Description

  The present invention relates to a train operation management system.

  In metropolitan areas such as high-density operation lines and bullet trains, train operation management systems have been introduced to improve the efficiency of train operation management and improve passenger services. In the train operation management system, there is a central command room that manages the operation of trains on a given route. In this central command room, when there is an abnormality such as a central device that manages train schedules, train delays, etc. There will be an operation console that gives commands for operation control such as train schedule changes to the central unit, and an operation display panel that displays the operation status of trains on the above routes.

  Each station on the route is provided with a station control device that receives a train schedule from a central device via a network, and a train information device connected to the station control device. The train information device receives the identification information of the train that has passed through the ground element from the ground element arranged on the track and sends it to the station control apparatus. The station control device controls the operation of various devices based on the train identification information sent from the train information device and the train diagram above, and the station control device installed at the interlocking station is a train arrival guide. In addition to performing departure guidance and the like, the operation of the interlocking device installed in the interlocking station is controlled according to the train schedule.

  The above interlocking device controls the operation of field equipment such as a switch device, a signal device, a sign device, and a display device under a predetermined interlocking condition to configure a predetermined train route for each train, and a train information device Also controls the operation of railroad crossings. In order to allow the station control device to accurately control the operation of the interlocking device according to the train schedule, multiple track circuits are installed on the track to track the train. A car carrier for sending is installed. The train identification information transmitted from the vehicle top is received by the above-mentioned ground unit, sent to the train information device, and from here to the station control device. The station control device identifies a train that has passed the above-mentioned ground element based on the identification information, and controls the interlocking device based on the information obtained from the train diagram and the track circuit to configure a predetermined train route. .

  In this way, under the train operation management system, the train route at the interlocking station is automatically configured according to the train schedule. For example, the function of the station control device at a certain interlocking station temporarily stops due to a power failure or the like. When the train route cannot be automatically configured, the worker manually operates the field equipment to configure the train route and operate the train. Therefore, the train schedule is changed. However, distribution of the train schedule after the change to the station control device cannot be performed until the station control device is restored.

  In addition, even after the station control device is restored, in order to automatically control the configuration of the train route by the station control device, it is necessary to specify in advance each train being operated and the position of the existing track. . Identification of each train and its line location after the station controller has been restored has been done by contacting the crew about all the trains in operation and confirming the identification information and line location verbally. This identification takes a relatively long time.

  Patent Document 1 describes an automatic diamond arrangement device that can arrange a train diagram in accordance with the actual train operation in a shorter time when the train operation management device is launched during the operation of the train. Yes. In this automatic timetable arrangement device, the train operation management device tracks each train based on the display information of the field input from the interlocking device, and when each train is being tracked, it is transmitted from the ground unit installed in the station premises. By searching the train schedule of each train by the operation number input to the train operation management device via the device, the train operation management device seeks the train diagram corresponding to the input operation number, and assigns the train number. Organize train schedules at each station.

Japanese Patent No. 3089240

  Since the automatic diamond arrangement device described in Patent Document 1 is a device that allows a train number to be assigned to a train for the first time when the ground unit installed in the station receives the operation number from the train, It may take a long time before the train number can be assigned. As a result, it may take a long time for the station control device to recover from the temporarily stopped state and to automatically control the configuration of the train route by the station control device.

  The present invention has been made in view of the above circumstances, and it is possible to automatically control the configuration of the train route by the station control device when the function of the station control device is recovered from a temporarily stopped state. It aims at obtaining the train operation management system which is easy to shorten the time to the time.

An interlocking panel that manually controls the train is installed, and train tracking is performed by identifying the travel position of the train using the station controller based on the information on the railroad and fall of each of the multiple track circuits installed on the track of the route. In the train operation management system, in the vicinity of the train entry part in the management range where the station control device tracks the train, a ground unit that receives the train number information of the passing train from the train and transmits it to the train information device. Arrangement When the station control device of the interlocking station temporarily stops and the operation of the station control device needs to be organized, the train schedule changed from the central device after the restoration of the station control device Based on the train number information transmitted from the ground unit to the train information device and the changed train diagram while the operation of the field equipment is manually controlled by the interlocking panel and the train is operated The train number of the train that has passed the ground unit is confirmed, and only the train with the train number confirmed is in the management range, and the interlocking device starts automatic control of field equipment. It is.

  In the train operation management system according to the present invention, the ground unit is arranged in the vicinity of the train entry part in the management range by the station control device, and train number information is received from the train by the ground unit and transmitted to the train information device. Compared with the case where a ground element having the above function is installed in the station premises, it is easy to shift to a state where only the train whose train number is determined is in the management range in a relatively short time. As a result, according to the train operation management system of the present invention, when the function of the station control device is recovered from a temporarily stopped state, the configuration of the train route can be automatically controlled by the station control device. It becomes easy to shorten the time.

Become. Information on the fall of each track circuit is transmitted to the interlocking device 21 even when the operation of the field device 25 is manually controlled by the interlocking panel 27, and is transmitted from the interlocking device 21 to the station control device 20. .

FIG. 3 is a flowchart schematically illustrating an example of a procedure that is performed until the station control device of the interlocking station starts automatic control of the field device when the train schedule is changed for operation control. It is. In step S1 first performed in the illustrated example, the central device 1 distributes the train schedule changed in accordance with the operation arrangement to each station control device 20 via the network NW ₃ (see FIG. 1).

