Abstract
Description
Technical Field
[0001] This application relates to the field of rail transit technology, and in particular to a method, device, equipment, and storage medium for controlling platform screen doors in virtual train formation operation. Background Technology
[0002] To meet the operational demands of green and low-carbon development, efficient resource utilization, and cost reduction and efficiency improvement, while also addressing the issue of uneven spatial and temporal distribution, virtual flexible train formation (hereinafter referred to as virtual formation) has become an important research direction in rail transit. Virtual formation does not rely on mechanical connection devices, but instead uses technologies such as wireless communication and automatic control to "couple" multiple trains (including two trains) at sufficiently small intervals to operate in formation. Moreover, this coupling can be dynamically "uncoupled" online as needed, thereby significantly improving the efficiency and flexibility of train formation adjustments.
[0003] The key technology of virtual train formation is the use of a train safety protection method based on relative braking distance (commonly known as "hitting a soft wall"). In this method, the following train can make full use of the operating status information such as the position, speed, and acceleration of the preceding train. It also considers the track resources dynamically released by the following train during braking as the preceding train continues to move forward, and incorporates the aforementioned track resources that will only be dynamically released by the preceding train in the future into the protection speed calculation process for the following train, thereby shortening the train following distance.
[0004] However, the virtual train formation operation mode differs from the existing fixed train formation operation mode. When two trains stop at a station, there should be a platform door between them to maintain the effective alignment of the train doors (i.e., the actual train doors used for passenger boarding and alighting during train operation) and platform doors under the premise of virtual formation mode, facilitating passenger boarding and alighting. The platform door control strategy required by this need is more precise than that for existing fixed train formations, and currently there is no platform door control scheme specifically for this virtual train formation operation mode.

[0047] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0048] In developing this application, the inventors discovered that the virtual train formation operation mode differs from the existing fixed train formation operation mode. When two trains stop at a station, there should be a platform door between them to maintain the effective alignment of the train doors (i.e., the actual train doors used for passenger boarding and alighting during train operation) and platform doors under the premise of virtual train formation, thus facilitating passenger boarding and alighting. The platform door control strategy resulting from this requirement is more precise than that for existing fixed train formations, and currently there is no platform door control scheme specifically for this virtual train formation operation mode.
[0049] To address the aforementioned issues, this application provides a method, apparatus, device, and storage medium for controlling platform screen doors in virtual train formation operation. The virtual train formation includes at least one set of minimum group units, each minimum group unit comprising at least one train. Each platform includes at least one set of first logical platform screen doors, each set comprising multiple consecutive platform screen doors, with no overlap between the doors in each set of first logical platform screen doors. Each first logical platform screen door uniquely corresponds to a minimum group unit, and the number of doors in the first logical platform screen door is the total number of train doors in all trains included in its corresponding minimum group unit. Each platform includes at least one set of second logical platform screen doors, with no overlap between the doors in each set of second logical platform screen doors. The second logical platform screen door uniquely corresponds to a minimum group unit, and the number of platform screen doors in the second logical platform screen door is the total number of valid train doors of all trains included in its corresponding minimum group unit. The valid train doors of a train are those used for passenger boarding and alighting. Any platform screen door in any group of first logical platform screen doors may be the same as or different from any platform screen door in any group of second logical platform screen doors. The method includes: the onboard controller continuously determining the closed and locked state of each group of first logical platform screen doors at the target platform; if the closed and locked state of each group of logical platform screen doors is closed and locked, and the virtual train has stopped accurately after entering the station, the onboard controller controls the opening and closing of the second logical platform screen doors corresponding to each minimum group unit. The method provided in this application achieves precise control of platform screen doors in virtual train formation mode by precisely controlling the second logical platform screen doors based on the closed and locked state of the first logical platform screen doors.
[0050] During operation, trains are configured according to actual operational needs, such as single 4-car formations, 4+4 mechanical formations, 4+4 virtual formations, or other forms of formation. Different formation types present different scenarios for alignment and stopping at the platform.
