摘　　要：针对现有输送带纵向撕裂监测系统存在监测点少、扩展性差、仍需人员值守等缺陷,设计了一种适用于多点监测和基于云技术的输送带纵向撕裂远程监测系统,该系统由一字线激光器、嵌入式处理终端、面阵CMOS摄像头、云服务器、PC机监测软件和手机监测软件组成。嵌入式处理终端驱动面阵CMOS摄像头采集激光器投射到输送带下表面的激光条纹,并对采集到的每帧图像进行分析,提取激光条纹骨架,计算出畸变值。当畸变值大于预先设置的阈值时,表明输送带出现了纵向撕裂,嵌入式处理终端驱动报警器语音报警;当畸变值小于阈值时,表明输送带工作正常。嵌入式处理终端通过文件传输协议将图像传送给PC机并保存至本地。PC机监测软件使用安全文件传输协议将接收到的图像信息发送至云服务器,手机监测软件利用Tomcat提供的Web服务器访问云服务器,实时获取图像信息。实验结果表明:该系统实现了现场、PC端、手机端全方位的输送带纵向撕裂远程实时监测,可随时随地监测任一监测点输送带的运行状况。In view of the defects of existing longitudinal tearing monitoring system of conveyor belt,such as few monitoring points,poor expansibility,and still need to be on duty,a remote monitoring system for longitudinal tearing of conveyor belt suitable for multi-point monitoring based on cloud technology was designed.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.
