【摘要】：目前，随着我国经济的高速发展，环境问题亦不断产生，环境保护工作日益艰巨，尤其是大气环境问题极为凸显，所以对大气环境监测的要求越来越高。物联网的快速发展及其实时高效等特性为大气环境监测提供了新技术以及新方法，使得大气环境监测克服了以往实时性差、维护困难等问题，能够实现更加实时、有效的大气环境监测。本文利用物联网的关键技术实现了一个大气环境监测系统，文中详细阐述了该系统的总体设计方案，系统由无线传感器网络以及远端服务器监测中心组成，其中无线传感器网络采用ZigBee网络和GPRS网络组合的方式实现，远端服务器监测中心运行的监测软件利用Microsoft Visual C++6.0编程实现。具体研究内容如下： 1)完成无线传感器网络中节点的软硬件设计，无线传感器网络包括网关节点和传感器节点，其中传感器节点以CC2530主控芯片为核心搭建，完成大气环境数据的采集以及通过多跳方式将数据传输至网关节点；网关节点由ZigBee无线通信模块、主控制器模块以及GPRS模块组成，是无线传感器网络的核心，以LPC2138主控芯片为核心搭建，网关节点的功能是完成组建ZigBee网络并汇总传感器节点数据，利用GPRS模块实现与远端服务器通信并上传数据。 2)远端服务器监测中心上运行的监测软件利用VC++基于MFC框架进行开发，能够实现与客户机(GPRS模块)通信、数据显示以及数据存储三个功能，其中利用套接字编程实现服务器与客户机(GPRS模块)的通信并接收GPRS模块发送的数据；利用MFC中提供的控件如编辑框控件以及列表框控件实现数据的显示；利用VC调用Excel接口实现数据存储。该监测软件为系统提供良好的人机交互界面，，大大方便了工作人员对历史数据的查看与分析。
[Abstract]:At present, with the rapid development of economy in our country, environmental problems are constantly arising, and the environmental protection work is increasingly arduous, especially the atmospheric environmental problems are very prominent, so the requirement of atmospheric environment monitoring is becoming higher and higher.The rapid development of the Internet of things and its characteristics of real-time and high efficiency provide new technologies and methods for atmospheric environmental monitoring, which can overcome the problems of poor real-time and maintenance in the past, and realize more real-time.Effective atmospheric environment monitoring.In this paper, an atmospheric environment monitoring system is implemented by using the key technology of the Internet of things. The overall design scheme of the system is described in detail. The system is composed of wireless sensor network and remote server monitoring center.The wireless sensor network is realized by the combination of ZigBee network and GPRS network, and the monitoring software of remote server monitoring center is programmed by Microsoft Visual C 6.0.The specific contents of the study are as follows:1) the hardware and software design of the nodes in the wireless sensor network is completed. The wireless sensor network includes the gateway node and the sensor node, in which the sensor node is built with the CC2530 main control chip as the core.The gateway node is composed of ZigBee wireless communication module, main controller module and GPRS module, which is the core of wireless sensor network.The function of gateway node is to set up the ZigBee network and collect the sensor node data, and use GPRS module to communicate with the remote server and upload the data.2) the monitoring software running on the remote server monitoring center is developed with VC based on MFC framework, which can realize three functions: communication, data display and data storage.The socket programming is used to realize the communication between the server and the client / GPRS module and to receive the data sent by the GPRS module, and the display of the data is realized by using the controls provided in MFC such as the edit box control and the list box control.Using VC to call Excel interface to achieve data storage.The monitoring software provides a good man-machine interface for the system and greatly facilitates the staff to view and analyze the historical data.
