Urbanization promoted the rapid development of Utility tunnel. However, there are some problems in the management of Utility tunnel currently such as management mean depends on manual, the complicated pipelines in Utility tunnel, the low efficiency of manual management and the high risk factor. The article puts forward a web-based Utility tunnel visualization information management system based on web to realize the lightweight visualization of building structure and building information, online prediction and model training of CO environmental data in web browser. Management system uses the secondary development of Revit to decouple the BIM model and loads the geometric model in the web page by WebGL. The background services puts the environment data which is collected by the terminal nodes to mysql database through the communication thread pool, and dynamically couple with the browser web page. Integrating Tensorflow.js to implement online training and prediction of CO based on LSTM in the browser. According to the test, management system works reliably and meets the design requirements.
