摘要
设计了一种基于物联网架构的智能火灾预警系统,以ZigBee无线传感器网络为底层的数据采集和传输网络,完成对火灾信息的准确感知。WSN节点以CC2530和CC2591为处理和无线收发单元,以DHT21和MQ传感器为数据采集单元,实现了多传感器数据采集。采用Qt技术设计了系统GUI,基于qextserialport类和SQLite数据库实现了系统的串口通信和数据库操作。测试表明,系统准确可靠,GUI界面友好,易于操作。
This paper designs an intelligent fire warning system based on the Internet of Things architecture. It uses ZigBee-WSN as un derlying data collection network to complete accurate perception for fire information. The WSN nodes use CC2530 and CC2591 as pro cessing and wireless transceiver units, use DHT21and MQ sensors as data collection units, and thus realize muhksensor data collection. System GUI is designed with Qt technology. Serial communication and database operation based on qextserialport class and SQLite data base are realized. Tests show that the system is accurate and reliable, and its GUI interface is friendly and easy to operate.
