Description

Technical Field

[0001] Embodiments of the present invention relate to a disaster prevention information system, a mass command device, and a method for remotely operating the mass command device.

Background Art

[0002] The prefectural disaster prevention radio network is a network that plays an active role as a private radio line when the ground infrastructure cannot be used in the event of a disaster within the prefecture. The prefectural disaster prevention radio network is provided with a mass command system that performs mass data distribution from the prefectural government office to each city, town, and village, fire department, insurance office, disaster prevention-related institution, etc. within the prefecture.

[0003] When a local disaster occurs that is limited to a part of the prefecture, the disaster countermeasure headquarters may be established not in the prefectural government office but in a joint government building, city hall, etc. in the affected area or its vicinity. However, since the command authority of the mass command system lies only with the prefectural government office, even when the disaster countermeasure headquarters is established in a joint government building, city hall, etc. in the case of a local disaster, the disaster countermeasure headquarters cannot have the command authority.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As a means of communication when a disaster countermeasure headquarters is established in a contract building or a city hall, for example, it is conceivable to use disaster prevention radio. However, in the prefectural disaster prevention radio system, only about 1 to 2 lines of radio telephone and facsimile are provided at each station, so it mainly communicates with the prefectural government office and is insufficient as a communication line with neighboring municipalities, jurisdictional health centers, fire departments, etc.

[0006] In addition, as a means of communication different from transmission by radio telephone or facsimile, there is the aforementioned prefectural-wide simultaneous command system, but it is not realistic in terms of cost to fixedly install multiple sets of the same equipment for several minutes of the stations that should have the command authority.

[0007] Embodiments of the present invention provide a disaster prevention information system, a simultaneous command device, and a method for remotely operating a simultaneous command device that can utilize the simultaneous command system as a local information sharing means by remote operation from the receiving terminal side of the simultaneous command system.

Means for Solving the Problems

[0008] According to the embodiment, in the disaster prevention radio system, a central control station and a plurality of regional stations transmit and receive disaster prevention information via a satellite communication line, a terrestrial radio communication line, and a wired communication line. The central control station includes a simultaneous command device having a simultaneous command processing unit that simultaneously distributes disaster prevention information to a plurality of regional stations using a satellite communication line, a terrestrial radio communication line, and a wired communication line. Each of the plurality of regional stations includes a receiving terminal that receives disaster prevention information from the simultaneous command device. The receiving terminal has a command client function unit that transmits local information to be provided to one or more other receiving terminals to the simultaneous command device using a wired communication line and requests distribution of the local information to one or more other receiving terminals. The simultaneous command device further has a remote operation function unit that instructs the simultaneous command processing unit to simultaneously distribute local information to one or more other receiving terminals using a satellite communication line, a radio communication line, and a wired communication line in response to a request from the receiving terminal.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described with reference to the drawings.

[0011] FIG. 1 is a diagram showing a configuration example of a prefecture-wide simultaneous command system (disaster prevention information system) 1 according to an embodiment. Hereinafter, wherever it should be described as "prefecture", for the sake of simplicity of notation, only the notation of "prefecture" will be used, but it may be used for any of the prefectures.

[0012] The prefecture-wide simultaneous command system 1 is a system that performs simultaneous data distribution from the prefectural office (central control office) 10 to each office (regional office) 20 within the prefecture. Each office 20 within the prefecture is, for example, a prefectural branch, a consolidated office / vitalization bureau, a municipality within the prefecture, a fire headquarters, a field office within the prefecture, a related organization, etc. In FIG. 1, offices 20[A] such as prefectural branches and consolidated offices / vitalization bureaus, offices 20[B] such as municipalities within the prefecture and fire headquarters, and offices 20[C] such as field offices within the prefecture and related organizations are illustrated. The prefectural office (central control office) 10 is further connected to the Meteorological Agency 30 via the local meteorological observatory 40 in order to acquire meteorological information.

[0013] A plurality of communication lines such as a satellite communication line 51, a multiplex wireless line 52, and a wired line (such as a prefecture-wide information highway) 53 are provided between the simultaneous command device 11 of the prefectural office 10 and the receiving terminals 21 of each office 20. In the prefectural office 10, a simultaneous command device 11, a scanner / data simultaneous distribution operation console (hereinafter referred to as a simultaneous distribution operation console) 12, and an XML relay server 13 are arranged.

[0014] The simultaneous command device 11 is a device that distributes various data to the receiving terminals 21 of each office 20. The simultaneous distribution operation console 12 is connected to the simultaneous command device 11, creates various data to be distributed to the receiving terminals 21 of each office 20, and performs an operation of instructing the simultaneous command device 11 to distribute the various data. The XML relay server 13 is a device that transfers the prefecture-wide meteorological information sent from the local meteorological observatory 40 to the simultaneous command device 11. On the other hand, a receiving terminal 21 is arranged in each office 20. The receiving terminal 21 is a device that receives various data distributed from the simultaneous command device 11 of the prefectural office 10.

