a speaker 6 for broadcasting voice announcements in the car 1, etc., in addition to a car main body in which a user gets on.

The announcement device 3 includes an audio data storage unit 4 for storing audio data, which is data for audio announcements, and a broadcast adjustment device 5 for controlling the content, volume, etc. of the audio announcements. The announcement device 3 is, for example, a CPU, a non-volatile storage element such as a ROM or an EEPROM for pre-storing various programs to be executed by the CPU and data necessary for the execution, or a so-called working memory of the CPU. It is composed of a board, a microcomputer, etc., which is equipped with a volatile memory element such as a RAM and its peripheral circuits.

The voice data storage unit 4 stores, as voice data, voice announcements relating to alarms (for example, voice announcements such as "An earthquake has occurred"), voice announcements notifying the arrival floor of car 1, and opening and closing of car doors. It stores voice announcements and the like.

The broadcast adjustment device 5 is a device that automatically adjusts the broadcast sound within the car 1 according to the lifting distance of the car 1 and the speed of the car 1 . The broadcast adjustment device 5 also includes a sound adjustment unit 7 that changes the broadcast sound in the car 1 according to at least one of the elevator distance of the car 1 and the speed of the car 1 . Further, the broadcast adjustment device 5 includes a volume data determination unit 8 that determines information regarding the volume of the broadcast in the car 1 of the voice announcement. The lifting distance of the car 1 is the lifting distance per one run of the car 1 (for example, after the car door opens, the car 1 ascends or descends, and the car door opens). be.

The volume data determination unit 8 includes a volume determination unit 80 that creates information about the volume of the broadcast in the car 1, a lift distance determination unit 81 that determines the lift distance of the car 1, and a lift distance of the car 1 corresponding to the lift distance of the car 1. A rated speed storage unit 82 that stores speeds and a speed storage unit 83 that determines the speed of the car 1 are provided.

The ascending/descending distance determination unit 81 stores, for example, a plurality of ascending/descending distances when the car 1 in which the broadcast adjustment device 5 is installed travels between predetermined floors. Specifically, the ascending/descending distance determination unit 81 stores the ascending/descending distance of the car 1 corresponding to each different floor. More specifically, the ascending/descending distance determining unit 81 determines that the ascending/descending distance of the car 1 between the first floor and the twentieth floor is 80 m, and that the ascending/descending distance of the car 1 between the first floor and the thirtieth floor is 120 m. It stores information such as When the car 1 moves up and down over a distance of approximately 40 m to 50 m or more, an air pressure change of 5 hPa or more occurs as the car 1 moves up and down, which may cause ear clogging.

The rated speed storage unit 82 stores, for example, values determined for each elevator. Specifically, the rated speed storage unit 82 stores a rated speed of 300 m/min.

The speed storage unit 83 stores, for example, a plurality of speeds of the car 1 (specifically, the maximum speed of the car 1) for each ascending/descending distance. Specifically, the speed storage unit 83 stores a maximum speed of 100 m/min for the elevator car 1 of 20 m.

The volume determination unit 80 determines volume data information according to at least one of the ascending/descending distance of the car 1 and the speed of the car 1 . Further, the volume determination unit 80 determines the volume data information so that the volume of the broadcast sound in the car 1 increases as the car 1 moves up and down and as the car 1 speed increases. Specifically, the volume determination unit 80 determines the volume data information so as to increase the volume of the broadcast sound in the car 1 when at least one of the ascending/descending distance of the car 1 and the speed of the car 1 is equal to or greater than a predetermined value.

In this embodiment, the volume determination unit 80 determines volume data information according to both the ascending/descending distance of the car 1 and the speed of the car 1 . Note that the volume determination unit 80 may determine the volume data information only according to the ascending/descending distance of the car 1 or may determine the volume data information only according to the speed of the car 1 .

In the present embodiment, the volume determining unit 80 determines the volume of the broadcast sound in the car 1 regardless of whether the car 1 is ascending or descending if the elevator distance and the speed of the car 1 are the same. keep the volume the same. Note that the sound volume determination unit 80 determines that when the car 1 is lowered and the speed of the car 1 is the same, the broadcast sound inside the car 1 is louder than when the car 1 is raised. volume can be increased. As a result, the volume of the broadcast sound in the car 1 can be made appropriate when the car 1 is lowered, which tends to cause the user's ears to become clogged.

