【摘要】 针对空气质量监测中地理位置复杂、不易布线及现场状况突发等特点,采用ZigBee技术进行现场数据采集网络布置。考虑到ZigBee节点的处理能力有限,为避免信息孤岛,设计了嵌入式无线网关。该网关实现了数据现场采集远程监测。网关引入ARM11架构硬件平台和Linux操作系统,构建了空气质量监测系统。实测结果验证了该系统在空气质量检测中的可行性及实用性。更多还原

【Abstract】 Aiming at the features of air quality monitoring,e. g.,complexity of geographical locations,difficulties for wirings,and unexpected site conditions,etc.,thus the ZigBee technology is used to build data acquisition network. Considering the limited processing capability of ZigBee nodes,to avoid information islanding,the embedded wireless gateway is designed and realized for field data collection and remote monitoring. The hardware platform of ARM11 architecture and Linux operating system are introduced into the gateway,the air quality monitoring system is built. The results of practical tests verify the feasibility and practicality of the system in air quality monitoring.更多还原
