Title The Design Of the Remote Data Acquisition And Transmission System
Based On GPRS Network
Abstract
Along with the fast development of wireless communication and the microcontroller technology, the long-distance communication solution is also having the change unceasingly. Take this as the research background，mainly discussed and designed one realization plan of the remote data acquisition and transmission system based on GPRS network communication .We select the AD22100 temperature sensor to carry on the data acquisition; use the C8051F020 microcontroller to control and process the data ;At the same time, the microcontroller connects with the GPRS module (MC35i) which contains TCP/IP stack through the UART ,and uses the AT orders to realize the initialization and the control of GPRS module; Finally, dates are transferred to the far-end monitoring center through GPRS network and Internet .It mainly involved the design of terminal hardware and the transformation of the transport protocols. For the remarkable advantage of GPRS communication technology applied to middle and low speed rate date transmission, GPRS wireless data acquisition system is of high feasibility and high performance price ratio. The scheme is all-purpose and can be applied to many fields, such as industry control, finance industry and transportation .etc. The design of remote data acquisition system based on GPRS service will be of vast prospect of development.
