Definitions

  • the invention relates to an elevator device for the transport of persons and / or objects within an elevator shaft of a building or the like according to the preamble of claim 1 and a building according to the preamble of claim 12, further a position determination device according to the preamble of claim 15.
  • Elevators or elevator systems for buildings are known from the prior art, in which the position of the elevator car of the elevator car is detected by means of a magnetic tape.
  • This magnetic tape is regularly attached to the mobile scaffold or on a guide rail of the mobile scaffold.
  • This mobile scaffold is used to guide or support the elevator cage, d. H. the mobile scaffold provides a guide for the elevator cage, in which the elevator cage can be moved or moved.
  • the object of the invention is to provide an elevator device, a position determination device or a building, in which an improved position determination of the elevator cage is made possible.
  • an inventive invention Elevator device characterized in that the marking unit as a carrier of a bar code, in particular a 2-D code and the detection unit as an image sensor, in particular as a camera, are formed.
  • the elevator device serves to transport persons and / or objects within an elevator shaft of a room structure or the like.
  • a room structure can be a building.
  • Under a building according to the invention is any kind of structure to understand, for example, a house, a high-rise, a tower, a hall, a stadium with a tribune, a warehouse, a transport or loading station or the like. But it can also be another, at least two floors comprehensive spatial structure.
  • a spatial structure may, for example, also be a vehicle which has a building-like structure, for example a ship.
  • elevator devices in mobile transport or lifting devices Such an elevator device has a lift cage in which the persons and / or objects to be transported can be accommodated. The elevator cage is moved within a mobile scaffold for storage or guidance of the elevator cage.
  • the mobile scaffold is installed inside a lift shaft.
  • a position determining device In order to determine the position of the elevator cage within the elevator shaft or with respect to the mobile platform, a position determining device is provided. This comprises at least one marking unit for marking the position, furthermore a detection unit for detecting or reading out the marking unit and an evaluation unit for evaluating the measured values of the detection unit.
  • This evaluation unit can be designed, for example, as an electronic unit which outputs output measured values of the detection unit and uses them to derive a position information about the position of the elevator cage with respect to the mobile structure or the position within the elevator shaft.
  • the position determination can be improved.
  • a bar code or a 2-D code makes it possible to carry out a simple and cost-effective marking.
  • Such a mark can be printed, for example, simply and inexpensively.
  • Such a mark can also be read out with standard scanners or other image sensors provided for this purpose. In addition, this allows a particularly error-free reading. Since the corresponding barcodes or 2-D codes can be imaged very sharply and can also be placed very precisely in relation to the mobile scaffold or the elevator shaft and on a very precise image sensor detection is possible, the position can also be determined very precisely become.
  • barcodes or 2-D codes have a correspondingly high black-and-white contrast, these markers are regularly less susceptible to contamination such. By dust.
  • a maintenance or error signal can be output, for example, from the evaluation unit, in which also the contrast can be determined.
  • a barcode or 2-D code can advantageously be read without contact and is also practically wear-free.
  • a correspondingly accurate detection is made possible by image sensors having a corresponding optics such as telecentric lenses. Furthermore, it is possible to provide the most compact and small image sensors available.
  • the marking unit is further formed as a band, this measure, allows a continuous marking of the position on the route of the elevator car.
  • Each individual marking can be separated from the next marking by a corresponding symbolism, for example a separating strip, so that a fine screening is also made possible.
  • the marking unit is mounted on the mobile scaffold, in particular on a guide rail of the mobile scaffold.
  • the mark is not obscured, for example, by struts or the like when the elevator car passes by.
  • this measure also enables a simplified installation or maintenance.
  • no influence must be taken into account with regard to a measurement that could be caused by a change in the distance between the marking strip and the sensor. In most cases, a small distance between the marking strip and the sensor makes it possible to determine the position precisely.
  • Building structures can also "set" over time after they have been built, which means, for example, that walls can change their position and move easily. Such changes are known in construction technology and building physics and caused for example by aging or stress. Also conceivable are changes due to seismic activity or other changes in the subsurface (due to subsidence, groundwater, etc.). However, these shifts are not always linear or even. If such a shift occurs, it may mean that the building is being moved in a different way than, for example, the chassis in which the elevator cage is being guided. A further advantage of the attachment of the marking unit to the mobile scaffold can consequently be that at least partial decoupling of the position of the marking unit from displacements of the building is made possible.
