Description

 Maintenance system for an elevator installation

The invention relates to a maintenance system for an elevator installation, a method for the maintenance of a component of the elevator installation and such an elevator installation.

Traction systems include several components that wear out over time. In order to keep the elevator system functional for a long period of time, these components must be serviced or maintained by a service technician. The fact that maintenance of the component may be necessary can be recognized in many cases already by the service technician when he inspects the component.

Each individual elevator system is serviced by a service technician at regular intervals. Such maintenance comprises at least one work step to be performed on the component of the elevator installation, such as a status check, a function check, a lubrication, a cleaning, a repair and / or a replacement of this component. Which of these steps to take at a given time depends, among other things, on whether labor-intensive maintenance or less labor-intensive service maintenance is required. In addition, a recently occurred error message elevator system lead to a change in the maintenance of the component.

Accordingly, in a maintenance list associated with the elevator installation, it is already determined, prior to a maintenance to be carried out, which of the components of the elevator installation is to be maintained and which activities must be carried out on the individual component itself. This maintenance list is processed sequentially during the maintenance that takes place. This is followed by a confirmation of the performed maintenance, this confirmation is usually transmitted to a maintenance center. The problem with such a procedure is that the service technician can confirm that he has carried out the maintenance, but without ever having inspected the at least one component of the elevator installation to be serviced. Thus, under certain circumstances, this service technician does not recognize the actual necessity of carrying out a previously mentioned work step. Accordingly, it is an object of the invention to improve the quality of the maintenance of the elevator system.

The object is achieved by a method for the maintenance of at least one component of an elevator installation, wherein the component is provided with a marking and the marking enables an identification of this component, the method comprising the following method steps:

 Reading in the marking by means of a reading device,

 Listing of at least one work step necessary for the maintenance of the component by the reading device, wherein the work step to be listed is determined on the basis of data, which data can be taken from the marking,

 - Perform maintenance of the component, and

 - Entering a confirmation in the reader, by means of which the maintenance performed on the component is confirmed.

The object is also achieved by a maintenance system for an elevator installation comprising a component for the elevator installation, a marking arranged on the component, which marking permits identification of the component, a reading device for reading in the marking, which reading device is designed in such a way that by means of the marking removable data at least one necessary for the maintenance of the component operation by the reader is listable and that a confirmation of the maintenance performed in the reader can be entered.

The object is also achieved by an on zugsanlage with a component and arranged on the component marking, the mark allows identification of this component and readable by means of a reader and is designed such that based on the mark removable data at least one necessary step for Maintenance of the component by the reader is listable.

During the maintenance of an elevator installation, at least one component of this elevator installation can be serviced, which means that the maintenance of several components of the elevator installation can be synonymous with the maintenance of the elevator installation. The invention is based on the finding that only one process step of the entire maintenance process, with the exception of the at least one work step for the maintenance of the component itself must take place in the immediate vicinity of the component to be serviced or serviced, in order to draw the attention of the service technician to the required work steps. Accordingly, an attempt has been made to design the maintenance procedure in such a way that the service technician must be present in the immediate vicinity of the component in order to be able to confirm the performed maintenance.

This was achieved by marking the component. The marking can be arranged or fastened directly on the component or in preferably immediate surroundings of the component. By reading in this mark by means of the reader of the at least one step is stopped and the maintenance even on the reader only verifiable. This means that the maintenance of the component can not be considered as performed without a reading of the mark, because a confirmation of the performed maintenance is impossible. If appropriate, it is thus possible to determine the time span which the service technician has needed to maintain the component. Such a time span results from evaluation on the one hand of an assumed start time of the maintenance and on the other hand of an assumed end time of the maintenance. Such a start time can be set by the process of reading the mark by means of the reader. Such an end time may be set by the process of inputting the acknowledgment to the reader by which the maintenance performed on the component is confirmed.

In a development of the method, the marking is replaced by a secondary marking during the maintenance of the component. In this way, after performing the method, it can be detected directly by means of this secondary marking when this component has been serviced and possibly replaced. Likewise, such a replacement of the mark can be made for each maintenance of the component, for example, to be able to encode the information of the last time maintenance within the mark at the given time.

In a further development of the method, the input of the confirmation into the a reading in of the marking or the secondary marking. This means that the service technician reads in the mark both before carrying out the maintenance of the component and after the maintenance of the component. After the component has been serviced, the secondary marker can be read in instead of the marking due to a replacement of the marking by a secondary marker. This ensures that the service technician is also present at the end of the maintenance of the relevant component on this component.

In a development of the method, the confirmation of a control center for the administration of maintenance data of the elevator installation is transmitted. By means of such a central administration of the maintenance data, it is always possible to understand in what condition the elevator installation is located at the given time.

The marking or the secondary marking, as well as the identification of the component, can also enable the identification of the elevator installation. In addition, the marking may contain data in this way, which relate, for example, the time of installation of the elevator installation. Accordingly, it can be ensured that the confirmation of the performed maintenance can be uniquely assigned to a specific elevator installation. With regard to the confirmation of the maintenance thus confusion example. Are excluded with identical elevator systems. Likewise, it can be ascertained by means of a mark which can be assigned in this way which elevator installation is being serviced at the given time. By way of example, this is possible if, during the reading in of the marking by means of the reading device, information relating to the beginning of the maintenance is sent to a control center for managing the maintenance data.

The work steps necessary for the maintenance of the components can be stored in the reader. Alternatively, based on the identification of the component by means of the reader, the necessary steps for maintenance of a central office to the reader can be transmitted. This means that the reading of the mark causes the process of Übermitteins the necessary step to the reader.

