Description

情報分散型管理システムInformation distributed management system
　本発明は、情報分散型管理システムに関する。 The present invention relates to an information distributed management system.
　台風、大雪などの気象情報や地震、火山情報などの防災情報、その他の地域生活情報などを自治体からインターネットを介して利用者が使用するパーソナル・コンピュータ等のクライアント端末に周知させるシステムがある。このシステムは、住民一人一人の自主的な行動や相互扶助を促すために必要な情報の伝達と共有を図るようにしている。 There is a system for disseminating weather information such as typhoons and heavy snow, disaster prevention information such as earthquake and volcano information, and other local life information from local governments to client terminals such as personal computers used by users via the Internet. This system is designed to communicate and share the information necessary to promote the independent behavior and mutual assistance of each individual resident.
　一般的に、この種のシステムには、各自治体から住民へ情報提供する手段の１つとして、一般行政連絡を行う防災行政無線システムやメール配信を行う告知システムがある。これら防災行政無線システム及び告知システムは、主な目的として、県及び市町村が「地域防災計画」に基づき、それぞれの地域における防災、応急救助、災害復旧に関する業務に使用される。ところが、各種情報の多くが発信者側の一方的なものであり、利用者側にとっては地区地域が異なる等の理由により不必要な情報が配信される。また、防災行政無線システムなどでは、豪雨などの影響により屋外拡声器からの音声が聞こえづらい場合や聞き漏らし等により、各種自治体からの配信情報が住民等に伝わらないおそれがある。また、災害により通信回線が切断された場合に、各種自治体からの配信情報が住民等に伝わらない。 Generally, in this type of system, as one of means for providing information from local governments to residents, there are a disaster prevention administrative radio system that performs general administrative communication and a notification system that performs mail distribution. These disaster prevention administrative radio systems and notification systems are mainly used by the prefectures and municipalities for work related to disaster prevention, emergency rescue, and disaster recovery in their respective regions based on the “Regional Disaster Prevention Plan”. However, most of the various information is unilateral on the sender side, and unnecessary information is distributed to the user side for reasons such as different districts. In addition, in disaster prevention administrative radio systems and the like, there is a risk that distribution information from various local governments may not be transmitted to the residents, etc., due to the case where it is difficult to hear the sound from the outdoor loudspeaker due to the influence of heavy rain or the like. In addition, when a communication line is disconnected due to a disaster, distribution information from various local governments is not transmitted to residents.
　また、災害時等においては、キャリア回線網の輻輳等が予想され、一般的に主な情報入手手段となっているインターネットの使用が困難となる場合が想定される。そこで、Ｗｉ－Ｆｉ（登録商標）等の無線接続機器の設置使用用途が増えてきている。なお、Ｗｉ－Ｆｉの無線接続機器は、近距離無線システムの親機である。 Also, in the event of a disaster, it is expected that the carrier line network will be congested, making it difficult to use the Internet, which is generally the main means of obtaining information. In view of this, the use of wireless connection devices such as Wi-Fi (registered trademark) is increasing. The Wi-Fi wireless connection device is a base unit of the short-range wireless system.
　加えて、災害発生時などにおいては速やかに避難施設の開設等の対応が求められる中、限られた自治体関係者で当該地区の被災状況の確認等を行うことは困難である。このため、当該住民の方々からの広い情報投稿が求められることが想定される。 In addition, in the event of a disaster, etc., it is difficult to confirm the status of damage in the area by a limited number of local officials amidst the need to promptly establish evacuation facilities. For this reason, it is assumed that wide posting of information from the residents is required.
　災害状況によっては通信回線が遮断されてインターネット回線等が接続不可能となり、情報収集が不可能となる。このような場合に、自動的にＷｉ－Ｆｉアクセスポイント単位で特定エリア内において通信可能とするシステムが望まれる。 Depending on the disaster situation, the communication line is cut off and the Internet line cannot be connected, making it impossible to collect information. In such a case, a system that automatically enables communication within a specific area in units of Wi-Fi access points is desired.
