Abstract:

The drifting buoy is a monitoring device for real-time collection of marine hydro-meteorological and ecological environment data. It features small size, low power consumption and easy deployment, playing a significant role in marine observation. According to the working principle of the drifting buoy, a new type of real-time monitoring system with automatic retransmission mechanism and the software implementation method were designed in this paper. The system used BeiDou III communication method and has functions of sending instruction, data reception, storage, decoding, display, and automatic retransmission, it uses the flexibility of the queue to expand the retransmission range. After theoretical research and statistical analysis of test data, the results show that the new automatic retransmission mechanism can effectively improve the success rate of data recovery, and verify that the automatic retransmission mechanism in the real-time monitoring system has certain reliability and efficiency, providing reference for the subsequent design of real-time monitoring system in drifting buoy.
