Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for controlling train operation according to this embodiment can be applied to the application environment shown in fig. 1, in which an on-board controller of a train communicates with an interlocking device of a target platform. Wherein, the vehicle-mounted controller is responsible for completing the vehicle-mounted ATP/ATO function; the device can be used for controlling the traction, the braking and the door of the train; the interlocking device is a device for controlling the turnout, access and signal of the station and realizing the interlocking relationship between the turnout, the access and the signal.
In an embodiment, as shown in fig. 2, a method for controlling train operation is provided, which is described by taking an example that the method is applied to an on-board controller of the train in fig. 1, and includes the following steps:
s10: and acquiring the planned running time of the train reaching the target platform.
The train-mounted controller end of the train is equipment which can control the traction, the brake and the train door of the current train in a train operation control system. The target platform is the next platform to be reached by the train in the driving process. The planned operating time is the time expected to be required for the train to reach the target platform. In one embodiment, the planned operation time may be determined based on the distance between the current location of the train and the next target platform to be reached. When the train departs from one platform, the planned operation time of the next target platform where the train arrives can be obtained in real time. The closer the distance between the current position of the train and the next target platform is, the less the corresponding required planning operation time is, and the planning operation time of the train reaching the target platform changes in real time along with the running of the train.
S20: and when the planning operation time is less than or equal to a preset threshold value, acquiring the platform ID of the target platform and the train formation information of the train.
The preset threshold is a value preset to detect whether communication with the interlock device of the target station is required to determine the parking point. The sta ID is a unique identifier preset for each sta to identify different stas. The station ID may be composed of upper and lower case letters, numbers, symbols, or any combination thereof. For example: the station ID may be 0x0001, 0x0002, or 0x 0003. The train consist information is information for indicating whether the train is a single consist or a double consist. The train consist information may be composed of upper and lower case letters, numbers, symbols, or any combination thereof. The train formation information corresponding to different types of formation trains is different. Typically, a single consist train is a train with a set of 8 cars. The double-marshalling train is characterized in that 8 carriages are added under the condition that one set of 8 carriages is adopted; namely, the operation capacity is doubled and increased on the basis of the original operation capacity. When the double-marshalling operation is carried out, both vehicles have power, and the two groups of carriages are controlled by the same vehicle-mounted controller. In the present embodiment, the train formation information indicates that the train formation is a single-formation train if 01, and indicates that the train formation is a double-formation train if 02.
Specifically, the station ID of each station and the train configuration information of the train are preset and stored in the storage module associated with the on-board controller. Therefore, when the train starts from one platform, the planned operation time required by the train to reach the next target platform is acquired in real time; and when the planning running time is less than or equal to a preset threshold value, acquiring the platform ID of the target platform and the train formation information of the train from the storage module.
S30: sending a first indication command to a target station corresponding to the target stationIs/are as followsAnd an interlock device, the first indication command including the platform ID of the target platform and train consist information of the train.
The first instruction command is a command for instructing the interlocking device to determine at which stop point of the target platform the train can stop. Specifically, the on-board controller of the train acquires the platform ID of the target platform and the train formation information of the train, and then bases the operation on the platform ID and the train formation informationThe station ID of the target station and the train formation information of the train generate a first instruction command, and the first instruction command is transmitted to the target stationIs/are as followsAnd an interlock device, the first indication command including the platform ID of the target platform and train consist information of the train.
S40: and receiving a feedback instruction returned by the interlocking device based on the first indication command, wherein the feedback instruction comprises a target parking point.
After receiving a first instruction command sent by an on-board controller of a train, the interlocking device of the target platform analyzes the platform ID and the train formation information included in the first instruction command, and determines a target stop point. Such as: the first indication command received by the interlock is 010001010002 (16 th system representation), then its first 01 is the command ID, then 0001 is the train consist ID, then 01 indicates that the train is being formed as a single consist train, and finally 0002 is the platform ID of the target platform to which the train will arrive.
The step of determining the target parking spot according to the first instruction command specifically comprises the following steps: firstly, determining selectable stopping points of a current target platform according to the platform ID, wherein one platform usually comprises a plurality of selectable stopping points, and different stopping points may correspondingly stop trains of different formation types; determining the train formation type of the train through the train formation information, and determining an alternative stop point which can allow the train of the train formation type to stop from the optional stop points of the target platform according to the train formation type after determining the train formation type; and acquiring platform door fault information of each alternative parking spot; 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 as the target parking point from the alternative parking points.
After the interlocking device of the target platform determines the target stopping point of the train at the target platform, a feedback instruction containing the target stopping point is generated based on the target stopping point, the feedback instruction containing the target stopping point is returned to the vehicle-mounted controller end of the train, and 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 selected target stopping point 2 is the stopping point of the train at the target platform 0002), a feedback command 02000102 is sent to the on-board controller end of the train, the first 02 is the response command ID of the 01 command, 0001 indicates the train group number ID, and the last 02 indicates the target stopping point 2.
