基于物联网技术的跨区域气象环境污染监测系统

Based on the Equipment Related to the Communication Technology of the Meteorological Environment Pollution Monitoring System

由于不同区域的污染信息关联性较差,当前的气象环境污染指数测量设备无法对不同区域的污染信息进行准确检测分析,提出一种基于物联网技术的气象环境污染监测系统,并给出了软硬件设计方法。系统采用分层化、模块化、网络化的物联网结构,由以HMP45D传感器为基础的污染信息采集子系统和S3C2410核心处理器为基础的信息处理子系统两部分组成,每一子系统都可以单独使用,通过设计MMA7260的传感节点加速器接入节点克服由于跨区域造成的湿度传感器在中、高湿校准点出现超过最大允许误差的现象,以及设计了防信号冲突的软件设计,保证系统的实时性、易用性。在对某一气象染监测站的实验数据,根据IDATA平台进行测试显示,该系统能够大幅降低大区域内范围过大造成的信息失真的弊端,最大误差不超过1%,数据通信时间较短,保证了系统的实时性和良好的应用性。

Due to different regional pollution information relevance is poorer, the meteorological environment pollution index measuring equipment cannot be accurately detection of pollution in different areas of the information analysis, put forward a kind of meteorological envi- ronment pollution monitoring system based on Internet of things technology, the hardware and software design method are presented. System adopts hierarchical, modular, network structure of the Internet of things, by the pollution of HMP45D sensors based information collection subsystem and core processor S3C2410 based pollution sensor information processing subsystem of two parts, each subsystem can be used a- lone, by designing the sensor MMA7260 accelerator access nodes overcome due to cross-- regional humidity sensor, humidity calibration points in exceed the maximum permissible error occurs, and the signal of conflict prevention software design, ensure the system real--time performance, ease of use. In dye for a weather monitoring station of the experimental comparison results show that the system can greatly re- duce too much large area within the scope of information distortion caused by malpractice, the maximum error in the range, data communica- tion time is short, to ensure the real--time performance and good application of the system
