Detailed Description
Reference will now be made in detail to the present embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The train operation time optimization method, system, storage medium, and electronic device of the present embodiment are described below with reference to the drawings.
Fig. 1 is a flowchart of a train operation time optimization method according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S1: and determining the train needing to be subjected to emergency scheduling at the train running time in the emergency state.
The method for determining the train needing to be emergently scheduled at the train running time in the emergency state comprises the following steps: paving speed limit symbols in an emergency state, wherein the speed limit symbols comprise speed limit speed, starting mileage and ending mileage of a speed limit section; and determining the train needing to be subjected to emergency scheduling at the train running time according to the speed limit symbol.
Specifically, when the train runs in an emergency such as severe weather, the speed limit symbol can be paved, so that the affected train needing emergency dispatching at the train running time can be selected according to the information such as the starting mileage, the ending mileage and the like in the speed limit symbol, and the interval speed limit is carried out. For example, all trains before the mileage is over need to be dispatched urgently.
Step S2: and setting a speed limiting section in a driving section from the departure station to the arrival station of the train, and limiting the speed of the train in the speed limiting section.
For example, the train has a departure station A and an arrival station B. When the train runs from A to B, in case of emergency such as severe weather, the train in the section can be automatically slowed down by setting the speed-limiting section. Because the running time (for example, the running time from A to B is a preset hour, and the arrival time is a preset time) is influenced, the running time of the train can be adjusted by calculating the running time of the speed-limiting section and other running sections (for example, a departure station to a speed-limiting section).
It should be noted that, in this embodiment, a plurality of speed-limiting sections may be set in a section from the departure station to the arrival station, so as to implement automatic slow movement of the train in the section through the plurality of speed-limiting sections, and adjust the operation time of the train by calculating the operation time of each speed-limiting section and the operation time of other traveling sections.
In one embodiment of the invention, the speed-limiting section is set through the speed-limiting symbol, and the speed-limiting symbol is mapped to a kilometer post system for train running so as to obtain the distance from the departure station to the starting point of the speed-limiting section, the distance from the speed-limiting section and the distance from the ending point of the speed-limiting section to the arrival station.
Specifically, the speed limit symbol includes a starting mileage and an ending mileage, so that after the speed limit symbol is mapped to a train driving kilometer scale system, the distance from the departure station to the starting mileage can be determined according to the starting mileage, the distance from the ending mileage to the arrival station can be determined according to the ending mileage, and the distance of the speed limit section can be determined according to the starting mileage and the ending mileage.
In this embodiment, the speed-limit interval of the speed-limit section can be determined according to the speed-limit symbol. For example, the distance of the speed-limiting section is equal to the distance from the departure station to the arrival station, and the whole speed limit of the section can be judged; the distance of the speed-limiting section is smaller than the distance from the departure station to the arrival station, and the section part speed limit can be judged. Therefore, the calculation module can be called according to the speed limit interval to carry out corresponding calculation to obtain corresponding operation time, and the operation time is adjusted.
In one embodiment of the invention, the method further comprises recording the train mileage per second during the train running process, and slowing down the train when the train mileage reaches the preset mileage so that the speed of the train reaching the speed-limiting section is equal to the speed-limiting speed.
Specifically, the speed limit symbol includes the speed limit speed as described above, and the speed limit speed is the maximum operation speed at which the train is limited to travel in the speed limit section. Therefore, in order to leave allowance for the train entering the speed-limiting section, the speed reduction time or the driving mileage can be preset. For example, the driving mileage is preset, then the train mileage per second in the driving process of the train is recorded by defining a data structure for recording the mileage, and when the train mileage reaches the preset mileage, namely the preset driving mileage, the speed of the train is reduced, so that the speed of the train reaching the speed-limiting section is equal to the speed-limiting speed.
Step S3: and respectively determining the running time of the train from the starting station to the starting point of the speed-limiting section, the speed-limiting section and the ending point of the speed-limiting section to the arrival station.
Before determining the runtime, the method further comprises: the method comprises the steps of obtaining a train type of a train, and locally reading a configuration file in a dispatching centralized system according to the train type of the train so as to obtain the acceleration of the train in a uniform acceleration stage and the acceleration of the train in a uniform deceleration stage.
Specifically, the local configuration file of the dispatching centralized system can be read according to the type of the motor train unit to which the train belongs so as to obtain the natural attributes of the train, wherein the natural attributes comprise the acceleration of the train in a uniform acceleration stage and the acceleration of the train in a uniform deceleration stage. Of course, the ceiling speed of the train, that is, the maximum speed of the train running outside the speed-limited zone, can also be obtained.
Further, the step of respectively determining the running time of the train from the departure station to the starting point of the speed-limiting section, the speed-limiting section and the ending point of the speed-limiting section to the arrival station comprises the following steps: acquiring the initial speed of a train, the speed of the train running to the starting point of a speed-limiting section and the speed of the train running away from the ending point of the speed-limiting section; and respectively determining the running time of the train from the departure station to the starting point of the speed-limiting section, the speed of the train to the ending point of the speed-limiting section and the train to the arrival station according to the initial speed, the speed of the train to the starting point of the speed-limiting section, the speed of the train to the ending point of the speed-limiting section, the acceleration of the uniform acceleration stage, the acceleration of the uniform deceleration stage, the distance from the departure station to the starting point of the speed-limiting section, the distance from the speed-limiting section and the distance from the ending point of the speed-limiting section to the arrival station.
In this embodiment, the speed of traveling to the starting point of the speed-limited section and the speed of traveling away from the ending point of the speed-limited section can be determined according to the train-to-on attribute. After the parameters such as the speed, the acceleration and the like are acquired, the train passing opening attribute of the front and rear stations can be analyzed, and if the train after the speed limit section is arranged cannot pass through the front and rear stations at the original passing speed, the slow movement caused by the speed limit section influences the running time of the front and rear trains (the running time is not necessarily influenced by the speed limit section because the train runs at the ceiling speed outside the speed limit section). Therefore, the running time of the train on the train line can be adjusted through the running time of each section calculated by the train dispatching and traction algorithm.
Step S4: and allocating the operation time to the train operation line so as to adjust the operation time of the train on the train operation line.
Specifically, the train running time of the front and rear sections of the current driving section and the arrival and departure point of the current arrival station can be adjusted by the running line adjusting module in the high-speed rail dispatching centralized system.
In this embodiment, the running time of the train on the train running line is adjusted according to the running time obtained by the calculation, so that reasonable plan adjustment under an emergency condition can be ensured, and the efficiency of emergency handling during traveling is improved.
