Description

  The present invention relates to a train control device.

  As a train operation control system, a route (track) of a train is divided at a predetermined distance and a block section is provided, and a train control is performed in accordance with the principle of one block section and one train (hereinafter referred to as fixed block operation). In general).

  Patent Document 1 discloses an ATC (Auto Train Control) system of a fixed block operation method using a loop. In the ATC system described in Patent Document 1, a closed section fixed at a fixed distance is configured by a loop embedded along a track. The speed limit of each loop is, for example, when a forward train exists in the loop, the speed limit of the loop one backward from the loop is 10 km / s, and the speed limit of the loop two backwards from the loop is 30 km / s, the speed limit of the loop three backwards from the loop is set to 50 km / s. And a back train checks train speed with an on-board device so that train speed may become below a limit speed, generates a stop pattern, and performs train control.

As described above, in the ATC system of the fixed block operation method, the speed control is performed in units of fixed block sections, and therefore the length of each block section cannot be changed. For this reason, the freedom degree of train control was restrict | limited, and there existed a certain limit in the shortening of the train operation time interval (operation time interval), the shortening of the train operation time, and the improvement of the train speed.
JP 2002-67957 A (page 2-3, FIG. 1)

  The subject of this invention is providing the train control apparatus which can implement | achieve shortening of the operation time interval of a train.

  Another subject of this invention is providing the train control apparatus which can implement | achieve shortening of the operation time of a train.

  Still another object of the present invention is to provide a train control device that can realize an increase in train speed.

  In order to solve the above-described problem, the train control device according to the present invention includes a loop and a ground device.

  The loop is laid along the track of the train, and a train signal is supplied from an on-board device of the train existing in the loop. The train signal includes train number information of the train and train speed information of the train.

  The ground device is supplied with a train signal through a loop, calculates a front inter-vehicle distance based on the train based on the train signal, and stops for the train based on the front inter-vehicle distance and train speed information. A pattern is generated, and a speed control signal generated based on the stop pattern is output to the loop.

  As described above, the train control device according to the present invention includes a loop. Since the loop is laid along the track of the train, the train signal is supplied from the on-board device of the train existing in the loop. For example, when two or more trains exist in the loop, two or more train signals are supplied to the loop.

  The train signal includes train number information of the train and train speed information of the train. The train signal may further include information (hereinafter referred to as train position information) for specifying the position of the train obtained using a ground element or the like. The train signal may be an analog signal or a digital signal.

  Moreover, in the train control device using the track circuit, when there are two or more trains in the closed section, the train signal cannot be received due to the short-circuit of the train axle, but the train control device according to the present invention is Since the loop is used, the axle short circuit does not occur. Therefore, a train signal can be sent to two or more trains existing on the loop.

  The train control device according to the present invention includes a ground device. Since the ground device is supplied with the train signal through the loop, the train that has output the train signal can be identified based on the train number information of the train signal even when there are two or more trains in the loop. Moreover, the ground device can identify the position of the train that has output the train signal by time-integrating the train speed information of the train signal from the time when the train enters the loop. Moreover, when the train position information is included in the train signal, the ground device can also specify the position of the train that has output the train signal using the train position information.

  Thus, since the ground device can specify the train that has output the train signal and the position of the train, it can calculate the front inter-vehicle distance based on the train. Specifically, for example, the ground device can set the distance to the end point of the section where the loop is embedded for the frontmost train in the loop, and the rear train in the loop, The distance to the front train can be the front inter-vehicle distance. Similarly, when there is only one train in the loop, the ground device can set the distance to the end point of the section in which the loop is embedded as the front inter-vehicle distance.

  Further, since the ground device can identify the speed of the train that has output the train signal based on the train speed information of the train signal, the ground device generates a stop pattern for the train based on the front inter-vehicle distance and the train speed information. The speed control signal generated based on the stop pattern can be output to the loop. The speed control signal is a signal used for train speed control of the on-board device, and includes, for example, speed limit information, brake notch information, and the like.

  Moreover, in the train control device using the track circuit, when two or more trains exist in the block section, the train control device according to the present invention cannot transmit the speed control signal due to the train axle short circuit. Since the loop is used, such inconvenience does not occur.

  As described above, in the train control device according to the present invention, the ground device grasps the relative positional relationship between the train existing in the loop and the train ahead of the train, and checks the train speed. A stop pattern can be generated. Further, the ground device can output a speed control signal to the train existing in the loop and the train ahead thereof, and can control the train and the train ahead thereof. For this reason, even if two or more trains enter the loop, there is no possibility of a train collision, and therefore, it becomes possible to perform a moving closed operation in the loop.

  In the moving block operation method, since the block section is not fixed, the length of each block section can be easily changed. For this reason, the freedom degree of train control increases and it can implement | achieve shortening of the operation time interval (operation time interval) of a train, shortening of the operation time of a train, and the improvement of a train speed.

