- EP 1 232 988 A1 describes a method and a system for determining the position of an elevator car of an elevator system arranged movably in an elevator shaft according to the preamble of claim 15.
- EP 1 232 988 A1 describes a method and a system for determining the
- an image capture unit arranged on the elevator car captures image data of a guide rail in the elevator shaft, which is considered as shaft equipment, and transmits this to a computing unit.
- the computing unit extracts a one-dimensional image in the form of an image in the direction of travel from the image data of the image acquisition unit
- Elevator car oriented image vector This current picture is shown with a
- each stored image in the form of a one-dimensional comparison image vector oriented in the direction of travel compared in the direction of travel, each stored image being assigned a position of the elevator car in the elevator shaft.
- the position of the elevator car in the direction of travel can be determined from the comparison of the two image vectors
- Elevator shaft can be determined.
- the determination of the position of the elevator car is based on the knowledge of the position at a previous point in time. If this previous position is not known, for example after restarting the system or the entire elevator system, the
- Determination of the position of the elevator car can be determined independently of the previous position of the elevator car. To do this, the current image is compared with all the saved images and the saved image with the largest one is determined
- this object is achieved with a method with the features of claim 1 and a system with the features of claim 15.
- images of other shaft components or shaft equipment serving other functions are recorded with an image capture unit arranged on the elevator car.
- a currently recorded image is compared with at least one stored comparison image of the shaft components or shaft equipment mentioned in a direction of travel
- Elevator car compared to determine a current position of the elevator car in the direction of travel.
- the method has a start phase, a check phase and a decision phase, with at least one method step being carried out in each phase.
- the review phase and the decision phase can be carried out several times in succession.
- the inspection comparison characteristic value indicating a measure for a match of the inspection image and with the comparison image of the inspection acceptance position.
- the check acceptance position is determined as the current position of the elevator car
- the check acceptance position is excluded as the current position of the elevator car.
- the position of the elevator car is not determined by a one-time comparison of a current image with all comparison images, but a position recognized as a possible position, a so-called start-acceptance position, is checked at least once, possibly several times, before one the so-called check acceptance position resulting from the start acceptance position is determined as the actual position of the elevator car.
- the position of the elevator car can thus be determined very reliably and thus reliably. Since the exact knowledge of the position of the elevator car in the
- safe operation of the elevator system can also be ensured after a restart of the system for determining the position of the elevator car or the entire elevator system.
- the method according to the invention is only carried out if there is no information about the position of the elevator car in the elevator shaft. It becomes one so-called initialization operation carried out.
- the system switches to normal operation, in which the position is determined based on the knowledge of the position at a previous determination time.
- the position can be determined, for example, using the method according to EP 1 232 988 A1 or a method according to the not previously published international patent application by the applicant with the
- the method is carried out in particular by a computing unit which, in particular, is arranged on the elevator car like the image capturing unit and with a
- Elevator control of the elevator system is in communication connection.
- the elevator shaft of an elevator system is usually aligned in the vertical direction, so that the direction of travel of the elevator car in the elevator shaft runs in the vertical direction apart from small deviations.
- a direction transverse to the direction of travel of the elevator car runs in the horizontal direction.
- the position mentioned in the direction of travel of the elevator car can thus be understood to mean the vertical position of the elevator car or the height of the elevator car in the elevator shaft.
- the direction of travel is also referred to below as the z direction and the direction transverse to the direction of travel as the x direction.
- the position of the elevator car in the direction of travel is determined by the elevator control system
- Elevator system needed to keep the elevator car safe and accurate within the
- the speed and possibly also the acceleration of the elevator car can be determined. These variables are also used in particular by the elevator control system.
- the speed and / or the acceleration of the elevator car can be determined in particular by the computing unit mentioned, but also by the elevator control.
- the elevator car is in particular with a suspension element in the form of a rope or a Bands connected to a prime mover.
- the drive machine can thus move the elevator car in the elevator shaft.
- the elevator car can also have a drive arranged on the elevator car, for example in the form of a friction wheel drive or a linear motor, and thus independently of a suspension element in the
- the image capturing unit in particular captures images that are made up of individual pixels. It is in particular designed as a digital camera, for example in the form of a so-called CCD or CMOS camera. For example, the camera has one
- Image acquisition unit can also be designed as another image acquisition system that can record and display a surface structure. It can also be used, for example, as an infrared camera, scanner, X-ray recording device,
- Ultrasound imaging system can be executed. It would also be sufficient if the
- Image acquisition unit would only capture one column.
