Definitions
- the invention relates to a method and a system for determining the position of an elevator car arranged in a lift cage arranged elevator car of an elevator system according to the preamble of the independent claims.
- Manhole components are set as markers, which are recorded by the camera and processed by a computer connected thereto.
- the disadvantage here is that a learning journey is necessary in order to be able to assign the manhole components to an absolute position of the elevator car.
- an absolute position determination with such a system is associated with a high computational effort.
- Elevator shaft arranged movable elevator car of an elevator system, wherein the elevator car is equipped with an acceleration sensor, comprises the following steps.
- the acceleration data is acquired from the
- Acceleration sensor by a computing unit. This is followed by a calculation by the arithmetic unit of the current position and / or speed of the
- Elevator car starting from an initial position and the detected
- the position or speed of the elevator car is thus determined in accordance with an inertial navigation system.
- delays and errors may occur which affect the reliability of position determination.
- vibrations of the elevator car from the acceleration sensor can not be clearly assigned to a movement or a fault, so that in the end result the calculated position will deviate from the actual position. This is referred to as a "drifting" of the calculated position data with respect to the real position of the elevator car.
- the acceleration sensor is preferably designed as a 3-axis sensor. Other sensor configurations are conceivable. However, it is important that the in
- the elevator system is equipped with an image acquisition unit.
- the image acquisition unit is attached to the elevator car and arranged to be movable together with the elevator car.
- the computing unit compares the erfmdungsge insomniass
- the arithmetic unit takes a
- Mapping images are images that, in their entirety, represent an image of the elevator shaft.
- the mapping images are preferably taken during a learning run during the commissioning of the elevator and clearly assigned to a position of the elevator car in the elevator shaft, so that the later
- mapping images stored with the assigned position values in a database.
- the determination of the current position thus takes place initially by means of the calculated current position by the acceleration data obtained by the acceleration sensor until an image-based current position is again determined and the current position is recalibrated.
- a so-called “drifting" of the calculated current position is counteracted by the image-based current position
- Preferred are in a predetermined or predetermined first time interval
- Image taken of the elevator shaft of the image capture unit Two consecutively recorded images are compared by the arithmetic unit to determine a spatial displacement of both images, wherein for determining the position and / or speed of the elevator car the
- Acceleration data can only be used if a spatial
- Shift has been determined by the arithmetic unit based on the recorded images.
- the images compared by the arithmetic unit need not necessarily be recorded immediately one after the other.
- the images are preferably recorded only when the acceleration sensor measures acceleration data of the elevator cars. This ensures that the arithmetic unit does not constantly have to compare images from the image acquisition unit but a comparison only in case of detection of acceleration (and therefore possible movement) by the acceleration sensor.
- Acceleration data with a frequency of 100 Hz are preferably recorded.
- Images are preferably recorded at a frequency of 60 Hz.
- the images are recorded only if the
- Acceleration data are above a predetermined or predefinable threshold.
- Acceleration sensor e.g. during the loading and unloading of the elevator car, do not trigger the image acquisition unit. It is thus possible to use a relatively inexpensive and simple arithmetic unit, as they do not process continuously image recordings and may need to save.
- Acceleration data which are above a predefined or predefinable second threshold value are preferably rejected by the arithmetic unit.
- acceleration data which are above the second threshold, and which experience has caused by disturbances are not taken into account. For example, accelerations greater than 1 g, which occur during emergency braking of the elevator car, be excluded, since in this case it is ensured by an emergency brake that the elevator car to
- the current position is recalibrated if a deviation between the image-based current position and the calculated current position is above a predefined or predefinable threshold value.
- the image-based current position which has been directly and uniquely determined, is set instead of the calculated current position (which has been determined indirectly via the acceleration data).
- the recalibration of the current position with the image-based current position may occur at a second interval.
- each time the captured images are compared with the mapping images, where an image-based current position is determined the current position is recalibrated. This recalibration thus takes place continuously at second intervals.
- the image-based current position is therefore preferably determined with images recorded in a predefined or predefinable second time interval, the second time interval being greater than or equal to the first time interval. Also in this case, a relief of the arithmetic unit is achieved. Not all of the
- Image capture unit recorded images used for the determination of the image-based current position and thus reduces the computational complexity of the computing unit.
- the second time interval is particularly preferably in the range between 500 and 100 ms, which corresponds to a frequency of 2 to 10 Hz.
- mapping images are preferably stored in a database during the learning run of the elevator car.
- This database is connected to the arithmetic unit.
- a memory address of a mapping image in the database is defined as a function of the position along the hoistway.
- the arithmetic unit uses the calculated current position to narrow a search of a mapping image in the database.
- mapping image associated with the captured image can be found more quickly in the database.
- the advantage of this is even twofold, because a mapping image can not only be found faster, but the computing capacity of the arithmetic unit can also be further reduced.
