PROBLEM TO BE SOLVED: To improve the convenience of a safety message control system.SOLUTION: A TTS (text to speech) server unit 18 converts input safety message text information into a safety message voice file. A media server unit 17 transmits the playback data on the safety message voice file through a telephone network, to a voice telephone terminal 4. When the use of the telephone network is disabled, the media server unit 17 retransmits a voice safety message to the voice telephone terminal 4 in each constant time. In the case of transmission of the reproduced data on the safety message voice file to the voice telephone terminal 4 fails even if voice calling is made for the maximum number of times, distribution is made to at least a public screen 5 in the identical area.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a technique for controlling a safety message.

  When a disaster such as an earthquake or an eruption occurs, a voice safety message control system can be used to contact the victims and non-stricken persons and to confirm the safety of the victims (Non-patent Document 1). The safety message control system is similar to the text safety message control system described later, but when a message registrant registers a message using a telephone number as a key, the message is stored for a certain period. On the other hand, the message receiver accesses the safety message control system using the telephone number as a key to confirm the stored message of the message registrant.

  In recent years, the text message safety message control system is being widely recognized due to the widespread use of smartphone terminals that allow easy text input (Non-patent Document 2). Since text information requires less data transfer than voice information, the possibility of squeezing the network bandwidth is reduced, and safety information can be quickly deployed.

  However, when registering or confirming a text message, a predetermined operation is required on the message terminal. For example, a registration operation for distributing a registered text message by electronic mail, an operation for opening the distributed electronic mail, and the like can be considered. For this reason, there is a problem that the safety message control system is not easy to use for those who are not good at operating the terminal and who have only terminals (mainly fixed telephones) that cannot display text messages.

  Therefore, it may be possible to use the above-described voice safety message control system. However, when a disaster occurs, it is easy for congestion to occur in the telephone network in the affected area, so it is not possible to confirm the voice message at a desired timing. Moreover, since the voice message is accumulated in the safety message control system for a certain period as described above, the data of the voice file related to the voice message becomes enormous.

  The present invention has been made in view of the above circumstances, and an object thereof is to improve the convenience of the safety message control system.

  In order to solve the above problems, the safety message control system according to claim 1 stores storage means for storing the safety message of the input text, and converts the safety message of the text into a voice safety message and stores the message. The gist of the present invention is to include conversion means stored in the means and transmission means for transmitting the voice safety message to the voice telephone terminal via the telephone network.

  The safety message control system according to claim 2 is the safety message control system according to claim 1, wherein, when the telephone network is not available, the transmitting means transmits the safety message of the voice at regular intervals. The gist is to re-send to the telephone terminal.

  The safety message control system according to claim 3 is the safety message control system according to claim 1 or 2, wherein the safety messages in the text are grouped and held for each user area, and at least public in the same area. The gist of the present invention is to further include a distribution means for distributing to a display medium.

  The safety message control system according to claim 4 is the safety message control system according to claim 3, wherein the distribution means transmits the voice safety message to the voice telephone terminal even if the transmission process is performed a maximum number of times. The gist is to perform the distribution process when transmission is not possible.

  The safety message control system according to claim 5 is the safety message control system according to any one of claims 1 to 4, wherein the voice safety message is transmitted after the voice safety message is transmitted to the voice telephone terminal. The gist of the invention is to further include deletion means for deleting from the storage means.

  The safety message control method according to claim 6 is a safety message control method performed by a safety message control system, wherein the safety message control system stores a safety message of an input text in a storage means, and the text A conversion step of converting the safety message of the voice into a voice safety message and storing it in the storage means; and a transmission step of transmitting the voice safety message to the voice telephone terminal via the telephone network. .

  The safety message control method according to claim 7 is the safety message control method according to claim 6, wherein in the transmission step, when the telephone network is unavailable, the safety message of the voice is sent to the voice at regular intervals. The gist is to re-send to the telephone terminal.

  According to the present invention, the convenience of the safety message control system can be improved.

