Embodiment Construction

[0033] figure 1 The illustration in FIG. 2 shows schematically, very strongly simplified, an elevator installation 10 of the type known per se, with an elevator car 12 , a rope 14 for moving the elevator car 12 and a connection between the ropes 14 . Counterweight 16 on the end opposite the elevator car 12. The sling 14 is guided on at least one pulley 18 . The pulley 18 or at least one of the pulleys 18 is driven by means of an electric motor acting as a drive 20 . At least one braking device 22 is provided for braking the elevator car 12 during operation of the elevator installation 10 .

[0034] The particular type of braking device 22 is not essential to the invention. The method proposed here is suitable for every type of braking device 22 as long as the braking device can be disengaged automatically. exist figure 1 In the view of , the braking device 22 is shown schematically and in simplified form, for example in the form known from GB 2 153 465 A. Accordingly, th...

Abstract

The invention is a method for controlling a braking device (22) of an elevator installation (10) as well as an elevator installation (10) having means (42, 44) for carrying out the method and a computer as an implementation of the method program, wherein said braking device (22) comprises at least one pressure element (24) capable of automatically disengaging for causing a braking action and for said pressure element (24) or each pressure element (24) to automatically A disengaged mechanism (32), wherein the lift installation (10) is determined by means of a model (42) of the elevator installation (10) with the corresponding travel direction (R), load state (m) and desired car deceleration (Vs) The respectively required braking torque (M) of the elevator car (12), wherein on the basis of said braking torque (M) is generated for controlling the automatic disengagement of the or each pressure element (24) acting as said pressure element (24) The control signal (40) of the device of the mechanism (32), wherein the actual car deceleration (Vi) is determined during the braking process of the elevator installation (10), and based on the determined The actual car deceleration (Vi) is calibrated, ie of the determined required braking torque (M) or of the control signal (40) generated based on the determined required braking torque (M).

Description

technical field [0001] The invention relates to a method for controlling a braking device of an elevator installation, an elevator installation having means for carrying out the method, and a computer program for carrying out the method. Background technique [0002] In this case, a basically known braking device of the elevator installation is actuated. The braking device comprises, for example, an electromagnetically liftable spring pressure brake and an electronically controllable electromagnet for lifting the spring pressure brake. The braking effect is achieved by means of the spring force of at least one spring. At least in the de-energized state of the electromagnet, the pressure element of the spring pressure brake with the brake lining rests against the abutment surface, for example the brake disk of the elevator installation, due to the spring force. The pressure element can be a pressure plate which can be pressed against a brake disc or it can be a pressure or ...
