Design Of Software Interface Of Ship Main Engine Monitoring System Based On Situation Awareness

As the world continues to attach importance to and rely on marine resources,competition in the shipbuilding industry among countries has become increasingly fierce.As a powerful country in maritime construction,the importance of shipbuilding industry development is self-evident.The ship main engine monitoring system is the core part of the ship,which always guarantees the safe and efficient operation of the ship.As the communication medium between human and machine,the main engine interface constantly monitors the operation of a large number of complex equipment.However,due to the lack of comprehensive consideration of situation awareness in the current design of domestic ship main engine monitoring interface,the operator requirements to browse and switch multiple windows to perceive data during monitoring operations,and then integrate the information to understand the overall system situation and make predictions and judgments.The entire process consumes large amounts of memory and cognitive resources throughout the whole process,greatly affects the decision-making level of the operator.In response to this situation,this thesis starts from the situation awareness of humans,comprehensively analyzes the situation awareness and cognitive mechanism of the operator during maritime monitoring operations,sorts out the situation awareness information requirements of the operator during typical target tasks Summarize the design principles of the ship main engine monitoring interface from the perspective of situation awareness,and optimize the design of the original interface from the perspective of information demand presentation and layout optimization to improve the situation awareness level of operators in complex dynamic situations.The main research work of this thesis is as follows:First of all,starting from the theoretical background of situation awareness,this thesis explores theories and models of situation awareness,then analyzes the characteristics of variables that affect the operator’s situational awareness from the three aspects of human factors,tasks and environments;This thesis analyzes from the visual attention representation level that affects situation awareness and the perspective of information processing,and proposes the situational awareness cognitive process of the ship main engine monitoring system software interface.Secondly,based on the cognitive mechanism of situation awareness,the GDTA method is introduced to extract the situation awareness information needs of operators during typical monitoring operations,and visual design principles of information elements of ship main engine monitoring interface are proposed from the perspective of ‘perception-comprehensionprediction’,so as to provide guidance for interface design.Thirdly,this thesis sorts out the typical target task flow of the main engine monitoring interface,disassembles the functional information in combination with the multi-level information requirements of situation awareness,and establishes an information organization structure that conforms to the operator’s situation awareness mechanism.Based on the design principles and methods of the ship main engine monitoring interface of situation awareness,the visual elements and layout are optimized,and the Axure tool is used to complete the dynamic interactive prototype design of the optimized interface.Finally,this thesis constructs the ship main engine monitoring system interface evaluation index system,and uses the subjective and objective evaluation method to comprehensively evaluate the multi-dimensional situation awareness before and after the optimization of the ship main engine monitoring system.so as to verify the effectiveness of the software interface design method of the ship main engine monitoring system based on situation awareness.