[0015] In the prefecture-wide command system 1, there are three types of data distribution that can be implemented: "Weather-wide", "Data-wide", and "Scanner-wide".

[0016] "Weather-wide" is data distribution for distributing weather advisories and the like from the JMA's 30 Ades system. The JMA's 30 Ades system transmits national weather information and the like in XML format or PDF format to local meteorological observatories 40 across the country via dedicated lines. Each prefecture's local meteorological observatory 40 performs filtering to extract in-prefecture weather information from the national weather information and the like sent from the JMA's 30 Ades system. The local meteorological observatory 40 transmits the extracted in-prefecture weather information to the XML relay server 13 of the prefectural government 10 in XML format or PDF format via a dedicated line. The in-prefecture weather information sent to the XML relay server 13 is transferred to the mass command device 11.

[0017] The mass command device 11 transmits the in-prefecture weather information received from the XML relay server 13 to the receiving terminals 21 of each station 20 using the satellite communication line 51, the multi-radio line 52, or the wired line 53. When the receiving terminal 21 receives the in-prefecture weather information via the satellite communication line 51, the multi-radio line 52, or the wired line 53, it returns a response or the like. The same applies to "Data-wide" and "Scanner-wide" described later.

[0018] "Data-wide" is data distribution for distributing the text and attached data created on the prefectural government command facility (mass distribution operation desk 12). The mass command device 11 receives an instruction from the mass distribution operation desk 12 and transmits the text and attached data passed from the mass distribution operation desk 12 to the receiving terminals 21 of each station 20 using the satellite communication line 51, the multi-radio line 52, or the wired line 53. The mass command device 11 can also select the stations 20 to be distributed to.

[0019] "Scanner Broadcast" is data distribution for reading paper manuscripts on the prefectural government-ordered equipment (simultaneous distribution operation desk 12) and converting them into TIFF files for distribution. The simultaneous command device 11 receives an instruction from the simultaneous distribution operation desk 12 and transmits the TIFF file passed from the simultaneous distribution operation desk 12 to the receiving terminals 21 of each station 20 using the satellite communication line 51, the multiplex wireless line 52, and the wired line 53. Similar to the aforementioned "Data Broadcast", in "Scanner Broadcast" as well, the simultaneous command device 11 can select the stations 20 to be distributed to.

[0020] In this way, the prefectural-wide simultaneous command system 1 is basically a system in which the command facilities exist only in the prefectural government 10. In contrast, the prefectural-wide simultaneous command system 1 of the embodiment is configured to be able to utilize the prefectural-wide simultaneous command system 1 as a local information sharing means between each station 20 by remote operation from the receiving terminal 21 side when the ground infrastructure cannot be used in the event of a disaster. In other words, the prefectural-wide simultaneous command system 1 of the embodiment is provided with a mechanism that allows each station 20 to temporarily hold the distribution command authority by the simultaneous command device 11.

[0021] Next, FIG. 2 is a diagram for explaining the communication lines in the prefectural-wide simultaneous command system 1 of the embodiment. In FIG. 2, only stations 20[A] and 20[B] among the stations 20[A], 20[B], and 20[C] shown in FIG. 1 are illustrated.

[0022] In FIG. 2, the dashed arrow connecting the prefectural government (prefectural government control bureau) 10 and each station 20 indicates the communication line. On the other hand, the solid arrow indicates the simultaneous command line. That is, the communication lines in the prefectural-wide simultaneous command system 1 are not limited to those for simultaneous commands described with reference to FIG. 1 and can also be used for communication.

[0023] As the communication lines in the prefectural-wide simultaneous command system 1, a satellite communication line 51, a multiplex wireless line 52, a wired line 53, and a mobile wireless line 54 are provided. The prefectural government office (Prefectural Government Control Bureau) 10 includes, in addition to the aforementioned mass instruction device 11 and mass distribution operation desk 12, and the XML relay server 13, a disaster prevention relay switch 14, a cordless phone 141, and a wireless facsimile 142. The disaster prevention relay switch 14 is a device that exchanges and connects between the cordless phone 141 or the wireless facsimile 142 and the satellite communication line 51, the multiplex wireless line 52, or the mobile wireless line 54.

[0024] The cordless phone 141 is a device that transmits and receives voice with the cordless phone 221 on the station 20 side via the disaster prevention relay switch 14. The cordless phone 141 has a function of inputting voice and converting it into an electrical signal, and a function of converting an electrical signal into voice and outputting it. The wireless facsimile 142 is a device that transmits and receives black and white originals with the wireless facsimile 22 on the station 20 side via the disaster prevention relay switch 14. The wireless facsimile 142 has a function of reading documents and converting them into electrical signals, and a function of demodulating the electrical signals into the read documents and printing them. Furthermore, a scanner 121 is connected to the mass distribution operation desk 12. The scanner 121 is a device that reads a paper manuscript and converts it into a TIFF file during the aforementioned "Scanner Mass" operation.

