Description

  The present invention relates to an information distribution apparatus having a function of distributing disaster information to an unspecified number of people when a disaster occurs, for example.

  When disasters occur due to earthquakes, torrential rains, etc., it is necessary to transmit information regarding the occurrence status and evacuation to many people quickly and without delay, and a disaster prevention radio system has been established for this purpose. The disaster prevention administrative radio system is configured as follows, for example. That is, a plurality of disaster prevention radio base stations and a plurality of audio broadcasting receivers capable of wireless communication between these base stations are distributed in the area, and each disaster prevention radio base station is disaster-reduced via a transmission line. The control station is connected to the disaster prevention center through a transmission line. When a disaster such as an earthquake occurs, disaster information is generated in the disaster prevention center, and this information is transmitted to each disaster prevention radio base station via the disaster prevention control station, and is wirelessly transmitted from these base stations. This radio-transmitted disaster information is received by an audio broadcast receiver, and is sent to the unspecified number of people (residents and passers-by) in the area from the outdoor speakers connected to the audio broadcast receiver by voice or siren. The information content is announced loudly.

  However, such a conventional disaster prevention administrative radio system transmits disaster information from each disaster prevention radio base station to each audio broadcasting receiver using a single dedicated radio network. For this reason, when a failure occurs in the dedicated wireless network due to the disaster, the disaster information is not transmitted from the disaster prevention radio base station to the audio broadcasting receiver, and as a result, the disaster information may not be distributed to local people. is there.

  On the other hand, in order to distribute disaster information to individuals in locations where it is difficult to receive voices that are loudly broadcast from the audio broadcasting receiver, the disaster information is transmitted via a public mobile communication network using a portable wireless terminal owned by the individual. A system for transmitting to the portable wireless terminal has been proposed (see, for example, Patent Document 1). If this system is used, it is possible to distribute disaster information to individuals even when a failure occurs in the dedicated wireless network of the disaster prevention administrative radio system.

  However, in this system, disaster information cannot be distributed to a person who does not have a portable wireless terminal or a person who does not have a portable wireless terminal turned on. In addition, since disaster information is basically distributed to specific individuals, considering the congestion of public mobile communication networks at the time of disaster, it is currently possible to distribute disaster information to a large number of unspecified people at the same time. It is difficult. That is, this system is merely an auxiliary means of audio broadcasting by an audio broadcasting receiver, and does not carry out broadcast distribution of disaster information to an unspecified number of people.

JP 2001-36645 A

  As described above, in the conventional disaster prevention administrative radio system, when a failure occurs in the dedicated radio network between the disaster prevention radio base station and the audio broadcasting receiver, disaster information is transmitted from the disaster prevention radio base station to the audio broadcasting receiver. As a result, disaster information cannot be distributed to local people. In addition, in a system that distributes disaster information using a portable wireless terminal possessed by an individual, it is difficult to broadcast the disaster information to an unspecified number of people.

If and means for output the audio signal, when generating the transmission information, including in response to an input of the distribution request, and a message indicating that requesting delivery, and identification information corresponding to the audio file to be distributed Transmission information is generated.
With such a configuration, the information distribution device only needs to transmit the identification information of the audio file to the slave station, and it is not necessary to transmit the audio file itself. It becomes possible to suppress an increase in traffic.

In the second configuration, the plurality of slave stations correspond to the identification information of the first audio file that represents the type of distribution information by chime or siren and the second audio file that represents the content of distribution information by an audio message. Means for storing each of them, and selectively reading out the stored first and second audio files according to the identification information, and a chime or siren represented by the read-out audio file, and an audio message signal If and means for exiting force and in generating the transmission information in response to the input of the distribution request, and a message indicating that requesting delivery, corresponding to the first audio file indicating the type of distribution information Transmission information including identification information and identification information corresponding to the second audio file representing the contents of the distribution information is generated.
If comprised in this way, it will become possible to alert | report not only the content of delivery information but the kind of delivery information with a chime or a siren, and it will become easy to recognize the kind of delivery information to people.

