Description

Technical Field

[0001] The present invention belongs to the technical field of train display, and in particular, relates to a short route display method, system, device and medium for group train control. Background Art

[0002] The group train operation control system is developed from virtual marshaling technology. It is based on low-latency vehicle-to-ground and vehicle-to-vehicle wireless communications. By coordinating the distance and speed of trains and controlling and managing marshaling and disassembling, it increases the flexibility of group train marshaling and reduces human intervention, thereby shortening the train running interval, saving labor costs and transportation resources, and improving the utilization rate of station lines.

[0003] In order to adapt to the technical requirements of the group train marshaling and disassembling, the station computer interlocking system needs to introduce short routes and virtual signal displays in the station map interface of the control and display machine, so that the train staff can always monitor the operation status of the group trains in the station. A short route is a train route arranged for group trains. It can be composed of one or more track sections and is used to control the operation of group trains. A virtual signal is a special signal displayed on the station map interface. Its purpose is to serve as the starting point or end point of a short route, so that the centralized dispatching system (CTC) can issue short route arrangement commands.

[0004] Due to the particularity of short routes, virtual signals do not correspond to outdoor signal machines, and train personnel are not allowed to operate virtual signals or arrange short routes on the control and display machine. In addition, the larger the scale of the station, the more possible combinations of short routes there are, and the more virtual signals need to be drawn on the station map. In the group train control system, the centralized dispatching system (CTC) needs to issue a short route arrangement command, and then the computer interlocking system (CBI) executes the short route processing and displays it through the station map interface of the control and display machine. However, there is currently no function for drawing virtual signals and short routes in the station map of the control and display machine.

[0005] The present invention provides a short route display method, system, device and medium for group train control, which provide train maintenance personnel with a display of short route arrangement and section occupancy and clearance status of group trains on a station diagram interface. Summary of the invention

[0006] The purpose of the present disclosure is to provide a short route display method, system, device and medium for group train control in order to solve the above problems.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions: A short route display method for group train control comprises the following steps: Add virtual signals in the section where short routes can be arranged. When the short route is successfully established and the virtual signal is used as the starting point of the short route, the virtual signal is drawn on the station diagram, otherwise the virtual signal is hidden on the station diagram; When a track section is occupied by a group train or a non-group train, the occupied track section is drawn as a corresponding light band of a different preset color on the station map.

[0008] As a further optimization solution of the present disclosure, when the short route is successfully established and the virtual signal is used as the starting end of the short route, the virtual signal is drawn on the station map, otherwise the virtual signal is hidden on the station map, including: When the short route is established successfully and the route starting signal is a virtual signal, the control interlocking host sends the virtual signal to the control and display machine as a mark of the starting end of the short route. After receiving this mark, the control and display machine draws the virtual signal; for the virtual signal that is not the starting end of the short route, the control and display machine does not draw this signal on the station diagram.

[0009] As a further optimization scheme of the present disclosure, when the starting point of the short route is a virtual signal and the short route section where the virtual signal is located is unlocked, the control and display machine receives from the interlocking host that the virtual signal is no longer a sign of the starting point of the short route, refreshes the station field map and hides the virtual signal.

[0010] As a further optimization scheme of the present disclosure, the short route section unlocking includes the unlocking of group train occupancy clearance, the unlocking of the manual unlocking command or the zone fault unlocking command issued by the centralized dispatching system CTC.

[0011] As a further optimization solution of the present disclosure, the status of the track section includes idle, group train occupied, non-group train occupied and section locked, all of which are displayed in different preset colors.

[0012] As a further optimization scheme of the present invention, the control and display machine sends synchronous data related to the virtual signal to the centralized dispatching system CTC, including the color light status of the virtual signal, the switch light mark, the mark of whether it is closed due to a fault, the mark of whether it is the beginning of a short route, the mark of whether its train button is flashing, the mark of whether the train button is closed, and the countdown delay information.

[0013] As a further optimization solution of the present disclosure, a flag indicating whether a track section is occupied by a group train is sent to the dispatching centralized system CTC through the control and display machine. A short route display system for group train control, comprising: A virtual signal display module is used to add a virtual signal in a section where a short route can be arranged. When the short route is successfully established and the virtual signal is used as the starting end of the short route, the virtual signal is drawn on the station map, otherwise the virtual signal is hidden on the station map; The section occupancy display module, when the track section is occupied by a group train or a non-group train, the occupied track section is drawn as a corresponding light band of different preset colors on the station map.

[0015] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements a short route display method for group train control.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] like Figure 1 As shown, a short route display method for group train control includes the following steps: Add a virtual signal to the section where the short route can be arranged. When the short route is successfully established and the virtual signal is used as the starting point of the short route, the virtual signal is drawn on the station map, otherwise the virtual signal is hidden on the station map. Specifically, when the short route is successfully established and the route starting point signal is a virtual signal, the interlocking host sends the virtual signal to the control and display machine as a mark of the starting point of the short route. The control and display machine draws the virtual signal only after receiving this mark. For virtual signals that are not the starting point of the short route, the control and display machine does not draw this signal on the station map. When the starting point of the short route is a virtual signal, and the short route section where it is located is unlocked (including unlocking of group train occupation and clearance, unlocking of human release command or zone fault release command issued by CTC), the control and display machine will refresh the station map drawing and hide the virtual signal after receiving from the interlocking host that the virtual signal is no longer a mark of the starting point of the short route.

