目的 设计基于 ARM9 的多功能贴标控制系统，解决目前国内市场上贴标机只能完成对扁瓶、圆瓶等单一类型瓶的贴标功能，且贴标精度低、正标率不高的问题。 方法 把变频电机频率作为参数基，依据运动关系进行数学分析计算，得出电机停止脉冲偏移量、启动延时时间参考值，结合伺服电机的闭环控制来精准定位标签在包装瓶上起始贴标位置，确保贴标时两者不会产生相对滑动，从而达到高的贴标质量。 结果 对贴标机 3 种方式分别进行现场测试，经由数据分析，该贴标机在扁瓶双侧贴标、圆瓶连续贴标、异形圆瓶定位贴标情况下，贴标精度为±1 mm，贴标速度分别可到达每分钟 60， 30， 20 瓶，正标率分别为 97.9%， 99.1%， 98.7%。 结论 该贴标控制系统采用 ARM9嵌入式系统取代传统 PLC 控制，贴标范围广、响应快速稳定、实时性强、交互界面友好，同时降低了设备成本，保证了较高的贴标精度，广泛适用于多种类型瓶的贴标控制。

Aiming at the status quo that labeling machine can only complete the sector or round bottle type labeling function and the labeling rate is low in the domestic market, the ARM9-based multi-function labeling control system was designed. Based on the motion relationship, taking the frequency of conversion motor as a parameter, the motor stopping pulse offset and startup latency time reference were calculated. Combined with closed-loop control of servo motor, the start labeling position of the labels on the bottles was decided, making sure that the label had no relative sliding at time of labeling, so as to achieve the high quality of labeling. Through the analysis of data of labeling machines’ field test, in cases of labeling double sides of flat bottles, labeling round bottles continuously and positioning labeling shaped round bottles, at the labeling precision of ±1 mm, labeling speeds could reach 60 bottles/min, 30 bottles/min and 20 bottles/min, and standard rates of labeling machine could keep above 97.9%, 99.1%, 98.7%. Using ARM9 embedded system to replace traditional PLC system, this system was used widely, with rapid response, high real-time manner and friendly interface, which did not only reduce the equipment cost, but also ensured the higher precision of labeling. The system can be widely used in various types of bottle label control.
