摘要
针对磁悬浮列车运行时与轨道不接触的特殊性,利用电磁感应原理,提出一种采用位置标志板形式的绝对定位系统。对利用位置标志板进行检测的原理进行了介绍与分析,给出了求解接收线圈磁感应强度的计算公式,详细分析了在位置信息解码单元中对列车位置信息进行逻辑解码的过程。试验结果验证了系统的可行性。
Aiming at the particularity of no contact with the track during running of the maglev vehicle, the absolute positioningsystem using position identification boards is proposed based on the electromagnetic induction theory. The detecting principles of positionidentification boards are introduced and analyzed. The calculation formulas of magnetic flux density of receiving coils are presented. Thelogical decoding process of vehicle position information in the decoding unit is analyzed in details. The test results show that the detectingsystem is feasible.
