基于LabWindows和xPC的半实物仿真平台人机界面构建

Construction of Human Machine Interface for Hard-ware-in-the-loop Test Platform Base on LabWindows and xPC

针对在xPC平台下开发的实时仿真系统依赖于matlab环境,影响其在工程中应用,提出了一种较快捷的实时控制软件开发方法:在LabWindows/CVI开发环境下利用xPC中的API函数开发出软件人机界面,实现双机模式下实时控制软件的一体化开发。所构建的人机界面不仅增加了操作的方便性和可移植性,而且使得测试平台显得更加真实直观。通过应用实例有效验证了上述方法。

The real-time simulation system developed on xPC platform depends on MATLAB commonly, and it affects its application in engineering. A more efficient development methods of real-time control software was proposed, the human-machine interface was developed with API functions ofxPC by LabWindows/CVI which achieved integrated development of real-time control software under the dual mode.The constructed human machine interface not only improves the convenience in operation and easy to transplant,but also makes the test platform more realistic and visual, the described method is confirmed by the experimental results.
