Abstract

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.

本发明涉及激光测振技术领域，公开了一种远距离激光铁塔螺栓测振系统及方法，其系统通过激光发射模块发射激光束并对焦至待测螺栓位置，通过激光接收模块接收反射回的激光信号，并将激光信号转换为电信号，确定信号强度偏差量，将信号强度偏差量发送至无人机导航模块，通过无人机导航模块根据信号强度偏差量调整无人机相对待测螺栓位置的距离和姿态，以确定无人机的喷涂位置，从而提高喷涂准确性，通过喷涂反光喷雾模块对待测螺栓位置进行喷涂反光喷雾，并通过测振模块在预设的测振条件下基于激光接收模块接收的电信号，确定螺栓位置的振动频谱数据，从而获得有效的反射信号，可以远距离进行测振，还提高了测振结果的准确性。