- Each of the pixels mentioned is assigned a so-called pixel value by the image acquisition unit, which in particular represents a measure of the brightness value of the surface section of the recorded object assigned to this pixel.
- the pixel value can, for example, be coded with 8 bits, that is to assume a total of 256 different values.
- the image capture unit is in particular arranged such that the columns in the direction of travel (z direction) of the elevator car and the lines transverse to the direction of travel (x-
- the image capture unit is arranged on the elevator car in such a way that it serves images of other functions
- Shaft components or shaft equipment can accommodate.
- “Shaft components” are to be understood here to mean parts of the elevator shaft that are available for other purposes, for example shaft walls.
- “Shaft equipment” is to be understood here to mean parts which are mounted in the elevator shaft when the elevator system is being assembled, that is to say, for example, guide rails for guiding the elevator car.
- the shaft components and shaft equipment mentioned are not primarily installed or assembled in order to determine the position of the elevator car enable, but serve another purpose, for example in a shaft wall, to form the elevator shaft or in a guide rail, the
- the one or more stored comparison images, with which a currently recorded image is compared, are also recorded by the image acquisition unit in a so-called Lemfahrt and then stored in a memory by the computing unit.
- the comparison images can in particular overlap in the direction of travel or can also overlap twice. In particular, they overlap in such a way that two comparative images after next to one another touch each other.
- the currently recorded image can be post-processed.
- start image that is, a current image when the elevator car is at a standstill
- This start image is compared with all stored comparison images, each comparison image being assigned to a specific position. In this comparison, the for each possible position of the elevator car, ie over an entire possible travel range
- Elevator cabin a so-called start comparison path determined.
- Adjacent possible positions are shifted from each other, for example, by a distance that correspond to a pixel in the current image or a comparison image.
- the start comparison path is a measure of a match of the start image with the comparison image of the respective position.
- the current image is compared pixel by pixel with the respective comparison image, that is to say the pixel values of two pixels lying one above the other.
- the comparison image consisting of a section of a previously recorded image is pixel-wise in
- Direction of travel (z direction) shifted from the current image and a comparison of the comparison image and the selected section of the current image is carried out.
- the selected section of the current image is also referred to below as the image lying below the comparison image or the image below.
- Each position of the comparison image relative to the current image corresponds to a position of the elevator car in the elevator shaft. The position of the elevator car thus results from the information from which location in the elevator shaft the comparison image comes from and the position of the comparison image in the current image. The position that is assigned to a comparison image thus also results from these two pieces of information.
- the squares are the difference in the pixel values of the superimposed pixels of the comparison image and
- the result of the global linear cross correlation mentioned above is normalized. For this purpose, the root of the sum of the squares of the pixel values of the comparison image and the root of the sum of the squares of the pixel values of the image below are calculated. To calculate the normalized cross-correlation, the result of the above-mentioned global linear cross-correlation is divided by the product of the two roots mentioned.
- start evaluation criterion can consist, for example, in that the start comparison parameter of a start acceptance position depends on The type of the start comparison characteristic value must be greater or smaller than a first threshold value. If the start comparison characteristic value has been determined on the basis of a normalized cross-correlation, then it must be greater than the first threshold value in order to meet the start evaluation criterion. This is assumed in the following. It can happen that one or more start acceptance positions
- Fulfill selection criteria In the case of several start acceptance positions, the following method steps are carried out accordingly for each start acceptance position.
- the elevator car is moved by an inspection travel path to a inspection position, a travel direction and the length of the inspection travel path being known.
- the direction of travel and the length of the checking travel can be determined, for example, by the elevator control from the control of the drive machine. It is also possible that a shift of the check image with respect to the start image is determined and the direction of travel and the length of the check travel path are determined therefrom. This type of positioning is referred to below as relative
- the verification travel distance is, for example, between 2 and 10 cm.
- a check acceptance position is determined on the basis of the previous acceptance position and the checking travel path. If the checking phase is carried out after the start phase, that is to say for the first time after the start of the method, the aforementioned previous acceptance position corresponds to the start acceptance position. If the verification phase is carried out after a decision phase, that is to say once again after the start of the method, the aforementioned previous acceptance position corresponds to the
- the check acceptance position corresponds to the position where the elevator car should be if the start acceptance position or the
- Verification acceptance position of the previous verification phase would have corresponded to the actual position of the elevator car.
- a check picture ie a current picture
- a check comparison characteristic value is then determined for the check acceptance position of the elevator car, the check comparison characteristic value indicating a measure for a match of the check image and with the comparison picture of the check acceptance position.
- the verification image is therefore compared with the comparison image of the verification acceptance position. This quasi checks whether the check acceptance position corresponds to the check position, that is to say the actual position of the elevator car.
