[Objective]In this study,we aim to use digital twin technology to develop an intelligent digital twin laboratory safety management platform.This platform’s foundation framework includes physical,technology,data,application,and interaction layers.By establishing virtual twins of laboratory safety-related physical entities and hardware systems,we can leverage laboratory safety big data to conduct comprehensive virtual simulation safety management.This approach can effectively address challenges such as the life cycle management of hazardous chemicals,electric circuit and high-power electrical appliance warning,gas cylinder monitoring,safety digital assets,and data statistics.The goal is to promote the digital transformation of university laboratories and pioneer a replicable and scalable development model.Digital twin technology can open a new ecology of university laboratory safety management.[Method]Yangzhou University’s digital twin laboratory safety management platform has conducted three-dimensional modeling of the buildings and surrounding environments of medium-and high-risk laboratories across the university.With the construction of intelligent hardware and software platforms,the digital twin development of dangerous chemicals,high-temperature equipment,high-power equipment,special equipment,laboratory waste,and other dangerous sources has been conducted.To build a digital twin laboratory security management platform,the above functions are implemented in addition to the hardware(e.g.,infrared thermal imaging camera,intelligent power module,dedicated server,intelligent access control,electronic class plate,and gateway),which mainly includes three software systems:laboratory basic data management system,hazard monitoring management subsystem,and laboratory visual management platform.After more than two years of practice,we have summarized our experiences and future development plans as follows.First,we have been constantly accessing and iterating more advanced hardware equipment.Second,hardware and software are combined to achieve intelligent management.Third,several systems are created to unify visual application entries.Fourth,the platform can be further expanded to include,but not limited to,the use of artificial intelligence(AI)technology to determine the illegal operation of the experimental personnel in the monitoring screen,such as not wearing a lab coat,not wearing protective equipment,reagent cabinet door unclosed,high-temperature equipment unattended,and WeChat notification to the individual.The laboratory monitoring is connected to the mobile phone terminal of the corresponding teacher and security officer with permission,and the laboratory security situation can be viewed in real time.The intrusion equipment in the electrical circuit,such as small sun heaters,hot kettles,and curling irons,can be detected,and nonintrusive equipment,such as ovens,autoclave sterilizers,refrigerators,incubators,and water baths,can be accurately identified.The management department can initiate safety education and drills based on real scenes and data for laboratories with potential safety risks.Digital twins,AI,big data,cloud platforms,and other technologies can be used to conduct multidimensional analyses of digital assets and security data and provide scientific decisions to laboratory security management departments.[Conclusions]Through research on the construction of a university laboratory security management platform using digital twin technology,a physical model,cloud sensor,system database,and other technologies inside and outside the laboratory are fully utilized to complete mapping,data collection,and analysis in the virtual space.Moreover,a new laboratory security management mode that combines virtual and real space is developed,which provides a reference for constructing and developing university laboratory security digital transformation.