　同報系の防災行政無線システムなどは、屋外拡声器や戸別受信機を介して市町村から住民等に対して直接または同時に防災情報や行政情報を伝えることを目的としている。同報系の防災行政無線システムから配信される情報は、特に災害時において人命に関わるものであることも多い。しかしながら、豪雨などの周辺環境の状態により屋外拡声器からの音声が聞こえづらい場合や聞き漏らし等が発生する。この場合、各種自治体からの配信情報が住民等に伝わらないおそれがあるため、住民に対する情報伝達手段の多様化が必須となっている。また、災害内容によっては通信回線が切断されて通信が不可能となる。 The broadcast disaster prevention administrative radio system, etc., aims to transmit disaster prevention information and administrative information directly or simultaneously from the municipality to residents through outdoor loudspeakers and door-to-door receivers. Information distributed from the broadcast disaster prevention administrative radio system is often related to human life, especially in the event of a disaster. However, the sound from the outdoor loudspeaker is difficult to hear or missed due to the surrounding environment such as heavy rain. In this case, since there is a possibility that distribution information from various local governments may not be transmitted to residents and the like, diversification of information transmission means for residents is indispensable. Also, depending on the nature of the disaster, the communication line is disconnected and communication becomes impossible.
　また、災害発生時等の錯綜した環境下において、限られた自治体関係者が地域の被災状況の把握を行うことは困難であると想定される。そこで、防災に関わる地域住民一人一人の自主的な行動や相互扶助を促すために、当該エリアの被災状況を住民自ら投稿発信できる仕組みが求められている。 Also, it is assumed that it is difficult for limited local government officials to grasp the local disaster situation in a complicated environment such as when a disaster occurs. Therefore, in order to promote the voluntary actions and mutual assistance of each local inhabitant related to disaster prevention, there is a need for a mechanism that allows residents to post and send information on the disaster situation in the area.
　本発明の目的は、通信回線が切断された場合やセンタ側の配信サーバが動作異常となった場合でも最低限の情報を共有することを可能とする情報分散型管理システムを提供することにある。 An object of the present invention is to provide an information distributed management system that enables sharing of minimum information even when a communication line is disconnected or when a distribution server on the center side malfunctions. .
　上記目的を達成するために本発明の観点は、以下のような構成要素を備えている。すなわち、複数の近距離無線システム用の基地局と、カメラ装置と、情報通信機器と、情報管理装置とを備える。複数の近距離無線システム用の基地局は、各々無線エリアを形成する。カメラ装置は、前記複数の近距離無線システム用の基地局にそれぞれ備えられ、前記無線エリア内の映像を撮像する。情報通信機器は、前記無線エリアに位置し、少なくとも１つの前記近距離無線システム用の基地局に対し無線回線を介して接続可能である。サーバ装置は、前記複数の近距離無線システム用の基地局に対し通信回線を介して接続され、前記カメラ装置が撮像したカメラ映像情報及び前記情報通信機器から送信される第１の情報を受信し、前記カメラ映像情報及び第２の情報を前記情報通信機器へ配信する。情報管理装置は、前記複数の近距離無線システム用の基地局にそれぞれ備えられ、少なくとも前記サーバ装置との間の通信状況を監視し、前記サーバ装置により収集された少なくとも前記カメラ映像情報及び前記第２の情報を含む収集情報を一時的に記憶する。 In order to achieve the above object, the aspect of the present invention includes the following components.

　配信サーバ３０６は、例えば観光・防災Ｗｉ－Ｆｉステーション１０２－１への撮像要求の送信時間Ｔ０になるか否かを監視している（ステップＳＴ１５ａ）。そして、送信時間Ｔ０になると（Ｙｅｓ）、配信サーバ３０６は観光・防災Ｗｉ－Ｆｉステーション１０２－１が形成する無線エリアに位置する情報通信機器１０４の利用者へ例えば「山の裾のアップを撮影してください。」という文字情報を含む撮像要求を送信する。送信後、所定時間経過した後に、配信サーバ３０６はカメラ映像情報を受信できたか否かの確認を行い（ステップＳＴ１５ｃ）。受信した場合に（Ｙｅｓ）、配信サーバ３０６はカメラ映像情報「山の裾のアップ」を観光・防災Ｗｉ－Ｆｉステーション１０２－１の基地局ＩＤ「ＢＳ１」及び情報通信機器１０４の端末ＩＤ「ＴＭ１」に関連付けてデータベース３０６２４に記憶する（ステップＳＴ１５ｄ）。 FIG. 15 is a flowchart showing the polling format operation of the distribution server 306.
