Research On The Simulation Platform Design For Generator Set Fires In Hydropower Stations Based On MR

With the development of Mixed Reality(MR)technology,the traditional emergency drill in enterprises is gradually transferred to digitalization and virtualization,which visually presents the invisible emergency drill process and broadens the boundary of emergency drill training mode.It enables operation and maintenance personnel to interact in real time with the virtual image superimposed on the real scene through the MR Device,and intuitively feel the authenticity of the accident,so as to improve their professional quality and on-site emergency response ability.However,at present,there are few researches on the application of MR Technology in the field of emergency drill.In the digital world constructed by MR Virtual image,there is a lack of specifications to guide relevant design,which leads to confusion in the process of operating MR Virtual image.Therefore,how to apply MR Technology to the simulation platform of hydropower station special emergency plan exercise is the focus of this research.Firstly,this paper analyzes the current situation of virtual simulation technology applied in the field of safety training at home and abroad,draws the research direction of this topic,summarizes MR Technology,and analyzes the problems that need to be considered in MR Design.Secondly,a field visit to the hydropower station was conducted,and the specific process of the special emergency plan drill for the generator set of the underground building of the hydropower station was sorted out and analyzed.Through the analysis of the actual needs of the enterprise,the functional and non-functional design contents of the MR Simulation drill simulation platform were obtained,and the design strategy based on the general principles of MR Design and seven psychological design principles was developed.Then,seven basic design principles of design psychology are expounded,seven basic concepts guiding design in the simulation platform are analyzed,and the application scope and guiding significance of visibility,indication,signifier,constraint,mapping,feedback and conceptual model in the simulation platform of MR Simulation exercise are analyzed one by one.Finally,theoretical research is taken as the basis,through the design practice,testing and evaluation of the MR Simulation exercise simulation platform,the rationality and scientificity of the viewpoints of this paper are demonstrated,and the platform design is reflected and prospected,hoping to provide theoretical support and practical examples for the research and development of other special emergency plan exercise platforms.
