Description
更に受電型情報発信装置10は、受電部14が得た電力を整流する整流手段を有してもよい。
なお、上述の実施形態においては、受電型情報発信装置を搭載したボルトを、軌条を固定する箇所に適用したが、勿論これに限定されるものではなく、例えば継目板の固定に適用するボルトとしてもよい等、その適用する箇所は適宜設定し得る。勿論、受電型情報発信装置が設けられる計測対象である長尺体としては、ボルトのようなねじ締結部材のみならず、軌条のような長尺体を計測対象として、直接的にひずみ計測手段や温度計測手段等の情報取得手段を設ける構成としてもよいことは言うまでもない。
このとき、円柱部44bの外周面に直接形成したひずみ計測センサ16aと受電型情報発信装置10とを接続する配線54は、円柱部44bの外周面、頭部42の座面、外周面及び頂面に沿わせて配設する。このような円柱部44b及び頭部42に沿って配線54を配する場合、配線54がボルト40を締結する時に被締結部材と接触して断線する虞があるので、配線54の経路に沿うように、円柱部44bの外周面、頭部42の座面、外周面及び頂面にかけて一連で断面凹状を成す配設路52を設けることが好ましい。
