Abstract

The invention relates to an electric power safety distance measurement alarm method based on a laser radar, and belongs to the technical field of laser radar distance measurement. The method comprises the following steps: S1, performing 360 DEG scanning by using a laser radar when a special vehicle is constructed in a high-pressure environment; S2, calculating a time difference between wave sending and wave receiving by using a phase method; S3, converting the echo signal into a pulse signal, and calculating pulse propagation time through a time measurement chip; S4, adjusting the distance measurement precision, and calculating the target distance; and S5, comparing the measured distance with an alarm threshold, and if the measured distance is smaller than the alarm threshold, giving an alarm. The method is high in distance measurement precision and good in alarm effect, and the risk of casualties caused by mistakenly touching the high-voltage line by the operation arm of the special vehicle is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of laser radar ranging, and relates to a laser radar-based power safety ranging alarm method. Background technique [0002] With the further improvement of the existing economic level, the demand for electricity is increasing day by day, which has led to an increasing number of electricity construction projects. Electric power construction safety management is an important item in electric power engineering. The safety management of electric power construction should be carried out under the perfect management system and scientific requirements of the whole electric power construction. [0003] Traditional photogrammetry methods require a variety of hardware and software such as high-definition cameras and image processing algorithms. At present, due to the limitations of databases and algorithms, there are large errors in size and distance measurement. It is also necessary to rely on methods such as visua...
