  In the case of a train control signal transmission method using a conventional track circuit or a train control signal transmission method using a ground element such as a transponder, a train control ground device must be installed for each track circuit. There was a problem.

  Therefore, an object of the present invention is to enable train speed control by transmitting train control signals using overhead lines, thereby consolidating the transmission section of the track circuit, reducing equipment costs, and effectively using land. Is to plan.

  In order to solve the above-mentioned problems, the automatic train control device of the present invention uses a power transmission substation and an overhead line where the train is connected so that a train control signal can be communicated. Connect the train control ground device to the feeder control device in the facility. In addition, a transmission / reception unit is installed in the train so that signals from the overhead line can be received via the pantograph.

  According to the embodiment of the present invention, a train control ground device that generates a train control signal is installed in a substation that supplies power to an overhead line. In this configuration, since an existing substation is used, it is not necessary to newly install a train control ground device in an unequipped section of the train control ground device.

  In the train control on-board device, speed control is performed using a train control signal converted by a transmission / reception unit that receives a signal, and an existing device is used except for the transmission / reception unit. For this reason, in this structure, it can apply to the conventional train control on-board apparatus, and it is not necessary to apply a train control on-board apparatus newly.

  According to the present invention, the train control signal can be transmitted over a wide range of the feeding section by transmitting the train control signal using the overhead line. As a result, train control ground devices installed at each station can be aggregated at each substation, so that facilities can be simplified, maintainability can be improved, and costs can be reduced.

FIG. 1 is a block diagram showing an embodiment of an automatic train control device of the present invention. FIG. 2 is a block diagram showing an embodiment of the transceiver of the present invention. FIG. 3 is a block diagram showing a conventional automatic train control apparatus.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, an example applied to an ATC system will be described as an example of a train control signal.

  FIG. 1 shows an overall configuration diagram of an embodiment of the present invention. The substation 2 includes an ATC ground device 3 that calculates and transmits an ATC signal according to train position information, a feeder control device 4 that controls overhead power and applies an ATC signal from the ATC ground device to the overhead wire voltage, and an overhead wire. A feeder transformer 5 for supplying voltage is provided.

  The train 8 includes a pantograph 7 that receives power transmitted from the substation 2 through the overhead line 6, a motor 9 that runs the train 8 with the power from the pantograph 7, and a transceiver that receives the ATC signal from the pantograph 7 11, a speed generator 13 that outputs the rotational speed of the wheel 14, an ATC on-board device 10 that performs a speed check from the ATC signal converted by the transceiver 11 and the train speed output from the speed generator 13, and ATC A brake device 12 that controls the train speed according to a brake instruction from the on-board device 10 is provided.

  The operation of the ATC system configured as described above will be described. For example, the presence of a train is detected using a track block by the track circuit of the rail 17. The train position information specified by the train presence line detection is sent to the ATC ground device 3. The ATC ground device 3 generates an ATC signal based on the train position information. The feeder control device 4 controls the ATC signal generated by the ATC ground device 3 to be transmitted to the overhead line 6.

  The converted ATC signal is transmitted to the train 8 via the overhead line 6. The ATC signal transmitted via the overhead line 6 is received by the train 8 via the pantograph 7. The ATC signal received by the train 8 is converted into a signal corresponding to the ATC on-board device 10 by the transceiver 11.

  The ATC signal converted by the transceiver 11 is transmitted to the ATC on-board device 10. The ATC on-board device 10 calculates the train speed from the speed pulse signal obtained from the speed generator 13. The ATC on-board device 10 issues a brake instruction based on the train speed obtained by the calculation and the speed limit information based on the ATC signal. The brake device 12 limits the speed of the train in accordance with a brake instruction from the ATC on-board device 10.

  FIG. 2 shows a configuration diagram of an embodiment of the transceiver 11 of the present invention. As shown in FIG. 2, the transceiver 11 transforms the ATC signal received from the overhead line 7 via the transformer 31. The transformed ATC signal is noise-removed by the filter 32, demodulated into a signal corresponding to the ATC on-board device 10 by the demodulator 33, and output to the ATC on-board device 10.

  Since the ATC signal is transmitted using the overhead line 6, the same ATC signal is transmitted to a plurality of trains in a section which is the same substation section. Therefore, the ATC ground device 3 generates a digital signal as the ATC signal and adds train identification information to the signal. In addition, the ATC signal to each train is sent simultaneously. The ATC on-board device 10 discriminates the identification number of the ATC signal and extracts only the ATC signal to the own train.

  As a result, the ATC ground device 3 can transmit different ATC signals to a plurality of trains in the same section.

  Since the conventional ATC ground device is installed in each block section and is controlled so that only one train can enter the block section, the ATC ground device has an ATC signal for one train. It is sufficient to transmit ATC, and it is not necessary to transmit ATC signals to a plurality of trains at the same time. However, since the section of the section of the same substation is generally wider than the closed section, it will span multiple closed sections. Therefore, in the present invention, the possibility of transmitting ATC signals simultaneously to multiple trains There is.

  In the present invention, ATC ground devices are arranged in each substation section. However, since the section of the same substation section is generally wider than the closed section, the present invention can reduce the number of ATC ground devices. It becomes possible.

  In the above-described embodiment, the example in which the overhead line 6 is used to transmit the ATC signal from the ATC ground device 3 to the ATC on-board device 10 has been described. However, in this embodiment, the transceiver 11 has the modulation unit 34. Therefore, it is also possible to modulate information such as the train position of the train 8 by the modulation unit 34 and transmit the information to the ATC ground device 3 through the overhead line 6.

  When information such as the train position is transmitted from the train 8 to the ATC ground device 3, a signal transmitted from the ATC onboard device 10 is output to the transceiver 11. A signal from the ATC on-board device 10 is modulated by the modulation unit 34 in the transceiver 11 and transformed through the transformer 31. The transformed signal is transmitted to the substation 2 through the pantograph 7 and the overhead line 6, and the ATC ground device 3 in the substation 2 receives this signal.

  In the above-described embodiment, an example in which a track circuit is used as a means for recognizing the train position has been described. However, the present invention is not limited to this embodiment, and the transponder upper member 15 is provided for each train and the ground. It is good also as a means to recognize a train position by providing the transponder ground element 16. FIG.

  In this embodiment, the train 8 is provided with a transponder upper element 15 and a transponder ground element 16 on the ground. The train position is acquired by these, and the train position information is transmitted to the ATC ground device 3 using the overhead line 6. Send. The ATC ground device 3 recognizes the train position based on the train position information from the overhead line 6 and uses it for train control.

  In the above-described embodiment, the overhead line 6 is used as a means for receiving an ATC signal. However, the overhead wire 6 is not limited to this, and may be combined with a conventional track circuit as a means for transmitting an ATC signal. In this case, the ATC signal transmission means from the ATC ground device to the train can be made redundant.

  In the above-described embodiment, an example in which the ATC signal is supplied to the train using the power supply overhead line 6 is shown. However, the ATC signal is supplied to the train using a power supply side rail such as a subway or a monorail. It is also possible. Of course, the control target need not be a train composed of a plurality of vehicles, and may be a vehicle.
