In the fifth aspect of the present invention, in any one of the first to fourth aspects, the IP telephone server device responds to each of the plurality of simultaneous notifications for each terminal that is the target of each simultaneous notification. Changed to output information that makes it possible to collectively determine whether or not it was determined as a terminal.

A sixth aspect of the present invention is that the IP telephone server device according to any one of the first to fifth aspects repeatedly makes the simultaneous notification within a predetermined execution period at a predetermined execution interval, and the execution period and the simultaneous notification are performed. At least one of the execution intervals is set according to the operation by the operator.

According to the first aspect, information that enables determination of whether or not a response has been made is output for each of two or more terminals among the plurality of terminals, so that the administrator can easily determine the safety based on the information. You can check. Therefore, it is possible to reduce the trouble of the administrator regarding the safety confirmation using the private telephone exchange system.

According to the second aspect, the alarm operation notifies that there is a terminal that has not been determined to have responded even after the waiting time has elapsed. Therefore, it is possible to reduce the trouble of the administrator regarding the safety confirmation using the private telephone exchange system.

According to the third aspect, since the information indicating the position of the terminal that has not been determined to have responded is output, the administrator can confirm the location position of the owner of the terminal that does not respond based on the information. .. As a result, it is possible to facilitate the action by the administrator when the terminal does not respond.

According to the fourth aspect, it is possible to confirm from the output data file whether or not it is determined that the device that received the data file has responded to each of the terminals that are the targets of the simultaneous report.

According to the fifth aspect, it is possible to collectively determine from the output information whether or not it is determined that a response has been made for each of the terminals that are the targets of each simultaneous report for each of the plurality of simultaneous reports. .. Therefore, it is possible to confirm the transition of whether or not it is determined that one terminal has responded to each of a plurality of simultaneous reports.

According to the sixth aspect, the simultaneous notification is repeatedly performed at a predetermined execution interval within a predetermined execution period. Therefore, it is not necessary for the administrator to manage the start of the simultaneous report. Further, at least one of the execution period and the execution interval is set according to the operation by the operator. Therefore, the administrator can arbitrarily set at least one of the execution period and the execution interval.

FIG. 2 is a block diagram showing a functional configuration of the IP telephone server device SV.
The IP telephone server device SV includes a control unit 1, a storage unit 2, a communication interface unit 3, an input / output interface unit 4, an input unit 5, a display unit 6, a ringing unit 7, and an external port 8.

The control unit 1 includes a computer configured by connecting a CPU (central processing unit), a ROM (read-only memory), and a RAM (random-access memory) by a system bus as basic hardware, and is stored in the ROM. Performs various types of information processing based on the operating system and application program.

The storage unit 2 stores various types of information necessary for the control unit 1 to perform various types of information processing. As the storage unit 2, for example, a well-known storage device such as an HDD (hard disk drive) or an SSD (solid state drive) that can be written and read at any time can be used.

Under the control of the control unit 1, the communication interface unit 3 is connected to the wireless terminals MT11, MT12, MT13, ..., MT21, MT22, MT23, ... And the fixed terminal (not shown) via the premises network NW. Voice data and control data are transmitted and received according to RTP (real-time transport protocol).
An input unit 5, a display unit 6, a ringing unit 7, and an external port 8 are connected to the input / output interface unit 4. The input / output interface unit 4 performs input / output processing for exchanging data between each of these connected units and the control unit 1.

The input unit 5 inputs data and instructions by an operation by the operator. As the input unit 5, a well-known input device such as a keyboard and a mouse can be used.
The display unit 6 displays various screens under the control of the control unit 1. As the display unit 6, a well-known display device such as a liquid crystal display can be used.
A touch panel can also be used as the input unit 5 and the display unit 6.

The ringing unit 7 performs a ringing operation for emitting an alarm sound. As the ringing unit 7, for example, a well-known device including a speaker and an audio signal output circuit can be used.
An external information device is connected to the external port 8 as needed. The external port 8 electrically connects the external device and the input / output interface unit 4. As the external port 8, for example, a well-known USB (universal serial bus) port can be used.

