Description

The invention relates to an elevator to be checked at intervals with a test certificate.

Recurring safety tests, type tests, conformity tests and the like must be carried out on elevator systems by authorized testing organizations or other persons. A test certificate with a test certificate is generally issued by handing over a written test certificate to an elevator operator and / or by attaching an often hand-stamped test badge, which is renewed during each test, to a certified lift installation.

The object of the present invention is to facilitate such tests.

According to the invention, this object is achieved by an elevator installation with the features of claim 1. Further advantageous variants and embodiments are specified in the respective subclaims.

The elevator installation according to the invention, which is to be checked at intervals, comprises an electronically readable test confirmation.

Furthermore, a test certificate preferably contains a currently valid certification. A certification is in particular an information about a test status that can be authenticated on the basis of, for example, defined characteristics.

In an advantageous embodiment, a currently valid certification can be renewed multiple times via the test confirmation. Therefore, a test confirmation is preferably used at an elevator installation for several test procedures. The test certificate is preferably a temporarily authenticated electronic test sticker.

In a further development, the test certificate has a time-limited, currently valid certification. Preferably, the test certificate is equipped with a module for time measurement. This is preferably an electronic quartz clock module. Upon reaching a previously definable validity date, for example, on a display or for example by means of an indicator light signals that the validity of the current certification has expired. Furthermore, it is preferably provided that this state can only be reset by a new successful test. In a further variant, the means for time measurement is an indirect time display. For example, the validity of the current certification is displayed based on a degradation effect of, for example, a surface. In another embodiment, a time signal emitted, for example, by a transmission system is used to determine the time. In a further embodiment, the time is determined by a mechanical clock or, for example, via a power supply.

From an electronically readable test confirmation depositable test data are read out, for example, in the test certificate. Preferably, these data are automatically stored in a read-out device and / or evaluation unit, for example a handheld. For example, data transferred to an evaluation unit by means of the test confirmation is used for checking the validity of a test and / or for testing purposes of an elevator installation.

An inspection confirmation can be realized in different ways. By way of example, a test confirmation is a memory chip connected to the system to be tested, the memory contents of which are accessible, for example, contactlessly or, for example, via a plug contact arrangement, which is attached in particular to the elevator installation. In another embodiment, a test confirmation, for example in the form of a separate housing or a sticker on the system to be tested attachable. In addition to electronic memory chips, for example, wire memories or magnetic memories are also used. For example, it is also possible to use RFID chips whose information is read out by means of radio waves.

In a further embodiment, the test confirmation comprises a test sticker. For example, this is a test sticker consisting of one or more printed films. To increase the security against forgery, a test badge preferably consists of a carrier film made of plastic, on which a marking overprint, a grid and a color layer are printed, these layers are covered by an adhesive layer and the color layer is interrupted in a pattern complementary to the grid pattern. With, for example, an integration of preferably a memory chip and a transponder in such a badge, an electronic readability of the test badge is provided.

For example, the Prüfplakette is designed as a flat housing or flat support plate, both preferably made of metal or plastic, wherein individual components of the test confirmation, in particular, for example, components for integrating further specified in particular in the description and in particular described below features and other embodiments are embedded. The test badge is preferably designed as a reusable badge which, for example, remains connected to a system to be tested over a plurality of test procedures and over a longer period of time, preferably several years.

In a further variant, the test confirmation comprises means for storing data. Preferably, a safety-related check of an elevator installation facilitating and / or resulting data, in particular measuring and / or installation and / or test data, can be stored in a memory on the test certificate. Preferably, the stored data can be read out electronically. For example, the test certificate is attached to a system to be tested, so that the data are stored on the system. Data which can be stored on the test confirmation are, for example, measured values measured during a test procedure with a measuring device. In the case of a hydraulic elevator installation, measured values are stored, for example, for measuring a sensor mounted in the pressure transmission medium of a hydraulic elevator installation, and measured with a temperature sensor. In addition, for example, specific system parameters such as an effective piston area and / or rated load of a hydraulic elevator installation are stored in a memory of the test certificate.

By depositing useful equipment parameters and / or previous test results and / or test records on the test certificate preferably attached to the elevator installation to be tested, an inspector can in particular check other various sources of information during their safety testing, such as test protocols previously available in a data processing system and / or in paper form - include in the test certificate. Preferably, a large amount of data may be kept ready for review for checks that are generally only temporary but multi-recurrent and in a variety of different locations, generally different installations.

Preferably automatically automatically deposited data on the test confirmation, for example, for testing and / or evaluation purposes in a test and / or evaluation transmit, so that the risk of erroneous input and / or erroneous assignment of such data is reduced. In particular, a manual input of such data can be at least largely avoided.

