Device for determining the actual state and/or the remaining service life of a construction, materials-handling and/or conveyor machine

A device for determining the actual state and/or the remaining service life of a construction, materials-handling and/or conveyor machine, the device comprising:

• a plurality of sensors on the construction, materials-handling and/or conveyor machine for recording various state information, wherein the plurality of sensors are integrated in an interior of a transmission of the construction, materials-handling and/or conveyor machine, wherein the plurality of sensors comprises various sensor types for recording at least two different categories of information from the group comprising component oscillations, lubricant properties, component and/or lubricant temperature and drive loading, wherein the plurality of sensors comprises an oscillation sensor for detecting component oscillations and at least one of the following sensors:
• an oil particle sensor, an oil viscosity sensor, an oil conductivity sensor for detecting transmission oil particles and/or transmission oil condition,
• a recording unit connected to the plurality of sensors for gathering recorded state information,
• a central unit connectable to the recording unit for evaluating gathered state information and for determining the actual state and/or the remaining service life from the gathered state information, wherein the actual state and/or the remaining service life is determinable by the central unit based on the at least two different categories of information, and
• a display device for displaying the actual state determined by the central unit and/or the remaining service life determined by the central unit,
• wherein the display device is provided on the construction, materials-handling and/or conveyor machine and is configured to display gathered state information and the actual state and/or the remaining service life to a control station,
• wherein the display device is configured to be touch-sensitive as a touch screen,
• wherein the display device comprises a control device of the control station such that upon touching an area of the display device in which a specific machine component of the construction, materials-handling and/or conveyor machine is displayed, the control device is configured to reconfigure the display device,
• wherein the central unit comprises a weighting device for differentially weighting different gathered state information and/or different information derived therefrom,
• wherein the actual state and/or the remaining service life is determinable by the central unit based on weightings of the different gathered state information and/or the different information derived therefrom,
• wherein the weighting device is configured to give a different weighting to an oscillation signal of the oscillation sensor and/or an oscillation characteristic value derived therefrom than to a temperature value of a temperature sensor and/or a temperature characteristic value derived therefrom, and/or is configured to give a different weighting to speed and/or torque information of a speed and/or torque sensor and/or a speed and/or torque characteristic value derived therefrom than to oil condition information of the oil particle sensor,
• wherein if a recorded state information item exceeds a predetermined threshold value, but all other state information items are below their respective threshold values, the central unit regards the exceeding of the predetermined threshold value as unproblematic, and if three recorded state information items are beyond their respective threshold values, a maintenance signal is triggerable via the central unit.
