Description

[0001] The invention relates to a device for warning of a functional impairment, of impending damage and / or damage to bearings for guiding components that move relative to one another, for monitoring the function of the bearings and for providing information for carrying out maintenance of the bearings, wherein the bearings each have at least one sensor device connected to a transceiver for monitoring the function of the respective bearing and the transceiver is connected to at least one data processing system via a modem and a data network.

[0002] The document DE 10 2019 005 703 A1 discloses a device for testing and monitoring the function of a rolling bearing cage for holding and guiding rolling elements of a rolling bearing. Devices for testing and monitoring the function of a rolling bearing cage for holding and guiding rolling elements of a rolling bearing are characterized in particular by the fact that the function of the rolling bearing cage can be easily monitored, especially during operation of the rolling bearing. For this purpose, the rolling bearing cage has at least one sensor device with at least one acceleration sensor and / or at least one sound transducer and / or at least one temperature sensor. The sensor device is connected to a data processing system, which is further connected to a transmitter or transceiver of electromagnetic waves and / or at least one data network.

[0003] An instrumented bearing and a manufacturing method for such an instrumented bearing are known from DE 10 2015 103 408 A1. The bearing is equipped with a measuring device for measuring at least one functional parameter of the bearing. The measuring device comprises a sensor and a wireless transmitter. The sensor is designed to measure a characteristic value of the bearing's function. The characteristic value can be a temperature, a speed, an acceleration, a lubrication level, a vibration, or an acoustic amplitude.

[0004] The invention defined in claim 1 is based on the object of easily checking the function of bearings and providing information about their maintenance.

[0005] This problem is solved by the features listed in claim 1.

[0006] The device for warning of a functional impairment, of impending damage and / or damage to bearings for guiding components that move relative to one another, for monitoring the function of the bearings and for providing information for carrying out maintenance of the bearings, wherein the bearings each have at least one sensor device connected to a transceiver for monitoring the function of the respective bearing and the transceiver is connected to at least one data processing system via a modem and a data network, is characterized in particular in that the function of the bearings and their maintenance can be easily checked.

[0007] For this purpose, the data processing system - a data input and output module connected to the modem for data input, data output and starting the query of the data from the sensor devices of the bearings, - a test module connected to the data input and output module in conjunction with a memory containing arrays of data assigned to the warehouses to check the respective array for the presence and completeness of the data assigned to the warehouses and in conjunction with a creation module to create a new array with the data of a new warehouse, - a data processing module connected to the test module for comparing the data sent via the transceiver, the modem and the data network from the sensor devices of the bearings with the data of the arrays associated with the bearings and for determining the difference between the sent data and the data of the array of each of the bearings, - an evaluation module connected to the data processing module for evaluating the individual data, the comparison of the data and / or the differences determined, which is further connected to the data input and data output module and is designed such that the individual data, the comparison of the data and / or the differences determined are assigned to the respective warehouse and the evaluation is output via the data input and data output module.

[0008] The arrays have indices. The creation module is connected to the data input and output module to create a new array containing the data of a new warehouse. The new array is assigned an index plus one relative to the integer indices of the arrays in memory and stored in memory in conjunction with the memory. Furthermore, the evaluation module is connected to the data input and output module and is configured to assign the individual data, the data comparison, and / or the determined differences to the respective warehouse.

[0009] Using this device, the function of the bearings can be easily checked. Furthermore, information about their maintenance can be retrieved and thus obtained. The basis for this are the arrays, each of which contains the data for a bearing. An array is a data structure for storing and organizing data. The data is arranged and linked in a specific way. This enables efficient access to the data and its management. The data acquired by the sensor devices is compared with the data in the arrays and evaluated. The evaluations are assigned to the respective array as data, although changes to the data can also occur. The evaluations can be based on operating values ​​and limit values ​​that determine the properties of the bearings, as well as on the relationships between them. The operating values, limit values, and their relationships are the components of the respective arrays.The relationships can be represented by formulas and thus by their relationships alone or in combination. This allows for easy monitoring of the bearings, with warnings issued in the event of or before functional impairment, impending failure, and / or damage. The warning can be issued automatically via the data input and output module and via a connected network to a connected external data processing system. The warning can also be issued when data is missing from arrays.

[0010] The facility is also characterized by the fact that the array of a new warehouse is automatically checked. If the result is positive, the array is assigned to the facility. If the result is negative, a notification is sent via the data input and output module so that any necessary corrections and / or additions to the data of the respective array can be made.

[0011] The device, which warns of functional impairment, impending damage, and / or failure of bearings used to guide components that move relative to each other, monitors their function, and provides information on how to carry out maintenance, is particularly suitable for systems or clusters of systems each with at least one bearing. Such clusters of systems include, for example, wind farms.

[0012] Advantageous refinements of the invention are set forth in the following developments and embodiments. These can develop the device for warning of functional impairment, impending damage, and / or damage to bearings for guiding components that move relative to one another, for monitoring their function, and for providing information for performing their maintenance, individually or in combination. The bearings each have at least one sensor device connected to a transceiver for monitoring the function of the respective bearing, and the transceiver is connected to at least one data processing system via a modem and a data network.

[0013] In a further development, the creation module may comprise a module for transmitting the detection of a new warehouse and / or at least one array with incomplete or incorrect data, which module is connected to the data input and data output module.

[0014] In a further development, the creation module may comprise a module for receiving data about the new warehouse for creating a new array and / or for correcting the array with the incomplete or incorrect data, which module is connected to the data input and data output module.

[0015] In a further development, the creation module may include a module for checking the new array for completeness of the data and / or for checking the data of the corrected array.

[0016] In one embodiment, the sensor devices of the bearings can each have at least one temperature sensor and / or at least one acceleration sensor and / or at least one sound transducer.

[0017] In one embodiment, the temperature sensor can be an NTC thermistor combined with a pull-up resistor. The NTC thermistor is a temperature-dependent resistor with a negative temperature coefficient of electrical resistance—a thermistor, where NTC stands for Negative Temperature Coefficient Thermistor. The pull-up resistor ensures a clearly defined signal.

[0018] In one embodiment, the arrays may advantageously include data on the locations of the bearings and operating parameters of the bearings.

[0019] In one embodiment, the arrays may have limit values ​​of at least one physical property of the bearings that can be detected by the sensor devices.

[0020] In one embodiment, the transceiver and the sensor devices can be connected to a further data processing system, wherein the transceiver and the further data processing system are components of an electronic assembly. Furthermore, the further data processing system is configured such that time-related measured values ​​are assigned to the arrays as data following measurements of the physical properties of the bearings detected by the sensor devices.
