基于gprs的环境监测网络系统研究与实现.pdf

摘要
近年来,我国科技迅猛发展,工业化程度不断提高,但自然生态环境却遭到了
越来越严重的破坏,因此,政府部门决定加大污染物排放的监控力度,建设全局性
的环境监测网络。
环境监测点通常位置分散、地理条件复杂、无人值守,因此人工抄取各监测点
的数据很不方便、执行效率低,有线方式收集各监测点的数据投入大、布线麻烦、
传输距离有限,因此需要一种适宜环境监测特点的数据传输方式来解决监测点数据
的收集问题。同时,环境监测工作具有很强的全局性,经常需要调用不同环境监测
区域的数据来做参考,但是现在没有一个好的环境数据交互平台。
针对上述情况,研究并设计了一种基于 GPRS 的环境监测网络系统,该系统分
两部分来实现。其一,设计了环境监测区域内部网络。该网络由监测点的环境监测
仪和监测中心的计算机构成。采用基于 ARM 的 S3C44B0X 芯片为核心设计了监测
仪的硬件电路,在μClinux 环境下进行了监测仪应用程序的开发,通过 MC35i模块
实现了监测仪的 GPRS 网络连接和与监控中心计算机的数据通信,解决了监测点数
据的收集问题。其二,设计了全局性的环境监测网络。该网络由各区域监测中心的
计算机构成,采用 B/S(浏览器/服务器)结构进行设计。对 Web 服务器进行了配置,
实现了静态和动态数据交互功能,满足了环境监测的全局性要求。
系统已经应用在省级的环境监测工作中,形成了以地、市和大型企业为环境监
测区域的全省性的环境监测网络,监测点数据上传及时、准确,监测区域间信息交
流通畅,很好地满足了全省环境监测的要求。

Abstract
Recently, in our country, science and technology was developed rapidly, the stand of
industrialization has great improvement. But, the environment was destroyed more and
more seriously. So the government decides to control the emission of contamination more
strictly and build work of environment monitoring in whole region.
There are many characteristics to the spots of environment monitoring, such as
dispersed, diversiform of geographical condition, nobody guard and so on. Now many
systems of monitoring get the data through manpower, that is waster time and inefficient,
others systems of monitoring get the data through munication wire, that has many
bothers in collocating wire and can’t translate remotely. So it is necessary to find a method
to transfer data. At the same time, the work of environment monitoring is often necessary
transferring the data in different region. But now there is not an effectual flat for
transferring the information between the regions of environment monitoring.
For the characteristic of the environment monitoring, this thesis researched and
designed work system of environment monitoring based on GPRS. This system was
realized from two aspects. One aspect is that an work was designed i
