The invention discloses a method for eliminating hidden dangers of building engineering safety based on electronic beacon positioning and photographing, which comprises the following steps: A, establishing a data realizing one-to-one correspondence among constructors, electronic tags and photographing equipment. B. laying out readers and writers: dividing the construction site into regions. C. positioning hidden danger: after the construction personnel discover the hidden trouble, they send a photograph request to the main control computer, and the main control computer automatically identifies the hidden trouble position information and sends it to the photograph equipment. D, photographing and uploading: taking photograph and uploading hidden trouble photograph. E, system identification: the background system identifies the hidden trouble photograph information and sends it to the safety patrol inspector. G. Hidden danger rectification: the safety patrol inspector organizes thepersonnel to rectify the hidden danger, and uploads the rectification photos to match the hidden danger photos. The system can automatically identify the hidden trouble position in the hidden troublephotos, and any construction personnel can upload the hidden trouble photos on the construction site, so that the hidden trouble on the site can be discovered in a more timely and comprehensive manner, and the safety participation consciousness of the operation personnel can be effectively improved.
