摘要
阐述了开放式虚拟仪器平台LabVIEW的特点,并介绍了在该平台上使用普通数据采集卡进行数据采集的动态连接库的设计方法。在此基础上开发了一个由计算机控制的数据采集系统,并对电动汽车电机电枢电流、车轮速度以及车身速度等信号进行了实际采集。实验证明采用这种方法省去了复杂的语言编程,缩短了软件的开发时间,简化了开发过程,同时也增加了应用的灵活性。
The characteristics of opening Virtual instrument LabVIEW are described.A DLL design method of data acquisition based on LabVIEW using a general acquisition board is introduced.Based on that,a data acquisition system controlled by computer is developed.The data of electromotor armature electric current ,wheel speed and bodywork speed of the electric vehicle is collected using this system,which proves that this method can avoid the complicated computer program,shorten software-developing time ,simplify the development process,and increase the application agility.
