Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The control method for train operation provided in this embodiment may be applied in an application environment as shown in fig. 1, where a vehicle-mounted controller of a train communicates with an interlocking device of a target station. Wherein, the vehicle-mounted controller is responsible for finishing the vehicle-mounted ATP/ATO function; the device can be used for controlling the traction, braking and vehicle doors of a train; interlocking means for controlling the switches, routes and signals of the stations and effecting an interlocking relationship therebetween.
In one embodiment, as shown in fig. 2, a method for controlling train operation is provided, and the method is applied to the vehicle-mounted controller of the train in fig. 1, and includes the following steps:
s10: the planned run time of the train to reach the destination is obtained.
The train-mounted controller end is equipment capable of controlling traction, braking and doors of a current train in a train operation control system. The target station is the next station to be reached by the train during the running process. The planned run time is the time expected to be required for the train to reach the destination station. In a particular embodiment, the planned run time may be determined based on the distance between the current location of the train and the next destination station to be reached. When the train starts from one platform, the planned running time of the next target platform reached by the train can be obtained in real time. The closer the distance between the current position of the train and the next destination station is, the less the corresponding planned running time is, and the planned running time of the train reaching the destination station changes in real time along with the running of the train.
S20: and when the planned running time is less than or equal to a preset threshold value, acquiring the platform ID of the target platform and the train grouping information of the train.
The preset threshold is a preset value for detecting whether communication with the interlocking device of the target station is needed to determine the parking point. The station ID is a unique identification preset for each station for identifying a different station. The station ID may be formed in lower case letters, numbers, symbols, or any combination thereof. For example: the station ID may be 0x0001,0x0002 or 0x0003. The train consist information is information indicating whether the train is single consist or double consist. The train consist information may be composed of lower case letters, numbers, symbols, or any combination thereof. The train grouping information corresponding to the different types of grouped trains is different. Typically, a single consist train is typically a train with 8 car groups as a group. The double marshalling train is that 8 carriages are added under the condition that 8 carriages are in one group; the multiplication and the transportation energy are turned over on the basis of the original transportation energy. When the double marshalling operation is carried out, two vehicles have power, and two groups of carriages are controlled by the same vehicle-mounted controller end. In the present embodiment, if the train consist information is 01, the consist of the train is a single consist train, and if the train consist information is 02, the consist of the train is a double consist train.
Specifically, since the station ID of each station and the train consist information of the train have been previously set and stored in a memory module associated with the on-board controller side. Thus, when a train starts from one platform, the planned running time required by the train to reach the next target platform is acquired in real time; and when the planned running time is less than or equal to a preset threshold value, acquiring the platform ID of the target platform and the train grouping information of the train from the storage module.
S30: transmitting a first indication command to the target stationA kind of electronic deviceThe interlock device, the first indication command includes a station ID of the destination station and train consist information of the train.
The first indication command is a command for indicating the interlocking device to determine at which parking spot of the target station the train can park. Specifically, after acquiring the platform ID of the target platform and the train grouping information of the train, the on-board controller side of the train generates a first indication command based on the platform ID of the target platform and the train grouping information of the train, and transmits the first indication command to the target platformA kind of electronic deviceThe interlock device, the first indication command includes a station ID of the destination station and train consist information of the train.
S40: and receiving a feedback instruction returned by the interlocking device based on the first instruction, wherein the feedback instruction comprises a target parking point.
After receiving a first indication command sent by a vehicle-mounted controller end of a train, the interlocking equipment of the target platform analyzes a platform ID and train grouping information contained in the first indication command to determine a target parking point. Such as: the first indication command received by the interlock device is 01 0001 01 0002 (16 in system), then the first 01 is the command ID, then 0001 is the train group number ID, then 01 indicates that the consist of the train is a single consist train, and finally 0002 is the station ID of the destination station to which the train is about to reach.
