海洋剖面信息对于指导渔业生产非常重要，尤其是了解海洋温度、深度和盐度等关键参数，这对渔业生产者快速掌握目标鱼种的海域环境及其变化趋势具有重要意义。研究并开发了一款面向远洋渔业生产作业的高效温深盐仪(conductivity，temperature and depth，CTD)数据处理系统，通过与CTD设备直接通信，实现即时传输和实时分析海洋温度、深度等关键参数，为渔业生产提供决策支持。该系统采用树莓派4B作为硬件平台，使用Python语言进行开发，结合Matplotlib库实现数据的可视化功能。系统通过RS232/RS485数据接收模块与CTD仪器进行通讯，实时传输和分析海洋数据，并提供判断温跃层和特定水温深度的功能。该系统显著提升了海洋剖面数据的处理和查询效率，使得渔业生产者能够更加精准地进行捕捞，大大提高了渔业生产中的决策效率。此外，该系统的便携性和操作简便性使得非专业背景的渔民也能轻松使用，使渔民能够充分利用现有科技进行捕捞，切实体验到科技带来的便利和效益。通过高效CTD数据处理系统，渔业生产者不仅能够更快、更准确地获取关键海洋数据，还能及时调整捕捞策略，提高捕捞成功率，最终实现渔业生产的可持续发展。
Efficient CTD data processing system design based on Raspberry Pi 4B
Ocean profile information is crucial for guiding fisheries production,especially in understanding key parameters such as ocean temperature,depth,and salinity.This information allows fisheries producers to quickly grasp the environmental conditions and changing trends of the habitat oftarget fish species.The paper aims to develop an efficient conductivity,temperature and depth(CTD)data processing system for distant-water fisheries operations.The system directly communicates with CTD equipment,enabling instant transmission and real-time analysis of key ocean parameters,thus providing decision support for fisheries production.Using Raspberry Pi 4B as the hardware platform,the system is developed with Python and incorporates the Matplotlib library for data visualization.It communicates with the CTD instrument via RS232/RS485 data reception modules,transmitting and analyzing ocean data in real-time.Additionally,it provides functions for detecting thermoclines and specific water temperature depths.This system significantly enhances the efficiency of ocean profile data processing and retrieval,enabling fisheries producers to carry out more precise fishing operations and greatly improving decision-making efficiency in fisheries production.The system's portability and ease of use also allows fishermen with non-technical backgrounds to easily operate it,enabling them to fully utilize existing technology for fishing and experience the convenience and benefits it brings.With this efficient CTD data processing system,fisheries producers can obtain key ocean data more quickly and accurately,allowing them to promptly adjust fishing strategies,increase fishing success rates,and ultimately achieve sustainable fisheries production.
