Description
本発明は、配電線遠方監視制御システムに用いられる子局装置に関する。 The present invention relates to a slave station device used in a distribution line remote monitoring and control system.
複数の遠制方式（伝送方式）で構成されている配電線遠方監視制御システムにおいては、それぞれの遠制方式に対応した子局が存在する。
子局をある遠制方式から他の遠制方式に対応させるには、子局全体を取り替える必要があり、コストが高い。また、子局の種類が多いため、生産コストを低減することが困難である。 In order to change the slave station from one remote control system to another remote control system, it is necessary to replace the entire slave station, which is expensive. In addition, since there are many types of slave stations, it is difficult to reduce production costs.
上記課題を解決するため、本発明では、共通化可能な機能を抽出し、他の機能と独立した形態とした。また、独立した形態とするために、ハード、ソフトを共通化に対応した設計とした。非共通化部分であるモデム部を、インテリジェント化、およびインターフェース部分を共通化した。 In order to solve the above-described problems, in the present invention, functions that can be shared are extracted and made independent of other functions. In order to make it independent, the hardware and software are designed to be shared. The modem part, which is a non-common part, is made intelligent and the interface part is made common.
具体的には、配電線遠方監視制御システムに用いられる子局装置であって、複数の遠制方式において共通化可能な機能が抽出された共通化部分と、各遠制方式に応じて交換される個別専用部分とを有しており、前記共通化部分には、共通化子局ソフトとして機能するファームウェアソフトと、子局装置の運用に関する条件が定義される論理情報テーブルである情報管理テーブルとを備え、前記ファームウェアソフトは、子局装置の運用時に前記情報管理テーブルを参照するように設定されており、該情報管理テーブルは、前記各遠制方式に応じて交換されるように構成している。Specifically, it is a slave station device used in a distribution line remote monitoring control system, and is exchanged according to each distance control method with a common part from which functions that can be shared by a plurality of distance control methods are extracted. The common part includes firmware software that functions as common slave station software, an information management table that is a logical information table in which conditions relating to the operation of the slave station device are defined, And the firmware software is set to refer to the information management table during operation of the slave station device, and the information management table is configured to be exchanged according to each distance control method. Yes.
また、前記情報管理テーブルは、子局装置への入出力の情報が更新されるごとに、前記ファームウェアソフトから参照されて、子局装置の運用に関する条件が読み取られるように構成するのが望ましい。The information management table is preferably configured to be read from the firmware software and read conditions relating to the operation of the slave station device each time information on input / output to the slave station device is updated.
さらに、前記各遠制方式は、ＧＷ・ＴＰＣ方式、ＣＴＣ方式、及び光方式を備え、前記情報管理テーブルは、該ＧＷ・ＴＰＣ方式、ＣＴＣ方式、及び光方式に応じて交換されるように構成するのが望ましい。Further, each distance control method includes a GW / TPC method, a CTC method, and an optical method, and the information management table is configured to be exchanged according to the GW / TPC method, the CTC method, and the optical method. It is desirable to do.
本発明によれば、子局のモデム部分を独立した形態とし、ハード・ソフトの共通化に対応した設計としたため、対応するモデム部分を交換するだけで遠制方式を変更でき、コスト削減が図れる。 According to the present invention, the modem portion of the slave station is made an independent form and designed to be compatible with hardware and software, so that it is possible to change the distance control system simply by exchanging the corresponding modem portion, thereby reducing costs. .
配電線遠方監視制御（遠制）システムにおける子局の役割は、遠制運用で必要な情報である監視情報「Line Switchの開閉状態（入／切）情報」を親局に通知することと、親局との制御情報の交換を通して「Line Switchの投入／開放に関する遠制入／切、および、遠制ロック／ロック解除」を実行監視する機能が重要である。これらの必須情報はすべての子局が持ち合わせているが、子局種別ごとに伝達情報の中のポジションは異なっており、さらに、定義も少しずつ異なる。 The role of the slave station in the distribution line remote monitoring control (distance control) system is to notify the master station of monitoring information “Line Switch open / closed status (on / off) information”, which is information necessary for remote control operation, The function of executing and monitoring “distance on / off on line switch on / off and distance lock / unlock” through the exchange of control information with the master station is important. Although all the slave stations have such essential information, the position in the transmission information is different for each slave station type, and the definition is slightly different.
