Definitions
- the present invention relates to a method and an elevator control arrangement for controlling a maintenance mode of an elevator installation.
- Elevator systems are usually used for the vertical transportation of people and / or goods within buildings. As a rule, an elevator car is relocated within an elevator shaft.
- Elevator shaft pit In addition, during the maintenance mode, options for how the elevator car may be moved within the elevator shaft may be limited, for example to protect the technician from a collision with the elevator car.
- Elevator shaft of the elevator system is located. Furthermore, the machine-detectable feature of the elevator system is uniquely assigned.
- the method further comprises receiving the maintenance termination signal by an elevator control that controls the maintenance mode and then, preferably automatically, the elevator control
- Elevator control generated exit the maintenance mode.
- an elevator control arrangement for controlling a maintenance mode in an elevator installation is proposed.
- Maintenance mode controlling elevator control is configured to end maintenance mode upon receipt of the maintenance completion signal.
- a computer-readable medium which corresponds to a computer program product stored thereon one embodiment of the third aspect of the invention.
- the aim is to be able to end a maintenance mode in which an elevator system is located while maintenance work is being carried out in such a way that certain legal or other regulations are met on the one hand and none or only one on the other little additional hardware is to be operated.
- This is intended on the one hand to ensure that the maintenance mode can only be ended when predetermined safety conditions within the elevator installation have been met, i.e. for example all elevator doors and possibly one door to one
- Elevator pit are closed, and when the maintenance technician is outside the elevator shaft. On the other hand, the maintenance mode of the
- Maintenance technicians can be ended in a simple manner and yet safely and reliably. As little or no additional hardware as possible should be required.
- structural precautions that have to be taken in order to be able to end the maintenance mode in the desired manner, if possible, the visual appearance of the elevator system, i.e. their design, do not disturb.
- the portable computer-controlled device can be, for example, a smartphone, notebook, notepad or the like.
- the device should be sufficiently small to be portable, ie in order to be able to be carried by the technician without excessive effort.
- the portable device should be, for example Have a weight of less than 5 kg, preferably less than 0.5 kg.
- the portable device should be computer-controlled, ie at least have a processor and, as a rule, also have a data memory so that signals can be processed and buffered.
- the portable computer-controlled device can be used by the technician for a variety of purposes, for example for telephoning, as a planner, as a camera, etc. Accordingly, the
- the portable device can insert information about its environment and / or output information or signals to other devices.
- Such interfaces can be implemented in the form of sensors that can be used to record environmental conditions.
- a magnetic field sensor can detect a magnetic field in the area of the portable device.
- a camera can capture an optical image of the surroundings of the portable device.
- One or more of the interfaces can also be designed as data communication paths via which data or signals can be exchanged with other devices.
- Data communication paths can be wired or wireless.
- the data communication paths can be implemented in the form of a radio connection, in particular a WLAN or Bluetooth connection.
- the machine-detectable feature can, as specified in more detail below, be technically implemented in different ways. In any case, it should be realized in such a way that it can be recognized automatically by the portable, computer-controlled device of the technician, ie, for example, without the technician having to do anything, as soon as the device comes close to the machine-detectable feature in a predeterminable spatial constellation.
- the portable computer-controlled device When the portable computer-controlled device has generated and issued the maintenance termination signal, it can be sent to the elevator control, which controls the maintenance mode within the elevator installation. When the elevator control receives this maintenance completion signal, it can then exit the maintenance mode of the elevator installation. The elevator system can then return to its normal operating mode. Overall, the maintenance termination signal can thus only be generated and the maintenance mode of the elevator system can then be ended if the technician carries a portable computer-controlled device with it, which is suitably configured to recognize the machine-detectable feature of the elevator system and then to generate the maintenance termination signal, and if the technician is also outside the elevator shaft and in sufficient proximity to the machine detectable feature.
- Outputs maintenance termination signal upon receipt of which the elevator control then ends the maintenance mode.
- Authorization can take place, for example, in that the user has to enter a personal identification number (PIN) known only to him or another type of authentication is required. This can ensure that the portable computer-controlled device is not used by anyone other than the maintenance technician authorized to do so to end the maintenance mode of the elevator system.
