GPRS based data acquisition and analysis system with mobile phone control

Wireless based data acquisition solutions are the focus of many researchers and have a huge impact in domains like structural analysis, medical telemonitoring, transportation or environmental studies. This paper presents an experimental General Packet Radio Service (GPRS) based remote data acquisition and analysis system which offers mobile phone control possibilities. Sensor voltage variations are sampled by the TI MSP430F2274 microcontroller and transmitted to a Web Server using the Cinterion MC55iT GSM/GPRS terminal. Collected data are available to authorized users, for visual inspection and analysis, by both a LabVIEW application and a mobile phone web interface. If recorded data values exceed established control limits the terminal is automatically instructed to send warning messages via Short Message Service (SMS). Experimental results performed over several weeks prove that the presented instrumentation was properly designed and implemented.

► Is capable of connecting to the information Database hosted by the Web Server.
► GPRS based transmission is implemented.
► Calculations can be customized according to user specifications.
► Error messages are displayed if the server cannot be accessed.
► Synchronization with the transmission from the GPRS terminal is implemented.