For example, the distribution server 306 monitors whether or not the transmission time T0 of the imaging request to the sightseeing / disaster prevention Wi-Fi station 102-1 is reached (step ST15a). Then, when the transmission time T0 is reached (Yes), the distribution server 306 gives a photograph to the user of the information communication device 104 located in the wireless area formed by the sightseeing / disaster prevention Wi-Fi station 102-1, for example, Please send an imaging request including the text information. After a predetermined time elapses after transmission, the distribution server 306 confirms whether the camera video information has been received (step ST15c). When received (Yes), the distribution server 306 receives the camera image information “up of the foot of the mountain” as the base station ID “BS1” of the tourism / disaster prevention Wi-Fi station 102-1 and the terminal ID “TM1” of the information communication device 104.

Further, the distribution server 306 monitors, for example, whether or not the transmission time T1 of the imaging request to the sightseeing / disaster prevention Wi-Fi station 102-2 is reached. Then, when the transmission time T1 is reached, the distribution server 306 says to the user of the information communication device 104 located in the wireless area formed by the sightseeing / disaster prevention Wi-Fi station 102-2 “Please take a picture of the factory up”. An imaging request including character information is transmitted.
　ここで、配信サーバ３０６のオペレータは、データベース３０６２４を参照して、基地局ＩＤ「ＢＳ１」を選択指定したとする。すると、配信サーバ３０６は、基地局ＩＤ「ＢＳ１」に対応するカメラ映像情報及び投稿情報をデータベース３０６２４から読み出して、一覧表示情報、地図表示情報及び個別詳細表示情報を作成し、図１６に示すように、操作・表示用パーソナル・コンピュータ３０７に表示する。 Here, it is assumed that the operator of the distribution server 306 selects and designates the base station ID “BS1” with reference to the database 30624.

Are displayed on the operation / display personal computer 307.
　ここで、オペレータは、一覧表示１２０１のチェック欄にチェックを入力すると、地図表示１２０２上に、「土砂崩れ」、「道路陥没」、「大雨」、「火災」、「河川氾濫」の各アイコンが表示される。オペレータが「土砂崩れ」のアイコンにタッチすると、「土砂崩れ」に関する個別詳細表示１２０３が拡大表示される。 Here, when the operator inputs a check in the check field of the list display 1201, icons of “landslide”, “road collapse”, “heavy rain”, “fire”, and “river inundation” are displayed on the map display 1202. Is done. When the operator touches the “landslide” icon, an individual detail display 1203 regarding “landslide” is displayed in an enlarged manner.
　一方、配信サーバ３０６は、所定の配信処理を実行する際に、オペレータにより選択指定される無線エリアのカメラ映像情報及び観光情報に基づいて、一覧表示情報、地図表示情報、個別詳細表示情報を作成する。そして、配信サーバ３０６は、これら一覧表示情報、地図表示情報、個別詳細表示情報を要求のあった観光・防災Ｗｉ－Ｆｉステーション１０２－１の情報通信機器１０４へ配信して、図１７に示すように、一覧表示情報、地図表示情報、個別詳細表示情報を選択的に表示させる。 On the other hand, the distribution server 306 creates list display information, map display information, and individual detailed display information based on the camera image information and sightseeing information of the wireless area selected and designated by the operator when executing a predetermined distribution process. To do. Then, the distribution server 306 distributes the list display information, the map display information, and the individual detailed display information to the information communication device 104 of the requested sightseeing / disaster prevention Wi-Fi station 102-1, as shown in FIG. List display information, map display information, and individual detailed display information are selectively displayed.
