Description

Method and device for automatically adjusting train running status based on station equipment status

Technical Field

The present application relates to a method for automatically adjusting the running status of a train based on the status of station equipment.

Background technique

As an important part of the decentralized autonomous centralized dispatching system (FZK Centralized Traffic Control System, FZK CTC), the train operation diagram provides a basis for train dispatchers to command train operations by adjusting and issuing train operation plans, thereby ensuring the safe, stable and efficient operation of trains.

When a station equipment in a railway fails, it will affect the operation of trains related to the control of the equipment. Furthermore, it may endanger the safety of nearby trains. Therefore, it is necessary to adjust the train operation plan in a timely manner. At present, the communication of the fault status of the station equipment depends on the station dispatcher, and the adjustment of the train operation plan is mainly completed by manual operation. This situation reduces the efficiency of emergency adjustments of trains, and makes the plan adjustment easily affected by factors such as the experience and psychological state of relevant staff. Therefore, realizing the automatic adjustment of the train operation plan according to the status of the station equipment will ensure the efficiency of emergency adjustment of the train operation plan in the event of a station equipment failure, and at the same time improve the reliability of the adjustment of the train operation plan, which is particularly important when the station equipment fails.

Summary of the invention

In order to solve the problem in the prior art that when station equipment fails, the train operation plan needs to be adjusted manually, resulting in low adjustment efficiency and easy errors, the present invention provides a method and device for automatically adjusting the train operation status based on the station equipment status, which can automatically adjust the train operation plan according to the operating conditions of the station equipment, thereby improving the adjustment efficiency of the train operation plan and the reliability of the adjustment plan.

To achieve the above objectives, the present invention provides a method and device for automatically adjusting the train running status based on the status of station equipment.

A method for automatically adjusting a train running state based on a station equipment state, the method comprising:

S10, the information acquisition module acquires the status information of the station equipment;

S20, a parameter generation module generates a restriction parameter according to the status information of the station equipment;

S30, the automatic adjustment module obtains the restriction parameter;

S40, the automatic adjustment module adjusts the train operation plan according to the restriction parameters;

S50, the timing module counts the time interval T, and after the time interval T, executes S10-S40 again.

In this scheme, the status information of the station equipment is obtained by setting the information acquisition module, the parameter generation module generates the restriction parameters according to the station equipment information obtained by the information acquisition module, and the automatic adjustment module judges the equipment status of the station according to the restriction parameters, and compares the train that will enter the station according to the original train operation plan with the current station equipment status to adjust the subsequent train driving plan. If the entry conditions are not met, the train is controlled to stop at the previous station or stop within the section, or the train's entry track is adjusted. The automatic adjustment module automatically adjusts the subsequent train operation plan by comparing the station equipment information and the existing train operation plan, avoiding the problem of easy errors and low efficiency in manually obtaining station equipment data and adjusting the train operation plan, improving the adjustment efficiency of the train operation plan, reducing the probability of errors during the adjustment process, and ensuring the safety of station operation.

Preferably, the status information of the station equipment includes whether the station equipment is in a normal state or an abnormal state.

In this solution, the judgment module determines whether the station equipment is in normal operation, and reminds the station staff of the working status of the station equipment. If the station equipment is in an abnormal state, the station staff is reminded to deal with it in time.

Preferably, the station equipment for acquiring status information includes: switches, signal machines, sections and tracks, power arms and active transponders.

In this solution, status information is generated through the working status and location information of various equipment in the station, and then restriction parameters are generated based on the status information.

Preferably, when the station equipment is in an abnormal state, the parameter generation module generates restriction parameters according to the state information of the station equipment; the restriction parameters include whether each track, entrance and exit, and switch in the station is out of service and the estimated outage time.

In this solution, the status information of each device in the station is summarized to obtain the outage status of the track, entrances and exits, and switches, which simplifies the subsequent judgment process and improves the efficiency of subsequent adjustments to the train operation plan.

Preferably, the automatic adjustment module adjusts the train operation plan according to the restriction parameter, including:

S41, the judgment module judges whether it is an individual track restriction or a station overall restriction according to the restriction parameter;

If it is a restriction on individual stock channels;

S42, the automatic adjustment module adjusts the track where the train stops according to the available tracks;

If it is a station yard overall restriction, the judgment module judges the position of the train that will enter the station in the original train schedule;

S43, for the first type of train that has not entered the adjacent section of the station where the fault occurs, the automatic adjustment module adjusts the judgment module to judge that the first type of train in the original train schedule temporarily stops at the previous station;

S44, obtaining the maximum braking acceleration and braking distance of the second type of train that has entered the adjacent section of the station where the fault occurs, and the automatic adjustment module adjusts the second type of train to stop in the section.

