Study on Data Acquisition System of Production Line for MES

摘要:

为满足生产管理与在线监测的需要,设计并实现了一个面向MES的生产线数据采集系统；该系统采用了一种基于PROFIBUS-DP和OPC技术的数据采集方法,实现了现场采集数据的高速及稳定的传输,保证了不同设备之间良好的兼容性；用户可以通过OPC客户端完成对生产线状态的远程监控,当采集到的参数超过设定的阀值时,系统可以自动报警并做出相对应的处理；经过试验表明,该系统各项性能良好,已经实现MES底层硬件和软件的深度融合,在生产线监控方面有着很重要的应用价值。

Abstract:

In order to meet the requirement of production management and online monitoring, design and realize a data acquisition system of production line for MES. The system which uses a method of data acquisition based on PROFIBUS-DP and OPC technology, realizes high speed and stable transmission of the on-site acquisition data and ensures the good compatibility between different devices. Users can realize remote monitoring of production line status through the OPC client. When the collecting parameters exceed a set threshold, the system can automatically alarm, and make corresponding processing. By experiment, the system has good performance, has achieved the deeply integration between the hardware and the software of MES and has a very important application value in monitoring of the production line by experimentation.