[0025] Next, stations 20 such as the prefectural branches, consolidated offices / vitalization bureaus, etc. 20[A], and the prefectural municipalities, fire departments, etc. 20[B] include the aforementioned receiving terminal 21, a disaster prevention switch 22, a cordless phone 221, and a wireless facsimile 222.

[0026] The disaster prevention switch 22 is a device that exchanges and connects between the cordless phone 221 or the wireless facsimile 222 and the satellite communication line 51, the multiplex wireless line 52, or the mobile wireless line 54. In FIG. 2, the disaster prevention switch 22 of the prefectural branches, consolidated offices / vitalization bureaus, etc. 20[A] exchanges and connects between the cordless phone 221 or the wireless facsimile 222 and the satellite communication line 51 or the multiplex wireless line 52, and the disaster prevention switch 22 of the prefectural municipalities, fire departments, etc. 20[B] exchanges and connects between the cordless phone 221 or the wireless facsimile 222 and the satellite communication line 51 or the mobile wireless line 54.

[0027] The wireless phone 221 is a device that transmits and receives voice signals to and from the wireless phone 141 on the prefectural government office 10 side via the disaster prevention switch 22. Similar to the wireless phone 141 on the prefectural government office 10 side, the wireless phone 221 has a function of inputting voice and converting it into an electrical signal, and a function of converting the electrical signal back into the original voice and outputting it. The wireless fax 222 is a device that transmits and receives the paper manuscript read between the wireless fax 142 on the prefectural government office 10 side via the disaster prevention switch 22. Similar to the wireless fax 142 on the prefectural government office 10 side, the wireless fax 222 has a function of reading documents and converting them into electrical signals, and a function of demodulating the electrical signals into the read documents and printing them.

[0028] In addition, a multifunction device 211 is connected to the receiving terminal 21. Here, the multifunction device 211 is a device equipped with various functions such as a scanner, a FAX, and a printer that can print the paper manuscript converted into the TIFF file.

[0029] By the way, it is common from the cost aspect and the like that only about two lines of communication lines for disaster prevention radio are prepared in each station 20. Therefore, if a disaster countermeasure headquarters is established in the station 20 near the disaster area due to a local disaster (when the station 20 becomes a disaster countermeasure base), it is expected that the communication line of that station 20 will be occupied for communication with the prefectural government office 10.

[0030] Therefore, in this case, it is highly likely that it will be practically impossible to use the disaster prevention radio for information sharing between the station 20 and neighboring stations 20 instead of the ground infrastructure that has become unusable due to the disaster.

[0031] Here, focusing again on the dedicated command line within the prefectural-wide command system 1, for example, during periods when the receiving terminals 21 of the stations 20 serving as disaster response bases are not receiving the distribution from the dedicated command device 11 of the prefectural government office 10, the line between the station 20 and the dedicated command device 11 is in an idle state. Therefore, the prefectural-wide command system 1 of the embodiment utilizes the idle state of the dedicated command line so that the prefectural-wide command system 1 can be utilized as a means for local information sharing among the stations 20 through remote operation from the receiving terminal 21 side.

[0032] Subsequently, FIG. 3 is a diagram for explaining the remote utilization from each station 20 of the prefectural-wide command system 1 of the embodiment. Also in FIG. 3, similar to FIG. 2, only stations 20[A] and 20[B] are illustrated.

[0033] In FIG. 3, the dashed-dotted line arrows connecting the prefectural government office (prefectural government control office) 10 and each station 20 indicate the lines (hereinafter, remote operation lines) used for remote operation (from the receiving terminal 21 to the dedicated command device 11) and data transfer (from the receiving terminal 21 to the dedicated command device 11). On the other hand, the dashed line arrows indicate the dedicated command lines. More specifically, the dashed line arrows show the state in which the prefectural-wide command system 1 is utilized as a means for information sharing with neighboring stations 20 by the receiving terminal 21 remotely operating the dedicated command device 11 using the remote operation line.

[0034] As shown in FIG. 3, in the prefectural-wide command system 1 of the embodiment, the wired line 53, which is a part of the multiple lines including the satellite communication line 51, the multi-radio line 52, and the wired line 53, prepared for the dedicated command device 11 of the prefectural government office 10 to distribute data to the receiving terminals 21 of each station 20, is used as a remote operation line during the period when the distribution from the dedicated command device 11 is not being performed. Note that the prefectural-wide command system 1 of the embodiment basically assumes using the wired line 53 as the remote operation line, but it is also possible to use the multi-radio line 52 as the remote operation line, not limited to the wired line 53.

[0035] That is, the in-prefecture simultaneous command system 1 of the embodiment is provided with a function in which the simultaneous command device 11 receives commands from the receiving terminal 21 via the wired line 53. On the other hand, the receiving terminal 21 is provided with a function of remotely operating the simultaneous command device 11 via the wired line 53.

