介绍了一种基于lonworks总线技术的低浓度(测量范围0～4%)瓦斯智能节点的原理以及硬件、软件的设计。该节点不仅具有显示报警功能,而且可通过lonworks总线进行通信,便于形成总线远程监控。
This paper introduces the principle of low concentration (0 ~ 4% of measuring range) methane intelligent node based on lonworks bus technology and the design of hardware and software. The node not only has display alarm function, but also through lonworks bus communication, easy to form a bus remote monitoring.
