摘　　要：L-N总线是研发自主智能建筑电气监控技术的成功尝试。针对L-N系统的有线布网特性,为解决监控系统后期应用终端的可扩展性,为L-N监控节点设计ZigBee无线通信子网,在监控系统底层构建无线通信子系统及其通信协议,扩展节点监控无线I/O通道。同时通过对L-N节点的可选语音功能扩展设计,支持系统局域监控的无界面交互。对扩展设计进行了多种条件下的无线和语音功能测试,结果表明所设计的扩展L-N节点,其无线和语音监控功能具有较高的实时性和可靠性,有效提升了基于L-N总线的智能建筑电气监控系统的应用灵活性。L-N bus is a successful attempt to develop independent intellect electrical monitoring technology for intelligent buildings. According to the wired network characteristics of L-N system, ZigBee based wireless communication sub network is designed for L-N monitoring node in order to solve the scalability of the application terminals in the later stage of the monitoring system. The wireless communication subsystem and its protocol are constructed at the bottom of the monitoring system to expand wireless I/O channels for the L-N nodes. At the same time, optional speech function of L-N node is designed supporting interface free interaction of local monitoring. The results show that the designed L-N node with wireless and speech extension is of high real-time and reliability, which effectively improves the application flexibility of intelligent building electrical monitoring system based on L-N bus.