Wherein, determining the target parking spot according to the first instruction command specifically comprises: firstly, determining optional stopping points of a current target station according to station IDs, wherein one station generally comprises a plurality of optional stopping points, and different stopping points can correspondingly stop trains of different marshalling types; then determining the grouping type of the train through the train grouping information, and determining an alternative parking point which can allow the train of the grouping type to stop from the alternative parking points of the target platform according to the grouping type of the train after determining the grouping type of the train; acquiring platform door fault information of each alternative parking point; and finally, according to the platform door fault information of each alternative parking point, determining the parking point with the least number of the fault platform doors from the alternative parking points as a target parking point.
After the interlocking device of the target platform determines the target parking point of the train at the target platform, generating a feedback instruction containing the target parking point based on the target parking point, and returning the feedback instruction containing the target parking point to the vehicle-mounted controller end of the train, wherein the vehicle-mounted controller end receives the feedback instruction returned by the interlocking device based on the first instruction command. Such as: after the interlock device selects a target stopping point for the train 0001 (assuming that the target stopping point 2 is the stopping point of the train at the target station 0002), a feedback command 02 0001 02 is sent to the vehicle-mounted controller end of the train, wherein the first 02 is a response command ID of a 01 command, 0001 represents a train group number ID, and the last 02 represents the target stopping point 2.
S50: and determining a target train door to be opened in the train based on the target stopping point.
Specifically, corresponding train doors in the train are determined according to openable platform doors in a target parking spot, one platform door is correspondingly opened, and a plurality of platform doors are usually included in one parking spot, namely, a plurality of target train doors to be opened in the train are also included in the train. In one embodiment, if no failed platform door exists in the target parking spot, and the number of preset platform doors in the target parking spot is the same as the number of train doors and corresponds to one, all doors in the train can be determined as the target train doors to be opened.
S60: and sending a second instruction command to the interlocking equipment corresponding to the target platform so as to instruct the interlocking equipment to control the platform door of the target parking spot, wherein the second instruction command comprises the target parking spot and the door ID of the target train door.
Wherein the second instruction command is a command for instructing the interlock device to execute the state of the platform door controlling the target parking spot. Specifically, after determining the target train doors to be opened in the train, the vehicle-mounted controller side acquires the door IDs of the target train doors, generates a second indication command according to the target parking points and the door IDs of the target train doors, and sends the second indication command to the interlocking equipment corresponding to the target platform so as to instruct the interlocking equipment to control the platform doors of the target parking points, and the interlocking equipment of the target platform controls the corresponding platform doors in the target parking points to execute opening or closing operation. Such as: when the on-board controller end of the train judges that no other trains exist between the current position of the train and the target parking spot 0002, a second instruction command is sent to the interlocking equipment of the target platform, for example 03 0001 0002 02, wherein 03 is a platform display command ID,0001 is a train group number ID,0002 is a parking platform ID, and the last 02 is the parking spot of the train at the platform.
S70: and updating the running route of the train according to the target stopping point.
Specifically, after receiving a feedback instruction including a target parking point returned by the interlocking device based on the first instruction command, the vehicle-mounted controller firstly judges whether the target parking point is consistent with a preset parking point preset by the system, and if the target parking point is inconsistent with the preset parking point, the vehicle-mounted controller updates the running route of the train according to the target parking point, namely, the vehicle-mounted controller changes the running route of the train into a place about to arrive at the parking point, and controls the train to run to the target parking point for parking. In another embodiment, if the target stopping point is consistent with the preset stopping point preset by the system, the train is continuously controlled to run to the preset stopping point (target stopping point) for stopping according to the original route. Such as: if the vehicle-mounted controller end of the train 0001 receives a feedback instruction returned by the interlocking equipment, 02 0001 02, the running route of the train is updated according to the analyzed stopping point 2, and the train is controlled to run to the platform 0002.
In this embodiment, the planned running time of the train to reach the destination station is acquired; when the planned running time is less than or equal to a preset threshold value, acquiring a platform ID of a target platform and train grouping information of a train; transmitting a first indication command to the interlocking device corresponding to the target station, wherein the first indication command comprises a station ID of the target station and train grouping information of a train; receiving a feedback instruction returned by the interlocking equipment based on the first instruction, wherein the feedback instruction comprises a target parking spot; determining a target train door to be opened in the train based on the target stopping point; transmitting a second instruction command to interlocking equipment corresponding to a target platform so as to instruct the interlocking equipment to control a platform door of the target parking spot, wherein the second instruction command comprises a target parking spot and a door ID of a target train door; updating the running route of the train according to the target stopping point; by adopting the method of pre-selecting the stop point of the train at the next platform, the situation that the platform has a fault platform door is avoided, and the operation of the platform door fault alignment isolation door is reduced, so that the operation efficiency of the system is improved.
