摘要 针对生丝直径很细导致无法准确检测出生丝断丝的问题,依据光电管对射原理,设计出一种检测生丝断丝的传感器。传感器由机械部分和电路部分组成:机械部分包括生丝断丝间接测量机构、光电管安装机构和安装外壳;电路部分包括信号发送、信号接收、信号处理等电路,单片机电路,LED驱动电路。将传感器安装在纤度机上进行实验,并对生丝断丝前后的输出信号进行采集。结果表明:传感器成功将生丝断丝产生的微弱光信号转换成单片机可识别和处理的电信号,实现了生丝断丝故障的准确检测和报警提醒功能;该传感器在生丝断丝故障检测中具有较高的实用性和有效性。 For the problem of difficult detection on broken raw silk due to the very tiny diameter of the raw silk,a hybrid sensor for detecting the broken raw silk was designed based on the theory of photoelectric diode.The sensor is composed of a mechanical part and a circuit part.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 signal transmission,signal reception,signal processing and other modules,such as SCM module and LED drive module.The measurement was conducted after the sensor was installed on a denier machine.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.
