Design And Implementation Of 3D Emergency System For Petrochemical Fire

The focus of the petrochemical industry as the national pillar industry has a vital role on national economy. Because oil chemical enterprise has its particularity and extinguishing fire accident rescue mission has a great risk, so the appropriate fire emergency plan system becomes the effective way and important work to prevent accident and play emergency rescue. Traditional emergency plan system are mostly based on the theory support of words, pictures and video etc. Its practical operational line is poor and it is difficult to meet the requirements of control accidents. Relative to the emergency plan system, also the traditional practical training methods to avoid the accident has a lot of problems and limitations, such as have certain risk, training will consume large amounts of manpower material resources and other issues. At the same time subjecting to the conditions of plant equipment and personnel seriously affect the enterprise normal production activities. With the rapid development of computer software and hardware technology, which brings a revolutionary innovation for petrochemical fire drill and petrochemical accident treatment which is the use of virtual reality technology to simulate actual combat command and skills training environment and to make decisions. This new technology is mainly based on network technology, information technology and virtual reality simulation technology as support, which solved the previous training pattern and disadvantages that exist in the accident disaster survey and assessment. Because the 3d emergency plan system has so many advantages, many enterprises at home and abroad research institutes have launched the research. And how to maximize the emergency response plan in practical applications, and construction of three-dimensional fire emergency plan and management, it is worth to study further and discuss more.In this paper, the success of applying virtual reality technology, computer technology and Artificial intelligence technology in petrochemical industry fire drill, fire based on the construction of spatial database system, combining with the self-developed platform i4-Factory, adopts advanced high speed 3d rendering engine technology, simulation and analysis for the accident, fire activity abstract modeling, the construction of fire emergency plan and management, Intelligent generating methods of contingency plan, to do a lot of research, set up 3d emergency plan system for petrochemical industry. The main research includes:(1) To design a set of easy extension and strong compatibility level platform application system overall architecture, the platform can be divided into several different levels; The basic flow of designed for platform data; To design a set of suitable for the platform of high safety fire database system.(2) Studying the model and simulation visualization analysis algorithm of the accident. Through the introduction of particle system such as high speed rendering technology, real-time simulation of the accident basic form and change tendency; By applying the mathematical analysis model, in view of some types of accidents made numerical value simulation and analysis of the auxiliary aid decision making.(3) According to the deployment of petrochemical and fire fighting forces, will be involved in element and the fire in the real world task abstract concept in the world, established the role of fire and fire fighting action model, and further instantiate the role and action. Users with a single or a series of selection and movement function matching fire mission, role system provides users with virtualization fire drill visualization operation platform.(4) According to the multiple role model of basic establishment, system research and development program logic editor that provides users with visual plan generated editing methods. Through the study of the research of artificial intelligence technology, try to realize intelligent generating methods of contingency plans. Plans for building, the system provides the plan play control mechanism and plan evaluation method, through the humanized interactive plan view and plan to make an effective assessment according to the actual demand, can change the problems of plan targeted, can also be in accordance with demand plan system as a classic case in the plan to extend the system functions.The innovation of the system design point mainly reflects in:(1) By studying the fire fighting and the task force, bold and build from real world to bit world fire model, and the method of using visualization operation panel for the first time to edit the generated three-dimensional contingency plans, and provides users with all-round, multi-angle, humanized interactive way to check the operation plan, completed the traditional textual plans to digital transformation plan of the information.(2) Based on i4-Factory platform rendering engine mechanism, set up a virtual physical environment has a variety of types of petrochemical plant model, using CUDA high-speed parallel algorithm, to a variety of mathematical physical model used in the fire emergency plan.(3) The bold attempt the artificial intelligence technology in the application of fire emergency plan and discussed the man-machine interactive intelligent plan generation and the intelligent method of fire plan drill.
