[0001] This invention relates to the field of railway marshalling yard technology, and in particular to a train assembly control method, device, equipment and medium for marshalling yards. Background Technology

[0002] A railway technical station includes a marshalling yard and a section station. It refers to a railway station with a dedicated shunting locomotive that can carry out marshalling, demarcation, and delivery operations. Its main function is to reassemble arriving trains into new trains.

[0003] Currently, all railway technical stations perform marshalling and demarcation operations according to the marshalling plan. In special circumstances where train routes need to be modified or trains are not running in accordance with the plan, the operation must be carried out according to the instructions of the railway bureau's dispatching department. However, this operating method lacks flexibility and cannot meet the needs of real-time changes in train flow, and the marshalling plan cannot keep up with the pace of railway network adjustments.

[0004] Therefore, a method is needed to quantitatively analyze operational and traffic conditions based on the current system and operational status, in order to improve the operational efficiency of technical stations. Summary of the Invention

[0029] Example 1

[0030] Figure 1 This is a flowchart of a train assembly control method in a marshalling yard according to Embodiment 1 of the present invention. This embodiment is applicable to situations where trains are re-assembled and de-assembled in a marshalling yard. This method can be executed by a train assembly control device in the marshalling yard, which can be implemented in hardware and / or software. This train assembly control device can be configured in a system with data acquisition capabilities. Figure 1 As shown, the method includes:

[0031] S110. Obtain marshalling description data and hump signal data corresponding to the target marshalling yard from at least one data system, wherein the marshalling description data includes shunting plan data and train plan data.

[0032] In this embodiment of the invention, the data sources for train marshalling include the existing train system and the integrated automation system. The existing train system refers to the system used in the marshalling yard, through which some basic data can be obtained, including: the direction of train flow at stations, the station name indicating the direction of train flow at each station, and the shunting tracks. Since the data in the existing train system is not updated in real time, the information lacks timeliness and accuracy. Therefore, some of the train marshalling description data is obtained from the integrated automation system. Among these, some of the train marshalling description data includes shunting plan data and train plan data, while the hump signal data comes from the hump automatic control system.

[0033] Optionally, the shunting plan data includes: the track for each coupler, the shunting method, and vehicle information; the train plan data includes: the confirmed report catalog, the number of cars in the formation, whether it is a through train, and the departure reporting time.

[0034] The real-time assembly process description information includes: the assembly start time for each arriving train for each departing train in each direction, the number of assemblies required for each arriving train to be matched with a departing train, and the identification information of each vehicle.

[0035] S120. Based on the marshalling description data and hump signal data, obtain real-time assembly process description information for each train in each direction of the target marshalling yard.

[0036] The process from the moment the first set of cars forming a train departing from a certain arrival station enters the marshalling yard to the moment the last set of cars forming that train enters the marshalling yard is called the train assembly process. The descriptive information for the train assembly process comes from the hump yard automatic control system. Hump signal data is obtained from the hump yard automatic control system via serial port. The hump signal data mainly refers to the reporting information of the shunting coupler and the car-dropping coupler, which indicates the time of shunting and car-dropping.

[0037] Furthermore, after obtaining real-time assembly process description information for each train in each direction of the target marshalling yard based on the marshalling description data and hump signal data, the process may further include:

[0038] Whenever a shunting plan update is detected, the shunting plan update is compared with the real-time assembly process description information to identify the identification information of the assemblies that need to be rearranged.

[0039] The identification information of the assembled vehicles that needs to be rearranged will be displayed to the user.

[0040] After the collected grouping description data is written into the database, if the shunting plan changes, the pre-stored written data will be used as the basis for analysis and compared with the updated shunting plan. If there is a conflict with the updated shunting plan, the written data will be regarded as an unreasonable plan. At this time, the assembly vehicles that need to change the dispatching plan will be marked according to the updated plan, and the original written plan will be displayed as an item and automatically prompted to the system user.

[0041] S130. Based on the real-time assembly process description information, a schematic diagram of the assembly process is drawn in real time, and the schematic diagram of the assembly process is visualized.