In a further embodiment, the means for storing comprise at least one nonvolatile memory and / or at least one rewritable memory. For example, this is a magneto-electronic or realized with an EEPROM memory device memory. For example, it is also wire memory or magnetic memory. By using a non-volatile memory, the memory contents are protected against loss in the event of a power failure of the test certificate.

According to another idea, the test confirmation includes at least one barcode memory. This is preferably a set in a European standard European Article Number Code (EAN) with barcodes for fast and automatic identification of the test confirmation used. In particular, the barcode can also be two-dimensional. Preferably, the barcode is not static, but is shown for example on a display of the test certificate. This barcode contains in particular at least one part, for example, stored in the memory test and / or system data. Furthermore, the content of the barcode is preferably updated during each checking process. To ensure encryption, for example, graphical code can also be hidden by means of steganography in another graphic.

In a further embodiment, the test confirmation comprises means for receiving data. For example, this is a receiving device. Preferably, data, for example a validity date of the current valid certification, is sent to the test confirmation by means of an external transmission device.

For transmission of data, the test confirmation in a further variant comprises means for sending data. For example, this is a transmitting device. Preferably, by means of the transmitting device, data, for example a validity date of the current valid certification, is sent from the test confirmation to an external receiving device. For example, such data is sent to a laptop and / or a handheld and / or a mobile device. In a further refinement, the test confirmation is provided for a plurality of systems, so that, for example, it receives such data from a plurality of systems.

Preferably, the transmitting device and the receiving device are combined to form a transmitting and receiving device.

In a further embodiment, the test confirmation allows a wire, infrared or radio-bound data transmission. In this way, for example, test data from one or more sensors used during a test and also equipped with a transmitting unit are transmitted to the test confirmation. In this way, for example, system-specific data stored on the test confirmation are read, for example, into an evaluation unit of a measuring device.

A wired variant is preferably realized with a plug connection, for example with a serial and / or a parallel and / or a USB interface. Furthermore, for example, a connection can also be made by means of a network cable. An optical data transmission using, for example, an infrared interface is particularly advantageous where electromagnetic interference could affect the wireless or wireless data transmission. A radio-bound variant is particularly advantageous where the communicating transmitter and receiver are difficult to access or far away from each other, so that an optical data transmission is not possible and a laying of electrical lines for communication seems too expensive.

In order to prevent manipulation during data transmission, the data transmission can be combined in an advantageous variant with encryption and / or decryption. The encryption and / or decryption takes place, for example, independently of the data transmission, for example during generation and / or storage and / or during a read-out process of data. For example, data is stored in encrypted form in a memory. In another variant, the encryption and / or decryption is preferably integrated in the data transmission.

Preferably, the data transmission takes place in the form of digital signals. Due to the digital data transmission, preferably equipped with error correction method, in particular a falsification of the transmitted measurement results due to electromagnetic interference is largely avoided. In particular, by suitable methods and algorithms for encryption and decryption known in the prior art, for example with the aid of a 128-bit key, protection against manipulation of the data transmission is ensured.

Preferably, a transmitting and receiving unit is associated with an input / output scan module to account for external data in the input and an output to external receivers. With the aid of the scanning module, e.g. individual input and output data sequentially on or read and are stored for example in a memory. In a further variant, for example, a stream-based data transmission is provided. In this case, a communication preferably does not take place with input and output data separated into individual data packets, but rather with a data stream which may contain data in any order and composition.

In order to ensure an assignment of an electronic test confirmation to a system under test and / or to a measuring device used and / or approved for testing, in addition to data, for example, identification codes are also exchanged in a communication, which are preferably previously determinable. As a result, in particular a manipulation of a test confirmation by, for example, a counterfeit and / or unauthorized measuring device is prevented.

In a further advantageous embodiment, the test confirmation is equipped with a transponder for contactless communication. The energy required for the operation of the transponder is received preferably via an antenna of the transponder at the moment of an electromagnetic remote interrogation, so that preferably no separate power supply is necessary for this communication. The transponder is designed, for example, as an RFID memory chip.

According to another idea, data is exchangeable between the test certificate and a measuring device for testing the elevator installation. Preferably, the data exchange is designed by a suitable communication between test confirmation and measuring device so that it allows at least the test confirmation and at least the measuring device autonomous storage and / or transmission of data, whereby the logistical testing effort is reduced.

Preferably, the test confirmation is linked to a correspondingly matched measuring device for testing a system to form an autonomous overall system.

In an advantageous embodiment of the invention, the test confirmation means for the optical display of data. Preferably, the optical display is changeable, in particular not completely static. The test certificate is for this purpose, for example, equipped with a liquid crystal display on which in particular alphanumeric data and / or in particular graphics can be displayed. In particular, a large amount of data and / or visual information can thus also be displayed visually on a small area of a test confirmation, in particular a test badge.

