DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange and, more particularly, to a private branch exchange accommodating a private MCA radio telephone.

[0002]

2. Description of the Related Art In a conventional private electronic exchange, after automatically receiving alarm information detected and detected by a sensor through an external computer, it is not possible to report the alarm information to a wireless telephone of a private MCA.

[0003]

In this conventional private-use electronic exchange, a sensor automatically receives, through an external computer, alarm information predicted and detected by a sensor, and then receives the alarm information.
Since it was not possible to notify the CA wireless telephone, even if a disaster was detected, the mobile MCA for the campus was automatically carried.
Could not be alerted through this wireless telephone.

[0004]

A private branch exchange according to the present invention comprises a wireless telephone of a private MCA, a connecting device for accommodating the wireless telephone, and a connecting device connected to a time-division switch. , A central controller for controlling the wireless telephone via the line controller and the connecting device, and an interface controller connected to the central controller and connected to an external computer via a bus To the external computer
A first unit for identifying location registration information of the wireless telephone; anda warning information predicted by the detection information of the sensor. A second means for sending to the central control, a third means for transmitting the alarm information of the reception to the wireless telephone whose location is registered, and a fourth means for displaying the alarm information on the wireless telephone. Have.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

The private branch exchange according to the present embodiment is connected to a time-division switch 1 so that the private MCA radio telephones 10 to 10 are connected.
And a line controller 4-5 for controlling the connection devices 6-9 in which 15 is accommodated, and these are centrally controlled by the central controller 2. Further, the central controller 2 is controlled by the interface controller 3 to control the interface bus 16.
Is connected on-line to an external computer 17 having a database 18 and sensors 19 to 20.

FIG. 2 shows a message format of alarm information sent from the external computer 17 to the interface control device 3 to the wireless telephones 10 to 15 of the private MCA via the interface bus 16 shown in FIG. The message format includes a message identifier 21 of the message itself, a message type 22 indicating the meaning of the message such as alarm information, etc., and a first information field 23 and a second information field 24 which can be added as necessary according to the meaning of the message type 22. And a third information field 25.

[0008] The sensors 19 to 20 are used for detecting weather, pressure, temperature,
When a change in weather conditions such as humidity and wind speed is sensitively detected, the change is notified to the external computer 17 as detection information.
The external computer 17 predicts the occurrence of a disaster based on the detection information collected from each of the sensors 19 to 20, and if a disaster is predicted, edits a warning message and sends a warning message to the interface control device 3 via the interface bus 16. Is sent. It should be noted that an alarm is issued to a radio telephone of a specific MCA for the premises or a M
It is possible to search for location registration information of a CA wireless telephone and specify a transmission destination.

Next, the contents of the message format will be described with reference to FIG. 2. The message identifier 21 is a (FF) 16 code indicating the start of a message, and the message type 22 is an (AA) ASC indicating an alarm command.
1 to (AC) ASC code. (AA) ASC2 in the case of an alarm to the radio telephone of the MCA for all premises
(A) is an alarm to a specific premises MCA radiotelephone, (A
B) When ASC2 is an alarm to a specific private MCA radio telephone, (AB) When ASC2 is an alarm to a private MCA radio telephone in the radio range of a specific connection device, (AC) A
SC2 is inserted into the message type 22. If the message type 22 is (AA) ASC2, and the blank is (AB) ASC2 in the first information field 23, the device number of the connection device is inserted.

In the second information field 24, an alarm type such as lightning strike or earthquake is inserted in a predetermined ASC2 code. The terminal control information such as the warning light or the warning character display information is also stored in the AS.
Inserted in C2 code.

The central control unit 2 has an interface bus 1
When an alarm message transferred from the interface controller 3 via the interface controller 6 is received, the contents of the message are analyzed, and the message type 22 and the first information field 23 are used to identify the local MCA radio telephone to be alarmed. Subsequently, a second information field 24 and a third information field 25
The type of alarm and terminal control information are identified from the contents of the above, the connection devices 6 to 9 are controlled via the line control devices 4 to 5, and an alarm sound or an alarm light is sent to the target on-premise MCA radio telephones 10 to 15. Alternatively, terminal notification control such as display of a warning character is performed to draw the user's attention, and information such as details of disasters / warnings and instructions for evacuation sites is provided.

[0012]

As described above, according to the present invention, a lightning strike is performed by automatically receiving, through an external computer, alarm information predicted and detected by a sensor, and then notifying the alarm information to a wireless telephone of an on-premise MCA. When a disaster such as an earthquake, a tsunami, or an avalanche is predicted, alarm information can be automatically sent to the mobile telephone of the MCA for the premises being carried.
