【発明の属する技術分野】
本発明は、通信機器等を収納するラック内の温度を温度センサによって検出し、ネットワークを介して遠隔で監視を行うネットワーク環境監視装置に関する。
【0002】
【従来の技術】
従来、通信機器等を収納するラック内の温度を温度センサによって検出し、ネットワークを介して遠隔で監視を行うネットワーク環境監視装置は、温度に応じた電圧を出力するアナログ出力の温度センサが用いられていた(例えば、非特許文献1参照。)。

【0004】
【発明が解決しようとする課題】
アナログ出力の温度センサはネットワーク環境監視装置のアナログ入力ポートに1つずつしか接続できず、ネットワーク環境監視装置に設けられるアナログ入力ポートの数にはスペース的に限界があるため、必要な数の温度センサを接続できないことがあった。而もアナログ入力ポートに多数の配線がされるので配線が煩雑になっていた。また、ネットワーク環境監視装置と温度センサとの距離が長くなると、電圧降下で誤差が大きくなったり、ノイズによる影響を受けることがあるため、精度が低下するので配線距離を長くできなかった。ノイズの影響を受けにくくするためには高価なシールド線を使用しなければならなかった。更にネットワーク環境監視装置内でAD変換するため、誤差が生じる原因になっていた。
【0005】
そこで上記問題点に鑑み、本発明の目的は、1つのポートで多数の温度センサを接続することができて配線が煩雑にならず、配線距離が長くても電圧降下やノイズの影響を受けにくく、データの精度が高く、配線の全体の長さを短くでき、コストを低減することができるネットワーク環境監視装置を提供することである。

請求項1に記載の発明によれば、通信機器等を収納するラック内の温度を温度センサによって検出し、ネットワークを介して遠隔で監視を行うネットワーク環境監視装置において、デジタル出力の温度センサを用いたことにより、配線距離が長くても電圧降下やノイズの影響を受けにくく、且つ装置内でAD変換する必要がないので、データの精度が高く、シールド線を使う必要がないのでコストを低減することができる。
【0009】
請求項2に記載の発明によれば、請求項1に記載のネットワーク環境監視装置において、個別に識別IDを有する複数の温度センサを渡り配線して接続することにより、1つのポートで多数の温度センサを接続することができて配線が煩雑にならず、配線の全体の長さを短くできるので配線の手間が少ないと共に、コストを低減することができる。
【0010】
【実施例】
本発明に係るネットワーク環境監視装置の実施例を図1の添付図面に基づいて説明する。

【0012】
ネットワーク環境監視装置1に接続する温度センサ2は個別に識別IDを有するものであって、デジタル出力のものを用いる。
【0013】
温度センサ2とネットワーク環境監視装置1とは2本の電線3で接続し、温度センサ2と別の温度センサ2を渡り配線して複数の温度センサ2を接続する。このように接続することでネットワーク環境監視装置1には1つのポート1aを備えるだけで、多数の温度センサ2を接続することができる。温度センサ2で測定された温度はデジタル信号化されて電線3を通してネットワーク環境監視装置1に送信される。温度センサ2は識別IDを持っているので、他の温度センサ2の測定データと識別できるようになっている。
