This system automatically dials a predetermined location such as a relative, hospital, welfare office, etc. by pressing a button attached to the telephone, and sends out the contents of a prerecorded tape.

[Problem to be solved by the invention] However, since these conventional devices are just telephones with additional functions, they are basically telephones and have a shape corresponding to that, so they can be placed freely. Since there are restrictions on the amount of use, there was a problem that it was not suitable to be placed freely at the bedside of a bedridden elderly person. Additionally, if the automatic dialing number changes, the person must go to the telephone at the elderly person's home and change the internal settings, so if an emergency occurs in the meantime, the situation may become irreparable. There was also the issue of keeping up.

[Means for Solving the Problems] In order to solve these problems, the present invention provides an intercom-type handheld device with a transmitting/receiving function and a one-touch call button for the first problem. It is. To solve the second problem, we have made it possible to set an automatic destination number for the nursing home equipment (hereinafter referred to as a slave station) from the other party (hereinafter referred to as the master station) that is connected by automatic dialing. be.

[Operation] By pressing a push button on the handheld device, a call is automatically made to a predetermined master station. Multiple master stations can be set,
If one of the master stations is busy, a connection will be made to the other master stations, and if all the master stations are busy, the master stations will be selected one after another until one becomes free and the call will be made automatically. will be held. Further, the telephone number of the master station can be changed by remote control from one of the numbers determined as the master station.

[Example] FIG. 5 is a block diagram showing the overall configuration of this device,
There is a master station 3 connected by telephone line 2 to a slave station 1 placed in an elderly person's home. In the figure, only one master station is shown, but slave station 1 can be connected to multiple master stations. It has become (
In this embodiment, the number of master stations is assumed to be 2).

The slave station 1 includes a main device 11, a telephone 12, and an intercom-type handset 1 that can be placed at the bedside of an elderly person. It consists of The master station 3 includes a main device 3K, a telephone 3□, a host computer 33, a display 34, a printer 35, and a handset 3.
It consists of 6. Although not shown, the handset 36 is mounted on a handset holder provided in the main device. When the handset is placed on the handset holder, it is in an on-hook state.
It is designed so that when you remove the handset, it goes off-hook.

Figures 1 to 4 are flowcharts showing the operation of Figure 5. Figure 1 is the operation of the slave station when discharging from the slave station, Figure 2 is the operation of the master station at that time, and the operation of the slave station at that time. FIG. 3 shows the operation of the master station when the dial memory of the slave station is rewritten, and FIG. 4 shows the operation when the slave station receives a call and rewrites the dial memory.

When the call button 130 provided on the handset 13 of the slave station 1 is pressed as shown in step 100 in FIG. When connected to the parent station by auto-dial, a ring tone is detected in step 200, and the process proceeds to step 201, as shown in FIG. The buzzer beep processing is performed as shown. Then, as shown in step 202, when one af3x is off-hook, the process of switching the station line to the main unit 31 side and the process of sending out the master station tone are performed as shown in steps 203 and 204. For example, tones for dial numbers 1, 2, 3°4.5 are sent out in series for a certain period of time.

When this tone is sent from the master station, the slave station determines whether it has received the master station tone, as shown in step 104 in FIG. If the tone cannot be received here, as shown in step 105, auto-dial processing is performed to the master station B.

The case in which tones cannot be received includes not only the case in which all tones cannot be received, but also the case in which all five waves cannot be received accurately. If the tone cannot be received in step 104, the system waits for 3 seconds, goes on-hook once, performs an off-hook, and then auto-dials to the master station B.

When the auto-dial is completed, it is determined again in step 106 whether the master station tone has been received, and if the master station tone cannot be received here, it is determined in step 107 that a time has elapsed. This time-over is such that if the master station tone is not received for a predetermined period of time, the process returns to step 103, which auto-dials to the master station, and the master station tone is not sent from either the master station or the parent station. As shown in step 108, only when the master station tone cannot be received for a predetermined period of time and the number of repetitions reaches a predetermined number of times is YES in step 107, and as shown in step 108, the master station tone is not received for a predetermined period of time, e.g. After maintaining the on-hook state for a minute, the process returns to step 103. In addition.

