基于LabVIEW的仿真激励器

虚拟仪器技术是指将通用计算机与功能化硬件模块结合起来,由用户根据需求自己定义和设计仪器,实现并扩展传统仪器的功能。本文介绍了一种基于LabVIEW的仿真激励器的实现方法。此仿真激励器模拟现实中的开关控制继电器给出仿真激励,输出前面板中设定的模拟数值,将采集到的离散信号显示在前面板中,通过RS422总线模拟模块间的通信状态,并能够存储和回放数据波形。

Virtual instrument technology is a connection of general--purpose computer and .functional hardware module：it is defined completely according to the needs of the user to achieve and extend the functions of the traditional instrument. This paper describes an emulator of electrical and mechanical system based on LabVIEW.The emulator simulates real button control relay to give simulation stimulus,outputs analog values set on the front panel,displays the acquired discrete data on the front panel,stimulate the communication between different modules via RS422 bus. It can also storage and playback the data waveform.