In one embodiment, after obtaining the planned running time of the train reaching the destination station, the control method for the train running further specifically includes the following steps:
and when the planned running time is greater than a preset threshold value, determining the default parking point of the target platform as a target parking point.
The default stopping point is a stopping point preset for the train. When the planned running time is greater than the preset threshold value, the default parking point of the target platform is determined as the target parking point, so that the time interval between the time point of determining the target parking point of the target platform and the time point of parking at the target platform is as short as possible, and the state of the platform door corresponding to the target parking point is prevented from changing after the target parking point is determined. However, the time interval between the time point of determining the target stop point of the target station and the time point of stopping at the target station cannot be too short, and the too short time interval may lead to the fact that the subsequent communication is not coordinated, and the train is approaching the target station.
In an embodiment, as shown in fig. 3, before determining a target train door to be opened in the train based on the target stopping point, the control method for train operation further specifically includes the following steps:
s41: and detecting whether other trains exist between the current position of the train and the target parking spot.
Specifically, in order to avoid the situation that two trains simultaneously travel at the same target stopping point in the same time period, after the travel route of the train is updated according to the target stopping point, whether other trains exist between the current position of the train and the target stopping point is detected, so that the operation efficiency of the system is further improved.
S42: and if no other trains exist between the current position of the train and the target stopping point, executing the step of determining the target train door to be opened in the train based on the target stopping point.
Specifically, if no other trains exist between the current position of the train and the target parking spot, a step of determining the target train doors to be opened in the train based on the target parking spot is executed, namely, the corresponding train doors in the train are determined according to the platform doors which can be opened in the target parking spot. In one embodiment, if no failed platform door exists in the target parking spot, and the number of preset platform doors in the target parking spot is the same as the number of train doors and corresponds to one, all doors in the train can be determined as the target train doors to be opened.
In the embodiment, whether other trains exist between the current position of the train and the target parking spot or not is detected; if no other trains exist between the current position of the train and the target stopping point, executing a step of determining a target train door to be opened in the train based on the target stopping point; before a target train door to be opened in a train is determined based on a target parking spot, whether other trains exist between the current position of the train and the target parking spot is detected, so that the condition that two trains simultaneously travel the same target parking spot in the same time period is avoided, and the running efficiency of the system is further improved.
In an embodiment, after detecting whether there is another train between the current position of the train and the target stopping point, the control method for running the train further specifically includes the following steps:
and if other trains exist between the current position of the train and the target stopping point, controlling the train to enter an emergency driving mode.
The emergency driving mode is a mode for controlling the train to drive to a target parking spot at a speed within a preset speed limit range. Specifically, when other trains exist between the current position of the train and the target stopping point, the train is controlled to enter an emergency running mode so as to reduce the speed of the train without affecting the normal running of the other trains, so that the flexibility of train dispatching is improved and the running efficiency of the train is improved.
In one embodiment, as shown in fig. 4, after updating the running route of the train according to the target stopping point, the control method for running the train further specifically includes the following steps:
s80: and after the train enters the target platform, determining the current distance between the train and the target parking spot.
Specifically, after a train enters a target station, a signal detection device arranged on the train receives a pulse signal of a positioning synchronization point, and determines the current distance between the train and a target stopping point according to the pulse signal of the positioning synchronization point. In practical application, at least 4 positioning synchronization points are paved on the track in the station in advance, the positioning synchronization points adopt a mode of crossing the synchronization points, and the specific number is determined according to the distance between the entrance of the target station and the target parking point.
S90: and calculating a recommended speed corresponding to the current distance by using a train control algorithm according to the current distance between the train and the target parking spot, and adjusting the current speed of the train.