By the way, the control unit 1 realizes a function as an exchange control unit 11 and a function as a safety confirmation unit 12 by executing an application program.
The exchange control unit 11 performs a process for establishing a session by SIP (session initiation protocol) between terminals. Further, the exchange control unit 11 conforms to the DECT (digital enhanced telecommunications) method. The processing by the exchange control unit 11 may be the same processing as that performed by another existing IP telephone server device, for example.
The safety confirmation unit 12 performs the safety confirmation process and the safety output process, which will be described later.

A part of the storage area of the storage unit 2 is used as a terminal management information storage unit 21, a setting table 22, and a history information storage unit 23 for safety confirmation processing and safety output processing.

FIG. 3 is a diagram schematically showing an example of the stored contents of the terminal management information storage unit 21.
The terminal management information storage unit 21 stores the telephone numbers assigned to the wireless terminals MT11, MT12, MT13, ..., MT21, MT22, MT23, ..., Which are used for safety confirmation. Further, the terminal management information storage unit 21 stores the name of the worker who owns the wireless terminal MT to which the telephone number is assigned and the name of the group to which the worker belongs in association with the above telephone number.

FIG. 4 is a diagram schematically showing an example of the stored contents of the setting table 22.
The setting table 22 stores the setting values for each item of the confirmation interval, the waiting time, and the execution period. The confirmation interval is the interval from the completion of the safety determination once to the simultaneous notification for the next safety determination. The waiting time is the time to wait for a response to confirm the safety. The execution period is the period during which the process for confirming the safety is executed. In the example of FIG. 4, in the execution period from 9:00 to 17:00, 30 minutes after the previous safety judgment is completed, a new safety judgment is made all at once, and 60 minutes from the all-out notification. Until it elapses, it is set to wait for a response from an unanswered wireless terminal. The execution period may be determined to include the day of the week, the date, and the like. That is, the execution period may be set as, for example, "Monday to Friday 9:00 to 17:00". The execution period may also be defined as the time from some start timing to the end timing. That is, the execution period may be defined as, for example, "8 hours", and the execution period may be from the time when the start instruction is given by the operator to the time when 8 hours elapse.

FIG. 5 is a diagram schematically showing an example of the stored contents of the history information storage unit 23.
The history information storage unit 23 stores the determination result in one safety determination as one data record (hereinafter, referred to as a management record). One management record contains a start date and time, an end date and time, and a plurality of response flags in association with a number for identifying the management record. The start date and time represents the date and time when the safety judgment was started. The end date and time represents the date and time when the safety judgment was completed. The plurality of response flags are associated with each of the wireless terminals MT to be confirmed for safety. In the example of FIG. 5, six response flags corresponding to each of the six wireless terminal MTs whose telephone numbers are "10000", "10001", "10002", "10003", "10004", and "10005" are included. The response flag is 1-bit data, and the state in which the value is "1" is set as the set state, and indicates that the response has been completed.

(motion)
Next, the operation of the IP telephone server device SV configured as described above will be described. The operation of the IP phone server device SV for enabling a call between terminals may be the same as that of another existing IP phone server device. Therefore, the description thereof will be omitted. Then, in the following, the operation for confirming the safety will be described.

First, the change of the set value stored in the setting table 22 will be described.
When the operator requests a change in the setting related to the safety confirmation by the operation on the input unit 5, the safety confirmation unit 12 starts the setting change process.

