摘要：
In the next generation of the column control system (NGTC), it is proposed to use the onboard equipment to achieve train integrity monitoring and minimize the requirements of wayside equipment. This paper proposes a train integrity monitoring method based on the global satellite navigation system (GNSS) moving baseline. Two antennas are set up at the head and end of the train. The errors of propagation path and clock is eliminated by using carrier phase difference between satellites and two antennas. The length of moving baseline is calculated in real time and compared with the reference train length to realize the integrity monitoring. To evaluate the performance of the proposed algorithm, a real train test was carried out on the Beijing-Shenyang high speed railway in China. The experimental results show that the proposed train integrity resolution method can provide train integrity solutions with an accuracy of 0.5 meters or better, which is significantly improved compared with the maximum 1.3-meter error of single point positioning.
