Research Of The Grassland Ecological Remote Monitoring System Besed On GPRS

Technology of data capture has been used in many fields along with the developing of science and automatization technology. It Provides more effective inspector industry and makes human life safer and more convenient.Advanced technology of GPRS wireless network transmission is applied in the remote wireless data capture system based on GPRS technology. Data of image can be transmitted through wireless network of GSM in existence. The system can be used in most occasions without special equipments, specially in the occasion that netwokr with cable can not be paved.Data capture terminal of the whole system is composed of control circuit based on DSP ,image sampling module, temperature and humidty sensor,wind speed sensor and GPRS network transmission module . Images are compressed and encoded with JPEG standard by hardware to reduce the transmission quantity of image data. In order to meet the system requirements, we apply GM8125 to serial expansion by DSP.TMS320LF2407A DSP and 74LVC4245A device is used in system hardware. This structure can connect the high speed part of data process , data memory and data capture with the low speed part of data transmission. Modules with general standard interface are used in the data capture system. various sub-functions is completed through DSP in-chip peripheral module.The performance is increased with the reduce of system complication.Users can capture the data of the actual scene, and can also inspect and control it remotely whenever and whereever.
