Definitions
- the invention relates to a method for controlling a braking device of an elevator installation, an elevator installation with means for carrying out the method and a computer program for implementing the method.
- a basically known braking device of an elevator system is activated.
- the braking device comprises, for example, an electromagnetically releasable spring pressure brake and an electronically controllable solenoid for releasing 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 due to the spring force is a brake pad exhibiting a pressure element of the spring pressure brake on a counter surface, for example on a brake disc of the elevator drive.
- the pressure element may be a pressure plate which can be pressed against the brake disc or it may be a pressure or brake shoe which can be pressed, for example, to a brake drum.
- Such or comparable braking device of an elevator installation is intended to hold an elevator car of the elevator installation in a holding position. In a lift installation comprising several elevator cars, this has its own braking device for each elevator car.
- the following description is continued in the interest of better readability, but without abandoning a broader generality, the example of an elevator system with exactly one in exactly one elevator shaft moving elevator car. An elevator system with several elevator cars in a shaft or in several shafts is always read along.
- a braking device In addition to holding the elevator car in a holding position, a braking device is necessary and designed to be able to decelerate the elevator car during operation at any time, so especially in case of an error situation safely. Possible error situations are, for example, an unexpected opening of a car door, an excessively high driving speed, a loss of a stop position and so on.
- the braking device When the braking device is activated, it is often provided that the activation takes place in such a way that a maximum braking effect results. This leads to a strong and unpleasant for passengers in the elevator car delay. To avoid this, systems are known which regulate or control a respective effective braking torque.
- a braking device in which a control of a plurality of electromagnets takes place in each case by means of a pulse-width-modulated drive signal.
- a load and direction-dependent control of a braking device is known.
- EP 1 870 369 A contains explanations for the determination of mass parameters of an elevator installation.
- An object of the invention is to provide a braking device of the type mentioned above, which causes over a long time of operation of the elevator installation and the braking device comprising an efficient dosing of a respective applied braking torque, such that on the one hand reaches a necessary delay of the elevator car On the other hand, passengers in the elevator car will not find the forces acting on deceleration disturbing.
- the braking device comprises at least one intended for effecting the intended braking effect, automatically detachable from a counter surface (airable) pressure element with a brake lining, in particular at least one electromagnetically releasable spring pressure brake with such a pressure element. Furthermore, the braking device comprises means for automatically releasing the or each pressure element from the mating surface, for example at least one electronically controllable electromagnet.
- a model of the elevator installation taking into account a respective operating state of the elevator installation, such as a respective direction of travel of an elevator car to be braked, an automatically determined respective state of charge of the elevator car and a predetermined or predefinable desired cabin delay a braking torque necessary for braking the elevator car is determined.
- the model of the elevator installation includes a reduced to the location of the braking device mass of moving elevator parts, such as elevator car, allowable payload, counterweight, inertial masses of idler rollers and drives, rope masses taking into account Umh Kunststoffungs perceptionen, translations and roller and drive diameters. Furthermore, the model of the elevator system includes an experience according to friction portion counteracts a movement of the elevator parts.
- the model of the elevator installation is sufficiently precisely described solely by specifying a weight ratio of the permissible load to the cabin weight and a degree of balance.
- the degree of balance determines the proportion of payload in the elevator car required to establish a mass balance between the counterweight side and the cabin side.
- a degree of balance of 50% determines, for example, that when the elevator car is loaded with half of the permissible load, the mass balance is established.
- the necessary braking torque is not to be understood as an absolute value specification, but the necessary braking torque may be a braking relationship.
- the required drive signal can be read from the brake characteristic.
- the automatically releasable pressure element or a plurality of such pressure elements is referred to below together with the mating surface according to the usual language for a short time as a brake. If the device for releasing the brake is not actuated at all, the maximum braking effect results. If the device for releasing the brake is activated to the maximum, the brake is completely released and there is no braking effect. A control of the device for releasing the brake between these extremes allows a dosage of the braking effect.
- the control signal generated on the basis of the determined braking torque basically causes the metering of the braking effect in accordance with the determined braking torque.
- the braking characteristic of the braking device is calibrated, namely a calibration of the determined necessary braking torque and / or a calibration of the triggering signal generated on the basis of the determined necessary braking torque.
