基于CVI的多通道串口板卡测试软件的设计与实现

针对一种刚开发的、可快速集成实验系统的智能多串口卡，设计实现了专门对其量身定做的测试其数据通信性能的软件。设计此卡的目的在于解决无人机半物理仿真实验存在的传感器众多并且接口不统一的问题。该测试软件是基于功能强大的虚拟仪器软件开发工具LabWindows/CVI完成的。该软件解决了一般调试助手不能对板卡内存进行访问，并且不能同时同步进行多通道收发的问题，客观准确地验证了板卡性能，同时提出了简化程序的一种新方案。

Design and Realization of a Testing Software For the Multi-Serial Ports Card Based on CVI

A testing software for a kind of multi-serial ports intelligent card to test its communication performance is designed.The testing system is developed by the software LabWindows/CVI which always being used as the virtual instrument development tool for its powerful function.Most of the existent serial ports testing software can not communicate by more than one port at the same time,or read or write even a byte to the card memory.But this design can easily solve the problem.It tests the communication performance of the multi-serial ports card accurately and objectively.Simultaneously,a new method is provided to simplify programs.
