Description
本実施形態の説明に必要な用語を定義しておく。ここで車上制御装置を構成する電子回路を収容するサブラックとは、標準規格を指向したプリント基板(PCBs、以下「回路基板」又は単に「基板」ともいう)の収納具であり、一般的に金属性の筐体やフレームをいう。この収納具は、図3、図4、図7~図10に示すサブラック101のほか、カードケージ、ハウジング、ケース、キャビネット、シャーシ、又は単にラックとも呼ばれる。また、図1A~図4、図8~図10に示した集合体31~35(まとめて30)とは、車上制御装置を構成する電子回路であり、サブラック101を始めとする収納具に収納される全部をいう。
(2)回路基板の相互接続はバックボードで行うため、結合機構を形成するコネクタの種類を統一する。
(3)放熱のために回路基板は垂直に配置する。
鉄道列車用の車上制御装置12(図2)は、システムを構成する形態として、電子回路を実装した基板群とそれらを格納するサブラック101(図3~図4、及び図7~図10)の単位で構成することが一般的である。この場合、基板上の電子回路、及び各素子間を接続する信号線と、バス等に用いられる内部電源と、車両や他機器へのインターフェースに用いられる外部の電源と、は明確に区別される。一般的に、電子回路に使用される内部電源には低電圧が適用され、車両を駆動させるための電源や車両間の引き通し線等に使用される外部電源には高電圧が適用される、という区別は重要である。
以下、本発明の実施形態に係る車上制御システムについて、各図の順に詳細な説明する。図1Aは、本発明の実施形態に係る車上制御装置12Aの基板配置を示すブロック図であり、左右対称の配置例である。図1Aに示すように、車上制御装置12の構成要素は、制御部1系及び制御部2系の各系統の基板が左右対称に配置され、共通部16(図2)は中央に配置され、集合体31を形成する。
[1]この車上制御装置12は、冗長系統を形成する複数系統の制御部10,20がそれぞれの演算結果で相互補完するフェイルセーフ演算器102,202を備えている。フェイルセーフ演算器102,202が配設された制御部10,20は、演算基板17,27と、出力基板18,28と、共通部16と、を備える。
