前記センサから出力される信号を無線送信可能な信号に変換する変換装置と、
前記変換装置によって変換された信号を無線送信する無線送信装置と、
前記無線送信装置から送信された信号を中継する中継装置と、
前記無線送信装置から送信された信号および前記中継装置によって中継された信号の一方または両方を受信する受信装置とを備え、
前記変換装置および無線送信装置は、前記熱電発電装置によって発電された電力によって駆動される、製鉄所設備用測定システム。
上記1~4のいずれか一項に記載の製鉄所設備用測定システムを用いて前記コークス炉の温度を測定する、コークス製造方法。
以下、本発明の第1の実施形態における測定システムについて説明する。なお、以下の説明において、「製鉄所設備用測定システム」を単に「測定システム」という場合がある。
(1)熱電発電装置
(2)センサ
(3)前記センサから出力される信号を無線送信可能な信号に変換する変換装置
(4)前記変換装置によって変換された信号を無線送信する無線送信装置
(5)前記無線送信装置から送信された信号を中継する中継装置
(6)前記無線送信装置から送信された信号および前記中継装置によって中継された信号の一方または両方を受信する受信装置
熱電発電装置は、該熱電発電装置の一方の側(高温側)と他方の側(低温側)との間の温度差を利用して発電することができる装置であり、一般的には、p型半導体とn型半導体を組み合わせた熱電素子を備えている。
前記センサとしては、とくに限定されることなく測定対象に応じて任意のセンサを用いることができる。前記センサとしては、例えば、温度センサ、圧力センサ、流量センサ、振動センサ、加速度センサからなる群より選択される少なくとも1つを用いることができる。前記温度センサとしては、例えば、熱電対、測温抵抗体、サーミスタなどが挙げられる。
前記センサから出力される信号は、変換装置によって無線送信可能な信号に変換される。前記変換装置としては、特に限定されることなく、市販の変換器等、任意の装置を用いることができる。
前記変換装置によって変換された信号は、無線送信装置により無線送信される。前記無線送信装置としては、特に限定されることなく、市販の装置等、信号を送信できるものであれば任意の装置を用いることができる。
本発明の製鉄所設備用測定システムは、上記変換装置および無線送信装置の一方または両方を冷却するための放熱部材を備えることが好ましい。上述したように、製鉄所の設備は高温である場合が多い。そこで、放熱部材を用いることにより、変換装置および無線送信装置の温度上昇を抑制することができる。前記放熱部材としては、例えば、放熱フィンなどを用いることができる。
また、本発明の製鉄所設備用測定システムは、直射日光を遮るための遮光部材を備えることが好ましい。例えば、コークス炉の上部など、屋外に測定システムを設置する場合、直射日光による装置温度の上昇が問題となる場合がある。そこで、遮光部材を用いて日光を遮ることによって温度上昇を抑制することができる。前記遮光部材は、熱電発電装置、変換装置、および無線送信装置の少なくとも1つへの直射日光を遮るよう構成されることが好ましい。例えば、熱電発電装置、変換装置、および無線送信装置を1つのパッケージ(熱電-無線送信ユニット)に実装する場合、当該熱電-無線送信ユニットに遮光部材を設けることで、熱電発電装置、変換装置、および無線送信装置の温度上昇を抑制することができる。
本発明の測定システムは、前記無線送信装置から送信された信号を中継する中継装置をさらに備えている。これにより、センサを設置した場所から離れた位置においても安定して信号を受信することができる。前記中継手段としては、とくに限定されることなく、無線送信装置から送信された信号を中継できるものであれば任意のものを用いることができる。
前記中継装置によって中継された信号は受信装置により受信される。なお、無線送信装置から送信された信号は、基本的には中継装置によって中継されるが、必ずしも中継装置で中継する必要は無く、例えば、受信装置に近い位置に設置された無線送信装置からの信号などについては中継装置を介さずに、直接受信装置で受信することもできる。したがって、前記受信装置は、前記無線送信装置から送信された信号および前記中継装置によって中継された信号の一方または両方を受信するよう構成される。前記受信装置としては、とくに限定されることなく、市販の受信装置等、信号を受信できるものであれば任意の装置を用いることができる。
次に、本発明の第2の実施形態における測定システムについて説明する。なお、特に言及しない点については上記第1の実施形態と同様とすることができる。
