Description

  The present invention relates to a train operation management system and a train operation management method.

  There is known a protective wireless system that notifies a train running around if an operator of a train finds an entry of a person or a car into a track, or if a personal injury or a derailment occurs.

  According to Patent Document 1, "in a system capable of automatically detecting the occurrence of an abnormality, erroneous recognition of the occurrence of the abnormality is reduced, and protection notification is not provided to a train which does not need to be stopped." The problem is that “an abnormality in the monitoring area is detected by performing an image analysis of the monitoring area image or moving image data acquired by the monitoring cameras 6 and 8 based on the information on the monitoring cameras 6 and 8 and the train operation status. There is described a "protected alert radio system" comprising an image control device 5 which initiates supervisory control to detect an occurrence (see abstract).

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

  FIG. 1 is a block diagram of an operation management system having a list monitor display function of a guard radio alert 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 configured by the operation rearranging device 1 that performs the process of changing the diagram by the commander when the diagram is disturbed, and the communication device 2, and the communication device A network 2 is connected to a protected wireless transmitting / receiving apparatus 3 installed at fixed distance intervals along the railway as a ground facility (on site).

  The operation rearranging device 1 is basic schedule information, such as arrival time / departure time at a station to be run, station information such as stoppage / inhibition at the station, operation information such as turning back / repeating, and real-time running results Is acquired on a train basis from the track circuit which is ground equipment, and the information is displayed on a display as a train diagram to support change input of diamonds (also referred to as operation arrangement). It also has a function to predict and display the future train schedule based on travel records.

  The communication device 2 performs transmission and reception of various information between the operation management system and the ground facility (site). The contents of the schedule change input in the operation arrangement device 1 are converted into command information that can be confirmed by the driver and the conductor, and transmitted to the train to be subjected to the schedule change. And, by displaying instruction information on the display installed on the car, a notification to the driver and the conductor is performed. The guard radio alert train 4 issues a guard radio in order to notify the train running around when an approach of a person or a car into the track is detected, or when a personal injury or a derailment occurs. . Trains that receive the guard radio are required to stop until safety confirmation is complete. This makes it possible to prevent secondary disasters in advance.

  The guard radio transmitter / receiver 3 is installed at predetermined intervals along the railway, receives the guard radio issued by the guard radio alert train 4, and communicates guard radio information including the radio ID and the train number. Send to device 2 Here, the information such as the train number and the like used in the protective wireless communication and the information identifying the individual trains used in the diagram on the operation control system side are usually configured in different formats and are not compatible. Therefore, the train number in the protected wireless information can not be used as it is in the operation control device 1. Therefore, in the present embodiment, the communication device 2 is made to possess the correspondence between both the operation diagram of the train used in the operation management system and the information such as the train number of the ground facility (site). Then, collation with the train numbers usable by the operation rearranging device 1 and conversion are performed and transmitted to the operation rearranging device 1. FIG. 2 is a process block diagram of the operation rearranging device 1 of the present embodiment. Although FIG. 2 exemplifies the configuration necessary for the present embodiment, it can be added as needed.

  As shown in FIG. 2, the operation rearranging apparatus 1 includes a CPU 200, a memory 210, and a display 140. In the memory 210, a schedule diagram for predicting future train operation based on an execution diagram that is an operation plan of a train, a performance diagram that is a travel result of a train acquired from the ground facility, and a performance diagram as a diagram information database 100 It holds. Further, the diagram information database 100 reflects the contents processed in the diagram change processing 110 for changing the diagram based on the travel record / presence of the train and the input information on the operation arrangement.

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

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

  The display 140 displays various diamonds created by the train line display processing 130, and also displays the location where the protective radio is notified, the influence range thereof, and the like. The display content of the display 140 will be described later.

  Further, it is possible to perform screen operation processing 150 for receiving an input of enlargement / reduction or movement of a screen or change of a diagram on the display 140 by an input device such as a mouse or a keyboard (not shown). The input of the diamond change accepted by the screen operation processing 150 is processed in the diamond change processing 110 and reflected in the diamond information 100.

  FIG. 3 shows an outline of a processing flow of train number collation processing in the communication device 2 of this embodiment.

  First, the communication device 2 starts train number collation processing in 2000, using the reception of the protected wireless information from the protected wireless transmitting / receiving device 3 as a trigger. At 2100, the received protected wireless information is expanded in the communication device 2. The communication device 2 stores the correspondence between the train number managed by the guard radio and the train number managed by the operation management system, and in 2200, performs data check of the train number collation request. Specifically, the train number in the received protected wireless information is present on the operation diagram of the operation management system owned by the communication device 2, and the train number in the received protected wireless information is not It is checked whether it is included in the target line segment, and in the case of no processing, the train number collation processing is ended. Also, when the train number collation is completed at the time of reception, the train number collation processing is ended as processing no. If the processing is necessary, train number collation is performed in 2300. The operation information management system 1 compares the information of the train number, the running line zone, and the existing station with the protected wireless information and the train information of the implementation diagram held by the communication device 2 and when all the information match, As train numbers that can be used in When the collation is completed in 2400, the train number for which the guard radio has been issued is converted to a usable train number in the operation management system and notified to the operation management device 1. In the case of non-coincidence, the protective wireless information of interest is determined as verification NG at 2500, and after transmitting command information indicating that the verification is NG on the vehicle, the protective wireless information is discarded at 2600. When the driver / passenger confirms the collation NG, the verbal communication with the commander is required as in the past. Here, it is assumed that collation NG is not transmitted during data recovery at the time of startup of the communication device 2, and the train number collation processing 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 outline of the processing flow of the train stripe display processing of the operation rearranging device 1 of the present embodiment and the list monitor display function in the screen operation processing.