- the check comparison characteristic value is determined in particular in the same way as the start comparison characteristic values in the start phase. However, it is also possible for another method to be used to determine the verification comparison characteristic.
- the verification comparison characteristic value is determined in particular only for the verification acceptance position or a small area around the verification acceptance position. It is also possible, however, that check comparison parameters are determined for all positions of the entire travel path and only the check
- Comparative characteristic of the review acceptance position or a small area around the review acceptance position is evaluated.
- Verification comparative characteristic value determined. After determining the review benchmark or the review
- Comparison parameters are decided in the subsequent decision phase depending on the one check comparison parameter or the plurality of check comparison parameters, as the method is continued.
- the check acceptance position can be the current one
- Position of the elevator car can be determined In this case, the method has been successfully completed since the current position of the elevator car has been determined reliably.
- This option is chosen in particular when a check comparison characteristic value fulfills a decision determination criterion and is optional other conditions are met. In other words, this option is selected if it has been confirmed in one or more review and decision phases that a start-accept position determined in the start phase has coincided with the actual start position of the elevator car.
- a verification comparison characteristic value fulfills, for example, the decision determination criterion if it is greater or less than a second threshold value, which can be the same as or different from the above-mentioned first threshold value of the start evaluation criterion.
- Determination criterion met This makes it particularly safe to determine the position of the elevator car.
- This option is chosen in particular if one review comparison characteristic value or several review comparison characteristic values meet a repeat evaluation criterion, but none
- a verification comparison characteristic value fulfills, for example, a repeat evaluation criterion if it is greater than a third and smaller than the above-mentioned second threshold value.
- the second option is also chosen in particular when a number of check acceptance positions fulfill the decision-determining criterion mentioned or a check-acceptance position indeed fulfills the decision determination criterion but one of the other conditions mentioned is not fulfilled. In other words, this option is chosen if more than one check acceptance position is the actual position of the elevator car or if a check acceptance position is still possible as the actual position, but a further check is necessary.
- the further checking phase can in particular be carried out in the same way as the previous checking phase. However, it is also possible that another inspection travel path or another method for determining the inspection Comparative characteristic value is used.
- the further decision phase can in particular also be carried out in the same way as the previous decision phase. However, it is also possible that other evaluation criteria or conditions are used. As a further, third option, a decision can be made
- the check acceptance position excluded if the assumption that a start acceptance position determined in the starting phase has coincided with the actual starting position of the elevator car has turned out to be incorrect. After the process has been terminated, the elevator car can be moved a short distance and the process can be started again.
- the check acceptance position is only determined as the current position of the elevator car in the decision phase if at least one additional, independent of the check comparison characteristic value
- Elevator cabin is correctly determined, particularly high.
- a travel distance between the start position and the current check acceptance position is greater than a definable minimum travel distance.
- the minimum travel distance can be between 5 and 15 cm, for example. This can effectively prevent striking features extending in the direction of travel, such as a scratch extending in the direction of travel, on a guide rail from negatively influencing the determination of the position of the elevator car.
- the procedure described can be used to avoid using only current images that contain the feature mentioned.
- the minimum travel path is chosen in particular so that it is greater than a length a so-called rail clip in the direction of travel.
- the rail clips are used to fix guide rails, from which the images are taken to determine the position of the elevator car, so that the rail clips are also included in the images.
- the rail clips have an edge running in the direction of travel, which can negatively influence the image comparison described. If on the current picture and the
- the images can be wrongly regarded as very similar, since the similarity of the edges mentioned can cover differences in the remaining parts of the images.
- the aforementioned choice of the minimum travel path can be used to ensure that the position of the
- Elevator cabin also use current pictures without rail clips.
- the determination of the position of the elevator car is aborted if an abort criterion is met.
- the execution of the method according to the invention is terminated as soon as the abort criterion mentioned is fulfilled. Since the elevator car is moved during the checking phase, this can effectively prevent the elevator car from accidentally reaching the limits of the permissible travel range.
- the total travel path is understood to mean the path between the start position of the elevator car in the start phase and the check position in the last check phase. If the elevator car is always moved in the same direction during the inspection phases, the total travel distance corresponds to the sum of the individual
- Verification paths The maximum travel distance is, for example, between 15 and 30 cm.
- the determination of the position of the elevator car is restarted after an interruption, the elevator car being moved in the opposite direction in the checking phase compared to the checking phase before the interruption.
- the method in the opposite direction can reliably prevent the elevator car from reaching a limit of the permissible in the subsequent checking phases Travel range comes.
