摘　　要：为了满足频率测试系统的便携性要求,利用NI公司的CompactRIO(CRIO)平台设计了便携式频率测试系统。利用LabVIEW FPGA开发了CRIO的底层FPGA模块,实现对频率数据采集模块的控制与管理;利用LabVIEW RTOS开发了CRIO的基于Lunix的核心软件模块,实现了对频率数据的变换、管理及与上位机通信;最后利用LabVIEW开发了上位机显示和管理软件。基于CRIO的便携式频率测试系统具有体积小、重量轻、精度高等优点,充分满足了航空发动机频率测试系统的功能要求。In order to meet the requirements of portability,a portable frequency testing system is designed by NI CompactRIO（CRIO） platform.The FPGA module underlying the CRIO is developed with Lab VIEW FPGA while the control and management of frequency signals collection module are implemented.The core module of CRIO based on Lunix is developed by using Lab VIEW RTOS while the organization,management of acquisition data and communicating with host computer are implemented.Finally,Lab VIEW is used to develop the data management software which implements the real-time display and storage of acquisition data.With the advantages of small size,light weight,high precision,better efficiency and flexibility,the portable frequency testing system based on CRIO fully meets the requirements of portable testing for the aero-engine.
