用DLL实现自动测试存储数据的纠错处理

利用LabVIEW仪器控制技术开发了多波长计的串口控制自动测量软件,实现了由计算机控制多波长计对光栅传感阵列返回信号进行解调和结果存储。针对返回测量结果的数据错位问题,在VC 6.0中开发了动态链接库(DLL),通过在LabVIEW中调用DLL,对返回的测量数据进行检验和自动处理,确保了测量结果的完整、可靠,完善了整个测试系统。

Error Correction of the Stored Data Obtained by Automatic Measuring Using DLL

The controlling software of multi- wavelength meter based on serial port was developed using the instrument controlling technology of LabVIEW. Accordingly, the demodulation and saving for return signals of fiber grating sensor array were realized via multi- wavelength meter controlled by computer. Aiming at the problem of disorder of return data, DLL was developed using VC 6.0, and by calling DLL in LabVIEW program, checking and disposing the return data were achieved automatically. It ensures the integrity and credibility of measuring results, and perfected the whole measuring system.
