摘　　要：现代测控系统应能适应复杂的监控环境,且实时性好、通信量大。该文提出一种基于DSP与LonWorks网络的分布式数据采集与状态监测系统。系统采用灵活的拓扑结构,可选用多种传输介质;基于DSP的LON节点具有很强的数据采集、处理和分析能力;网络通信采用面向对象的设计方法,通信协议中采用可预测的冲突避免算法,满足大通信量和高实时性要求,并详细描述了系统的硬件结构与软件实现。Modern network based data acquisition and condition-based monitor system should be with large communication capacity, good real-time and adaptiveness to the complicated environment. A distributed data acquisition and condition monitor system based on DSP and LonWorks is proposed. Its intelligent DSP-based nodes are powerful in data acquisition, handling and analysis. The network communication is programmed by object-oriented technique with the protocol of collision-predictable algorithm to guarantee large communication capacity and good real-time. Its hardware and software architectures are described in detail.
