Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
As shown in fig. 1, a method for managing the ordering of rail transit line resources includes the following steps:
s101, analyzing a track side line loop deadlock scene, and establishing a deadlock static prevention strategy;
step S102, reasonably making an operation plan for avoiding resource deadlock loop waiting;
step S103, applying for all needed resources for each train at a time;
step S104, a running task sequence verification mechanism is formulated;
step S105, supervising and executing the running task.
The invention provides a train operation control system resource management strategy based on autonomous control through static and dynamic analysis of line resources, reduces the space time of the line resources through reasonable resource division and dynamic scheduling strategy, improves the utilization rate of the line resources, and simultaneously avoids the problems of operation deadlock and mismatching of actual operation tasks of the train and an operation plan.
The method comprises the following specific processes:
1. and analyzing a track side line loop deadlock scene, and establishing deadlock static prevention. According to the topological relation of the station yard, a circulation chain possibly formed by train running paths is analyzed, four types of loop deadlock running paths are shown in fig. 2, resources obtained by each train running task in the chain are simultaneously requested by the next train running task, and a loop deadlock scene is determined according to the track traffic station yard topological logic and the exclusive characteristics of the resources.
2. An operation plan is reasonably formulated to avoid resource deadlock loop waiting. When an operation plan is formulated, a reasonable train operation task sequence is established based on the current station type, the task sequence in a loop deadlock scene is avoided, and a unique operation task sequence number is given.
3. After a reasonable operation plan is formulated, all needed resources are applied for each train at a time. Because the track traffic signal system adopts dynamic application and resource allocation, the resources required by all current running tasks are applied for once according to the sequence of operation planning and arrangement before the resources are allocated, and the resources are orderly sent to a train and a resource manager and checked based on an ordered list, and the deadlock prevention mode adopts 'whole-section application, independent allocation', namely: after a section of train operation task is applied, any section of area in the operation task is immediately allocated to the train under the condition that the related interlocking check condition is met, and the allocation condition of the comprehensive line resources of the train and the position of the preceding train are completed for tracking operation.
4. A task order verification mechanism is run. All requests for train operation tasks are strictly in ascending order, and the next operation task can be applied after the previous request is satisfied. After the running dispatching command system issues an running task for the train, the resource manager needs to feed back the serial number of the running task and the task receiving state to the running dispatching command system when receiving the running task application, and before the resource manager does not give feedback, the running dispatching command system cannot issue the running task for the subsequent train. And verifying the sequence of the running tasks sent by the resource manager and the running dispatching command system according to the sequence number allocated to the running tasks by the running plan. Once the serial numbers of the running tasks are arranged, deadlocks generated by reasonably merging the running tasks through the issuing sequence of the tasks cannot be changed at will, and meanwhile, the running plans can be strictly matched, so that the train running order is prevented from being disordered.
5. The running tasks are supervised and executed. The resource manager reasonably sorts and manages the received tasks for each train applying the rail transit line resources; and finally, each train is operated safely and orderly according to the acquired line resources and the established mobile authorization, is sequenced according to the first-to-first-obtained principle, and sequentially allocates the line resources needing to be exclusive for the subsequent trains according to the process of the operation tasks executed by the trains and the process of releasing the resources, so that the operation of each train is ensured to be strictly matched with the requirements of the operation plan of the driving dispatching command system.
