基于LabVIEW的超高频RFID读写器测试系统软件设计

摘要

对于超高频RFID读写器的射频参数测试,通常采用手工的测试方法,要求测试人员熟悉读写器的各种测试指标,并能熟练操作频谱仪,这对测试人员的要求高,且工作量大.为了改善这种情况,介绍了一种基于图形化虚拟仪器编程软件LabVIEW的超高频RFID读写器测试系统.在该系统中PC/LabVIEW控制待测对象和所需仪器组成一个测试系统,把所测数据实时的显示在前面板上,并自动保存至文件中.通过现场测试,该软件运行良好,简化了测试过程,降低了对测试人员的要求,极大地提高了工作效率.%The manual testing methods is usually used to test RF parameters of UHF RFID reader-writer, which demands the operators to be familiar with each testing index of reader-writer and the spectrum analyzer, which requires the operators to have high operating ability and lay a heavy burden on the operators. In order to improve the situation, a testing system for UHF RFID reader-writer based on Lab VIEW which is a graphical programming language for virtual instrumentation. The PC/LabVIEW controls UUT, forms the test system with other instruments and displays the measured data on the front panel timely. Then the measured real-time data is stored in the file automatically. The field test result shows the testing system works well, simplifies the testing process, reduces the requirements for operators and improve the work efficiency greatly.
