The call / control unit 45 controls transmission and reception related to a call, and plays a role of inputting a sound source through a microphone or playing a sound source through a speaker.

The microcomputer 46 controls the entire system, and transmits the changed information to the emergency bell terminal 60 by controlling the system for the received change information input to the computer terminal, from the emergency bell terminal 60 Deliver the received signal to the computer.

An information change method using the public telephone network of the present invention using the system configured as described above will be described with reference to the flute chart of FIG.

Referring to the drawings, the present invention uses the keyboard of the computer terminal 30 in the remote management room 10 when changing the information stored in the emergency bell terminal 60 in the household at a remote location, for example, the incoming call number or sensor information. The information to be changed is inputted. (S31)

The information input through the computer terminal 30 is transferred to the microcomputer 46 according to the RS-232C protocol through the serial communication unit 41 of the center device 40, the microcomputer 46 is a computer by a preset program Information transmitted from the terminal 30 is transmitted to the emergency bell terminal 60 through the public telephone network through the public telephone network.

In more detail, the method of changing information and the method of transferring the information may be requested to change the subscriber information to the remote management office 10 by using a web, a telephone, or a medium accessible to the system of the present invention. .

After confirming the subscriber information for the subscriber requesting the information change, the manager stores the requested change information in the database of the computer terminal 30 to perform over-dating.

In such a state, the administrator changes the information through the computer terminal 30 at the request of the information change request of the subscriber, and prepares to transmit the change information by instructing the subscriber not to occupy the trunk line so that the incoming call can be made automatically. It is desirable to complete.

Subsequently, the computer terminal 30 transmits the change information stored in the database through serial communication to request the center device 40 to change the subscriber information, and the change information transmitted from the computer terminal 30 is transmitted to the center device ( 40 is input to the microcomputer 46 through the serial communication unit 41, the microcomputer 46 transmits the change information to the emergency bell terminal 60 while controlling the system by a preset program.

The present invention transmits the change information to the emergency bell terminal 60 using the public telephone network as described above in order to transmit the change information, wherein the center device 40 uses the public telephone network to change the information changed by the method described below. To transmit.

That is, when the information change start command of the administrator of the present invention is input, the computer terminal 30 controls the VOIP gateway 50 connected to the LAN to transmit the DTMF signal to the microcomputer 46 of the center device 40, and the microcomputer At 46, dialing is attempted via the DTMF transmitting / receiving unit 44. (S32-S33)

At this time, the VOIP gateway 50 checks the ringback tone signal and busy signal transmitted from the switching center (not shown), and when the busy signal is received, terminates the trunk line and retry dialing. The preset occupation time of the trunk line is checked. (S34)

At this time, when the emergency bell terminal 60 is hook-on state, but when the preset trunk line occupancy time elapses, the VOIP gateway 50 ends the trunk line and attempts to redial, and conversely, the emergency bell terminal 60 hooks off. If the signal is checked, the center device 40 resets the trunk line occupation time (S35-S38).

Here, the reason for resetting the trunk line occupancy time is that the time for transmitting the information is insufficient when the time when the hook-off signal is checked occupies most of the time set for checking the ring signal. By resetting the occupation time of the trunk line, the communication line is not disconnected in excess of the set time during the transmission of information.

In step 38, when the trunk line occupancy time is reset in the hook-off state, the center device 40 transmits the information transmitted from the computer terminal 30, wherein the transmission information is, for example, information to be changed, subscriber's phone. Special operation information for setting the number, subscriber password, sensor detection time and the like is transmitted (S39).

As such, when information is transmitted from the center device 40 of the remote management room 10 to the emergency bell terminal 60 in the household, the center device 40 checks the change completion response signal from the emergency bell terminal 60, and for a predetermined time. If there is no response signal, it tries to redial after completing CO line. On the contrary, when a response signal is transmitted from the emergency bell terminal 60, the check signal has a confirmation procedure for the information transmitted in step 39, and the confirmation procedure receives the changed information received from the emergency bell terminal 60. This completes the confirmation procedure by sending a response signal to the center device 40, which has been normally performed (S40-S41).

At this time, the center device 40 automatically terminates the trunk line and attempts to redial if there is no response signal from the emergency bell terminal 60 within the set time for a response to the transmitted change information. On the contrary, when the response signal is received from the emergency bell terminal 60, the center device 40 changes the update data for the subscriber file, checks the subscriber list stored in the computer terminal 30, and then goes to the emergency bell terminal 60. The trunk line ending signal is transmitted and terminated (S42-S44).

As a result, the emergency bell terminal 60 stores the information change date and the change time of the subscriber in the subscriber information database based on this signal, thereby causing an emergency within the household to be monitored and pressing the emergency button of the emergency bell terminal 60. If you press, the call is transferred to the changed phone number (information) and connected to the manager, an external family member or the attending physician to recognize a signal or make a call.

As described above, the present invention allows an internal administrator or an external person to change the information through a public telephone network in a remote place, when he or she wants to change information such as a telephone number that can receive an emergency signal sent in case of an emergency. The administrator can easily change the input information of the emergency bell terminal without visiting each household.