- the invention furthermore relates to a system for determining the position of an elevator car of an elevator system which can be moved in an elevator shaft.
- a system may preferably be operated by a method mentioned above. It is therefore apparent that the advantages mentioned above with regard to the method according to the invention also apply correspondingly to the system according to the invention.
- the elevator car is equipped with an acceleration sensor.
- the system further comprises a computing unit, which is designed to detect acceleration data from the acceleration sensor and to calculate a current position and / or speed of the elevator car based on an initial position and the acquired acceleration data.
- the system further comprises an image acquisition unit, which is designed to record image recordings of the elevator shaft and to transmit them to the arithmetic unit.
- the arithmetic unit is configured to compare captured images with mapping images of the elevator shaft to determine an image-based current position and to recalibrate the current position using the image-based current position.
- the image acquisition unit is further configured to record image recordings of the elevator shaft at a predefined or predefinable first time interval and to transmit them to the arithmetic unit.
- the arithmetic unit is designed to compare two consecutively recorded images with one another in order to determine a spatial displacement of both images and to use the acceleration data for determining the position and the speed of the elevator car only if a spatial displacement is determined by the arithmetic unit becomes.
- the arithmetic unit is adapted to the image acquisition unit for
- Elevator car to be detected.
- the arithmetic unit is designed to detect acceleration data only if they are above a predetermined or specifiable threshold value. More preferably, the arithmetic unit is designed to discard acceleration data which are above a predetermined or predefinable second threshold value.
- the arithmetic unit is designed to, if a deviation between the current image-based position and the current position is above a predetermined or predeterminable threshold, the current calculated position with to recalibrate the current image-based position.
- Arithmetic unit adapted to recalibrate the current position in a second time interval with the image-based current position.
- the arithmetic unit is adapted to the image-based current position with in a predetermined or predetermined, second time interval
- a database which is designed to store mapping images that were generated during a learning trip of the elevator car.
- a memory address of a mapping image in the database is defined as a function of the position along the elevator shaft.
- the arithmetic unit is designed to limit a search of a mapping image in the database using the calculated current position.
- the invention further relates to an elevator installation which is equipped with an abovementioned system for determining the position of the elevator car.
- FIG. 1 shows a schematic sectional view of an exemplary embodiment of an elevator installation with a system according to the invention for determining the position
- FIG. 2 is a detailed view of an exemplary embodiment of the cantilever of FIG. 1;
- Fig. 3 is an exemplary image comparison of two consecutive
- Fig. 5 is a graphical representation of the calculated and image-based position
- FIG. 6 shows an exemplary QR code which serves to indicate a floor position.
- an elevator system 3 is shown, which with a
- inventive system 7 is equipped to determine the position.
- Elevator system 3 comprises an elevator car 2, which is arranged to be movable in an elevator shaft 1 along an axis z. Not shown are any carrying and traction means, which are used for carrying and moving the elevator car 2 application.
- the elevator car 2 is further provided with an acceleration sensor 4, which is connected to a computing unit 5.
- Acceleration sensor 4 and the arithmetic unit 5 is shown schematically with a dashed line. This can be a direct connection via cable, for example with a bus system, or even a wireless connection.
- the arithmetic unit 5 is arranged on the elevator car 2. However, the arithmetic unit 5 does not necessarily have to be arranged in the elevator shaft 1.
- the acceleration sensor 4 measures those occurring in the elevator car 2
- the elevator car is further equipped with a camera 6, here by way of example a CCD camera, which is attached to the elevator car 2 by means of a boom 9.
- the boom 9 allows adjustment of the orientation of the camera 6 and also allows retrofitting in existing elevator systems.
- the camera 6 is also connected to the arithmetic unit 5, as shown schematically by the dashed line.
- a Headlight 8 for example, an LED headlight, arranged on the boom 9.
- the camera 6 can thus record a sufficiently illuminated area of the elevator shaft 1, which improves the quality of the image recordings and consequently the
- the camera 6 can be pivoted for adjustment about a pivot axis, as indicated by the double arrow 10.
- the headlight 8 can be both a
- Pivot axis 11 pivoted and moved along the boom 9, as indicated by the double arrows 11 and 12 respectively.
- the camera 6 is operated at a recording rate of 60 Hz.
- a recording rate of 60 Hz By comparing two consecutively recorded images B 1 and B2, it can be determined whether a shift ⁇ of the images in the z direction has taken place.
- FIG. 3 shows such a displacement ⁇ between two consecutively recorded images B1 and B2.
- FIG. 3 shows by way of example a displacement ⁇ on the basis of a fastening element 19.1, 19.2.
- the fastening element 19.1 appears in the lower area of the first image Bl. In the second picture B2 this appears
- the displacement ⁇ determined in the images B1 and B2 thus corresponds to a downward travel of the elevator car 2 by ⁇ .
