The bridge is the main part of the navigation control and combat command in the superstructure of the ship.With the promotion and popularization of emerging technologies,the integrated bridge system(IBS,Integrated Bridge System)with higher integration and richer functions can replace the traditional various independent navigation And navigation aids to achieve the purpose of streamlining personnel and bridge space and improving control efficiency.But it will also lead tnumberncrease in the number of work tasks undertaken by a single person and an increase in the cognitive load,which puts forward higher requirements for the ergonomic layout and display interactive interface of the IBS.Reasonable IBS ergonomic layout and display interactive interface design has important significance and broad application prospects for navigational operation efficiency and navigation safety.The crew mainly obtains the required information and performs operations according to the navigation task process.Therefore,this article is guided by the task process and uses ergonomic simulation technology to optimize the layout and display interface of the integrated bridge system.The research object of this paper is the IBS of a certain type of hovercraft.First of all,this paper conducts simulation experiments on the navigation task of the research object,to obtain the specific operation steps of each crew member and the cognitive resources occupied by the execution,and then uses the Petri net method to build the navigation task process model.Analyze the cognitive load of each crew member in each task stage according to the task process model,and propose solutions to reduce the high cognitive load task sequence.Secondly,Jack software is used to build the IBS three-dimensional simulation environment,and the digital human body simulation operation actions are set according to the task process model.With the help of relevant simulation evaluation tools,the problems of unreachable operation and uncomfortable joints of digital human bodies of different sizes in the task process are analyzed.According to the analysis results,the IBS ergonomics optimization strategy is proposed.Finally,the IBS display interactive interface and ergonomic layout are optimized based on the optimization of the cognitive task process and the results of ergonomics simulation.The evaluation results show that the optimized IBS can meet the operation and use of crews of different body sizes,which greatly improves the operating comfort.The main innovations of this paper are: at the theoretical level,it explores the method of constructing the ship navigation cognitive task process model,analyzes the crew’s cognitive process and physiological movements at the same time,and proposes optimization strategies,providing new ways for the optimization of complex information system interfaces.Methods and ideas.At the implementation level,the IBS optimization design strategy is proposed and practiced,expanding the idea of ship IBS design and promoting the application and development of ergonomics in ships. |