In this scheme, by dividing the faults into individual track restrictions and overall station restrictions, when the fault is an individual track restriction, some trains can still enter the station, and when the fault is an overall station restriction, trains are not allowed to enter the station. The station equipment faults are handled in a graded manner to avoid prohibiting all trains from entering the station when only individual track restrictions occur, thereby improving the utilization efficiency of the station.

Preferably, the automatic adjustment module adjusts the train operation plan according to the restriction parameter and further comprises:

S45. The automatic adjustment module limits the speed of all trains in the station where the failure occurs.

In this solution, by limiting the speed of all trains in the station where the fault occurs, even if the train encounters an emergency during operation, relevant personnel have more time to respond, thereby improving the safety of train operation in the station where the fault occurs.

Preferably, the judging module judges whether it is an individual track restriction or a station overall restriction according to the restriction parameter, including:

S411, judging whether the number of remaining tracks allowed for trains to enter during the estimated downtime meets the number of trains that are about to enter the station according to the locations of the problematic tracks, the entrances and exits, and the switches contained in the restriction parameters;

If the number of remaining tracks is greater than or equal to the number of trains entering the station, it is determined to be a restriction on individual tracks;

If the number of remaining tracks is less than the number of trains entering the station, it is judged as an overall station restriction.

In this solution, by introducing a station fault classification judgment method, the number of remaining available tracks is used to determine whether it is an individual track limitation or an overall station limitation, so that the judgment module can judge the fault level by itself, and the automatic adjustment module makes corresponding adjustments based on the judgment result of the judgment module. There is no need for manual judgment whether it is an individual track limitation or an overall station limitation, which improves the judgment efficiency and avoids the occurrence of manual judgment errors.

Preferably, the number of remaining tracks is obtained by calculating the difference between the total number of tracks in the station and all the inactive tracks in the station. Preferably, the determination module determines the position of the train that will enter the station in the original train schedule, including:

S431, the information acquisition module acquires the mileage information of the train that will enter the station;

S432, the judgment module judges the position of the train that is about to enter the station according to the mileage information of the train that is about to enter the station and the position information of each station on the line.

In this solution, the information acquisition module obtains the mileage information of the train. Since the train's route is fixed, the current position of the train on the track can be calculated accordingly after the mileage information is obtained. The mileage information is only one-dimensional information with less data content. When used for railway train positioning, the mileage information can accurately determine the current position of the train. By recording the mileage information of the train to determine the current position of the train, the complexity of obtaining the train's position information is reduced while improving the train's positioning accuracy.

Preferably, the information acquisition module acquires the mileage information of the train that is about to enter the station, including:

S4311. The mileage information of the train that is about to enter the station is recorded in a dynamic array and transmitted to the information acquisition module.

In this solution, the mileage information of the train is recorded in a dynamic array, and the occupied storage space is dynamically adjusted according to the mileage of the train, thereby improving the efficiency of storage space utilization.

Preferably, the judgment module judges that the maximum braking acceleration of the second type of train that has entered the adjacent section of the station where the fault occurs includes:

S441, the automatic adjustment module reads a configuration file stored locally;

S442. The judgment module reads the maximum braking acceleration of the second type of train from the configuration file.

Preferably, obtaining the maximum braking acceleration and braking distance of the second type of train that has entered the adjacent section of the station where the fault occurs includes:

S443, the automatic adjustment module reads a configuration file stored locally;

S444, obtaining corresponding ceiling speed, uniform acceleration and uniform deceleration acceleration from the configuration file according to the train model;

S445. Calculate the braking distance of the train according to the ceiling speed, the uniform acceleration and the uniform deceleration acceleration.

In this solution, the relevant parameters of the train are directly read in the local configuration file according to the train model, so as to avoid the failure of data transmission due to network failure, improve the reliability of data acquisition, and estimate the parking position of the second type of train according to the obtained braking distance.

