Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples, but the examples should not be construed as limiting the present invention.
[0017] see Figure 1 to Figure 2 , the distributed ice-melting monitoring method of the transmission line of the present invention comprises the following steps:
[0018] Step 1. Use the Brillouin Optical Time Domain Reflectometer to monitor the monitoring data F(x i ,t m );
[0019] Step 2: Analyze and process according to the monitoring signal, and extract the pre-processed signal data F in real time m (x i ,t m );
[0020] Step 3. Set the initial center P of the data set i , for density classification;
[0021] Step 4. Classify the results according to the density {R 1 , R 2}, to distinguish the meaning of the signal representation at this time;
[0022] Step 5: Eliminate abnormal points or isolated points, and determine whether the ice melting or deicing is...
