The present invention relates to the field of rail transit emergency response simulation, and in particular to a dynamic parameter calculation method based on a CTC simulation training procedure and an apparatus thereof.
At present, the standard response procedure template established for performing emergency scenario response training for train railway dispatching commanders is mainly static. Stations, equipment, signal status and vehicles that need to be processed are all fixed, and only specific fault procedures can be simulated, lacking universality and versatility.
In the dispatching command scenario, the stations are of different types. In addition, section screen, CTC operation information, equipment information, route information, fault information, train information adjusted in real time on the running chart and train status change at every moment. Therefore, the emergency response procedure should not only be able to relate to specific station equipment and car running information, but also be applicable to various stations and car running scenarios, and therefore can be used a plurality of times. In addition, it is necessary to ensure the independence and high scalability of the edited content in the response procedure, which are lacked in various simulation training projects.
Through retrieval, the Chinese Patent Application CN202011185003.9 discloses a simulation processing method of a CTC simulation system emergency response procedure representation. In this method, the CTC simulation system emergency response procedure representation is divided into a fixed part and a dynamic part, and the specific calculation and update processes of the dynamic part are provided. The fixed part can be used to represent standard operating procedures and terms, and the dynamic part can be used to represent variable information related to specific failure scenarios. This invention resolves the shortcomings of the static procedure, can adapt to the change of the fault position and the number of running trains, and provides the simulation of the emergency response procedure that is closer to the reality use scenario. However, the emergency response procedure established by this invention is not standardized enough, and the applicability is not strong enough. The calculating process of some of dynamic parameters is performed in a single-branch manner, which brings about the defects of parameter accuracy and real-time performance.
An objective of the present invention is to overcome the foregoing defects of the related art, and provide a dynamic parameter calculation method based on a CTC simulation training procedure with strong applicability, high real-time performance, and high accuracy.

In a preferred technical solution, the process parameter calculation node in step S255 is located in the parameterized multi-branch emergency response procedure template, and after the parameterized multi-branch emergency response procedure template flows to such step, calculation is triggered and the dynamic-parameter reserved word is replaced with a specific value.

In a preferred technical solution, the calculation terminal in step S25 maintains a calculation queue and a result mapping table, where intermediate results of branch calculations and a final result are all stored in the result mapping table, a specific value of a required parameter is read from the result mapping table when each branch calculation is started, and content in the result mapping table is updated after the branch calculations.