[0051] like Figure 1 This shows the relationship between the train doors and platform doors when a single 4-car train is stopped. Figure 2 This illustrates the relationship between the train doors and platform doors when a 4+4 mechanical trainset stops. Figure 3 The diagram illustrates the relationship between train doors and platform doors when a 4+4 virtual train formation stops. For other train formation configurations, the relationship between train doors and platform doors during stopping is not illustrated; please refer to the actual situation.
[0052] As shown in the diagram above, during operation, multiple trains form a minimum group unit. Further adjustments are made to the minimum group unit based on actual operational needs. For example... Figure 1 , Figure 2 , Figure 3 As shown, the smallest group unit consists of 4 trains. Figure 1The smallest single unit in the process becomes a group for operation, while Figure 2 and Figure 3 In the middle, it involves grouping the two smallest groups of units (where, Figure 2 The two smallest unit groups are assembled in a mechanical assembly manner. Figure 3 The two smallest units are grouped together virtually and then run.
[0053] Each train includes multiple train doors, such as Figure 1 , Figure 2 , Figure 3 The train shown has five doors. When the train stops, each door uniquely corresponds to a platform door, and passenger boarding and alighting are completed through the linkage between the train door and the corresponding platform door. However, during train operation, not all doors on the train need to be used for passenger boarding and alighting. Figure 3 The last train door of the last carriage in the train is not used for passenger boarding and alighting. Therefore, in this embodiment and subsequent embodiments, the train door used for passenger boarding and alighting is referred to as the effective train door.
[0054] As explained above, a virtual train formation includes at least one smallest train unit, and each smallest train unit includes at least one train. The valid doors of a train are the doors used for passenger boarding and alighting.
[0055] Based on the aforementioned characteristics of train operation, this application first refines the platform doors. According to the number of train doors in the smallest group unit, the platform doors on the platform are grouped. Each group includes multiple consecutive platform doors, and the number of platform doors is the same as the total number of train doors in the smallest group unit. Each group of platform doors is denoted as a first logical platform door group. For example... Figure 1 , Figure 2 , Figure 3 The smallest group unit shown includes four trains, each with five doors. Therefore, a smallest group unit includes 4 × 5 = 20 doors. Correspondingly, the platform doors on the platform are also grouped, with each group consisting of 20 consecutive doors. Thus, each group of platform doors is the first logical platform door. For example... Figure 4 As shown, it includes two sets of first logic platform gates, namely PSD1-1 and PSD1-2, with each set of first logic platform gates comprising 20 platform gates. Each set of first logic platform gates corresponds to a set of the smallest group units.
[0056] It should be noted that the first logical platform door only corresponds one-to-one with all the train doors included in the smallest group unit, and does not involve whether the train door is a valid train door. That is to say, if only 19 of the 20 train doors in a smallest group unit are valid train doors and the remaining train door is not a valid train door, then the first logical platform door will also include 20 consecutive platform doors.
[0057] As explained above, each platform includes at least one set of first logical platform screen doors, wherein each first logical platform screen door comprises multiple consecutive platform screen doors, and the platform screen doors in each set of first logical platform screen doors do not overlap. Each first logical platform screen door uniquely corresponds to a smallest group unit, and the number of platform screen doors in the first logical platform screen door is the total number of train doors of all trains included in its corresponding smallest group unit.
