The invention relates to the technical field of laser vibration measurement, and discloses a long-distance laser tower bolt vibration measurement system and method, and the system transmits a laser beam through a laser transmitting module, focuses the laser beam to the position of a to-be-measured bolt, receives a reflected laser signal through a laser receiving module, converts the laser signal into an electric signal, determines the signal intensity deviation value, and carries out the measurement of the to-be-measured bolt. The signal intensity deviation value is sent to an unmanned aerial vehicle navigation module, and the unmanned aerial vehicle navigation module adjusts the distance and posture of the unmanned aerial vehicle relative to the position of the bolt to be measured according to the signal intensity deviation value to determine the spraying position of the unmanned aerial vehicle, so that the spraying accuracy is improved; reflective spray is sprayed to the position of a to-be-measured bolt through the reflective spray spraying module, and vibration spectrum data of the position of the bolt is determined through the vibration measurement module on the basis of an electric signal received by the laser receiving module under a preset vibration measurement condition, so that an effective reflected signal is obtained, vibration measurement can be performed remotely, and the measurement accuracy is improved. And the accuracy of a vibration measurement result is also improved.
