Study On Synergy Mechanism And Mixed Navigation Risk Identification Of Conventional/Remote Control Ships In Inland River

With the development of high and new technology,the support of national policies and the need of international competition,ship intelligence technology has been greatly developed.However,due to the restrictions of current technology,environment and law,some scholars believe that remote control ships with remote driving will take the lead in navigation,and hybrid navigation between conventional ships and remote control ships with remote driving will inevitably occur in inland waters in the future.In this new scenario,many new security risks are bound to arise.In order to further promote the application of ship intelligence technology and improve the level of ship navigation safety in mixed scene,this paper studies the risk of inland mixed navigation of conventional/remote control ships,the main research contents are as follows:(1)Research on synergy mechanism of inland conventional/remote control ships.Based on literature review and expert consulting research,a collaborative framework for inland mixed navigation of conventional/remote control ships is proposed for the future scenario of inland mixed navigation.Based on this,the collaborative process of inland mixed navigation of conventional/remote control ships is analyzed and a collaborative mechanism for inland conventional/remote control ships is proposed,including collaborative perception mechanism,collaborative perception mechanism,collaborative decision-making mechanism and control mechanism.(2)Risk identification of inland conventional/remote control ships under collaborative mechanism.On the basis of collaborative mechanism of inland conventional/remote control ships,a system dynamic model of hybrid navigation risk of inland conventional/remote control ships is constructed.The key impact stages and key risks affecting the safety of hybrid navigation system are identified for bridge area scene,bending scene,dam area scene and narrow channel scene respectively.(3)Modeling and analysis of failure risk for collaborative decision-making of inland conventional/remote control ships.For the collaborative decision-making stage of inland conventional/remote control ships,firstly,a fault tree model of collaborative decision-making failure risk is constructed by using fault tree method to identify the key causes leading to the failure risk of collaborative decision-making.On this basis,the event tree model of failure risk of collaborative decision-making is further constructed by event tree method to analyze the possible main accident consequences.Finally,the Bow-Tie method is used to put forward targeted risk prevention and control strategies.The research on synergy mechanism and mixed navigation risk of inland conventional/remote control ships,motorised for inland remote control ship sailing rules and relevant safety regulations provide theoretical basis for,to form between conventional ship with remote control safety and efficient human model,motorised promote the development of the remotely piloted the ship has important social value and practical significance.
