Abstract

PURPOSE:To obtain a system notifying emergency information to an information adressee by a simple operation promptly and surely. CONSTITUTION:When a master station M performs a transmission information operation to a slave station S and detects the response of the slave station S, the master station transmits a message with emergency information to the slave station S, and when the salve station S listens to the message and performs a mode switching operation, the slave station transmits a mode switching signal and transforms its own station to a data mode. When the master station M receives the mode switching signal, transforms its own station to a data mode and transmits emergency information, and the slave station S receives the emergency information and performs a reception confirmation operation, reception confirmation data is transmitted to the master station M and the reception confirmation of the emergency information by the slave station S is taken at the master station M. When the slave station S is busy or performs no response and when the reception confirmation data can not be received at the master station M, the master station M repeats the transmission information to the slave station S. Thus, the transmission information operation is easy and the prompt transmission information is enabled because the transmission information is performed for all the slave stations S by the transmission information operation of one time at the master station M and information is surely transmitted because the transmission information is repeated till the reception at the slave station S is confirmed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency information reporting system of an emergency reporting system. For example, dam managers, river managers, etc., can use the information about the discharge of dams and other abnormalities in river management facilities such as dams, levees, and locks. An optimal emergency call system that accurately transmits emergency information, such as emergency information for preventing disasters to downstream areas caused by conditions, to safety assurance officers in multiple downstream areas in a short time. It relates to an emergency information reporting method.

[0002]

2. Description of the Related Art Conventional emergency information is transmitted by a single-function telephone installed at the management office of dams, rivers, etc., which sends emergency information, and at the locations of a plurality of receivers (safety officers) of downstream areas. It is done by telephone fax, and it takes a huge amount of time to transmit accurate emergency information to a large number of call recipients.

[0003]

Since the conventional emergency information transmission is carried out by a single-function telephone or a telephone fax via a general subscriber telephone line or a dedicated telephone line, the emergency information is transmitted when the single-function telephone is used. It is necessary for the managers of dams, rivers, etc. that transmit the information to accurately convey the contents of the emergency information verbally, and for each safety assurance officer in the downstream area to hear the contents accurately. Requires meticulous attention and a long time, and when using a telephone fax, it is not clear from the administrator side whether or not the contents were transmitted to the security officer, so prompt communication of emergency information, There is a problem with certainty.

The present invention is proposed to solve these problems, and it is an object of the present invention to secure promptness and certainty of emergency information transmission, and further to save labor in emergency information notification. Is.

[0005]

In order to solve the above problems, the present invention joins a parent station (emergency information transmitting station) for reporting emergency information and a slave station (emergency information receiving station) for receiving emergency information. By connecting with a telephone line, the master station and the slave station can be set to switch to either voice mode or data mode, both sides are in voice mode during standby, and when an emergency occurs, The master station sends a call to the slave station and first sends an emergency information sending message in the voice mode to inform that the emergency information will be sent. The slave station receives the message and performs a mode switching operation to perform a mode switching signal. To the master station in voice mode, then automatically switches itself to the data mode, and the master station receives the mode switching signal and switches itself to the data mode and sends emergency information to the slave station. However, the child station sends the above emergency information. Shin to record the emergency information, or / and is intended to be displayed, also, the master station 1
In an emergency notification system in which a plurality of slave stations are provided for each station, the above-mentioned master station makes a call automatically to each slave station in order according to a predetermined order, and is busy or there is no response. If there is a slave station or a slave station that does not send the mode switching signal (hereinafter referred to as a slave station that cannot transmit information), the connection with the slave station that cannot transmit information is disconnected and the slave station in the next order After the call to each slave station has completed one cycle, the above-mentioned information transmission impossible slave stations are sequentially re-called. When the number of times the information cannot be transmitted remains when the number of times reaches the number of times, the parent station displays the information not-transmittable child station and displays a warning.