[0058] Simultaneously, based on the total number of valid train doors in the trains included in the smallest group unit, the platform doors on the platform are grouped. Each group includes multiple consecutive platform doors, with the number of platform doors being the same as the total number of valid train doors in the trains included in the smallest group unit. Each group of platform doors is denoted as a second logical platform door group, and the second logical platform door corresponds to the stopping position of its corresponding smallest group unit. In other words, during operation, the second logical platform door is linked with the train doors of its corresponding smallest group unit to facilitate passenger boarding and alighting. Figure 1 The smallest group unit shown includes four trains, each with five doors. Therefore, a set of smallest group units comprises 4 × 5 = 20 doors, and all doors are valid. If this smallest group unit uses a centering stop scheme (stopping in the middle of the platform), then the second logic platform door... Figure 5 As shown, Figure 5 PSD2-4 in the diagram refers to a set of second logic platform doors. For example... Figure 2 The smallest unit shown includes four trains, each with five doors. Therefore, a set of the smallest units includes 4 × 5 = 20 doors. Figure 2 The two smallest train units operate in mechanical formation, therefore all train doors are valid. At this time, the second logic platform door is as follows: Figure 6 As shown, Figure 6 PSD2-1 and PSD2-2 are both sets of second logic platform doors. PSD2-1 and PSD2-2 correspond to respectively Figure 2 The two smallest groups of units in the middle. For example... Figure 3 The smallest unit shown includes four trains, each with five doors. Therefore, a set of the smallest units includes 4 × 5 = 20 doors. Figure 3The two smallest group units are virtually grouped and operated, therefore all train doors of the lead car are valid train doors, and all train doors of the following cars except the last one are valid train doors. At this time, if the left side is the lead car and the right side is the second logical platform door in the direction of travel of the following car, such as... Figure 7 As shown, Figure 7 PSD2-1 and PSD2-3 are both a set of second logic platform doors. PSD2-1 corresponds to the smallest group unit of the leading car, and PSD2-2 corresponds to the smallest group unit of the following car.
[0059] It should be noted that the second logical platform door is the platform door for actual boarding and alighting; therefore, it corresponds one-to-one with only the valid train doors that actually participate in boarding and alighting when the smallest train unit stops. If all train doors are valid train doors, then the first and second logical platform doors may appear to be the same, only named differently due to different grouping reasons. Figure 7 PSD2-1 and Figure 4 The PSD1-1 in the code actually includes the same platform doors; if there are invalid train doors, then the first logical platform door and the second logical platform door will be different, that is... Figure 7 PSD2-2 and Figure 4 The platform doors included in PSD1-2 are not the same.
[0060] As explained above, each platform includes at least one set of first logical platform screen doors, wherein each first logical platform screen door comprises multiple consecutive platform screen doors, and the platform screen doors in each set of first logical platform screen doors do not overlap. Each first logical platform screen door uniquely corresponds to a smallest group unit, and the number of platform screen doors in the first logical platform screen door is the total number of train doors of all trains included in its corresponding smallest group unit.
[0061] After grouping the platform screen doors as described above, control can be applied to the second logic platform screen doors in each group. In other words, all doors included in each group of second logic platform screen doors can be controlled uniformly. This ensures fine control of the platform screen doors (the control granularity matches the smallest group unit) and reduces the number of control commands (e.g., unifying 20 control commands for platform screen doors into 1 control command for the second logic platform screen door), thus achieving precise and efficient refined control of the platform screen doors.
[0062] The above control process can be implemented in either of the two methods or both, and the appropriate control method can be selected based on specific requirements and environmental constraints.
[0063] The first control method is based on a safety redundancy network channel. In this method, a new network interface is added between the signaling system (CI) and the platform screen door system to enable the issuance of opening and closing commands for different smallest group units and their corresponding second logical platform screen doors. For example, the addition of a safety redundancy network channel between the signaling system (CI) and the platform screen door system enables platform screen door control for different train formation types and parking positions. This includes adding network platform screen door control commands such as adding 8-train opening / closing, and opening / closing the first 4A trains (corresponding to the lead car in two smallest group unit mechanical or virtual train formation situations, such as...). Figure 2 or Figure 3 The lead car, Figure 6 or Figure 7 PSD2-1), rear 4A door opening / closing (corresponding to the following car with the two smallest mechanical grouping units, such as...) Figure 2 The following car, Figure 6 PSD2-2), virtual rear 4A door opening / closing (corresponding to the following car in the virtual grouping situation of the two smallest group units, such as...) Figure 3 The following car, Figure 7 (PSD 2-3).
