基于Zigbee协议的无线温度传感器设计

We build multi-layer network structure—the bottom layer is a number of terminal nodes, the middle layer is data coordination node and the upper layer is general computer. The design takes ZigBee SOC production solutions CC2430 single-chip wireless node devices as a core hardware which is produced by TI Company. At the same time, it make use of source code open, easy to transplant, easy to maintain, easy expansion, a small code space(no more than 32KB), as the network protocol stack Z-Stack communication protocol. Besides, it selects DS18B20 which is high precision digital temperature sensor, to achieve a low-cost, low-power, high efficiency, on-site wireless testing device parameters.

Design of temperature wireless detection device based on ZigBee
ABSTRACT
With the development of wireless communication technologies, the trend in development of industrial detection in future is wireless detection of the temperature achieved by use of wireless sensor network. Wireless sensor network is formed by a large number of cheap micro-sensor nodes and composes a network through wireless communication, in order to coordinately perceive, collect and process the real-time information of object detection in the network coverage area, and send to observes. ZigBee technology is a wireless communication technology. The technology’s characteristics are low –cost, low-power, close-up and low-complexity and low-rate. It is the first choice of technology platform to build wireless sensor network.
本文在深入研究 Zigbee 技术，设计了适用于现场温度检测的网络结构， 构 建 了 底 层 为 若 干 终 端 节 点 ，中 间 层 为 数 据 协 调 节 点 ，上 层 为 通 用 计 算 机 的 多层网络结构。本文采用 TI 公司生产的 ZigBee SOC 解决方案 CC2430 无 线 单 片 机 作 为 节 点 装 置 的 硬 件 核 心 。采 用 源 代 码 公 开 ，易 移 植 、易 维 护 、易 扩展、代码空间较小（不超过 32KB）的 Z-Stack 协议栈作为网络通信协议。 选择高精度数字式温度传感器 DS18B20 进行节点数据的检测，组成了低成 本、低功耗、高效率的现场参数无线检测装置。

The paper completes the design of the hardware and programs the codes on the CC2430 and micro-chip. ZigBee wireless sensor networks can replace the traditional temperature detection devices, since the traditional temperature detection device is complicated equipment, requires a lager number of wires, and is not easy to change the location of monitoring points. This paper provides new solution to design of temperature wireless detection devices and application of actual network. Keywords: ZigBee,CC2430,DS18B20