  Moreover, in the train control apparatus which concerns on this invention, since it becomes possible to operate many trains in one loop, the number of loops to be used can be reduced as the whole train operation area. For this reason, the increase in equipment costs, such as a ground device provided corresponding to a loop, can be suppressed by the reduction | decrease of the number of loops.

  Other features of the present invention and the operational effects thereof will be described in more detail by way of examples with reference to the accompanying drawings.

  FIG. 1 is a diagram illustrating an embodiment of a train control device according to the present invention. The illustrated train control device is an ATC (Auto Train Control) system using a loop. This type of system can be applied to, for example, a new transportation system such as a rubber tire system, a monorail, and the like.

  In the figure, the ground device 20 is provided on the ground. The loops 110, 111, and 112 are induction loops and are laid along the train track 100. In the loop 111, trains 91 and 92 are present. The trains 91 and 92 travel in the direction of the arrow shown in the figure. An on-board device 811 is provided on the train 91, and an on-board device 812 is provided on the train 92.

  The illustrated train control device includes a loop 111, a ground device 20, on-vehicle devices 811 and 812, field matching devices 31 and 32, an interlock device 33, and a power supply device 34. The on-board devices 811 and 812 include a transmitter and a receiver. The transmitter is a device that generates a train signal S11 described later, and the receiver is a device that performs a train control by processing a speed control signal S21 described later. The field matching units 31 and 32 are, for example, transformers, and are devices that transmit signals between the loop 111 and the ground device 20.

  The ground device 20 includes matching transformers 21 and 22, a signal transmission / reception controller 23, and an interlocking interface 24. The matching transformers 21 and 22 are, for example, transformers, and are devices that perform signal transmission between the field matching units 31 and 32 and the signal transmission / reception controller 23. The signal transmission / reception controller 23 is a device that processes the train signal S11 and generates the speed control signal S21.

  In the train control device described above, the on-board device 811 uses the train number information of the train 91 stored in advance and the train speed information of the train 91 generated using a speed generator (not shown). A train signal S11 is generated. The on-board device 812 generates the train signal S11 using the train number information of the train 92 stored in advance and the train speed information of the train 92 generated using a speed generator (not shown). . The organization number information is used as a train ID (identification).

  Moreover, when a ground element is laid along the train track 100, information (hereinafter referred to as train position information) for specifying the positions of the trains 91 and 92 can be generated using the ground element. In this case, it is preferable that the train signal S11 includes train position information.

  The train signal S11 is supplied to the loop 111 from the onboard devices 811 and 812 via the antenna 821. The train signal S11 supplied to the loop 111 is supplied to the matching transformer 21 of the ground device 20 via the field matching unit 31. The matching transformer 21 converts the supplied train signal S11 into a predetermined voltage signal and outputs it to the signal transmission / reception controller 23.

  The signal transmission / reception controller 23 calculates a front inter-vehicle distance based on the train based on the train signal S11. As shown in FIG. 1, since the train 91 is a rear train of the train 92, the front inter-vehicle distance is the distance to the front train 92 (the distance to the train positions X0 to X10).

  Thereafter, the signal transmission / reception controller 23 generates a stop pattern for the train based on the front inter-vehicle distance and the train speed information. In generating the stop pattern, it is preferable to identify the train that has output the train signal S11 based on the train number information of the train signal S11 and to set the stop pattern according to the brake performance of the train.

  FIG. 2 is a diagram illustrating a stop pattern generated by the signal transmission / reception controller. In FIG. 2, the horizontal axis is the train position, and the vertical axis is the speed limit. The illustrated stop pattern is a stop pattern used for controlling the train 91. The illustrated stop pattern is a substantially constant speed limit up to the train position X6, and the speed limit is lower when the train position X6 is exceeded.

  In FIG. 1 again, the signal transmission / reception controller 23 generates the speed control signal S21 based on the stop pattern, and outputs the speed control signal S21 to the matching transformer 22. The speed control signal S21 includes composition number information and control information. The control information is, for example, speed limit information or brake notch information.

  When the speed control signal S21 includes speed limit information, the speed limit information may be a part of the stop pattern or the entire stop pattern, for example. The part of the stop pattern is, for example, each speed limit value at the train positions X0, X1, X2,... X10, a stop pattern curve to the train positions X0 to X5, or the like.

  The matching transformer 22 outputs the supplied speed control signal S21 to the field matching device 32. The field matching unit 32 outputs the supplied speed control signal S21 to the loop 111. The loop 111 outputs a speed control signal S21 to the antenna 821 of the trains 91 and 92.

  The on-board device 811 receives the control information included in the speed control signal S21 when the composition number information included in the speed control signal S21 matches the train ID (composition number information) of its own, and does not match Does not receive the control information included in the speed control signal S21.

