A real-time monitoring system for oceanographic parameters based on GPRS technique

This paper presents a real-time monitoring system which is comprised of field data logging subsystem, wireless communication subsystem and on-station control center. The real-time monitoring system is applied for field data acquisition of marine environmental parameters, so as to provide key data for research both on the prediction and the cause of marine hazard. The wireless data transmission technique based on GPRS (General Packet Radio Service) facilitates the application of the system, since it eliminates the complexities of arranging wire and wire maintenance. The results of system trial in-situ proved that the real-time monitoring system is feasible and it can perform efficient monitoring of the marine environment
