  In a train operation management system, when a schedule disruption occurs due to various factors such as a natural disaster, a vehicle failure, or a personal accident, it may be necessary to change a planned schedule. In such a case, the commander inputs a schedule change from a device that manages the train operation, and performs a schedule change called operation arrangement.

  Here, in patent document 1, the automatic protection radio alerting | reporting by the surveillance camera is implement | achieved, It is necessary to stop by issuing the protection radio alert only for the specific train which approachs the surveillance area. It is possible to stop only the train. However, the impact on the diamond caused by issuing the protection radio cannot be grasped on the operation management system that inputs the diamond change. Therefore, as in the past, the commander had to check the status of the train stopped by receiving the protection radio notification by using the radio and change the timetable.

  The present invention relates to a train operation management system, and when a protection radio is issued, it is easy for a commander to grasp the location of the protection radio and the range of influence, and assists in confirming the status of nearby nearby trains. Thus, an object of the present invention is to provide a train operation management system and an operation management method having a function of supporting transportation volume securing.

  In order to solve the above problem, one of the train operation management systems and the like according to the present invention obtains protective radio information issued from a train when an abnormality is detected, and the protective radio information is obtained from the protective radio information. Identifying the identification information of the train reporting the protection radio that issued the alarm, and using the identification information of the identified train reporting the protection radio, from the on-line information of a plurality of operating trains taken from the ground equipment, the protection radio It is characterized in that the on-line position of the reporting train is obtained, the range of influence by the protective radio reporting is obtained from the on-line position of the protective radio reporting train, and displayed on the display.

  An embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a configuration diagram of an operation management system having a list monitor display function of a protection radio alarm train and nearby trains according to an embodiment of the present invention. As shown in FIG. 1, the operation management system of the present embodiment is composed of an operation arrangement device 1 that performs a timetable change process by a commander when a timetable is disrupted, and a communication device 2. 2 is connected to the protective radio transmission / reception apparatus 3 installed at regular intervals along the railway as a ground facility (local site).

  The operation control device 1 is basic schedule information, such as arrival / departure time at the station where the vehicle travels, station information such as suspension / deterrence at the station, operation information such as loopback / relay, and real-time travel results. Is obtained for each train from the track circuit, which is a ground facility, and the information is displayed on the display as a train diagram diagram, thereby assisting in the diagram change input (also referred to as operation arrangement). It also has a function to predict and display future train schedules based on the running results.

  The communication device 2 transmits and receives various information between the operation management system and the ground equipment (site). The contents of the schedule change input by the driving arrangement apparatus 1 are converted into command information that can be confirmed by the driver / conductor and transmitted to the train to be changed. Then, the command information is displayed on the display installed on the vehicle to notify the driver / conductor. Protective radio alarm train 4 issues a radio alarm to notify the trains that run around when a person or vehicle enters the track, or when a person accident or derailment occurs. . The train that has received the protection radio is obliged to stop until the safety check is completed. Thereby, a secondary disaster can be prevented beforehand.

  The protection radio transmission / reception device 3 is installed along the railway at regular distance intervals, receives the protection radio issued by the protection radio notification train 4, and communicates the protection radio information including the radio ID and the train number. Transmit to device 2. Here, the information such as the train number normally used in the protection radio and the information for identifying individual trains used in the schedule on the operation management system are configured in different formats and are not compatible. Therefore, the train number in the protection radio information cannot be used as it is in the operation arranging device 1. Therefore, in the present embodiment, the communication device 2 has a correspondence relationship between the operation schedule, which is a train operation plan used in the operation management system, and information such as the train number of the ground facility (site), and the communication device 2 Then, the train number that can be used in the operation arranging device 1 is collated and converted, and transmitted to the operation arranging device 1. FIG. 2 is a processing block diagram of the operation arranging apparatus 1 of the present embodiment. Although FIG. 2 illustrates the configuration necessary for the present embodiment, it can be added as necessary.

