Embodiment Construction

[0037] Before the exemplary embodiments of the invention are explained in more detail below on the basis of the figures, attention is paid to the fact that elements, objects and / or structures which are identical, functionally equivalent or have the same effect are provided with the same reference numerals in the various figures , and thus descriptions of these elements presented in different exemplary embodiments are interchangeable or applicable to each other.

[0038] figure 1 A schematic diagram of an elevator system 2 is shown. The elevator system comprises a car 4, a linear drive 6, a sensor 8, a signal generating unit 10 and a safety control unit 12. The car 4 is displaceably (or movable) received in an elevator shaft 14 (abbreviated: shaft). Such as figure 1 As shown, the car 4 is displaceable eg in the vertical direction. However, the invention is equally applicable to cars displaceable in other directions of movement, such as car 4 displaceable horizontally or dia...

Abstract

An elevator system comprising a car displaceably received in an elevator shaft and a linear drive embodied to drive the car. A sensor is arranged in the elevator shaft, and a signal generating unit is arranged on the car, said signal generating unit being embodied to generate a measurement signal in the sensor, which measurement signal depends on the (displacement) speed of the car in the elevator shaft. Furthermore, the elevator system has a safety control unit which is designed to detect the acceleration of the elevator car on the basis of the measurement signal and to bring the linear drive into a safe operating state if the detected acceleration exceeds a limit value.

Description

technical field [0001] The present invention relates to an elevator system having a signal generating unit arranged on a car of the elevator system and a sensor for detecting a signal of the signal generating unit arranged on an elevator shaft. Therefore, the speed or acceleration of the car can be ascertained reliably and quickly. Background technique [0002] Today, linear drives have emerged as an alternative to cable drives in elevator construction. Such a linear drive comprises a stator unit fixedly mounted in the elevator shaft and at least one rotor unit fixedly mounted on the car. The invention can be applied to an elevator system having a car and such a linear drive for driving the car. Elevator systems with linear motor drives are known, for example, in DE 10 2010 042 144 A1 or DE 10 2014 017 357 A1, wherein the primary part of the linear motor is provided by a suitably presented guide rail of the elevator system, and the secondary part of the linear motor Part ...
