Japanese Patent Laid-Open No. 06-135649

  By the way, the intercom slave is supplied with power from a battery. In such a battery, the charging current is reduced in order to avoid overcharging. Therefore, if the BGM continues to flow for a long time, the amount of power stored in the battery decreases, and the intercom cannot be used during a power failure.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain a BGM device in an elevator car that normally allows BGM to flow while ensuring the original function as an interphone in an emergency. .

An elevator car BGM device according to the present invention is an elevator car BGM device that sends BGM from an interphone slave unit installed in an elevator car, an interphone controller that controls the interphone, and a music that temporarily stores music data A storage unit; and a battery that supplies power to the interphone slave unit. The interphone controller includes a reference time point specifying unit that specifies a reference time point, and a charge amount of the battery at the reference time point. The charge amount calculating means for calculating the charge amount of the battery, the elevator operation data is acquired, and when the elevator operation data is found from the acquired elevator operation data, the speaker of the interphone slave unit is driven, When play music at a predetermined volume corresponding to the charge amount calculated by the charge amount calculating means Moni, when the charge amount calculated by the charge amount calculating means, and the following lower limit charge amount that has been preset as the charge amount does not hinder to make an emergency communication using the interphone handset Has a music ringing means for preventing the music from flowing .

  The elevator car BGM device according to the present invention adjusts the volume of the BGM in accordance with the amount of charge of the battery, so that the battery stores electric power necessary for making an emergency call, so the battery is discharged. It is possible to prevent emergency calls from being made.

It is a block diagram which shows the structure of the BGM apparatus in an elevator car which concerns on embodiment of this invention. It is a functional block diagram of the intercom control part which concerns on embodiment of this invention. It is a figure which shows the change of the charge amount from a reference | standard time. It is a figure which shows the change of charge amount when a commercial power source carries out a power failure.

Hereinafter, preferred embodiments of an elevator car BGM device of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of an elevator car BGM device according to an embodiment of the present invention. FIG. 2 is a functional block diagram of the intercom control unit according to the embodiment of the present invention.
An elevator car BGM device 1 according to an embodiment of the present invention includes an interphone slave unit 3 arranged in an elevator car 2, a monitoring device 4 for controlling the interphone slave unit 3, a monitoring device 4 and a communication network 5. And a music server 7 placed in the remote monitoring center 6.
The intercom handset 3 is disposed in the in-car operation panel 8 and includes a call button 11, a microphone 12, and a speaker 13 for calling an interphone base unit 9 provided in the remote monitoring center 6.

The monitoring device 4 includes an interphone control unit 15 that controls the interphone, a music storage unit 16 that temporarily stores music data, the interphone slave unit 3, and a battery 17 that supplies power to the monitoring device 4.
The intercom control unit 15 includes a computer having a CPU, a ROM, a RAM, and an interface circuit. The intercom control unit 15 detects the time zone when the elevator operation is almost stopped, for example, at midnight, for example, the reference time point specifying means 21 for specifying the reference time point, and the charge amount of the battery 17 at the reference time point The charge amount calculation means 22 for calculating the charge amount of the battery 17 and the elevator operation data from the elevator control unit 23 are obtained, and when it is understood from the acquired elevator operation data that the elevator is in operation, the music server 7 The music piece storage unit 24 temporarily stores the obtained music piece data in the music piece storage unit 16 and drives the speaker 13 of the intercom handset 3 to play the music piece at a predetermined volume.

  The charge amount calculation means 22 sets the charge amount as a predetermined full charge amount at the reference time, and subtracts the discharge amount corresponding to the volume from the full charge amount when the speaker 13 is ringing, and a commercial power source (not shown) When alive, the charge amount TAh per unit time is added, and when the commercial power supply is out of power, the discharge amount SAh due to self-discharge is subtracted. Note that four volumes are preset, and zero level, low level, medium level, and normal level are set in ascending order. Four discharge amounts are determined in advance corresponding to the four sound volume levels. That is, 0Ah, B1Ah, B2Ah, and B3Ah.

The music ringing means 24 selects the volume based on the charge amount calculated by the charge amount calculation means 22. For example, a normal level is set when the charge amount exceeds 80% of the full charge amount, a medium level when the charge amount exceeds 80% or less, 60%, a low level when the charge amount exceeds 60% or less, and a zero level when the charge amount is 40% or less.
The music ringing means 24 acquires elevator operation data from the elevator control unit 23 and determines whether or not to play music from the speaker 13 based on the acquired operation data. That is, when the elevator is in operation, the music stored in the music storage unit 16 is played as BGM. The volume at that time is selected according to the amount of charge as described above. On the other hand, when the elevator is stopped, BGM is not flowed.

By the way, when the call button 11 of the intercom handset 3 is pressed to make an emergency contact, the elevator is in operation and the BGM is being played, but the BGM is stopped and the line is connected to the interphone parent. Connect to machine 9. Since the call button 11 is pressed, a call signal is transmitted to the intercom base unit 9.
Since the intercom master unit 9 is ringed by the call signal, the supervisor speaks with the passengers in the elevator car 2.

Next, how the charge amount changes from the reference time point will be described. FIG. 3 is a diagram illustrating a change in the charge amount from the reference time point.
For example, if a passenger uses an elevator by 1 am at 5 am, the charging amount at that time is FAh as a reference time point. Since the amount of charge exceeds 80%, BGM is played at a normal level. Then, the amount of charge is reduced by (B3-T) Ah × (time in which BGM is passed) h. Since the elevator is operated from about 8 o'clock to about 20 o'clock, the amount of charge gradually decreases, and the volume of the BGM is changed each time the amount of charge falls within a predetermined range. After 20:00, the time zone in which the BGM is played is short, so the amount of charge increases and at dawn, the battery fully recovers.

FIG. 4 is a diagram illustrating a change in charge amount when a commercial power supply fails.
In the above example, since the commercial power source is alive, the battery is always charged. However, when the commercial power source fails, the battery cannot be charged. Therefore, the BGM is not supplied and the charge amount is reduced by the self-discharge SAh. That is, since the commercial power supply has been cut off from 14:00 to 20:00, there is no charge when BGM is flowed, so the amount of charge suddenly decreases and reaches 40% or less of the full charge. Then, since BGM is prevented from flowing, the amount of charge decreases by the amount of self-discharge.
However, since the amount of charge is maintained at less than 40%, there is no obstacle even if an emergency call is made using an intercom.

The elevator car BGM device 1 according to the present invention adjusts the volume of the BGM in accordance with the amount of charge of the battery 17, so that the battery 17 stores electric power necessary for making an emergency call. It is possible to prevent emergency calls from being made due to discharge.
In addition, since the BGM is played using the intercom provided for emergency contact, it is not necessary to install a separate BGM broadcasting facility, and the BGM service can be provided at a low cost.

In the above-described embodiment, it is determined that the battery 17 is in a fully charged state when the elevator is stopped for a predetermined time. However, the terminal voltage of the battery 17 is measured and the fully charged state is determined. It may be detected.
Further, although the volume is varied by distinguishing the amount of charge into four areas, the number of areas is not limited to this.
