The present invention relates to the technical field of railway turnout equipment, provides a railway turnout curved sharp rail anti-wear device, comprises a sleeper arranged in parallel, a basic rail laid on the sleeper and a curved sharp rail bolted to the basic track turnout, the basic rail located on the left side of the locomotive running direction comprises a left transition section, an overheight section and a right transition section, and the height of the left transition section to the super-high section gradually increases, and the height of the super-high section to the right transition section gradually decreases. The application discloses by arranging the super-high section on the railway in front of the turnout, so that the height difference between the basic rails on both sides is generated, when the locomotive passes through the curved sharp rail, the car body can automatically tilt laterally at a certain angle, the centrifugal force required for the steering is balanced by the horizontal component of the gravity of the locomotive, the abnormal impact of the locomotive on the curved sharp rail, the maintenance workload of the curved sharp rail is reduced, the service life of the curved sharp rail is prolonged, and the superelevation quantity of the ultra-high section can be uniformly reduced to zero along the longitudinal direction by arranging the left transition section and the right transition section respectively at both ends of the ultra-high section, thereby improving safety。

The present invention discloses a multi-scale damage evolution analysis method for ballastless track, including obtaining target ballastless track data information, generating a random aggregate model, establishing an initial model as the current model and setting the current constraints, applying the load of the current loading step to the current model under the current constraint conditions and solving, calculating the damage index of the beam element and the first-order planar element, deleting all constraints and loads of the current model, converting the beam element into the first-order planar element, refining the first-level planar element to obtain the fine element, traversing the refinement element and importing the random aggregate model, adding the contact relationship again to obtain a new current model and setting the new current constraintRepeat the above steps until the loading step meets the set requirements, and perform post-processing to complete the multi-scale damage evolution analysis of the target ballastless track. The invention also discloses a system for realizing the multi-scale damage evolution analysis method of the ballastless track. The present invention has high reliability, good accuracy and high efficiency.

The invention belongs to the technical field of training system, and discloses a prefabricated subway station construction training system, including prefabricated subway frame structure, The prefabricated subway moving component, the prefabricated subway moving component moves horizontally through the horizontal moving low column, the top of the prefabricated subway moving component is symmetrically provided with a mounting seat moving piece, and further comprises: the prefabricated mounting structure is movably connected to the top of the prefabricated subway moving component; the present invention is a track model of a means of transportation, can also be called a prefabricated subway station training model, the present invention has improved the prefabricated subway frame structure, so that the prefabricated arc roof can reduce the center of gravity through the prefabricated center of gravity plate, so that the prefabricated subway frame structure is very firm after being connected, and the whole installation operation is saferThe improved prefabricated subway frame structure can still be used for semi-automatic installation operations with prefabricated subway moving components, prefabricated installation structures, and semi-automatic disassembly limited components.

The invention discloses an obstacle perception method and device based on subway car-ground wireless communication, which belongs to the field of rail transit, and the method comprises: under the condition of establishing a communication connection with the oncoming on-board equipment, the perception state of the neighbor base station is closed and going, and a disconnection message is sent to the neighbor base station in the case of the existence of the neighbor base station, and in the case of the existence of the neighbor base station, a recovery message is sent to the neighbor base station all the way; under the condition of receiving the recovery message sent to the neighbor base station, the perception state of each direction is turned on, and under the condition that the neighbor base station in either direction is turned on the opposite sensing state, a perception connection is established with the neighbor base station of the corresponding direction。 This method can realize the reuse of communication services and perception services without increasing the number of base stations, reduce the construction cost and maintenance cost caused by the need for perception services, and can effectively avoid the misjudgment of obstacles caused by trains, so as to achieve accurate obstacle perception judgment.

The invention discloses a train control data acquisition method, device, electronic equipment and storage medium, relates to the technical field of rail transit. The method of obtaining the data of the column control comprises: obtaining the preset initial keywords and data source, splitting the matching keywords into sub-matching keywords of at least two hierarchies according to the preset target identification rules, matching the sub-matching keywords of each hierarchy in turn in the data source to determine the initial column control data corresponding to the target field, and adjusting the initial column control data according to the preset data format to generate the target column control data. The embodiment of the present invention realizes that the matching keywords are automatically split according to the hierarchical structure, the sub-matching keywords of each hierarchical structure are matched within the range of the successful matching keywords of the previous hierarchical structure, the matching efficiency is improved, and the initial column control data of matching is automatically adjusted to the target column control data of the preset data format, and the efficiency of obtaining the target column control data is improved.
