The invention discloses a public safety monitoring system. The public safety monitoring system comprises a step detection module for detecting surface stress data and vibration amplitude of each step of an escalator; the laser scanning module obtains three-dimensional point cloud data of each step; the first processing module processes the three-dimensional point cloud data to obtain cascade crack data and a three-dimensional real-time model; the comparison module is used for establishing a three-dimensional coordinate system, and comparing coordinate points on the three-dimensional real-time model with coordinate points on the standard cascade model to obtain a cascade deformation volume; the prediction module inputs the surface stress data, the vibration amplitude, the step crack data and the step deformation volume of each step into a crack prediction model to obtain predicted crack data; the second processing module performs processing according to the predicted crack data and the crack threshold value data to obtain a crack risk degree, and generates a stop instruction when the crack risk degree is greater than a preset risk threshold value; the control module controls the escalator to stop running according to the stop instruction. The use safety of the stairs is improved.
