基于GPRS/SMS空气污染远程监控系统的设计与实现

为了实现空气质量指数的智能监测和管理,设计并实现了一种基于SnO2人工嗅觉探测的空气质量指数监测系统,系统通过空气质量指数现场网络监测节点采集、处理以及传递空气质量指数数据,采用ARM S3CA510B进行DTU数据传递,实现空气质量指数数据CO、SO2等的高效率、大批量的传递；使用汇聚节点模块通过GPRS网络将数据传递到监管终端,监管终端将管理命令通过GPRS网络反馈到汇聚监测节点,实现空气质量指数数据的远程监测；采用监测管理终端为管理人员提供不同的监测处理、控制处理以及空气质量指数监测相关数据检索和汇总分析等人机界面。对系统空气质量指数信息流的传递流程图进行了设计,给出了系统数据通过串口进行通信的代码以及系统监管终端使用套接字实现网络通信的核心源码。实验结果说明,与传统系统相比,所提系统可实时监测出空气中CO、SO2等污染气体的浓度,具有很高的实用性及有效性。

Design and Implementation of Remote Monitoring System of Air Pollution Based on GPRS/SMS

In order to realize intelligent monitoring and management of air quality index, designs and realizes a kind of index of air quality monitoring system based on SnO2 artificial olfactory detection, the system through the air quality index field acquisition, processing and transmission network monitoring node air quality index data, using ARM S3CA510B DTU data transmission, air quality index data the transmission of high efficiency, large quantities of CO, SO2, etc; Use gathering node module through the GPRS network to pass data to the regulatory terminal, regulatory management command through GPRS network terminal feedback to convergence monitoring nodes, to realize the remote monitoring of air quality index data; The monitoring terminal for management personnel to provide different monitoring treatment, control and monitoring air quality index related data retrieval and summary analysis of man-machine interface, etc. Air quality index of the system flow chart of the flow of information transfer has carried on the design, system data through the serial port communication code are given and the system monitoring terminal use socket implementation of network communication core source code. Experimental results show that, compared with the traditional system, the proposed system can real-time monitor the concentration of CO, SO2 pollution gas in the air, has the very high practicability and effectiveness.
