Title:
STATE ESTIMATION DEVICE AND COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2019140666
Kind Code:
A
Abstract:
To perform more detailed precursor detection of failures that occur in data transmission while reducing costs.SOLUTION: A state estimation device includes a preprocessing unit and an estimation unit. The preprocessing unit obtains data representing one or more of the phase, reception strength, reception quality, voltage after conversion to an electric signal, and signal processing parameters used in reception processing of a signal that is transmitted by a transmission unit of a transmission device and received by a reception unit of another transmission device via a transmission path, and processes the obtained data to feature data used for state estimation. The estimation unit estimates the state of the transmission path, the abnormal state of the transmission unit, or the abnormal state of the reception unit on the basis of the feature data.SELECTED DRAWING: Figure 1
