摘要
针对机电产品远程监控中基于图像与视频的信息控制能力不足的问题,在以PLC为控制器的控制系统基础上增加了ARM核心控制器,设计并实现了一种低成本的嵌入式B/S模式的机电产品远程实时监控系统方案。该系统利用Video4linux控制USB摄像头获取机电产品工作时图像数据,并采用PNG算法实现图像压缩,通过RS232接口完成ARM与PLC间的通信,以获取机电产品实时工作参数和实现控制指令的传递。该系统通过嵌入式Boa服务器,采用B/S模式实现,并通过CGI技术实现图像和数据的远程实时动态传输。研究结果表明:"ARM+PLC+Web"交互这一组合的嵌入式系统方案,可为当前机电产品远程监控存在无法满足图像与视频中信息控制能力不足的问题提供了一个很好的解决平台。
Aiming at improving information intelligent control from the image and video of the remote monitoring system in electromeehanical products,the ARM core controller based on PLC was added as the controller＇s control system, a low cost embedded B/S mode of remote real time monitoring system scheme of electromechanical products was designed and implemented. The system utilized Video41inux to obtain electromechanical products＂ real time working image data by control USB camera, and realized image compression by PNG algorithm, completed the communication between ARM and PLC through the RS232 interface, from which can obtain the electromechanical products＂ real-time working parameters and transmit the control orders. The system was realized through the embedded Boa server and using B/S mode, CGI technology was used to realize the image and data remote real-time transmission with dynamic. The results indicate that the ＂ARM＋PLC＋Web＂ interaction of this combination of embedded system,to solve the problem that current mechanical and electrical products remote monitoring can not meet the image and video information intelligent processing needs, provides a good platform.
