The Design Of General Data Transfer Platform Based On Gprs

GPRS as a mature technology of wireless transmission,has been widely used in the filed of military, industrial, commercial and scientific research ,and so on. General data transfer platform based on GPRS, as a portable embedded systems, can be used as remote monitoring,static image transmission, environmental information monitoring,POS business terminals and another wireless GPRS hardware platform. The function of this platform can be through the target wireless data transmission, real-time transmission to the control center for display and control.Is is the main development trends for GPRS to realize transmission of small amount and real-time datas.The paper introduced common structure of data transmission platform Based on GPRS, as well as relating technology,sunch as the GPRS communication technology, GPS positioning technology and image compression technology.Using PC and debugging templates, take measures to eliminate redundant design approach based on the AT command ,achieve the GSM communications and GPRS communications, and data transmission on the common platform for the simulation of the feasibility.in order to facilitate the realization of the monitoring center and terminal interactive communications, developed a communication protocol; elaborate a common platform for data transmission design, the design of the main include GPRS module, GPS data acquisition module, JPEG image data acquisition module and the external RAM memory modules to expand the functions of the various modules and external a specific description of the circuit to produce a data transmission platform of PCB board; completed the software design platform, including the MCU application design software, GPS positioning data acquisition, JPEG image data acquisition and environmental information collection software. Into system design and summarized, to make some improvements.
