摘要
针对传统的单传感器总线制火灾检测系统存在的不足,设计了一种基于ZigBee的多传感器无线网络系统,并将其应用于智能家居火灾预警中。采用AM2302温湿度传感器和MQ2气体传感器作为传感单元,CC2530作为数据处理和无线收发单元。节点采集的数据经ZigBee网络传输后,汇聚至上位机数据融合系统进行全局判决,根据判决结果进行声光报警和短信报警。实验表明,系统采集数据准确可靠,可以有效提高火灾预警系统的鲁棒性。
Aiming at the drawbacks of traditional single-sensor fire detection system using bus, the authors designed a multi-sensor wireless network system based on ZigBee, and applied it in fire early-warning of smart home. AM2302 temperature and humidity sensor and MQ2 gas sensor were chosen as sensing unit, and CC2530 was used as data processing and wireless transceiver unit. After ZigBee network transmitting, data was aggregated to data fusion system for global judgment on PC, then sound and ligllt alarm or SMS alarm was conducted based on the verdict. Experiments show that the system can collect data accurately and reliably, and effectively improve the system' s robustness.