It is a figure which shows the structure of a safety message control system. It is a figure which shows the audio | voice push notification process of safety message text information. It is a figure which shows the voice push notification process (at the time of congestion) of safety message text information. It is a figure which shows the example of an incomplete safety information list file. It is a figure which shows the delivery process of safety message text information. It is a reference figure at the time of explaining the effect of the present invention.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a safety message control system 1 according to the present embodiment. The safety message control system 1 includes a distribution function unit 11, a Web server unit 12, an AP server unit 13, a DB server unit 14, as functional units for registering safety message text information input in text. And a storage unit 15. Safety message text information input as text from the Internet terminal 2 is accumulated in the storage unit 15 via the function units 11 to 14. The storage unit 15 is accessible from all the functional units constituting the safety message control system 1.

  The safety message control system 1 includes a platform unit 16, a media server unit 17, a TTS (Text To Speech) server unit 18, and a mail server unit 19 as functional units for providing the accumulated safety message text information. And a distribution server unit 20.

  Here, the mail server unit 19 is a functional unit that the safety message control system 1 has conventionally provided. The mail server unit 19 is configured to transmit safety message text information, which is a text message, by electronic mail. That is, the conventional safety message control system 1 is configured such that the storage unit via the platform unit 16 from the AP server unit 13 based on an operation on the Internet terminal 3 that can be connected to the Internet, such as a smartphone terminal, as described above. 15, the safety message text information was taken out and a push notification was sent from the mail server unit 19.

  However, since the Internet terminal 3 which is a text terminal requires a predetermined operation as proposed above, only those who are not good at operating the Internet terminal 3 and only non-Internet terminals (mainly fixed telephones) It is not easy to use for those who have. Therefore, in the present invention, a safety message is transmitted by voice to the voice telephone terminal 4 which is a voice terminal. Thereby, the safety message control system 1 that is easy to use for all people is realized.

  Therefore, in this embodiment, in order to notify the voice message to the voice telephone terminal 4 which is a non-Internet terminal by voice, the media server unit 17 for sending a guidance to the voice message to the safety message control system 1 and the text information as voice. And a TTS server unit 18 for converting into a file. Based on an instruction from the AP server unit 13, the safety message text information acquired from the storage unit 15 by the platform unit 16 is converted into a safety message voice file by the TTS server unit 18, and a telephone network such as SIP / RTP is transmitted from the media server unit 17. The safety message is pushed and notified to the voice telephone terminal 4 via voice. The text-to-speech conversion process performed by the TTS server unit 18 is realized using existing technology.

  Further, as described in the above problem, push notification from the media server unit 17 to the voice telephone terminal 4 is highly likely to be incomplete due to congestion in the telephone network that accommodates the voice telephone terminal 4. Therefore, in this embodiment, two methods are proposed in order to reliably transmit the safety message. The first is to re-execute the push notification of the safety message voice file after a certain time has elapsed. Second, a distribution server unit 20 is provided that distributes the safety message text information before conversion to a display medium that can be used by an unspecified number. Based on an instruction from the platform unit 16, the distribution server unit 20 displays the safety message text information on the public screen 5 of the local government to which the voice telephone terminal 4 belongs based on the list of voice telephone terminals 4 that have not been completed. Push notifications.

  Next, a processing operation for notifying safety message text information by voice will be described with reference to FIG.

  First, after registering the safety message text information, based on the voice notification request in the Internet terminal 2, the AP server unit 13 notifies the voice message terminal 4 of the telephone number specified by the message registrant by voice of the safety message text information. Therefore, a safety message text information reproduction request is transmitted to the platform unit 16 (step S101).

  Next, when receiving the safety message text information reproduction request, the platform unit 16 transmits a safety message text information acquisition request to the storage unit 15 (step S102), and the safety message text information for the corresponding voice telephone terminal 4 is transmitted. Obtain (step S103).

  Subsequently, in order to convert the acquired safety message text information into voice, the platform unit 16 transmits a voice conversion request for the safety message text information to the TTS server unit 18 (step S104).

  The TTS server unit 18 converts the safety message text information into a safety message voice file based on the voice conversion request (step S105), and transmits a voice conversion result notification of the safety message text information to the platform unit 16 (step S105). S106), a safety message voice file deployment signal for storing the converted safety message voice file is transmitted to the storage unit 15 (step S107). As a result, the safety message voice file is accumulated in the storage unit 15.