- at least one verification travel path in a verification phase, in particular in the first verification phase is chosen to be different from the verification travel paths before the restart. So that will
- Consistency-indicating verification comparison characteristic belongs.
- the position of the elevator car can thus be determined particularly precisely, since any
- Said area can extend, for example, 1 - 5 mm up and down around the check acceptance position.
- a check comparison characteristic value is then determined for all possible positions in this area.
- Verification comparison characteristic value adopted as the current verification acceptance position adopted as the current verification acceptance position.
- the currently recorded image is also compared with the stored comparison image transversely to the direction of travel in order to determine the current position of the elevator car in the direction of travel.
- the position of the elevator car can thus be determined particularly robustly.
- the position of the elevator car in the direction of travel in the elevator shaft can thus be reliably recognized even if the elevator car is not absolutely is always moved exactly along an identical travel curve in the elevator shaft, i.e. there may be different deviations of the travel curve across the direction of travel.
- the elevator car is guided by a combination of a guide device arranged on the elevator car, for example in the form of guide shoes and guide rails fixed to the shaft walls of the elevator shaft, this guide always has a little play, which leads to slightly different travel curves within, in particular when the elevator car is loaded differently of the elevator shaft. This then means that the image capture unit does not always record exactly the same sections of the shaft components or shaft equipment in relation to the direction transverse to the direction of travel on different journeys.
- the combination of comparison in and across the direction of travel can also be used to reliably determine the different driving curves described the position of the elevator car.
- Direction of travel can be understood that the current image or at least a part of it and the comparison image or at least part of it are shifted and compared pixel by pixel transversely to the direction of travel.
- the currently recorded image and / or the comparison image extend in the direction of travel and transverse to
- Direction of travel i.e. have several adjacent pixels both in the direction of travel and transversely to the direction of travel.
- the Comparison characteristic value, the check image with the comparison image also compared to the direction of travel.
- the comparison characteristic value which indicates the greatest agreement is then used as the verification comparison characteristic value for the subsequent decision phase.
- Elevator cabin are compensated transversely to the direction of travel, which enables a particularly robust determination of the check comparison parameters and thus also the position of the elevator car.
- the elevator car is in the review phase
- the lower speed mentioned can be, for example, between 10 and 20% of the speed of the elevator car in normal operation.
- further information that can be detected in the elevator shaft is evaluated to determine the position of the elevator car.
- the position of the elevator car can thus be determined particularly reliably.
- Further information that can be recorded in the elevator shaft is to be understood here to mean information that is true for the
- Operation of the elevator system are required, but are normally not used for determining the position of the elevator car. This includes, for example, the detection of an expert who is arranged in the vicinity of a floor and is used for the exact positioning of the elevator car on a floor. If such an expert is recognized, for example, by means of a special sensor, everyone can

- the computing unit is designed to carry out the following directly or indirectly:
- An “indirect design” by the computing unit is understood to mean that the computing unit controls another component of the system for determining the position of an elevator car in such a way that the desired result is achieved.

- the suspension element 16 extends from the elevator car 14 via a
- Elevator car 14 can be moved up and down in the elevator shaft 12.
- the elevator car 14 can thus be moved in or against a direction of travel 22 which runs upwards in the vertical direction in the elevator shaft 12.

- the system 28 has one computing unit 30 and one
- Image acquisition unit 32 This is designed as a digital camera
- Image capture unit 32 is oriented so that it can capture images from the guide rail 26. It transmits the images of the guide rail 26 consisting of individual pixels to the computing unit 30, which compares a currently recorded image with at least one stored comparison image of the guide rail 26 in order to determine a current position of the elevator car 14 in the direction of travel 22.

- Comparison images for a so-called relative and a so-called absolute position determination are stored in a memory (not shown) of the computing unit 30.
- a large number of comparison images 34 are used for the absolute position determination
- comparison images 34 are derived and stored during a so-called Lemfahrt when the system 28 is started up from current images of the image acquisition unit 32.
- the arithmetic unit 30 derives individual comparison images 34 from the images recorded by the image acquisition unit 32 and assigns them a position in the elevator shaft 12.
- the computing unit 30 derives the comparison images 34 in such a way that they overlap each other twice. In particular, they overlap in such a way that two comparative images after next to one another touch each other.
- the stored comparison images 34 thus cover the entire travel path of the elevator car 14.
- comparison images 34 are recognized in a current image 36 of the image acquisition unit 32, the position of the elevator car 14 in the direction of travel 22 can be inferred with the aid of the likewise stored position of the comparison image 34 in the elevator shaft 12.