[0036] In addition, for the wired line 53 installed in the in-prefecture simultaneous command system 1, in terms of cost, etc., a narrow-bandwidth line such as 200 Kbps to 300 Kbps is common. Therefore, in the in-prefecture simultaneous command system 1 of the embodiment, the functions added for remotely operating the simultaneous command device 11 from the receiving terminal 21 take into account the use of narrow-bandwidth lines.

[0037] FIG. 4 is a functional block diagram regarding the remote operation of the simultaneous command device 11 by the receiving terminal 21 of the in-prefecture simultaneous command system 1 of the embodiment.

[0038] In the prefectural office (Prefectural Office Control Bureau) 10, the aforementioned simultaneous command device 11, simultaneous distribution operation console 12, and XML relay server 13, a network switch (SW) 15, and a weather information viewing terminal 16 are provided.

[0039] The network switch (SW) 15 is a network switch that executes the distribution of transmission and reception data for devices (such as the simultaneous command device 11 and XML relay server 13) within the prefectural office 10 to communicate using a plurality of lines. The network switch 15 also executes the distribution of transmission and reception data for communication between devices within the prefectural office 10. In addition, the weather information viewing terminal 16 is a terminal for viewing weather information sent from the local meteorological observatory 40.

[0040] In FIG. 4, the simultaneous command device 11 has one or more simultaneous command control devices 110. An example in which two simultaneous command control devices 110 (#1, #2) exist is shown. When there are multiple simultaneous command control devices 110, these share and install the functions that the simultaneous command device 11 should have and operate in cooperation with each other.

[0041] In addition, the mass distribution operation console 12 is provided with a mass command console 120. FIG. 4 shows an example in which two mass distribution operation consoles 12 (12-1, 12-2), a main console and a sub console, are provided. The operation screen displayed on the receiving terminal 21 by the browser (Web browser) 210 imitates this mass command console 120. Note that the mass command console 120 may also be displayed as an operation screen by the browser operating on the mass distribution operation console 12, similar to the receiving terminal 21.

[0042] On the other hand, each station 20 is also provided with a network switch (SW) 23 that executes distribution of transmission and reception data for communication of devices (receiving terminal 21, multifunction device 211, receiving notification device 212, etc.) at each station 20 using a plurality of lines. The network switch 23, similar to the network switch 15 in the prefectural office 10, also executes distribution of transmission and reception data for communication between devices within each station 20. Note that the receiving notification device 212 is a device that notifies that the distribution from the mass command device 11 has been received.

[0043] In the in-prefecture mass command system 1 of the embodiment, first, the mass command control device 110 has a function of receiving a command from the receiving terminal 21. More specifically, the mass command control device 110 transmits an HTML file for displaying an operation screen imitating the mass distribution operation console 12 to the browser 210 in response to a request by communication conforming to, for example, the HTTPS protocol using the wired line 53 from the browser 210 operating on the receiving terminal 21. That is, in the in-prefecture mass command system 1 of the embodiment, it is assumed that the browser 210 is installed on the receiving terminal 21. Note that installation of the browser 210 is not required for the receiving terminal 21 of the station 20 that does not plan to remotely operate the mass command device 11.

[0044] As described above, since the remote operation of the mass instruction device 11 of the prefectural office 10 by each receiving terminal 21 of each station 20 is executed by using the available capacity of the wired line 53, the operator of the receiving terminal 21 checks that there is no distribution from the mass instruction device 11, then starts the browser 210, inputs a predetermined URL, and accesses the mass instruction control device 110.

[0045] The browser 210 of the receiving terminal 21 that has acquired the HTML file from the mass instruction control device 110 displays an operation screen imitating the mass distribution operation desk 12 on the receiving terminal 21. The operator of the receiving terminal 21 performs an operation for causing the mass instruction device 11 to execute the aforementioned "data mass" or "scanner mass" on the operation screen displayed by the browser 210.

[0046] The content set on the operation screen is transmitted from the browser 210 to the mass instruction control device 110 as communication data in a format conforming to the aforementioned HTTPS protocol. The mass instruction control device 110 that has received this communication data executes control of the mass instruction device 11 for executing "data mass" or "scanner mass" based on the communication data.

[0047] In addition, when there are a plurality of operation screens to be displayed by the browser 210 on the receiving terminal 21, for example, a main screen and one or more sub - screens, the transition between the plurality of operation screens is realized by the configuration of the HTML file transmitted from the mass instruction control device 110 to the browser 210. For example, the mass instruction control device 110 first transmits an HTML file for the main screen to the receiving terminal 21. The HTML file for the main screen is configured such that when an operation for moving to any sub - screen is performed on the main screen, communication data indicating that is transmitted from the browser 210 to the mass instruction control device 110. The mass instruction control device 110 that has received the communication data then transmits an HTML file for the sub - screen to the receiving terminal 21.

[0048] Therefore, for example, by preparing a group of HTML files according to the transition pattern of the operation screen of the mass distribution operation console 12, the operation screen of the mass distribution operation console 12 can be almost faithfully reproduced as the operation screen displayed by the browser 210 on the receiving terminal 21.

