Abstract
Description
以下本発明を実施の形態1に係る伸張度測定システムを示す図面に基づいて詳述する。図1はチェーンを略示する分解図である。
図中80は内リンクであり、内リンク80は、互いに対向する二つの内プレート81、81を備える。内プレート81は長円形の平板部材からなり、該平板部材の両端部に2つの穴を開設してある。一方の内プレート81の二つの穴に、円筒状の二つのブシュ82、82の一端部をしまりばめし、他方の内プレート81の二つの穴に、ブシュ82、82の他端部をしまりばめして、二つの内プレート81、81を連結している。各ブシュ82、82には環状のローラ85、85が回転自在に外嵌してある。
チェーン10は、図示しないスプロケットに掛け廻してある。チェーン10は、スプロケットの駆動によって図2の矢符にて示す方向に移動している。なおピン72の端部は外プレート71から適長突出しており、突出したピン72の端部には、チェーン10を撮像した場合にピン72と周囲とを識別することができるように、塗料が塗布してある。作業者は、チェーン10を端末装置(伸張度測定装置)20にて撮像する。
三つ以上並んだピン72、72、・・・、72を含むようにチェーン10を撮像し、撮像したチェーン10の画像を二値化する。そして、隣り合う三つのピン72、72、・・・、72の位置を抽出し、ピン間の画素数を求め、ピン間距離P1及びP2を求める(図5参照)。なお前述したようにピン72の端部には、ピン72と周囲と識別するための塗料が塗布してあり、ピン72の位置の抽出は確実に行われる。
{(P2-P1)/P1}・100・・・・(a)
{(P1・α-P2・β)/P2・β}・100・・・・(b)
またP1・α及びP3・γが外リンク71のピッチであり、P2・βが内リンク81のピッチである場合には、以下の(c)式によってチェーン10の伸張度が求められる。
{(P2・β-P1・α)/P1・α}・100・・・・(c)
なお上記(b)式、(c)式におけるP1・αはP3・γに置換することができる。
図6は、端末装置20のCPU21による第1方法に基づいた伸張度算出処理を説明するフローチャートである。
端末装置20のCPU21は、操作部27の操作によって伸張度算出処理の開始を示す信号が入力されたか否かを判定し(ステップS11)、伸張度算出処理の開始を示す信号が入力されるまで待機する(ステップS11:NO)。伸張度算出処理の開始を示す信号が入力された場合(ステップS11:YES)、端末装置20のCPU21は、撮像部24から撮像データが入力されたか否かを判定し(ステップS12)、撮像データが入力されるまで待機する(ステップS12:NO)。撮像部24から撮像データが入力された場合(ステップS12:YES)、端末装置20のCPU21は、撮像した画像を二値化し(ステップS13)、連続する四つのピンの位置を抽出してピン間距離P1、P2及びP3を算出する(ステップS14)。
以下本発明を実施の形態2に係る伸張度測定システムを示す図面に基づいて詳述する。実施の形態2に係る伸張度測定システムにあっては、端末装置20はチェーン10の撮像データを撮像位置及び撮像時刻と共にサーバ40に送信する。そしてサーバ40にてチェーンの伸張度を算出し、算出した伸張度を端末装置20に返信して、端末装置20の表示部26に伸張度を表示する。
サーバ40のCPU41は、端末装置20から撮像データ、撮像時刻及び撮像位置を受信したか否かを判定し(ステップS51)、撮像データ、撮像時刻及び撮像位置を受信するまで待機する(ステップS51:NO)。撮像データ、撮像時刻及び撮像位置を受信した場合(ステップS51:YES)、サーバ40のCPU41は、受信した撮像位置が既に識別テーブルに記憶されているか否かを判定する(ステップS52)。受信した撮像位置が識別テーブルに記憶されていない場合(ステップS52:NO)、サーバ40のCPU41は、チェーンIDなどを入力する指示を端末装置20に送信する(ステップS53)。なお受信した撮像位置が識別テーブルに記憶されていない場合、チェーンID、ユーザ名、納入先及び送付先アドレス(以下チェーンIDなどという)は識別テーブルに記憶されていない。