For energy supply of elements of the test certificate, in particular a test sticker, this has a voltage supply in a variant of the invention. This is preferably realized with at least one battery or at least one battery. In a further embodiment, an additional power supply is provided with a solar cell module. This ensures in particular an extension of the battery life. In a further embodiment, a solar cell module preferably ensures a completely energy-autonomous energy supply.

Preferably, the power supply for elements of the test acknowledgment, such as e.g. the display module, activated only during an active use of the test confirmation by, for example, an examiner. Therefore, especially when using a non-volatile memory, for example, a permanent power supply of the test confirmation can be dispensed with.

Since an active use of the test confirmation by, for example, a tester is preferably carried out under normal daylight or comparable artificial lighting conditions, preferably a power supply by a solar cell module for powering the test confirmation is sufficient. If there is insufficient illumination, the power supply may have to be maintained by, for example, a battery, in particular for a time measurement.

According to another idea, the test acknowledgment comprises means for at least selection in a memory of the check confirmation data. In particular, this is a user interface. This has, for example, buttons for entering and selecting data, in particular for a menu control. For example, data stored in the test confirmation is then used by an examiner without assistance another device selected and visualized for example on a built-in optical display.

In a further refinement, a test confirmation separate from an elevator installation is preferably attached to a system to be tested during a first test. This is particularly advantageous in view of a useful variability, since similar copies of the test confirmation can preferably be used on a number of different systems. On a hydraulic elevator system, the test confirmation is attached, for example, to a surface of the car or, for example, to the control unit of the hydraulic system. On a hydraulic lifting machine, for example, quite different attachment points may be appropriate.

In another embodiment, a factory integration of a test confirmation in a system to be tested by, for example, a plant manufacturer to provide.

In order to avoid manipulation of a test certificate attached to a system, the test confirmation in a further embodiment is designed so that it is destroyed irreversibly when detached from a mounting surface. This is achieved, for example, by virtue of the fact that an adhesive force of a first part, for example a lower part of the test confirmation, on a mounting surface is higher than an adhesive force between the first part, for example the lower housing part, and a second part, for example a housing upper part, of the test confirmation. The housing is in this case preferably constructed so that the housing upper and lower housing part can not be separated indestructible, so that in particular in an attempt to replace the test certificate of the mounting surface, inevitably the upper housing part of the lower housing part is irreversibly released and thus the housing and thus the test certificate gets destroyed. The first and the second part may in particular be at least one foil in each case. For example, a film is a plastic film.

Preferably, the Prüfplakette is at least only at great expense without residue to remove from a mounting surface.

The attachment of the test certificate on a mounting surface takes place in an embodiment with mechanical fastening means, in particular non-positive and / or positive. For example, the attachment is effected by means of fastening straps and / or by means of screws and / or by means of riveted joints and / or by means of a clamping connection. In a further embodiment, the attachment of the test confirmation is carried out on a mounting surface by utilizing adhesive forces, for example by means of adhesive, soldering, bonding or welding connection. An adhesive bond is preferably carried out with a double-sided adhesive film. Optionally, it may also be a wet-applied adhesive film.

The invention is explained below by way of example with reference to the drawing in several embodiments. However, the features are not limited to the individual embodiments. Rather, features specified in the drawing and / or in each case in the description including the description of the figures can be combined to form further developments.

FIG. 1 shows an elevator installation 1 to be tested with a first test confirmation 2. The test confirmation 2 is here on a surface on a frame on a door of the elevator installation appropriate. But it can also be attached to other areas, both outside and inside, or be integrated into the manufacturer's own display areas.

For a better overview, the test confirmation 2 of Fig. 1 in Fig. 2 is shown individually enlarged. This test confirmation 2 contains a memory chip with integrated transponder 3. With the help of the transponder 3 data is received from a transmitter and can be stored in the integrated memory chip. In addition, the transponder allows a transmission of data in memory to an external receiving system. In this case, the transponder 3 is configured in particular in such a way that the energy required for operation is recorded at the time of a remote inquiry via an integrated antenna.
In addition, the test confirmation 2 contains a barcode memory 4, which is realized here with a graphic LCD display. At least part of data stored in the memory chip of the transponder 3 can be represented in the form of a bar code in this bar code memory 4.
The test certificate 2 shown is housed as a badge in a flat plastic housing, which is attached by means of a double-sided adhesive film to the elevator system 1.

FIG. 3 shows a schematic circuit configuration of a second test confirmation 5. The central component of the test confirmation 5 is a microprocessor 6 with a memory 7 connected thereto. The memory 7 is embodied here as a nonvolatile electronic memory.

Furthermore, the second test confirmation 5 contains a voltage supply 8. This is designed here in the form of a battery. Connected to the microprocessor 6 is an input / output scanning module 9 with integrated transmitting and receiving module. With the input / output scan module 9 data is read from the memory 7 and sent using the send / receive module to external receiver.

