| description | The invention discloses a light curtain sensor based escalator main driving chain monitoring method and system. The method comprises the steps of receiving a light receiving signal and a light shadingsignal generated by a light curtain sensor irradiating an escalator main driving chain; forming an image according to the light receiving signal and the light shading signal, and calculating the diameters of two adjacent pin shafts and the distance between the two pin shafts; and calculating the pitch and elongations of the two pin shafts; judging whether the elongations exceed the elongation range or not, and if yes, sending out an alarm signal. Through the light curtain sensor based escalator main driving chain monitoring method and system, the escalator main driving chain can be continuously monitored at high accuracy degree, the maintenance cost can be reduced, manpower resources can be saved, and hidden danger can be prevented.