This is because the processing in step 108 complies with the matters determined by NTT's technical standards.

When reception of the master station tone is detected in step 104 or step 106, the own telephone number is sent out as shown in step 109.

This telephone number is sent to the master station and is sent to step 205 in Figure 2.
Detected in Here, continue sending the phone number 3
When the same number is received at least twice, the master station that receives the call determines that the call was received correctly.

When the telephone number of the slave station is received, the master station displays the telephone number on the display 34 as shown in step 206 of FIG. 2, and displays the slave station telephone number on the host computer 32 as shown in steps 207 to 209. The master station tone is sent to the slave station, and the call status is set.

The master station tone sent out in step 208 is transmitted to the slave station, and when received in step 110 of FIG. 1, the slave station stops the melody and enters a talking state as shown in step 111. The slave station is structured so that hands-free calls can be made using the handset 13, and the handset 1 can be placed at the bedside.
．． You can make a call by simply speaking towards the person.

A call to the parent station is made by the handset 36, and when the call is finished, the handset 36 is returned to the handset receiver, and the hook switch is operated thereby to be on-hook, and step 210 in FIG. Determine on-hook, step 211
After transmitting the master station tone as shown in step 2],
As shown in 2, the process of returning the central office line to the telephone side is performed.

The master station tone sent in the previous step 211 is transmitted by the slave station, and when it is determined that the master station tone has been received in step 112 of FIG. 1, the slave station also returns the central office line to the telephone side as shown in step 113. Processing takes place. Step 1
If the master station tone cannot be received in step 12, step 114
After three minutes have elapsed, the process of step 113 is performed.

If the telephone area number of the master station changes, it is necessary to rewrite the dial memory of the slave station. At this time, the master station receives telephone number data from the host computer 33 as shown in step 300 in FIG.
Processes automatic dialing to slave stations. As a result, the slave station detects the bell tone as shown in step 400 of FIG. At this time, if the slave station responds, step 40
By pressing the call button 130 as shown in step 1, the central office line is switched to the main device side as shown in step 402. Also, even if the call button is not pressed, step 403
When the bell rings, for example, 15 times as shown in FIG. 2, the process of switching the central office line to the main device side in step 402 is performed.

Thereafter, as shown in step 404, the slave station tone is transmitted, and this tone is transmitted to the master station, and the slave station tone is detected in step 303 of FIG.

When the tone is received, processing for transmitting telephone number data to the slave station is performed as shown in step 304.

The telephone number data is sent to the slave station at step 405 in Figure 4.
It is determined whether the telephone number data is received. At this time, the telephone number data sent from the master station is sent three times, and when the same telephone number data is confirmed twice or more at the slave station, it is assumed that the telephone number data has been accurately received. Once the telephone number data is received, steps 406.407.
As shown at 408, the telephone number memory is rewritten, the slave station tone is sent out, and the central office line is returned to the telephone side.

When the slave station tone sent in step 407 is received in step 305 at the master station, the master station receives it in step 306.
, 307, and 308, processing for transmitting a master station tone, processing for transmitting completion to the host computer, and processing for returning the office line to the telephone side are performed in sequence.

If the slave station tone cannot be received in step 303, it is determined whether the time has elapsed in step 309, and then the process of transmitting an error to the host computer as shown in step 310 is performed, and then the process of step 308 is performed, and the process of step 305 is performed. If the slave station tone cannot be received at step 310, an error message is sent to the host computer, and then processing is performed to return the central office line to the telephone side.

When the master station calls the slave station to make a call, the process up to step 404 in FIG. Processing is performed to place the slave station in a talking state. When the call ends, the master station places the handset 36 on the handset holder (not shown) of the main device as described above, so that the master station tone is transmitted, which is received as shown in step 410, so that the master station At the office, processing is performed to return the office line to the telephone set, as shown in step 408. However, step 40 is the same as when talking to a normal phone.
