LabVIEW在变压器自动测试系统中的应用

The application of LabVIEW in automatic testing system for the transformer

为了实现电焊机变压器的自动测试,寻求一种方便快捷、成本低廉的解决方案,采用RS232串口完成LabVIEW与威格电参数测量仪GDW340B之间的通信,通过串口命令写入、数据读取、字符串处理、数值显示、数据存储,设计了一种基于LabVIEW与威格电参数测量仪GDW340B的数据采集系统。实验结果表明,该数据采集系统在测量精度、实用性上已达到了预期的设计效果,使用LabVIEW与仪器通信用于检测设备可有效提高生产效率,降低设备成本,并能很好地保证测量的准确性,是未来检测方法的发展方向。

In order to realize the welding machine using a transformer automatic testing,looking （or a convenient,low-cost solution, with RS232 serial port complete between LabVIEW and the VIGOR GDW340B electrical measurement Instrument communication.between the command through the serial port write ,data read, the character string processing, numerical display ,data storage ,designed based on LabVIEW and the VIGOR GDW340B electrical measurement Instrument data acquisition system.Experimental results show that： the data acquisition system in accuracy, practical has achieved the expected results, Communication with the device using LABVIEW for testing equipment can improve production efficiency, lower equipment costs and to guarantee good accuracy of measurement, the future direction of development of detection methods.