FIG. 6 is a flowchart of the setting change process by the safety confirmation unit 12.
In step Sa1, the safety confirmation unit 12 causes the display unit 6 to display the setting screen.
FIG. 7 is a diagram showing an example of a setting screen.
The setting screen shown in FIG. 7 is an example in the case where the contents of the setting table 22 are in the state shown in FIG. The setting screen includes input fields 101, 102, 103 and an end button 104. The input fields 101, 102, and 103 are areas for inputting the setting values of the confirmation interval, the waiting time, and the execution period. The safety confirmation unit 12 displays the set values stored in the setting table 22 as shown in FIG. 7 on the setting screen displayed in step Sa1.
Thus, the operator can confirm the current setting values of the confirmation interval, the waiting time, and the execution period from the setting screen. Then, the operator operates the input unit 5 to select an input field in which the set value to be changed is displayed.

In step Sa2, the safety confirmation unit 12 confirms whether or not any of the input fields 101, 102, and 103 has been selected. Then, the safety confirmation unit 12 determines No and proceeds to step Sa3 until the input field is not selected as described above.
In step Sa3, the safety confirmation unit 12 confirms whether or not a new set value for the input item has been input. Then, the safety confirmation unit 12 determines No if such an input is not made, and proceeds to step Sa4.
In step Sa4, the safety confirmation unit 12 confirms whether or not the end button 104 has been operated. Then, the safety confirmation unit 12 determines No if the end button 104 has not been operated, and returns to step Sa2.
Thus, the safety confirmation unit 12 waits for any of the selection of the input field, the input of the set value, and the operation of the end button 104 in steps Sa2 to Sa4. Then, if one of the input fields 101, 102, and 103 is selected in this standby state, the safety confirmation unit 12 determines Yes in step Sa2 and proceeds to step Sa5.

In step Sa5, the safety confirmation unit 12 determines the item corresponding to the selected input field as an input item. After that, the safety confirmation unit 12 returns to the standby state of step Sa2-step Sa4.

After performing the operation of selecting any of the input fields 101, 102, and 103 as described above, the operator operates the input unit 5 to input the set value. Then, the safety confirmation unit 12 determines Yes in step Sa3, and proceeds to step Sa6.
In step Sa6, the safety confirmation unit 12 updates the set value stored in the setting table 22 with respect to the input item to the input set value described above.
In step Sa7, the safety confirmation unit 12 updates the setting screen so as to represent the contents of the updated setting table 22. After that, the safety confirmation unit 12 returns to the standby state of step Sa2-step Sa4. Thus, the safety confirmation unit 12 functions as a setting means for setting at least one of the execution period and the execution interval according to the operation by the operator.

When the operator completes the change of the set value, the operator operates the end button 104. Then, the safety confirmation unit 12 determines Yes in step Sa4 and ends the setting change process.

By the way, in many cases, the IP telephone server device SV is always in the operating state. When the IP telephone server device SV is started for the first time, or when the IP telephone server device SV is restarted after maintenance or the like is performed, the safety confirmation unit 12 starts the safety confirmation process. Then, the safety confirmation unit 12 continues to execute the safety confirmation process while the IP telephone server device SV continues to be in the normal operating state.

FIG. 8 is a flowchart of the safety confirmation process by the safety confirmation unit 12.
In step Sb1, the safety confirmation unit 12 confirms whether or not the safety confirmation is being executed. That is, the safety confirmation unit 12 confirms whether or not the current time is within the period represented by the set value of the execution period in the setting table 22. Then, the safety confirmation unit 12 determines No if it is not during the execution period, and proceeds to step Sb2.
In step Sb2, the safety confirmation unit 12 confirms whether or not the start instruction described later by the operator has been given. Then, the safety confirmation unit 12 determines No if the start instruction has not been given, and returns to step Sb1.
Thus, in step Sb1 and step Sb2, the safety confirmation unit 12 waits for the execution period or the start instruction to be given. Then, if the current time is within the period represented by the set value of the execution period in the setting table 22, the safety confirmation unit 12 determines Yes in step Sb1 and proceeds to step Sb3. If the start instruction is given, the safety confirmation unit 12 determines Yes in step Sb2 and proceeds to step Sb3.

