Description

  The present invention provides a train such as ATC (Automatic Train Control) or ATS (Automatic Train Stop) that performs train control such as speed control by transmitting a predetermined signal from the ground to the vehicle. The present invention relates to a control device.

  In recent years, with the high-speed operation and high-density operation of trains, digital transmission type train control devices are often employed.

  On the ground side of the train control device adopting this digital telegram type train control, a carrier wave having a predetermined frequency is modulated with predetermined train control information and a predetermined digital signal is generated for transmission on the vehicle. The generated digital signal is transmitted to the starting end side of the rail that generates the track circuit through the transmitter. In the on-board device of the train traveling on the rail, the train control information transmitted to the rail is received via the power receiver, the received signal is demodulated, and based on the train control information It is configured to perform predetermined train control. The on-board device is based on the fact that it always receives a signal from the ground side, and when this signal cannot be received for a certain period of time or when it cannot be received as meaningful information (the latter refers to a digital system). ), Stop the train emergencyly, judging it dangerous.

  By the way, in the train control device of the digital transmission system, the digital signal is meaningful only after receiving a signal of a certain length (number of bits). It will take some time.

  In the prior art, the digital signal is always generated and transmitted by the ground device regardless of whether the train is present or not, and when the train enters the track circuit, the on-board device transmits the digital signal. To be able to receive.

  However, in the above method, when a plurality of types of trains having different signal systems pass through the track circuit, a plurality of types of signals are always transmitted on the same rail. In the track circuit divided into a plurality of track circuits in the same line section, in addition to the train control device, a train detection device, a crossing control, etc. are provided on each track, the control frequency bands of those devices are different from each other, The frequency is assigned so as not to affect the control. As a result, the frequency band that can be used by this train control device is limited, so the frequency assigned to each signal of a plurality of different signal systems is inevitably close, and the plurality of train control signals are likely to affect each other. End up. In this case, the influence of interference between signals must be taken into account, and there is a problem that the reliability of the system is lowered.

  Patent Document 1 discloses a method of distinguishing signals by adding digital ATC signal information of the next trajectory to a digital telegram. However, complicated information is added to the signal scheme of the applicable section. If there is an analog type that cannot be performed, the method of Patent Document 1 cannot be applied. In addition, when the method of Patent Document 1 is performed in a case where a new signal system train is newly run in a section (track circuit) in which a certain signal system train is already running, the existing signal system is disclosed in Patent Document 1. It may be necessary to change the on-board equipment to match the system.

  As another conventional technique, there is a method in which after detecting that a train has entered the track circuit that transmits a digital signal, a digital telegram is generated and transmitted to the track circuit. However, in this case, the ground device needs a certain amount of time to detect that the train has entered the track circuit that transmits the digital signal, and to generate the digital signal and transmit it to the track circuit. The on-board device is slow to receive the digital signal. When the train passes through the track circuit at high speed or the track circuit is short, the train passes through the track circuit until the on-board device finishes receiving the digital signal transmitted by the ground device. There is a possibility that the on-board device cannot receive the signal as meaningful information, and the on-board device cannot receive the digital signal within a certain time, and causes the emergency stop of the train.

JP 2008-37155 A

  An object of the present invention is to prevent interference between different signals on the same rail when a plurality of types of trains having different train control signal systems pass through the track circuit, and to improve the reliability of the train control system.

  In the present invention, when a plurality of trains having different signal systems of the train control signal pass through the rail, a train detection device that determines the presence of the train in the track circuit and the type of the train, and the train control in the track circuit A transmitter that transmits a signal, and the transmitter receives information on the presence of the train in the track circuit and the type of the train from the train detection device, and a signal-based train corresponding to the type of the train By adopting a configuration in which the control signal is transmitted to the track circuit, it is not necessary to transmit a plurality of types of signals on the same rail.

  Furthermore, the ground device transmits not the track information (entrance) information of the track circuit but the train track information and type information detected by other track circuits on the train approach side to the track circuit. A signal can be transmitted in advance before the train enters.

  According to the present invention, when multiple types of trains having different signal systems pass through the track circuit, different signals do not interfere with each other on the same rail, and the reliability of the train control system can be improved.

It is a figure which shows operation | movement of the ATC ground apparatus when the train 30a drive | works in Example 1 of this invention. It is a figure which shows operation | movement of the ATC ground apparatus when the train 30b drive | works in Example 1 of this invention. It is a figure which shows operation | movement of the ATC ground apparatus when the train 30c drive | works in Example 2 of this invention.

  Two examples will be described below.

  As an example in which different types of trains with different signal systems pass through the same track circuit, a case where ATC is applied to a three-track track is shown as a first embodiment.

