Design of automatic sensor identification and universal buoy data acquisition system based on serial communication

Marine data buoys, with their multiple functions and continuous detection capabilities, have become an important tool in modern oceanic observations. The availability of various marine buoy sensors and significant differences in communication protocols create diverse application requirements and increase the average development periods of the buoy data acquisition control system. In this experiment, we designed and implemented a universal ocean buoy data acquisition system using a feature-discrimination sensor and serial communication baud rate. The system, which was based on a serial communication interface, worked through the automatic identification of baud rate and comparison of the communication characteristics of various ocean parameter sensors. The sensors were classified and identified to realize the automatic identification function of an external load sensor, and system expansion was achieved through IAP design. Finally, the feasibility of the technical route was verified by a prototype test in the laboratory. Results showed that the system can quickly identify the sensors in the information base within a few seconds and can meet remote update requirements through subcontracting.
