汽车排放测试系统的数据采集和程序设计

Data Acquisition of the Vehicle Emission Test System and Programming

系统以LabVIEW为开发平台,NI-6221 DAQ卡为数据采集硬件,构建了基于虚拟仪器技术的数据采集系统。系统的程序部分采用LabVIEW和VC++两种程序语言相结合的方法,开发了ASM汽车排放测试的软件系统,其中包括数据采集模块、数据库开发模块、串口通讯模块、报表生成模块等。

This paper developed the data acquisition system based on LabVIEW and NI-6221DAQ.The software system of ASM vehicle exhaust pollutants testing is developed by adopting the associative method of two program languages of LabVIEW and Visual C＋＋,which includes data acquisition module,database development module,serial communication module,report generation module and etc.
