摘要： A position detecting device for detecting the position of an object (12) movable along a predetermined path of movement, comprising a signal transmission medium (13) extending along the path of movement, a signal generator (15) movable together with said movable object (12), by means of which a signal can be coupled into the signal transmission medium (13), at least one signal receiver (29, 33) at an extraction location in an end portion of said path of movement, a signal propagation time measuring means (35, 37) adapted to determine the signal propagation time between coupling location and extraction location (45), wherein the signal generator (15) is designed to deliver a periodically repeating signal pulse sequence (Fig. 2) in which the time intervals between consecutive signal pulses are different for each pair of consecutive signal pulses each, the period duration of the repetitive signal pulse sequence is greater than the maximum signal propagation time with maximum interval between coupling location and extraction location, and the time intervals between consecutive signal pulses are shorter than the maximum signal propagation time.

摘要： In accordance with a preferred embodiment of the present invention, an electronic safety system for elevators for preventing unsafe elevator operation has a central controller which monitors a variety of sensors, contacts, and switches over an electronic safety bus. A plurality of bus nodes are distributed throughout the elevator system and are in constant communication with the central controller over the safety bus. The bus nodes interface with sensors, switches, contacts, detectors, components, and other safety equipment of the elevator system at each location and provide status information back to the controller. The controller comprises a microprocessor board with an input/output port in communication with the safety bus and bus nodes. Upon sensing an unsafe condition, the controller sends control signals to an elevator control system and a drive and brake system to arrest the elevator car in a safe manner.