Preferably, after the automatic adjustment module adjusts the train operation plan according to the restriction parameters, it further includes:

S51, determining whether the train operation plan before and after the adjustment has changed;

S52, if the train operation plan before and after the adjustment is the same, then the train operation plan in the train control software is not updated;

S53. If the train operation plans before and after the adjustment are different, the train operation plan in the train control software is updated to the adjusted train operation plan.

In this scheme, by comparing whether the train operation plans before and after adjustment are the same, if the fault occurs on an unused track, the train operation plan before and after the adjustment may not change. When the train operation plan does not change, the train operation plan will not be updated to avoid errors in the train operation plan caused by errors in the transmission process, thereby reducing the probability of errors in the train operation plan.

Preferably, the estimated outage time is initially set to 10 minutes, and the estimated outage time is subsequently corrected by successively acquiring the status of the station equipment.

In this scheme, the estimated outage time is initially set to 10 minutes, which is the time required for general station equipment repairs. The outage time is sent to subsequent trains and adjacent stations and then updated based on the maintenance status of the equipment. The commonly used maintenance time is taken as the initial estimated outage time, which makes it easier for trains and stations along the line to plan their driving plans accordingly.

Preferably, the timing module measures the time interval T according to the time when the station equipment is in the normal state or the abnormal state;

When the station equipment is in a normal state, the time interval T is set to T1.

When the station equipment is in an abnormal state, the time interval T is set to T2.

and said T1 is greater than T2,

In this solution, T1 and T2 are set to correspond to the detection time intervals when the station equipment is in a normal state and when the station equipment is in an abnormal state, respectively. When the station equipment fails, the detection time interval is shortened, the detection frequency is increased, and the station equipment information is updated in time; when the station equipment works normally, the station equipment information is detected once at a larger time interval to ensure timely monitoring of the station equipment without generating too much equipment information data, resulting in excessive occupation of storage space.

Preferably, the T1 is set to 1 minute, and the T2 is set to 20 seconds.

In this solution, when a problem occurs with the station equipment, the station equipment status information is collected every 20 seconds, so that after the station equipment is repaired, the information that the equipment has returned to normal can be collected in time and the driving route can be replanned; when the equipment is in normal working condition, the station equipment information is collected once a minute. Compared with the working status of the station equipment, collecting the information once a minute can ensure the frequency of collecting the station equipment status information and ensure timely monitoring of the station equipment without generating too much equipment information data, resulting in excessive occupation of storage space.

The present application also provides a train running state automatic adjustment device based on the station equipment state, the automatic adjustment device is used to implement the above-mentioned train running state automatic adjustment method based on the station equipment state, the automatic adjustment device includes:

An information acquisition module, which is used to acquire equipment information in the station;

An automatic adjustment module, the automatic adjustment module is used to adjust the train operation plan according to the restriction parameters;

A timing module, wherein the timing module is used to time a time interval.

In this scheme, the status information of the station equipment is obtained by setting the information acquisition module, the parameter generation module generates the restriction parameters according to the station equipment information obtained by the information acquisition module, and the automatic adjustment module determines the equipment status of the station according to the restriction parameters, and adjusts the subsequent train operation plan according to the train that will enter the station in the original train operation plan and the current station equipment status. If the station entry conditions are not met, the train is controlled to stop at the previous station or stop within the section, or the train's entry track is adjusted. The automatic adjustment module automatically adjusts the subsequent train operation plan by comparing the station equipment information and the existing train operation plan, avoiding the problem of easy errors and low efficiency in manually obtaining station equipment data and adjusting the train operation plan, improving the adjustment efficiency of the train operation plan, reducing the probability of errors during the adjustment process, and ensuring the safety of station operation.

As shown in FIG1 , this embodiment provides a method for automatically adjusting the running status of a train based on the status of station equipment, comprising the following steps:

S10, the information acquisition module acquires the status information of the station equipment. The information acquisition module is electrically connected to each device in the station and acquires the status information of the station equipment at a certain time interval. In this embodiment, the station equipment includes: switches, signal machines, sections and tracks, power arms, and active transponders. The status information of the station equipment includes whether the station equipment is in a normal state or in an abnormal state. When the station equipment is in an abnormal state, the track cannot be used. The status information includes the number of remaining tracks and the estimated downtime. The equipment conditions that may cause the station equipment to be in an abnormal state are as follows:

A turnout is a line connection device that allows locomotives and vehicles to transfer from one track to another. The problems that may exist in a turnout include but are not limited to the following:

Lost indication, the specific status of the switch cannot be obtained; single closure, the switch is blocked alone; squeezed switch, the point rail and the main rail are squeezed apart; four-open, the point rail and the main rail are not tightly attached; there is no electricity for switch positioning; there is no electricity for switch reverse position; the branching is poor and the vacancy has not been confirmed.