In step Sb3, the safety confirmation unit 12 makes a simultaneous report. Specifically, the safety confirmation unit 12 instructs the exchange control unit 11 to make a simultaneous report using the DECT simultaneous report function using the telephone number stored in the terminal management information storage unit 21 as the report destination. In response to this instruction, the exchange control unit 11 makes a simultaneous report to the report destination instructed by the safety confirmation unit 12 according to a well-known procedure. As a result, the safety judgment will be newly started. Thus, the safety confirmation unit 12 functions as a reporting means for simultaneously reporting to two or more terminals among the plurality of terminals.
In step Sb4, the safety confirmation unit 12 adds a management record for managing the result of the safety determination this time to the history information storage unit 23.

FIG. 9 is a diagram schematically showing an example of the stored contents of the history information storage unit 23.
FIG. 9 shows an example after the management record is added as described above when the safety determination is started when the stored contents of the history information storage unit 23 are in the state shown in FIG.
The management record shown at the bottom of FIG. 9 is a newly added management record. As shown in FIG. 9, the safety confirmation unit 12 adds a management record in which the date and time when the simultaneous notification was made immediately before is included as the start date and time and all the response flags are in the reset state. The safety confirmation unit 12 sets the end date and time of the management record to be added to a predetermined null value.

In step Sb5, the safety confirmation unit 12 confirms whether or not a response has been made from any of the wireless terminals MT of the simultaneous notification destination. Then, the safety confirmation unit 12 determines No if no response is made from any of the wireless terminals MT, and proceeds to step Sb6.
In step Sb6, the safety confirmation unit 12 confirms whether or not the period of waiting for a response has expired. Then, when it cannot be determined that the period for waiting for the response has expired, the safety confirmation unit 12 determines No and returns to step Sb5.
Thus, in step Sb5 and step Sb6, the safety confirmation unit 12 waits for a response or the end of the waiting period.

A worker who possesses a wireless terminal MT that has received a simultaneous report uses the wireless terminal MT to make a transmission with a predetermined number for response. This transmission is notified to the IP telephone server device SV via the base station BS, the control device CS, and the premises network NW, accompanied by the notification of the telephone number of the wireless terminal MT as the caller ID. The notification is given to the exchange control unit 11 by the communication interface unit 3. When the exchange control unit 11 confirms that the transmission is made with a number predetermined for the above response, the exchange control unit 11 gives that fact and the caller ID to the safety confirmation unit 12. Then, the safety confirmation unit 12 determines Yes in step Sb5, and proceeds to step Sb7.

In step Sb7, the safety confirmation unit 12 sets the response flags included in the management record added in step Sb4 that are associated with the caller ID given by the exchange control unit 11 as described above. To do.
FIG. 10 is a diagram schematically showing an example of the stored contents of the history information storage unit 23.
In FIG. 10, when the stored contents of the history information storage unit 23 are in the state shown in FIG. 10, the safety confirmation unit 12 responds to the response from the wireless terminal MT whose telephone number is “1003”. An example after executing step Sb7 is shown. Therefore, in the management record shown at the bottom of FIG. 10, the response flag associated with the telephone number "1003" is set to "1". Thus, the safety confirmation unit 12 functions as a determination means for determining the terminals that have responded to the simultaneous notification.

In step Sb8, the safety confirmation unit 12 confirms whether or not there is an unanswered terminal. Specifically, the safety confirmation unit 12 confirms whether or not any of the response flags included in the management record added in step Sb4 is in the reset state. Then, the safety confirmation unit 12 determines Yes if the response flag in the reset state remains, returns to the standby state in steps Sb5 and Sb6, and prepares for a response from another wireless terminal MT. On the other hand, if all the response flags included in the management record added in step Sb4 are in the set state, the safety confirmation unit 12 determines No in step Sb8 and proceeds to step Sb9.
In step Sb9, the safety confirmation unit 12 writes the current date and time as the end date and time in the management record added in step Sb4. In this way, the safety confirmation unit 12 ends the safety determination when all the wireless terminals MT to be confirmed have responded.

