摘　　要：为了提高工程机械的使用效率和可靠性,提出了一种基于嵌入式系统平台的状态监测与故障诊断系统。该系统充分发挥PC104嵌入式计算机低成本、高可靠性等优势,利用工程机械上多种可以测取的信号,将神经网络与专家系统相结合,可实现工程机械的状态报警和故障诊断。详细讨论了系统的硬件构成和软件结构以及系统的工作流程。In order to increase operation efficiency and reliability of construction machinery, a condition monitoring and failure diagnosing system based on embedded system platform is suggested. The system fully exploited the superiority of PC104 embedded computer in low cost and high reliability, using various detectable signals from construction machinery and combining nerval network with expert system to realize condition warning and failure diagnosis of construction machinery. Hardware composition, software structure and work flow of the system are expatiated in the article.