In particular, the input / output scan module 9 provides for an assignment of different data to different areas of the memory 7 provided for this purpose. In addition, it provides for the assignment of different data to different identification codes used in a transmission protocol for different data.

The shipping takes place with the integrated into the input / output scan module 9 transmitting and receiving module while on the one hand via a wired interface 10, which is, for example, a serial interface, and / or radio and / or infrared. The data reception from external stations takes place in the same way, in the opposite way. Data received with the transmitting / receiving unit are read into the memory 7 with the aid of the input / output scanning module 9.

For the representation of data located in particular in the memory 7, the second test confirmation 5 has a display 11, which is embodied here as an LCD display. This data is displayed in an alphanumeric format and / or in graphical form.
In order to provide a time-limited validity certificate with the second test confirmation 5, the test confirmation 5 is equipped with an electronic quartz clock module 12. This timing module 12 is connected to the microprocessor 6. Furthermore, in the connected to the microprocessor 6 memory 7 a maximum validity date can be stored. To check the validity of the second test confirmation 5, a time determined by the time measurement module 12 is continuously compared with a stored validity date. When the validity date is exceeded, a validity certificate, which is realized here with the aid of a display 11, is deactivated. In this case, the expiry of the validity certificate is indicated, for example, by a hint text on the display 11.

Figures 4, 5 and 6 show an embodiment of a non-destructive to be removed from the mounting surface 13 third test certificate 14. The third test certificate 14 is provided to achieve this property with a housing bottom 15 and an insert 16 comprehensive two-part Prüfbestätigungsunterseite.

In Fig. 4, the two-part embodiment is shown schematically from below. There, the housing bottom 15 can be seen with its insert 16. Contrary to the rectangular shape shown here, for example, round or irregular shapes of the insert are possible in other embodiments.

In Fig. 5, an associated central longitudinal cross-section is shown. The inner insert 16 is fixed here with a defined adhesive force in the housing bottom 15. The attachment is done for example by clamping with the aid of tabs, not shown here. For attachment to a partially shown here flat mounting surface 13 is a level underside of the third test certificate 14 with a likewise according to the two-part Prüfbestätigungsunterseite with a two-part double-sided adhesive film 17 equipped. The adhesive force of the adhesive film or the adhesive film 17 is dimensioned so that it is greater than the adhesive or clamping force of the insert 16 in the housing bottom 15 in any case.

FIG. 6 shows the third test confirmation 14 after an attempt to lift it off the mounting surface 13. Both housing bottom parts 15, 16 are separated from each other. As are also fixed according to electronic fittings 18 on the housing bottom parts 15, 16, parts of associated compounds 19 are irreparably destroyed, so that the third test confirmation 14 is rendered useless.

FIG. 7 shows a schematic plan view of a fourth test confirmation 20 on a flat attachment surface 21 shown in sections. The fourth test confirmation 20 is embodied here as a sticker. This includes a display 22, which is designed here as an LCD display. This is a representation of selected contents of a memory content in the form of alphanumeric characters and in the form of graphical representations. In particular, 22 different test parameters are displayed on the display. In order to be able to make a selection of data in the memory and to be able to carry out a display and menu control, the fourth test confirmation 20 furthermore has various pushbuttons 23, 24. With a menu key 23 and two selection keys 24, different menu items and selection levels can be selected ,

For power supply contains the fourth test certificate 20 in addition to a battery, not shown here, a solar cell module 25 for extending the battery life and / or even the autonomous power supply.

In addition to the above-described display 22, the fourth check confirmation 20 includes a bar code display 26 by means of which at least selected data can at least be read out with a bar code scanner. Preferably, standard EAN barcodes and the corresponding standard scanner technology will be used. Since the content of the bar code display 26 is changed several times in the course of a Prüfbestätigungslebensdauer, in particular after each successful testing of the associated system, this bar code display 26 is designed as a graphic LCD display.

In addition to the display 22, the fourth test certificate 20 includes another display unit 27. In this example, it is a lighting means, e.g. at least one light emitting diode, in particular an integrated from red to green switchable light emitting diode. This is used to visualize a validation certificate contained on the fourth verification certificate 20. When a validity date of the validity certificate expires, the LED is activated so that the color of the LED switches from green to red. However, it is also possible to use a plurality of light-emitting diodes or other light-emitting means, in particular different-colored ones.

According to a further idea, a mobile device, in particular a handheld device, serves to record or certify a test confirmation of an elevator installation with an electronically readable test confirmation. By way of example, the device comprises a portable computer equipped in particular with a transmitting and receiving device. The mobile device is preferably a handheld equipped in particular with a transmitting and receiving device.
