基于OPC技术的轮毂装配线监控系统

针对当下生产线中由高级编程语言开发的上位机功能不明确、与OPC技术结合难的情况,本文结合一般生产线的运行流程,设计了一个基于OPC技术的上位机监控系统,并在一条实际的装配线上进行了部署.系统的通信部分以Qt和KEPServerEX结合的方式构建了高效的OPC通信机制,功能部分则是将从服务端接收来的数据分别汇入存储、实时显示计算、报警处理、图表分析四个模块,并在各个模块中进行相应的处理.此外,系统还包括工位校验、打标等控制模块,用来实现客户端对PLC的控制操作.实验结果证明,该系统稳定性较高,功能齐全,可满足多数生产线中上位机软件的需求.

Monitoring System of Wheel Hub Assembly Line Based on OPC Technology

The function of the host computer developed by the high-level programming language in the current production line is undefined and it is difficult to integrate with OPC technology. Therefore, this study combines the operation process of the general production line to design a host computer monitoring system based on OPC technology, which is applied to an actual assembly line. Qt and KEPServerEX are combined to construct an efficient OPC communication mechanism in the system, and the data received from the server is input into modules of storage, real-time display calculation, alarm processing, and chart analysis for further processing. In addition, the system also includes control modules such as station check and marking, enabling the client’s control over the PLC. Experimental results prove that the system has high stability and complete functions, which can meet the requirements of the host computer software in most production lines.
