Design of hybrid sensor for detecting broken raw silk

For the problem of difficult detection on broken raw sillk due to the very tiny diameter of the raw sillk, a hybrid sensor for detecting the broken raw sildk was designed based on the theory of photoelectric diode. The mechanical part includes an indirect measurement mechanism of broken raw silk, a photoelectric diode installation mechanism and an installation shell. The circuit part includes several circuits about sibnal transmission, signal reception, signal processing and other modules, such as SCM module and LED drive module. The optical signals before and after the raw silk broken were collected. The results show that the sensor can convert the faint optical signals into electrical signals which can be recognized and processed directly by SCM.The sensor has high practicability and effectiveness in the detection of broken raw silk.