On the other hand, the safety confirmation unit 12 determines Yes in step Sb6 if the timing for ending the standby period arrives before all the wireless terminals MT to be confirmed respond. Then, the process proceeds to step Sb10. The timing at which the waiting period should end is the timing at which the waiting time stored in the setting table 22 has elapsed since the simultaneous notification was made in step Sb3. The timing at which the waiting period should be terminated is also the timing at which the operator gives an termination instruction, which will be described later.
In step Sb10, the safety confirmation unit 12 writes the current date and time as the end date and time in the management record added in step Sb4. In this way, the safety confirmation unit 12 ends the safety determination when the standby period ends before all the wireless terminals MT to be confirmed have responded.

In step Sb11, the safety confirmation unit 12 confirms whether or not the alarm is permitted. Specifically, the safety confirmation unit 12 determines whether or not to allow the alarm based on the alarm flag set as described later according to the operation by the operator. Then, if the alarm is permitted, the safety confirmation unit 12 determines Yes and proceeds to step Sb12.

In step Sb12, the safety confirmation unit 12 starts an alarm operation. Specifically, the safety confirmation unit 12 instructs the ringing unit 7 to start ringing. In response to this instruction, the ringing unit 7 starts ringing a predetermined alarm sound. The alarm operation may be accompanied by another operation such as display of an alarm message on the display unit 6. In this way, the safety confirmation unit 12 cooperates with the ringing unit 7 to perform a predetermined alarm operation when there is a wireless terminal MT that does not respond even after a predetermined waiting time elapses after the simultaneous notification is made. It realizes the function as an alarm means to be performed.
In step Sb13, the safety confirmation unit 12 waits for the condition for stopping the alarm operation to be satisfied. When the elapsed time from the start of the alarm operation exceeds a predetermined time or the operator performs an operation instructing the stop of the alarm in the input unit 5, the safety confirmation unit 12 determines Yes and steps. Proceed to Sb14.
In step Sb14, the safety confirmation unit 12 stops the alarm operation. Specifically, the safety confirmation unit 12 instructs the ringing unit 7 to stop ringing. In response to this instruction, the ringing unit 7 stops ringing the alarm sound.

When the safety confirmation unit 12 finishes this step Sb14 or the above step Sb9, the safety confirmation unit 12 proceeds to step Sb15. If the safety confirmation unit 12 determines No in step Sb11 because the alarm is not permitted, the safety confirmation unit 12 passes step Sb12-step Sb14, that is, proceeds to step Sb15 as it is without performing an alarm operation. Proceed with.
In step Sb15, the safety confirmation unit 12 confirms whether or not the time stored as the execution interval in the setting table 22 has elapsed since the previous safety determination was completed. Then, the safety confirmation unit 12 determines No if the time has not elapsed, and proceeds to step Sb16.
In step Sb16, the safety confirmation unit 12 confirms whether or not the start instruction described later by the operator has been given. Then, the safety confirmation unit 12 determines No if the start instruction has not been given, and returns to step Sb15.
Thus, in step Sb15 and step Sb16, the safety confirmation unit 12 waits for the time determined as the execution interval of the safety determination to elapse after the previous safety determination is completed, or for the start instruction to be given. Then, if the current time is after the date and time indicated as the end date and time to the latest management record stored in the history information storage unit 23 and the time stored as the execution interval is added to the safety confirmation unit 12. It is determined as Yes in step Sb15, and the process returns to step Sb3. If the start instruction is given, the safety confirmation unit 12 determines Yes in step Sb16 and returns to step Sb3. Then, the safety confirmation unit 12 repeats the processes after step Sb3 in the same manner as described above. That is, the safety confirmation unit 12 makes a new safety determination. That is, the safety confirmation unit 12 repeatedly executes the safety determination every time the time determined as the execution interval elapses after the previous safety determination is completed, or every time the operator instructs the start.

