摘要
介绍了一种基于虚拟仪器的测量和控制恒流源的系统。阐述了系统的硬件测控原理,重点介绍系统的软件设计思想、流程设计及具体实现的方法。通过LabVIEW软件平台编写出了具有自动测量电压变化以及对电流输出进行反馈控制,界面友好,最大限度地减小温度对输出电流稳定性影响及输出调节方便的程序。
This paper introduces a system of measure and control constant current source on labview. It expoundes that the measurement and control theory of the system' s hardware, introduces design of software and realized method especially. The program written by LabVIEW can auto-measure voltage and feedback-control output-current, has friendly interface, hardly reduce the effect of temperature on current stability and adjust conveniently.