Further, according to the present invention, in order to confirm the reception of the emergency information at the slave station by the master station, the slave station receives the emergency information, confirms the reception, and then performs a reception confirmation operation. The reception confirmation data of the emergency information is transmitted to the parent station in the data mode, and the reception confirmation data is recorded and / or displayed on the relevant parent station. In order to confirm the receipt by the responsible person, including the name and operation time of the person who performed the reception confirmation operation in the reception confirmation data, the emergency information recorded or / and displayed in the slave station concerned is displayed. The print output from the printer is linked with the reception confirmation operation.

Further, when there are a plurality of slave stations, the slave stations that do not send the reception confirmation data of the emergency information (hereinafter,
It is called an unconfirmed child station. A), the same control as the re-call control and the warning display control for the above-mentioned information-transmission-disabled slave station is performed.

[0008]

[Operation] When the incoming call is answered at the slave station, if the incoming call is to notify emergency information, a message (voice guide) to that effect is sent, and the mode switching operation is performed by listening to the message. If you do, both the transmitting station (master station) and the receiving station (slave station) of the emergency information will automatically switch from the voice mode to the data mode (without special conversion operation) and the above emergency information will be reported. Even if the telephone line is used as a normal telephone call, the telephone call and the data transmission of the emergency information can be clearly distinguished at the slave station, and the certainty of the emergency call can be secured and the data mode can be set. The automatic conversion of the call allows quickness of emergency calls.

Further, since the confirmation information is recorded and displayed in the master station by performing the reception confirmation operation of the emergency information in the slave station, the master station side can confirm that the emergency information has been reliably transmitted to the slave station. In particular, by including the name and confirmation time of the reception confirmation person in the reception confirmation data transmitted by the reception confirmation operation, the recipient and the reception time of the emergency information can be confirmed at the master station.

Further, particularly when the slave stations are plural stations,
The master station sequentially calls each slave station to the slave stations that could not report emergency information (slave stations that cannot transmit information) or to the slave stations that could not confirm receipt of emergency information reports (slave stations that have not confirmed information reception). In this case, the repeat call is repeated, and when the number of repetitions reaches the set number, if the slave station remains, the master station displays the slave station and displays a warning.
Even when there are multiple slave stations, emergency information can be reported quickly and reliably.

1 is a block diagram of a network, FIG. 2 is a sequence diagram, FIG. 3 is a block diagram of a master station, FIG. 4 is a block diagram of a slave station, and FIG. 5A to 5C are flowcharts showing the operation of the master station, and FIG. 6 is a flowchart showing the operation of the slave station.

In the emergency call system according to the embodiment of the present invention, as shown in FIG. 1, the master station M is divided into a plurality of slave stations S1 to Sn.
Are connected by the subscriber telephone network N.

Taking the case where this system is used in river management as an example, the master station M is installed in a management office which issues emergency information such as dam discharge information, and the slave station S (interacts with multiple stations). When there is no need to distinguish between the two, the symbol is S.) is installed at a management office in the downstream area of the river, for example, which receives the emergency information.

The notification control sequence of the emergency notification system will be described with reference to FIG.

During standby, both the master station M and the slave station S are in the voice mode, and in this state, normal telephone call is possible.

[0016] For example, when an emergency situation that requires the discharge of a dam occurs, the master station M previously informs the information required in the downstream area (for example, the discharge time, the amount of discharged water, etc.) as emergency information ( (The device according to the present invention),
A report activation operation is performed.

As a result, the master station M calls the subscriber telephone network N to call the first-ranked slave station, for example, S1 among the slave stations stored in advance. A call signal arrives from the line network N, and the incoming call is displayed on the slave station S1.

When the slave station S1 responds to the incoming call, response information is sent from the slave station S1 to the master station M via the subscriber telephone line network N (normally, the slave station S1 is connected to the master station M). When the response of the slave station S1 is confirmed by this, the master station M sends an emergency information sending message for notifying that the emergency information will be sent to the slave station S1. The station S1 receives the above-mentioned emergency information sending message and outputs the sound. This message includes guidance for the mode switching operation to be performed next in the slave station S1.