- This comparison is preferably made on the basis of a gray value comparison of the two images Bl and B2. It can therefore be determined whether the elevator car has been moved in the z direction.
- These optically determined data are used to supplement the data from the acceleration sensor 4.
- a position zt of the elevator car 2 can be derived.
- a movement at a constant speed is not detected by the acceleration sensor 4, since in this case the measured acceleration of the elevator car is zero. Due to the optical motion detection, however, a distinction can be made between standstill and movement of the elevator car 2.
- Elevator car 2 is optically detected.
- FIG. 4 shows the data acquired by the acceleration sensor 4. With Dg, a curve of the acceleration of the elevator car 2 measured by the acceleration sensor 4 is shown. When the car is at a standstill, the of the
- Acceleration sensor 4 measured acceleration 9.81 m / s2. By integrating the acceleration Dg, the velocity vt and the inertia-based position zt can thus be calculated, which are also shown in FIG. 4 in m / s and m, respectively.
- mapping images from a database Compared to mapping images from a database.
- the mapping images from the database have been taken during a learning trip, for example, during startup of the elevator system 3, and clearly a position of
- Elevator car 2 has been assigned in the elevator shaft 1. It is thus possible to determine the position eg of the elevator car 2 on the basis of a direct, image-based measurement and not as usual by means of indirect methods.
- the arithmetic unit searches the database for a matching mapping image with the aid of a calculated current position.
- the search on the database can be greatly restricted since the memory addresses of the mapping images are formed as a function of the position along the elevator shaft 1.
- the accuracy of indirect methods such as, for example, an incremental disk or a magnetic tape coding decreases.
- the system 7 is not affected by such a decrease in accuracy because the visually determined, image-based position zBt is independent of the above confounding factors.
- the current image-based position eg, which has been optically determined as described above, is further used to correct the position zt calculated by means of acceleration data from the acceleration sensor 4.
- the position is recalibrated For example, the optically determined, image-based position is set as the current position
- Acceleration sensor 4 as described above used to further determine the position zt of the elevator car 2. It may thus be based on the use of other positioning systems such as e.g. an incremental disk or a magnetic coding are dispensed with. In addition, such a recalibration at any time and not as usual only at the top or bottom stop one
- Elevator car 2 possible.
- the recalibration of the current position zt at intervals t2 between 100 to 200 ms at each comparison of a recorded image with mapping images, in which an image-based current position is determined can take place.
- FIG. 5 shows the sequence of such a recalibration, wherein the right-hand diagram represents an enlargement of the framed area of the left-hand diagram. It can be seen that the calculated, inertia-based position deviates zt over time from the optically determined, image-based position z. If the
- Deviation is above a threshold, the calculated, inertia-based position zt recalibrated zt by the optically determined, image-based position zBt is set as the current position of the inertia-based positioning system, as indicated by the arrow 14. The position is then determined as described above until the deviation between the optically determined, image-based position zBt and the calculated, inertia-based position zt again reaches the threshold and a new recalibration takes place, as indicated by the arrow 14 '.
- FIG. 6 shows a schematic representation of a section of the elevator installation 3 at a floor 17, wherein the figure 6 shows a situation in which a
- Elevator car 2 in the shaft 1 in a vertical drive in the direction of z in terms of the floor 17 is approach.
- the shaft 1 is opposite the floor 17 by a shaft door 16 lockable.
- Elevator car 2 a car door 15 is provided.
- the floor 17 is marked with a floor marking 18, here exemplarily designed as a QR code, which in the
- the camera 6 is mounted on the boom 9, which is fastened, for example, to the cabin floor 2.1 of the elevator car 2.
- the floor marking 18 is preferably characteristic of each floor 17, so that due to the detectable by the camera 6
- Floor markings 18 an automatic detection of the floor positions of all
- the image markers 18 recognized imagewise by the camera 6 can also be stored in a learning run as mapping images KB and are stored accordingly in the database.
- Images are particularly easy assignable to a mapping image KB, so that a calibration of the calculated current position zt in the field of
- Floor markings 18 is particularly robust. In a temporary failure of the system 7 thus the floor marker 18 can also serve as a catch point or
- the QR code 18 is important for flawless detection of floor positions.
- the QR code 18 has a dimension of at least 3cm x 3cm with an optimum range of dimension between 4cm x 4cm and 6cm x 6cm. In the case of even larger QR codes, recognition is likewise ensured, but only with a correspondingly large field of view of the camera 6.
- Elevator system 3 which is upgraded by software update or addition of a hardware module.
- floor markings 18 in the shaft 1 at the floors 17 can be arranged. This is followed by a learning run, in which the mapping images of the elevator shaft 1 are taken and assigned to a position of the elevator car 2.
- Such a system 7 allows a very accurate position determination with errors less than 0.5 mm at elevator speeds up to 5 m / s.
