草原生态远程监测系统的设计与实现

Design and Implementation of the Remote Monitoring System of Grassland Ecology

分析了无线通信GPRS(General Packet Radio Service)和微处理器DSP技术,提出了基于GPRS的草原生态远程监测系统设计方案,论证了一种基于DSP微处理器和GPRS网络通信技术实现远程数据传输的系统,从而实现远程数据和图像的实时监测功能.本系统的核心内容是通过TMS320LF2407A DSP控制图像、温度、湿度、风速等传感器采集数据,并将采集到的数据送到GPRS DTU(GPRS Data Transmission Unit),最终通过GPRS、Internet网络传送到控制中心,控制中心将收到数据存储,并恢复出原图像.

The GPRS（General Packet Radio Service） of wireless communication system and the DSP microprocessor technology are introduced.A design project of remote monitoring system of grassland ecology based on the GPRS is proposed.A data transmission system,which performs real-time data and image monitoring,and achieves long-distance data transmission based on DSP and GPRS network communication technology,has been argued in this project.The core of the system is to collect image,temperature,humidity and wind speed data through the corresponding sensors under the control of TMS320LF2407A DSP.These data are sent to GPRS DTU（GPRS Data Transmission Unit） and ultimately sent to the control center,in which the data are stored and the original image is restored,through the GPRS and Internet.
