  • Patent number: 10392230
    Abstract: The present invention discloses an integrated test system and method for an escalator, the escalator comprises a control cabinet and a motor. The test system comprises a driver connected in series between the control cabinet and the motor for driving the escalator to simulate overspeed or unintentional reversal faults, a sensor mounted on a step or escalator handrail belt of the escalator for obtaining quantitative speed signals, and an operation device connected to the driver and the sensor for controlling the driver for different detection items and processing and displaying the speed signals. With the test system and method described herein, the defects of non-universal, unintuitive and non-quantitative nature, and low accuracy in the existing art are overcome. The test system of the invention is capable of discovering a lot of hidden dangers of accidents and even system risks which are difficult to be found by the existing art.