In the third configuration, the input interface has a plurality of input fields for inputting the contents of the distribution request and distribution information, and these input fields are configured in common for the plurality of networks. Means for transmitting and displaying screen data to the external terminal; and means for receiving from the external terminal information representing the contents of the distribution request and distribution information input in a plurality of input fields of the common input screen data. Prepare. Then, when the transmission information is generated in the network cooperation control module, the transmission information is generated based on the distribution request received by the input interface and information representing the contents of the distribution information.
With this configuration, the information distribution administrator can input necessary items without omission and error according to the displayed input support screen when inputting the distribution request and the contents of the distribution information. Thus, the efficiency of the input work can be increased. In addition, since the input support screen is configured in common for a plurality of networks, the administrator does not need to input dedicated distribution information for each of the plurality of networks. For this reason, the burden on the administrator can be reduced and the input work efficiency can be further increased.

According to a fourth configuration, when an activation packet sent from the external terminal via the communication network is received by the input interface, a unit that activates the plurality of network interfaces and the network cooperation control module; Means for receiving a distribution request sent from the external terminal via a communication network.
With this configuration, the administrator can input a distribution request to the information distribution apparatus using an external terminal such as a personal computer installed in a remote place or a portable terminal owned by the administrator. When a disaster such as an earthquake occurs, it is possible to promptly deliver information from anywhere.

  In short, according to the present invention, the information distribution function for the unspecified number of people is maintained even in a situation where communication failure is likely to occur, thereby enabling robust and reliable information distribution. A distribution device can be provided.

That is, in the personal computer PCC for the client, when the administrator selects “setting of notification call destination” in the menu downloaded from the user I / F 21 of the control server SV, the user I / F 21 of the control server SV The report call screen data is downloaded and displayed on the personal computer PCC. FIG. 15 shows an example of a notification call screen for disaster prevention broadcast / refuge radio broadcasting.

  As shown in FIG. 15, the notification call screen is provided with a destination input field, a siren transmission setting field, and an audio file transmission setting field. In the destination input column, “simultaneous”, “group”, “individual”, “shelter” and “master station” are displayed as the types of calls, and the administrator selects one of these.

  In the siren transmission setting column, “Siren number”, “viewing”, “volume”, “number of times”, and “transmission time difference” are displayed as setting items, and a “send button” is further displayed. For each of these items, the administrator selects a desired candidate from a plurality of candidates displayed in the input field.

  For example, for the “siren number”, numbers S00000001 to S99999999 are set in advance by the automatic numbering function for the type of siren, and the administrator selects a desired number from these siren numbers. When “view” is selected, the audio file of the selected siren number is downloaded from the control server SV to the personal computer PCC, thereby enabling the administrator to view the siren. For “volume”, a desired level is selected from 10 levels “1 to 10”. The “number of times” can be set in the range of “1 to 20”, and the manager selects a desired number of times from the range. The “transmission time difference” can be set in a range of 0 to 60 seconds in increments of 5 seconds, and the administrator selects a desired numerical value from this range.

  In the audio file transmission setting field, “file name”, “reference”, “viewing”, “volume”, “number of times”, “transmission time difference” are displayed as setting items, and “send button” is further displayed. ing. For each of these items, the administrator selects a desired candidate from a plurality of candidates displayed in the selection column.

For example, for “voice file”, file names or file IDs are assigned in advance to a plurality of voice messages stored in advance in the distribution information database, and the administrator inputs a desired file name or ID in the input field. To do. When “Browse” is selected, the list display screen of the plurality of file names is downloaded from the control server SV and displayed, and the administrator can select a desired file name from the displayed file names. Is possible. When “view” is selected, a voice message file corresponding to the selected file name or ID is downloaded from the control server SV to the personal computer PCC, thereby enabling the administrator to view the voice message. For “volume”, a desired level is selected from 10 levels “1 to 10”. The “number of times” can be set in the range of “1 to 20”, and the manager selects a desired number of times from the range. The “transmission time difference” can be set in a range of 0 to 60 seconds in increments of 5 seconds, and the administrator selects a desired numerical value from this range.
Note that destination setting processing for scheduled broadcasts is performed in the same manner. However, in the case of scheduled broadcasts, “Chime” is used instead of “Siren”.

