Description

Technical Field

[0001] The invention relates to the technical field of railway transportation information technology, in particular to an intelligent marshaling station-train automatic flow distribution and assembly system. Background Art

[0002] The train flow distribution and marshaling and disassembling plan is the traffic organization plan for the entire railway. In the actual production activities and technical operations of the station, the traditional train marshaling and disassembling plan is mainly manually compiled by the station dispatchers and assistant dispatchers. After manually pushing the flow calculation and meeting with the planner to meet the traffic flow that meets the driving conditions in the next stage, the shunting hook plan is manually compiled, and it can only be compiled one hook at a time and one train at a time. Since it is impossible to consider all traffic flows at one time, the track usage and shunting machine usage cannot be considered in place at one time, the station dispatchers often conduct repeated experiments to find the best solution within a limited time. Not only is the labor intensity high, but some train marshaling and disassembling still cannot achieve the expected effect, the track is not used reasonably, the shunting machine capacity is not maximized, causing station congestion and train departure delays. The traditional train disassembly and marshaling plan that completely relies on the manual push flow of station assistants is no longer suitable for the requirements of high-speed, high-density and high-load transportation organization under the new system and new layout.

[0003] The influencing factors of the automatic train distribution and disassembly system are diverse, and the correlations between the influencing factors are complex. It is a high-dimensional, nonlinear combinatorial optimization problem. Researchers at home and abroad have done a lot of research on the problem of "optimal planning for automatic marshaling and disassembly", but many studies consider relatively simple factors, simply aiming to improve the accuracy of train marshaling and disassembly, or simply aiming to improve the utilization rate of shunting machines. Some solutions are too idealistic, based only on theory, and have low practical application value. Some models and algorithms have a single test sample, and the samples fail to cover various situations in the actual production process, so it is difficult to apply them in practice. Therefore, it is necessary to provide an intelligent marshaling yard-train automatic distribution and disassembly system to solve the above technical problems. Summary of the invention

[0036] Example:

[0037] 1. The present invention deeply studies the station traffic organization process, actual production activities and technical operation process, deeply understands the business logic, conducts comprehensive data analysis and organization, determines a mathematical model of automatic train flow distribution, marshaling and disassembly that fits the actual situation, and provides an intelligent marshaling station-train automatic flow distribution and disassembly system.

[0038] 2. Construct the planning platform-marshaling yard from top to bottom in the marshaling solution operation mode. Figure 1As shown. The planning station issues shift plans and stage plans, provides feasible marshaling schemes, and provides overall line dispatch stage plans and shift plans. The marshaling station uses the planning station data as a basis, comprehensively considers its own station conditions, track idleness, shunting task status, freight loading and unloading plans and loading and unloading needs, and realizes fast, accurate and efficient vehicle flow organization and marshaling and disassembly plan preparation, obtains high track utilization rate, shunting utilization rate, reduces intermediate stops, and increases train turnover efficiency.

[0039] 3. Build a parameter maintenance information database. Create a parameter directory for the fixed business logic, business data, and judgment conditions required for the calculation process, and add them to the parameter maintenance information database. Digitalize station order information, no-slip and no-peak judgments, exchange flow judgments, and vehicle freight grouping judgments to provide expert data for automatic flow distribution and analysis, and promote the calculation and analysis process to obtain the optimal analysis results.

[0040] 4. The system uses iterative recursion, backtracking algorithm, and backpack algorithm to build a calculation model, and optimizes and infers the formation of an automatic train flow distribution marshaling and disassembly plan to maximize the train turnover efficiency, the number of departure cars, the number of high-quality trains, the track utilization rate, and the utilization rate of shunting locomotives, and ensure smooth traffic flow, reduce marshaling yard congestion, eliminate safety issues that may arise in the manual plan preparation process, and improve operation safety and plan quality. The automatic train flow distribution marshaling and disassembly system is based on the general principles of improving traffic flow organization efficiency, following station operation scheduling rules, and generating high-quality marshaling and disassembly plans. Specifically, improving traffic flow organization efficiency means that after automatic flow distribution marshaling and disassembly, as many departure plans as possible are fulfilled, and the departure car is delayed or the departure car cannot be prepared due to turnover failure. Improving the utilization rate of shunting locomotives means that the marshaling and disassembly plan can reasonably arrange the shunting locomotives, eliminating the situation where one shunting locomotive is working continuously while other shunting locomotives are idle, tasks are uneven, and shunting locomotives fail to work in parallel with high quality. Improving track utilization means that through high-quality traffic organization and marshaling and disassembling plans, the quality of traffic assembly can be improved, the number of chaotic tracks can be reduced, traffic transfer and unblocking can be quickly carried out, station congestion can be reduced, vehicle hook-overs during marshaling can be reduced, and the effect of opening new lines on empty tracks can be improved. Figure 2As shown. The overall calculation process is divided into the following multiple local algorithms: (1) Car marshaling sequence determination algorithm. (2) Actual field priority car marshaling algorithm. (3) Disassembly sequence determination algorithm. (4) Disassembly algorithm. (5) Flow distribution algorithm. (6) Disassembly sequence automatic adjustment algorithm. (7) Delay conflict adjustment algorithm. (8) Empty track new line opening algorithm. (9) Disordered line opening algorithm. And according to the strategy of manual plan compilation, each module is based on the following principles. Car marshaling sequence calculation principle: (1) Special marshaling plan corresponding to the departure car priority marshaling. (2) Train priority. Disassembly sequence determination principle: (1) Car flow that belongs to the station sequence and belongs to the direction far from the station sequence is disassembled first. (2) Arrival cars with fewer direction groups are disassembled first. Disassembly drop principle: (1) Drop according to the manually designated track. (2) Drop according to the departure car number.

(6) Flow is released according to the station sequence grouping rules. (7) Flow is released according to the freight grouping rules. (8) Flow is released according to the exchange flow set rules. (9) Flow is released according to the same direction attribute. Principle of automatic adjustment of the disassembly order: the arriving vehicles used by the departure vehicles with earlier departure points are disassembled first. Principle of flow distribution algorithm: the marshaling plan is divided into the plan issued by the planning station and the original marshaling plan corresponding to this train. These two marshaling plans are combined to form a combined marshaling plan, and then an empty car is added to form a combined empty car marshaling plan. The combined empty car marshaling plan is used to find the fully satisfied open track in the actual field track, and all situations are obtained by arranging and combining the track and the disassembly block, and then a reasonable plan is screened out. Finally, the marshaling plan issued by the planner is used to find the fully compliant one. Principle of opening a new line: (1) Short tracks are given priority for small operations. (2) Tracks with the least turnout influence are given priority for opening new lines. (3) Hooking is given priority.
