Description

TECHNICAL FIELD

[0001] The present application relates to rail transit signal system, and particularly to a train timetable matching method and device based on shadow mode, equipment and medium. BACKGROUND

[0002] After the urban rail transit fault, the control center dispatcher will keep the local train operation normal by stopping the train and temporarily changing the route. The response of the fault section is to carry out related maintenance according to the pre-defined emergency plan, so as to complete the related fault repair as soon as possible. When the fault is repaired, the on-site gradually has the operation condition of the timetable before the fault, and the dispatcher needs to manually complete the on-site train adjustment to restore the normal timetable operation, and then enter the normal operation mode.

[0003] The existing fault recovery mode is that the dispatcher first switches the current operation mode back to the timetable operation mode, and then the system automatically matches the latest train number according to the train arrival information. Because the position of the train during the fault is not matched with the timetable, the real-time matched train number has a large error, and the dispatcher adjusts the train number according to the diagram in turn to complete the train number matching of the whole line until all the trains are normally restored to the timetable control state. This process takes a long time, and the frequently changing train timetable also greatly affects the arrival time of the train for the passengers on site. Such design is unscientific and cannot meet the needs of the industry development.

[0004] Through retrieval, Chinese patent publication CN112874586A discloses a kind of urban rail transit intelligent train timetable matching method, specifically discloses first according to the position relationship of all trains, the order of all trains is determined;Select the first train matching timetable journey in all train order, subsequent train is sequentially matched timetable journey according to planned timetable order, and matching weight is calculated.Then readjust train order, match timetable journey, calculate matching weight, until all train order is traversed.Finally, compare the sum of all train order matching timetable weight, select the train matching timetable scene with the maximum weight value.Sum of weight value.This existing patent is a kind of direct action on online system, through deviation cycle calculation weight, finally select a matching weight minimum, that is, the minimum error mode, directly form the matching relationship between train and timetable, this train matching timetable is universal for normal start operation, according to the order of departure timetable, but for operation process, how to restore to timetable mode after temporary adjustment timetable or fault recovery, it is still a difficulty in the industry, the main difficulty is that there is no matching between online train and timetable, how to choose a offline train scientifically or arrange an online train, there is great randomness, often rely on the daily work experience of dispatcher, there is no good calculation rule;Therefore, the dispatcher in the recovery process, according to experience, first try to restore a matching mode without the help of system, then manually arrange train and readjust train matching relationship according to operation condition, the result of this multiple adjustment can only be temporarily applied to train, which will make passengers feel that the running time of train is changing all the time;At the same time, this matching relationship also lacks scientific basis, but the dispatcher also has no suitable environment to simulate in advance.

[0005] Therefore, how to solve the online train automatic matching of current site temporary replacement timetable and site operation fault recovery becomes a technical problem to be solved. SUMMARY

[0089] Comprise the following steps:

[0090] Step 201, the automatic matching deduction mode of the turnaround point first determines whether the currently loaded plan diagram belongs to single route operation, and the timetable management module will feedback whether the current timetable belongs to single route operation or multi-route operation; because the automatic matching deduction mode of the turnaround point is most suitable for single route, therefore the algorithm will be verified and reminded in advance.

[0091] Step 202, the automatic matching deduction mode of the turnaround point, if it is confirmed to be a single route, the current automatic matching algorithm will find out the turnaround point of the single route timetable, and then according to the train near the current position of the turnaround point, take the first train entering the turnaround track as the first starting point, match the previous train of the current turnaround point train in the timetable, and match the corresponding train number relationship of the train.

[0097] Step 208, the train position optimal matching mode keeps the artificial car state for the train that cannot be matched, and pops up a list of matching prompts for the planned train that is missing. Finally, the matching of all trains on the line is completed.

[0098] Step 209, the same destination automatic matching mode is mainly suitable for the mode of multi-route operation, and the system defaults the turnaround point of each route train to be punctual operation, and then filters out all the turnaround rails that have not been turned at the current time point by means of the timetable management module.

[0099] Step 210, the same destination automatic matching mode then corresponds to the first actual train entering the turnaround rail, and completes the response matching;

[0100] Step 211, the same destination automatic matching mode completes the one-to-one matching of the planned train and the actual train between the turnaround rails in turn after completing the matching of all the turnaround rail trains;

[0101] Step 212, the same destination automatic matching mode keeps the artificial car state for the train that cannot be matched after completing the matching of all the turnaround interval trains, and pops up a list of matching prompts for the planned train that is missing.
