Aiming at the automatic detection and management for spun yarn breakage, the remote monitoring system has been developed. Relevant data of yarn breakage are collected by Ring Route yarn breakage detection device,and the data transmission among ARM and multiple single chip computers is conducted via RS-485 communication. The communication software is developed, the yarn breakage data of all the spinning frames are monitored by IPC via WiFi, and the data are stored in yarn breakage data list for inquiry statistics. The RS-485 communication process and the developing concept of communication software,as well as related critical technology are described emphatically. The practice indicates that the system satisfies basic demands for quality management of yarn breakage.%针对细纱断纱自动检测与管理问题,开发细纱断纱远程监控系统。由Ring Route断纱检测装置获取断纱相关数据,并通过RS-485通信完成ARM机与多个单片机之间的数据传输。开发通信软件,利用无线WiFi,由一台工控机监控所有细纱机上的断纱相关数据,并将数据存储在断纱数据表中供查询统计。重点阐述了RS-485通信过程和通信软件开发思路与其中的关键技术。实践表明系统满足断纱质量管理的基本需求。
