Transmission optical cable real-time alarm method and device based on deep learning algorithm

The invention discloses a transmission optical cable real-time alarm method and device based on a deep learning algorithm. The method comprises the steps of constructing an optical cable spatio-temporal data set of a transmission optical cable; performing spatio-temporal feature extraction on the optical cable spatio-temporal data set; performing vibration data prediction by using a long short-term memory network to obtain a vibration data prediction value; and comparing the obtained vibration data prediction value with a preset vibration data threshold value, and sending out an alarm signal when the vibration data prediction value is greater than the vibration data threshold value. According to the invention, the accuracy of vibration data prediction is improved, the condition monitoring of the transmission optical cable can be carried out more reliably, and the real-time alarm function of the transmission optical cable can be realized more accurately, so that a worker can take prevention or remedial measure
