Design and implementation of online tension sensor

在化纤生产过程中,化纤张力是影响产品质量的一个重要控制参数,为了实时在线检测化纤的张力信息,本文设计了一款应用于高速纺丝生产环节中的在线张力传感器。传感器以高性能的LPC1768为主控中心,数据采集单元对信号进行预处理,采集数据经过A/D转换后传输到控制中心,并通过通信模块传输到上位机显示出来。传感器采用S型曲线算法,达到精准控制步进电机的目的,可以更好地提高测试精度。实验表明:该传感器具有实时性好、稳定性强等特点。

In the process of chemical fiber production, chemical fiber tension is an important control parameter affecting product quality. In order to detect the tension information of chemical fiber in real time, an online tension sensor applied to high-speed spinning production is designed. The sensor takes the high-performance LPC1768 as the main control center. The data acquisition unit preprocesses the signal, transmits the collected data to the control center after A/D conversion, and transmits it to the upper computer for display through the communication module. The sensor adopts S-curve algorithm to accurately control the stepping motor, which can better improve the test accuracy. Experiments show that the sensor has the characteristics of good real-time and strong stability. At the same time, the intelligence and automation of yarn tension detection are further improved, which is of great significance to the liberation of labor force, and can bring better economic benefits to enterprises and even the textile industry to a certain extent.
