SOKOL-2 high-speed system for track geometry assessment
SOKOL-2 track geometry assessment system is mounted on the bogie frame of any vehicle and intended for high-speed measurement of rail track geometry and rail head profiles with a contactless method at speeds up to 250 km/h.
Part number:
Supplier:
JSC "Firma TVEMA"Description
Precise measurement data acquisition is given due to the combination of two techniques, optical triangulation and inertial techniques.
Optical triangulation with an illuminating laser and receiving video cameras is applied for the contactless measurement of the position and geometry of both rails. Inertial techniques in form of an IMU (inertial measurement unit) provide real time calculation of the required characteristics of motion and orientation parameters in space.
Optionally, SOKOL-2 can host such additional equipment as video recorder and riding comfort monitoring systems for inspecting the effect of changes in rail profile and track gauge geometry on train travel parameters.
All acquired information is processed in real time, logged and documented for further analysis and for scheduling work in current maintenance and repair of the track.
SOKOL-2 software can reference the information on actual rail condition to the information retrieved from the database for the particular track section. It automatically compares the parameters obtained with the required parameters, and generates reports and recommendations for operating and managing divisions of railways.
The data acquired during travel is transmitted to the onboard computer system, which provides the visualization and logging of rail track geometry and its deviations from maintenance standards, as well as the required restrictions of travel speed. Moreover, all deviations are analysed in quantity and quality and are referenced to particular coordinates.