The signal light filament is blown.

Possible problems with intervals and tracks include but are not limited to the following:

Red light band, the track section causes the station map to show the section as red; the track has no electricity; the track is blocked; the branch is poor and has not been confirmed to be idle.

The power arm has no power.

Active transponder fault.

In other embodiments, the station equipment failure also includes failures such as switch idling.

After the information acquisition module obtains the status signal of the station equipment, S20, the parameter generation module generates the restriction parameters according to the status information of the station equipment. The restriction parameters are used to describe the available status of the station. For example, when a track fails and cannot be used, the information acquisition module obtains the status information of the track that fails. The parameter generation module generates the restriction parameters according to the status information obtained by the information acquisition module. The restriction parameters include whether each track, entrance and exit, and turnout in the station are disabled and the estimated deactivation time if disabled. By collecting the status information of the turnout, signal, section and track, power arm and active transponder and other equipment, it is processed into the restriction parameters of the track, entrance and exit, and turnout. For example, if the signal fails, it means that the entrance and exit corresponding to the signal cannot be used. If the power arm fails, it means that the track where the power arm is located cannot be used. If the active transponder fails, it also means that the track where the active transponder is located cannot be used. Therefore, the restriction parameters of the track, entrance and exit and turnout can be generated according to the collected station equipment information. For example, if the track fails, the restriction parameters such as the estimated deactivation of 10 minutes are sent to the automatic adjustment module.

S30, the automatic adjustment module obtains the restriction parameter, that is, the parameter generation module transmits the generated restriction parameter to the automatic adjustment module;

S40. The automatic adjustment module adjusts the train operation plan according to the restriction parameters. After obtaining the restriction parameters of the station equipment, the automatic adjustment module compares the impact caused by the station equipment failure (for example, the track that needs to be deactivated in the next period of time) with the existing train operation plan. If a conflict occurs, for example, the original train operation plan needs to use the track that is deactivated due to the failure, the automatic adjustment module adjusts the train operation plan to avoid the train entering the deactivated track.

As shown in FIG. 2 , S40, the automatic adjustment module adjusts the train operation plan according to the restriction parameters, including:

S41. The judgment module determines whether it is an individual track restriction or an overall station restriction based on the restriction parameters.

If the judgment result is that individual tracks are restricted; S42, the automatic adjustment module adjusts the track where the train enters the station and stops according to the available tracks. At this time, even if some equipment in the station fails, the remaining available tracks can still support the trains that are about to enter the station. The only problem involved is that a track that needs to be occupied by the original train operation plan currently has equipment failure and cannot be used. In this case, the train operation plan is adjusted and the track occupied by the train entering the station is modified.

If the judgment result is that the station is restricted as a whole; S43, the judgment module judges the position of the train that will enter the station in the original train schedule. For the first-class train that has not entered the adjacent section of the station where the fault occurs, the automatic adjustment module adjusts the first-class train to temporarily stop at the previous station. When an overall station failure occurs, the corresponding vehicle is not allowed to enter the station where the overall station restriction occurs. In this case, the train that is about to arrive should be allowed to stop at the previous station as much as possible. Therefore, for the first-class train that has not entered the adjacent section of the station where the fault occurs, the automatic adjustment module adjusts the train operation plan and orders it to stop at the previous station, waiting for the station equipment to be repaired or the station to have the ability to receive trains before leaving the previous station.

If the judgment result is the overall restriction of the station; S44, the judgment module judges the position of the train that will enter the station in the original train schedule, obtains the maximum braking acceleration and braking distance of the second type of train that has entered the adjacent section of the station where the fault occurs, and the automatic adjustment module adjusts the interval parking of the second type of train. For the train that has left the previous station and has equipment failure in the station when traveling in the adjacent section, first determine its maximum braking acceleration, order the second type of train to stop in the interval, and wait for the station equipment to be repaired before entering the station. And calculate the expected parking position of the second type of train according to the braking distance. In this embodiment, if the judgment result is the overall restriction of the station, the automatic adjustment module adjusts the train operation plan according to the restriction parameters and also includes: S45, the automatic adjustment module processes the speed limit of all trains in the station where the fault occurs. In the station where the fault occurs, even the train running normally on the track is also subject to speed limit processing, so that even if the train encounters an emergency during the driving process, the relevant personnel have more time to react, so as to respond to the unexpected situation in a timely manner, thereby improving the safety of train driving in the station where the fault occurs.