When the safety confirmation unit 12 is requested to confirm the result of the safety determination by the operation by the operator in the input unit 5, the safety confirmation unit 12 executes the safety output process by a thread different from the above-mentioned safety confirmation process.
11, 12 and 13 are flowcharts of safety output processing by the safety confirmation unit 12.

In step Sc1 of FIG. 11, the safety confirmation unit 12 causes the display unit 6 to display the response status screen. Specifically, the safety confirmation unit 12 generates image data representing the response status screen, and instructs the display unit 6 to display the screen based on the image data. In response to this instruction, the display unit 6 displays the response status screen.
FIG. 14 is a diagram showing an example of a response status screen.
The response status screen shown in FIG. 14 is an example in the case where the stored contents of the history information storage unit 23 are in the state shown in FIG. Since the end date and time of the latest management record shown in FIG. 5 is not a null value, the safety confirmation unit 12 is in the standby state of steps Sb15 and Sb16 in the safety confirmation process, and the safety determination is not performed. That is, the response status screen shown in FIG. 14 is an example of what is displayed in a state where the safety determination has not been performed.
The response status screen includes a response status list 201, a group name display field 202, a position confirmation button 203, a file button 204, a start button 205, an end button 206, and an alarm setting switch 207.

The response status list 201 shows the status of the response flags included in the three management records from the newest one stored in the history information storage unit 23. The group name display field 202 displays the name of the group selected as the display target. The position confirmation button 203 is operated to request to present the current position of the wireless terminal MT which has not been responded by the latest response determination. The file button 204 is operated by the operator to request that a data file representing the result of the position confirmation be output to the outside. The start button 205 is operated by the operator to request that the safety determination be started. The end button 206 is operated by the operator to request that the safety determination be completed. The alarm setting switch 207 is operated by the operator to set whether or not to allow the alarm.
Thus, the response status screen is an example of information that makes it possible to determine whether or not a response has been made, and the safety confirmation unit 12 serves as an output means for outputting such information in cooperation with the display unit 6. The function of is realized.

In FIG. 14, the response status list 201 shows the status of the response flag in each of the area representing the worker name and the other matrix-like areas indicated as "previous time", "previous time", and "current". The display state of each area is different depending on whether or not the corresponding response flag is in the set state. The display state is changed by changing, for example, the ground color or the character color. However, in FIG. 14, the difference in the display state is shown by hatching for convenience. The response flag corresponding to the area indicated by hatching is in the reset state, indicating that no response was made. That is, in the response status list 201, in the latest safety determination indicated as "current", the worker D possessing the wireless terminal MT having the telephone number "1003" and the wireless terminal MT having the telephone number "10005" It is shown that there was no response from the worker F who possesses.
Further, in FIG. 14, the alarm setting switch 207 shows a state in which an alarm is permitted.
The character string "stopped" displayed between the start button 205 and the end button 206 indicates that the safety determination has not been performed. When the end date and time of the latest management record is not a null value as shown in FIG. 5, the safety confirmation unit 12 displays such a display.

In step Sc2, the safety confirmation unit 12 confirms whether or not the execution status of the safety determination in the safety confirmation process has changed. Then, the safety confirmation unit 12 determines No if the execution status has not changed, and proceeds to step Sc3.

In step Sc21, the safety confirmation unit 12 confirms whether or not there is an unanswered wireless terminal MT. Specifically, the safety confirmation unit 12 confirms whether or not any of the response flags included in the latest management record is in the reset state. Then, the safety confirmation unit 12 determines Yes if there is an unanswered wireless terminal MT, and proceeds to step Sc22.

In step Sc22, the safety confirmation unit 12 determines the position of the unanswered wireless terminal MT. This can be realized, for example, by acquiring the location registration information managed by the control device CS. Thus, the safety confirmation unit 12 functions as a position determining means for determining the position of the wireless terminal MT.
In step Sc23, the safety confirmation unit 12 causes the display unit 6 to display the position display screen. Specifically, the safety confirmation unit 12 generates image data representing the position display screen, and instructs the display unit 6 to display the screen based on the image data. In response to this instruction, the display unit 6 displays the position display screen.