　情報通信機器１０４の利用者は、一覧表示１３０１の観光・レジャー情報を選択し、「温泉」、「観光名所」、「ホテル・旅館」、「イベント情報」のチェック欄にチェックを入力したとする。すると、地図表示１３０２上に、「温泉」、「観光名所」、「ホテル・旅館」、「イベント情報」の各アイコンが表示される。このうち、「観光名所」のアイコンをタッチすると、「観光名所○桜公園」の個別詳細表示１３０３が拡大表示される。 It is assumed that the user of the information communication device 104 selects sightseeing / leisure information on the list display 1301 and inputs a check in the check boxes for “hot spring”, “tourist attraction”, “hotel / inn”, and “event information”. . Then, icons of “hot spring”, “tourist attraction”, “hotel / ryokan”, and “event information” are displayed on the map display 1302. Among these, when the “tourist attraction” icon is touched, the individual detailed display 1303 of “tourist attraction ○ Sakura Park” is enlarged.

　次に上記情報管理装置１０５の構成における動作について説明する。　
　（配信サーバ３０６が正常時の動作）　
　情報管理装置１０５は、無線エリア内の情報通信機器１０４に割り当てられる例えばＩＰ(Internet Protocol)アドレスといったアドレスの管理機能、配信サーバ３０６に割り当てられるアドレスの管理機能を有している。 Next, the operation in the configuration of the information management apparatus 105 will be described.
(Operation when distribution server 306 is normal)
The information management apparatus 105 has an address management function such as an IP (Internet Protocol) address assigned to the information communication device 104 in the wireless area and an address management function assigned to the distribution server 306.
　情報管理装置１０５は、図１８に示すように、配信サーバ３０６に対し応答要請を送信する（Ｓ１０１）。しかる後に、情報管理装置１０５は、配信サーバ３０６への通信確立要求信号に収集情報を取得するため要求情報、例えば「％００１０」を挿入し、この通信確立要求信号を配信サーバ３０６へ送信する（Ｓ１０２）。収集情報としては、カメラ映像、気象観測データ、市役所からのお知らせ、災害情報が含まれる。 The information management apparatus 105 transmits a response request to the distribution server 306 as shown in FIG. 18 (S101). After that, the information management apparatus 105 inserts request information, for example, “% 0010” in order to acquire the collected information into the communication establishment request signal to the distribution server 306, and transmits this communication establishment request signal to the distribution server 306 ( S102). The collected information includes camera images, weather observation data, news from the city hall, and disaster information.
　配信サーバ３０６は、通信確立要求信号を受信すると、情報管理装置１０５との間に通信路を形成し、この通信確立要求信号に要求情報が挿入されているか判定する。そして、要求情報である「％００１０」が挿入されていれば、配信サーバ３０６は、当該情報の内容に従い配信サーバ３０６のデータベース３０６２４を検索して収集情報を読み出し、この収集情報を要求元の情報管理装置１０５へ送信する（Ｓ１０３）。そして、この情報の送信を終了すると、配信サーバ３０６は「正常」の旨を示す通信解放信号を要求元の情報管理装置１０５へ送信する。 When the distribution server 306 receives the communication establishment request signal, the distribution server 306 forms a communication path with the information management apparatus 105 and determines whether the request information is inserted in the communication establishment request signal. If the request information “% 0010” is inserted, the distribution server 306 searches the database 30624 of the distribution server 306 according to the content of the information, reads the collected information, and uses the collected information as the request source information. It transmits to the management apparatus 105 (S103). When the transmission of this information is completed, the distribution server 306 transmits a communication release signal indicating “normal” to the requesting information management apparatus 105.
　情報管理装置１０５は、配信サーバ３０６から収集情報を受信すると、この収集情報を情報管理装置１０５のデータベース１０５３２に記憶する（Ｓ１０４）。 When the information management apparatus 105 receives the collected information from the distribution server 306, the information management apparatus 105 stores the collected information in the database 10532 of the information management apparatus 105 (S104).