[0064] For the first control method, after receiving the control command, the platform screen door system controls all platform screen doors in the second logical platform screen door corresponding to the smallest group unit to open or close. Additionally, the platform screen doors use the first logical platform screen door as the smallest unit for collecting information on their closed and locked states. The closed and locked states of the first logical platform screen door are fed back through a newly added network interface between the signaling system (CI) and the platform screen door system. After obtaining the closed and locked states of each first logical platform screen door, the signaling system (CI) periodically reports them to the Zone Controller (ZC).
[0065] The first control method, when implemented, requires: 1) the platform screen door system to undergo SIL4 safety certification; 2) the platform screen door system to be connected to the signal security network, and network information security isolation is recommended; 3) connection to the signal security network requires the platform screen door to meet the Level 3 security protection requirements, necessitating the addition of a firewall. The first control method involves less indoor wiring, more complex software logic, and more flexible adjustments, but requires additional equipment, thus increasing equipment costs.
[0066] The second control method is based on a hard-wired connection channel. In this method, the signaling system (CI) and the platform screen door system establish a hard-wired connection channel through a hard-wired input / output (IO) interface, thereby enabling the issuance of opening and closing commands for different smallest group units and their corresponding second logic platform screen doors. For example, the signaling system (CI) and the platform screen door system establish a hard-wired connection channel through a hard-wired input / output (IO) interface to achieve platform screen door control for different train formation types and different parking positions. This includes adding platform screen door control IOs, such as adding 8-group door opening / closing and the first 4A door opening / closing (corresponding to the lead car in two smallest group unit mechanical or virtual train formation situations, such as...). Figure 2 or Figure 3 The lead car, Figure 6 or Figure 7 PSD2-1), rear 4A door opening / closing (corresponding to the following car with the two smallest mechanical grouping units, such as...) Figure 2 The following car, Figure 6 PSD2-2), virtual rear 4A door opening / closing (corresponding to the following car in the virtual grouping situation of the two smallest group units, such as...) Figure 3 The following car, Figure 7 (PSD 2-3).
[0067] For the second control method, the platform screen doors use the first logical platform screen door as the smallest unit for collecting the closed and locked status. Two additional I / O channels are added between the signaling system (CI) and the platform screen door system to feed back the closed and locked status of the first logical platform screen door. After obtaining the closed and locked status of each first logical platform screen door, the signaling system (CI) will periodically report it to the Zone Controller (ZC).
[0068] The second control method requires more hard wiring, more relays, and is inconvenient to maintain. It also requires additional I / O boxes. However, the technology is mature, the delay is fixed, and the software logic is simple.
[0069] Regardless of the control method used, the first logic platform door provides the closed and locked state, while the second logic platform door controls the opening and closing of the platform door.
[0070] Based on the above improvements, this embodiment provides a platform door control method for virtual train formation operation. In the implementation scenario, the virtual train formation includes at least one smallest group unit, where each smallest group unit includes at least one train. Each platform includes at least one set of first logical platform doors, where each first logical platform door includes multiple consecutive platform doors, and the platform doors in each set of first logical platform doors do not overlap. Each first logical platform door uniquely corresponds to one smallest group unit, and the number of platform doors in the first logical platform door is the total number of train doors of all trains included in its corresponding smallest group unit. Each platform includes at least one set of second logical platform doors, where the platform doors in each set of second logical platform doors do not overlap. Each second logical platform door uniquely corresponds to one smallest group unit, and the number of platform doors in the second logical platform door is the total number of valid train doors of all trains included in its corresponding smallest group unit. The valid train doors of a train are the train doors used for passenger boarding and alighting. Any platform door in any set of first logical platform doors may be the same as or different from any platform door in any set of second logical platform doors.
[0071] See Figure 8 The implementation process of the platform door control method for virtual group operation provided in this embodiment is as follows:
[0072] 801. The Vehicle On-Board Controller (VOBC) continuously determines the closed and locked status of each group of first logic platform doors at the target platform.
