【摘要】：针对镁熔液第一气泡检测在工程应用中的诸多难点,采用DM642芯片构建的嵌入式图像处理系统平台,以西门子S7-200为控制单元,设计了DSP与PLC通信的接口电路,并利用均值滤波算法实现了镁熔液第一气泡的检测。实验结果表明:算法能成功的检测出第一气泡,并且算法检测到镁熔液第一气泡后,PLC能快速响应并根据程序输出,成功实现了DSP与PLC的通信,为图像处理应用于工业现场镁熔液含氢量实时检测提供了新的方案。
[Abstract]:In view of the difficulties of the first bubble detection of magnesium melt in engineering application, the embedded image processing system platform based on DM642 chip and Siemens S7-200 as control unit are used to design the interface circuit between DSP and PLC. The detection of the first bubble in magnesium melt is realized by means of the mean filter algorithm. The experimental results show that the algorithm can detect the first bubble successfully, and after detecting the first bubble of magnesium melt, PLC can respond quickly and output according to the program, and successfully realize the communication between DSP and PLC. It provides a new scheme for the real-time detection of hydrogen content of magnesium melt in industrial field by image processing.