[0049] Note that the screen for remotely operating the mass command device 11, which is to be displayed by the browser 210 on the receiving terminal 21, does not necessarily have to mimic the operation screen of the mass distribution operation console 12. For example, it may be a simple screen for performing the minimum necessary operations among all the operations that can be performed on the mass distribution operation console 12.

[0050] As described above, in the in-county mass command system 1 of the embodiment, the mass command device 11 does not occupy a line and does not require a wide-bandwidth line, and accepts remote operations from the receiving terminal 21 through communication conforming to, for example, the HTTPS protocol applied to Internet communication in a cloud system. That is, the in-county mass command system 1 of the embodiment provides an interface for the receiving terminal 21 to remotely operate the mass command device 11, which is suitable for a narrow-bandwidth wired line 53.

[0051] In the mass command device 11 in the in-county mass command system 1 of the embodiment, the mass command control device 110 can accept remote operations from the receiving terminal 21. Along with this, the mass command control device 110 needs to manage the priorities of the instructions from the mass distribution operation console 12 (12-1, 12-2) and the instructions from the receiving terminals 21 of each station 20.

[0052] Therefore, the mass instruction control device 110 further has a function of managing the priorities between instructions from the mass distribution operation console 12 (12-1, 12-2) and instructions from the receiving terminals 21 of each station 20. More specifically, the mass instruction control device 110 treats the mass distribution operation console 12 (main) as a client with the highest priority, and treats the mass distribution operation console 12 (sub) as a client with the second highest priority. Regarding the receiving terminals 21 of the plurality of stations 20, they are treated as clients with a priority lower than that of the mass distribution operation console 12 (sub), and the priorities between the receiving terminals 21 may be adaptively determined, for example, according to the order of receiving remote operations, or may be set in advance.

[0053] FIG. 5 is a functional block diagram regarding the remote operation of the mass instruction device 11 from the receiving terminal 21 for the mass instruction control device 110 and the receiving terminal 21 in the in-prefecture mass instruction system 1 of the embodiment.

[0054] In FIG. 5, the mass instruction control device 110 includes a Web server software 111, an operation console screen data transmission control unit 112, a mass instruction processing unit 113, and a database (DB) 114. The Web server software 111 and the operation console screen data transmission control unit 112 constitute a remote operation functional unit for realizing the remote operation of the mass instruction device from the receiving terminal 21. The operation console screen data transmission control unit 112 and the mass instruction processing unit 113 may be realized by the CPU executing a program, or may be realized by hardware such as an electric circuit. The database 114 is realized using a storage medium such as an HDD or an SSD.

[0055] The Web server software 111 controls communication with the Web browser (browser) 210 operating on the receiving terminal 21 of each station 20. Further, the Web server software 111 executes authentication of the receiving terminal 21 or the operator of the receiving terminal 21 via the browser 210. The data for authentication is stored in the database 114.

[0056] Also, the Web server software 111 manages the number of browsers 210 that can be accessed simultaneously. After the number of connections of the browser 210 reaches the limit number, if the Web server software 111 receives access from another browser 210, the Web server software 111 notifies the browser 210 of an error. The connection limit number of the browser 210 is stored in the database 114.

[0057] When the console screen data transmission control unit 112 receives access from the browser 210 via the Web server software 111 and the authentication is successful, the console screen data transmission control unit 112 transmits an HTML file for displaying an operation screen imitating the batch distribution console 12 to the browser 210 via the Web server software 111. This HTML file is also stored in the database 114.

[0058] The console screen data transmission control unit 112 receives communication data indicating the operation content on the operation screen displayed on the receiving terminal 21 by the HTML file transmitted to the browser 210 via the Web server software 111. When this communication data indicates an operation for moving to another operation screen, the console screen data transmission control unit 112 transmits an HTML file for the other operation screen to the browser 210 via the Web server software 111.

[0059] Also, when the communication data includes, for example, an instruction of "data batch" and the target text and distribution destination of the "data batch", the console screen data transmission control unit 112 stores the target text and distribution destination in the database 114 and instructs the batch command processing unit 113 to execute the "data batch".

[0060] When the batch command processing unit 113 is instructed to execute "data batch" or "scanner batch" from the console screen data transmission control unit 112, the batch command processing unit 113 reads out the corresponding target text or target TIFF file and distribution destination from the database 114, and executes "data batch" or "scanner batch" for distributing the target text or target TIFF file to the distribution destination.

[0061] The batch instruction processing unit 113 can also receive instructions of "data batch" or "scanner batch" from the main batch distribution operation console 12-1 or the sub batch distribution operation console 12-2. Therefore, the batch instruction processing unit 113 manages the priorities of the main batch distribution operation console 12-1, the sub batch distribution operation console 12-2, and the browser 210. Specifically, the batch instruction processing unit 113 gives priority to the instructions from the main batch distribution operation console 12-1 over the instructions from the sub batch distribution operation console 12-2, and gives priority to the instructions from the sub batch distribution operation console 12-2 over the instructions from the browser 210.

