摘要： PROBLEM TO BE SOLVED: To accurately detect a travel position of a train by stably detecting a track circuit boundary on a vehicle.SOLUTION: When a signal receiving level of an ATC signal received by an on-board device 3 becomes lower than a threshold, the location A at that moment is determined as a tentative track circuit boundary. Thereafter, when the signal receiving level of the ATC signal becomes higher than the threshold, a carrier frequency or the like being the content of the ATC signal is confirmed. When the contents of the ATC signal before and after when the signal receiving level decreases and then increases are the same, the determined tentative track circuit boundary is discarded. When the contents of the ATC signal before and after when the signal receiving level decreases and then increases are different from each other, the determined tentative track circuit boundary is determined as the true track circuit boundary. Accordingly, even when the signal receiving level of the ATC signal that is received under the interference of an object existing in the vicinity of a railroad and hindering electromagnetic induction action decreases, the location where the signal receiving level decreases is prevented from incorrectly recognized as the track circuit boundary.
摘要翻译：要解决的问题：通过稳定地检测车辆上的轨道电路边界来精确地检测列车的行驶位置。解决方案：当由车载设备3接收到的ATC信号的信号接收电平变得低于阈值时，此时的位置A被确定为暂时轨道电路边界。此后，当ATC信号的信号接收电平变得高于阈值时，确认作为ATC信号的内容的载波频率等。当信号接收电平降低然后增加的ATC信号前后的内容相同时，确定的暂定轨道电路边界被丢弃。当信号接收电平降低然后增加的ATC信号的前后的内容彼此不同时，确定的暂定轨道电路边界被确定为真实轨道电路边界。因此，即使当在存在于铁路附近的物体的干扰下接收到的ATC信号的信号接收电平减小时，也可以防止信号接收电平降低的位置被错误地识别为轨道电路边界。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a power receiver that efficiently detects signal currents flowing across rails under no influence of electric railcar line currents and that can be reduced in size and cost. SOLUTION: A leading railcar is mounted on its first axle 3 with a substantially cylindrical coil 1a extending longitudinally to encircle the first axle 3, so that signal currents flowing across rails 51 and 52 via the first axle 3 are detected efficiently. The current detection is insusceptible of electric railcar line currents flowing from a line above the railcar to the rails 51 and 52 via the railcar, to thereby dispense with any equipment that counters interference currents caused by electric railcar line currents and reduce the device size and cost.

摘要： PROBLEM TO BE SOLVED: To reduce the cost by simplifying the configuration of the multiplex system transmitter. SOLUTION: Each transmitter 21 in the active system makes logical judgment based on a received external condition to generate and output a transmission signal and detects whether or not a fault takes place based on the voltage and the current of the outputted transmission signal. When any transmitter 21 in the active system is faulty, a transmitter 1 in the standby system receives the external condition that is received by the faulty transmitter 21 and generates and outputs the transmission signal in place of the transmitter 21. A changeover section 4 selects the transmission signal from the transmitter 21 in the active system or the transmission signal from the transmitter 31 in the standby system depending whether or not the transmitter 21 in the active system is faulty and provides the output of the selected transmission signal to a track circuit.
