Sensor network-based analysis and/or prediction method, and remote monitoring sensor device

A sensor-network-based analysis and/or prediction method for a protection from natural hazards, comprising at least method steps of:

• Providing an outdoor sensor network comprising sensor modules that are distributedly arranged, and which are fixed to ropes of one or more catchment and/or stabilization devices for rocks, stones, avalanches, debris flows or landslides, the sensor modules each comprising:
• acceleration sensors for a detection of impact sensor data in a form of accelerations occurring in an impact of an impact body in a respective catchment and/or stabilization device of the one or more catchment and/or stabilization devices, leading to commotions of the sensor modules of the respective catchment and/or stabilization device and/or
• rope force sensors for a detection of rope force sensor data in the form of rope pulling forces at ropes of a plurality of respective catchment and/or stabilization devices including the respective catchment and/or stabilization device,
• the sensor modules each further comprising:
• open-air corrosion sensors for a determination of outdoor corrosion measurement data in the form of a corrosivity of an outside atmosphere in an area of the respective catchment and/or stabilization device,
• Providing an external analysis and/or prediction unit, implemented separately from the sensor modules and implemented as a computer or a computer network, comprising at least one processor, at least one memory unit and at least one operation program that can be called up from the at least one memory unit by the at least one processor,
• Receiving and collecting outdoor corrosion measurement datasets with the outdoor corrosion measurement data and impact measurement datasets with the impact sensor data and/or rope force measurement datasets with the rope force sensor data from the sensor modules in the external analysis and/or prediction unit,
• Capturing geographic coordinates of the respective catchment and/or stabilization device or loading pre-captured geographic coordinates of the respective catchment and/or stabilization device,
• Receiving tropospheric measurement datasets and allocating the tropospheric measurement datasets which are received geographically to respective sensor modules of the sensor modules of the outdoor sensor network, wherein the tropospheric measurement datasets which are received comprise data allowing a deduction of at least one parameter of a troposphere surrounding a respective sensor module of the respective sensor modules,
• Geographically associating and allocating each of the outdoor corrosion measurement datasets which are received and each of the impact measurement datasets which are received and/or each of the rope force measurement datasets which are received with the geographic coordinates that are captured or loaded,
• Storing datasets of the outdoor sensor network including the outdoor corrosion measurement datasets, the impact measurement datasets, the rope force measurement datasets, and/or the tropospheric measurement datasets which are received in the at least one memory unit of the external analysis and/or prediction unit,
• Determining a natural hazard risk in the area of the one or more catchment and/or stabilization devices from an analysis of the datasets of the outdoor sensor network, wherein in the analysis of the datasets a pattern recognition is carried out by the external analysis and/or prediction unit using a significant time interval of all of the datasets that are received and the geographic coordinates of the respective sensor modules, wherein in the pattern recognition, progressions of the impact sensor data and/or the rope force sensor data of the datasets of individual sensors of the sensor modules of the outdoor sensor network and/or correlations of the progressions of the impact sensor data and/or the rope force sensor data of the datasets of a plurality of the individual sensors of the sensor modules of the outdoor sensor network are determined, resulting in a deduction of an augmentation or reduction of the natural hazard risk, and
• wherein on a basis of the pattern recognition a prediction of the natural hazard risk in the form of a probability of an occurrence of impacts into the respective catchment and/or stabilization device is determined by the external analysis and/or prediction unit, and
• Triggering a maintenance of the respective catchment and/or stabilization device, an immediate repair of the respective catchment and/or stabilization device or a deployment of a maintenance drone and/or a reconnaissance drone to the respective catchment and/or stabilization device depending on the prediction of the natural hazard risk that is determined by the external analysis and/or prediction unit.