(2-2) Creation of distribution request message
Assume that the selection input operation of necessary items on the notification call screen is completed, and the administrator presses the “send button” of the siren and the audio file. Then, the selection input information of the necessary items is sent as a distribution request from the client personal computer PCC to the user I / F 21 of the control server SV. When the distribution request is received by the user I / F 21, the control server SV uses the cooperation control response management module 24 based on the siren transmission setting information and the audio file transmission setting information among the necessary items sent as described below. Create a delivery request message.

  In other words, the format of the request message is set in common for the types of execution requests (scheduled broadcast execution request, content execution request, content transfer execution request, content transfer request, monitoring item collection request) used in this system. . FIG. 33 shows an example of the configuration of the header part of this request message format.

  In other words, the header (96 bytes) of the request message format includes a MessageID indicating the message type and the type of execution request (scheduled broadcast execution request, content execution request, content transfer execution request, content transfer request, monitoring item collection request). A message type that represents the time, a time stamp that sets the time, a content ID that represents the distribution content, a content type that represents the file type, a volume (00 to 10) that represents the volume, a repeat count that represents the number of playbacks, and playback Time Diff (00 to 60) representing the delay time until, Child NodeID (0001 to 9999) representing the slave station ID, Content Size representing the file size, and Start ContentID representing the type of start chime for the scheduled broadcast Start Content Type that represents the file type of the start chime for scheduled broadcasts, End Content ID that represents the type of the end chime for scheduled broadcasts, and scheduled broadcasts End Content Type representing a file type of termination chime, both of which are described as a string.

  The cooperative control response management module 24 of the control server SV describes the transmission setting information such as the chime / siren ID and the content ID of the voice message acquired from the client personal computer PCC in the header section of the request message. When the chime / siren voice file data and voice message voice file data need to be transmitted, the voice file data is read from the distribution information database in the data memory 14 and the body part of the request message Attach as Content Data. The audio file data has a variable length.

  Next, the cooperative control response management module 24 of the control server SV includes information indicating the type of call among the input information acquired from the personal computer PCC for the client, that is, “simultaneous”, “group”, “individual”, According to one of the “evacuation shelters”, the group of the corresponding destination and the slave station are specified. To specify the destination group and slave station, the group table 44, slave station attribute table 41, and slave station line table 42 in the slave station information management table are searched as shown in FIGS. 11 (a) and 11 (b). This is done by reading the corresponding group ID and group name, and the slave station ID and slave station name, respectively.

  Subsequently, for each identified slave station, a network type to be used for transmission of a distribution message is determined based on the read slave station ID, and a request message having the common format is determined based on the determination result. Is converted into a format corresponding to the communication protocol of the network. For example, when a request message is transmitted to the slave station SMI as an IP speaker or the slave station SMF for mini FM radio broadcasting using the IP network NW2, the request message is converted into a data format corresponding to TCP / IP. When a request message is transmitted to the portable slave station SMM using the cellular phone network NW1, it is converted into a data format corresponding to SMTP.

  Further, when a request message is transmitted to the MCA slave station SMA using the MCA wireless network NW3, it is performed as follows. That is, since the MCA system uses ARIB STD-T85, the cooperative control response management module 24 of the control server SV selectively reads out the voice file data of the voice message from the distribution information database in the data memory 14. The audio file data is converted into an analog audio signal.

(2-3) Transmission of Request Message When the creation of the request message and the data format conversion process are completed as described above, the cooperative control response management module 24 of the control server SV sends the transmission data of the distribution message having the format converted. It sorts and transfers to corresponding cooperation I / F 221-22n. The cooperative I / Fs 221 to 22n transmit the transferred transmission data of the distribution message to the distribution destination slave station according to a communication protocol defined by the connected network.

