基于LabVIEW的CANDU6模拟机I/O板卡测试系统

A Test System of CANDU6 Simulator I/O Card Based on LabVIEW

为了对不同的CANDU6模拟机I/O板卡进行测试,避免重复接线,本文设计了基于LabVIEW的模拟机I/O板卡测试系统。首先,将待测板卡插到模拟机测试工装上,然后运行根据调试程序文件编写的LabVIEW软件,该系统就可以实现自动测试。在测试过程中,PXI采集板卡根据软件的命令,采集输入的模拟或者数字信号,输出I/O板卡需要的模拟信号或者数字信号。该系统不但提高了调试的效率,而且提高了调试的可靠性。

In onler to test different simulator I/O card, and to avoid repeating wiring, this article designed a test system based on LabVIFW. Firstly, insert the board under test into simulator test fixtures, secondly, run LabVIEW software according to debug program files, lastly, the system can implement the test automatieally. In the process of the test. PXI acquisition boards collect inputing analog or digital signal, and output analog signal or digital signal which the I/O card needs by order of the software. The system not only improves the efficiency of the debugging, hut also improves the reliability of the debugging.
