    摘要： A remote computing system is described that includes at least one processor and at least one module. The at least one module is operable by the at least one processor to receive first operational data collected by a first line-replaceable-unit of a first aircraft during flight operations of the first aircraft, and receive second operational data collected by at least one second line-replaceable-unit of at least one second aircraft during flight operations of the at least one second aircraft. The at least one module is further operable by the at least one processor to predict, based at least in part on the first operational data and the second operational data, a failure condition associated with the first line-replaceable-unit of the first aircraft, and output, based on the impending failure condition, an indication of the predicted failure condition.

    摘要： The invention relates to a method for automatically monitoring at least one component of a physical system; wherein at least one sensor of the component outputs an electrical signal via a measuring chain, said signal being read and processed and saved in a file as data in a data set; wherein the data of the data set are then checked in a first checking step for errors that could have been caused by a prior processing of the data; wherein the data of the data set are then brought into the physical context of the at least one sensor in a second checking step and checked for errors that could have been caused by damage to the reception of the physical and/or system-related conditions of the elements of the measuring chain; wherein the data of the data set can then optionally (if a plurality of sensors are present, if said sensors are to be considered equivalent due to the system, such as due to close proximity on or in the monitored physical system) checked in the context of the equivalent neighbors thereof in a third checking step for errors that could arise from damage to the conditions of similarity and/or dependency; wherein the data of the data are then brought into the context of the component in a third or fourth checking step and checked for errors that could arise from damage to the physical and/or system-related conditions of the component; and wherein the individual errors indicated are then checked against each other in a fourth or fifth checking step and either rejected or output as an error message with reference to the source of the error.

    摘要： An operation control apparatus includes a command generation portion that generates a command signal for commanding operation of a control surface, and first and second monitoring portions that monitor an abnormality of operation of first and second control portions, respectively, of the actuator control apparatus. The actuator control apparatus includes first and second control portions that generate a control signal for an actuator for driving the control surface and that are different in design, and a switching unit that switches the connection to the actuator from one of the first and second control portions to the other, when an abnormality is detected by the first and second monitoring portions. Accordingly, it is possible to monitor a generic failure, and realize redundancy enabling control of the overall operation of the actuator, from start to finish, when a generic failure has occurred, thus realizing further simplification and streamlining of the configuration.

    摘要： A storage unit stores a first reference value of an input/output electric signal into/from control unit and a second reference value of an input/output electric signal into/from a monitoring unit. If the amount of deviation between the input/output electric signal into/from the control unit and the first reference value exceeds a threshold value, a first caution signal output unit detects degradation of the control unit and outputs a caution signal. If the amount of deviation between the input/output electric signal into/from the monitoring unit and the second reference value exceeds a threshold value, a second caution signal output unit detects degradation of the monitoring unit and outputs a caution signal. The first and second reference values are acquired and stored in the storage unit in a period between completion of production of the control unit and the monitoring unit and start of the operation thereof.

    摘要： By the invention one or more bolt gauges (6) each with a built-in load cell (LC, not shown) are positioned on a blade bolt or a bearing bolt between a pitch bearing and a nut and tensioned by the nut at the inside or the outside of a hub of a wind turbine. The bolt gauge then outputs a signal descending both from the tension from the bolt/nut connection and the tension from the blade when the blade is vibrated due to wind forces and the rotation of the blade when the hub of the wind turbine is rotating. Further a severe and alarming change in each blade frequency is monitored as each blade frequency is compared to the other blade frequencies and an alarm is set and/or the wind turbine is stopped if a given level is reached.