From the above message, it is found that the incoming call is the incoming call for notifying the emergency information in the slave station S1,
When a mode switching operation is performed at the slave station S1, the slave station S1
A mode switching signal is transmitted from 1 to the master station M. This mode switching signal includes a DTMF (D
ual Tone Multi Frequency)
It uses signals and can be transmitted in voice mode.

After transmitting the mode switching signal, the slave station S1
The local station is switched from the voice mode to the data mode, and the master station M receives the mode switching signal and switches the local station from the voice mode to the data mode. That is, both the slave station S1 and the master station M are switched to the data mode by the mode switching operation at the slave station S1.

After switching to the data mode, the master station M to the slave station S
1, the emergency information is transmitted, and the emergency information is recorded and / or displayed in the slave station S1.

Although the notification of the emergency information from the master station M to the slave station S1 is completed as described above, in the present embodiment, in the slave station S1,
In order to confirm whether or not the emergency information has been thoroughly disseminated on the side of the master station M, the confirmation operation described below is performed.

In other words, the security officer of the receiving side management office confirms the emergency information displayed on the slave station S1 and the slave station S concerned.
When the reception confirmation operation is performed at 1, the slave station S1 to the master station M
The reception confirmation data is transmitted to, and the reception confirmation data is recorded and / or displayed in the master station M.

The receipt confirmation data includes a security officer name registered in advance and input by a receipt confirmation operation,
Since the data of the reception confirmation operation time is included, the name of the security officer who confirmed the reception at the slave station S1 and the reception confirmation time are displayed on the master station M, so that the transmission of emergency information is thoroughly known. It Also, if the security officer's PIN is required to be input for confirmation of receipt, the recipients of emergency information will be limited to specific persons, so notification of emergency information will be more strictly enforced. (Note that, as will be described later, if the reception confirmation operation is not performed in the slave station S, after disconnecting the line, the master station M calls the slave station S again and retransmits the emergency information.).

In addition, in the slave station S1, the reception confirmation operation causes the printer to print out the emergency information recorded in the slave station S1, thereby realizing the simplicity and speed of the operation. .

When the reception confirmation data is recorded or displayed in the master station M as described above, the master station M disconnects the line and re-converts itself from the data mode to the voice mode to move to the next higher level. After proceeding to call control for the slave station, for example, S2, and as described above, the slave station S1 which has notified the emergency information disconnects the line after sending the reception confirmation data or after printing the emergency information and returns to the standby state. In the standby state, the slave station S1 returns to the voice mode in preparation for the next incoming call.

The above-mentioned operations are the second or lower slave stations S2 to Sn.
To the slave station S2 from the master station M.
A call to ~ Sn is automatically made without requiring a start operation.

The above operation is the operation when the emergency information is received by the slave station S and can be confirmed by the master station M. When the slave station S is busy, a response operation is performed by the slave station S. If the slave station S does not perform the mode switching operation or the mode switching operation is not performed (when the slave station S is a slave station in which information cannot be transmitted), the master station M cannot transmit the emergency information, and the slave station S is urgent. When the reception confirmation operation is not performed after the information is received (when the slave station S is a slave station whose information has not been confirmed), the master station M cannot confirm the emergency information report. In such cases,
Recall from the master station M to the slave station S is tried as follows.

That is, in the master station M, when the busy tone is returned from the subscriber telephone line network N (when the called sub-station S is busy), the call is transmitted from the subscriber telephone line N within a set time after calling. When the response information (line polarity reversal) is not returned (when the called station S is not responding), when the mode switching signal is not returned from the called station S within the set time after the response information is returned (callee When the station S does not perform a mode switching operation) or when the reception confirmation data is not returned from the called substation S within the set time after the emergency information is sent (when the reception confirmation operation is not performed by the called substation S). Is the called substation S
After storing the slave station number of No. 1, the line is disconnected and the call control of the next slave station S is started.

