This paper studies and constructs an integrated business platform of intelligent utility tunnels that integrates monitoring,operation and maintenance, and operation. The platform is based on GIS+BIM, and combines the mainstream technologies such as the Internet of things, AI analysis, and micro service to achieve multi-dimensional visual monitoring, and standardized, processed and refined maintenance and operation of the utility tunnels. It provides reference for the establishment of project-level and even city-level utility tunnels’ monitoring, operation and maintenance platform.
