基于射频技术的无线网络中继器的设计

Design of wireless network relay based on radio-frequency

无线网络可以克服传统网络技术中有线传输介质带来的组网困难等缺点。根据现场控制需要,基于射频技术,设计了一种使用公用频段和具有主从星型拓扑结构的无线控制网络中继器。它采用两种不同功率和频段的射频模块,与现场控制节点一起构成完整的无线控制网络。具体介绍了它的硬件构成和软件流程。

Wireless network could overcome weakness of conventional network.A wireless control network based on radio-frequency technology is designed to satisfy actual control needs.This paper introduce a wireless control network relay which consists of master and slave equipments,using public frequency channel and star topology.It uses two kind radio frequency module which have different power and frequency band and forms whole wireless control network with field control nodes.This paper discusses it ＇s hardware frame and software flow chart in detail.