  First, the operation rearranging device 1 starts processing of the list monitor display function at 1000, triggered by the reception of the train number (hereinafter referred to as a notification train) that has issued a protective radio from the communication device 2 (hereinafter referred to as a notification train). At 1100, the received alerting train is deployed in the operation control device 1. At 1200, from the notification trains, the affected radios are checked out by protective radio, and the degree of risk is judged for each train.

  Specifically, based on the location of the alert train, it is determined that the train existing within the range of the predetermined distance is the affected train. Then, the forecasting diagram and the traveling results / presence of the train in the diagram information database 100 are searched, and a list of trains in the vicinity of the reporting train, that is, within a predetermined range is created. More specifically, as described later with reference to FIG. 5, the influence range is drawn in a semicircular shape on the diagram display screen on the basis of the location of the alert train, and the influence range and the implementation diagram, or the forecast diagram at that time The overlapping trains are judged to be affected by protective radio, and a list of these trains is made.

  Next, for the trains in the list, the degree of danger is calculated from the traveling order based on the reporting train. The traveling order is determined on the forecasting diagram from the traveling line divisions and lines and the arrival time / departure time of each station. In particular, it is judged that the danger level of the latest following train is high for the reporting train. In addition, compare the report train with the line segment and the line segment, and in the case of the same line segment and the same line segment, judge that the risk is high. However, if there is a possibility that problems will occur even in a different track or in a different track section depending on the line alignment, the trouble range is incorporated in advance in operation arrangement 1 with a constant and added as a judgment item.

  Furthermore, for each train, after calculating the degree of danger, we propose the operation arrangement according to the degree of danger. Normally, trains that receive protective radios are prevented from leaving to prevent secondary damage. Thus, for example, in the case where the degree of danger is high and it is necessary to suppress traveling in an emergency, "departure suppression" is proposed to suppress train traveling. In addition, when the safety of the site is secured, the "departure suppression" is canceled. However, it is necessary to adjust the time interval with which the preceding train travels for trains traveling backward from the reporting train. Therefore, for example, in the case of a train with a low degree of risk, we propose "extension" to adjust the interval between trains. After the above process is completed, monitor information editing 1300 is performed to edit the information of train number, existing line position, degree of risk, wireless number and operation 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 is performed to change the color of the influence range on the display. Also about the influence range which changes color, it incorporates in the operation rearranging apparatus 1 by a constant beforehand. The 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 view showing an example of a screen of the display 140 of the present embodiment. On the display 140, the vertical axis is the station (distance), and the horizontal axis is the time, and the actual time chart and the predicted time chart are displayed. The operation rearranging device 1 displays the vicinity of the guard radio alert train received from the communication device 2 as a dark semicircle with a color change in the train line display processing 130 so that the guard radio alert point can be grasped immediately. . Then, the range affected by the protective radio alert is displayed as a light semicircle with a color change, and the range of influence can be grasped immediately. An example of screen display in a protective wireless alert is shown at 1600. Here, in the operation rearranging device 1 of the line ward where the alert train does not exist, a pale semicircle is displayed by defining the display range of the operation rearranging device 1 corresponding to the line ward / station of the alerting train with a constant Make a decision on what to do. In addition, the operation rearranging device 1 displays various stations and line screens for each line section, and in some cases, may display only a part of a semicircle. A display example in the case of displaying only a part of a semicircle is shown in 1700.

Further, in the screen operation processing 150, by clicking on the color change portion, the related train, the location on the track, the degree of danger, the wireless number, and the operation arrangement proposal are displayed on a monitor. The monitor display contents are shown in 1800.
The monitor display shows the name and location of the alert train, the location and radio number of the alert train, and the name of the related train affected by the alert and the location, risk, radio number, and operation control plan of each location. . In this way, by displaying the high risk trains at the top, it is possible to determine the priority of the trains that need to be communicated. With regard to a train which has been communicated by radio and a train whose safety confirmation has been completed and which has started traveling, only necessary information is always displayed by deleting it from the monitor display. As an example, at 1800, the monitor display contents in a state in which the train B and the train C have been contacted are shown at 1900.

  Thus, with the operation management system of this embodiment, it is possible to quickly confirm the influence range after the protective wireless notification and secure the transport amount.

  According to this embodiment, for example, when applied to a device that displays train schedule screen and performs operation arrangement input, it becomes possible to display the influence range of protective wireless on the train diagram, so only the operation arrangement input device is seen The contents of the drive arrangement can be determined, and the input mistake of the drive arrangement can be prevented and the input of the drive arrangement requiring an emergency can be realized.
