Description

Emergency rescue dialing method in private exchange {Method for emergent dialing in private branch exchange}

The present invention relates to a dialing method of a private exchange. Particularly, when a life-threatening situation occurs due to armed robbery or fire in a shopping mall or a bank in which a private exchange is installed, an extension-restricted extension subscriber only off-hooks or picks up a handset. The present invention relates to a method of emergency rescue dialing of a private switchboard so that a simple operation of pressing a function button is suitable for making an emergency rescue request for an emergency rescue broadcast and a police station.

Hereinafter, a conventional emergency rescue method will be described.

First, Figure 1 is a block diagram of a general private exchange.

As shown in this, when an emergency occurs, the extension subscriber requests an emergency rescue to the external emergency rescue center 13 through the telephone 11 connected to the simple switch 12. That is, the user picks up the handset and directly dials the emergency rescue telephone number (such as 112 or 119) or waits for a response from the other party by quickly dialing using a shortcut key or the like. Therefore, when the other party responds, the emergency rescue request is made.

Alternatively, if a separate alarm system is prepared for emergency situations such as crime prevention / fire prevention, the above alarm system transmits an alarm signal to a certain area within the building when a specific alarm bell rings when an emergency situation occurs. It will automatically connect to the emergency center and request emergency rescue.

However, in the conventional technology as described above, in case of an emergency, the user has to dial up the handset in an urgent situation, and wait for the response of the other party to explain the emergency situation by hand, thus delaying the first aid or risking the user. There was a problem that the user is not sufficiently secured by exposing to.

In addition, when equipped with a separate alarm equipment for emergency, such as crime prevention / fire prevention, there was a disadvantage that the additional installation cost and maintenance costs must be added.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, an object of the present invention is to extend the station subscriber limited movement in the event of a dangerous situation in the place where the private exchange is installed off hook only the receiver or a specific function button By operating the system, it is possible to provide an emergency rescue dialing method of a private exchange that can broadcast rescue requests to other areas in the building and dial emergency rescue telephone numbers.

In order to achieve the above object, the emergency rescue dialing method of the private exchange according to the present invention includes a voice message and a specific broadcasting zone number and emergency broadcast for broadcasting to a specific area during an emergency rescue dial and requesting rescue to an external emergency rescue center. After the rescue phone number is stored in the database in advance, the emergency subscriber dials the emergency function dial by pressing a specific function button of the extension terminal or turning off the receiver in an emergency. And then performing an emergency broadcasting step of broadcasting the emergency rescue voice message stored in the database to a specific broadcasting area, and continuously dialing the emergency rescue telephone number stored in the database to transmit the emergency rescue message to the called party. It is characterized by the technical configuration thereof.

Referring to one embodiment according to the technical idea of the emergency rescue dial method of the private exchange according to the present invention configured as described above are as follows.

First, FIG. 2 is a block diagram of a private switch to which the present invention is applied. FIG. 3 is a flowchart of an emergency rescue dialing method of the private switch according to the present invention.

As shown in the drawing, the method includes a database of voice messages, specific broadcast area numbers, and emergency telephone numbers, which are broadcast to a specific area 24 at the time of an emergency call and are requested to the external emergency center 25. A storage step ST21 for storing in advance in step 23); A dial step (ST22) in which the extension subscribers off-hook the receiver 21 in an emergency after the storing step (ST21) to allow a predetermined time to elapse or press a specific function button to make an emergency rescue dial; An emergency broadcasting step (ST23 to ST24) for broadcasting a voice message stored in the database 23 to a specific broadcasting area 24 when the dialing step ST22 is performed; When the emergency broadcast step (ST23 ~ ST24) is carried out is composed of an emergency call step (ST25 ~ ST28) for transmitting an emergency rescue message to the called party by dialing the emergency rescue telephone number stored in the database (23).

Hereinafter, the flow of the emergency rescue dial method of the private exchange according to the present invention according to the above configuration will be described in detail.

First, in the storage step ST21, in preparation for an emergency situation, a message to be used for emergency rescue dialing of the private exchange is recorded by voice. The voice message recorded in this way is pre-programmed and stored in the database 23 so as to be correlated with emergency rescue telephone numbers such as the external emergency rescue center 25 and broadcasting zone 24 information such as a security office.

At this time, if the emergency call is to be made by off-hooking the handset of the terminal 21, a warm line function of the private switch 22 is carried out when the terminal is not operated for a predetermined time. Program as described above, and in order to be an emergency rescue dial by pressing a function button is programmed as a specific function button that can be programmed as described above.

In addition, the memory of the database 23 should use static RAM so that the corresponding data is not lost even in a non-powered state.

Subsequently, in the dialing step ST22, when an emergency situation such as armed strength or a fire occurs, the extension user of the private exchange 22 uses the terminal 21 to make an emergency rescue dial. At this time, the extension user whose behavior is restricted due to the threat of life may turn off the handset of the terminal 21 and allow a certain time to elapse without additional terminal manipulation, or by pressing a specific function button of the terminal 21 in an emergency situation. It is possible to perform a dial according to (ST22).

Then, the private exchange 22 does not expose the terminal user performing the emergency dial to a dangerous situation by displaying a characteristic mark on the terminal 21 performing the emergency rescue dialing. Will be done.

Thus, when the emergency rescue dial of the dial step ST22 is performed, in the emergency broadcast steps ST23 to ST24, the emergency rescue voice message and related broadcast area information are retrieved from the database 23 (ST23). The emergency rescue voice message is broadcast to a specific broadcasting zone 24 such as an associated guard room (ST24).

In this case, emergency rescue broadcast is made to a specific broadcasting zone 24 retrieved from the database 23, but an extension user who makes a rescue request so that the terminal 21 which has performed emergency rescue dialing does not become an emergency rescue broadcast in a corresponding extension zone. Will not be exposed.

And in the emergency call step (ST25 ~ ST28), after performing the emergency broadcast step to retrieve the emergency rescue phone number associated with the emergency rescue voice message in the database (23) (ST25) emergency rescue center through the available trunk line (25) And the like (ST26), and then the other party's response is detected (ST27) and the emergency rescue voice message is transmitted to the other party (ST28).

At this time, if the available CO line is an analog CO line, the private switch 22 switches the tone detection circuit to detect the tone to the CO line and then sends the corresponding emergency rescue message to the CO line if the tone from the other station changes from ringback tone to silent. Will be sent. And if the available trunk line is an Integrated Services Digital Network (ISDN) or a digital trunk line that can recognize the other party's response at the private exchange 22, the private exchange 22 dials the telephone number and, if there is a response from the other party, It will recognize the connection and then send the emergency voice message to the CO line.

As described above, the present invention stores the emergency rescue message, the specific broadcasting area number and the emergency telephone number in a database in advance, and the user of the terminal, which is restricted in behavior when an emergency occurs, does not expose himself to danger. It is to allow the delivery of rescue messages to the outside world.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