  On the other hand, each of the slave stations SMI, SMM, SMA, SMF receives the distribution message when the distribution message addressed to itself is transmitted from the control server SV. Then, based on the setting information of the siren and the voice file described in the distribution message, the siren sound and the voice message are reproduced as follows.

  For example, the slave station SMI corresponding to the IP network NW2 and the slave station SMM corresponding to the mobile phone network NW1 first generate a chime / siren sound based on the time stamp and the transmission time difference information described in the received distribution message. Determine the transmission timing. At the transmission timing, a chime / siren voice file stored in advance in the memory in the slave station is read based on the chime / siren ID described in the delivery message, and the chime / siren voice file is read out. Is decoded into an analog audio signal. Then, the decoded analog signal of the chime / siren sound is output loudly from the loudspeakers SPI and SPM.

  Next, the transmission timing of the voice message is determined based on the time stamp and the transmission time difference information described in the received distribution message. At the transmission timing, the voice file of the voice message stored in advance in the memory in the slave station is read based on the voice file ID described in the delivery message, and the voice file is decoded into an analog signal. . And the analog signal of this decoded voice message is loudly output from the loudspeakers SPI and SPM.

  When the slave station SMA corresponding to the MCA wireless network NW3 receives the distribution message including the chime / siren ID transmitted from the control server SV via the MCA transceiver AR, the slave station SMA is described in the received distribution message. The chime / siren sound sending timing is determined based on the time stamp and sending time difference information. At the transmission timing, a chime / siren voice file stored in advance in the memory in the slave station is read based on the chime / siren ID described in the delivery message, and the chime / siren voice file is read out. Is decoded into an analog audio signal. Then, the decoded analog signal of the chime / siren sound is output from the loudspeaker SPA. Subsequently, when the analog signal of the voice message is received from the control server SV via the MCA transceiver AR, the received analog signal of the voice message is supplied to the loudspeaker SPA to be output loudly.

  When a delivery message addressed to the local station arrives from the control server SV, the slave station SMF for mini FM radio broadcasting first receives a chime / siren sound based on the time stamp and the transmission time difference information described in the delivery message. Determine the transmission timing. At the transmission timing, a chime / siren voice file stored in advance in the memory in the slave station is read based on the chime / siren ID described in the delivery message, and the chime / siren voice file is read out. Is decoded into an analog audio signal. Then, the decoded analog signal of the chime / siren sound is converted into an FM modulation signal and transmitted to the shelter radio.

  Subsequently, the slave station SMF for mini FM radio broadcasting determines the voice message transmission timing based on the time stamp and the transmission time difference information described in the distribution message. Then, at the transmission timing, based on the voice message ID described in the delivery message, the voice message voice file stored in advance in the memory in the slave station is read, and this voice file is converted into an analog voice signal. Decrypt. Then, the decoded analog signal of the voice message is converted into an FM modulation signal and transmitted to the shelter radio.

  When receiving the request message, each slave station SMI, SMM, SMA, SMF creates a response message and returns it to the control server SV. Similar to the request message described above, the format of this response message is set in common for the type of execution request (completion response, monitoring item collection response) used in this system. FIG. 34 shows an example of the structure of the header part of this response message format.

  That is, in the header part (64 bytes) of the response message format, MessageID indicating the message type, Message Type indicating the type of execution request (completion response, monitoring item collection response), Time stamp for setting the time, and communication Result (00: normal, 01: error) indicating the result, Detail (00 to 99) indicating the details of the communication result in the case of an error, Child Node ID (0001 to 9999) indicating the slave station ID, and the slave station ID Power Supply (00: Normal, 01: Error) that represents the monitoring result of commercial power, which is a monitoring item, Battery (00: Normal, 01: Error), which represents the monitoring result of the storage battery that is a monitoring item of the slave station, and child Doors (00: normal, 01: error) representing the door opening monitoring result, which is a monitoring item of the station, are described as character strings.