The volume determination unit 80 stores a plurality of volume data information corresponding to the ascending/descending distance of the car 1 and the speed of the car 1 . Specifically, the volume determination unit 80 stores volume data information when adjustment of the volume of the broadcast sound is required. More specifically, the volume determination unit 80 stores the volume data information at a ratio (for example, 150%) when the normal volume is 100%.

For example, the sound volume data determining unit 8 determines the ascending/descending distance determined by the ascending/descending distance determining unit 81, the rated speed stored in the rated speed storage unit 82, and the speed of the car 1 stored in the speed storage unit 83. to determine the corresponding volume data information. Specifically, when the rated speed stored in the rated speed storage unit 82 is 300 m/min, the volume data information 150% is determined as Further, when the speed of car 1 corresponding to the lifting distance determined by lifting distance determining unit 81 among the speeds of car 1 stored in speed storage unit 83 satisfies a predetermined value or more, sound volume determining unit 80 generates sound volume data. Determine 150% for information.

When the sound volume data determination unit 8 determines the sound volume data information according to the speed of the car 1, instead of the speed of the car 1 stored in the speed storage unit 83, it is calculated based on the operating conditions of the car 1. The volume data information may be determined according to the speed of the cage 1 . The operating conditions of the car 1 include, for example, the lifting distance of the car 1, whether the car 1 is ascending or descending, the load of the user of the car 1 and the cargo, and the like. In this case, the volume data determination section 8 does not need to include the speed storage section 83 .

The sound adjustment unit 7 changes the sound inside the car 1 according to both the ascending/descending distance of the car 1 and the speed of the car 1 . Further, the sound adjustment unit 7 changes the volume of the broadcast sound inside the car 1 according to the lifting distance and speed of the car 1 . Specifically, the sound adjustment unit 7 includes an announcement control unit 70 and a volume adjustment unit 71 that adjusts the volume of the voice announcement from the speaker 6 .

The announcement control unit 70 determines whether voice announcement to the user is necessary. For example, the announcement control unit 70 determines whether or not a voice announcement is necessary according to the presence or absence of alarm information stored in the alarm information storage unit 21. When the information is stored, it determines that a voice announcement is required. It should be noted that even if the alarm information is stored in the alarm information storage unit 21 or not, the announcement control unit 70 makes a normal voice announcement unrelated to the alarm (for example, , announcements when opening and closing doors, etc.).

Also, the announcement control unit 70 determines whether or not it is necessary to adjust the volume of the voice announcement. For example, the announcement control unit 70 determines whether it is necessary to adjust the volume of the voice announcement according to at least one of the ascending/descending distance of the car 1 and the speed of the car 1 . Specifically, the announcement control unit 70 stores a predetermined value as a threshold for adjusting the volume of the voice announcement with respect to the ascending/descending distance of the car 1 and the speed of the car 1. When the speed of car 1 exceeds a threshold (predetermined value), it is determined that volume adjustment is necessary.

Furthermore, the announcement control unit 70 controls the use of the car 1 when the ascending/descending distance of the car 1 is short or when the speed of the car 1 is low (for example, when the ascending/descending distance of the car 1 or the speed of the car 1 is less than a predetermined value). It is judged that the adjustment of the volume is not necessary because it is difficult for people to experience ear clogging. Note that the announcement control unit 70 may always adjust the volume of the voice announcement according to at least one of the ascending/descending distance of the car 1 and the speed of the car 1 .

In the broadcast adjustment device 5 of the present embodiment, the announcement control unit 70 determines that volume adjustment is necessary when at least one of the ascending/descending distance of the car 1 and the speed of the car 1 exceeds a predetermined value. In other words, the announcement control unit 70 operates when only the ascending/descending distance of the car 1 exceeds a predetermined value (for example, 50 m) and the speed of the car 1 is less than a predetermined value (for example, any value of 100 m/min or less). Even if there is, it is determined that the volume needs to be adjusted. Similarly, the announcement control unit 70 outputs when the lift distance of the car 1 is less than a predetermined value (for example, 50 m) and the speed of the car 1 exceeds a predetermined value (for example, any value of 100 m/min or more). Even so, it is determined that the volume needs to be adjusted.