  Similarly, the on-board device 812 receives the control information included in the speed control signal S21 when the composition number information included in the speed control signal S21 matches the train ID (composition number information) of its own, and matches. If not, the control information included in the speed control signal S21 is not received.

  Thereafter, the on-board devices 811 and 812 perform train control based on the control information. Specifically, for example, when the control information is speed limit information, the on-board devices 811 and 812 perform train control so that the speed is equal to or lower than the speed specified by the speed limit information, and the control information is brake notch information. In this case, the on-board devices 811 and 812 operate the power running brake specified by the brake notch information and perform train control.

  Further, the interlocking interface 24 transmits / receives information regarding the status of the trains 91 and 92 and information regarding the status of the interlocking device 33 to / from the signal transmission / reception controller 23. The power supply device 34 supplies power to the signal transmission / reception controller 23.

  Moreover, you may comprise a train control apparatus by combining the ground apparatus of the structure similar to the ground apparatus 20 about the loops 110 and 112. FIG. Since the ground device combined with the loops 110 and 112 can employ the same configuration as the ground device 20, a detailed description thereof will be omitted.

  As described above, the illustrated train control device includes the loop 111. Since the loop 111 is laid along the train track, the train signal S11 is supplied from the train onboard devices 811 and 812 existing in the loop 111. For example, when there are two or more trains in the loop 111, two or more train signals S11 are supplied to the loop 111.

  The train signal S11 includes train number information of the trains 91 and 92 and train speed information of the trains 91 and 92. The train signal S11 may be an analog signal or a digital signal.

  In addition, in the train control device using the track circuit, when there are two or more trains in the block section, the train signal cannot be received due to a short-circuit of the train axle. Since it is used, such inconvenience does not occur.

  The illustrated train control device includes a ground device 20. Since the ground signal 20 is supplied with the train signal S11 via the loop 111, the train signal S11 is output based on the train number information of the train signal S11 even when two or more trains exist in the loop 111. The train can be identified. Moreover, the ground device 20 can specify the position of the train that has output the train signal S11 by time-integrating the train speed information of the train signal S11 from the time when the train enters the loop 111. Moreover, when the train signal S11 includes train position information, the ground device 20 can also specify the position of the train that has output the train signal S11 using the train position information.

  Thus, since the ground device 20 can specify the train that has output the train signal S11 and the position of the train, it can calculate the front inter-vehicle distance based on the train. Specifically, for example, the ground device 20 can set the distance to the end point of the section where the loop 111 is embedded as the front inter-vehicle distance for the foremost train 92 in the loop 111. About the back train 91, the distance with the front train 92 can be made into the front inter-vehicle distance. Similarly, when only one train exists in the loop 111, the ground device 20 can set the distance to the end point of the section in which the loop 111 is embedded as the front inter-vehicle distance.

  Moreover, since the ground device 20 can specify the speed of the train that has output the train signal S11 based on the train speed information of the train signal S11, the ground device 20 can be used for the trains 91 and 92 based on the front inter-vehicle distance and the train speed information. A stop pattern is generated, and the speed control signal S21 generated based on the stop pattern can be output to the loop 111. The speed control signal S21 is a signal used for train speed control of the on-board device, and includes, for example, speed limit information, brake notch information, and the like.

  In addition, in the train control device using the track circuit, when there are two or more trains in the block section, it becomes impossible to transmit the speed control signal due to the short-circuit of the train axle. Since it is used, such inconvenience does not occur.

  As described above, in the illustrated train control device, the ground device 20 grasps the relative positional relationship between the train existing in the loop 111 and the train ahead thereof, checks the train speed, and sets the stop pattern. Can be generated. Moreover, the ground apparatus 20 can output the speed control signal S21 to the train existing in the loop 111 and the train ahead thereof, and can control the train and the train ahead thereof. For this reason, even if two or more trains enter the loop 111, there is no possibility of a train collision, so that it is possible to perform a mobile closed operation in the loop 111.

  In the moving block operation method, since the block section is not fixed, the length of each block section can be easily changed. For this reason, the freedom degree of train control increases and it can implement | achieve shortening of the operation interval of a train, shortening of the operation time of a train, and the improvement of a train speed.

  In the illustrated train control device, a large number of trains can be operated in one loop, so that the number of loops to be used can be reduced as the entire train operation section. For this reason, the increase in equipment costs, such as a ground device provided corresponding to a loop, can be suppressed by the reduction | decrease of the number of loops.

  Further, the same configuration as that of the first and second embodiments can be applied to an automatic train operation device (ATO). Furthermore, the train control device according to the present invention described above may be partially configured by software.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, it is obvious that those skilled in the art can take various modifications based on the basic technical idea and teachings of the present invention. It is.
