Abstract

The invention provides a pipeline train positioning method and system based on stator coils of a synchronous linear motor. The stator coils, which are laid in a vacuum pipeline, of the synchronous linear motor are used as signal receiving coils, a signal transmitting coil is arranged on a pipeline train, and when the transmitting coil moves along the stator coils of the synchronous linear motor, atransmitted high-frequency signal is received by the stator coils of the synchronous linear motor. The method comprises the steps of acquiring received signal amplitudes of n phase stator coils of the synchronous linear motor and a waveform relationship between the n phase stator coils; calculating first position information of a target stator coil with the maximum current received signal amplitude in the n phase stator coils according to the coil length of the stator coil and the distance between the adjacent stator coils; determining the relative position information of the transmitting coil and the target stator coil according to the waveform relationship between the n phase stator coils; and determining the current position of the pipeline train according to the first position information and the relative position information so as to accurately position the pipeline train.

本发明提出了一种基于同步直线电机定子线圈的管道列车定位方法及系统，将铺设在真空管道中的同步直线电机定子线圈作为信号接收线圈，管道列车上设置信号发射线圈，当发射线圈沿同步直线电机定子线圈移动时，发射的高频信号被同步直线电机定子线圈接收，该方法包括：获取同步直线电机的n相定子线圈的接收信号幅值以及n相定子线圈之间的波形关系；根据定子线圈的线圈长度以及相邻定子线圈之间的间距，计算n相定子线圈中当前接收信号幅值最大的目标定子线圈的第一位置信息；根据n相定子线圈之间的波形关系确定发射线圈和目标定子线圈的相对位置信息；根据第一位置信息和相对位置信息确定管道列车的当前位置，准确地实现管道列车定位。
