the emergency device is used for implementing emergency measures to prompt staff to stop the construction step if the risk level exceeds a preset value;
and the reminding device is used for monitoring the position of the staff end in real time, judging whether the position is in the safety area or not, and further reminding the staff end if the position is not in the safety area within the preset time.
9. A construction quality safety risk management device, comprising:
the simulation module is used for acquiring a construction drawing and carrying out simulation on a construction scheme according to the construction drawing;
the monitoring module monitors the construction process of a target building in real time and acquires a video of the construction process;
the comparison module is used for comparing the video with the simulation training result;
the judging module is used for identifying the inconsistent construction steps and judging the risk level of the construction steps if the construction steps are inconsistent;
the emergency module is used for implementing emergency measures to prompt staff to stop the construction step if the risk level exceeds a preset value;
and the reminding module is used for monitoring the position of the staff end in real time, judging whether the position is in the safety area or not, and further reminding the staff end if the position is not in the safety area within the preset time.
10. A computer-readable storage medium, in which a computer program is stored which can be loaded by a processor and which executes the method of any one of claims 1 to 7.