  1 and 2 show the configuration of the first embodiment of the present invention. 21, 22, and 23 represent rails, and the three rails are divided by track circuits 1T, 2T, 3T, and 4T (this divided configuration continues even outside the figure). On this track circuit, there are a train 30a that runs on the rails 21 and 23 and a train 30b that runs on the rails 21 and 22. The case where the train 30a travels is described with reference to FIG. 1, and the case where the train 30b travels is described with reference to FIG. In the following description, it is assumed that each train travels on a track circuit in the order of 1T, 2T, 3T, and 4T.

  When the train 30a (see FIG. 1) travels on the track circuits 2T and 3T, the ATC signals 11a and 11b flowing in the track circuits are received by the receiving antenna 32a on the vehicle, and the on-board device 33a is based on the information. Controls the running of the train 30a. If the on-board device 33a fails to receive the ATC signals 11a and 11b for a certain period of time or cannot be received as meaningful information (the latter is based on the digital method), the on-board device 33a determines that it is dangerous and stops the train 30a. (Note that although the description is omitted, the same applies to the track circuits 1T and 4T.)

  Even when the train 30b (see FIG. 2) travels on each track circuit 2T, 3T, the onboard device controls the train by the ATC signal flowing in the track circuit, but the train 30b is different in signal system from the train 30a. The ATC signals 12a and 12b, which are different from 11a and 11b, are received by the receiving antenna 32b, and the onboard device 33b controls the traveling of the train 30b. Similarly, the on-board device 33b stops the train 30b when the ATC signals 12a and 12b cannot be received for a certain period of time or when it has not been received as meaningful information (in the case of a digital system) (even when running on the track circuits 1T and 4T). The same.)

  In FIG. 1, when a train 30a enters the track circuit 2T, the rails 21, 23 are electrically short-circuited by the axle 31a, and the track relay 2a (for detecting the train on the rails 21, 23) inside the train detection device 1a. ) Falls. At this time, the track relay 3a (for detecting a train on the rails 21 and 22) is not connected to the rail 23 and therefore does not fall. The train presence line train type determination unit 4a constantly monitors the status of the track relays 2a and 3a, and when the track relay 2a operates (falls), the train has entered and the train type is the train 30a. When the track relay 3a operates (falls), it is determined that the train has entered and that the type of the train is the train 30b. When the track relay 2a operates, the train presence line type determination unit 4a uses the determined train presence line train type information 13 on the ground side ATC installed in the track circuit 3T adjacent to the advancing side (train traveling direction). Transmit to device 5b. Based on the train presence train type information 13, the ATC signal generator 8b generates a control signal of the signal system of the train 30a, and the ATC signal 11b (train 30a) from the ATC signal transmitter 6b (for transmission to the rails 21 and 23). Is previously transmitted to the track circuit 3T before the train 30a enters. Thereby, when the train 30a passes the track circuit 2T and enters 3T, the on-board antenna 32a can immediately receive the ATC signal 11b.

  Thereafter, when the train 30a advances into the track circuit 3T and enters the track circuit 4T, the track relay 2b (for detecting the train on the rails 21 and 23) rises, and the train existing line train type determination unit 4b Train presence line information 15 is transmitted to the side ATC device 5b. In this way, when receiving the information of the train presence line that changes from the standing line to the non-present line, the ground side ATC device 5b stops the transmission of the ATC signal 11b (for the train 30a) to the track circuit 3T. With such a configuration, when the train is not present in either the previous track circuit or the track circuit, the ATC signal can be configured not to be transmitted to the track circuit, and the signal is always transmitted. In comparison, it saves energy.

  Here, in the present embodiment, the digital signal corresponding to the train type is transmitted to the track circuit adjacent to the advance side of the train. There may be.

  It takes some time to detect that a train has entered the track circuit, generate a digital signal, and transmit this digital signal to the track circuit. Therefore, in the prior art, it takes time for the on-board device to receive the digital signal, and when the train passes through the track circuit at a high speed or the length of the track circuit is short, the ground device transmits. The train may pass through the track circuit before the on-board device has received the digital signal, and the on-board device cannot receive the signal as meaningful information and must stop the train in an emergency. There was a problem that had to be done.

  On the other hand, according to the present embodiment, the digital signal is transmitted by transmitting a digital signal corresponding to the type of train that has detected the existing line to the other track circuit on the advancing side than the track circuit that detects the existing line of the train. The time until the on-board device finishes receiving can be shortened compared to the conventional case, and the problem that the train must be stopped can be solved.

  If the ATC signals 11b and 12b are always transmitted to the track circuit 3T, 11b and 12b will interfere with each other on the rail 21, so that frequencies that do not affect each other are selected and the on-board antenna is selected. It is necessary to take a countermeasure such as selecting only 11b by 32a or on-vehicle device 33a. Therefore, it is necessary to make the on-board device a high-performance device, resulting in a high cost, and there is a problem that the reliability of the system is lowered due to the influence of interference between signals.

