Site construction safety management and control early warning device

The embodiment of the invention discloses an on-site construction safety management and control early warning device, which comprises an AI camera for acquiring an on-site image and storing the on-site image in a data storage module; the processor carries out image segmentation processing on the field image to obtain a first image of a construction area, carries out character recognition on the first image, determines a target area, carries out segmentation on the target area to obtain a plurality of sub-images, carries out numerical processing on the position and pixel point information of each sub-image, and obtains a plurality of sub-images; according to the processed information, based on a neural network algorithm, determining whether the person wearing in the sub-graph accords with a safety specification, and when the person wearing does not accord with the safety specification, sending a first control signal to an alarm module; the alarm module gives an alarm when receiving the first control signal.
