The Research for Precision Measuring Technology of High Speed Turnout Based on the Least Square Method

Along with the increase of high-speed railway construction projects, the impact of high -speed railway turnout related technology on railway construction is more and more prominent, high speed turnout ride requirements are also getting higher and high-er. Aiming at the problem of direct influence on the train running speed, comfort and safety, the research scheme of high speed turn-out precision measurement is put forward. Using the least square fitting algorithm for trend line analysis, at the same time looking for waiting to adjust the interval, extracting data. comparing the experimental results, verify the turnout fine measuring technical feasibili-ty. Turnout fine adjustment experiment results show that least square fitting algorithm can realize the adjustment range of the selected and high-speed turnout fine measurement technology analysis and Improve work efficiency.
