| 摘 要： | 为实现并行化、非接触、实时的细丝直径测量，设计了一种基于复杂可编程逻辑器件（complex programmable logic device，CPLD）的阵列细丝直径实时快速检测系统。阵列化传感系统，使用CPLD解算直径，并行测量多条细丝。显著降低了系统的数据传输量，缩短了直径解算时间，提高直径检测频率至5 kHz，实现了对24根细丝阵列并行测量。在0.1 mm～0.3 mm及0.3 mm～1.0 mm的直径范围内动态测量重复精度分别为3.5 μm和8.3 μm，动态重复性误差百分比绝对值分别低于1.21%与1.43%，满足了实时快速检测阵列细丝直径的需求。

| Abstract: | In order to achieve the parallel, non-contacting and real-time measurement of filament diameter, a real-time and fast detection system of arrayed filament diameter was designed based on the complex programmable logic device (CPLD). Arraying the sensing system and solving diameters by CPLD, the multiple filaments were measured in parallel. The load of the data transmission of system was significantly reduced, the solving time of diameter was shortened, the detection frequency of diameter was increased to 5 kHz and the parallel measurement of 24 arrayed filaments was realized. The repeated accuracy of the dynamic measurement of system is 3.5 μm and 8.3 μm within the diameter range of 0.1 mm~0.3 mm and 0.3 mm~1.0 mm, respectively, and the absolute value of percentage of repeatability error in dynamic measurement is less than 1.21% and 1.43%, respectively, which meets the requirements of real-time and fast detection of arrayed filament diameter. |