- the control signal used for controlling the means for releasing the brake or a corresponding control variable for controlling the electromagnetically releasable spring-pressure brake is in a physically defined relationship to the resulting pressure force of the pressure element against the counter surface and thus taking into account a corresponding Bremsreibyess to the braking torque.
- This physically defined relationship determines the course of the braking action between the extremes, thus allowing a dosage of the braking effect.
- This physically defined relationship is based on the braking characteristics.
- the braking device or the braking characteristic of the brake device is calibrated. The physically defined relationship or the braking characteristic is thus recalibrated based on the actual cabin deceleration. If the actual cabin deceleration corresponds exactly to the desired cabin deceleration, the braking characteristic undergoes no change.
- the braking characteristic represents the expected braking torque as a function of the triggering signal.
- the expected braking torque of an electromagnetically releasable spring-applied brake results from a spring force value and a magnetic force value.
- the spring force value includes the spring force caused by a spring and the magnetic force value takes into account the counterforce caused by the electromagnet.
- the counterforce caused by the electromagnet is typically in a quadratic dependence on a coil current of the electromagnet and the drive signal usually directly determines the coil current.
- the spring force value and the magnetic force value respective friction values, lever systems and possibly other factors, such as a gap or a summation of several braking surfaces are taken into account.
- the calibration of the braking device or the braking characteristic of the braking device thus includes a correction of the spring force value and the magnetic force value.
- the brake characteristic recalibrated by means of the corrected spring force value and the corrected magnetic force value thus reflects an actual braking behavior.
- the advantage of the approach proposed here is that a predetermined or predefinable desired cabin deceleration flows into the method for controlling the braking device.
- the desired cabin delay is chosen so that on the one hand a necessary delay the elevator car results and on the other hand passengers in the elevator car do not feel the forces acting on deceleration disturbing. Compliance with these two boundary conditions is referred to below as efficient braking torque dosage.
- the advantage of the approach proposed here is that such an efficient dosing of a respectively applied braking torque during a long time of operation of the respective elevator installation is possible, theoretically during the entire operating life of the elevator installation.
- transient effects can be induced in the overall system of the elevator installation or in the braking device, such as temperature or humidity differences and concomitant effects on the braking process as well as material wear in the elevator installation and take into account associated changing movement resistance and the like, so that regardless of such effects, a consistent over a long period of operation braking effect is achieved.
- Such a calibration is performed such that, for example, when compared to the desired cabin delay only half the actual cabin deceleration calibration is performed, which in a next braking operation to a doubling of the determined necessary braking torque or a corresponding adjustment of the Anêtsignais, for example an adjustment a pulse width modulated drive signal leads.
- the continuous calibration during operation of the elevator system causes the same braking effect over a long period of operation, ie at least a period of several months or at least during a usual service interval. Due to the efficient dosing of the respective applied braking torque while the elevator system as a whole, the passengers traveling along and the braking device and the preserving the braking effect coming into contact materials are spared.
- the calibrated brake characteristic is evaluated with respect to tolerable limit characteristics.
- the calibrated braking characteristic is released for further use, as long as the calibrated braking characteristic within the limited by the boundary characteristics.
- Calibration is automatic.
- the marginal characteristics indirectly determine the extent to which deviations between the actual cabin deceleration and the desired cabin deceleration are considered to be comparatively small and basically tolerable deviations. If, in the case of such a small deviation, the calibration takes place automatically, ie without the intervention of operating or service personnel, a continuous automatic adaptation of the braking device to possible transient effects results.
- a warning message is issued as soon as the calibrated brake characteristic leaves the limits determined by the limit characteristics.
- the warning message can be output in the form of an optical and / or acoustic warning message and / or an electronic message by automatic activation of at least one corresponding actuator.
- the warning message may additionally or alternatively also be output in such a way that the elevator installation is automatically switched to an assigned, predefined or predefinable operating mode.
- a pulse-width-modulated drive signal is generated as the drive signal on the basis of the calibrated necessary brake torque.
- a pulse width modulated drive signal has the advantage that in a circuit implementation of a pulse width modulator by means of electronic switching elements, in particular bipolar or MOS transistors or IGBTs, they can operate in a low-loss switching operation.
