基于ZigBee协议的煤矿瓦斯和温湿度监测节点设计

摘要

介绍了一种基于ZigBee协议、以CC2430为核心的煤矿瓦斯和温湿度监测节点的软、硬件设计方案.该节点采用瓦斯传感器LXK-3和温湿度传感器SHT11来采集煤矿瓦斯浓度和温湿度信息,经CC2430内嵌的8051微控制器进行相关数据处理后,利用CC2430的数据收发功能实现了节点之间基于ZigBee协议的无线通信.测试结果表明,该节点数据传输准确性高.%The paper introduced a design scheme of monitoring node of coal mine gas, temperature and humidity based on ZigBee protocol and CC2430 chip. The node firstly uses model LXK-3 gas sensor and model SHTll temperature and humidity sensor to collect information of gas concentration, temperature and humidity, then processes relational data through 8051 microcontroller embedded in CC2430, and finally realizes ZigBee wireless communication between the nodes by use of functions of data receiving and sending of CC2430. The testing result showed that the node can transmit data correctly.
