基于VB和PC-6319的等温输油管路实验数据采集系统

Data Acquisition System for Isothermal Pipe Laying Experiment Based on VB and PC-6319

介绍了以VB为软件开发平台,利用PC-6319的丰富资源,构建等温输油管路实验数据采集系统的方法。详细阐述了利用DLL实现对I/O端口的读写得到测量值,给出了PC-6319各通道A/D值的标度变换通用公式,分析和解决了现场变送器的零点迁移问题,提供了对VB编写的系统软件的调试方法。

The solution to forming a data acquisition system for the isothermal pipe laying experirnent was introduced , which was based on VB and PC-6319.The technology of DLL,which can obtain the measurement by reading and writing the I/O ports,was particularized.The general formulation of transform about each channel of PC- 6319 was also presented. The problem with zero excursion in the transducer was analyzed and solved, and the debug method of the system software programmed by VB was applied.