- PIN personal identification number
- the RFID transponder can passively or actively return a radio wave signal emitted by a reader if the reader comes sufficiently close to the RFID transponder.
- the radio wave signal can be modified in a predetermined manner so that the reader can infer the existence of the RFID transponder when it receives the returned signal. If necessary, further information can be transmitted with the reflected signal, which allows the reader to recognize the identity of the RFID transponder.
- the RFID transponder can optionally be made very small and thus space-saving and can be kept in the elevator system.
- the RFID transponder can be implemented in the form of a circuit applied to a film or another substrate. In particular, the RFID transponder can, for example, be kept at a hidden location or also behind a panel or an overlying layer, so that it is visual
- the technician's portable computer-controlled device can have a suitable sensor system in order to be able to act as a reading device for the RFID transponder and to be able to process the information read out from the RFID transponder.
- the portable computer-controlled device can also use the information returned by the RFID transponder to infer the identity of the elevator system, provided that an RFID transponder uniquely assigned to it is available for each elevator system.
- the machine-detectable feature is identified by an optically recognizable one clearly assigned to the elevator installation
- the portable computer-controlled device recognizes the machine-detectable feature by optically recognizing the optically recognizable feature arrangement.
- the machine detectable feature can be in the form of a
- Feature arrangement are kept in the elevator system, which can be optically recognized.
- the feature arrangement can be formed by various visually distinguishable measures.
- Sample page can be optically
- perceptible objects in the elevator installation are set up in a certain relation to each other and / or their surfaces can have optically perceptible properties such as colors, patterns, etc.
- Image analysis can be recognized.
- the optically recognizable image analysis can be recognized.
- the optically recognizable image analysis can be recognized.
- Feature arrangement should preferably be integrated into a design of the elevator installation in such a way that it is perceived as part of this design and is not perceived as disturbing.
- the optically recognizable feature arrangement can be selected in such a way that it can only be recognized by the portable computer-controlled device when it is located at a predetermined position outside the elevator shaft.
- the optically recognizable feature arrangement can be recognized, for example, by taking and then analyzing a photo of an environment of the elevator shaft by the portable computer-controlled device.
- the portable computer-controlled device can be any portable computer-controlled device. According to one embodiment, the portable computer-controlled device can be any portable computer-controlled device.
- Data cloud can then send another maintenance completion signal to the
- Elevator control can be issued.
- the portable computer-controlled device can do more than that
- information about the identity of the elevator system can be contained in an optically recognizable feature arrangement in an elevator system, which e.g. can be extracted by image analysis.
- the portable computer-controlled device Upon receipt of the RFID signal or through an image analysis of a recording of the optically recognizable feature arrangement, the portable computer-controlled device can thus deduce the identity of the elevator system concerned and a corresponding identification signal together with the
- the portable computer-controlled device can output the maintenance termination signal directly to the elevator control.
- the portable computer-controlled device can exchange signals or data directly with the elevator control, preferably via an interface.
- Interface can be wired or wireless.
- a radio network generated in a building can be used to let the portable computer-controlled device communicate with the elevator control.
- the portable computer-controlled device can communicate with several different elevator controls, it can be used here that the machine-detectable feature is uniquely assigned to the elevator system concerned, so that a suitable analysis of this feature can be used to determine which of the elevator controls the portable computer-controlled device should communicate with and on this should transmit the maintenance completion signal.
- a maintenance mode can be ended by performing a method according to the invention in the elevator control arrangement.
- FIG. 1 shows an elevator system 1 with an elevator control arrangement 3, by means of which a maintenance mode of the elevator system 1 can be ended in a targeted manner, according to an embodiment of the present invention.
- a technician 13 can previously set a maintenance mode in the elevator installation 1, so that the
- Elevator system 1 on the one hand, can no longer be used by passengers and, on the other hand, technician 13 can control the movements of an elevator car in elevator system 1 while he is, for example, inside an elevator shaft 15.