In other embodiments, the speed limit may not be imposed on trains operating normally in the station.

In this embodiment, the judgment module determines whether it is an individual track restriction or an overall station restriction based on the restriction parameters, including S411, judging whether the number of remaining tracks allowed to enter the estimated outage time meets the number of trains that are about to enter the station based on the locations of the problematic tracks, entrances and exits, and switches contained in the restriction parameters; the judgment module first judges the impact on the available tracks based on the locations of the failed entrances and exits and switches, for example, if a switch in the station fails and cannot be used, multiple tracks corresponding to the switch need to be disabled, thereby converting the fault status of the entrances and exits and switches into whether the tracks are available; the judgment module judges whether the number of remaining tracks allowed to enter the estimated outage time meets the number of trains that are about to enter the station.

The number of remaining tracks is obtained by calculating the difference between the total number of tracks N in the station and all the inactive tracks X in the station.

The judgment module first obtains the number of available tracks according to the restriction parameters. For example, there are N tracks in the station. Since X tracks cannot guide trains normally due to various reasons and need to be shut down for maintenance, the number of remaining tracks is N-X. The judgment module then obtains the number of trains Y that will enter the station during the expected shutdown period according to the existing train operation plan.

If the number of remaining tracks N-X is greater than or equal to the number of trains entering the station Y, it is judged as an individual track restriction. At this time, the trains about to enter the station are guided to the remaining available tracks.

If the number of remaining tracks N-X is less than the number of trains entering the station Y, it is judged as an overall restriction of the station. At this time, the train operation plan is adjusted based on the overall restriction of the station.

In this embodiment, the determination module determines the position of the train to enter the station in the original train schedule, including:

S431. The information acquisition module acquires the mileage information of the train that is about to enter the station. The mileage information refers to the mileage that the train has traveled since it departed from the starting station.

S432, the judgment module judges the position of the incoming train according to the mileage information of the incoming train and the position information of each station on the line, and assumes that the train departure station is the origin. Since the train runs on a fixed line, after obtaining the train mileage information, the current position information of the train can be obtained according to the train departure station information and line route information.

In other embodiments, the current position of the train may also be determined by directly acquiring the positioning information of the train.

In this embodiment, the information acquisition module acquires the mileage information of the train that is about to enter the station, including:

S4311. Record the mileage information of the train that is about to enter the station in a dynamic array and pass it to the information acquisition module.

In other embodiments, the mileage information of the train that will enter the station may also be transmitted in the form of a fixed array.

The maximum braking acceleration of the second type of train that the judgment module judges has entered the adjacent section of the station where the fault occurs includes:

S442, the judgment module reads the maximum braking acceleration of the second type of train from the configuration file. The relevant parameters of the train have been stored in the local configuration file. The judgment module searches the configuration file for the relevant parameters of the corresponding train according to the train information to be queried to obtain the maximum braking acceleration of the second type of train.

Obtaining the maximum braking acceleration and braking distance of the second type of train that has entered the adjacent section of the station where the fault occurs includes:

S443. The automatic adjustment module reads a configuration file stored locally.

S444. Obtain corresponding ceiling speed, uniform acceleration and uniform deceleration acceleration from the configuration file according to the train model. The ceiling speed refers to the instantaneous maximum speed during the operation of the train.

S445. Calculate the braking distance of the train according to the ceiling speed, uniform acceleration and uniform deceleration.

After the automatic adjustment module adjusts the train operation plan according to the restriction parameters, it also includes:

S51, judging whether the train operation plan before and after the adjustment has changed. The automatic adjustment module compares whether the train operation plan before and after the adjustment has changed.

S52. If the train operation plan before and after the adjustment is the same, the train operation plan in the train control software is not updated.

