Design And Implementation Of The Grassland Ecological Monitoring System Based On GPRS

Since overloading the animal husbandry, artificially reclaiming the grassland, global warming and other factors, the grassland ecological environment has been seriously damaged. The grassland desertification and degradation is serious.Howerver, now people have gradually realized that the grassland ecological environment for sustainable human development is important. So people take active measures to control the grassland ecological environment and to restore the grassland ecological environment. The grassland ecology workers in the grassland ecological restoration process play an important role. The grassland ecological monitoring system serves the grassland ecology workers in order to provide them with accurate, full and accurate information for scientific research.This paper analyzed the GPRS wireless communication and DSP microprocessor technology and proposed overall design plan based on GPRS. This paper major demonstrates through the DSP microprocessors and GPRS network communication technology to attain long-distance real-time, monitoring data and images. The system is the core content that the TMS320LF2407A DSP controls to collect images, temperature, humidity, wind speed and other sensor data. The DSP collects the data and sends to the GPRS DTU (GPRS Data Transmission Unit).Finally the GPRS DTU sends the data to the control centre through GPRS and INTERNET network. From the structure, the paper first introduced the TMS320LF2407A DSP as the core hardware platform (minimum system).And discussed the image module of C328 on principle, interface circuit and control procedures. Also on temperature, humidity and wind speed sensor the paper gave an outline of the principle and discussed principle, network scheme and configuring approach of the GPRS DTU. According to the functional goals and performance requirements of the monitoring system, the paper proposed the overall design of the control centre programs. Finally the paper briefly summarized the contents of this article and put forward a number of existing problems in design, which hope gradually improving in subsequent studies.