　一方、情報管理装置１０５は、電源投入時や再起動時（システム復帰後）に、配信サーバ３０６に対し応答要請を送信し（Ｓ１０５）、配信サーバ３０６からの応答を受信する（Ｓ１０６）。そして、情報管理装置１０５は、配信サーバ３０６への通信確立要求信号に収集情報を取得するための要求情報、例えば「％００１０」を挿入し、この通信確立要求信号を配信サーバ３０６へ送信する（Ｓ１０７）。 On the other hand, the information management apparatus 105 transmits a response request to the distribution server 306 at power-on or restart (after system recovery) (S105), and receives a response from the distribution server 306 (S106). Then, the information management apparatus 105 inserts request information for acquiring collected information, for example, “% 0010” into the communication establishment request signal to the distribution server 306 and transmits this communication establishment request signal to the distribution server 306 ( S107).
　配信サーバ３０６は、通信確立要求信号を受信すると、情報管理装置１０５との間に通信路を形成し、この通信確立要求信号に要求情報が挿入されているか判定する。そして、要求情報である「％００１０」が挿入されていれば、当該情報の内容に従いデータベース３０６２４を検索して収集情報を読み出し、この収集情報を要求元の情報管理装置１０５へ送信する（Ｓ１０８）。 When the distribution server 306 receives the communication establishment request signal, the distribution server 306 forms a communication path with the information management apparatus 105 and determines whether the request information is inserted in the communication establishment request signal. If the request information “% 0010” is inserted, the database 30624 is searched according to the content of the information, the collected information is read, and the collected information is transmitted to the requesting information management apparatus 105 (S108). .
　情報管理装置１０５は、配信サーバ３０６から収集情報を受信すると、この収集情報をデータベース１０５３２に記憶する（Ｓ１０９）。 When the information management apparatus 105 receives the collected information from the distribution server 306, the information management apparatus 105 stores the collected information in the database 10532 (S109).
　データベース１０５３２に収集情報を記憶してから一定時間経過した後、情報管理装置１０５はデータベース１０５３２に記憶された収集情報を読み出して配信サーバ３０６へ送信し（Ｓ１１０）、データベース１０５３２に記憶された収集情報を破棄する（Ｓ１１１）。一方、配信サーバ３０６は、情報管理装置１０５から送られた収集情報を受信すると、この収集情報をデータベース３０６２４に記憶する（Ｓ１１２）。 After a certain period of time has elapsed since the collection information was stored in the database 10532, the information management apparatus 105 reads the collection information stored in the database 10532 and transmits it to the distribution server 306 (S110), and the collection information stored in the database 10532 Is discarded (S111). On the other hand, when the distribution server 306 receives the collection information sent from the information management apparatus 105, the distribution server 306 stores the collection information in the database 30624 (S112).
　（情報通信機器１０４と配信サーバ３０６との間の情報の送受信）　
　情報通信機器１０４の利用者が、カメラ映像情報を取得する操作を行ったとする。この場合、情報通信機器１０４は、配信サーバ３０６への通信確立要求信号に、カメラ映像情報を取得するための要求情報、例えば「％０００１」を挿入し、この通信確立要求信号を情報管理装置１０５へ送信する（Ｓ１１３）。 (Transmission and reception of information between the information communication device 104 and the distribution server 306)
It is assumed that the user of the information communication device 104 performs an operation for acquiring camera video information. In this case, the information communication device 104 inserts request information for acquiring camera video information, for example “% 0001”, into the communication establishment request signal to the distribution server 306, and uses this communication establishment request signal as the information management apparatus 105. (S113).
　情報管理装置１０５は、通信確立要求信号を受信すると、この通信確立要求信号を配信サーバ３０６へ送信する（Ｓ１１４）。 When the information management apparatus 105 receives the communication establishment request signal, the information management apparatus 105 transmits the communication establishment request signal to the distribution server 306 (S114).