FIG. 16 is a diagram showing an example of a position display screen.
The position display screen shown in FIG. 16 includes a position list 301 showing the position of the unanswered wireless terminal MT and a back button 302. That is, the position display screen is an example of information indicating the position determined for the wireless terminal MT, and the safety confirmation unit 12 realizes a function as an output means for outputting such information in cooperation with the display unit 6. doing.
In step Sc24, the safety confirmation unit 12 waits for the return button 302 to be operated.

On the other hand, if there is no unanswered wireless terminal, the safety confirmation unit 12 determines No in step Sc21 and proceeds to step Sc25.
In step Sc25, the safety confirmation unit 12 causes the display unit 6 to display the non-target screen. Specifically, the safety confirmation unit 12 generates image data representing a non-target screen, and instructs the display unit 6 to display a screen based on the image data. In response to this instruction, the display unit 6 displays a non-target screen. The targetless screen is a screen for notifying the operator by, for example, a character message, that there is no unanswered wireless terminal MT. The untargeted screen also includes a back button.
In step Sc26, the safety confirmation unit 12 waits for the return button 302 to be operated.

When the operator finishes confirming the position of the unanswered wireless terminal MT from the position list 301, the operator operates the back button 302. If the operator confirms that there is no unanswered wireless terminal on the non-target screen, the operator operates the back button on the non-target screen. As a result, the safety confirmation unit 12 determines Yes in step Sc24 or step Sc26, and returns to the standby state of step Sc2-step Sc9 in FIG.

The operator operates the file button 204 when he / she wants to output a data file showing the result of the safety determination to the outside. Then, the safety confirmation unit 12 determines Yes in step Sc9, and proceeds to step Sc31 in FIG.
In step Sc31, the safety confirmation unit 12 causes the display unit 6 to display the file selection screen. Specifically, the safety confirmation unit 12 generates image data representing the file selection screen, and instructs the display unit 6 to display the screen based on the image data. In response to this instruction, the display unit 6 displays the file selection screen.

FIG. 17 is a diagram showing an example of a file selection screen.
The file selection screen shown in FIG. 17 includes a list 401 of management records, a plurality of output buttons 402, and a back button 403.
Listing 401 shows a combination of a start date and time and an end date and time included in the management record stored in the history information storage unit 23. The plurality of output buttons 402 are associated with the combination of the start date and time and the end date and time shown in Listing 401, respectively.

In step Sc32, the safety confirmation unit 12 confirms whether or not the output button 402 has been operated. Then, the safety confirmation unit 12 determines No if the output button 402 is not operated, and proceeds to step Sc33.
In step Sc33, the safety confirmation unit 12 confirms whether or not the back button 403 has been operated. Then, the safety confirmation unit 12 determines No if the return button 403 is not operated, and returns to step Sc32.
Thus, in step Sc32 and step Sc33, the safety confirmation unit 12 waits for either one of the output buttons 402 or the return button 403 to be operated.

The operator selects a combination of the start date and time and the end date and time representing the period during which the safety determination for which the result is desired to be output is performed from the list 401, and operates the output button 402 associated with the combination. Then, the safety confirmation unit 12 determines Yes in step Sc32, and proceeds to step Sc34.
In step Sc34, the safety confirmation unit 12 outputs a data file including the management record associated with the operated output button 402 from the external port 8 to an external device (not shown) connected to the external port 8. After that, the safety confirmation unit 12 returns to the standby state of step Sc32 and step Sc33. The form in which the management record is included in the data file is arbitrary, and may be determined by the designer or operator of the IP telephone server device SV. Further, the data file may be output to an arbitrary communication terminal by communication via the premises network NW. Since the data file contains a management record, it is an example of information that makes it possible to determine whether or not a response has been made, and the safety confirmation unit 12 cooperates with the input / output interface unit 4 to obtain such information. It realizes the function as an output means to output.

