摘　　要：高速磁浮车辆悬浮间隙传感器为悬浮控制系统提供必要的间隙信息。相对定位传感器则分别为高速磁浮车辆牵引和运行控制提供同步直线电机次级极相角信息和速度信息。在分析两者应用差异的基础上,讨论了检测线圈结构设计、电路结构设计、动态特性、抗电磁干扰与抗温度漂移等共性技术。对悬浮间隙传感器而言,需弱化齿槽效应;对相对定位传感器而言,则需强化齿槽效应,以抑制悬浮间隙波动和减少传感器过接缝时的信号畸变程度。The levitation gap sensor of high-speed maglev train provides necessary gap information for the levitation control system.While the relative position sensor provides secondary phase angle and velocity information for the traction and operation control of high-speed maglev train respectively.Based on an analysis of their application differences,the common technologies like detection coil design,circuit structure design,dynamic characteristics,anti-electromagnetic interference and anti-temperature drift are discussed.For the levitation gap sensor,the cogging effect should be weakened,while for the relative position sensor,it is necessary to strengthen the cogging effect,in order to suppress the fluctuation of levitation gap and reduce the degree of signal distortion when the sensor passes through the joint.
