1.The track inspection instrument is a cutting-edge device designed to meticulously assess track geometry status. Utilizing the advanced precise angular measurement principle of fiber optic gyroscope trajectory measurement, it is equipped with a rugged notebook computer tailored for field operations, acting as the data processing hub of the entire system. This enables real-time data and waveform display, coupled with the capacity to immediately alert for any over-limit conditions across all inspection items. zmwm14
