基于ZigBee的RS485硬件设计论文.doc

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。
2530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IEEE ,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。

Abstract
Today is an era of munication. Communication skills of IT is the first embodiment whether information technology developed or not. AI meter reading, wireless building control, industrial control and monitoring ...... etc. These modern munication technologies require intelligent technical support. Among them, the sensor technology is the most basic of munication technology.
The purpose of this design is that the use of single-2530 ZigBee interface with the RS485 munication switch, supported by the hardware circuit for RS485 interface with Zigbee munication protocol conversion, optocoupler munication and munication process, in order due to the failure of a part of the circuit when able to protect munication module, thus saving the cost of losses. Power circuit, taking into account the various interfaces and microcontroller needed for the work plete the RS485 interface and the the ZigBee interface protocol conversion module hardware design. Based on the Zigbee Alliance and IEEE to promote, the the Zigbee technology of wireless work applications, combined with other wireless technologies can achieve work, which is the design of Zigbee work reasons.
