摘　　要：针对液压系统故障对工程机械设备工作效率的限制,提出一种基于LabVIEW的远程液压缸状态检测系统。该系统架构分为3层:现场设备层是以NI数据采集卡为核心实现数据的采集和初步处理硬件平台;数据控制层主要借助串口通信和上位机编程实现数据的采集处理、数据存储、限位报警等功能;监测访问层主要以TCP通信协议为基础实现数据的远程传输及远程故障诊断。试验结果显示:基于LabVIEW远程监测系统数据传输效果稳定、可靠性高。Aiming at the limitation of hydraulic system fault on the efficiency of construction machinery and equipment,a remote hydraulic cylinder status detection system based on LabVIEW was proposed.The system architecture was divided into three layers.The field device layer is based on the NI data acquisition card as the core to realize data acquisition and preliminary processing hardware platform.The data control layer mainly uses serial communication and host computer programming to realize data acquisition,processing,data storage and position alarm and other functions.The monitoring access layer is mainly based on the TCP communication protocol to realize remote data transmission and remote fault diagnosis.The test results show that the data transmission effect of the LabVIEW remote monitoring system is stable and reliable.
