摘要： A sensor system for controlling operation of an escalator arranged on a landing plate at the exit of the escalator includes a plurality of sensors arranged over a landing area of the landing plate. Each sensor is disposed at predetermined intervals with respect to the width direction along the width between two balustrades and the length direction along the moving direction of the escalator, and is configured to detect a predetermined pressure so as to obtain a transition of ON/OFF states in response to a load presence.

摘要： An elevator motion alert system is configured to alert a person of an object moving in at least one hoistway of an elevator system. The elevator motion alert system includes a sensor configured to detect object motion. A transmitter of the elevator motion alert system is carried by the object and is configured to transmit a pressure wave at a pre-defined frequency upon movement of the object. An electronic device of the elevator motion alert system is configured to receive and process the pressure wave for alerting the person of object movement.

摘要： A door switch inspection device for detecting an abnormal condition of a landing door switch used in an elevator is disclosed. Each of a plurality of landing door switches is disposed on a corresponding landing door at each landing floor for detecting an open/closed state of the landing door. The door switch inspection device includes a plurality of voltage detection units connected to the ground side of their respective landing door switches for detecting a voltage value of their respective landing door switches, and a switch contact monitoring unit for detecting an abnormal condition of a landing door switch, which is carried out by calculating a voltage difference between two adjacent floors and comparing the voltage difference with a threshold voltage.

摘要： An exemplary building sway operation system (10) for an elevator includes an acceleration sensor (11), and a data receiving unit (12) for receiving a sensor output from the acceleration sensor (11). The acceleration sensor (11) is designed to be mounted on a movable mass (6) of an active vibration control device (5) for a building, in order to detect the reciprocating motion of the movable mass (6) of the active vibration control device (5) responsive to the occurrence of earthquakes or strong winds.