  • a corresponding marking unit is fastened directly to the building, for example to a wall of the building, this can change its relative position with respect to detection by an image sensor of a lift cage movable in the mobile scaffolding. If this effect were not taken into consideration, this could lead to determining the position after a certain time, in which the building or individual walls move, would be more inaccurate than when installing the elevator; Accordingly, if appropriate, the shaft opening could no longer be approached precisely by the elevator car.
  • the marking unit can also be mounted on the elevator shaft or on another part, for example a wall of the building.
  • a second marking unit can be used as a reference mark for adjusting the accuracy of the first marking unit.
  • the evaluation unit can perform such a comparison, if necessary automatically at certain time intervals.
  • the elevator device can determine whether there has been a change with respect to the relative position relative to one another with time between the first marking unit and the second marking unit.
  • This can be used for maintenance purposes, but also for building security.
  • this can be a calibration the position determining device are made so that an even more precise position determination is made possible. Such a calibration can be carried out in the evaluation unit.
  • the second marking unit may, for example, be mounted near the shaft opening, for example per floor.
  • a second marking unit can also be used to transmit further information.
  • the second marking unit can be used to mark a specific zone on the route within the elevator shaft.
  • the evaluation unit can in turn be designed to determine whether the car or the elevator car is located within this zone or not.
  • a derarsige zone may be, for example, the area around a shaft opening around, in which an exit is possible from in the Aufzugekorb persons.
  • a shaft opening is present in each floor, optionally also two manhole openings, if, for example, an exit to opposite sides is possible.
  • an unlocking device for unlocking a door or an exit hatch of the elevator car which is controllable by means of the evaluation device, be negotiate.
  • the purpose of such unlocking is to allow an emergency exit in case of a defect of the elevator, but only if the elevator car is located in the region of a shaft opening.
  • the unlocking device unlocks a door of a shaft opening of the elevator shaft, so a door that is not mounted directly on the elevator car.
  • a control within the meaning of the invention means a control and / or control. For example, depending on whether or not the elevator cage is inside the zone, the unlocking device is activated or not.
  • the detection unit may be arranged in an embodiment variant on and / or under the car. It is also conceivable that the detection unit is attached to another position on the car. This means that the marking unit is fixed, for example on the running rail or on the building itself, while the car, which can perform a movement relative to this marking unit, has the corresponding detection unit, which then depending on their position with respect to the Marker unit corresponding position information can supply the evaluation device. In principle, however, it is conceivable that the detection unit is also mounted, for example, laterally on the elevator car. In general, the position of the detection unit relative to the car, inter alia, in the evaluation of the position of the car by the evaluation device to be considered, d. H. this must be configured accordingly or preprogrammed accordingly.
  • a building according to the invention with at least two floors is characterized in that an elevator device according to one of the preceding claims is provided.
  • the second marking unit is attached to the building.
  • a relation between the mobile scaffold or the rail of the mobile scaffold and the building is advantageously made possible in particular.
  • this relative position between the building and the rolling stand can be redetermined at any time, even if there is a non-uniform change, and a renewed calibration can be carried out.
  • a corresponding warning function for example, from the evaluation unit, is activated if this change in position is too strong.
  • This second marking unit can also carry, for example, floor information and position information. For example, it may contain the number of the single floor in coded form.
  • the position information can be represented in various ways: First, there is the possibility of point information, which can be used in principle for calibrating the code band, but also for calculating a position, for example, the zone in which an unlocking is to take place. Furthermore, an area information can be encoded, which z. B. enables direct detection of the unlocking zone. Such an area may be defined by a beginning and an end, for example, in the case of an unlocking zone, an area of about 20 cm below a manhole opening to 20 cm above a manhole opening. In principle, it is conceivable, for example, to detect the beginning or the end of an unlocking zone directly on the basis of a coding on the marking unit.
  • a length information can be transmitted, which can be used for a calibration of the code band, but can also lead to increased accuracy, if the vernier principle is exploited. Accordingly, in principle both an indirect and a direct detection of the unlocking zone is conceivable.
  • floor information can also be coded.
