Abstract

PURPOSE:To attain sure and quick refuge guidance in case of emergency by providing a display means receiving presence or absence information and displaying visually the presence or absence state for each extension to a private emergency information equipment. CONSTITUTION:In case of a fire occurred, when an information start circuit 32 starts an informing circuit 31, extension telephone sets 21-2n are connected sequentially switchingly to the talking circuit 31 and a call signal is sent from a call signal source 310 to each extension telephone set. Simultaneously, a display control circuit 34 receivers call information of each extension from the informing circuit 31 and fetches presence information of each guest room via a reception circuit 33 from an interface circuit 11 of an exchange 1 and applies call display and presence display for each extension line onto display lamps A, B in an extension state display device 35. Thus, it is not required for a sender of emergency notice to pay attenuation to guest rooms where no guest exists and the emergency informing state is monitored only for the guest rooms where guests exist.

Description

DETAILED DESCRIPTION OF THE INVENTION ('Industrial Field of Application) The present invention relates to an extension status display system, and more particularly to an extension status display system in an emergency internal notification system.

[Conventional technology]

Conventionally, this type of extension status display system has been used to display a message on the emergency premises alarm that when an emergency call is made by activation from the emergency premises alarm, the extension subscriber responds by turning off. It was designed to be visible.

[Problem that the invention seeks to solve]

In the conventional extension status display method described above, it is visually displayed that the extension subscriber has responded to an emergency call. It will continue to be unresponsive forever.

Generally, emergency telephone systems are installed in lodging facilities such as hotels and inns, but there are extension lines that are not occupied by guests. In such cases, the conventional method has the drawback that when a call is made from the emergency on-premises telephone, it is difficult to determine whether the guest room whose extension does not respond is vacant or whether the guest is unable to respond for some reason. .

[Means for Solving the Problems 1] The extension status display system of the present invention requires no human effort to input information on the presence/absence of extension subscribers in an emergency telephone system connected between a private telephone exchange and an extension telephone. The means and this existence
Embodiment Next, the present invention will be described with reference to the drawings.

FIG. 1 shows a professional example of an embodiment of the extension status display method of the present invention.
This is a diagram.

The extension circuit of the horizontal telephone exchange fil is connected to the notification circuit 31 of the emergency premises notification device 3, and then connected to the extension telephone 21. -2n. The emergency on-premise notification device 3 includes a notification circuit 318, a notification activation circuit 32. Receiving circuit 33 for presence/absence information. It is composed of an extension status display control circuit 3.1 and an extension status display 35. 1 Mana, private branch telephone exchange 1 interface circuit (1:'J, lower INF>11
is connected to the receiving circuit 33, and furthermore, the reporting circuit 3
1 is a calling signal source 310 and an announcement device 31 connected to each extension telephone via an L+3 switching relay contact, respectively;
1, and the extension status indicator 35 is provided for each extension telephone fi21.
Equipped with indicator lamps A and B corresponding to ~2n.

Next, the operation of this embodiment will be explained.

It is assumed that a guest is currently in the guest room with the extension telephone 1M21, and the guest room with the extension telephone 2n is vacant. The private branch telephone exchange 1 has a telephone billing function (not shown), and its information, which is information on entering and leaving the guest room, is sent to the receiving circuit 33 via INFII.

Here, when the notification activation circuit 32 activates the notification circuit 31 due to the occurrence of a fire, for example, the extension telephones 21° to 2n are sequentially switched and connected to the notification circuit 31, and a calling signal is sent from the calling signal source 310 to each extension telephone. . At the same time, the display control circuit 34 receives ringing information for each extension from the notification circuit 31, and also receives entry/exit information for each guest room from INFII via the reception circuit 33, and displays the extension status display 3.
Display lamps A and B in 5 indicate whether each extension is ringing and whether or not it is present. Therefore, in this embodiment, the display lamp A corresponding to the extension telephone 21 lights up to indicate that the user is in the room, and the display lamp B blinks to indicate that the call is in progress, and the display lamp A corresponding to the extension telephone 2n does not light up. The display lamp B blinks to indicate that the caller is not present and that the caller is currently calling.

Here, when the guest using the extension telephone 21 that is making a call for a report responds by going off-off, the report circuit 31 detects this, switches the connection from the call signal source 310 to the announcement device 311, and issues an evacuation announcement. At the same time as sending out the extension response information, the display control circuit 34 sends the extension response information to the display control circuit 34.Based on this information, the display lamp B corresponding to the extension telephone v121 is switched on to indicate that the guest has responded.

Note that the method of inputting the presence/absence information of a guest room is not limited to the method of this embodiment, but may also be a method of receiving information from a guest room management computer of a hotel, inn, etc., or a method of inputting information on the presence/absence of a guest room in advance to an emergency alarm system. Any method such as providing a separate capotan may be used.

1. Invention 21) River) As described in the above explanations 1 to 1, the present invention provides a call state of an extension telephone as an extension of an emergency on-premises telephone, and a 1-indication.

By displaying not only the response letter t5 but also the entry/exit of the extension subscriber, the person making the emergency call does not have to rush to the unoccupied guest room, and can only make an emergency call for the guest room that is currently occupied. Since the status can be monitored, evacuation guidance can be performed reliably and quickly in an emergency situation.
