摘要： PURPOSE:To enable a reliable detection, for a track section through which signal current synchronous with the frequency of train current flows, by detecting the fact that asynchronous current has flowed in due to leakage baed on the presence of a higher harmonic component together with a modulated wave in the output of a demodulator. CONSTITUTION:A portion adjacent to a synchronous section TP and a asynchronous section TB which are separated by inserting an insulating material 4 to rails 3 is provided with a detection loop 5 composed of transceiver coil. The component of frequency fP is extracted from the train current PS of the synchronous section TP, a sending carrier wave fC1 is generated by an oscillator 12, a modulated wave fS of lower frequency thereof is also generated by an oscillator 14, a sum frequency fi is generated by a modulator 15, and a sending signal fA is generated by a modulator 16. On the other hand, the sending signal fA and the 15th higher harmonic wave fb of the current fS passing to the asynchronous section TB are extracted by BPF23 and given to a demodulator 24, the output thereof is sent to a detector 26, and a leakage detecting output is sent out when the higher harmonic component is larger than the modulated wave.

摘要： PURPOSE:To early discover an insulation deterioration by making the insulation resistance between rails of respective track sections detectable based on a rate of a detecting signal voltage at an adjacent portion to No.1 and No.2 track sections in which a signal current flows in a mutually asynchronized condition to a detecting signal voltage between both sections. CONSTITUTION:Around an adjacent portion of a synchronized section T1 and an asynchronized section T2 which are insulated by insulating materials RI1 and RI2, impedance circuits Z1 and Z2 are connected between respective rails R1 and R2 as well as R3 and R4, and impedance circuits Z3 and Z4 are connected at the portions apart a distance of lm from respective circuits Z1 and Z2 in the opposite direction to the adjacent portion. Between respective portions of rails R3 and R4 to which both circuits Z3 and Z4 are connected detecting signal generator OSC which generates a detecting signal of fS frequency is connected. A coil PC for detecting the detecting signal current is also attached to the rail R2 within a distance of lm, thereby a voltage Vy corresponding to the detecting signal current is extracted and inputted into a divider D so that the rate of Vy to the voltage VX of a detecting signal generated between both sections T1 and T2 can be obtained.

摘要： PURPOSE:To grasp the prediction of the front line state of a train by transmitting ATC information to the train with the carrier wave of higher frequency than that in the past to obtain much information, and generating a distance/speed curve from the point ATC information on the train. CONSTITUTION:The carrier wave of 80Hz rarely affected by the feeding frequency is AM-modulated by the frequency of several Hz, a track circuit is constituted with this track circuit signal to detect a train, and point ATC information is superimposed near the transmission end of the track circuit and transmitted/received to the train. A ground device detects the train with the track circuit arranged continuously, it determines the type of the 80Hz code signal S to be transmitted to the track circuit behind the train, it finds the interval of the track circuit unit between the front train position and the track circuit unit between the front train position and the track circuit, and it generates the point ATC information. An on-vehicle device generates a distance/speed curve based on the point ATC information received by point control and the train speed so that the train can be stopped before it collides from behind the preceding train, and a brake is operated to drive the train along the curve.

SOLUTION: A ground device 11, when detecting an existence position of a train 12 and a train 14 on a track circuit 16 by a train detecting device 11a, produces a control signal A on the basis of train control information corresponding to the existence position and vehicular performance of the main 12 a, and a control signal B on the basis of train control information corresponding to the existence position and vehicular performance of the train 14, and sends the signals A, B to the track circuit 16 by a control signal sending device 11b. Of the control signals A, B flowing in the track circuit 16, an on-vehicle device 13 on the train 12 receives only the signals A and automatically controls a traveling state of the train 12 according to the control signal A, and an on- vehicle device 15 on the train 14 receives only the signal B and automatically controls a traveling state of the train 14 according to the control signal B.
