Rail transit full-scene intelligent construction management and control method and system based on resource constraint

The invention discloses a resource constraint-based rail transit full-scene intelligent construction management and control method and system. The method comprises the following steps of: acquiring construction time, a construction site and construction completion degree information of each construction based on a safety management key link through intelligent monitoring equipment on a rail construction site; carrying out analysis and data preprocessing on the collected data, and carrying out graphic visualization processing; a multi-target, multi-task and multi-resource construction operation scheduling model is constructed by using a key chain method, a buffer area is set by using a PCA method, urban rail transit operation construction management projects are reasonably scheduled, and full-scene management and control are performed for key links of construction management; and constructing a track construction cloud data warehouse, and displaying graphic visualization processing and full-scene management an