- the comparison images are selected as a function of the position of the elevator car 14 at a previous point in time of determination and the speed of the elevator car 14. The number of comparison images required for the comparison is thus very severely limited.
- the currently recorded image of the Processing unit 30 reworked.

It is assumed below that the comparison image 34 is contained in the current comparison area 38.
- the computing unit 30 compares the comparison image 34 and the current one
- the comparison image 34 is shifted pixel by pixel both in the direction of travel (z direction) and transversely to the direction of travel (x direction) with respect to the current comparison area 38, and a comparison characteristic value for each position in the form of a correlation coefficient between the comparison image 34 and that under the comparison image 34 lying image of the
- Correlation coefficient is a measure of the correspondence of the comparison image 34 with the current comparison region 38.
- the shift of the comparison image 34 is symbolized in FIG. 2 by the arrows 40.
- the correlation coefficient is calculated using the following formula:
- T (r, s) mean value of all pixel values of the current comparison area under the comparison image shifted by r in the x direction and s in the z direction.

- a start comparison parameter in the form of a cross-correlation coefficient described above. This will be a comparison with everyone
- FIG. 4a The result of such a determination is shown very schematically in FIG. 4a.
- the associated cross-correlation coefficient is shown as point 52 for the different positions (plotted along the h axis) (plotted along the k axis). The larger the cross correlation coefficient, the more similar the comparison image of this position is to the current image.

For these two
- Check-acceptance positions PA1.1, PA2.1, check-comparison parameters are determined in the form of the cross-correlation coefficients described above. For this purpose, a comparison of the check image with the comparison images of the check acceptance positions PA1.1 and PA2.1 (comparable to 34 in FIG. 2) is carried out. As described above, the images can be shifted against one another only in the z direction or in the z direction and x direction.
- the two check comparison parameters 58a, 58b are shown in FIG. 4b. In a subsequent decision phase it is decided how the procedure is to be continued. First, it is checked whether the two check comparison characteristic values 58a, 58b meet a decision-determining criterion.
- a second threshold value which is shown as line 60 in FIG. 4b.
- the second threshold is identical to the first threshold of the start phase.
- Both check comparison characteristic values 58a, 58b are smaller than the second threshold value, so that at this point in time neither of the two check acceptance positions PA1.1, PA2.1 is determined as the actual, current position of the elevator car 14.
- the threshold value is smaller than the second threshold value. This is only for the
- Check comparison characteristic 58a of the first check acceptance position PA1.1 is the case.
- Check acceptance position PA2.1 is less than the third threshold. Since the first verification comparison characteristic value 58a fulfills the repetition evaluation criterion, a further verification phase and a further decision phase are carried out for the associated verification acceptance position PA1.1. Since the second verification-comparison characteristic 58b also that
- Acceptance position PA2.1 is excluded as a possible current position of the elevator car 14.
- Verification phase before the termination in the opposite direction that is to say upwards, in particular, at least one verification travel path is moved in one
- Verification phase in particular in the first verification phase, selected differently from the verification travel paths before the restart.
- the method is continued so that the first decision phase is followed by a further, second verification phase.
- This runs analogously to the first check phase described above, with only one check acceptance position PA1.2 resulting from the check acceptance position PA1.1 and the check travel path sl.
- the resulting check comparison parameter 64 is shown in FIG. 4c.
- a decision is again made as to how the procedure is to be continued.
- the check comparison characteristic 64 fulfills the decision-determining criterion.
- it is checked whether it is greater than the second threshold value, which is also shown as line 60 in FIG. 4c.
- the Verification comparison characteristic value 64 is greater than the second threshold value, so that decision-determining criterion is met.
- a decision criterion which is independent of the verification comparison characteristic value 64 is then checked. For this purpose, it is checked whether a travel path s2 between the
- Start position 50 and the current check acceptance position PA1.2 is greater than a definable minimum travel path. This is the case here, so that the check acceptance position PA1.2 is determined as the actual, current position of the elevator car 14. This has confirmed the assumption that the first start acceptance position PS1 corresponded to the start position 50 of the elevator car 14 in the start phase.
- the acceptance position for the subsequent decision phase is then the position which belongs to the verification comparison characteristic value which indicates the greatest agreement.
- the position for which the largest cross-correlation coefficient is obtained is therefore used.
- Further information that can be detected in the elevator shaft can also be evaluated. For example, an expert (not shown) can be detected, who is arranged in the vicinity of a floor and is used for the exact positioning of the elevator car on a floor. If such an identifier is recognized, for example, by means of a special sensor, all check acceptance positions that are not in a possible area of such an identifier can be excluded.
