摘　　要：介绍了一种基于CAN总线和虚拟仪器技术的工程装备分布式状态监测系统。该系统由上位机和智能检测节点构成。上位机主要负责人机交互、数据记录、状态监测、系统管理、等任务,智能检测节点接收上位机的指令,进行状态参数的检测、控制与数据上传工作。利用图形化的虚拟仪器开发平台LabVIEW完成了上位机的软件应用程序的开发。智能检测节点底层程序用C语言编写,主要包括指令接收、AD转换和控制量输出等模块。This paper introduces a kind of distributed test system based on CAN （Contoller Area Network） bus and virtual instrument technique for engineering equipment. It consists of host and intelligent node, with parameter signals communication through CAN bus to form a distributed high-precision status parameters test system. The host computer implements the user interaction, data storage, status monitoring, power measurement and computation as well as management. The client unit reads the commands of host, detects all the parameters of system and transmits the data. The hardware and software structure of the distributed testing system （client） with ATmega128 micro single chip computer and communication module are implemented. And the apphcation software was developed with graphical virtual instrument language LabVIEW.