Before reading the mark by means of the reader, the necessary steps for the maintenance of the component can be stored within the reader or in the center. For a prior storage of the maintenance data within the It is thus possible for every service technician to wait for the elevator installation to be serviced because he can call up this maintenance data at any time using the reading device available to him. In addition, it is therefore possible to understand the beginning of the maintenance of the component at the headquarters. For example, fault messages received prior to maintenance can influence the necessary maintenance procedure.

In a further development of the method, storage of ambient conditions of the component to be serviced, that is to say storage of ambient conditions of this component prior to maintenance of the same, is initiated by reading in the marking. In this way, detectable characteristics of the component can be recorded, ie stored. If necessary, based on this stored information malfunctions, which had this component prior to the subsequent maintenance and / or after the maintenance performed, be traced. On the basis of such stored information, it is therefore apparent in retrospect that a repair / replacement of this component was necessary.

In a further development of the method, storage of environmental conditions of the serviced component, that is to say storage of ambient conditions of this component after the maintenance thereof has been initiated, is initiated by reading in the marking or the secondary marking. In this way, detectable characteristics of the component can be recorded, ie stored. Since a check, which is usually declared during the maintenance of the component as a separate work step, may include a restoration of the full functionality of the component, it is subsequently comprehensible whether the test was dutifully carried out.

If such storage was initiated, ie also performed, prior to the maintenance to be carried out as well as after the maintenance has been performed, any malfunctions that may be present before the maintenance to be carried out can be identified which of the service technician's work steps have actually taken place.

The storage of environmental conditions can be exemplified by a photograph, by a few seconds after reading the mark / secondary mark be carried out vibration measurement by placing the reader on the component or by a sound recording. Such storage can be done by way of example when the component is operated in a service mode. For this purpose, it may be required that the reading device be held on the component a few seconds after reading the marking / secondary marking. Additionally or alternatively, by way of example, it may be required that the reading device be placed on the component a few seconds after reading the marking / secondary marking in order to detect said vibrations.

In a further development of the method, the reading of the marking by means of the reading device initiates an ordering process for the replacement of a component of the component to be serviced by means of a separate input into the reading device. Thus, a component considered to be defective may be ordered during maintenance.

In a further development of the method, the elevator installation has a first and a second component to be serviced, and it is determined by the input of the confirmation to the reader via a maintenance of the first component that the maintenance of the second component subsequently carries out this maintenance of the first component is. In this way, the service technician can be informed after interrupting the maintenance of the elevator installation by recording the last serviced component of this elevator system, which component of the elevator system is to be maintained next according to a predetermined sequence. This saves time.

In a further development of the method, parameters of the component determined during maintenance of the component are stored in the reading device. These parameters can thus be stored and thus retrieved in future maintenance of the component, so that this stored parameter during future maintenance can be compared with a current during the future maintenance parameters. In this way, conclusions about the wear of the component can be determined.

The marker may be formed, for example, as a dot or square or bar code or as an AFID transponder or color pattern. Depending on the one to be serviced Component, the label may therefore be selected such that environmental conditions, such as increased risk of contamination around the mark, have no significant influence. In the following the invention will be explained in more detail with reference to figures. Show it:

FIG. 3 shows a reading device 22, which is arranged on the car door 12 for reading in a marking 20 associated with the car door 12 of the elevator car 4. Such a mark 20 associated with the car door 12 may preferably be arranged on a door wing or a transom of the car door 12. Thus, a service technician can read the mark 20 by means of the reader 22 from a floor 14, when the elevator car 4 in a corresponding position for the maintenance of Cabin door 12 is arranged in the elevator shaft. The maintenance of the car door 12 may include replacing, inspecting or repairing various components of the car door 12, such as the door latch, the door operator, door guide, guide shoes for guiding the door leaves of the car door in the car door sill, and or door contacts.

The reading device 22 can be connected by means of a wireless communication network with a central office 24 for managing maintenance data of the elevator installation or maintenance data of the example embodied as a car door 12 component. During maintenance of the component 12, the marking 20 is read in by means of the reading device 22. Initiated by this reading by means of the reader 22, a storage of the ambient conditions of the cabin door 12 can be made. This may be a photograph on which, where appropriate, operational destruction of the car door 12 can be seen, for example, door wings deformed by elevator passengers or cables of a car door control scored by short circuits. In the case of an existing connection between the reading device 22 and the center 24, on the basis of the data contained in the marking 20, at least one necessary work step for the maintenance of the component 12 is selected and transmitted from the center 24 to the reading device 22. Data coded in the marking 20 thus lead to at least one work step being selected from a plurality of possible work steps for the maintenance of this component 12. On the basis of the data contained in the marking 20, this means, for example, that data stored in a database and assignable to this component 12 are accessed. Such a database may be stored in the central office 24 or in the reader 22 itself.

This operation is indicated by the reader 22 so that the service technician receives the information necessary for maintenance. For example, the data coded in the marking 20, for example with regard to the time of installation of the elevator installation, which elevator installation comprises the component 12 to be serviced, can lead to lists of work steps to be performed during maintenance as a function of this time.

Subsequently, the listed steps for the maintenance of the component 12 are performed. After the maintenance of the component 12 is confirmed by means of an input to the reader 22 that these steps were performed. Similar to the prior to the maintenance of the component 12 of the acceptable storage of the environmental conditions can be initiated by this confirmation, a storage of the environmental conditions are made.