The announcement control unit 70 acquires voice data information from the voice data storage unit 4 when performing voice announcements in the car 1 . For example, when receiving an alarm command, the announcement control unit 70 acquires voice data information corresponding to the received alarm command from the voice data storage unit 4 .

Further, when the voice announcement in the car 1 is executed and the volume adjustment is unnecessary, the announcement control unit 70 outputs the voice data information acquired from the voice data storage unit 4 to the volume adjustment unit 71 and outputs the voice data information to the speaker. 6 to output a voice announcement at a normal volume. On the other hand, the announcement control unit 70 sends the volume data determined by the volume determination unit 80 to the volume adjustment unit 71 in addition to the voice data information when the voice announcement in the car 1 needs to be adjusted. Then, the voice announcement is output from the speaker 6 at the volume based on the volume data information.

The volume adjustment section 71 generates a voice announcement based on the voice data information from the announcement control section 70 and outputs it to the speaker 6 . Further, the volume adjustment unit 71 adjusts the volume of the voice announcement from the speaker 6 when the volume data information is output from the announcement control unit 70, and adjusts the volume of the voice announcement from the speaker 6 when the volume data information is not output from the announcement control unit 70. Keep the volume of 6 at the normal volume (do not adjust the volume).

Processing related to adjustment of the broadcast sound in the car 1 by the broadcast adjusting device 5 will be specifically described with reference to FIG. In the following description, the process for adjusting the volume of the voice announcement regarding the alarm in car 1 will be explained, but the volume of other voice announcements (such as the voice announcement that informs the arrival floor of car 1) will be adjusted. may

When the car 1 arrives at the landing and the car doors are opened and then closed, the lift distance determination unit 81 determines the lift distance of the car 1 from the information in the call information storage unit 20 of the control panel 2 ( step S01). Specifically, the ascending/descending distance determination unit 81 determines the ascending/descending distance of the car 1 corresponding to the hall call floor information and the destination floor information stored in the call information storage unit 20 . More specifically, the ascending/descending distance determination unit 81 determines the ascending/descending distance corresponding to the hall call floor information and the destination floor information stored in the call information storage unit 20 from the predetermined ascending/descending distance between floors stored in advance. By extracting, the ascending/descending distance of the car 1 is determined. For example, when a car call on the 20th floor is registered in a car that has stopped on the first floor, the ascending/descending distance determination unit 81 extracts the ascending/descending distance "80 m" corresponding to the destination floor information, and "80m" is determined as the distance.

Next, the announcement control unit 70 determines whether or not a voice announcement is necessary for the users in the car 1 (step S02). Specifically, the announcement control unit 70 determines that a voice announcement is necessary when the alarm information is stored in the alarm information storage unit 21, and the alarm information is not stored in the alarm information storage unit 21. Occasionally decides that voice announcements are unnecessary.

When the announcement control unit 70 determines that a voice announcement is necessary for the user (step S02: Yes), it determines whether or not it is necessary to adjust the volume of the voice announcement (step S03). Specifically, the announcement control unit 70 determines whether or not it is necessary to adjust the volume of the voice announcement based on whether at least one of the lift distance of the car 1 and the speed of the car 1 exceeds a predetermined value. More specifically, when the lifting distance determined by the lifting distance determination unit 81 is equal to or greater than a predetermined value (for example, 50 m), the announcement control unit 70 determines that the volume of the voice announcement needs to be adjusted. In addition, the announcement control unit 70 sets the speed corresponding to the lifting distance determined by the lifting distance determination unit 81 to a predetermined value (for example, 100 m/min or more) among the speeds of the car 1 stored in the speed storage unit 83 . value) or more, it is determined that the volume of the voice announcement needs to be adjusted.

Furthermore, when the announcement control unit 70 determines that it is necessary to adjust the volume of the voice announcement (step S03: Yes), it receives an alarm command from the control panel 2 (step S04), and the volume data determination unit 8 (step S05).

The volume data determination unit 8 determines volume data information upon receiving the volume setting command (step S06). Specifically, the volume data determination unit 8 determines volume data information according to both the ascending/descending distance of the car 1 and the speed of the car 1 . More specifically, the volume determination unit 80 determines the elevation distance determined by the elevation distance determination unit 81 from among the elevation distance determined by the elevation distance determination unit 81 and the speed of the car 1 stored in the speed storage unit 83. volume data information is determined according to the speed corresponding to . For example, when the rated speed stored in the rated speed storage unit 82 is 300 m/min, the volume determination unit 80 sets the volume data information as " 150%”.