[0042] Since most railway technical stations are equipped with automatic hump yard control systems, they can accurately obtain the arrival time of trains in the arrival yard, marshalling yard, and departure yard. By combining the information obtained from the shunting plan and the marshalling plan, they can obtain the assembly process of each car and each marshalling direction, and visualize the assembly process of trains in each direction on the computer system.

[0043] Furthermore, in addition to visually demonstrating the assembly process diagram, it may also include:

[0044] If a first target train whose assembly time has exceeded a preset time threshold is identified in the assembly process diagram, a user prompt is given to the first target train.

[0045] If a second target train in an unbalanced assembly state is identified in the assembly process diagram, a user prompt is given to the second target train.

[0046] When calculating and analyzing the assembly process, if the first target train is identified as a vehicle whose assembly time is abnormal and exceeds the preset standard arrival time, the abnormal assembly time status of the first target train will be automatically alerted to the system user so that the marshalling yard personnel can respond in a timely manner.

[0047] Similarly, the second target train refers to the vehicles that are unevenly assembled during the assembly process. The reason for the uneven assembly may be that the station's scheduling level is insufficient or the arrival of trains is uneven, causing the second target train to stay in the marshalling yard for too long because it cannot meet the trigger conditions. At this time, the abnormal status will be automatically alarmed to the system user so that the marshalling yard personnel can adjust the scheduling plan in time.

[0048] This invention acquires marshalling description data and hump signal data corresponding to the target marshalling yard from at least one data system. The marshalling description data includes shunting plan data and train plan data. Based on the marshalling description data and hump signal data, real-time assembly process description information for each train in each direction of the target marshalling yard is obtained. Based on the real-time assembly process description information and hump signal data, a real-time assembly process diagram is drawn and visualized. This invention collects basic data from the existing vehicle system and integrated automation system, and obtains reporting data from the hump automatic control system via serial port. The collected data is used as the source for data analysis. Furthermore, the inventors creatively propose that by acquiring the assembly process information for each car and each direction, the train assembly process in each direction can be visualized on a computer system. This not only facilitates the daily management and scheduling of the marshalling yard but also improves the flexibility and operational efficiency of the marshalling yard.

[0049] Example 2

[0050] Figure 2 This is a flowchart of another train assembly control method in a marshalling yard provided in Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment, and correspondingly, as shown below. Figure 2 As shown, the method specifically includes:

[0051] S210. Call the first type of interface provided by the current vehicle system of the target formation yard to obtain the first type of formation description data corresponding to the target formation yard.

[0052] Specifically, the first type of train formation description data refers to the first data from the existing train system. The first data is data from stations that have not undergone comprehensive automation upgrades. By calling the first type of interface connected to the existing train system, some shunting plan data and train plan data mentioned in the above embodiments can be collected.

[0053] S220. Call the second type of interface provided by the integrated automation system to obtain the second type of marshalling description data corresponding to the target marshalling yard.

[0054] Specifically, the second type of train formation description data refers to the second data from the integrated automation system. The second data is data from stations that have undergone integrated automation upgrades. By calling the second type of interface connected to the integrated automation system, some of the shunting plan data and train plan data mentioned in the above embodiments can be collected.

[0055] S230. The first type of grouping description data and the second type of grouping description data are combined to obtain the grouping description data corresponding to the target grouping field.

[0056] The first type of grouping description data from the current vehicle system and the second type of description data from the integrated automation system are combined to obtain the grouping description data described in S110.

[0057] S240. Call the third type of data interface provided by the hump automatic control system to obtain the hump signal data corresponding to the target marshalling yard.

[0058] Specifically, the information on the shunting hooks included in the hump signal data refers to the time it takes for a vehicle to be unloaded from the original train using a shunting method; while the information on the vehicle being sent off the hump refers to the time it takes for the vehicle to slide freely down the slope due to the potential energy generated by the elevation difference from the top of the hump and enter the designated track below the hump.

[0059] S250. Construct a drawing coordinate system with system time as the horizontal axis and the number of vehicles as the vertical axis.