  In the present embodiment, since only the necessary one of the ATC signal 11b for the train 30a or the ATC signal 12b for the train 30b is selected and transmitted, it is not necessary to improve the performance of the on-board device more than necessary. System reliability can also be improved.

  In FIG. 1, in order to make the state of interference easy to understand, 12b appears to be transmitted, but in this embodiment, 12b is not transmitted in the state of FIG.

  Next, in FIG. 2, when the train 30b enters the track circuit 2T, the rails 21 and 22 are electrically short-circuited by the axle 31b, and the track relay 3a inside the train detection device 1a falls. At this time, since the track relay 2a is not connected to the rail 22, it does not fall. The train presence line train type determination unit 4a determines that the train has entered by the operation (falling) of the track relay 3a and the type of the train is the train 30b, and sends the train presence line train type information 13 to the track circuit 3T. It transmits to the installed ground side ATC device 5b. Based on the train presence train type information 13, the ATC signal generation device 8b generates a control signal for the train 30b, and sends an ATC signal 12b (for train 30b) from the ATC signal transmitter 7b (for transmission to the rails 21 and 22). It is transmitted in advance to the track circuit 3T.

  Thus, when the train 30b passes through the track circuit 2T and enters the track circuit 3T, the on-board reception antenna 32b can immediately receive the ATC signal 12b.

  Thereafter, when the train 30b advances into the track circuit 3T and enters the track circuit 4T, the track relay 3b (for detecting the trains on the rails 21 and 22) rises, and the train existing line train type determination unit 4b Train presence line information 15 is transmitted to the side ATC device 5b. When receiving the train presence information 15, the ground side ATC device 5b stops transmitting the ATC signal 12b (for the train 30b) to the track circuit 3T. With such a configuration, when the train is not present in either the previous track circuit or the track circuit, the ATC signal can be configured not to be transmitted to the track circuit, and the signal is always transmitted. In comparison, it saves energy.

  Similar to the effect of the present embodiment described in the description of FIG. 1, even in the case of FIG. 2 where the train 30b enters, the track is detected in another track circuit on the advancing side than the track circuit that performs the track detection of the train. By transmitting a digital signal according to the train type, the time until the on-board device finishes receiving the digital signal can be shortened compared to the conventional case, and the problem that the train has to be stopped can be solved. In addition, since the ATC signal corresponding to the train type is selected and transmitted, it is not necessary to improve the performance of the on-board device more than necessary, and the reliability of the system can be improved.

  In other words, when a plurality of types of trains with different signal systems pass through the track circuit, a train that flows on the rail is determined by determining the train that is on the line and selecting and transmitting only the signal corresponding to the train. There is only one type of control signal, and there is no need to consider interference of multiple signals.

  Furthermore, in the system of the present embodiment, it is possible to cope with cases where various types of signal trains pass through the track circuit. For example, even when a plurality of signals to be transmitted use the same frequency band and are different only in digital and analog, this system can be realized. In addition, even when a new signal train is running in a section where a signal-driven train is already running, the ground device side selects and transmits a signal, so the existing on-vehicle device side changes. Is no longer necessary.

  Furthermore, even when the train passes through the track circuit at a high speed or when the track circuit is short, by sending a signal to the track circuit on the advance side, when the train enters the track circuit, The on-board device can receive the signal. In addition, when the train is not on either the previous track circuit or the track circuit (when the train location information is not received from the train presence train type determination unit installed in the previous track circuit), no signal is transmitted. It can be configured and saves energy compared to a configuration that always transmits signals.

  In the first embodiment, the case where the present invention is applied to a three-track rail is described as an example, but in the second embodiment, a case where the present invention is applied to a general track circuit including two rails is described as an example.

  FIG. 3 shows a configuration according to the second embodiment of the present invention. The main differences from the first embodiment are that the rails constituting the track circuit are two rails 21 and 23, and the means for determining the type of train is different.

  There are 30c and 30d as trains traveling on this track circuit, and their signal systems are different. FIG. 3 shows a case where the train 30c travels. In the first embodiment, the type of the train is determined by detecting the difference between the rails passing by the train. However, in this embodiment, there are two rails constituting the track circuit, and both the trains 30c and 30d have the same rail 21. , 23, the type of train cannot be determined depending on the rail through which the train passes.

  Therefore, as an example of determining the train type, FIG. 3 shows a method of installing the ground side transponders 9a and 9b on the ground side and the vehicle side transponder 34c on the vehicle upper side. A detailed method will be described below.

