VEHICLES IN MOTION WEIGHT MEASURING FIBER-OPTICAL DEVICE Russian patent published in 2018 - IPC G01G19/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the measuring equipment, and can be used to measure the vehicles in motion wheels and axles loading. Based on these measurements, the vehicle total weight can be calculated. Device comprises elastically deformable horizontally arranged plate, configured to receive the load by its upper surface as a result of the measured weight force action. Distributed sensitive element in the form of the optical fiber is rigidly connected to the elastically deformable horizontally arranged plate lower surface. Optical device is configured to measure the said optical fiber elongation as a result of the elastically deformable horizontally arranged plate bending deformation by the measured weight force application to its upper surface. Optical device is the optical range rangefinder, the lidar, configured to measure the time delay of radiation propagation along the said optical fiber proportional to the measured weight force applied to the elastically deformable horizontal plate upper surface. Optical fiber is rigidly connected to the elastically deformable horizontal plate lower surface by means of glue, and is located in the serpentine form.

EFFECT: observed in the claimed device implementation technical result is in enabling of the device reliability and durability due to the design simplification with simultaneous increase in the measurements accuracy.
