Abstract:  In order to actively promote the construction of first?class undergraduate education and cultivate high?quality fire engineering professionals, the construction status of virtual simulation experimental teaching system for construction engineering firefighting was analyzed by combining the core teaching content of fire engineering undergraduate talent training, and a set of virtual simulation experimental teaching system was constructed including fire protection system, fire fighting system, smoke extraction system, automatic alarm system and safety evacuation system of building engineering. The system contains introduction, design and assessment modules, in which the introduction module allows students to systematically understand the composition, operating principle and maintenance methods of building fire protection system, and the design module allows students to master the whole process of designing each system and deepen their mastery of the theory and methods of fire protection system in the assessment module. Compared with the traditional teaching methods, the virtual simulation teaching of building engineering fire protection can break through the teaching time and space limitation, improve the teaching efficiency, let students master the design methods of building engineering fire protection system more systematically, and improve the practical and innovative ability of students.

Key words:  first-class undergraduate education, building fire protection system, virtual simulation, experimental teaching
