Abstract

我々はICT機器の配線の削減による低CO_2化を目指して,メカトロニクスICT機器内に多数配置されているセンサと制御ボードを接続しているハーネス(線材)を,P-MP(Point to Multi-Point)の無線通信に置換する技術の研究開発を進めている.そこで,センサが内蔵されている4種類のICT機器(ATM,券売機,自動販売機,プリンタ)の内部の構造,ノイズ特性,電波伝搬特性を測定した.その結果,ICT機器内の狭空間における電波伝搬は,伝搬領域を見通し内・境界・見通し外に区分でき,伝搬損失の周波数依存性が比較的低いことがわかった.

We conduct research and development to replace the wire harness in the ICT equipments with wireless communication technology to reduce CO2 emissions during their lifecycle. In this report, the internal radio noise level and propagation characteristics are measured and investigated in four kinds of ICT equipments(ATM, ticket vendor, vending machine, and printer). As a result, the radio propagation in the ICT equipments are divided into three propagation sectors, such as line of sight, boundary, non line of sight. It was also found that frequency dependence of the propagation loss was comparatively low.