  Thereafter, when receiving the voice conversion result notification of the safety message text information from the TTS server unit 18, the platform unit 16 transmits a playback request response to the AP server unit 13 that is the transmission source of the safety message text information playback request ( In step S108, a guidance reproduction request for reproducing the safety message voice file having received the voice conversion result on the corresponding voice telephone terminal 4 is transmitted to the media server unit 17 (step S109).

  Subsequently, the media server unit 17 transmits a safety message voice file acquisition request to the storage unit 15 based on the guidance reproduction request (step S110), and acquires the corresponding safety message voice file (step S111). Thereafter, a voice call is made to the corresponding voice telephone terminal 4 via the telephone network 6, the guidance message of the safety message and the reproduction data of the safety message voice file are transmitted to the voice telephone terminal 4, and the safety message is registered in the message. The person's family and relatives are notified (step S112).

  After the normal completion of the safety message reproduction, the media server unit 17 transmits a guidance reproduction result notification indicating that the guidance has been normally completed to the platform unit 16 (step S113). Thereafter, the platform unit 16 transmits a playback completion notification indicating that the audio message text information has been played back to the AP server unit 13 (step S114), and the safety message for deleting the corresponding safety message audio file. An audio file deletion request is transmitted to the storage unit 15 (step S115). The storage unit 15 deletes the corresponding safety message voice file based on the safety message voice file deletion request (step S116).

  As described above, the TTS server unit 18 converts the safety message text information into the safety message voice file, and the media server unit 17 transmits the reproduction data of the safety message voice file via the telephone network 6 to the voice telephone terminal 4. Therefore, it is possible to provide a safety message control system 1 that is easy to use for everyone because a text safety message can be confirmed even with a conventional landline telephone having no mail function or browser function.

  Further, since the platform unit 16 deletes the safety message audio file from the storage unit 15 after the normal end of the push notification of the safety message audio file, the storage resource capacity of the safety message control system 1 can be optimized. .

  Next, referring to FIG. 3, the processing operation when the voice call fails due to congestion in the telephone network will be described. Steps S201 to S212 are the same as steps S101 to S112.

  When congestion or the like occurs, a SIP response code: 503 (Service Unavailable) response is notified from the telephone network 6 to the media server unit 17 which is the voice caller (step S213).

  In that case, the media server unit 17 transmits a guidance reproduction NG (503 response) indicating that the guidance guidance notification by voice has failed to the platform unit 16 (step S214).

  When the platform unit 16 receives the guidance reproduction NG (503 response), the platform unit 16 activates a waiting timer as an incomplete management process, and waits for a process until a predetermined time set in the waiting timer elapses (step S215). Then, after the waiting timer times out, the same guidance reproduction request as that in step S209 is retransmitted to the media server unit 17 (step S216). Note that the value of the waiting timer can be arbitrarily set. However, considering the time until the congestion state of the telephone network 6 is resolved, for example, about 1 hour is preferable.

  Thereafter, the media server unit 17 re-executes the voice call to the voice telephone terminal 4 using the acquired safety message voice file (step S217). When the congestion state of the telephone network 6 is released and a new call can be accepted, the call from the media server unit 17 is accepted, and the safety message guidance guidance and the safety message voice file are stored. The reproduction data is transmitted to the voice telephone terminal 4 and the safety message is notified by voice. Then, after the normal completion of the safety message reproduction, the same processing as steps S113 to S116 is executed (steps S218 to S221). On the other hand, if the congestion state of the telephone network 6 has not been released, steps S214 to S217 are repeatedly executed at regular intervals of the waiting timer.

  As described above, since the media server unit 17 re-executes the voice call at regular intervals when the voice call fails due to congestion in the telephone network 6, the safety information can be reliably transmitted. .

  So far, the example in which the reproduction process of the safety message voice file is completed has been described. However, if the telephone network 6 cannot be used for a long time, the safety information cannot be transmitted even if the re-call is repeated several times, and the voice call may eventually be incomplete. Therefore, for example, when the maximum number of re-calls is 10 and the value of the waiting timer is 1 hour, the safety information cannot be confirmed even if it exceeds 10 hours.

