The invention belongs to the technical field of safety design for escalators, and discloses a person crowdedness degree judging and distinguishing device. The device comprises a power supply, an emergency stop controller, a motor, a harness and infrared monitors, wherein the power supply, the emergency stop controller and the motor are arranged below an escalator, escalator steps are driven by the motor to move, first infrared monitors are symmetrically arranged on escalator exit boards, and second infrared monitors are symmetrically arranged on escalator handrail plates. According to the device, the emergency stop controller can judge the crowdedness degree of persons at an escalator exit according to conditions monitored by the first infrared monitors; when crowded or stampede accidents of the persons occur at the exit, the emergency stop controller controls the motor to stop running timely. The device is reasonable in design, simple in structure and applicable to optimization design of a loss reduction system for crowded or stampede accidents of the escalator.