[0020] When a track section is occupied by a group train or a non-group train, the occupied track section is drawn as a corresponding light band of different preset colors on the station map, specifically including: when the track section is occupied by a group train, the control and display machine draws the section as a light pink light band on the station map; when the track section is occupied by a non-group train, the control and display machine draws the section as a red light band on the station map. The computer interlocking system sends the following virtual signal-related synchronization data to CTC through the control and display machine: the color light status of the virtual signal, the switch light mark, the mark of whether it is closed due to a fault, the mark of whether it is the beginning of a short route, the mark of whether its train button is flashing, the mark of whether the train button is closed, and the countdown delay information. The computer interlocking system sends the mark of whether the track section is occupied by a group train to CTC through the control and display machine.

[0021] The short route display method for group train control proposed by the present invention has the following characteristics: 1. Short route is a special train route for group train arrangement, which can only be handled with train signals as the starting and ending points.

[0022] 2. Short routes can be composed of one or more sections. The diversity of short route arrangements and combinations directly affects the flexibility of group train formation. The existing train signals at the station include entry signals and exit signals. Due to the limited number of train signals, virtual signals need to be added at both ends of the section where short routes can be arranged.

[0023] 3. The starting signal of the short route is displayed as a light-off signal, that is, a cross is drawn on the signal light circle. When a virtual signal is used as the starting point of the short route, the virtual signal is drawn on the station diagram, otherwise the virtual signal is hidden on the station diagram.

[0024] 4. Conventional train routes support manual operation on the control and display interface, so there is a train signal button next to the train signal. However, since the arrangement of short routes can only be handled by the dispatching centralized system (CTC) issuing an arrangement command, it does not support manual operation on the control and display interface, so the train signal button is not drawn next to the virtual signal.

[0025] 5. When drawing a section occupied by a train, in order to distinguish between group trains and non-group trains, the group control center (GCC) sends the group train logo to the computer interlocking system, and the control and display machine draws the section light band occupied by the group train as a light pink light band. The status meanings corresponding to the section light band colors are shown in Table 1.

[0026] Table 1 Segment status display description table

[0027] 6. The computer interlocking system sends the following virtual signal-related synchronization data to CTC through the control and display machine: the color light status of the virtual signal, the switch light mark, the mark of whether it is closed due to a fault, the mark of whether it is the beginning of a short route, the mark of whether its train button is flashing, the mark of whether the train button is closed, and the countdown delay information.

[0028] 7. The computer interlocking system sends a signal to CTC via the control and display machine to indicate whether the track section is occupied by a group train.

[0029] In this embodiment, the arrangement, occupation and clearance drawing process of the short route proposed in the present disclosure is as follows: (1) Figure 6 As shown in the figure, in order to arrange the short route through the non-branched section IIBG, virtual signals V2 and V4 are added at one end. In the figure, S is the entry signal, and XII is the exit signal. The side from S to V2 is the upward direction, and the side from XII to V4 is the downward direction.

[0030] (2) Figure 7 It is the interface for controlling and displaying the station map. Figure 6This is consistent with the station reversal. At this time, virtual signals V2 and V4 do not become the start signals of the short route, so they are hidden on the station diagram interface.

[0031] (3) Take a short route in the down direction of a group train as an example. Figure 8 As shown in the figure, CTC issues short route arrangement commands from XII to V2 and V4 to S respectively. The computer interlocking system receives the command and handles the short route locking and opening signal. At this time, V4 is the starting point of the short route, and the open signal is displayed on the station map. The IIBG section is a white locked light strip, indicating that the IIBG is free at this time and the train can enter the section.

[0032] (4) If Fig. 9 When the train completely enters the IIBG, the section displays the pink light band occupied by the group train. At this time, the virtual signal V4 is still the short route V4 to the beginning of S, and a prohibition signal is displayed, indicating that the rear vehicles are prohibited from crossing V4 and entering the IIBG section.

[0033] (5) When the group train completely leaves the IIBG section, the short route V4 to S is unlocked, and the virtual signal V4 is no longer the start of the short route, so V4 is no longer displayed. Fig.10 shown.

[0034] like Fig.11 As shown, an embodiment of the present disclosure provides a short route display system applied to group train control, comprising: A virtual signal display module 11 is used to add a virtual signal in a section where a short route can be arranged. When the short route is successfully established and the virtual signal is used as the starting end of the short route, the virtual signal is drawn on the station map, otherwise the virtual signal is hidden on the station map; The section occupancy display module 12 draws the occupied track section as a corresponding light band of different preset colors on the station map when the track section is occupied by a group train or a non-group train.