  Next, in step S <b> 2, the train number information TN (see FIG. 1) is obtained from the upper element of the train that is installed in the vicinity of the train entry portion in the management range of the station control device 20. The train number information TN is received and transmitted to the train information device 23. That is, the train information device 23 receives the train number information TN from the above-mentioned ground unit. At this time, the train passing through the above-mentioned ground element is a train that is operated by manually controlling the operation of the field device 25 (see FIG. 1) by the interlocking panel 27.

  In step S3, the station control device 20 receives the train number information TN from the train information device 23. The train number information TN is transmitted to the train tracking unit 15 (see FIG. 2) of the station control device 20. In step S4, the station control device 20 receives information about the operation status of the field equipment 25 (field information) from the interlocking device 21 (see FIG. 1), and information related to falling on the track circuit and falling is linked to the interlocking device 21. Receive from. These pieces of information are also transmitted to the train tracking unit 15 of the station control device 20.

In step S5, the train tracking unit 15 that has obtained the above information obtains the travel position of the train that has transmitted the train number information TN based on the information, and is stored in the diagram storage unit 13 (see FIG. 2). Column number setting processing for determining the train number of the train for which the travel position is obtained based on the train schedule after the change and the train number information TN obtained in step S3, and associating the train travel position with the train number. Do. Information on each of the train travel position and train number used in the row number setting process in step S5 is sent to the route control unit 17 (see FIG. 2) and is also displayed on the operation display board 5 (FIG. 1) via the network NW ₃ . See). As described above, the operation display board 5 that has obtained the information displays the train number on a predetermined display window among a plurality of display windows indicating the traveling position of the train on the route.

  On the other hand, the route control unit 17 creates in advance train entry sequence data and departure sequence data at its own station based on the train schedule after the change stored in the diagram storage unit 13, and the train tracking unit 15 (refer to FIG. 2), when the train information whose train number is determined in step S5 is obtained, the order of entry of the train to its own station is changed to the above information and the train schedule after change stored in the diagram storage unit 13. Step S6 is specified based on the above. Moreover, following this step S6, step S7 which specifies the departure order from the own station is performed.

In step S6 described above, for example, conceptually shown in FIG. 4, the order of entry of the train whose train number has been determined in step S5 to its own station is set to “first”, and the approach course is configured at the earliest time. A pointer (hereinafter referred to as “head pointer”) P ₁ indicating a train to be performed is controlled to be matched with the train in the approach sequence AO. Further, in step S7, for example, conceptually shown in FIG. 4, the train in which the advancing route is to be formed at the earliest time in the departure order sequence DO is specified based on the train schedule after the change, and the departure order is determined. adjust the head pointer P ₂ on the train in a row. In addition, the approach sequence row AO and the departure sequence row DO are respectively created using train numbers.

  By performing steps S1 to S7 described above, the station control device 20 determines the train that should form the approach route and the departure route at the earliest time, but the train operation management system 50 (see FIG. 1) ensures safety. From the point of view, the on-site equipment 25 (by the interlocking device 21 under the control of the station control device 20) until only the train whose train number is fixed is in the management range of the station control device 20 The automatic control (see FIG. 1) is not started.

  For this reason, following step S7 described above, step S8 is performed in which the station control device 20 determines whether or not only the train whose train number is determined is in the management range. For example, the saddle, the fall information obtained from the interlocking device 21, the train number information TN received by the train information device 23, and the changed train diagram stored in the diagram storage unit 13 (see FIG. 2). If it uses, it can be judged whether only the train by which the train number was decided exists in said management range.

  If it is determined in step S8 that a train whose train number is not confirmed is in the management range, the process returns to step S2, and if only a train whose train number is confirmed is determined to be in the management range, the process proceeds to step S9. The station control device 20 causes the interlocking device 21 to start automatic control of the field device 25.

  In addition, the automatic control of the field device 25 by the interlocking device 21 may be started simultaneously on the track for the up train and the track for the down train, or may be started at different times. When the automatic control of the field device 25 by the interlocking device 21 is started at different times for the ascending train and the descending train, only the train whose train number is determined is in the management range. In step S8, it is determined separately whether or not the management range for the upstream train and the management range for the downward train.

  In the train operation management system 50 that manages the train operation as described above, a ground unit is arranged in the vicinity of the train entry part in the management range by the station control device 20, and the train number information TN is transmitted from the train by the ground unit. Since it is received and transmitted to the train information device 23, it can be compared with a state in which only the train whose train number is determined is in the above-mentioned management range, compared with the case where a ground unit having a similar function is installed in the station premises. Easy to move in a short time. As a result, according to the train operation management system 50, it is possible to automatically control the configuration of the train route by the station control device 20 when the function of the station control device 20 is recovered from a temporarily stopped state. It is easy to shorten the time to become.

  The train operation management system according to the present invention has been described with reference to the embodiment. However, as described above, the present invention is not limited to the above-described embodiment. For example, if the ground unit that receives train number information from the train upper part of the train and transmits it to the train information device is installed in the vicinity of the train entry part in the management range where the station control device tracks the train, its installation The total number of locations can be selected as appropriate. For example, in addition to the vicinity of the train approaching portion, a ground unit having the above function can be installed in a station premises or just before a control start point where the station control device controls the operation of the interlocking device. If a plurality of ground elements are installed in this way, it becomes possible to shift to a state where only the train whose train number is determined is in the above-mentioned management range in a shorter time.
