传统的有线温度测量由于线路复杂常存在造价昂贵、信噪比低等问题,为解决这些弊端,设计了一种基于CC2530和ZigBee协议的无线温度传感器网络,硬件结构非常简单,更有利于狭小空间下的温度监测;该系统使用DS18B20数字温度传感器对环境进行温度测量;以射频芯片CC2530为核心,使用其标准的增强型8051CPU对数据进行处理与控制;使用ZigBee协议建立无线通信网络,将测得的环境温度通过LCD显示;最后,通过实验测试证明该系统可以有效地测量不同地点的温度并无线组网,能够实现低功耗、高精度、远距离的无线传输.
Traditional wired temperature measurements often present expensive, low signal to noise ratio and other issues due to the complicated lines. To solve these drawbacks, designed a wireless temperature sensor network based on CC2530 and ZigBee Z--Stack, and its hard-ware structure is so simple that it is more conducive to temperature monitoring in the narrow space. In this system, using DS18B20 digital temperature sensor measurement the environment temperature; using CC2530 RF chip as the core and its standard enhanced 8051 CPU for data processing and controlling; using the ZigBee Z--Stack to establish the wireless communication sensor network, and displaying the measured temperature data by LCD. Finally, proved by a series of experimental test that the system has the function of both measuring temperature of different areas and forming wireless networks, realized the wireless transmission of low power, high accuracy, long distances.