Specifically, in the running process of the train, a recommended curve is calculated in real time by utilizing a train control algorithm according to the distance between the train and the target parking spot, wherein the recommended curve is a corresponding relation curve between the current distance between the train and the target parking spot and the recommended speed. And determining the recommended speed corresponding to the current distance between the train and the target parking spot in the recommended curve. After the recommended speed is determined, a fuzzy control algorithm is adopted to adjust the current speed of the train so as to ensure that the deviation between the current speed and the recommended speed of the train is within an error allowable range. The adjustment process may be: if the current speed is greater than the recommended speed and exceeds the allowable error range, applying a corresponding braking gear to the train; and if the deviation between the current speed and the recommended speed is within the allowable error range, the train is coasted.
In one embodiment, as shown in fig. 5, an example of the method applied to the interlocking device of the destination station in fig. 1 is illustrated, and the method includes the following steps:

Wherein the parking spot determination information is information for determining a target parking spot in the target station. When the planned running time of the train reaching the target station is smaller than or equal to a preset threshold value, the vehicle-mounted controller of the train establishes communication with the interlocking equipment of the target station and sends a first indication command to the interlocking equipment of the target station, and the interlocking equipment receives the first indication command sent by the vehicle-mounted controller of the train, wherein the first indication command comprises parking point determination information.
S22: and determining a target parking spot in the target station according to the parking spot determination information.
After receiving the parking spot determination information contained in the first indication command sent by the vehicle-mounted control of the train, determining the target parking spot in the target station according to the parking spot determination information. Firstly, determining an optional parking point of a target station according to a station ID of the target station in parking point determination information, and then determining a train grouping type according to train grouping information in the parking point determination information; further determining an alternative parking point from the alternative parking points according to the grouping type of the train; and finally, determining a target parking point from the candidate parking points according to the acquired platform door fault information of each candidate parking point.
S23: and sending a feedback instruction to the vehicle-mounted controller, wherein the feedback instruction comprises the target parking spot.
S24: and receiving a second instruction command returned by the vehicle-mounted controller based on the feedback instruction, and controlling the platform door of the target parking spot based on the second instruction command.
Specifically, after determining a target parking spot in a target platform, the interlocking device generates a feedback instruction based on the target parking spot and sends the feedback instruction to a vehicle-mounted controller of the train, the feedback instruction comprises the target parking spot, and receives a second instruction command returned by the vehicle-mounted controller based on the feedback instruction, and controls a platform door of the target parking spot based on the second instruction command.
In this embodiment, when the planned running time of the train reaching the destination station is less than or equal to a preset threshold, a first instruction command sent by a vehicle-mounted controller of the train is received, where the first instruction command includes parking spot determination information; determining a target parking spot in the target station according to the parking spot determination information; sending a feedback instruction to the vehicle-mounted controller, wherein the feedback instruction comprises a target parking spot; receiving a second instruction command returned by the vehicle-mounted controller based on the feedback instruction, and controlling a platform door of the target parking spot based on the second instruction command; thereby improving the efficiency and accuracy of train operation control.

s221: an optional parking point for the target station is determined based on the station ID of the target station.
The selectable parking points are parking points which can be parked in a preset target platform. Typically each station includes at least two selectable stop points. The number and positions of the optional parking points corresponding to different stations are different. Specifically, the interlock device, after acquiring the station ID of the target station, may determine the corresponding associated optional parking point directly from the station ID.
S222: the train consist type is determined from the train consist information.
The train grouping information is information for indicating whether the train is single-grouped or double-grouped. The train grouping information corresponding to the different types of grouped trains is different. In the present embodiment, the group types of trains mainly include a single group train and a double group train. The interlocking device of the target station can determine the grouping type of the train according to the train grouping information after receiving the train grouping information of the train returned by the vehicle-mounted controller side of the train. For example: if the train consist information is 01, it indicates that the consist type of the train is a single consist train, and if the train consist information is 02, it indicates that the consist type of the train is a double consist train.

Thus, in this step, an alternative stop point is first determined from the alternative stop points according to the group type of the train. For example: if the group type of the train is a double group train, a stop point where only the double group train can be stopped and a stop point where both the single group train and the double group train can be stopped need to be determined as an alternative stop point from among the alternative stop points.

