Abstract
The invention discloses a method for detecting missing-installation of stairs of an escalator. According to the method, an upper end station and a lower end station are each provided with two pulse sensors, and adjacent pulse signals are generated by the pulse sensors when the stairs pass; two pulse sensors are arranged at one side of a top chain wheel of the escalator and used for detecting rotating directions and rotating speeds; during the period of the adjacent pulse signals, the pulse signal counting maximum value of the two pulse sensors at one side of the top chain wheel of the escalator is a set value; in operation of the escalator, pulse signals of the two pulse sensors at one side of the top chain wheel of the escalator are counted during the period of the adjacent pulse signals, and when a counting value is larger than the set value, it is judged that upper stairs and lower stairs are missed or the two pulse sensors arranged on each of the upper end station and the lower end station have faults; and if the two pulse sensors at one side of the top chain wheel of the escalator have no level fluctuation during a certain period, it is judged that a fault happens, and pulse signal counting is reset after pulse signal counting of the two pulse sensors at one side of the top chain wheel of the escalator is completed. The method is not influenced by the escalator operation speed, stair missing-installation detection reliability and precision are improved and potential safety hazards of operation of the escalator are avoided.
