摘要： A position reference system for an elevator car includes a laser that emits a beam that is reflected from a mirror. Either the laser or the mirror is in a non-moving position, while the other is fixed to the elevator car and moves with it. The laser beam is modulated at two frequencies, one of which provides a coarse position of the elevator car while the other provides a fine position of the elevator car. Position calibration occurs when the elevator car is stationary. When the elevator car begins to move, the coarse position is tracked while the fine position is determined from the higher of the two modulation frequencies. The absolute position of the moving elevator car is thus always known to a degree of accuracy depending on the higher modulation frequency.

摘要： An apparatus and method for determining the speed of an elevator car. A radar speed sensor (30) is provided determining the velocity of an elevator car (2). The speed sensor produces a signal which is processed by a processor (52) and compared to a threshold speed value by speed detection module (70). The speed detection module produces an overspeed signal (72) triggering the operation of actuator (34) and safety brake (26).

摘要： A ropeless governor system is provided for governing the speed of an elevator car (2) in the event of an overspeed condition. An actuator for a safety device (30) is positioned in close proximity to an elevator rail (14) and activated to come into contact and provide a dragging force against the rail in the event of an overspeed condition. The ropeless governor is coupled to an elevator safety braking system (26, 28) such that the dragging force activates the safety brakes. A safety controller (91) is used to determine if the speed of the elevator car has exceeded a predetermined threshold level and to produce a triggering signal (96) to operate the ropeless governor.
