电容式电子清纱器系统的设计

针对目前电子清纱器主要以模拟电路为主,受元器件老化的影响较大,同时检测效率过低等问题,提出了将数字化电路应用到电子清纱器中的设计方法,以电容为传感元件,实现了一种电容式电子清纱器系统的设计。电容式电子清纱器系统以ARM STM32芯片为CPU,通过系统检测模块对纱线的质量进行了检测,将检测的数据传送给中段板,中段板将储存的数据向上传递给上位机,检测模块同时具有报警显示功能。检测模块通过RS-485总线与中段板进行实时通讯,以实现各指令的交换,并接收从上位机发送的配置信息。上位机可通过界面将实时数据进行直观的展现。通过对纱线的检测实验表明,该系统具有高精度、低功耗、实时性的特点,可广泛应用于纱线纺织工业,对纱线质量检测有着较高的水准。

Design of capacitive electronic yarn clearer system

Aiming at the problems of the present electronic yarn clearers are mainly designed by analog circuits, which are great influenced by aging of components, and the low detection efficiency, a kind of digital circuit was designed into the electronic yarn clearers and the ca- pacitance was uesd as the sensing element. The development of a capacitive electronic yarn clearer system was achieved. The ARM STM32 chip was used as the CPU of the system, the quality of yarn was detected through the detecting module, the detected data would be delivered to the middle-board, and the stored data would be delivered to the PC by middle-borad. The RS-485 bus was used for the detecting module to communicate with the middle-board, which could achieve the goal of commands exchanging, and the detecting module could receive configu- ration from PC by RS-485 bus. The yarn detecting experiment shows that the system has the characters of accuracy,low power and real-time, which can be widely used in the textile industry of yarn and has a high level for yarn＇s quality detecting.
