GSM GPRS Communications

    The GSM Modem includes an integrated GPS Modem. Therefore, the station antenna is GPS which not only keeps station time accurate but eliminates the need for two separate antennas. The Sutron antenna is an integrated unit that receives GPS signals as well as Quadband RF signals.
    • Provides real time data from current hydro-met measurements to users of GSM/GPRS networks.
    • Robust, reliable, broad-based GSM/GPRS communication system that sends data in text & image formats.
    • The GSM/GPRS network automatically gathers data as & when needed at user-defined time intervals and stores the data in the Server for analysis.
    • Stations are configured to call the Server phone at user-specified times to transmit the GPRS message. If the transmission isn’t successful, the station will retry transmission for a user-defined number of times. If the transmission in GPRS mode fails after x number of retries, each station switches over to GSM mode to transmit data.
    • Each station includes a GSM/ GPRS control terminal with everything needed for wireless M2M capabilities & to avoid delay in data reception caused by network congestion.
    • Each GSM/GPRS RTU sends an automatic message at user selected intervals ( i.e., every 10 minutes) to the Server. Sampling is programmable at intervals, 0 to 60 minutes.
    • Data is transmitted in ASCII format to a Central Server. Data can also be routed to an e mail address or sent as a UDP packet in GPRS to an address and port, that can be programmed via SMS.
    • Each station can log & store data locally in flash memory, then later retrieve detailed logs.
    • The Central Server has the ability to answer calls & communicate data using a synthesized voice (any language needed).
    • The System also responds to SMS requests for current data.
    • Provides automatic SMS alarms set at programmable levels for any parameter needed.
    • Sutron also provides System Software to manage the GSM/GPRS Network for troubleshooting & to return functionality in order to dramatically minimize down time.
    • The System can display data & export data to Excel, Matlab & similar applications for graphical representations.
    • Both the Server & Station Data Loggers are programmed to provide event-triggered information & alarms for sudden developments such gusts, squalls, thresholds of rainfall, rise in water level, current changes, etc.
    • All data received in the Central Server is in standard exchangeable RDBMS format using SQL Server or Oracle. Each Station has the facility to be queried at any moment or at any intervals, regarding any parameter or sensor. GUI Server Software includes a statistical tool.
