The invention provides an escalator handrail belt and step speed deviation detector based on an AT89C51 single chip microcomputer. The detector comprises a base, a vertical rod, an overturning arm rod, a rotating arm rod, an ultrasonic range finder and a target block. The vertical rod is vertically arranged on the base and can rotate, a first notch is formed in the end of the vertical rod, one end of the overturning arm rod is arranged in the first notch of the vertical rod in a hinged mode, and the overturning arm rod can overturn up and down on the vertical rod; one end of the rotating arm rod is rotatably arranged at the other end of the overturning arm rod, a second notch is formed in the other end of the rotating arm rod, and the ultrasonic range finder is arranged in the second notch of the rotating arm rod in a hinged mode; the target block is positioned on the escalator handrail belt; the ultrasonic range finder comprises an AT89C51 single-chip microcomputer, a reset module, a step speed setting module, an ultrasonic ranging module and a display module. Real-time control and non-contact measurement can be achieved, and the detection precision is improved.
