摘要
主要介绍了PCI-1716多功能数据采集卡在轿车电动助力转向器性能测试系统中的应用;借助于研华PCI-1716多功能数据采集卡和32位动态链接(DLL)驱动程序接口,采用VB编程平台,实现对PCI-1716数据采集卡的驱动和控制;根据轿车电动助力转向器性能测试系统的要求,所有数据的采集使用PCI-1716多功能数据采集卡完成,最终实现对实时数据的采集、分析和处理,完成轿车电动助力转向器总成在装配线末端多种性能测试项目的在线测试;PCI-1716多功能数据采集卡采用软件定时器控制数据采集流程,利用软件触发方式触发A/D转换,各采集通道的输入电压范围设定为-10V～+10V。
An application of the PCI-1716 data acquisition card in the performance testing of the electric power steering system is inves ligaled and developed. In the test system, all online data are collected with PCI _ 1716 and a 32 bit DLL driver on the platform of Microsoft Visual Basic. This makes the online data logging, processing and storing available. Performance tests of the electric power steering system including the function testing, input/output feature, the current feature of the steering assist motor and unloaded rotation torque can be con- dueled. PCI--1716 data acquisition card used software timer to control data acquisition process and trigger A/D conversion, input vohage range of all the acquisition channel is set to --10V--q-10V.
