| Summary: | This paper discusses a new method for measuring and calculating the angle of
inclination of a railway support or a contact network support, using an unmanned
aerial vehicle flying along a straight path, parallel to the railway track. A review of
existing measurement methods is carried out, their advantages and disadvantages
are indicated. In the method under consideration, it is proposed to measure angles
and distances with six laser scanning rangefinders installed in threes on horizontal
and inclined planes on an unmanned aerial vehicle. This allows you to increase the
speed and accuracy of determining the angle of inclination of vertical supports. The
calculations use the minimum distances from the laser scanning range finder to the
top and bottom of the support surface. The formulas use geometric relationships and
the cosine theorem to calculate the roll of supports taking into account their taper.
Measuring distances and angles three times allows for averaging over them, which
significantly increases the accuracy of calculations. A model experiment is carried out
on a model of a reinforced concrete contact network support in four orientations. A
comparison is made between theoretically calculated and experimentally measured
distances and inclination angles. The accuracy of parameter determination complies
with regulatory requirements. |