When the operator finishes outputting the necessary data file, he / she operates the back button 403. Then, the safety confirmation unit 12 determines Yes in step Sc33, and returns to the standby state of step Sc2-step Sc9 in FIG.

(effect)
As described above, the IP telephone server device SV displays a response status screen as shown in FIGS. 14 and 15 or outputs to an external device as a data file whether or not a response to the simultaneous report has been made. As described above, if the worker who is the target of the safety confirmation is made to possess the wireless terminal MT and the worker is required to perform the predetermined operation for the above response to the simultaneous report, the response is made. The status screen or data file represents the safety of the worker. Therefore, the administrator can confirm the safety of each worker only by checking the response status screen or the data file, and the time and effort of the administrator regarding the safety confirmation is reduced as compared with the conventional case.

Further, the IP telephone server device SV performs an alarm operation such as ringing in the ringing unit 7 when there is a wireless terminal MT whose response cannot be confirmed even after the waiting time has elapsed. Therefore, it is possible to make the administrator who does not frequently check the response status screen or the data file recognize that there is a wireless terminal that does not respond, that is, there is an operator who cannot confirm that it is safe. This makes it possible for the manager to promptly take measures such as safety confirmation by other means or relief activities. The IP telephone server device SV can also prevent the above alarm operation from being performed in response to an operation by the operator. Thereby, for example, in an environment where it is not preferable that the alarm operation is performed, or in a situation where the administrator does not need the alarm operation, the alarm operation can be stopped.

Further, the IP telephone server device SV displays a position display screen showing the position of the unanswered wireless terminal MT. By checking this position display screen, the administrator can easily recognize the place where there is a high possibility that there is a worker who cannot confirm that it is safe. Then, the manager can quickly go to the place to confirm the safety or take measures such as relief activities.

Further, the IP telephone server device SV outputs a data file to an external device as described above. Therefore, the safety can be managed by an external device.

Further, the IP telephone server device SV displays a list of the results of a plurality of safety determinations on the response status screens as shown in FIGS. 14 and 15. Therefore, based on this response status screen, the administrator can make, for example, a safety judgment in consideration of the results of a plurality of safety judgments. For example, a response may not be made from the wireless terminal MT possessed by the worker because the worker is performing work such that the response operation cannot be performed. In such an environment, it may not be preferable to take the above measures based on the result of one safety determination. However, it may be possible to reduce the burden on the administrator regarding the treatment by determining whether the above-mentioned treatment is really necessary in consideration of the results of the safety judgments of a plurality of times. In addition, the above-mentioned measures may be taken in consideration of both the result of such a plurality of safety determinations and the position information on the position display screen.

Further, the IP telephone server device SV repeatedly starts the safety determination at a predetermined execution interval within a predetermined execution period. Therefore, the time and effort of the administrator involved in the instruction to start the safety judgment is reduced. In addition, the simultaneous notification is not made until the period when the safety confirmation is unnecessary, such as outside the working hours, and the burden on the worker who owns the wireless terminal MT is reduced.

Further, although the IP telephone server device SV repeatedly starts the safety determination at a predetermined execution interval, the safety determination is also started in response to the start instruction by the operator. Therefore, if the administrator wants to start the safety judgment immediately for some reason, the administrator may give a start instruction.

Further, the IP telephone server device SV ends the safety determination in response to the termination instruction of the operator during the safety determination. Therefore, for example, when the administrator knows that there is no response from the unresponsive wireless terminal MT, the safety determination can be terminated, which enables flexible operation.

Further, the IP telephone server device SV sets the execution period and the execution interval according to the operation by the operator. Therefore, the manager can flexibly set the implementation status of the safety determination in consideration of the work schedule of the worker and the like. The IP telephone server device SV further sets the waiting time according to the operation by the operator. Therefore, the administrator flexibly sets the implementation status of the safety judgment in consideration of the influence of the burden on the worker involved in the response operation on the original work and the urgency of the action when there is a possibility that it is not safe. it can.