S50: and determining a target train door to be opened in the train based on the target stop point.
Specifically, the corresponding train door in the train is determined according to the platform doors which can be opened in the target stop point, one platform door is opened correspondingly, and one stop point usually comprises a plurality of platform doors, namely, a plurality of target train doors which need to be opened in the train are also provided. In one embodiment, if there is no faulty station door in the target stop, and the number of station doors preset in the target stop is the same as the number of train doors, and the station doors correspond to the train doors one by one, all the train doors can be determined as the target train doors to be opened.
S60: and sending a second indication command to the interlocking device corresponding to the target platform to indicate the interlocking device to operate and control the platform door of the target stopping point, wherein the second indication command comprises the vehicle door ID of the target stopping point and the vehicle door of the target train.
Wherein the second indication command is a command for instructing the interlock device to execute the platform door state of the control target parking point. Specifically, after determining target train doors to be opened in the train, the vehicle-mounted controller acquires a door ID of each target train door, generates a second indication command according to the target stop point and the door ID of each target train door, and sends the second indication command to the interlocking device corresponding to the target platform, so as to indicate the interlocking device to operate and control the platform door of the target stop point, so that the interlocking device of the target platform controls the corresponding platform door in the target stop point to perform opening or closing operation. Such as: when the on-board controller of the train determines that there is no other train between the current position of the train and the target stop point 0002, a second instruction command is sent to the interlocking device of the target platform, such as 030001000202, where 03 is the platform display command ID, 0001 is the train group number ID, 0002 is the stop platform ID, and the last 02 is the stop point 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 which is returned by the interlocking device and contains a target stop point based on the first instruction command, the vehicle-mounted controller firstly judges whether the target stop point is consistent with a preset stop point preset by the system, and if the target stop point is inconsistent with the preset stop point, the vehicle-mounted controller updates the running route of the train according to the target stop point, namely, the target stop point is changed to be a place to be reached to stop, and the train is controlled to run to the target stop point to stop. In another embodiment, if the target stop point is consistent with the preset stop point preset by the system, the train is continuously controlled to travel to the preset stop point (target stop point) to stop according to the original route. Such as: if the feedback instruction returned by the interlocking device received by the vehicle-mounted controller end of the train 0001 is 02000102, 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 the embodiment, the planned operation time of the train reaching the target platform is obtained; when the planning operation time is less than or equal to a preset threshold value, acquiring a platform ID of a target platform and train formation information of a train; sending a first instruction command to interlocking equipment corresponding to a target platform, wherein the first instruction command comprises a platform ID of the target platform and train formation information of a train; receiving a feedback instruction returned by the interlocking device based on the first indication command, wherein the feedback instruction comprises a target parking point; determining a target train door to be opened in the train based on the target stop point; sending a second indication command to interlocking equipment corresponding to a target platform to indicate the interlocking equipment to control a platform door of the target parking point, wherein the second indication command comprises a target parking point and a vehicle 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 selecting the stop point of the train at the next platform in advance, the condition that the platform door fails at the platform is avoided, and the operation of fault alignment and isolation of the platform door is reduced, so that the operation efficiency of the system is improved.
In an embodiment, after obtaining the planned operation time for the train to reach the target platform, the method for controlling the train operation further includes the following steps:
and when the scheduled operation time is greater than a preset threshold value, determining the default parking point of the target platform as the target parking point.
The default stopping point is a stopping point preset for the train. And when the planned running time is greater than a preset threshold value, determining the default parking point of the target platform 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 condition 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 platform and the time point of stopping at the target platform cannot be too short, and the too short time interval may cause that the train approaches the target platform before the subsequent communication coordination.
In an embodiment, as shown in fig. 3, before determining a target train door to be opened in the train based on the target stop point, the method for controlling train operation further includes the following steps:
s41: and detecting whether other trains exist between the current position of the train and the target stop point.
Specifically, in order to avoid the situation that two trains simultaneously drive the same target stop point in the same time period, after the driving route of the train is updated according to the target stop point, whether other trains exist between the current position of the train and the target stop point needs to be detected, so that the operation efficiency of the system is further improved.
S42: and if no other train exists between the current position of the train and the target stopping point, determining a target train door needing to be opened in the train based on the target stopping point.
