Research On Optimization Design Of Alarm System In Bus Under Malicious Conflict

In recent years,malicious conflicts on buses have occurred frequently,causing serious social harm and major economic losses.Therefore,improving the ability of alarming and emergency safety dispatch management of malicious conflict events in buses,so that buses can take effective alarm measures for malicious conflict events during operation.At present,the research on the alarm system in the bus is mainly carried out from the aspects of alarm technology optimization and emergency safety dispatch.However,there is a lack of research on the optimal design of the intelligent alarm system in the car under malicious conflicts.Therefore,the alarm problem of malicious conflict events in the car alarm system is optimized,and the defects of the existing public transport emergency alarm system are improved to provide relevant theoretical basis for the research of the intelligent alarm system in the car under the malicious conflict event.There are four main aspects of the research work of the subject: 1)The relevant theories,methods and principles of the alarm system in the bus are sorted out,and the relevant theories,methods and principles are sorted out from the aspects of bus safety,alarm service and alarm interaction design.The research content in the subsequent chapters find relevant research theories and methods;2)Using interactive design related theoretical methods,the in-car alarm and the in-car alarm service system are analyzed from information interaction,behavior interaction,and task interaction to establish equipment alarm information interaction Way;second,analyze the alarm behavior of the people in the bus,get the alarm behavior path and key contacts of the alarm behavior of different people in the bus;finally,perform task analysis on the alarm information and dispatch rescue in the bus alarm service system,Establish a mapping relationship model between alarm information and scheduled tasks.3)According to the structured interview,sum up the alarm demand of the malicious conflict event in the bus,and use the situation analysis method to analyze the relevant image data of the malicious conflict event in the bus,to obtain the relevant influencing factors of the malicious conflict event,according to the relevant influencing factors Design questionnaires and conduct surveys on behavioral and cognitive attributes,and statistical analysis found that the smaller the risk perception severity and perception barriers,the better the safety behavior;4)Define function points according to the alarm requirements and build an optimized way of the public transportation alarm and dispatch management system to The conceptual model of the intelligent dispatching scheme proposed here is finally evaluated for the design and usability and ease of use of the "vehicle alarm and intelligent display device".The conclusion is that the optimal design of the alarm system in the bus has a certain sense of feasibility for improving bus safety.The paper has 55 figures,34 tables and 86 references.