　配信サーバ３０６は、通信確立要求信号を受信すると、この通信確立要求信号に要求情報が挿入されているかを判定する。そして、要求情報である「％０００１」が挿入されていれば、当該情報の内容に従いデータベース３０６２４を検索してカメラ映像情報を読み出し、このカメラ映像情報を情報通信機器１０４へ送信する（Ｓ１１５）。この情報の送信を終了すると、配信サーバ３０６は「正常」の旨を示す通信解放信号を要求元の情報通信機器１０４へ送信する。 When the distribution server 306 receives the communication establishment request signal, the distribution server 306 determines whether request information is inserted in the communication establishment request signal. If the request information “% 0001” is inserted, the database 30624 is searched according to the content of the information to read the camera video information, and the camera video information is transmitted to the information communication device 104 (S115). When the transmission of this information is completed, the distribution server 306 transmits a communication release signal indicating “normal” to the requesting information communication device 104.
　（情報通信機器１０４から配信サーバ３０６への情報の送信）　
　情報通信機器１０４の利用者が、投稿情報を送信する操作を行ったとする。この場合、情報通信機器１０４は、配信サーバ３０６への通信確立要求信号に、投稿情報及び投稿情報を送信するための要求情報、例えば「％０１０１」を挿入し、この通信確立要求信号を情報管理装置１０５へ送信する（Ｓ１１６）。 (Transmission of information from information communication device 104 to distribution server 306)
It is assumed that the user of the information communication device 104 performs an operation for transmitting post information. In this case, the information communication device 104 inserts post information and request information for transmitting the post information, for example, “% 0101” into the communication establishment request signal to the distribution server 306, and manages the communication establishment request signal with the information management. It transmits to the apparatus 105 (S116).
　情報管理装置１０５は、通信確立要求信号を受信すると、この通信確立要求信号を配信サーバ３０６へ送信する（Ｓ１１７）。 When the information management apparatus 105 receives the communication establishment request signal, the information management apparatus 105 transmits the communication establishment request signal to the distribution server 306 (S117).
　配信サーバ３０６は、通信確立要求信号を受信すると、この通信確立要求信号に要求情報が挿入されているかを判定する。そして、要求情報である「％０１０１」が挿入されていれば、配信サーバ３０６は、通信確立要求信号に含まれる投稿情報をデータベース３０６２４に記憶する（Ｓ１１８）。この投稿情報の記憶を終了すると、配信サーバ３０６は、「正常」の旨を示す通信解放信号を要求元の情報通信機器１０４へ送信する。 When the distribution server 306 receives the communication establishment request signal, the distribution server 306 determines whether request information is inserted in the communication establishment request signal. If the request information “% 0101” is inserted, the distribution server 306 stores the posting information included in the communication establishment request signal in the database 30624 (S118). When the post information storage is completed, the distribution server 306 transmits a communication release signal indicating “normal” to the requesting information communication device 104.
　（配信サーバ３０６の障害発生）　
　情報管理装置１０５では、配信サーバ３０６の障害監視が行われる。さて、この状態で、配信サーバ３０６において、例えばオペレーティングシステムやプログラムが暴走すると、情報管理装置１０５が例えば周期的に監視信号を送信しても、配信サーバ３０６は応答信号を送信しない。また、配信サーバ３０６との間の通信回線が切断されると、情報管理装置１５は、配信サーバ３０６からの信号を受信できない。 (Distribution server 306 failure)
In the information management apparatus 105, the failure monitoring of the distribution server 306 is performed. In this state, if, for example, an operating system or a program runs out of control in the distribution server 306, the distribution server 306 does not transmit a response signal even if the information management apparatus 105 periodically transmits a monitoring signal. In addition, when the communication line with the distribution server 306 is disconnected, the information management apparatus 15 cannot receive a signal from the distribution server 306.
　この場合、情報管理装置１０５は、監視信号の送信後、一定時間が経過した時点で、応答信号が到来しないことから、配信サーバ３０６との間の通信障害が発生したと判断する。なお、配信サーバ３０６側では、オペレータにより観光・防災Ｗｉ－Ｆｉステーション１０２－１～１０２－ｎとの切り離しが行われる（Ｓ１１９）。 In this case, the information management apparatus 105 determines that a communication failure with the distribution server 306 has occurred because a response signal does not arrive when a certain time has elapsed after transmission of the monitoring signal. On the distribution server 306 side, the operator disconnects the sightseeing / disaster prevention Wi-Fi stations 102-1 to 102-n (S119).