  As described above, in this embodiment, between the control server SV and each of the slave stations SMM, SMI, SMA, and SMF distributed in the service area, the mobile phone network NW1, IP network NW2, and MCA network NW3 are used. Can be selectively connected. Further, the control server SV is provided with cooperative I / Fs 221 to 22n corresponding to the respective networks and a cooperative control response management module 24, and distribution from the personal computer PCC for clients is performed by the cooperative control response management module 24. In response to the input of the request, a request message for transmission to the plurality of slave stations is generated, converted into a format corresponding to the network using the data format of the request message, and then the corresponding cooperative I / Fs 221 to 22n To send to the slave station.

  Therefore, the request message is transmitted to the slave stations SMM, SMI, SMA, SMF selectively using the cellular phone network NW1, the IP network NW2, and the MCA network NW3. Even if it occurs, transmission information can be transmitted through another network. This makes it possible to distribute information that is robust and reliable against disasters. Further, the distribution information is not directly distributed to the user's personal portable terminal, but is once transmitted to the slave station and broadcasted to an unspecified number of people by voice broadcasting from the slave station. For this reason, it is possible to promptly deliver information to an unspecified number of people without omissions, even to people who do not have portable terminals, and without being greatly affected by network congestion.

  In addition, the chime / siren voice file and the voice message voice file are stored in advance in the memory in association with their content IDs in the slave stations SMM, SMI, and SMF. Then, the control server SV generates a request message including a content ID corresponding to the audio file to be distributed and transmits it to the slave station, and the slave stations SMM, SMI, and SMF correspond to the content ID specified by the request message. The voice file to be played is selectively read from the memory, and the voice represented by the read voice file is loudly output from the loudspeakers SPM, SPI, SPF.

  Therefore, the control server SV only needs to transmit the content ID of the audio file to the slave stations SMM, SMI, and SMF, and it is not necessary to transmit the audio file itself. It is possible to suppress the increase in This effect is particularly useful when network traffic increases rapidly, such as when a disaster occurs. Also, a chime / siren content ID notifying the start of broadcast is transmitted first, followed by a content ID of a voice message representing the broadcast content, and finally a chime / siren content ID notifying the end of the broadcast. Yes. For this reason, it becomes possible to alert | report broadcast more reliably, and it can alert | report broadcast content more reliably by using a chime and a siren separately by regular broadcast and disaster prevention broadcast.

  Furthermore, since the control server SV prepares a common input support screen for a plurality of networks and provides it to the personal computer PCC for the client, the administrator displayed it when inputting the distribution request. According to the input support screen, it becomes possible to input necessary items without omissions and without errors, thereby increasing the efficiency of input work. In addition, since the input support screen is configured in common for a plurality of networks, the administrator does not need to input dedicated distribution information for each of the plurality of networks. For this reason, the burden on the administrator can be reduced and the input work efficiency can be further increased.

  The present invention is not limited to the above embodiment. For example, in the embodiment described above, the control server SV and the client personal computer PCC are both installed in the disaster prevention center CT, and the two are connected by, for example, a USB cable. However, the operation of the control server SV may be remotely controlled from a client personal computer PCC or a portable terminal MSC installed far away from the disaster prevention center.

  This configuration can be realized as follows, for example. FIG. 35 is a schematic diagram showing the configuration. That is, specific packet data called Magic Packet is sent from the client personal computer PCC or mobile terminal MSC installed at a distance to the management web of the router RT for WOL (Wakeup On LAN) via the IP network NW2. . As a result, the activation packet is transmitted from the WOL-compatible router RT to the control server (master station) SV, and the control server SV is turned on by this activation packet. In this state, data is transmitted / received to / from the control server SV using the browser function of the client personal computer PCC or portable terminal MSC. Thereby, a distribution request, registration of slave station information, and the like can be performed with respect to the control server SV from a personal computer PCC for a remote client or the mobile terminal MSC.

In addition, the configuration of the control server SV, the control procedure and control contents, the configuration of each slave station, and the like can be variously modified and implemented without departing from the gist of the present invention.
