針對現有輸送帶縱向撕裂監測系統存在監測點少、擴展性差、仍需人員值守等缺陷,設計了一種適用於多點監測和基於雲技術的輸送帶縱向撕裂遠程監測系統,該系統由一字線雷射器、嵌入式處理終端、面陣CMOS攝像頭、雲伺服器、PC機監測軟體和手機監測軟體組成。嵌入式處理終端驅動面陣CMOS攝像頭採集雷射器投射到輸送帶下表面的雷射條紋,並對採集到的每幀圖像進行分析,提取雷射條紋骨架,計算出畸變值。當畸變值大於預先設置的閾值時,表明輸送帶出現了縱向撕裂,嵌入式處理終端驅動報警器語音報警;當畸變值小於閾值時,表明輸送帶工作正常。嵌入式處理終端通過文件傳輸協議將圖像傳送給PC機並保存至本地。PC機監測軟體使用安全文件傳輸協議將接收到的圖像信息發送至雲伺服器,手機監測軟體利用Tomcat提供的Web伺服器訪問雲伺服器,實時獲取圖像信息。實驗結果表明:該系統實現了現場、PC端、手機端全方位的輸送帶縱向撕裂遠程實時監測,可隨時隨地監測任一監測點輸送帶的運行狀況。

The system consists of a word line laser, embedded processing terminal, area array CMOS camera, cloud server, PC monitoring software and mobile phone monitoring software.The embedded processing terminal drives area array CMOS camera to collect laser fringe projected by the laser onto lower surface of the conveyor belt, and analyzes each frame of collected image, extracts the laser fringe skeleton, and calculates the distortion value.When the distortion value is greater than the preset threshold value, it indicates that the conveyor belt has longitudinal tear and the embedded processing terminal drives the alarm with voice alarm.When the distortion value is less than the threshold value, it indicates that the conveyor belt works normally.The embedded processing terminal transfers image to PC via file transfer protocol and saves it locally.PC monitoring software uses secure file transfer protocol to send the received image information to the cloud server. Mobile phone monitoring software uses the Web server provided by Tomcat to access the cloud server and obtain the image information in real time.The experimental results show that the system can realize a full range of remote real -time monitoring of longitudinal tearing of conveyor belts on site, PC terminal and mobile terminal, and can monitor the running condition of the conveyor belt at any monitoring point in anytime and at anywhere.
