Figure 7 shows a graph with 15 point RMS values for humans. It can be seen that the energy level of most signals taken for humans is between 0.24 and 0.37. After that, it comes Electronics 2021, 10, 3094 9 of down. After the rise, the energy level declines continuously. This plot shows the model of a human gait. Figure 8. 15 Point RMS values of 6 event signals of elephants. Figure 8 shows a graphic of the 15 point RMS values for elephants. The energy level of most of the signals taken for the elephant can be observed to be between 0.07 and After that, energy level goes up. After passing the power level of the fiber optic cable, the signal goes down again and its range is 0.06 to 0.11. Figure 9. 15 Point RMS values of 6 event signals of tigers. Figure 9 shows a graph of RMS values of 15 dots for tigers. One can observe that the energy level of the signal increases when the tiger approaches the optical fiber sensor. The signal features a small rise at the beginning and then a sudden rise, after that it goes down, then a small rise and fall until the end. The pads of the tiger foot are very soft, so it applies Electronics 2021, 10, 3094 10 of a very small amount of pressure to the fiber cable—that is why the RMS energy level of signature varies from 0 to 0.13 Figures 10 – 12 shows the signal for the motion of several people over a buried fiber cable. The observation of the magnitude increase for walking, running, tapping performed across the cables is illustrated in Table 3 Download 2.4 Mb. Share with your friends:
