Next, the detailed operation of the multiprocessor will be described with reference to the sequence chart shown in FIG. FIG. 3 shows an operation sequence of the multiprocessor 3 which analyzes the event information from the 32-circuit trunk line 2 and sends the instruction information to the corresponding CS device interface trunk 5.

The multiprocessor 3 monitors the request information sent from the 32 circuit trunk line trunk 2 and the CS device interface trunk 5 at a cycle of 16 ms.

As shown in FIG. 3, when the multiprocessor 3 receives the request signal from the 32-circuit trunk line trunk 2, it sends an interrupt signal to retrieve the event information from the 32-circuit trunk line trunk 2.

When the event information is the incoming information to the PHS terminal, the CS device interface trunk 5 accommodating the corresponding PHS terminal is captured, and the interrupt signal and the PHS call information are sequentially transmitted to the trunk. .

The above-mentioned processing of the multiprocessor is similarly performed in the processing when the information from the CS device interface trunk 5 is received and sent to the 32-circuit trunk line trunk 2.

Next, the operation of the nurse call system having the above configuration will be described with reference to the flow charts shown in FIGS.

For example, when a call is made from the nurse call slave unit 6 connected to the first nurse call unit 7, the first nurse call unit 7 receives the call from the nurse call slave unit 6 and makes a nurse call. ID, room number,
The bet number and the PHS terminal number (N = 1 to 8) are added to the calling information and the calling information is sent to the 32-circuit trunk line trunk 2 mounted on the digital exchange 1. FIG. 6A shows the structure of the data sent from the first nurse call device 7 to the 32-circuit trunk line trunk 2.

When the RS232C interface unit 13 receives the data from the first nurse call device 7 (step S1), the 32-circuit trunk line trunk 2 analyzes the received information by the first multiprocessor interface unit 22 and calls it. It is checked whether it is information (step S2).

When the data received from the first nurse call device 7 is call information, the 32-circuit trunk line 2 adds the first nurse call to the "incoming" command information which is the existing interface information of the digital exchange 1. The nurse call ID, room number, and PHS terminal number N received from the device are added (step S3) and sent to the multiprocessor 3 which controls the digital exchange in circuit units (step S4). FIG. 6B shows the structure of data transmitted from the 32-circuit trunk line trunk 2 to the multiprocessor 3.

When the multiprocessor 3 for controlling the digital exchange receives the incoming call information from the 32-circuit trunk line trunk 2, the nurse call ID and the PHS terminal which are the information from the first nurse call device added to the incoming call information. The number N is taken out and converted by the reception number conversion unit 4 into the PHS terminal number of the nurse's mobile that matches the interface of the CS device interface trunk (step S5). Then, the CS device interface trunk 5 accommodating the corresponding PHS terminal is captured.

The captured CS device interface trunk 5 calls the PHS terminal 12 of the nurse's cell housed in the corresponding CS device 11.

If the information sent from the first nurse call device 7 is not call information as a result of analysis by the first multiprocessor interface section 22 of the 32-circuit trunk line trunk 2 (step S2 / NO), The nurse call ID, the room number, and the PHS terminal number N received from the first nurse call device are added to the "response" command information that is the existing interface information of the digital exchange 1 (step S7), and the digital exchange 1 is provided for each circuit.
To the multiprocessor 2 which controls the (step S
8).

When receiving the response command information, the multiprocessor 3 for controlling the digital exchange 1 instructs the CS device interface trunk 5 accommodating the corresponding PHS terminal 12 to make a response to start the call (step S9). ). In this case, the 32-circuit trunk line trunk 2 and the digital exchange 1 are connected to each other through the communication path.

Further, as a result of analyzing the information sent from the first nurse call device 7 by the first multiprocessor interface section 22 of the 32-circuit trunk line trunk 2, if the call is restored (step S2 / NO), it is received. The converted information is converted into the "recovery" command information which is the existing interface information of the digital exchange 1 (step S7) and sent to the multiprocessor 3 which controls the digital exchange 1. The call recovery is a process of stopping the call to the PHS terminals other than the PHS terminal that has received the response when the call to the plurality of PHS terminals that can be called from the nurse call device is made.

The multiprocessor 3, which has received the "recovery" command information, receives all the PHSs that have been called in advance.
It instructs the CS device interface trunk 5 accommodating the terminal 12 to restore. Upon receiving the instruction, the CS device interface trunk stops calling the PHS terminal 12 of the nurse's cell housed in the corresponding CS device 11 (step S9).

Next, a call from the nurse's portable PHS terminal to the nurse call slave unit 6 or a nurse call slave unit 6 is made.
The operation in the case where the PHS terminal responds to the call from is described with reference to the flow shown in FIG.

When a call from the nurse's portable PHS terminal to the nurse call handset 6 or a response to the call from the nurse call handset 6 is made by the PHS terminal, C
The S device interface trunk 5 receives a call or a response from the CS device accommodating the nurse portable PHS terminal and sends it to the multiprocessor 3 which controls the digital exchange.

When the multiprocessor 3 for controlling the digital exchange 1 receives the information from the CS device interface trunk 5 (step S10), the reception number conversion unit 4 receives the nurse call ID / room number suitable for the interface of the nurse call device.・ It is converted into a bet number and a nurse call cordless handset number, and is added to the "response instruction" command information which is the existing interface information of the digital exchange 1 and 3
Send to the two-circuit trunk line trunk 2 (step S1)
1). Note that in FIG. 6C, multiprocessors 3 to 3 are shown.
The structure of command information sent to the two-circuit trunk line trunk 2 is shown.

Upon receiving the "response instruction" command information, the 32-circuit trunk line trunk 2 analyzes the information in the multiprocessor interface section. The result of the analysis,
If the "response instruction" command information is calling information from the PHS terminal, it is converted into "selective calling" information, "broadcast" information, etc. according to the analysis situation at that time (step S1).
2) Add the nurse call ID, room number, bed number, nurse call slave unit number data to that information,
Information is transmitted to the nurse call device via the 232C interface unit (step S13).

As a result of analyzing the received information in the multiprocessor interface unit, if the "response instruction" command information is a response to the call from the nurse call slave unit 7, it is converted into call response information ( In step S12), the nurse call ID, the room number, the bet number, and the nurse call handset number data are added to the nurse call device that was involved in the call from the nurse call handset.
The data is transmitted via the S232C interface unit (step S13). After that, by switching the call circuit by the switching and call processing unit 21 of the 32-circuit trunk line and the multiprocessor 3, the call between the nurse call handset 6 and the PHS terminal 12 becomes possible.

S232C interface unit 15, third RS232C
Either one of the interface unit 17 and the fourth RS232C interface unit 19 may be used, but the interface on the multiprocessor side has eight communication channels and one
Since it is one control circuit, two of the four multiprocessor interface units are used.

In FIG. 5, a fifth nurse call device having a control function capable of calling 16 PHS terminals is shown.
