Abstract: In order to further enhance the work level and professional skills of fire supervision inspectors, improve the ability of units to implement the main responsibility of fire safety, and enrich and improve the learning methods of fire supervision and inspection work through information and digital means, this article constructs a three-dimensional digital system platform for fire supervision and inspection. The 3D digital system for fire supervision and inspection realizes the model construction of urban complex 3D scenes and automatic fire protection systems, simulation of fault states, training and assessment of supervision and inspection knowledge points, user and score management, and other functions. It can achieve three-dimensional roaming learning and immersive assessment for trainees. Introduced the system characteristics, composition framework, system functions, and application suggestions of the 3D digital system, and the system can greatly improve learning efficiency and effectiveness for trainees.

Key words: virtual simulation, fire supervision and inspection, automatic fire protection facilities, 3D digital system
