자기부상 열차 상하좌우 편위가 절대위치검지 장치의 수신 전압에 미치는 영향 연구

초록

In this paper, an absolute position detection system composed of a marker plate and transmitting？receiving loop antennas is investigated, and the effects of vertical and horizontal misalignments of the vehicle on the received induced voltage and address code discrimination performance are analyzed. Electromagnetic simulations are conducted to analyze the received voltage characteristics according to the slot width of the marker plate and the vertical and lateral margin lengths. The results show that, under vertical misalignment conditions of ±200 mm, increasing the distance between the marker plate and the loop antennas to 50 mm is effective in achieving stable code discrimination. In addition, it is confirmed that code misidentification occurs when the marker plate approaches the transmitting antenna under horizontal misalignment conditions. To address this issue, a method of applying transmitting signals with different frequencies to adjacent transmitting coils is proposed.
