Description

本発明は、波浪情報を収集、処理及び利用するためのシステムに関する。  The present invention relates to a system for collecting, processing and using wave information.

波高、波向及び潮位といった海象データは、港湾構造物及び海洋構造物の設計及び管理になくてはならないデータである。さらに、高潮対策及び津波対策といった防災の観点からも必要なデータである。これらのデータは、観測拠点に設置された海象計、波高計、波向計及び潮位計により測得される。測得されたデータの解析処理は、現地でそれぞれ個別に処理することも可能であるが、データの信頼性の確保、統計的データとしての蓄積の必要性及び広く当事者以外へのデータの提供の観点から、観測拠点における解析処理とともに、全国に展開された観測拠点のデータを、一括収集し、解析処理することが必要になる。  Sea state data such as wave height, wave direction, and tide level are indispensable for designing and managing harbor structures and marine structures. Furthermore, it is necessary data from the viewpoint of disaster prevention such as measures against storm surges and tsunami. These data are measured by the oceanographic, wave height, wave direction and tide gauges installed at the observation base. The analysis processing of the measured data can be performed individually on site, but it is necessary to ensure the reliability of the data, to store it as statistical data, and to provide the data to parties other than the parties widely. From the viewpoint, it is necessary to collect and analyze the data of observation bases deployed nationwide together with the analysis processing at the observation bases.

全国に展開された観測拠点のデータの一括収集及び解析処理のため、測得されたデータは、モデム又はルータを経由して、一定時間毎に一定の時間分のデータが間欠的にセンターに設置されたサーバーへ転送され、このサーバーに蓄積されたデータを基に解析処理が行われる。このデータ転送はこれまで、一般加入者回線やＩＳＤＮ回線を利用して行われてきたが、転送能力、安全性及び秘匿性に問題があった。また、今後は港湾管理及び防災の観点からの利用が多くなることから、全国に展開された観測拠点とセンターに設置されたサーバーを常時接続し、連続的にデータを転送することが必要になる。この場合、これまでの一般加入者回線やＩＳＤＮ回線を利用した転送では、回線利用料が極端に高額になるため、リアルタイムでデータを転送することは極めて困難であった。  For collective collection and analysis of data at observation bases deployed nationwide, the measured data is intermittently installed at the center at regular intervals via a modem or router. Analysis processing is performed based on the data transferred to the server and stored in the server. Until now, this data transfer has been carried out using a general subscriber line or an ISDN line, but there are problems in transfer capability, safety and confidentiality. In addition, since the use from the viewpoint of harbor management and disaster prevention will increase in the future, it will be necessary to continuously connect the observation bases deployed throughout the country and the servers installed in the center to transfer data continuously. . In this case, in the transfer using the general subscriber line and the ISDN line so far, the line usage fee becomes extremely high, and it is extremely difficult to transfer the data in real time.

上述の課題を解決するために、全国に展開された観測拠点からセンターに設置されたデータ収録サーバーまでのデータの転送にインターネットを利用する。この場合、これまでの一般加入者回線やＩＳＤＮ回線を利用した転送に比べて、通信費用が低廉になる。また、データ収集の目的が港湾管理及び防災といった重要なものになることから、安全性及び秘匿性が強く求められる。このため、インターネットを利用しつつ、セキュリティを確保できるシステムを構築する。  In order to solve the above-mentioned problems, the Internet is used for transferring data from observation bases deployed nationwide to a data recording server installed in the center. In this case, the communication cost is lower than the conventional transfer using a general subscriber line or ISDN line. Moreover, since the purpose of data collection becomes important such as port management and disaster prevention, safety and confidentiality are strongly required. Therefore, a system that can ensure security while using the Internet is constructed.

様々な海象観測機器及び気象観測機器から出力されるデータを、インターネット波浪情報転送装置により、センターに転送することで、安全性及び秘匿性を確保しながら、通信費用が低廉なデータ転送システムの構築が可能になる。  Construction of a data transfer system with low communication costs while ensuring safety and confidentiality by transferring data output from various oceanographic and meteorological observation equipment to the center using the Internet wave information transfer device Is possible.

観測拠点に設置されている機器は、海象計、波高計、波向計及び潮位計といった海象観測機器に加えて、風向風速計等の気象観測機器も含むが、これらの観測機器から出力されるデータは、アナログデータとデジタルデータの双方があり、そのフォーマットも様々であり、これらのデータを個別に転送するのでは、効率的でない。このため、観測拠点からのデータの転送に際しては、個々の異なった観測機器からのデータを取り込み、連続した観測データを、一定時間毎に効率的な転送ができるような形式のファイルに再編集する機能を有するインターネット波浪情報転送装置及びルータを介して、センターに転送する。また、転送時のセキュリティを確保するため、インターネット上に仮想的なトンネルを設定して、ユーザ認証やデータ暗号化を実行することにより、あたかも専用線で構築されているかのようにセキュリティを確保した仮想閉域網を利用する。センターに転送されたデータは、ルータ及びファイヤーウォールを介してデータ収録サーバーに蓄積される。この蓄積されたデータを、データ処理システムで処理することにより、異常値の除去その他の解析処理が行われ、信頼性の高い統計処理データがデータ提供サーバーに蓄積される。  The equipment installed at the observation base includes sea state observation equipment such as sea state meters, wave height meters, wave direction meters and tide gauges, as well as meteorological observation equipments such as wind direction anemometers. The data includes both analog data and digital data, and the formats thereof are various. It is not efficient to transfer these data individually. For this reason, when transferring data from the observation base, import data from different observation devices, and re-edit the continuous observation data into a file that can be efficiently transferred at regular intervals. The information is transferred to the center via the Internet wave information transfer device and router having a function. In addition, in order to ensure security during transfer, a virtual tunnel was set up on the Internet, and user authentication and data encryption were performed to ensure security as if it were constructed with a dedicated line. Use a virtual closed network. The data transferred to the center is stored in the data recording server via the router and the firewall. The accumulated data is processed by the data processing system, whereby abnormal values are removed and other analysis processes are performed, and highly reliable statistical processing data is accumulated in the data providing server.

図１は、本発明の実施例である。１は、海象計、潮位計、風向風速計を設置した観測拠点、２は、波高計、波向計、潮位計を設置した観測拠点、３は、潮位計を設置した観測拠点をそれぞれ示す。上記は、接続可能な観測拠点における観測機器の組合せのうちの数例を示したものであって、これ以外の観測機器の組合せを持つ観測拠点の接続も可能である。４は、インターネット、５は、センターを示す。  FIG. 1 shows an embodiment of the present invention. Reference numeral 1 is an observation base where a sea level meter, a tide gauge and an anemometer are installed, 2 is an observation base where a wave height meter, a wave direction meter and a tide gauge are installed, and 3 is an observation base where a tide gauge is installed. The above shows several examples of combinations of observation equipments at connectable observation bases, and observation bases having combinations of other observation equipments can also be connected. 4 indicates the Internet and 5 indicates the center.

本発明により、全国に展開された観測拠点の海象データを、低廉な通信費用で常時、リアルタイムで、センターに転送することが可能になり、港湾構造物及び海洋構造物の設計及び管理になくてはならないデータであるばかりでなく、防災面にも寄与するところが大きい。このため、実際に利用される可能性は、非常に高い。  According to the present invention, it becomes possible to transfer the sea state data of observation bases deployed nationwide to the center at low cost and constantly in real time, which is not in the design and management of harbor structures and marine structures. It is not only important data but also contributes to disaster prevention. For this reason, the possibility of actual use is very high.