When all the slave stations S1 to Sn have made a call, the master station M cannot transmit information and the information transmission-unconfirmed slave stations (hereinafter, when these two types of stations are collectively referred to as information-unachieved slave stations). ,) Is stored, and if there is no storage of the information unachieved slave station, the series of control is terminated,
When there is a memory of an information undelivered slave station, the information undelivered slave station is called again in sequence, emergency information can be transmitted, and the master station M confirms receipt of the information Erase the memory as.

The master station M automatically repeats the above-mentioned call to the information unreachable slave station and counts the number of automatic calls to each information unreachable slave station. When there is an information unachieved slave station remaining, the remaining information unachieved slave station is recorded and / or displayed, a warning is displayed, and a series of control ends.

With the above control, the master station M finally finds out the slave stations to which the emergency information could not be sent and the slave stations for which reception confirmation could not be obtained. Therefore, if necessary, another line can be connected to the slave station. You can take measures such as contacting at.

The configuration of the master station M will be described with reference to FIG.

An audible sound emitting unit 812 that emits an information sending message, a call circuit unit 813 used for a normal telephone call, a handset 814, and the like.

The operation of the master station M according to the embodiment will be described with reference to the processing flow shown in FIGS. Note that FIG. 5 (A) shows the control at the time of the first call to the slave stations S1 to Sn, and FIGS. 5 (B) and 5 (C) show the recurrence of the unreached slave station when the unreached slave station occurs. It shows the control at the time of calling.

For example, when an emergency occurs that requires dam discharge, the master station M first uses the keyboard 4
From this, an operation for inputting the emergency information creation command and inputting the data constituting the emergency information such as the discharge time and the amount of discharged water is performed. In the data processing unit 1, the input data is C
It is stored in the emergency information memory 102 as emergency information under the control of the PU 101.

First, referring to FIG. 5A, the operation at the time of the first call is described. The emergency information memory 10 is as described above.
After the emergency information is stored in advance in 2 and the alert activation operation is performed by the key operation of the keyboard 4 in the master station M (step S1), the CPU 101 in the data processing unit 1 causes the alert activation via the keyboard interface 106. The operation is read and the slave station number K stored in the slave station number memory 103 is designated. Immediately after the call initiation operation, the designation of the slave station number K is performed by designating the number (K) of the highest slave station S1 in the alerting order (the alerting order is S1, S2, S3, ... Sn). = 1) (step S2).

Next, the CPU 101 of the data processing unit 1
The call control command is issued to the line control unit 2, and the line control unit 2
Then, when the CPU 201 reads the calling command through the interface 207, the loop control unit 202 closes the line loop (DC loop) for the telephone line L under the control of the CPU 201 (step S3), and the subscriber telephone line network N The call activation for is completed.

The telephone number information of the slave station S read from the slave station number memory 103 is sent from the data processing section 1 to the line control section 2, and the CPU 201 of the line control section 2 sends the telephone number information.
After the call initiation control, the DTMF sending unit 205 is controlled to send a dial signal corresponding to the telephone number of the slave station S (step S4). At this point, the master station M is operating in the voice mode and the switching means of the mode switching unit 203 is in the direction shown in the figure. Therefore, the dial signal is transmitted through the mode switching unit 203 and the loop control unit 202 to the telephone line. Sent to L.

After sending the dial signal, C of the line control unit 2
The PU 201 monitors whether or not the called slave station S1 is busy and the response when it is not busy in steps S5 to S7.
That is, the timer 208 for response time monitoring is set, the polarity of the telephone line L is monitored through the loop control unit 202, and the tone signal receiving unit 206 monitors whether a busy tone is received. .

When the busy tone is not received by the timer 208 within the time limit and the reversal of the polarity of the telephone line L is detected, the CPU 201 determines that the called station S1 has responded, and the interface 207. The response information of the slave station S1 is transmitted to the CPU 101 of the data processing unit 1 via.

