基于LonWorks控制网络的多功能节点设计

Designing of Multifunctional Nodes Based on LonWorks Controlling Network

针对目前LonWorks控制网络系统中节点设计仍未形成统一、规范的体系问题,为提高LonWorks网络节点的控制能力,在LonWorks控制网络中采用了多处理器结构来设计功能节点。设计中,以VHDL语言来实现FPGA/CPLD与MCS-51单片机的节点内总线接口的逻辑设计,使得节点中不同功能模块之间的连接以及节点硬件结构的改变更加灵活、简单。

Nowadays,there is no unified and normative system in node designing.A type of the multifunctional nodes of controlling network using multiply processors was designed for improving the controlling ability of LonWorks network.VHDL language was applied to realize the designing of Bus Interface logic based on MCS-51 microprocessor and FPGA/CPLD.In this way,the combination of the multifunctional modules and the change of the hardware structure in nodes will be more flexible and simple.