  When the train 30c enters the track circuit 2T, the rails 21 and 23 are electrically short-circuited by the axle 31c, and the track relay 2a inside the train detection device 1a falls. The train presence line train type determination unit 4a detects the approach (present line) of the train by the operation (falling) of the track relay 2a. On the other hand, when the vehicle-side transponder 34c passes over the ground-side transponder 9a installed in the track circuit 2T, the vehicle-side transponder 34c transmits information representing the train type (that is 30c) of the own vehicle to the ground-side transponder 9a. . The ground side transponder 9a transmits the received information to the train presence line train type determination unit 4a. The train presence line train type determination unit 4a determines the train type based on information from the ground side transponder 9a. The train presence line train type determination unit 4a determines the train presence line detection and the train type, and then determines the determined train presence line train type information 13 on the ground side ATC device 5b installed in the track circuit 3T adjacent to the advance side. Send to. The ATC signal generation device 8b generates a control signal for the train 30c based on the train presence line train type information 13, and the ATC signal 14b for the train 30c (for the train 30c) from the ATC signal transmitter 6b to the track circuit 3T in advance. Send it. Thereby, when the train 30c passes the track circuit 2T and enters 3T, the on-board antenna 32c can immediately receive the ATC signal 14b.

  Thereafter, when the train 30c advances into the track circuit 3T and enters the track circuit 4T, the track relay 2b (for detecting the train on the rails 21 and 23) rises, and the train existing line train type determination unit 4b Train presence line information 15 is transmitted to the side ATC device 5b. Upon receiving this train presence line information 15, the ground side ATC device 5b stops transmitting the ATC signal 14b (for the train 30b) to the track circuit 3T. With such a configuration, when the train is not present in either the previous track circuit or the track circuit, the ATC signal can be configured not to be transmitted to the track circuit, and the signal is always transmitted. In comparison, it saves energy.

  Here, in the present embodiment, the digital signal corresponding to the train type is transmitted to the track circuit adjacent to the advance side of the train. There may be.

  Moreover, although it was set as the structure provided with the train presence line train classification determination part 4a which determines the train presence line and the train type in FIG. 3, the ground side ATC apparatus which is performing the train presence line and is installing the train presence line information in the advance side And a train type determining unit that determines the type of train and transmits train type information to the ground side ATC device installed on the advancing side.

  In the present embodiment, in the same manner as in the first embodiment, the digital signal is transmitted by transmitting a digital signal corresponding to the type of train that has detected the line to another track circuit on the advancing side than the track circuit that performs the track detection. The time until the on-board device finishes receiving the vehicle can be shortened compared to the conventional case, and the problem that the train must be stopped can be solved. Further, since the ATC signal corresponding to the train type is selected and transmitted, it is not necessary to improve the performance of the on-board device more than necessary, and the reliability of the system can be improved.

  In other words, when a plurality of types of trains with different signal systems pass through the track circuit, a train that flows on the rail is determined by determining the train that is on the line and selecting and transmitting only the signal corresponding to the train. There is only one type of control signal, and there is no need to consider interference of multiple signals.

  Furthermore, in the system of the present embodiment, it is possible to cope with cases where various types of signal trains pass through the track circuit. For example, even when a plurality of signals to be transmitted use the same frequency band and are different only in digital and analog, this system can be realized. In addition, even when a new signal train is running in a section where a signal-driven train is already running, the ground device side selects and transmits a signal, so the existing on-vehicle device side changes. Is no longer necessary.

  Furthermore, even when the train passes through the track circuit at a high speed or when the track circuit is short, by sending a signal to the track circuit on the advance side, when the train enters the track circuit, The on-board device can receive the signal. In addition, when the train is not present in either the previous track circuit or the track circuit, it is possible to adopt a configuration in which no signal is transmitted. Therefore, energy is saved as compared with a configuration in which a signal is always transmitted.

  Although the case where the train 30d travels is not shown, when the train 30d passes over the ground-side transponder 9a, information indicating the train type (that is, the train 30d) of the train 30d different from the train 30c is displayed on the ground side. Transmit to the transponder 9a.

  Thereafter, similarly to the progress of the train 30c, the train presence line train type determination unit 4a determines the presence line and the train type of the train 30d, and transmits the train presence line train type information 13 to the ATC signal generation device 8b. When the train 30d passes through the track circuit 2T and enters 3T by the ATC signal generating device 8b transmitting the ATC signal 15b for the train 30d to the track circuit 3T in advance with the train presence train type information 13, the train 30d Can immediately receive the ATC signal 15b.

  As a means for judging the type of train, a transponder is given as an example in this embodiment, but as another means, the distance between different axles is measured depending on the train by using an axle detector to determine the type of train. It can also be configured using a method of judging, or a method of judging the type of train by reading the shape of the vehicle body or the train number display using a camera.

  According to the present embodiment, the present invention can be applied even when a plurality of trains having different train control signal systems travel on the two-track rail, and the same effects as those of the first embodiment can be achieved.