When the CPU 101 of the data processing unit 1 reads the response information, it controls the CPU 301 of the voice control unit 3 via the interface 304, and the message memory 3
Emergency information sending message is read from 02 and D / A
After being converted into a voice signal by the converter 303, the emergency information sending message is sent to the telephone line L (step S8).

After the message for sending emergency information is sent, the CPU 201 of the line controller 2 sets the timer 208 again (the timer 208 set for response monitoring is set).
Has been cleared by response detection or timer over. ), The reception of the mode switching signal from the called station S1 is monitored (steps S9 and S10).

When the called station S1 sends a mode switching signal (composed of a DTMF signal) within the time limit of the timer 208 and the tone signal receiving section 206 receives this, the CPU 201 receives the tone signal receiving section. 20
The reception information of the mode switching signal is read from 6 and the mode switching unit 203 is controlled to switch the mode of the master station M to the data mode (step S11). That is, the connection of the telephone line L is switched to the modem 204 side by the mode switching unit 203.

After the above control, the CPU of the line controller 2
201 transmits the conversion completion information to the data mode to the data processing unit 1, and when the CPU 101 of the data processing unit 1 reads the conversion completion information, it reads the emergency information stored in the emergency information memory 102 and the line The CPU 201 of the line control unit 2 sends it to the control unit 2 and sends the emergency information sent from the data processing unit 1 to the telephone line L via the modem 204, the mode switching unit 203 and the loop control unit 202 (step S12). ).

After sending the emergency information, the CPU 201 of the line control unit 2 sets the timer 208 again (the timer 208 set for monitoring the mode switching signal reception is cleared by the reception of the mode switching signal or the time-out). The reception confirmation data from the called station S1 is monitored (steps S13 and S14).

When the reception confirmation data is transmitted from the called station S1 within the time limit of the timer 208, the line control unit 2 receives the reception confirmation data to the CPU 201 via the modem 204 and the interface 207. The received reception confirmation data is transferred to the data processing unit 1. The CPU 101 of the data processing unit 1 records the transferred reception confirmation data in the reception confirmation data memory 104 and / or displays it on the display 5 via the display interface 107 (step S15).

As described above, the notification control of the emergency information to the slave station S1 is completed, but the data processing unit 1 sends the notification completion information indicating that the recording / display of the reception confirmation data is completed to the line control unit 2. In response to this, the CPU 201
Controls the loop control unit 202 to open the line loop formed for the telephone line L (step S16).
At the same time, the mode switching unit 203 is controlled to return the mode of the master station M to the voice mode (step S17) to prepare for a call to the next slave station S2.

Further, the CPU 101 of the data processing section 1
It is discriminated whether or not the slave station S which has transmitted the emergency information is the last in the calling order (K = n or not) (step S1).
8) In this case, since the mobile station S is the mobile station S1 (K = 1) having the highest calling order, the value obtained by adding 1 to the mobile station number K is set as the new mobile station number K ( In this case, K = 2.), The slave station with this slave station number K, in this case, the slave station S2 is designated as the next call destination (step S19).

When the next call destination is designated, the master station M repeats the notification control from steps S3 to S19, and when the notification control for the slave station S20 in the final order ends, the explanation given later. It is confirmed whether or not the slave station number is stored in the unreachable slave station memory 105 which becomes clear in step S2.
0), when not stored, all slave stations S1 to S2
Since the notification of emergency information to 0 has been completed,
The report control ends.

By the way, when the busy signal is received by the tone signal receiving section 206 after the dial signal of the called station S is sent, or when the polarity reversal of the telephone line L is not detected within the time limit by the timer 208 ( When the called slave station S is busy or does not respond), when the mode switching signal from the called slave station S is not received within the time limit time by the timer 208, or when the reception from the called slave station S is within the time limit time by the timer 208. When the confirmation data is not received, there is a case in which the emergency information cannot be sent to the called slave station S, or even if it is sent, it cannot be confirmed whether or not the called slave station S has received the emergency information. When the slave station) S occurs, the CPU 201 of the line control unit 2 sends to the data processing unit 1 information indicating that the slave station S currently performing notification control is an unreached slave station, Day When CPU101 processing unit 1 receives the information, after storing the slave station number K of the Yobuko station S at that time in the non Tatsuko station memory 105 (step S2
1) The control in steps S16 to S19 is performed to shift to the notification control for the next slave station S.

