摘要：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。

0引言

随着信息技术的发展，工业计算机控制系统的应用在逐步扩大[1]。一般情况下，由单片机构成的系统，都需要向上位机进行数据传输，实现通信功能，从而使得上位机与单片机功能互补。过去常用的RS-232通信标准，虽然稳定性和速率都有所提高，但因其通信距离过短，单片机数量多，无法满足实际需求[2]。本文采用的RS-485通信协议传输速率高、距离远，可实现一对多通信的目的，构造简单、方便维护、成本低等优势在工业计算机控制系统中占有重要地位[3]。

纺织行业一直被认为是劳动密集型行业，自动化水平低。在纺纱过程中，当纺纱张力大于纺纱段强力时就会出现断头，不仅造成原料浪费，而且增加工作量,也降低了成纱质量[4]。……
