The device is used for utilizing the electric turntable 2 in cooperation with the three-axis mechanical arm 4 to drive the laser vibrometer 3 to align with the transmission line to be tested, so as to realize non-contact vibration measurement. A photovoltaic power generation component 6 and a wind power generation component 5 are also arranged at the top of the tracked inspection vehicle 1. The photovoltaic power generation component 6 and the wind power generation component 5 are both electrically connected to a battery component, and the battery component is electrically connected to the three-axis mechanical arm 4, the electric turntable 2 and the laser vibrometer 3, respectively.

[0022] The laser vibrometer 3 includes a laser transmitter and a receiver integrated on the housing. The laser receiver is electrically connected to a data acquisition and processor disposed inside the housing. The data acquisition and processor is used to extract vibration characteristics from the reflected laser signal using Doppler effect analysis or Fourier transform.

[0026] It should be noted that the above-mentioned electronic components are mature products on the market. This embodiment only needs to purchase them and connect them according to the instructions.