Wherein the station door failure information is information indicating whether the station door has a failure. Specifically, the interlock device, after determining the candidate parking spots, obtains the platform door fault information of each candidate parking spot from the platform door monitoring system associated with the candidate parking spot. In one embodiment, the platform door monitoring system monitors in real time whether each platform door in all parking spots is in a normal state, and feeds back the monitoring result to the interlocking device. If one or a plurality of platform doors are in fault, the platform door monitoring system sends corresponding platform door fault information to the interlocking device, so that the interlocking device can determine the platform doors with faults at the stopping points through the platform door fault information.
S225: and determining a target parking spot from the alternative parking spots according to the platform door fault information of each alternative parking spot.

In another embodiment, if there are no faulty platform doors in all of the alternative stops, i.e. all of the platform doors in all of the alternative stops are faulty, the closest or furthest from the train is determined as the target platform door. Likewise, if more than one alternative stopping point with the least number of the fault platform doors is determined, selecting the stopping point closest to or farthest from the train from the alternative stopping points with the least number of the fault platform doors as the target platform door.
In this embodiment, the optional parking point of the target station is determined based on the station ID of the target station; determining the grouping type of the train through the train grouping information; determining an alternative parking point from the alternative parking points according to the grouping type of the train; acquiring platform door fault information of each alternative parking point; determining a target parking point from the candidate parking points according to the platform door fault information of each candidate parking point; therefore, the number of the failed platform doors in the determined target parking spot is minimum or no failed platform doors exist, the operation of the platform door fault alignment isolation doors is reduced, and the operation efficiency of the system is improved.
In one embodiment, as shown in fig. 7, according to the platform door fault information of each alternative parking point, a target parking point is determined from the alternative parking points, and specifically includes the following steps:

Specifically, the obtained platform door fault information includes information indicating whether the corresponding alternative parking point has a fault platform door or not, and specifically how many fault platform doors are present. Therefore, after the platform door fault information of each alternative parking point is obtained, the number of the fault platform doors of each alternative parking point can be determined according to the platform door fault information of each alternative parking point.
S2252: if the number of the failed platform doors of each alternative parking point is different, the alternative parking point with the least number of the failed platform doors is determined as the target parking point.
In one embodiment, if the number of failed platform doors is different for each of the alternative stops, the alternative stop with the least number of failed platform doors is determined as the target stop. Illustratively: if the alternative parking spot 1 comprises platform doors 1, 2, 3 and 4, the alternative parking spot 2 comprises platform doors 5, 6, 7 and 8, the interlocking equipment judges that the platform doors 1, 2, 3 and 4 have no platform door faults, and the platform doors 5, 6, 7 and 8 have the platform door faults, the interlocking equipment selects the alternative parking spot 1 as a target parking spot of the train at a target platform; if there is a platform door failure in the platform doors 1, 2, 3, 4 and no platform door failure in the platform doors 5, 6, 7, 8, the interlock device selects the alternative stop point 2 as the target stop point for the train at the target platform. If the interlocking equipment judges that the platform doors 1, 2, 3 and 4 have platform door faults and the platform doors 5, 6, 7 and 8 have platform door faults, the interlocking equipment compares the number of the platform doors with faults in the platform doors 1, 2, 3 and 4 of the alternative parking point 1 with the number of the platform doors with faults in the platform doors 5, 6, 7 and 8 of the alternative parking point 2, and if the number of the platform doors with faults in the platform doors 1, 2, 3 and 4 of the alternative parking point 1 is less, the interlocking equipment selects the alternative parking point 1 as a target parking point of the train at a target platform; if the number of the station doors 5, 6, 7, 8 of the alternative stop point 2 is small, the alternative stop point 2 is selected as the target stop point of the train at the target station.
S2253: if the number of failed platform doors of each alternative parking point is the same, the first alternative parking point is determined as the target parking point.
The first alternative parking point may be a preferred parking point set in advance according to actual conditions. Such as: the first alternative parking spot may be a parking spot closest to the train, a parking spot farthest from the train, a parking spot default in advance for the system, or the like. In one embodiment, if the number of failed platform doors for each alternate parking spot is the same, the first alternate parking spot is determined to be the target parking spot.