- a predetermined or predeterminable number of braking operations and one calibration each are performed. Multiple braking operations allow better calibration of the braking device, with each new calibration during the initialization phase, the calibration in each case the actual cabin delay increasingly better with the desired cabin delay in line brings.
- an expected braking time is calculated in each case on the basis of the desired cabin deceleration and that, after the expected braking time has elapsed, the drive signal is predetermined in such a way that the braking device generates a maximum braking torque.
- the elevator system is kept safe and energy-saving at a standstill.
- the braking device shown at the beginning this means that the device for releasing the brake is not activated at all, that is to say the activation signal is set to zero. This results in the maximum braking effect. At the same time this means that the electronically controlled electromagnet is de-energized.
- the innovation proposed here is also an elevator system with at least one elevator car and a braking device intended for braking the elevator car and means for carrying out the method as described here and below.
- the means for carrying out the method preferably comprise at least the model of the elevator installation and an elevator control.
- An implementation of the method is advantageously considered in the form of software or a combination of software and hardware.
- the innovation is also a computer program which functions as a control program for the elevator installation and comprises program code means for carrying out all steps of the method described here and below when the control program is executed by means of an elevator control of the respective elevator installation.
- the elevator control comprises a memory in which the control program is loaded, and a processing unit in the form of or in the manner of a microprocessor, by means of which the control program can be executed.
- the method or the method is executed in an optional embodiment by execution of the control program.

- the actual cabin delay Vi In order to determine the actual cabin delay Vi, only a trusted worthwhile area. If unexpected changes are detected during the braking process, the measurement may not continue to be used. Unexpected changes may be caused, for example, by an error or discontinuity in a guidance system. If the actual cabin delay Vi is determined in such a way, an actual braking torque MM is calculated on the basis of this actual cabin delay Vi and using the model 42. This actual braking torque M M thus determines an operating point or a test point of a braking characteristic. On the basis of this working or test point, the braking characteristic stored in the brake device model 46 is calibrated or recalibrated in a calibrator 50. Such a calibration procedure is explained in more detail in connection with FIG.

- the braking torque M is not an absolute value specification, but with regard to the braking torque M, it is a magnitude indication in relation to the effective braking torque and, with respect to the drive signal 40, an indication of the magnitude in relation to the coil current.
- the theoretical relationship between the activation signal 40 and the resulting braking torque M can be represented by a parametric function. An intersection of the graph Kl with the zero line of the braking torque M results in the so-called closing point PI of the brake device 22. If the control signal 40 exceeds this closing point PI, the electromagnet lifts the pressure element 24 away from the opposing surface and a resulting braking torque M is eliminated or becomes zero.
- the brake device 22 is located in the control range, where a braking torque M corresponding to the drive signal 40 is established.
- the electromagnet is switched off. This results in the intersection of the graph Kl with the zero line of the drive signal 40. This intersection can be referred to as the operating point P2 of the brake device 22.
- the spring force of the spring 30 determines the braking torque M.
- the braking characteristic or the theoretical relationship between the activation signal 40 and the resulting braking torque M, represented by the graph K1 can therefore be represented as follows:
- Braking torque M spring force value FF - (magnetic force value FM x square of the activation signal 40)
- the spring force value FF is a braking torque component caused by the spring force of the spring 30,
- the magnetic force value FM is a braking torque component which can be effected by the electromagnet depending on the control signal 40, and
- the Anêtsignais 40 is a coil current / corresponding signal.
- the tolerance range is in the figure 5 through
- the tolerance graphs ⁇ 2 ', K2 "define the limit values G or the tolerable limit characteristics ⁇ 2', K2" when the braking device 22 is activated with a drive signal 40, which is defined based on the theoretical relationship K1. This results in a specific actual braking effect and a resulting actual cabin deceleration Vi, from which the actual braking torque can be calculated by means of the model 42 of the elevator installation 10.
- the calibrated braking characteristic K3 can be described here using, for example, a mathematical standard method for the A as described in the least squares method are calculated.
- the calibrated braking characteristic K3, which runs as close as possible to the data points is searched using data points predetermined by the theoretical relationship, represented by the graph K1, and the further acquired test points T1, T2, Tn.
