Embodiment Construction

[0019] figure 1 An elevator shaft 1 is shown in which an elevator car 2 is accommodated, the vertical position of which is changed by a drive 3 . In order to determine the vertical position of the elevator car 2 in the elevator shaft 1 , a first pressure sensor 4 is now arranged, for example, on the ceiling of the elevator shaft, and a second pressure sensor 5 is arranged in the elevator car. The pressure measurement values ​​of the pressure sensors 4 , 5 are subtracted by an evaluation unit, which is not shown in the figure. Via the pressure difference, the distance can be determined from the air pressure relationship of the air pressure difference between the vertical position of the first pressure sensor 4 and the vertical position of the pressure sensor 5 arranged in the elevator car 2 . The pressure sensor is usually designed as a CMOS component and has a resolution of up to 8 cm in vertical position determination. exist figure 1 In the shown embodiment, a binary posit...

Abstract

The invention relates to a device and a method for the determination of the vertical distance of objects during the execution of positioning tasks with a vertical portion of travel. The problem addressed, of providing a device and a method for the determination of the vertical distance of objects during the execution of positioning tasks with a vertical portion of travel that can effect a vertical distance determination, or with which a vertical distance determination can be effected simply with a minimal use of equipment even after a power failure, is solved by a device for the determination of vertical distance in such a way that at least one first pressure sensor (4) is arranged on a first object (1), and at least one second pressure sensor (5) is arranged on a second object (2), with the objects (1, 2) changing their relative position to each other during the execution of the positioning. Analyzing means are provided, by means of which the vertical portion of the travel between the positions of the objects (1, 2) can be determined from the difference of the measured pressure values of the first and the second pressure sensors (4, 5).

Description

technical field [0001] The invention relates to a device and a method for determining the vertical distance of an object during the execution of a positioning task with a vertical displacement component. Background technique [0002] A typical positioning task with a vertical displacement component is, for example, the positioning of an elevator car in an elevator shaft. Elevators generally need to be positioned to within an accuracy of almost a millimeter so as not to create any entry corners or steps at the transitions to the floors of the respective floors. The control device of the elevator particularly needs to recognize which floor the elevator is located on, so as to control the elevator according to the control instruction of the elevator user. Different systems have been used to date to determine the position. It is therefore known to use binary position sensors at each floor which simply signal the elevator that it has reached a floor and can start its decelerati...
