Research on the Visualization Method of Emergency Disposal Process of Urban Rail Transit Based on Information Element Structure Coding
In order to solve the problems of large amount of information and confusing structure level when visually displaying complex business process,this paper proposes a hierarchical visualization method based on information element structure coding.Taking the power loss disposal process of catenary in rail transit as an example,firstly,this paper constructs the topology of information element network,transforms the relationship between"operation task-information graph element"into the quantitative data associated with"information graph element-information graph element",and establishes the comprehensive importance evaluation index for information graph element network nodes,to realize the hierarchical division of key information display of complex business processes,and eye movement experiments are designed for the division results.The experiment shows that the interface search based on the hierarchical information element structure is more efficient,the cognitive load of users is reduced,and the performance of task operation is improved,which verifies the rationality and effectiveness of the proposed method.