  Therefore, if the safety message text information of the voice call that was not completed is listed and registered in the incomplete safety information list file, and the number of voice calls is unsuccessful at the maximum number of re-calls, The incomplete safety information list file is distributed to a public display medium. For example, as shown in FIG. 4, the incomplete safety information list files of Group A and B are generated for each region using telephone numbers as keys, and the telephone numbers, names and messages of message registrants and message recipients are generated. Contents etc. are registered and delivered to public display media when the voice notification reaches the maximum number of times. The method for generating the incomplete safety information file is arbitrary. For example, in consideration of being displayed for an unspecified number, the last three digits of the telephone number may be hidden, or a plurality of message names may be associated with one telephone number.

  The processing operation when the telephone network unusable state continues will be described with reference to FIG. Here, an example will be described in which the voice notification of the safety message to the voice telephone terminal is given up and the safety message is displayed in text on a public screen (for example, digital signage).

  After the number of voice calls exceeds the maximum number, the AP server unit 13 transmits an incomplete safety information delivery request to the platform unit 16 in order to deliver safety information related to the corresponding incomplete voice call (step S301).

  When receiving the incomplete safety information distribution request, the platform unit 16 transmits the incomplete safety information distribution request to the distribution server unit 20 as a new request (step S302).

  When the distribution server unit 20 receives the incomplete safety information distribution request, the distribution server unit 20 transmits a read request for the incomplete safety information list file to the storage unit 15 (step S303), and stores the incomplete safety information list files of Group A and B. Each is acquired (step S304).

  Thereafter, the distribution server unit 20 distributes the incomplete safety information list file of Group A to the public screen 5A of Group A (step S305), and distributes the incomplete safety information list file of Group B to the public screen 5B of Group B (step S305). S306). Thus, the contents of the incomplete safety information list files of Group A and B are displayed on the public screens 5A and 5B of Group A and B, respectively. When the person or an acquaintance views the display contents of the public screens A and B, the safety information of the message registrant can be confirmed. The delivery method of the incomplete safety information list file is arbitrary. For example, when the areas of Group A and B are close, both incomplete safety information list files of Group A and B may be distributed to the public screen 5A of Group A.

  After the distribution of the incomplete safety information list file is completed, the distribution server unit 20 transmits an incomplete safety information distribution completion response to the platform unit 16 and replies that the incomplete safety information distribution request has been normally completed (step S307). . Similarly, the platform unit 16 transmits an incomplete safety information distribution completion response to the AP server unit 13 and replies that the incomplete safety information distribution request has been normally completed (step S308). Regardless of whether or not the voice call process is incomplete, the voice call terminal 4 may be executed together with the reproduction process of the safety message voice file.

  As described above, the distribution server unit 20 holds the safety message text information related to unsuccessful voice calls in groups for each user's region, and the safety message voice even if the voice call is made the maximum number of times. When the reproduction data of the file cannot be transmitted to the voice telephone terminal 4, it is delivered at least to the public screen 5 in the same area, so that the safety information can be transmitted more reliably.

  The distribution process of the safety message text information may be executed in parallel with the reproduction process of the safety message voice file regardless of whether the voice call process is incomplete or not. Thereby, since the voice output of the safety information by the voice telephone terminal 4 and the text output of the safety information by the public screen 5 are simultaneously performed, the safety information can be transmitted more reliably.

  Finally, the effect of the present invention will be described with reference to FIG. According to the present invention, in the safety message control system 1, the safety message text information input from the Internet terminal 2 is converted into a safety message voice file, and push notification is made by voice to the voice telephone terminal 4 via the telephone network 6. It is possible to provide an easy-to-use safety message system for everyone, including elderly people, people with disabilities, and people who have only landlines.

  If the call cannot be connected due to congestion or the like, the voice push notification is re-executed every predetermined time. If the call is not connected, the safety message text information is distributed to the public screens 5A and 5B for each area. As a result, the opportunity for notifications can be expanded and safety information can be provided reliably.

  The safety message control system 1 described above can be realized by a computer having a calculation function such as a CPU and a storage function such as a memory. It is also possible to create a program for causing a computer to function as the safety message control system 1 and a storage medium for the program.
