Abstract: A door operation controller for an elevator includes at least one sensor arranged in a doorway at a landing for detecting moving direction and/or moving speed of a person or an object in or near the doorway during a time period from when the elevator door is opened until when the elevator door is closed at the landing. The controller is configured to control door operation in response to the detection of a person's or object's movement in or near the doorway at the landing.

Abstract: 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.

Abstract: A monitoring system for a passenger conveyor is provided. The passenger conveyor includes a motor for driving the passenger conveyor and an inverter for supplying current to the motor. The monitoring system includes a current sensor for detecting the current supplied to the motor; a temperature sensor for detecting the temperature of the motor; a data collecting device for receiving detected data from the current sensor and the temperature sensor; and a controller connected to the data collecting device. The controller is configured to calculate an idle operation motor torque during an idle operation of the passenger conveyor based on current and temperature detected during the idle operation; and determine that a fault exists in the passenger conveyor when a difference between the idle operation motor torque and a reference motor torque exceeds a predetermined threshold.
