摘要:
海洋资料浮标以其多种功能和连续探测能力成为现代海洋观测的重要工具。海洋浮标传感器种类多、通信协议差异性大，为浮标数据采集系统提出了集成应用需求多样、平均开发周期长的问题。本实验设计并实现了基于串行通信波特率特征判别传感器的通用型海洋浮标数据采集系统。系统基于串行通信接口，通过对波特率的自动识别，对多种不同海洋参数传感器的通信特点进行比对分析，从而将传感器进行分类识别，实现外载传感器的自动识别功能；通过IAP设计，实现系统的拓展。最后，通过实验室的原型试验进行技术路线可行性验证。结果表明，系统能够在数秒内快速无误识别信息库中传感器，可以通过分包方式满足远程更新需求。

Abstract:
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.
