基于LabVIEW和TCP的数据采集系统的开发及应用

在冶金自动化生产线调试及生产过程中,需要对过程数据进行记录以便于故障分析。现有的组态软件可以记录过程数据,但更新周期较长,数据记录不完整;IBA公司的过程数据采集(PDA)系统采集精度高,但价格又较昂贵。因此,中冶京诚工程技术有限公司自主开发了一套数据采集系统CERI PDA,它以LabVIEW为开发平台,通过TCP连接实现PLC与数据采集系统的通信,具有数据采集、数据监视和存储、离线数据分析等功能,能够一次接收多周期信号数据,并可以最小化加载数据文件。该系统先后应用于唐山春兴冷轧薄板厂的冷轧生产线和九江钢铁公司的方坯连铸生产线,取得了良好效果。该系统操作简单,功能实用,成本较低,是进行系统调试和故障分析的有力工具。

Development and application of data acquisition system based on LabVIEW and TCP

It is necessary to record process data for fault analysis in metallurgical automated production lines.There are configuration software available on market which are capable of process data recording,however the long updating cycle time of these software packages can not cope with intensive data recording as required in some cases.The PDA(Process Data Acquisition) product of the IBM might be a solution to high accuracy data recording,but it is expensive.Therefore,a data acquisition system,CERI PDA,is develop...