  As shown in FIG. 2, the driving arrangement apparatus 1 includes a CPU 200, a memory 210, and a display 140. In the memory 210, an execution diagram that is a train operation plan, a track diagram that is a running record of a train acquired from the ground facility, and a prediction diagram that predicts a future train operation based on the track diagram is used as a diagram information database 100. I have it. Further, the diagram information database 100 reflects the contents processed by the diagram change processing 110 for changing the diagram based on the train traveling results / present line status and the input operation arrangement information.

  FIG. 6 is a diagram showing a data format of the diagram information database 100. Here, it is assumed that the format of the implementation diagram, the performance diagram, and the prediction diagram are all common. In the diamond format 600, items included in the diamond format for each serial number in the traveling direction in the vertical direction are shown. The diamond format 600 includes information that describes the arrival time of each station in the traveling direction or the departure time from each station for each train. Each train is identified by train number 610.

  Returning to FIG. 2, the processing performed by the CPU 200 will be described. The CPU 200 accepts the input of the operation arrangement by the commander, and changes the timetable 110 for changing the timetable, the train line data creation process 120 for creating the train line data based on the information in the timeline information database 100, and the generated train line data. Train streak display processing 130 for performing processing for displaying the information on the display 140.

  The display 140 displays various diagrams created by the train streak display processing 130, and also displays the location where the protection radio is issued, the range of influence thereof, and the like. The contents displayed on the display 140 will be described later.

  Further, a screen operation process 150 for accepting an input of screen enlargement / reduction, movement, or diagram change on the display 140 can be performed by an input device such as a mouse or a keyboard (not shown). The input of the diamond change accepted by the screen operation process 150 is processed by the diamond change process 110 and reflected in the diamond information 100.

  FIG. 3 shows an overview of the processing flow of the train number matching process in the communication device 2 of the present embodiment.

  First, the communication device 2 starts the train number verification process in 2000 using the reception of the protection wireless information from the protection wireless transmission / reception device 3 as a trigger. In 2100, the received protection radio information is expanded in the communication device 2. The communication device 2 stores a correspondence relationship between the train number managed by the protection radio and the train number managed by the operation management system. In 2200, the data check of the train number verification request is performed. Specifically, the train number in the received protection radio information is present on the operation schedule of the operation management system owned by the communication device 2, or the train number in the received protection radio information is the communication device 2 A check is made as to whether it is included in the target line section, and if the processing is not possible, the train number matching process is terminated. Also, when the train number verification is completed at the time of reception, the train number verification process is terminated as a processing failure. If processing is required, train number verification is performed at 2300. When the protection radio information and the train information of the timetable of the communication device 2 are compared with each other, the train number / running line / station information is compared. As a train number that can be used in When the verification is completed in 2400, the train number that issued the protection radio is converted into a train number that can be used in the operation management system, and notified to the operation arranging device 1. If they do not match, the target protection radio information is determined to be verification NG at 2500, command information notifying that the verification is NG on the vehicle is transmitted, and then the protection radio information is discarded at 2600. If the driver / conductor confirms the verification NG, it is necessary to verbally contact the commander as before. Here, it is assumed that the verification NG is not transmitted during data recovery when the communication device 2 is started up, and the train number verification process is executed again after the data recovery. As described above, the train number verification process is completed, and the process ends at 2700.

  FIG. 4 shows an overview of the processing flow of the list monitor display function in the train stripe display process and the screen operation process of the operation arranging device 1 of the present embodiment.

  First, the operation arrangement device 1 starts processing of the list monitor display function at 1000, triggered by reception of a train number (hereinafter referred to as a notification train) that has issued a protection radio from the communication device 2 as a trigger. In 1100, the received notification train is deployed in the operation arrangement apparatus 1. In 1200, the train affected by the protection radio is identified from the reporting train, and the risk is determined for each train.

  Specifically, a train that is present within a predetermined distance range is determined to be an affected train with reference to the position of the existing train. Then, the prediction diagram and the running record / present line state in the diagram information database 100 are searched, and a list of trains that are in the vicinity of the reporting train, that is, within a predetermined range, is created. More specifically, as will be described later with reference to FIG. 5, the influence range is drawn in a semicircular shape on the diagram display screen with reference to the position of the informing train, and the influence range and the execution diagram, or the prediction diagram at that time are Overlapping trains are judged to be affected by the protection radio, and a list of these trains is created.