As described above, the notification control (sequential automatic call) for all the slave stations S1 to Sn is completed, and step S2 is performed.
When it is confirmed that the slave station number is stored in the unreachable slave station memory 105 at 0, the master station M starts the recalling control for the unreachable slave station S. The operation during the recalling control will be described below with reference to FIGS.

When the presence of the unreached slave station is confirmed in step S20, the CPU 101 of the data processing unit 1 adds 1 to the value N of the recalling counter 110 (step S10).
1), the slave station number of the frontmost slave station S stored in the unreached slave station memory 105 (the slave station number stored in the highest address)
P is designated (step S102), and steps S103-
In S117, steps S3 to S17 shown in FIG.
When the notification to the re-calling slave station S is completed (when the control proceeds to step S117), the CPU 101 of the data processing unit 1 determines that the slave station number P of the slave station S is , Check whether it is the last slave station number of the slave station numbers stored at that time (slave station number stored in the lowest address among the addresses storing slave station numbers). (Step S118) If it is not the last rank, the slave station number P is deleted from the unreached slave station memory 105 (Step S119), and then Step S120,
In step S121, the next slave station number stored in the unreachable slave station memory 105 is detected, the new slave station number P is set as the number, and the slave station S having the slave station number P is processed in step S1.
Control from 03 is advanced.

Further, when the called slave station S becomes an unreached slave station again for the re-call, the control proceeds to step S122, and in step S122 and step S123, the same as in steps S16 and S17. Then, the telephone line L is opened to switch the operation mode to the voice mode, and the slave station number P of the called slave station S is the last slave station number stored in the unreachable slave station memory 105 as in step S118. Is checked (step S124), and if it is not the last number, the corresponding slave station number P is set to the unreached slave station memory 105.
While holding the same (without performing the erasing process of step S119), the process proceeds to step S120, and the re-calling process of step S103 and subsequent steps is performed for the next unreached slave station.

If it is determined in step S118 that the slave station number P of the slave station S for which the notification control has been completed due to the re-call is the last number stored in the unreached slave station memory 105, the data is returned. CPU 10 of processing unit 1
1 deletes the slave station number P from the unreachable slave station memory 105 (step S125), and the unreachable slave station memory 105
Then, it is judged whether or not the storage of the slave station number remains (step S126), and if it does not remain, the recalling counter 110 is cleared (step S127), and the series of control ends.

Further, in step S124, it is determined that the slave station number P of the slave station S for which the notification control has not been completed even in the re-call is the last number stored in the unreachable slave station memory 105. Or step S1 above
When the storage of the slave station number in the unreachable slave station memory 105 remains at 26, it is possible to retry the call again to the slave station S of the slave station number stored in the unreachable slave station memory 105. However, here, the CPU 101 causes the recall call counter 110.
It is confirmed whether or not the value N of is the set value, that is, the value set as the number of times of re-calling attempts (step S1
28) When the value N is not the set value, 1 is added to the value N of the recalling counter 110 (step S101), and the control from step S102 is repeated.

As described above, the recall call is repeated,
When the control reaches step S128 with the value N of the recalling counter 110 reaching the set value, C of the data processing unit 1
The PU 101 displays the slave station number stored in the unreachable slave station memory 105 at that time as an unreachable slave station number on the display 5 via the display interface 107 and / or the printer 6 via the printer interface 108. Is printed out (step S129), a warning is displayed on the audible indicator 7 via the audio interface 109 (step S130), the recalling counter 110 is cleared (step S127), and a series of processing is completed.

As described above, the parent station M finds out the number of the child station which cannot send the emergency information or cannot confirm the completion of sending the emergency information even after the call is retried a prescribed number of times. Emergency information by another means can be considered for the slave station.