Specifically, if it is detected that no other train exists between the current position of the train and the target stop point, the step of determining the target train door to be opened in the train based on the target stop point is executed, that is, the corresponding train door in the train is determined according to the platform door which can be opened in the target stop point. In one embodiment, if there is no faulty station door in the target stop, and the number of station doors preset in the target stop is the same as the number of train doors, and the station doors correspond to the train doors one by one, all the train doors 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 stop point is detected; if no other train exists between the current position of the train and the target stopping point, determining a target train door needing to be opened in the train based on the target stopping point; before determining a target train door needing to be opened in a train based on a target stop point, whether other trains exist between the current position of the train and the target stop point is detected, so that the condition that two trains run at the same target stop point in the same time period is avoided, and the operation 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 stop point, the method for controlling train operation further includes the following steps:
and if other trains exist between the current position of the train and the target stop 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 stop point at a speed within a preset speed limit range. Specifically, when other trains exist between the current position of the train and the target stop point, the train is controlled to enter an emergency driving mode so as to reduce the speed of the train without influencing the normal operation of other trains, so that the flexibility of train scheduling is improved, and the operation efficiency of the train is improved.
In an embodiment, as shown in fig. 4, after the driving route of the train is updated according to the target stopping point, the method for controlling train operation further includes the following steps:
s80: and after the train enters the target platform, determining the current distance between the train and the target stop point.
Specifically, after the train enters the target platform, the signal detection device arranged on the train receives the pulse signal of the positioning synchronization point, and the current distance between the train and the target stop point is determined according to the pulse signal of the positioning synchronization point. In practical application, at least 4 positioning synchronization points are paved on a track in a station in advance, the positioning synchronization points adopt a cross synchronization point mode, and the specific number is determined according to the distance between an entrance of a target platform and a target parking point.
S90: and calculating the recommended speed corresponding to the current distance by using a train control algorithm according to the current distance between the train and the target stop point, 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 using a train control algorithm according to the distance between the train and the target stop point, and the recommended curve is a corresponding relation curve of the current distance between the train and the target stop point and the recommended speed. And determining the recommended speed corresponding to the current distance between the train and the target stop point in the recommended curve. And after the recommended speed is determined, adjusting the current speed of the train by adopting a fuzzy control algorithm so as to ensure that the deviation between the current speed of the train and the recommended speed 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 brake gear to the train; and if the deviation of the current speed and the recommended speed is within the allowable error range, the train performs coasting.
In one embodiment, as shown in fig. 5, the interlocking device of the target station in fig. 1 is used as an example to explain the method, which includes the following steps:
s21: when the planned running time of the train reaching the target platform is less than or equal to a preset threshold value, receiving a first instruction command sent by an on-board controller of the train, wherein the first instruction command comprises parking point determination information.
Wherein the parking spot determination information is information for determining a target parking spot in the target platform. When the planned operation time of the train reaching the target platform is less than or equal to the preset threshold value, the vehicle-mounted controller of the train establishes communication with the interlocking device of the target platform and sends a first indication command to the interlocking device of the target platform, the interlocking device receives the first indication command sent by the vehicle-mounted controller of the train, and the first indication command comprises the parking point determination information.
S22: and determining a target parking point in the target platform according to the parking point determination information.
After receiving the stop point determination information included in the first instruction command transmitted by the on-board control of the train, determining a target stop point in the target platform according to the stop point determination information. Firstly, determining optional parking points of a target platform according to the platform ID of the target platform in the parking point determination information, and then determining the train formation type of the train according to the train formation information in the parking point determination information; further determining alternative stopping points from the alternative stopping points according to the grouping type of the train; and finally, determining a target parking point from the alternative parking points according to the acquired platform door fault information of each alternative parking point.
S23: and sending a feedback instruction to the vehicle-mounted controller, wherein the feedback instruction comprises a target parking point.
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 a target stop point in a target platform is determined, the interlocking device generates a feedback instruction based on the target stop point, sends the feedback instruction to an on-board controller of the train, wherein the feedback instruction comprises the target stop point, receives a second instruction command returned by the on-board controller based on the feedback instruction, and controls a platform door of the target stop point based on the second instruction command.

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

In one embodiment, the platform door monitoring system monitors whether the state of each platform door in all parking spots is normal in real time and feeds back the monitoring result to the interlocking device. If one or a plurality of platform doors have faults, the platform door monitoring system sends the fault information of the corresponding platform doors to the interlocking equipment, so that the interlocking equipment can determine the platform doors with the faults at the parking points through the fault information of the platform doors.
S225: and determining a target parking point from the alternative parking points according to the platform door fault information of each alternative parking point.

Therefore, after the platform door fault information of each candidate parking point is acquired, the parking point with the least number of the fault platform doors is determined as the target parking point according to the platform door fault information of each candidate parking point.
In another embodiment, if there is no faulty platform door in all the alternative stopping points, i.e. all the platform doors in all the alternative stopping points are not faulty, the stopping point closest or farthest to the train is determined as the target platform door. Similarly, if more than one candidate parking point with the least number of the failed platform doors is determined, the parking point closest to or farthest from the train is selected from the candidate parking points with the least number of the failed platform doors to be determined as the target platform door.

Specifically, the obtained platform door fault information includes information indicating whether a fault platform door exists at the corresponding candidate parking spot, and specifically how many fault platform doors exist. 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.