[0060] To better illustrate the assembly process with visual diagrams, refer to... Figure 3 The diagram illustrates the vehicle assembly process. The numbers 89345, 89347, and 89349 at the top of the diagram represent shunting train numbers, while the number 34121 at the bottom of the diagram represents the assembly train number.

[0061] S260. Whenever the current assembly start time of the currently arriving train used to construct the target departure train is identified from the real-time assembly process description information, the current annotation time point corresponding to the current assembly start time is marked in the drawing coordinate system.

[0062] like Figure 3 As shown, train 89345, as the first train in this assembly, began assembling its vehicles at 6:00 AM on January 1st. Therefore, 6:00 AM on January 1st is considered the start time of the current assembly, and the marked time points corresponding to the first assembly process are thus obtained in the graphical display interface.

[0063] S270. Detect whether there is an isolated marker time point in the drawing coordinate system corresponding to the target departing train. If so, obtain the historical number of vehicles of the historical arriving trains corresponding to the isolated marker time point.

[0064] Among them, isolated time points refer to the time points within the time interval of 6:00-9:00 where the number of vehicles gathering changes, from Figure 3 It can be seen that from 6:00 to 9:00, train 89345 assembled a total of 14 cars. These 14 cars formed the first assembly of trains. It can be seen that each group of cars formed a rectangular frame from the beginning to the end of the assembly. During the assembly process, the number of assembled cars continuously increased based on the number of assembled cars in the previous period.

[0065] S280. Based on the current annotation time point, the isolated annotation time point, and the number of historically gathered vehicles, draw the target rectangle in the drawing coordinate system using an overlay drawing method.

[0066] Figure 3 The first rectangle formed in the image represents the entire assembly process of train 89345. The horizontal coordinate of this rectangle is 6:00, which is the start time of the assembly, and 9:00, which is the end time of the assembly. The formation process of this rectangle includes isolated time points and the historical number of assembled vehicles. During the real-time update drawing process, the rectangle formed by the isolated time points and the historical number of assembled vehicles is continuously covered by the new update status, and finally a rectangle is obtained showing that 14 vehicles were assembled over a period of 3 hours.

[0067] S290. When it is determined that the currently arriving train is the last train used to construct the target departure train, the target line segment is drawn in the drawing coordinate system according to the current marked time point and the current number of vehicles assembled by the currently arriving train.

[0068] Similarly, train 89347, as the second train in this assembly, assembled 16 carriages at 9:00 AM on January 1st. Figure 3 The second rectangle in the diagram represents the result of the second assembly, at which point the number of vehicles has accumulated to 30. Train 89349, as the last train in this assembly, assembled 30 vehicles at 12:00 on January 1st, completing the assembly of 60 vehicles for train 34121. Therefore, 12:00 on January 1st marks the end of this assembly process, which is represented by a line segment.

[0069] S2100. Based on the real-time assembly process description information, a schematic diagram of the assembly process is drawn in real time, and the schematic diagram of the assembly process is visualized.

[0070] Optionally, based on the real-time assembly process description information, a schematic diagram of the assembly process is drawn in real time, which further includes:

[0071] In the assembly process diagram, each departing train and each arriving train are identified.

[0072] For each group of vehicles entering the marshalling yard, its arrival train number before marshalling and its departure train number after marshalling are recorded, i.e. Figure 3 In the diagram, 89345, 89347, and 89349 are the arrival train identifiers, while 34121 is the departure train identifier, thus ensuring that the entire assembly process is clearly and intuitively displayed.

[0073] The technical solution of this invention, through a refinement of the overall scheme, details a method for visualizing the dynamic assembly process of vehicles. By using the hump yard system to report train dismantling plans, the time when a target vehicle enters the marshalling yard track is obtained as the actual start time of its assembly. This process is repeated for each vehicle, acquiring the assembly times of all vehicles entering the marshalling yard track. Based on the order of their entry into the track, vehicles with the same assembly time are categorized, ultimately yielding the complete assembly process of the departing train, thus enabling the creation of an intuitive and visually appealing graphic.

The collected data serves as the source for data analysis.
