摘　　要：提出了一种采用LonWorks技术和单片机技术设计的协议转换网关 ,实现了将基于Modbus总线的设备集成到LonWorks现场总线控制网络。该网关能够通过自主的协议转换 ,使两个网络信息互通 ,并实现相应的控制。具体介绍了实现技术、硬件设计、软件设计。A protocol conversion gateway designed by LonWorks technology and single chip computer technology is stated. Thus the Modbus based devices can be integrated into LonWorks fieldbus control network.The gateway is able to implement information of two network to be mutually communicated and relevant control because of its own protocol conversion.The technology of implementation,hardware and software design,as well as design method for interface between single chip computer and LonWorks control module are presented concretely.