When the announcement control unit 70 receives the volume data information from the volume data determination unit 8 (step S07) and acquires the audio data information from the audio data storage unit 4 (step S08), the announcement control unit 70 adjusts the volume of the audio data information and the volume data information. 71 (step S09). Further, the volume adjustment unit 71 generates a voice announcement from the voice data information, outputs the voice announcement from the speaker 6 at a volume based on the volume data information (step S10), and the process ends.

When the announcement control unit 70 determines that the voice announcement is not necessary for the user (step S02: No), the process returns to the "decide the lifting distance" process of step S01. Further, when the announcement control unit 70 determines that the volume of the voice announcement does not need to be adjusted (step S03: No), the process proceeds to the "receipt of volume data information" process of step S08, and the normal volume is played. A voice announcement is made (steps S09 and S10), and the process ends.

According to the broadcast adjustment device 5 described above, the sound adjustment unit 7 changes the voice guidance and music played in the car according to the running state of the car 1 (at least one of the car's ascending/descending distance and the car's speed). To appropriately convey voice guidance and music to a user even if the user has ear clogging.

Further, according to the broadcast adjustment device 5 of the above-described embodiment, the sound adjustment section 7 can adjust the volume of the voice guidance in the car according to the running state of the car 1 to an appropriate one for the user.

It should be noted that the broadcast adjustment apparatus of the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, some of the configurations of certain embodiments can be deleted.

In the above-described embodiment, the sound adjustment unit 7 adjusts the broadcast sound in the car 1 according to both the lift distance of the car 1 and the speed of the car 1, but only according to the lift distance of the car 1, The broadcast sound inside the car 1 may be adjusted, or the broadcast sound inside the car 1 may be adjusted according to only the speed of the car 1 . The sound adjustment unit 7 may adjust broadcast sounds other than voice announcements, such as BGM played in the car 1 and effect sounds played in the car 1 when the door is opened and closed.

Further, in the above embodiment, the sound adjustment unit 7 adjusts the volume of the broadcast sound in the car 1, but in addition to or instead of adjusting the volume of the broadcast sound , the frequency of the broadcast sound in the car 1, the speed of the voice guidance, the number of times the voice guidance is broadcast, and at least one of the contents of the broadcast may be changed.

When the sound adjustment unit 7 adjusts the frequency of the broadcast sound in the car 1, for example, when the lifting distance of the car 1 or the speed of the car 1 is large, the frequency of the broadcast sound in the car 1 is adjusted to cause ear clogging. It may be adjusted to a frequency that is easy for the user to hear. Specifically, the sound adjustment unit 7 may use the male voice announcement and the female voice announcement separately when the elevator distance of the car 1 or the speed of the car 1 is large. Further, when the sound adjustment unit 7 adjusts the speed of the voice guidance, for example, when the lift distance of the car 1 or the speed of the car 1 is large, the speed of the broadcast sound of the voice guidance may be slowed down. When the sound adjustment unit 7 adjusts the number of times the voice guidance is broadcast, for example, when the ascending/descending distance of the car 1 or the speed of the car 1 is large, the number of times the voice guidance is broadcast may be increased. Furthermore, when the sound adjustment unit 7 changes the content of the broadcast in the car 1, for example, in order to call attention to the user who has clogged ears, a voice announcement different from the normal voice announcement (for example, a strong voice) announcement) or BGM different from usual may be broadcast. According to such a configuration, the volume of the voice guidance and music in the car 1, the frequency of the broadcast sound, the speed of the voice guidance, the number of broadcasts of the voice guidance, the content of the broadcast (voice guidance and music content itself) can be made appropriate for the user, and information can be easily transmitted to the user.

Furthermore, if the broadcast period of the broadcast sound (for example, voice announcement or BGM) in the car 1 is longer than a certain period of time, the sound adjustment unit 7 adjusts the broadcast sound according to the traveling state of the car 1 during the broadcast sound. (eg, volume) may be changed. For example, when the car 1 moves up and down a long distance, it is conceivable to set the volume of the broadcast sound to a normal volume at the start of travel, and increase the volume of the broadcast sound during travel or at the end of travel. In this case also, the voice guidance and music in the car 1 can be made suitable for the user according to the running state of the car 1.