  Next, for the trains in the list, the degree of risk is calculated from the traveling order based on the reporting train. The traveling order is determined on the prediction diagram based on the line segment / line to be traveled and the arrival time / departure time of each station. In particular, it is determined that the risk level of the latest train is higher than that of the reporting train. Further, the reporting train is compared with the line and line, and in the case of the same line and line, it is determined that the degree of risk is high. However, for locations where there is a possibility that troubles may occur even in different lines or different lines depending on the alignment of the track, the trouble range is incorporated into the operation arrangement 1 in advance with constants and added as a determination item.

  Furthermore, after calculating the degree of danger for each train, a proposal for operation arrangement according to the degree of danger is made. Normally, trains that receive a protection radio are prevented from departing to prevent secondary damage. In this way, for example, when the degree of danger is high and it is necessary to suppress travel in an emergency, “departure suppression” that suppresses train travel is proposed. In addition, when on-site safety is ensured, “departure prevention” is canceled. However, it is necessary to adjust the travel time interval of the train behind the reporting train with respect to the earlier train. For this reason, for example, for trains with a low degree of danger, a “delay” is proposed in which the travel interval of the train is adjusted. After the above processing is completed, monitor information editing 1300 is performed to edit information on the train number, existing line position, degree of danger, radio number, and driving arrangement proposal as information to be displayed in the list monitor.

  After the editing of the monitor information is completed, a screen display update process 1400 for changing the influence range on the display is performed. The range of influence for color change is also incorporated in the operation arranging apparatus 1 with a constant in advance. Details of the screen display are shown in FIG. As described above, the process of the list monitor display function is completed, and the process ends at 1500.

  FIG. 5 is a diagram illustrating a screen example of the display 140 according to the present embodiment. On the display 140, a station diagram (distance) is displayed on the vertical axis, and a timetable and prediction diagram are displayed on the horizontal axis as time. In the train line display processing 130, the operation arrangement device 1 displays the vicinity of the protective radio notification train received from the communication device 2 in a dark semi-circle that has been color-changed so that the location of the protective radio notification can be immediately grasped. . The range affected by the protection radio alarm is displayed in a pale semi-circle whose color has been changed, so that the range affected can be immediately grasped. A screen display example in the protection radio alarm is shown in 1600. Here, in the operation arranging device 1 of the line section where the reporting train does not exist, a light semicircle is displayed by defining the display range of the operation arranging device 1 corresponding to the line / station of the reporting train by a constant. Judge whether to do. In addition, the operation organizing apparatus 1 displays a screen along with various stations for each line section. In some cases, only a part of a semicircle may be displayed. An example of display when only a part of the semicircle is displayed is shown in 1700.

In addition, by clicking on the color change part in the screen operation processing 150, the related train, existing line position, degree of danger, radio number, and driving arrangement proposal are displayed on the monitor. The monitor display contents are shown at 1800.
The monitor display shows the train name, existing track position and radio number of the reporting train, as well as the train name of each related train affected by the report, each track location, risk level, radio number, and operation arrangement plan. . Thus, it becomes possible to judge the priority of the train which needs to be contacted by displaying the train with a high risk level on the upper part. For trains that have been contacted by radio or for trains that have completed safety checks and have started running, the train display is erased so that only necessary information is always displayed. As an example, 1900 shows monitor display contents in a state in which contact with train B and train C is completed at 1800.

  As described above, the operation management system according to the present embodiment can quickly confirm the range of influence after issuing the protective radio and ensure the transportation amount.

  According to the present embodiment, for example, when applied to an apparatus that displays a train diagram screen and performs operation adjustment input, it is possible to display the range of influence of the protection radio on the train diagram. It is possible to determine the contents of the operation arrangement, and it is possible to prevent an input mistake in the operation arrangement and to input an operation arrangement that requires an emergency.
