In the event of an emergency, the user
It is possible to make an emergency call to the center side by pressing the button of the wireless transmitter 161 that is being carried or the emergency button 163. Further, the user can have a health consultation with the doctor at the center simply by pressing the consultation button 164.

The operation of the home medical care management system having the above configuration will be described. Here, as an example, it is assumed that the emergency button 163 of the home adapter 12-1 (FIG. 3) is pressed and then the emergency button 58 of another home adapter 12-2 is pressed. First, home adapter 12
When the -1 emergency button 163 is pressed, the CPU 136 detects this and the center 17 registered in the ROM 137 is detected.
The telephone number shown in FIG. 1 is read out, and the corresponding dial number is sent from the modem / DTMF transmitting unit 142 to the NCU 149. Upon receiving this, the NCU 149 automatically dials the telephone number.

Hereinafter, along with FIG. 4, the MCC 18 (FIG. 1,
The operation of FIG. 2) will be described. Here, home adapter 12
The telephone line 13 is sent from the center 17 side by the call from -1.
It is assumed that the first line management unit 28-1 of the MCC 18 is called via -1.

First, when the ringer of the NCU 40-1 is activated (step S101), the NCU 40-1 establishes a line connection by a predetermined protocol (step S102). Here, when the connection by the modem is not normally performed (step S103; N), the NCU 40-1 disconnects the line (step S104) and ends the reception operation. On the other hand, if the connection is made normally (step S103;
Y), line management CPU 32-1 is home adapter 12-1
The notification information sent from is received, and it is detected whether or not the home adapter ID is present in the received information (step S1).
05).

Here, the notification information sent from the home adapter includes a message including a home adapter ID and a notification type such as emergency or consultation.

When the home adapter ID is detected (step S106), the line management CPU 32-1 writes the received content in the DPRAM 33-1 (step S1).
07) Next, the interrupt controller 34-1 sends an interrupt signal to the notification control CPU 24 (step S10).
8).

The notification control CPU 24 detects from the sent interrupt signal that this is the one sent from the line management unit 28-1 (step S109) and reads the message from the corresponding DPRAM 33-1. (Step S110), a command packet as shown in FIG. 5 is created. This command packet is one in which node information 77 indicating the transmission destination and the reception destination is added to the message section 78. For example, the line management CPUs 32-1 to 32-3
Node addresses of "40", "41", "4"
2 ", the node address of the notification control CPU 24 is" 3 "
0 ", the node address of the host computer 19 is" 2 "
Therefore, the node information is “4020” in the case of the notification from the line management CPU 32-1 to the host computer 19.

The notification control CPU 24 that has created such a command packet checks the state of the RS232C line 20 and if it is in the ready state (step S112;
Y), send this command packet to the host computer 19
(Step S113).

The host computer 19 receives the command packet, recognizes from the node information 77 (FIG. 5) that this packet is from the line management unit 28-1, and further analyzes the contents of the message unit 78. Display output is performed. As a result, the operator on the center side
Operate the host computer 19 to operate the home adapter 12-
A videophone (not shown) on the first side is remotely activated to monitor the state of the user, or the home adapter 12-
The necessary processing can be instructed by contacting the local civil servants, etc. near the user's home.

Now, in the above procedure, the line management unit 2
If the emergency button of another home adapter 12-2 is pressed during reception processing by 8-1, the second line management unit 28-2 performs reception processing this time. The operation in this case is also similar to that in the case of the first line management unit 28-1 described above.

In this way, the MCC 18 in this embodiment is
Can perform reception processing for up to three emergency calls at the same time, and the received message is sent to each DPRAM 33-
1 to 33-3, respectively. Since the host computer 19 is capable of multitask processing, it is possible to read out these plural messages and perform other processing in parallel. The number of line management units provided in the MCC 18 is not limited to three, and more lines may be provided.

Further, in this embodiment, the MCC 18 creates the command packet at the time of reception, but it may be executed by the line management CPU in each line management unit.

In this embodiment, the reception operation on the center side has been described, but the transmission is performed in the reverse order of the above procedure.
That is, for example, when giving a necessary command to the home adapter 12-3, the host computer 19 creates a command packet or a response packet containing necessary information and sends it to the MCC 18. On the MCC18 side,
The notification control CPU 24 analyzes this and detects from the node information that the transmission destination is the line management unit 28-3. Then, the message is written in the DPRAM 33-3 in the line management unit 28-3, and the fact is notified to the corresponding interrupt controller 34-3. Interrupt controller 34
-3 sends an interrupt signal to the line management CPU 32-3. Upon receiving this, the line management CPU 32-3 changes the DPRA
Read the message from M33-3, and use the modem / DT
Transmission to the home adapter 12-3 via the telephone line 13-3 under the control of the MF transmitting unit 37-3 and the NCU 40-3.

In this way, the command and response can be sent from the center 17 side to the desired home adapter.

By the way, in order to monitor the notifications from the line management CPUs 32-1 to 32-3 by the notification control CPU 24, the following method may be used in addition to the above interruption.

That is, when a notification is received, instead of outputting an interrupt signal from the line management CPUs 32-1 to 32-3, a flag indicating that the notification has been received is set in each DPRAM, and the notification control CPU 24 Monitors the status of each flag by polling. Then, if the flag is set, the notification control CPU 24 may execute the processing from step S110 of the flowchart of FIG.

[0044]

As described above, according to the present invention,
We decided to provide a line management means for each telephone line, receive it, add node information to the received contents and send it to the host computer, so even if there are emergency calls from multiple home adapters at the same time The host computer can recognize which line the emergency call is from from the node information. Therefore, multiple reception is possible at one center, and there is an effect that it is possible to quickly respond to a plurality of simultaneous emergency calls.
