Design Of Remote Electronic Control System For Plankton Segmental Trawl

The remote electrical control system for plankton layered trawling studied in this thesis refers to the advancement of ship towing equipment.The equipment will open the net at different sea depths and capture plankton in the water layer.The staff of the fishing boat can observe the equipment in real time.A remote electrical control system capable of controlling equipment in the deep sea on the water.Plankton has a certain distribution pattern.Studying its distribution law can guide people to find suitable fishing grounds and can also be used as an important reference for surveying petroleum resources on the sea floor.By analyzing the research status of plankton at home and abroad,the current equipment can only analyze plankton in real-time in a single water layer.This topic studies a remote electrical control system that collects multiple samples in the water at one time.The electronic control system is divided into three parts: underwater measurement and control system,deck computer,and data transmission system.The underwater measurement and control system uses the embedded OK335 x S as the core,and multiple sensors are connected to measure the operating conditions of the device,including the current depth of the device,the tilt angle of the device,and a net-down counter.Perform the operation of lowering the net clothes,and upload the information collected in real time to the upper deck machine through the communication module.The data communication module is mainly responsible for realizing the underwater and deck communication functions.The upper computer can switch the working mode of the underwater measurement and control system.The online mode can monitor the real-time status of the underwater measurement and control system in real time,and the operator will release the net clothes;the offline mode will make the system work automatically,and the status value of the underwater equipment cannot be monitored in this mode.Finally,the remote electrical control system for plankton layered trawling developed in this paper has completed relevant functional tests in the laboratory and functional debugging of each module of the workshop.The test results prove that the system has stability and reliability,and has been tested in the "Ocean One" The ship was successfully put into use and collected multilayer samples of plankton from the Western Pacific.
