Research And Evaluation Of Interface Design Of Low Speed Diesel Engine Exhaust Gas Desulfurization Monitoring System

With the rapid development of global trade,the number of ocean-going ships has increased rapidly,and the pollutants such as SO_X in the exhaust gas of marine diesel engines have caused increasing harm to the global environment.In order to prevent SO_X pollution,the International Maritime Organization(IMO)has formulated strict emission regulations.In order to respond to the regulations of ship exhaust emission and protect the ecological environment,it is an effective desulfurization method to install exhaust aftertreatment devices.The monitoring system is an important part of the exhaust gas desulfurization device.Due to the complexity of the exhaust gas desulfurization process,there are many factors that affect the desulfurization efficiency.Therefore,the control and operation process of the desulfurization device are displayed in front of the operator in the form of an interface to monitor the desulfurization device.Based on the ecological interface design theory,this paper analyzes the monitoring interface of the marine diesel exhaust gas desulfurization system,and optimizes the interface design to improve its usability.For a company’s ship exhaust gas desulfurization control system,a set of desulfurization system monitoring interface is designed in combination with the ecological interface design theory.This article mainly designs and studies the software interface of the ship desulfurization monitoring system from the perspective of ecological interface design.First of all,through literature research and comparative analysis methods,the relevant domestic and foreign research results and listed products are analyzed and researched,so as to find the deficiencies in the design of the software interface in China.Secondly,through summarizing and studying the specific methods of ecological interface design,the specific steps of desulfurization monitoring interface ecological interface design are obtained.Then,through the research and analysis of the existing specifications,standards and principles of the software interface,and summarizing the design specifications,principles and methods of the software interface of the ship desulfurization monitoring system in the three aspects of information architecture,interface layout and graphic color design.Thirdly,based on the completed ecological interface design specifications and the relevant design specifications,principles and methods of the ship desulfurization monitoring system software interface design and practice,complete the ship desulfurization monitoring system software ecological interface design.Finally,using the constructed desulfurization monitoring interface cognitive load evaluation index system to subjectively evaluate the desulfurization monitoring interface cognitive load before and after optimization,the optimized ship desulfurization monitoring system software interface has lower cognitive load and higher availability level.in conclusion.