Further, when at least one of the ascending/descending distance of the car 1 and the speed of the car 1 is equal to or greater than a predetermined value, the sound adjustment unit 7 adjusts at least part of the broadcast in the car 1 (all or part of the broadcast in the car 1). You may set the predetermined period which stops. This predetermined time is, for example, from when at least one of the ascending/descending distance of the car 1 and the speed of the car 1 becomes equal to or greater than a predetermined value to when the car 1 stops (specifically, when the car 1 moves before the car 1 stops). (until the start of the voice announcement announcing the end of the operation). When part of the broadcast in car 1 is suspended, urgent broadcasts (e.g., broadcasts related to earthquakes, fires, etc.) in car 1 will be broadcast, while non-urgent broadcasts (e.g., BGM, etc.) may be stopped. According to such a configuration, when the user is likely to have ear clogging, it is possible to stop the broadcasting of voice guidance and music, thereby preventing the user from being stressed by being unable to hear the broadcast accurately. . In this case, a display or the like provided in the car 1 may inform the content of the voice announcement that was originally supposed to be broadcast.

In the above embodiment, the sound adjustment unit 7 (announcement control unit 70) determines whether or not the volume of the voice announcement needs to be adjusted (step S03), but this determination may be omitted. . Specifically, when an announcement to the user is required (step S02: Yes), the process from step S04 onwards may be performed without determining whether or not the volume of the voice announcement needs to be adjusted. In this case, in addition to the volume data information when it is necessary to adjust the volume of the broadcast sound, the volume determination unit 80 determines volume data information when the volume of the broadcast sound does not need to be adjusted (normal volume data information). possible to remember. In addition, the volume data determination unit 8 stores 100% as normal volume data information, the elevation distance determined by the elevation distance determination unit 81 is less than a predetermined value (for example, 50 m), and the rated speed storage unit When the speed of car 1 stored in 83 is less than a predetermined value (for example, any value of 100 m/min or more), 100% (that is, no volume adjustment) is determined as volume data information. do it.

An elevator equipped with the broadcast adjusting device 5 may be equipped with an air pressure adjusting device capable of adjusting the air pressure inside the car 1 . In this case, it is conceivable that the sound adjustment unit 7 changes the broadcast sound in the car 1 in conjunction with the atmospheric pressure adjustment device. In this case, the sound adjustment unit 7 changes the broadcast sound in the car 1 according to the air pressure of the car 1 in addition to the running state of the car 1 .

Specifically, when the air pressure adjustment device adjusts the air pressure in the car 1 based on the air pressure command value output from the control panel 2, the control panel 2 also outputs the air pressure command value to the sound adjustment unit 7, The adjustment unit 7 may change the broadcast sound based on the atmospheric pressure command value. More specifically, the volume data determining section 8 may determine the volume data according to the atmospheric pressure command value. According to such a configuration, the voice guidance and music flowing in the car 1 change according to the air pressure in the car 1, so that even if the user has ear congestion, the voice guidance and music can be easily heard.

Further, the sound adjustment unit 7 may change the broadcast sound inside the car 1 according to the noise around the car 1 and inside the car 1 in addition to the traveling state of the car 1 . In this case, it is conceivable that the car 1 is provided with a noise detection device. According to this configuration, the voice guidance and music played in the car 1 change according to the noise around and in the car 1, so that even if the user has ear congestion, the voice guidance and music can be easily heard. become a thing.

Note that the sound adjustment unit 7 may adjust the broadcast sound in the car 1 in accordance with the traveling state of the car 1 only when the car 1 is manned. In this case, the sound adjustment unit 7 is based on, for example, a human sensor provided in the car 1, the operation of the destination floor button and the open/close button in the car 1, and the presence or absence of a user in the car 1 due to the load of the car 1. , it may be determined whether or not the broadcast sound in the car 1 needs to be adjusted according to the running state of the car 1 .

In addition to the running state of the car 1, the sound adjustment unit 7 may adjust the broadcast sound so that the broadcast sound in the car 1 can be easily heard when there are many users in the car 1. .

Furthermore, the sound adjustment unit 7 may adjust the broadcast sound inside the car 1 according to environmental parameters such as temperature and humidity inside the car 1 in addition to the running state of the car 1 .
