Definitions
- the invention relates to the conveyance of people in Elevator cars and in particular on one method and one System for the compensation of vibrations in elevator cars according to the definition of the claims.
- the object of the present invention is now a highly effective compensation of vibrations in systems for Encourage people to achieve such that the Vibrations are not noticed by the passengers.
- low-frequency vibrations so-called Interference vibrations that are considered by passengers to be special be perceived as disturbing, be compensated.
- the invention is supposed to use common techniques and procedures of load and Passenger transportation industry to be compatible. Also supposed to existing passenger conveyor systems with the invention can be easily retrofitted.
- the invention is based on a departure from that in the prior art Technology implemented vibration compensation Elevator cars.
- the basic idea of the invention is in vibrations and especially spurious vibrations, so Detect as early as possible in order to optimize them compensate. This is done by multiple entries from time course of vibrations. For one thing Vibrations recorded where they are perceived as disturbing become, i.e. at the elevator car and the other they will recorded where they are generated, i.e. at a Interference source.
- Disruptive acceleration values are, for example, by Deviations from the plumb line or ideal line of a Guide shoe caused along guide rails.
- Disturbing pressure values are, for example, pressure fluctuations in the Airflow around the elevator car. The is advantageous Accelerometer on a guide shoe or the Pressure sensor attached to the elevator car.
- the acceleration values of the elevator car are as Actual values and the acceleration or pressure values on the Interference sources are presented as disturbance variables at the input of a Control device laid.
- Control device for the temporal course of disturbance variables and the time course of actual values, i.e. the impact of Malfunction available on the elevator car.
- the temporal Course of actual values or of disturbance variables as a time function in preferably regular Periods recorded.
- As part of this Accuracy of detection will be the time from occurrence a disruptive force and its temporal development, both at the source of interference as well as at the elevator car.
- the relationship between these time functions is shown by described a transfer function. Disturbances and Actual values are recorded in the control device according to the Transfer function evaluated.
- the transfer function is based on mechanical parameters of the Passenger conveyor system such as the empty weight of the elevator car, the hardness of suspension / damping elements, the current Position and weight of a compensation mass, the current conveyor load, the current load distribution in the Elevator car, etc. At least one of these mechanical ones Parameter is known or is preferred regular periods of time are determined and updated thus updated known. Certain mechanical parameters like the empty weight of the elevator car, the weight of the Compensation mass, the hardness of suspension / Damping elements can be used once before commissioning of the passenger conveyor system. Other mechanical Parameters such as the position of the compensation mass, the Conveying load and the load distribution in the elevator car can be determined updated.
- disturbance variables become one Feedforward control and actual values for feedback control used.
- the transfer function thus allows one targeted activation of at least one Compensation mass taking into account the known or updates known mechanical parameters of the Pedestrian conveyor system.
- the interference is caused by a Compensatory force of the opposite sign and preferably neutralized the same amount.
- the Compensation force does not necessarily have to be the same amount Disruptive force, but it should be at least as large be that due to uncompensated interference components excited vibrations not perceived by the passengers become.
- the compensation mass is moved by at least one drive. The drive will controlled by the control device via manipulated variables.
- a Feedback regulation of the acceleration of the elevator car carried out.
- a controller function is provided in the control device. It receives as Acceleration setpoint is 0 because the acceleration on the elevator car for optimal driving comfort be as low as possible.

- low-frequency vibrations from 1 to 100 Hz, preferably from 2 to 20 Hz isolated by the control device.
- the low-frequency manipulated variables are targeted Compensating mass driven accordingly low frequency and eliminates interference vibrations.
- the procedure for compensation of vibrations in Elevator cabins are based on exemplary variants schematic action plans according to Figures 1 to 4 shown.
- the system for compensation of vibrations in Elevator cabs are in exemplary embodiments shown in Figures 6 to 8. Doing so Elevator car 5 by means of guide shoes 6 along Guide rails 7 out.
- the elevator car 5 is, for example. via suspension / damping elements 11 and one Catch frame 12 connected to the guide shoes 6.
- the Guide shoes 6 roll over guide rollers 6 'on the Guide rails 7.
- the suspension / damping elements 11 on the ground the elevator car 5 attached in the embodiment 7, the suspension / damping elements 11 are on Roof of the elevator car 5 attached.
- Interference sources 8 are e.g. uneven transitions from guide rails and Curvatures in the guide rails 7, causing vibrations, Centrifugal and inertial forces are generated in the elevator car 5 become.
- Interference sources 8 are, for example, via the guide rail 7 on the guide shoes 6 and from there into the elevator car 5 transferred.
- Other sources of interference 8 come from Pressure fluctuations in the air flow around the elevator car 5 forth and are transferred to the elevator car 5.
- Interference sources 8 are identified by means of at least one first sensor 1, 1 'recorded as disturbance variables Z.
- one first sensor 1 as an acceleration sensor 1 on one Guide shoe 6 attached.
- Acceleration values of the elevator cars are called actual values X recorded by at least one second sensor 2.
- a second sensor 2 as an acceleration sensor 2 on the elevator car 5, for example on the floor or on the roof of the Elevator car 5 attached.
- the effects of distracting Vibrations are therefore as close as possible to actual values X. recorded where they are perceived as disturbing, i.e. at the Elevator car 5, preferably close to the disturbing vibrations suspension / transmission to the elevator car 5 Damping elements 11.
- the time course of actual values X or of Disturbance variables Z are preferred as a time function regular periods of time recorded.
- As part of this Accuracy of detection will be the time from occurrence a disruptive force and its temporal development, both at the source of interference as well as on the elevator car 5.
- the Those skilled in the art can understand the present invention diverse variations in the detection and arrangement of Make at least one second sensor 2.
- a first one Acceleration sensor 2 is on the roof of the elevator car 5 mounted near the suspension / damping elements 11, one second acceleration sensor 2 is at the bottom of the Elevator car 5 at a distance from the suspension / Damping elements 11 mounted. This allows a spatial differentiated recording of the spread and compensation of disturbing vibrations from suspension / Damping elements 11 in the elevator car 5 by means of two Acceleration sensors 2.
- sensors 1, 1 ', 2 corresponds common industry standard, e.g. sensors 1, 1 ', 2 for example 200 measurements, preferably 20 measurements per second detected. All known sensors 1, 1 ', 2 can be used Sensor types of mechanical, optical and electrical design use.

For example. are natural to the designer and the fitter Suspension / damping characteristics known at a certain weight of the elevator car 5 from a certain Hardness of the suspension / damping elements 11 results. However, the weight of the elevator car 5 is often not exact known. This is particularly true when installing the Passenger conveyor system to where the elevator car, for example, often not yet fully equipped, e.g. not inside is lined, and thus its empty weight only with sufficient accuracy of, for example, 10% is known.
- the model building process is successful if between the input and output variables of the Control device 3 a relationship can be established to the Effect of incoming actual values X and disturbance variables Z targeted to compensate with outgoing manipulated variables Y. It is the mechanical parameter is the basis of the Transfer function. Depending on the input and The output variables of the control device 3 become a model of the Link created which is the actual one Emulates behavior.
