基于VB与研华数据采集卡的数据采集系统设计

根据DC600V青藏发电车电源检测的需要,利用研华数据采集卡搭建数据采集系统的硬件平台,介绍系统的硬件结构和软件结构,在此基础上以VB 6.0为平台,采用中断触发方式进行数据采集,实现数据的实时采集、动态显示等,并利用VB和SQL数据库技术,建立设备数据库,为用户提供机车运行状态的诊断和预测。实验证明该系统稳定性好、准确性高。

Design of Data Acquisition System Based on VB and Advantech Data Acquisition Card

According to the requirements of DC600V Qinghai-Tibet generation car power test system, this paper constructs the hard- ware platform of date acquisition system using Advantech data acquisition card, and introduces the hardware structure and software structure of the system. On the basis of this, the system uses interrupt triggering to acquire data, realizes real time data acquisition and displaying data with dynamic curves etc. , and utilizes VB 6.0 technology interview of SQL Server 2000 databases for creating e- quipnaent states information, under VB 6.0 environment. The experiments show that the system is of good stability, high accuracy.
