【摘要】 本篇论文从基于ZigBee技术的无线抄表系统收发功能模块的研制入手，讨论在此领域ZigBee无线接入技术的特点及应用，以及具体相关模块的设计与功能实现。 ZigBee是一种低速率、低功耗、短距离无线接入技术，是专为低速率传感器和控制网络设计的无线网络协议。与其他无线协议相比，ZigBee无线协议实现了低复杂性、减缩的资源要求，并且提供了一组标准的规范。它提供了三个工作频带，以及一些网络配置和可选的安全功能，是为低速率控制网络设计的标准无线网络协议。 本篇论文侧重于收发功能模块的设计与实现。其中协调器节点及RFD(简化功能设备)节点均由一块母板和一块RF(射频)卡组成，母板驱动RF卡实现信号的收发功能。首先由协调器节点组建一个新的网络，然后RFD节点申请加入该网络，在完成节点绑定之后，此双节点网络能够实现信号的接收、发送。 为了验证设计方案的可行性和实用性，我们设计了两块相同的收发模块。烧写到协调器和RFD单片机中的主应用程序及相关文件是不同的，但是其硬件结构完全一样。 其中，射频收发芯片采用Chipion公司的CC2420，它是一个与IEEE 802．15．4兼容的RF收发器。CC2420是首款符合ZigBee技术的高集成度工业用射频收发器件，其MAC层和PHY层协议符合802．15．4规范，工作于免授权的2.4GHz频段。利用此芯片开发的短距离射频传输系统成本低、功耗小，适于电池长期供更多还原

【Abstract】 This article mainly talks about the design of receiving and transmitting module for wireless automatic meter reading system based on ZigBee coupled with the characteristic and application of this new wireless access technology --ZigBee.ZigBee is a sort of wireless access technology focusing on low bit rate、 low-power and short-distance. It is a wireless network protocol specifically designed for low rate sensor and control networks. Compared to other wireless protocols, the ZigBee wireless protocol offers low complexity, reduced resource requirements and most importantly, a standard set of specifications. It also offers three frequency bands of operation along with a number of network configurations and optional security capability.This article emphasizes particularly on the design of receiving and transmitting module. The Coordinator and RFD (Reduced Function Device) are composed of a piece of motherboard and RF card. It can receive and transmit signal through the RF card which is drove by the motherboard. The Coordinator establishes a new network firstly , the RFD applies to join the network. Such network could receive and transmit signals after the binding between the Coordinator and RFD.We designed two receiving and transmitting modules to test the feasibility and更多还原
