Design And Development Of 3D Visualization System For Emergency Plan Of Oil And Gas Transmission Pipeline

With the rapid development of long-distance oil and gas pipelines,oil and gas pipeline accidents occur from time to time due to the increasing age of pipelines,construction defects,corrosion and human damage,which bring serious losses to the national people’s safety and economy.Therefore,it is imminent to establish a perfect emergency rescue system and emergency plan,and organize timely,standardized and effective emergency rescue drills.In the actual emergency process,the traditional text pre-plan drilling is limited by time,space and economic costs and other factors,can not be carried out high-frequency,fast and effective.At the same time,the number of emergency pre-plans is large,update faster,through fixed visual emergency pre-plan can not be exhausted,so it is necessary to establish a set of accident-based scenarios.Editor’s digital preplan editing and deduction system.The three-dimensional visualization compilation system of oil and gas pipeline emergency plan is based on the emergency plan.It uses the emergency resource database to customize the drilling scene.Through the combination of reality and system scene,it builds a platform which integrates scene editing,digital pre-plan editing and three-dimensional visualization deduction of pre-plan to achieve the goal.To drill,check,verify and improve plans in the normal time,and guide the purpose of emergency rescue.This paper mainly designs and develops three functional modules: digital pre-plan editing system,three-dimensional scene editing system and three-dimensional visual pre-plan editing and deduction.Digital pre-plan editing is based on the traditional paper pre-plan,extracting the organizational structure of the emergency plan,emergency resources,emergency process stage,evaluation criteria and other information,digitally editing the content of the pre-plan,realizing the transformation from paper pre-plan to digital pre-plan.The 3D scene editing system provides three-dimensional scene environment support for all three-dimensional systems.The three-dimensional plan deduction system mainly includes three-dimensional plan effect editing and three-dimensional plan deduction.The digital pre-plan/drill script can be transformed into 3D visualization and interactive 3D pre-plan executable script by 3D effect editing function,and 3D pre-plan executable script can be deduced by 3D pre-plan deduction function.With the use of 3D visualization technology and the introduction of free configuration of modular development idea,the emergency plan involved in the scene,accident type,accident disposal and reconstruction and other aspects of modular development,providing open platform free calls,any combination for the user,the maximum extent to meet the personalized needs of different users of emergency drill,improve emergency rescue drill effect,reduce the cost of development.