[0062] For example, when the batch instruction processing unit 113 receives instructions from the main batch distribution operation console 12-1 and the browser 210 at approximately the same timing, it first executes the process instructed by the main batch distribution operation console 12-1. At this time, for the process instructed by the browser 210, the batch instruction processing unit 113 maintains it in a buffered state by the database 114.

[0063] If, while the process instructed by the main batch distribution operation console 12-1 is being executed and the process instructed by the browser 210 is in the buffered state, the batch instruction processing unit 113 further receives an instruction from the sub batch distribution operation console 12-2, it buffers to the database 114 while swapping the order in order to start the process instructed by the sub batch distribution operation console 12-2 prior to the process instructed by the browser 210.

[0064] Note that, for example, when instructions from the main batch distribution operation console 12-1 are continuous, instructions from the sub batch distribution operation console 12-2 or the browser 210 will continue to be held in abeyance. Therefore, the batch instruction processing unit 113 may take measures such as starting when the elapsed time since buffering exceeds the threshold value. On the one hand, the receiving terminal 21 is provided with the aforementioned Web browser (browser) 210. The browser 210, in cooperation with the aforementioned remote operation function unit, constitutes a command client function unit for realizing the remote operation of the mass command device from the receiving terminal 21.

[0065] Here, with reference to FIGS. 6 to 9, in the in-county mass command system 1 of the embodiment, a specific example of remotely operating the mass command device 11 with the receiving terminal 21 of each station 20 and utilizing the in-county mass command system 1 as a means for information sharing with neighboring stations 20 will be described.

[0066] FIG. 6 is a diagram showing an example of a situation where a local disaster has occurred within the county.

[0067] Here, as shown in FIG. 6, it is assumed that the in-county mass command system 1 of the embodiment is provided in a county that is roughly divided into the east, north, south, and west. Also, it is assumed that the prefectural office (prefectural office control bureau) 10 exists in the eastern part of the prefecture. As described above, the command authority of the in-county mass command system 1 basically lies with the prefectural office 10.

[0068] And in such a prefecture, assume a case where a local disaster has occurred in City AA in the western part of the prefecture, far from the prefectural office 10. Also, assume that due to this disaster, all communication infrastructures have been destroyed, and in and around City AA, communication cannot be established by communication infrastructures (other than the disaster prevention radio installed in the in-county mass command system 1).

[0069] FIG. 7 is a diagram showing an example of the communication line between the prefectural office 10 and each station 20 in City AA, which is installed in the in-county mass command system 1.

[0070] The lines (satellite communication line 51, multi-radio line 52, wired line 53) maintained by the prefecture-wide simultaneous instruction system 1 are maintained as robust facilities that can operate by means of emergency power generation or the like even during disasters. Therefore, as shown in Fig. 7, the communication lines for "data simultaneous" or "scanner simultaneous" between the prefectural office (Prefectural Office Control Bureau) 10 and each office 20 in and around City AA are in a usable state. However, conventionally, the lines of the prefecture-wide simultaneous instruction system 1 could only execute "data simultaneous" or "scanner simultaneous" from the prefectural office 10 to each office 20 under the command authority of the prefectural office 10.

[0071] Fig. 8 is a diagram showing an example of the flow of operations for executing "data simultaneous" from the prefectural office 10 to each office 20 under the command authority of the prefectural office 10 in the prefecture-wide simultaneous instruction system 1.

[0072] (1) When executing "data simultaneous" from the prefectural office 10 to each office 20 under the command authority of the prefectural office 10, first, at the simultaneous distribution operation console 12, a distribution text and attached files are created.

[0073] Next, in (2), at the simultaneous distribution operation console 12, the distribution destination groups of each office 20 including City AA and its surrounding areas to which the distribution text and attached files are to be distributed are specified.

[0074] Then, in (3), at the simultaneous distribution operation console 12, a transmission operation is performed to instruct the simultaneous instruction device 11 to distribute the distribution text and attached files to the specified distribution destination groups.

[0075] Thereby, information transmission from the prefectural office 10 to each office 20 is achieved. Also, communication means between the prefectural office 10 and each office 20 are ensured by disaster prevention radios such as radiotelephones and facsimiles deployed in the prefecture-wide simultaneous instruction system 1.

[0076] However, if a disaster prevention headquarters is established in Bureau 20 such as the joint government building or city hall in AA City, the disaster prevention radios such as the wireless phones and fax machines in that Bureau 20 will be occupied for communication with the prefectural government office 10, and it is expected that it will be difficult to transmit information to neighboring Bureaus 20.

[0077] Therefore, in the prefecture-wide simultaneous command system 1 of the embodiment, during the period when the simultaneous command device 11 is not performing data distribution, the receiving terminal 21 of Bureau 20 on the AA City side remotely operates the simultaneous command device 11 by utilizing the available line, for example, enabling the information from the AA City to be distributed to Bureaus 20 around the AA City using the simultaneous command device 11. Also, it is assumed that such remote operation can be carried out over a narrow bandwidth line.

