Detailed ways

The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the related invention, but not to limit the invention. In addition, it should be noted that, for the convenience of description, only the parts related to the invention are shown in the drawings.

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

In the process of modern rail transportation, the train operation control system can supervise, control and adjust the train running speed and braking mode according to the objective conditions and actual conditions of the train operation, which plays a vital role in the safe operation of the train. For example, a common train operation control system may be a communication-based train control system (Communication Based Train Control System, CBTC).

The train operation control system usually includes the automatic train supervision (Automatic Train Supervision, ATS) subsystem of the dispatch center, multiple zone controllers (Zone Controller, ZC) and multiple computer interlocking zone subsystems ( computer interlocking, CI), wherein, a computer interlocking area subsystem corresponds to an interlocking area, and the interlocking area refers to the location area monitored by the computer interlocking area subsystem, the ATS subsystem, the CI subsystem and the ZC through wired or Wi-Fi.

Among them, the train automatic monitoring subsystem is usually set in a specific area of the whole line, which is also called the dispatcher workstation, which is used for the dispatcher to monitor the signal equipment and train operation information of the whole line or part of the train operation, and check the train operation. The automatic train monitoring subsystem mainly includes dispatcher workstation equipment, which is used to provide human-computer interaction interface for dispatchers, application server, which is used to receive station yard status data of station equipment and train on-board equipment. Location and status information; and a display device for displaying the station map, which is a simulated state diagram of the train running route and train operation. The station map is generated by the arrangement and combination of multiple station primitive objects. The station map The meta object is the graphical icon of the line, trackside equipment, stations along the line, trains and other station equipment in rail transit. The trackside equipment can be signals, turnouts, sections, screen doors, (active/passive) Transponder, etc. Among them, objects point to devices with the same properties or characteristics. For example, the station primitive includes equipment such as semaphore, semaphore 1 is an object of such equipment as semaphore, and semaphore 2 is an object of such equipment as semaphore.

The computer interlocking area subsystem mainly includes substation ATS equipment, interlocking upper computer and local workstation equipment. Each computer interlocking area subsystem corresponds to a local workstation. Among them, the substation ATS equipment is used to communicate with the dispatch center. Apply the server link to obtain the station yard status data, and display the status data on the local workstation equipment in the form of a station yard diagram, and interlock the upper computer to obtain and monitor the status of the trackside equipment corresponding to the interlock area. information.

The regional controller is used for real-time exchange of station status data with the train automatic operation system and train automatic protection system, CI subsystem and ATS subsystem carried on the train.

In the related art, during the actual operation of the train, the station map of at least one train route route area monitored by the train operation control system needs to be displayed on the display device. Usually, multiple areas can be set in the route route area. Each zone controller can exchange information with the computer interlock zone subsystems of multiple interlock zones monitored by the zone controller.

Among them, in the process of drawing the station yard map, for the train running lines including multi-area controllers and multi-interlocking, the existing graph element representation file is developed during the development process, and the station yard graph is stored for each station yard primitive object. The attribute information of the interlocking area and area controller to which the meta object belongs, and the amount of data stored is large. During the drawing process of the station yard, it is necessary to determine the station based on the attribute information of the interlocking area and the area controller corresponding to each station yard primitive object. The location information of the field primitive object in the generated site map requires a large amount of data to be parsed and stored, occupies storage space, and has low drawing efficiency for the site map.

Further, in the real-time refresh process of the station map, the substation ATS equipment in the local workstation obtains the status data of the station equipment from the application server. When the application server fails, it can only switch to the interlocking upper computer monitoring station. The status of the station equipment cannot be obtained, and the station diagram cannot be updated; and in the process of updating the station diagram, after the status data of the station equipment is obtained, it is usually necessary to compare the acquired status data with the stored data. The station and yard primitive object attributes, interlocking area attributes and regional controller attributes of each station yard primitive object are compared one-to-one, and the target station yard primitive object is determined to update the state, and the target station yard primitive object is determined to be updated. The status of the station and yard primitives is updated, and the updated station and yard map is displayed. However, the amount of data transmitted during this process is large, the system is stuck, and the query of the target station and yard primitive objects is time-consuming, which affects the real-time performance of updating the station and yard map.

Further, it is determined that the index of the target signal object in the station yard state data is A1 and the target state value of the target signal machine, according to the difference between the interlocking zone identification and the index of the interlocking zone stored when the initial station yard map is drawn. The corresponding relationship of The target signal array a of the interlocking area corresponding to the index 1 of the target interlocking area is determined in the plurality of signal arrays a and b. In the target signal array a, the index A1 of the target signal primitive is searched. The corresponding position identification is the target position identification, the state value of the target signal corresponding to the target position identification is updated to the target status value of the target signal corresponding to the index A1 of the target signal, and the updated site map is displayed.