Next, the operation of the slave station S according to the embodiment will be described according to the processing flow shown in FIG.

In the slave station S, the ID memory 808 stores
The name of the person responsible for ensuring safety of the management office receiving the emergency information is registered in advance.

The slave station S constantly monitors the incoming call from the subscriber telephone line network N (step S201). When an incoming call occurs and a calling signal is sent to the telephone line L, the calling signal detects the incoming call. The incoming detection information is detected by the unit 806 and read by the CPU 801.

When the CPU 801 reads the incoming call detection information, it controls the audible sound emitting section 812 to audibly display the incoming call (step S202), and the operator of the child station S listens to the response operation (keyboard operation). When the response button in 809 is pressed or the handset 814 is picked up from the slave station S main body (telephone) (step S203), CP
The U 801 controls the loop controller 802 by pressing the response button on the keyboard 809 or operating a hook switch (not shown), and closes the line loop (DC loop) for the telephone line L to enter a state of responding. (Step S204).

The above operation is the same when receiving an incoming call from a general telephone. However, when the caller is the master station M, as described above, the master station M sends the response of the slave station S. After the detection, an emergency information report message is sent from the parent station M, so that it can be distinguished from an incoming call from a general telephone.

When the emergency information report message is sent from the master station M, the operation mode of the slave station S is the voice mode at this time, so the message is the loop control unit 802.
Sound is emitted from the handset 814 or the audible sound emitting unit 812 via the mode switching unit 803 and the call circuit unit 813 (step S205).

When the operator listens to this emergency information report message and performs a mode switching operation with the keyboard 809 (step S206), the CPU 801 reads the mode switching operation and controls the DTMF sending section 805 to generate a mode switching signal. The specified DTMF signal is sent to the telephone line L.
To the mode switching unit 8 (step S207).
03 is controlled to switch the operation mode to the data mode (step S208). That is, the telephone line L is switched and connected from the call circuit unit 813 side to the modem 804 side and the master station M is connected.
Be prepared to receive emergency information from.

As described above, the master station M sends the emergency information after automatically switching to the data mode by the upper mode switching signal, so that the CPU 801 receives the emergency information via the modem 804. Then (step S
209), it is recorded in the emergency information memory 807 and displayed on the display 810 (step S210).

The operator who confirms the emergency information displayed on the display 810 of the slave station S performs a reception confirmation operation by operating the keyboard 809 (step S211). The reception confirmation operation involves the operation of inputting the name of the operator, so that only the reception confirmation operation by the specific operator (safety officer) is effective, and the reliability of the transmission of emergency information is improved. Have secured.

When the reception confirmation operation performed by the keyboard 809 is read, the CPU 801 confirms that the input operator's name is the name registered in the ID memory 808, and calls the reception confirmation data via the modem 804. It is sent to the line L (step S212). The reception confirmation data includes at least the name of the person who confirmed the receipt of the emergency information obtained by collating the registered content of the ID memory 809 with the input name, and the receipt confirmation time obtained by the clock function 815 of the CPU 801.

Further, in order to make the reception confirmation operation easier, when the emergency information is received, the I
It is also possible to perform the reception confirmation operation by displaying the name of the receipt confirmation person registered in the D memory 808 and the display name on the display 810 and designating the displayed name by an index (cursor).

Further, when it is necessary to confirm whether or not the emergency information is surely transmitted to the person who should receive the emergency information (safety officer) (when the emergency information is extremely important)
For this purpose, the reception confirmation operation in the slave station S may require the input of the password of the receiver.

Further, the CPU 801 controls the sending of the receipt confirmation data and prints out the emergency information recorded in the emergency information memory 807 from the printer 811 by the receipt confirmation operation (step S213). After sending the data, the loop control unit 802 is controlled to open the line loop of the telephone line L to disconnect the line (step S214), the mode switching unit 803 is returned to the direction shown, and the slave station S is in the standby state. To prepare for the next incoming call.
