Abstract

A device for outputting a future state of a central lubrication system includes at least one sensor for recording a parameter of the central lubrication system, a processing unit for processing the recorded parameter, determining a current state of the central lubrication system based on the processed parameter, and estimating a future state of the central lubrication system over a certain period of time based on the current state and stored data, and an output unit for outputting the future state of the central lubrication system.

First claim

What is claimed is:

1 . A device for outputting a future state of a central lubrication system, including:
at least one sensor for recording a parameter of the central lubrication system, a processing unit for processing the recorded parameter, determining a current state of the central lubrication system based on the processed parameter, and estimating of a future state of the central lubrication system over a certain period of time based on the current state and stored data, and an output unit for outputting the future state of the central lubrication system.

2 . The device according to claim 1 , wherein:
the at least one sensor is configured to record at least two parameters, and wherein the processing unit is configured to estimate the future state of the central lubrication system based on a combination of the at least two parameters.

3 . The device according to claim 1 , wherein the future state indicates a failure probability of the central lubrication system and/or a maintenance timing of the central lubrication system.

4 . The device according to claim 1 , wherein the current state of the central lubrication system indicates a fault of the central lubrication system, and wherein the processing unit is configured to determine a position of the fault.

5 . The device according to claim 4 , wherein the output unit is configured to output the current state of the central lubrication system and the position of the fault.

6 . The device according to claim 1 , wherein the sensor is a temperature sensor, a fill-level sensor, a pressure sensor, a flow sensor, a contamination sensor, and/or a lubricant-detection sensor.

7 . The device according to claim 1 , wherein the stored data are historical data.

8 . The device according to claim 1 , wherein the output unit is configured to transmit the current and/or the future state to a storage device.

9 . The device according to claim 8 , wherein the storage device is an external storage device and the output unit is configured to communicate with the storage device via a communication connection.

10 . The device according to claim 9 , wherein the communication connection is a radio connection.

11 . The device according to claim 2 ,
wherein the future state indicates a failure probability of the central lubrication system and/or a maintenance timing of the central lubrication system, wherein the current state of the central lubrication system indicates a fault of the central lubrication system, and the processing unit is configured to determine a position of the fault, wherein the output unit is configured to output the future and/or current state of the central lubrication system and the position of the fault to a storage device, wherein the sensor is a temperature sensor, a fill-level sensor, a pressure sensor, a flow sensor, a contamination sensor, and/or a lubricant-detection sensor, and wherein the stored data are historical data.
