本文介绍了工程机械工况参数监测系统的设计思想及软、硬件设计技术。该系统将数据采集分析系统分成了在线的数据采集机、离线的分析处理机和传递数据的中继机三部分．采集机直接安装在各种工程机械上，实时记录工程机械的各种工况参数，在机械出现故障或参数越限时进行报警，采集机采集和存贮的信息由中继机传递到分析处理机中进行离线分析和处理。 This article introduced the engineering machinery condition parameter monitoring system design and software and hardware design techniques. The system divides the system of data acquisition and analysis into three parts: the online data acquisition machine, the offline analysis processor and the data relay machine. Collector installed directly on a variety of construction machinery, real-time recording of construction machinery parameters of various operating conditions, mechanical failure or more parameters when the alarm, collectors and storage of information collected by the relay to the analysis processor In the offline analysis and processing.
