    • PURPOSE:To simplify the positioning system by transmitting a speed command and a travel distance command signal from the ground side to an induction line laid on stationary secondary conductor and controlling the movement of the primary conductor, thereby enabling to position at the linear motor itselt. CONSTITUTION:A command controller 1, a modulator 2 and an induction line 4 laid along rails are provided on the ground side, and an antenna unit 6, a demodulator 7 and travelling distance and speed controllers 8, 9 are carried on a drive motor 11. The modulated command signal is outputted to the line 4, picked up by the antenna unit 6, demodulated, the signals of the speed detector 2 and the position detector 13 are fed back, thereby controlling the speed and the position. Accordingly, the position and the speed can be controlled by the linear motor itself merely by applying the command from the ground side. In this manner, the system can be simplified by eliminating the positioning mechanism on the rails.
    • 目的:为了简化定位系统,将速度指令和行进距离指令信号从地面侧传送到敷设在固定二次导体上的感应线,并控制主导体的移动,从而能够在直线电机的位置。 构成:在地侧设置有沿轨道布置的指令控制器1,调制器2和感应线4,天线单元6,解调器7和行驶距离和速度控制器8,9被承载在驱动马达11上 调制的指令信号被输出到由天线单元6拾取的线路4进行解调,速度检测器2和位置检测器13的信号被反馈,从而控制速度和位置。 因此,仅通过从地侧施加命令,可以通过线性电动机本身来控制位置和速度。 以这种方式,可以通过消除轨道上的定位机构来简化系统。

    • PURPOSE:To suppress the variation in the output of a gap sensor in case of passing the seam of iron rails by providing a seam compensator in a feedback circuit from the sensor to a power source side of a levitation electromagnet. CONSTITUTION:The first seam detector 6 is provided forward of moving direction of a gap sensor 1, and the second seam detector 7 is provided backward. When the detector 6 operates, an SCR20 is turned OFF, an SCR21 is turned ON to form the charger of a capacitor C. Thus, the sensor 1 detects the seam 19 of an iron rail 12 to generate the abrupt variation in the signal, which is absorbed to the capacitor C, and not input to a comparator 9. Then, when the detector 7 operates, the SCR20 is turned ON, and the SCR21 is turned OFF to discharge the capacitor C. Then, the signal from the sensor 1 is directly fed back to the comparator 9.
    • 目的:为了抑制在从传感器到悬浮电磁体的电源侧的反馈电路中设置接缝补偿器,在通过铁轨接缝的情况下,间隙传感器的输出的变化。 构成:第一接缝检测器6设置在间隙传感器1的移动方向的前方,第二接缝检测器7向后方设置。 当检测器6工作时,SCR20断开,SCR21导通,形成电容器C的充电器。因此,传感器1检测铁轨12的接缝19,以产生信号的突然变化, 被吸收到电容器C,而不被输入到比较器9.然后,当检测器7工作时,SCR20导通,SCR21断开,放电电容器C.然后,传感器1的信号为 直接反馈给比较器9。

    • PURPOSE:To detect the position of a vehicle with an inexpensive and simple facility by transmitting and receiving a specific signal through a propulsion coil between the vehicle and a rail side. CONSTITUTION:Transmission/reception antennas SC1, SC2 which have an air core coil, a Hall element, a loop or a rod antenna are provided on a vehicle TR which is opposed to propulsion coils LSM1, LSM2. Signals are transmitted and received via the antennas SC1, SC2 between the vehicle and the ground, thereby detecting the position of the vehicle. The coils LSM1, LSM2 are composed of the same structure, and when the same current is flowed through the coils LSM1, LSM2, thereby allowing the coils LSM1, LSM2 to provide the same propulsion force at the vehicle TR.
