The invention discloses an escalator health diagnosis system based on power edge calculation. The system comprises a motor power detection and calculation unit, a power change trend calculation unit and a logic judgment unit. The motor power detection and calculation unit is used for calculating the real-time active power Pmotor of a motor, The power change trend calculation unit is used for calculating the power change rate delta P/delta t of the active power Pmotor along with the time change. The logic judgment unit is used for judging whether to output a control signal for controlling the braking of the motor or not according to the active power Pmotor and the power change rate delta P/delta t. According to the system, the fault state of an escalator is detected through the power characteristic of the escalator, and personal injury caused after an escalator accident occurs is effectively reduced.
