Construction Of University Laboratory Safety Evaluation System Based On BIM+BP

With the rapid development of China's education and scientific research level of colleges and universities continues to improve,the quality and quantity of laboratory equipment and facilities of university has been significantly improved,the special equipment in the science and engineering laboratory teaching and scientific research,national defense and other aspects of the project are widely used.The special equipment used in laboratory in the main gas tank,gas cylinders,pressure pipeline pressure,bearing type crane,crane,inside special motor vehicle,hydraulic jack,loading class 100 tons/thousand ton class large loading equipment etc..In the face of these large equipments,the laboratory has become one of the accident prone places,every year hundreds of accidents,accidents,often cause huge casualties and property losses,the threat of college students and the safety of life and property,resulting in some social problems.In 1970s,the technology of building information modeling(BIM)in the world within the scope of the construction industry has been rapid development,the beginning of this century BIM technology have been introduced to China and get the rapid development and application promotion,promote the great technology construction industry information integration reform.BP neural network has been a mature and new technology theory in the world,security,medicine and other fields.BP neural network mainly constructs safety evaluation system in building safety,and then combines relevant technology to evaluate building safety.In this paper the advanced BIM technology and BP neural network are applied to safety management,based on the basic principle of safety accident and evaluation system on the applicability of BIM technology.BP neural network is applied to safety evaluation,and then build a safety evaluation system model of high school laboratory BIM+BP.Many factors are related to the safety management in laboratory,this paper studies the key to solve the problem is:how to know the characteristics of the system safety management in laboratory and finally establish the structure transformation and decomposition model,construction safety evaluation system is scientific and effective,effective guidance in the actual application form to the management process.The research results of this project can improve the informationization level of university laboratory safety management,safety management and clear risk factors of university laboratory,reduce or avoid the occurrence of safety accidents,and provide theoretical and technical reference for the new safety evaluation system of university laboratory,has important theoretical significance and practical value.
