摘要当今时代，是一个信息化时代，信息的沟通能力是信息技术发达与否的首要体现。人工智能仪表读取、无线楼宇监控、工业控制及监测……等等，这些现代化技术均需要信息沟通智能化的技术支持。当中，传感技术是信息沟通的最基本的技术。本设计完成了利用单片机CC2530实现Zigbee接口与RS485接口的通讯转换，为RS485接口与Zigbee无线通讯的协议转换提供硬件电路支持，并且其通讯过程采用光耦隔离式通信，以便因某一部分电路发生故障的时候能够保护通讯模块，从而节省成本损耗。同时考虑各个接口及单片机工作所需要的电源电路，完成RS485接口与Zigbee接口协议的转换模块硬件设计。基于Zigbee技术的无线传感器网络应用在Zigbee联盟和IEEE802.15.4组织的推动下，结合其他无线技术可以实现无处不在的网络，这正是本次设计采用Zigbee无线网络的原因。关键词:Zigbee无线网络；CC2530；光耦隔离；RS485AbstractTodayisaneraofinformationcommunication.CommunicationskillsofITisthefirstembodimentwhetherinformationtechnologydevelopedornot.AImeterreading,wirelessbuildingcontrol,industrialcontrolandmonitoring......etc.Thesemoderninformationcommunicationtechnologiesrequireintelligenttechnicalsupport.Amongthem,thesensortechnologyisthemostbasicofinformationcommunicationtechnology.Thepurposeofthisdesignisthattheuseofsingle-chipCC2530ZigBeeinterfacewiththeRS485interfacecommunicationswitch,supportedbythehardwarecircuitforRS485interfacewithZigbeewirelesscommunicationprotocolconversion,optocouplerisolatedcommunicationandthecommunicationprocess,inorderduetothefailureofapartofthecircuitwhenabletoprotectthecommunicationmodule,thussavingthecostoflosses.Powercircuit,takingintoaccountthevariousinterfacesandmicrocontrollerneededfortheworktocompletetheRS485interfaceandthetheZigBeeinterfaceprotocolconversionmodulehardwaredesign.BasedontheZigbeeAllianceandIEEE802.15.4organizationstopromote,thetheZigbeetechnologyofwirelesssensornetworkapplications,combinedwithotherwirelesstechnologiescanachieveubiquitousnetwork,whichisthedesignofZigbeewirelessnetworkreasons.Keywords:Zigbeewirelessnetwork;CC2530;optocouplerisolated;RS485目录摘要...................................................................................................................IAbstract........................................................................................II第1章绪论.......................................................................................................11.1Zigbee无线网络技术的研究背景..............................................................11.2目前ZigBee的发展状况和前景................................................................11.3本设计的工作内容...................................................................................21.4本章小结...............................................................................................2第2章zigbee无线网络原理...............................................................................32.1Zigbee主要通信硬件介绍.......................................................................32.1.1光耦器件6N136芯片......................................................................32.1.2单片机CC2530芯片.......................................................................32.1.3通信MAX485芯片..........................................................................52.2光耦通信硬件设计框架............................................................................62.3本章小结............................................................
