Abstract
A data collecting device includes a receiver configured to receive an optical signal; an optical-to-electrical converter configured to convert the optical signal received by the receiver into an electrical signal; an analog-to-digital converter configured to convert the electrical signal into a digital signal; a data reducing circuit configured to reduce the digital signal output from the analog-to-digital converter; and a transmitter configured to transmit, to a managing device that manages the data collecting device, a signal obtained by reducing the digital signal by the data reducing circuit.
Claims10
A data collecting device comprising:
- a receiver configured to receive an optical signal;
- an optical-to-electrical converter configured to convert the optical signal received by the receiver into an electrical signal;
- an analog-to-digital converter configured to convert the electrical signal into a digital signal;
- a data reducing circuit having a neural network configured to map the digital signal to output-characteristic-amount data, the data reducing circuit configured to reduce the digital signal output from the analog-to-digital converter by discarding any of the output-characteristic-amount data within a predefined amount of normal-characteristic-amount data representing normal transmission of data through an optical network, and including a first characteristic-amount extracting circuit having a first reconfigurable-layered configuration with a first input layer, a first output layer including a first number of multi-input single-output units smaller than a second number of multi-input single-output units included in the first input layer, and a first hidden layer provided between the first input layer and the first output layer, the first hidden layer configured to map the digital signal output by the analog-to-digital converter to the output-characteristic-amount data provided for analysis and output, based on results of executing first machine learning on first coupling weight coefficients between the first input and first output layers;
- and
- a transmitter configured to transmit, to a managing device that manages the data collecting device, a signal obtained by reducing the digital signal by the data reducing circuit.