  • Image sensors can basically be used to read out the first and also the second marking unit.
  • the marker units can also be used to define a breakpoint of the elevator cage.
  • the floor information can basically be omitted if a position can be assigned to the code read out from the marking unit by the memory of the evaluation unit.
  • the corresponding information or assignment table is then to be stored accordingly, for example in the memory of the evaluation before.
  • the floor information can also be obtained by having a read out breakpoint information is detected and marks are read from an extreme position during a learning phase while driving. This measure enables good technical feasibility and cost-effective implementation.
  • the second marking unit is arranged such that the zone marked by it forms an area around at least one of the shaft openings of the elevator shaft.
  • This zone may, for example, serve as an unlocking zone, i. H.
  • an emergency release can be made if the elevator stops, for example due to a technical defect or other unforeseen event. With the help of the emergency release then the doors can be brought in a safe for the persons or the transporting objects area through a manhole opening from the car. By this measure, the safety of the elevator device can be increased.
  • FIG. 1 shows an elevator device 1 with a mobile scaffold 2 and a lift cage 3.
  • the elevator cage 3 carries on its underside a camera 4.
  • On the mobile scaffold 2 a Vietnamese marking unit 5 is mounted.
  • the elevator 1 in turn is located in a building 6, the building 6 in turn comprises an elevator shaft 7, in which in turn the elevator device 1 is arranged.
  • a shaft opening 8 In a wall of the Building 6, which adjoins the elevator shaft 7, in turn is a shaft opening 8.
  • a second marking unit 9 is attached to the wall of the building 6.
  • This embodiment is a preferred embodiment.
  • the camera 4 is designed as an image sensor to basically detect and read both the first and the second marking unit. Persons can pass through a shaft opening 8 in the car 3, if this is at the appropriate height, more precisely at the corresponding position in height of the shaft opening 8. In the car 3, the persons can be transported in the vertical direction.
  • the elevator cage 3 in turn is supported and guided by the chassis 2. Furthermore, the car 3 includes doors that automatically open and close when the car has reached a corresponding position, for example at the level of the shaft opening 8.
  • the camera 4 When driving the elevator cage 3 in the vertical direction, the camera 4 receives corresponding images of the first measuring unit. These image information received by the first measuring unit are processed in the evaluation unit (not shown) and finally result in a position specification of the elevator car 3 within the chassis 2. Both the second marking unit and the first marking unit contain a barcode or 2-D code to be read out , The image area which the camera 4 detects, however, also makes it possible to read the second marking unit if it can be detected by the camera 4, which in turn depends on the position of the elevator cage 3. As in FIG. 1 illustrated, the camera 4 can then detect the second marking unit when the car 3 is in the region of the shaft opening 8.
  • Both the second marking unit and the camera 4 on the elevator car 3 are mounted so that the second marking unit at the shaft opening 8 can then be read when the Lift cage 3 is about 20 centimeters above or below the normal position at the level of the shaft opening 6, usually takes place in an exit from the car. This is the case when the floor of the car is level with the floor at the shaft opening. This zone 20 centimeters above to 20 centimeters below the normal holding position at the level of the shaft opening 8 in turn forms a Entriegelungszcne. In the area of this unlocking zone, an emergency release can take place in permissible manner. Such an emergency release is necessary when the car 3 stops suddenly, for example as a result of an unforeseen event, a power failure, a blockage of the elevator or the like.
  • the persons can then be released from the pull-out basket 3 without any special danger, if this is located in a corresponding zone which is located close enough to the shaft opening 8.
  • this zone the unlocking zone, is located about 20 centimeters above or below the shaft opening 8.
  • the first marking unit is formed as a band carrying the bar code; Meanwhile, the second marking unit is formed as a 2-D code, wherein the marking unit is formed by a marking piece.
  • these marking units can be formed by an adhesive strip which carries the corresponding marking or the corresponding bar or 2-D code.
  • FIG. 3 shows an example of a corresponding marking unit, namely a code tape 10.
  • the area 11 can serve as floor coding
  • the area 12 as a position coding
  • the area 13 as unlocking coding.
  • marking lines 14 may also be present.
  • An encoding pattern in the 2-D code is shown by way of example in FIG.
  • the marker lines 14 may occur at periodic intervals.
