摘　　要：针对数字量输出节点在国内市场的需求量较大,但却一直处于依赖国外进口的局面,从实用角度出发,利用LonW orks技术原理探讨了数字量输出节点的硬件与软件设计过程,主要涵盖了节点的电源、存储器扩展、I/O接口、通信接口、复位电路、服务电路、时钟电路和Neuron C应用程序。并提出了节点的抗干扰措施、性能优化方法。实验表明:该节点运行正常,能够满足常见应用系统的要求。There was a great domestic market demand for digital output nodes, but most equipment supplies depended on abroad market. In view of this, the design processes of digital output node based on LonWorks technology were introduced, including power source, memory extended interface, I/O interface, communication interface, reset circuit, server circuit, clock circuit and Neuron C programming. Anti-interference measures of node and performance optimizing methods of node were also discussed. The experimental results indicate that digital output node can provide the normal operation and meet requirements for common application systems.
