摘　　要：针对目前城市空气质量监测中人工取样和便携式分析仪现场监测法存在的采样点有限、覆盖范围小、实时性差等不足,提出一种城市空气质量远程分布式监测系统设计方案。主要思想为:在污染物观测区域分布式部署JN5148无线数据采集节点并定时采集空气质量各参量,各区域的数据采集量化并经Jen Net无线网络传输和汇总后通过相应的嵌入式web服务器接入互联网,远程用户可通过浏览器查看空气质量数据。实现了大范围分布式数据采集和远程实时监测,也为污染评价、决策和预警的研究提供数据支持。实验测试表明,前端无线数据采集网络的通信吞吐量和嵌入式web服务器的访问均已达到系统需求,验证了系统设计方案的可行性。Because of the existence of limited sampling points, small coverage and poor real-time performance in city air quality monitoring, we propose a design scheme of urban air quality remote distributed monitoring. The main idea include collecting air quality data periodically through distributed deployment of JN5148 wireless data acquisition node in pollution monitoring area, sending the data which has been collected and quantified to the Internet through the corresponding embedded web server after the transmission and collection by Jen Net wireless network, the remote user view the air quality data through the browser. Implements a wide range of distributed data acquisition and remote real-time monitoring.. It can also provide data support for pollution evaluation, decision-making and early warning. Test results show that the throughput of front-end wireless data acquisition network and the access performance of embedded web server has reached the system requirements. It proved the feasibility of monitoring program.
