基于GPRS无线传感网的大气CO_2浓度采集系统研究与设计

GPRS Wireless Sensor Network based on Atmospheric CO_2 Concentration and Design Collection System

针对实现大气中二氧化碳浓度的及时快速采集,设计了基于GPRS无线传感网的大气二氧化碳浓度采集系统,系统分为数据采集终端、GPRS无线传输网络和数据中心3部分。数据采集部分主要由单片机、高精度二氧化碳传感器、GPS模块、GPRS模块和液晶显示模块组成,负责采集二氧化碳浓度和采集点地理定位信息;无线传输网络部分由GPRS模块接入到GPRS网络,再登陆到Internet网络与检测中心服务器建立TCP网络连接,负责将采集到的数据传输给数据中心;数据中心主要是接受GPRS网路传输过来的数据,并将数据进行处理、显示和录入数据库。采集系统能摆脱数据采集时地理位置和天气条件上的局限性,使检测工作变得更及时方便准确。

To collect the Carbon dioxide concentration of atmospheric rapid and timely, we designed the Carbon diox- ide concentration of atmospheric, GPRS-based wireless sensor network, capture system. The system is divided into three parts, data collection terminal, GPRS wireless network networks and data centers. The data collection terminal is composed by microcontroller, carbon sensor, GPS module and liquid crystal display modules, capturing carbon dioxide and geographic location information. The wireless network access to the GPRS network though the GPRS module first, then log into the internet network and testing center to establish a TCP network connection, transmit- ting the data to the server. The data center is to accept data transmitted over the GPRS network, and process the data, display the data and entered it into the database. The collected data acquisition system can get rid of location and weather condition limitations, make the testing work becoming more convenient and more accurate.