[0078] FIG. 9 is a diagram showing an example of the flow of the operation of transmitting information from Bureau 20 under the command authority of a certain Bureau 20 in the prefecture-wide simultaneous command system 1 from the prefectural government office 10 to neighboring Bureaus 20 by "data synchronization".

[0079] For example, in Bureau 20 of AA City where a disaster prevention headquarters is established, the receiving terminal 21 receives data distribution from the simultaneous command device 11 of the prefectural government office 10. Here, it is assumed that the disaster prevention radios such as the wireless phones and fax machines of this Bureau 20 deployed in the prefecture-wide simultaneous command system 1 are occupied for communication with the prefectural government office 10. That is, it is assumed that the situation is such that information cannot be transmitted from Bureau 20 of AA City to neighboring Bureaus 20 using the disaster prevention radio.

[0080] In such a situation, when it becomes necessary to transmit information from Bureau 20 of AA City to neighboring Bureaus 20 around the AA City, the operator of the receiving terminal 21 of Bureau 20 in AA City first checks whether the receiving terminal 21 is receiving data distribution from the simultaneous command device 11. In other words, the simultaneous command device 11 checks whether it is executing a simultaneous command.

[0081] When the receiving terminal 21 is not receiving data distribution from the mass command device 11, the operator of the receiving terminal 21 starts the browser 210 on the receiving terminal 21 and enters the URL for accessing the mass command device 11. When the number of connections of the browser 210 to the mass command device 11 has not reached the limit number, for example, an HTML file for displaying a screen for remotely operating the mass command device 11, which imitates the screen of the mass distribution operation console 12, is provided from the mass command device 11. Using the HTML file acquired from the mass command device 11, the browser 210 displays, on the receiving terminal 21, a screen for remotely operating the mass command device 11.

[0082] On this operation screen, the operator of the receiving terminal 21 performs an operation for causing the mass command device 11 to execute, for example, "data mass distribution". Specifically, a distribution text and an attached file are created (1), each destination group of the stations 20 including AA City and the vicinity of AA City to which the distribution text and the attached file are to be distributed is specified (2), and a transmission operation for instructing the distribution of the distribution text and the attached file to the specified destination group is performed (3).

[0083] The operation content on the operation screen is transmitted by the browser 210 to the mass command control device 110 as communication data in a format compliant with, for example, the HTTPS protocol. By performing communication for remotely operating the mass command device 11 from the receiving terminal 21 in accordance with, for example, the HTTPS protocol, the line between the receiving terminal 21 and the mass command device 11 can be used spotwise for remote operation. Also, transmission and reception of communication data are possible even with a narrow bandwidth line.

[0084] The mass command device 11 that has received the communication data from the browser 210 executes mass distribution of the distribution text and the attached file included in the communication data to the destinations indicated by the communication data.

[0085] Thereby, information transmission from the station 20 in AA City to the station 20 in the vicinity of AA City is realized by utilizing the mass distribution function of the mass command device 11.

[0086] In this way, the in-prefecture simultaneous command system 1 of the embodiment can utilize the in-prefecture simultaneous command system 1 as a local information sharing means by remote operation from the receiving terminal 21.

[0087] FIG. 10 is a flowchart showing the operation flow of the receiving terminal 21 when the simultaneous command device 11 of the prefectural office 10 executes simultaneous distribution by remote operation from the receiving terminals 21 of the respective stations 20 in the in-prefecture simultaneous command system 1 of the embodiment.

[0088] In step S101, the receiving terminal 21 first activates the browser 210. The activation of the browser 210 is performed after the operator of the receiving terminal 21 confirms that the receiving terminal 21 is not receiving data distribution from the simultaneous command device 11.

[0089] In step S102, the receiving terminal 21 accesses the simultaneous command device 11 via the browser 210. This access is performed by the operator of the receiving terminal 21 inputting a predetermined URL into the browser 210.

[0090] Next, in step S103, the receiving terminal 21 determines whether the connection to the simultaneous command device 11 has been successful. If an error is notified from the simultaneous command device 11 and the connection to the simultaneous command device 11 fails (step S103: NO), the receiving terminal 21 retries the process of step S102.

[0091] If the connection to the simultaneous command device 11 is successful (step S103: YES), the process proceeds to step S104, and the receiving terminal 21 displays an operation screen using the HTML file provided by the simultaneous command device 11 via the browser 210. This operation screen is, for example, a screen for remotely operating the simultaneous command device 11 that imitates the screen of the simultaneous distribution operation console 12.

[0092] In step S105, the receiving terminal 21 (the operator of the receiving terminal 21) selects either "Data All at Once" or "Scanner All at Once" on the operation screen displayed by the browser 210.

[0093] Also, in step S106, the receiving terminal 21 (the operator of the receiving terminal 21) performs an operation of designating a distribution destination and a distribution target and instructing the execution of distribution on the operation screen displayed by the browser 210.

