Research On Operation And Maintenance Management Module Of HVAC Equipment Based On BIM Technology

In recent years,BIM technology has become more and more mature in the direction of operation and maintenance management,and it has initially achieved results.BIM technology has proposed efficient solutions for operation and maintenance management.BIM technology has the characteristics of high information integration and strong visualization effects.Combined with the information management capabilities of database technology,the two coordinate the use of BIM technology-based HVAC equipment operation and maintenance management modules to comprehensively and carefully manage HVAC equipment.To ensure the sustainable operation of HVAC equipment.There is a large amount of work in the operation and maintenance management phase.Equipment maintenance is one of the key tasks in the maintenance phase.With the research target of HVAC equipment management,a BIM technology-based HVAC equipment operation and maintenance management module is established to improve the efficiency of HVAC equipment operation and maintenance.Through literature research,analyze the problems of the current traditional operation and maintenance management mode,and master the basic theory of equipment operation and maintenance management and computer database technology.In order to understand the inefficiency and unsustainability of the traditional operation and maintenance management mode,a HVAC equipment operation and maintenance management module based on BIM technology was developed.The modeling software Revit is used to build the model,and the operation and maintenance information is supplemented and optimized through the shared parameter method.Revit DBlink is used to transfer the information in the BIM model in the database and the BIM model in both directions to realize the preliminary application of BIM technology in the operation and maintenance management direction.Using the information in the BIM model,the HVAC equipment operation and maintenance management module developed in the database software Access,has realized efficient and precise management of the HVAC equipment operation and maintenance information.In order to solve the problem of slow running of traditional BIM models,a lightweight BIM model is created using a lightweight engine using Web GL technology.The BIM model is embedded into the Html webpage according to the Javascript language,and the BIM model of the browser and mobile device is visualized with the developed HVAC The equipment operation and maintenance management module is combined to realize the visualization of the operation and maintenance management of HVAC equipment.It has achieved the precise positioning of HVAC equipment and threedimensional roaming.It solves the problems of low informatization,large workload and low efficiency in the management of HVAC equipment.Based on the basic functions of the developed HVAC operation and maintenance management module of BIM technology,the specific case of a shopping mall in Shenyang is analyzed.The spatial visualization function of the developed HVAC equipment operation and maintenance management module based on BIM technology helps operation and maintenance managers to Efficient management of equipment basic information,equipment space location,and equipment operating status.In addition,the module’s report statistics function saves,updates,and accumulates the status of HVAC equipment.Combined with Revit DBlink,it can achieve sustainable management of HVAC equipment.The established lightweight model reduces the difficulty of management and improves the management efficiency.It helps operation and maintenance managers to quickly find the HVAC equipment that needs urgent maintenance,and realizes accurate visual management of HVAC equipment.Therefore,BIM technology and database platform play an important role in improving the operation and maintenance management level of HVAC equipment.The developed HVAC equipment operation and maintenance management module provides new management methods and means for HVAC equipment operation and maintenance management.
