On-site observation in the marine environment is required to obtain real and reliable data for research on marine microorganisms. This article presents an automatic seawater sample collection and distribution system for ships based on the NI CompactRIO. The system is deployed on scientific research vessels and establishes connections with instruments such as the winch system at the stern of the vessel and microbial flow image analyzer, under the control of the management system, achieving fully automatic or semi-automatic extraction, filtration, transportation, and automatic cleaning of the entire pipeline of seawater samples. The system can also monitor various water quality parameters such as temperature, salinity, dissolved oxygen, conductivity, chlorophyll, etc. online and upload to the system for storage. The system is designed based on a reliable and stable embedded hardware system, which is conducive to long-term operation in marine environments, maximizing the preservation of the original appearance of seawater samples, and ensuring the authenticity and effectiveness of analysis and detection data.