The estimated downtime is initially set to 10 minutes, and the estimated downtime is subsequently corrected by obtaining the status of the station equipment. When a device in the station fails, for example, the signal fails and cannot normally guide the train in and out of the station, the information acquisition module obtains that the signal is in an abnormal state, and the parameter generation module generates restriction parameters based on the information. The restriction parameters include the signal abnormality and the estimated downtime of 10 minutes, and send them to other stations and trains on the line. The automatic adjustment module pre-adjusts the train operation plan for the next 10 minutes based on the restriction parameters. If the subsequent equipment status returns to normal, the train operation plan is adjusted accordingly according to the status of the repaired station equipment.

After the information acquisition module acquires the status information of the station equipment, it also includes:

S11. The judgment module judges whether the station equipment is in a normal state or an abnormal state.

In this embodiment, a judgment module is also provided to judge whether the station equipment is in a normal state or an abnormal state. When it is detected that the equipment is in an abnormal state, the information of the abnormal state of the relevant equipment is reported to the station staff at the same time, so that the relevant personnel can know as soon as possible that the current equipment condition in the station is abnormal, so as to take corresponding maintenance measures as soon as possible.

In other embodiments, a judgment module may also be provided to issue an alarm to alert station staff when it is detected that the equipment is in an abnormal state.

S40, after the automatic adjustment module adjusts the train operation plan according to the restriction parameters, it also includes:

S50, the timing module counts the time interval T, and after the time interval T, returns to S10, the information acquisition module acquires the status information of the station equipment.

The timing module counts the time interval T according to whether the station equipment is in normal or abnormal state.

When the station equipment is in a normal state, the time interval T is set to T1, and when the station equipment is in an abnormal state, the time interval T is set to T2, and T1 is greater than T2.

After the time interval T, S10 is executed, and the information acquisition module acquires the status information of the station equipment.

In this embodiment, the time interval between two times when the information acquisition module acquires the station equipment information is adjusted according to the operation status of the station equipment.

In other embodiments, the time interval between two times when the information acquisition module acquires the status information of the station equipment may not be adjusted according to the status of the station equipment.

In this embodiment, T1 is set to 1 minute and T2 is set to 20 seconds. That is, when the station equipment is working normally, the status information of the station equipment is collected every 1 minute; after the station equipment fails, the status information of the station equipment is detected every 20 seconds, so that the automatic acquisition module can obtain the information after the station equipment returns to normal in time, so as to send signals to other stations and trains, so that the line can resume normal operation as soon as possible.

FIG3 shows the automatic adjustment of the train running status based on the station equipment status of this embodiment for the automatic adjustment when the station equipment fails. The running time of the passing trains in the section and station range affected by the station equipment failure is optimized. For the trains that have been dispatched from the previous station of the fault station, they are adjusted to stop in the section, and the trains that have not been dispatched are adjusted to stop in the station at the previous station. The parking time is initially designed to be ten minutes, and the parking time is corrected by adjusting the station equipment status later. By comparing the results before and after the adjustment, it can be observed that the running time of this batch of trains was corrected before and after the station equipment failure, and the trains that have not been dispatched from the previous station were stopped, and the departure time was after the expected fault recovery time. The trains that have been dispatched from the previous station stop in the section, and their departure time is also designed to be after the expected fault recovery time.

The present application also provides a train running state automatic adjustment device based on the station equipment state, the automatic adjustment device is used to implement the train running state automatic adjustment method based on the station equipment state, and the automatic adjustment device includes:

The information acquisition module is used to obtain the equipment information in the station. The information acquisition module is electrically connected to each device in the station and obtains the status information of the station equipment at a certain time interval.

Parameter generation module, the parameter generation module generates restriction parameters according to the station equipment in abnormal state. Restriction parameters are used to describe the available state of the station. For example, when a track fails and cannot be used, the information acquisition module obtains the state information of the failed track. The parameter generation module generates restriction parameters according to the state information obtained by the information acquisition module, such as track failure, expected outage of 10 minutes, and other restriction parameters and sends them to the automatic adjustment module.

Automatic adjustment module, which is used to adjust the train operation plan according to the restriction parameters. After obtaining the restriction parameters of the station equipment, the automatic adjustment module compares the impact of the station fault (such as the track that needs to be deactivated in the next period of time) with the existing train operation plan. If a conflict occurs, such as the original train operation plan needs to use the track that is deactivated due to the fault, the automatic adjustment module adjusts the train operation plan to avoid the train entering the deactivated track.
