Abstract (en)
Safety device and method for preventing accidents in the combplate area of escalators or moving walkways. The safety device comprises: - at least one capacitor (8), each one formed by a first capacitor plate in contact with a combplate (2) or floor plate of an escalator or moving walkway (1) and a second capacitor plate (9) connected to a reference voltage; - a capacitance measuring module (7) for measuring the capacitance (C) of the at least one capacitor (8), obtaining at least one capacitance signal (20); - a controller (6) configured for comparing each capacitance signal (20) with at least one predefined value (22) and, based on said comparison, deciding whether a dangerous situation has occurred, and in that case sending the escalator or moving walkway (1) a warning signal or a stop order signal. This safety device can detect when human skin is close to the combplate area to stop the escalator or moving walkway, and thus avoiding human body injuries.
