The invention belongs to the technical field of construction site inspection, and discloses an intelligent construction site on-site inspection management system and method based on a GPS technology.The intelligent construction site on-site inspection management system comprises: a video monitoring module, an image acquisition module, an engineering quality detection module, a central control module, a GPS positioning module, an inspection navigation module, an inspection module, an inspection management module, an inspection information statistics module, a construction data processing module, a safety alarm module, a wireless communication module, a data storage module, a terminal module and a display module. According to the invention, through the positioning module, a manager can visually know the current position and movement track of a person entering a construction site in real time; potential safety hazards can be effectively eliminated in the bud; the hidden danger rectification data and the construction safety data are input into a preset diagnosis model through a construction data processing module, safety production condition evaluation of a construction project is obtained, and the processing speed is increased; and an accident hidden danger is greatly reduced.
