Design of embedded software for in-situ monitoring system of marine radioactivity based on a buoy

The in-situ monitoring of marine radioactivity can be continuous, real-time and automatic, compared with traditional on-site sampling and then laboratory analysis. The marine radioactive data are larger in volume and longer transmission time, compared with the traditional sensor data. If the marine radioactive data are incomplete, it will cause parsing spectrum errors. A method of sending data using multiple packets and resending lost packet data is designed and tested in this paper. After the test, the method of resending data was optimized, remote modification of marine radioactivity monitoring system measurement parameters and sleep mode were added. Finally, the system can monitor marine radioactivity with a long time, continuously, automatically and low power consumption by long-term testing.