[0094] As described above, the mass instruction device 11 may receive two or more instructions from the mass distribution operation desk (main) 12-1, the mass distribution operation desk (sub) 12-2, and the plurality of browsers 210 at substantially the same timing. Therefore, the mass instruction device 11 executes the process (mass distribution) corresponding to the instruction with a high priority and buffers the process corresponding to the instruction with a low priority. Accordingly, the mass distribution instructed by the receiving terminal 21 is not always immediately executed in the mass instruction device 11.

[0095] In step S107, the receiving terminal 21 waits for a response from the mass instruction device 11 and displays the distribution result notified from the mass instruction device 11 by the browser 210.

[0096] In step S108, the receiving terminal 21 (the operator of the receiving terminal 21) stops the browser 210 after confirming the distribution result.

[0097] FIG. 11 is a flowchart showing the flow of the operation of the mass instruction device 11 when the mass instruction device 11 of the prefectural office 10 executes mass distribution by remote operation from the receiving terminal 21 of each station 20 in the in-prefecture mass instruction system 1 of the embodiment.

[0098] In step S201, the mass instruction device 11 first determines whether there is an access from the receiving terminal 21.

[0099] When receiving access from the receiving terminal 21 (step S201: YES), the process proceeds to step S202, and the mass command device 11 determines whether the number of connections of the receiving terminal 21 has reached the limit number.

[0100] If the number of connections of the receiving terminal 21 has reached the limit number (step S202: NO), the process proceeds to step S203, and the mass command device 11 rejects the connection with this receiving terminal 21 and notifies the error to the receiving terminal 21.

[0101] If the number of connections of the receiving terminal 21 has not reached the limit number (step S202: YES), the process proceeds to step S204, and the mass command device 11 accepts the connection with this receiving terminal 21 and provides the HTML file for the operation screen to the receiving terminal 21.

[0102] In step S205, after providing the HTML file for the operation screen, the mass command device 11 determines whether there is an instruction for mass distribution from the receiving terminal 21.

[0103] When receiving an instruction for mass distribution from the receiving terminal 21 (step S205: YES), the process proceeds to step S206, and the mass command device 11 determines whether another mass distribution is being executed.

[0104] If another mass distribution is being executed (step S206: YES), the process proceeds to step S207, and the mass command device 11 buffers the specified contents of the distribution destination and the distribution target. That is, the mass command device 11 holds the execution of the instructed mass distribution.

[0105] If it is in the standby state where no mass distribution is being executed (step S206: NO), the process proceeds to step S208, and the mass command device 11 executes the instructed mass distribution based on the specified distribution destination and distribution target.

[0106] In step S209, when executing the mass distribution, the mass command device 11 notifies the distribution result to the receiving terminal 21.

[0107] When the mass instruction device 11 has not received an access from the receiving terminal 21 (step S201: NO), or when it has not received an instruction for mass distribution from the receiving terminal 21 (step S205: NO), it proceeds to step S210, executes mass distribution, notifies the receiving terminal 21 of the distribution result, and then determines whether there is an instruction for mass distribution buffered.

[0108] When there is an instruction for mass distribution buffered (step S210: YES), it proceeds to step S211, and the mass instruction device 11 extracts the instruction for mass distribution from the buffer (database 114). When there are multiple buffered instructions for mass distribution, the one with the highest priority among them is extracted. Alternatively, although the priority is low, there is also a possibility that the one whose elapsed time since buffering exceeds the threshold is extracted.

[0109] In step S212, the mass instruction device 11 executes mass distribution based on the specified distribution destination and distribution target of the instruction for mass distribution extracted from the buffer.

[0110] In step S213, when mass distribution is executed, the mass instruction device 11 notifies the receiving terminal 21 of the distribution result.

[0111] Note that the operations in the flowchart of FIG. 11 are cyclically executed by the mass instruction device 11. Therefore, for example, the instruction for mass distribution that was not extracted in step S211 and remained in the buffer will be an option to be extracted from the buffer by the mass instruction device 11 at a later timing when it has not received an access from the receiving terminal 21 (step S201: NO), or when it has not received an instruction for mass distribution from the receiving terminal 21 (step S205: NO), or after it has executed mass distribution and notified the receiving terminal 21 of the distribution result.

[0112] As described above, in the in-prefecture simultaneous command system 1 of the embodiment, the simultaneous command device 11 receives a remote operation from the receiving terminal 21 through communication conforming to, for example, the HTTPS protocol applied to communication via the Internet in a cloud system. Thereby, the in-prefecture simultaneous command system 1 of the embodiment can utilize the in-prefecture simultaneous command system 1 as a local information sharing means by a remote operation from the receiving terminal 21. In addition, the in-prefecture simultaneous command system 1 of the embodiment provides an interface for the receiving terminal 21 to remotely operate the simultaneous command device 11, which is suitable for a narrow-bandwidth wired line 53.

These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