そこで本願発明者らは、各種別子局において共通と判断される機能についてその定義の共通化を図ることとした。具体的には、現在の主流・今後主流となる子局を対象に、各子局が作成する情報を一元化・包括する情報管理テーブルを定義し、子局内に一元化・包括された情報管理テーブルを持たせることで各子局の情報設定条件を共通化することを実現した。この共通化により、これらの情報を作成するために必要な情報源である、子局を構成するハードウェアの共通化も図ることが可能となった。本発明により子局の共通化を実現できた範囲を図１に示す。 Therefore, the inventors of the present application decided to share the definition of the function judged to be common among the various slave stations. Specifically, for the current mainstream and future mainstream slave stations, an information management table that unifies and includes information created by each slave station is defined, and a centralized and comprehensive information management table within the slave station By having it, it was realized to share information setting conditions of each slave station. This sharing makes it possible to share the hardware constituting the slave station, which is an information source necessary for creating such information. FIG. 1 shows a range in which the slave stations can be shared by the present invention.
子局は、定義の共通化により機能に関するハード・ソフトの共通化が実現され、図１に示すように共通項を持つに至った。しかしながら、過去から運用中のシステムであることから、伝送用のインフラが再利用される。したがって適合性を保証することが重要であり、そのためにモデム部分に差異を集めて対応することとした。共通化子局の概略構成を図２に示す。また、共通化子局における共有化実現部分および個別専用部分の説明を図３に示す。 The slave stations have shared hardware and software related functions by sharing definitions, and have common items as shown in FIG. However, since the system has been in operation since the past, the transmission infrastructure is reused. Therefore, it is important to guarantee compatibility, and for this purpose, we decided to collect differences in the modem part. FIG. 2 shows a schematic configuration of the common slave station. Further, FIG. 3 shows a description of the sharing realizing part and the individual dedicated part in the common slave station.
子局の共有化は、情報管理テーブルに動作仕様を定義し、運用する子局のアルゴリズムが確定したことにより実現された。情報管理テーブルとは、子局の運用に関する（動作・処置・判定）の条件を定義した、子局のファームウェアソフトが常に参照する論理情報テーブルである。論理情報テーブルは２次元テーブルで、子局の入出力データ（ここでは１６ビット構成）のビットごとに処理・判定条件が定義されている。子局は入出力の情報が更新されるごとに本テーブルを参照し処理・判定条件を読み取り実行する。この方式の採用により、運用中の子局を種別の異なる遠制システムにて運用する場合でも、情報管理テーブルを移行するターゲットシステムに適合した情報に置き換えることで運用できるようにした。情報管理テーブルは、共通仕様のハードウェア環境を持つメインＣＰＵボードであれば、メーカ管理ではあるが、差し替え・転用は簡単にかつ確実に行うことが可能となった。 Slave station sharing was realized by defining the operation specifications in the information management table and determining the algorithm of the slave station to be used. The information management table is a logical information table that defines the conditions (operation / treatment / determination) related to the operation of the slave station and is always referred to by the firmware software of the slave station. The logical information table is a two-dimensional table, and processing / judgment conditions are defined for each bit of the slave station input / output data (here, 16-bit configuration). Each time the input / output information is updated, the slave station refers to this table and reads and executes the processing / determination conditions. By adopting this method, even if the operating slave station is operated in a remote control system of a different type, it can be operated by replacing the information management table with information suitable for the target system to be migrated. As long as the information management table is a main CPU board having a hardware environment with a common specification, although it is manufacturer management, replacement and diversion can be performed easily and reliably.
本発明は、複数の遠制方式で構成されている配電線遠方監視制御システム等に利用可能である。 The present invention can be used for a distribution line remote monitoring and control system configured by a plurality of remote control systems.
