FTPS Track Long-wave Regularity Measuring Instrument
1. Measurement Principle and Application
The track long-wave regularity measuring instrument is a high-precision instrument that measures based on the photoelectric image principle, used for accurate measurement of various geometric parameters of railway tracks. This instrument integrates optics, mechanics, electronics and wireless network, adopts special light sources and CCD image sensors to perform high-precision detection of railway track geometry, and directly digitizes and displays parameters such as track elevation and track alignment. It provides reliable measurement data for track equipment maintenance, solves the problems of poor measurement accuracy and low efficiency of existing methods, and meets the requirements of "window maintenance" night operations for track maintenance and improves the quality of night operations.
This instrument can measure elevation and track alignment parameters within the 200m long-wave range. It provides reliable and effective data for track fine adjustment and maintenance, and is a powerful supplement to the absolute measurement of high-speed railway CPIII.
1. Conventional geometric parameter detection and construction operation guidance for railway track maintenance departments.
2. Review of track maintenance results after major track overhaul.
3. Detection of track defects after alarms from track inspection vehicles.
4. High-precision measurement of track lines on high-speed passenger dedicated lines.
2. System Composition and Measurement Principle
The system consists of a transmitting vehicle, a measuring vehicle and a feedback vehicle. The transmitting vehicle and the feedback vehicle are fixed at both ends of the section to be measured. The transmitting vehicle emits two collimated laser beams (transverse and longitudinal) and aligns with the feedback vehicle to form a reference. The measuring vehicle is pushed along the section to be measured, measures the displacement of the collimated laser beam through a high-precision CCD, and converts the displacement into various geometric parameters. The feedback vehicle monitors the jitter of the collimated laser beam in real time and transmits the jitter amount to the measuring vehicle in time for correction, eliminating the impact of laser jitter on the measurement results.