[0073] The target platform is either the platform where the train is about to stop or the platform where it is currently stopping. Therefore, the method provided in this embodiment can control the platform doors of a platform from the moment a train is about to enter the station until it has finished leaving the station.
[0074] In addition, if the train consists of multiple sets of the smallest unit, the onboard controller (VOBC) can be the onboard controller (VOBC) of the lead car.
[0075] As can be seen from the above description, the vehicle controller (VOBC) continuously obtains the status of the first logic platform doors of each group of target platforms being closed and locked from the area controller (ZC).
[0076] The closed and locked status of the first logic platform door in each group is periodically reported by the signaling system (CI) to the area controller (ZC).
[0077] A secure redundant network channel is established between the signaling system (CI) and the station door system. The signaling system (CI) obtains the closed and locked status of each group of first logic station doors through the secure redundant network channel.
[0078] And / or, a hardwired connection channel is established between the signaling system (CI) and the station door system via a hardwired input / output (IO) interface. The signaling system (CI) obtains the closed and locked status of each group of first logic station doors through the hardwired connection channel.
[0079] 802. If the closed and locked states of each group of logical platform doors are both closed and locked, and the virtual train has stopped accurately after entering the station, the on-board controller (VOBC) controls the opening and closing of the second logical platform door corresponding to each smallest group unit.
[0080] If the first control method is used, the process by which the on-board controller (VOBC) controls the opening and closing of the second logic platform door corresponding to each smallest group unit is as follows:
[0081] 1. The Vehicle Controller (VOBC) sends target control commands to the signaling system (CI) (i.e., the above-mentioned 8-group door opening / closing, front 4A door opening / closing, rear 4A door opening / closing, virtual rear 4A door opening / closing, etc.).
[0082] Among them, the target control command is used to control the opening or closing of the second logic platform door corresponding to each smallest group unit.
[0083] 2. The signaling system (CI) controls the station door system through a safety redundancy network channel based on the target control command, and opens or closes the corresponding second logic station door.
[0084] If the second control method is used, the process by which the on-board controller (VOBC) controls the opening and closing of the second logic platform door corresponding to each smallest group unit is as follows:
[0085] A. The Vehicle Controller (VOBC) sends target control commands to the Signal System (CI) (i.e., the aforementioned 8-unit door opening / closing, front 4A door opening / closing, rear 4A door opening / closing, virtual rear 4A door opening / closing, etc.).
[0086] Among them, the target control command is used to control the opening or closing of the second logic platform door corresponding to each smallest group unit.
[0087] B. The signaling system (CI) is based on target control commands and is connected to the channel control station door system via hardwire to open or close the corresponding second logic station door.
[0088] In addition, after the Vehicle Controller (VOBC) continuously determines the closed and locked status of each group of first logical platform doors of the target platform, if at least one group of first logical platform doors is not closed and locked, the Vehicle Controller (VOBC) controls the virtual train formation to stop.
[0089] In this embodiment, a platform screen door control method for virtual group operation is provided, through a first logical platform screen door (such as...) Figure 4 The PSD1-1 and PSD1-2 in the system provide a closed and locked state, which can be used for the closed and locked state of the platform doors corresponding to the smallest group unit (such as the first 4 virtual group and the last 4 virtual group). The door opening and closing command state is provided by the second logical platform door (such as... Figure 6 PSD2-1, PSD2-2, or Figure 7 The PSD2-1 and PSD2-3 in the document are accepted.
[0090] by Figure 3 Taking the virtual train formation shown as an example, the implementation process of the method provided in this embodiment will be explained again:
[0091] 1. The signaling system (CI) periodically reports the status of all platform screen doors being closed and locked to the zone controller (ZC). The status of all platform screen doors being closed and locked is determined by... Figure 6 The closed and locked states of PSD1-1 and PSD1-2 are shown. The closed and locked states of PSD1-1 and PSD1-2 are obtained by the signaling system (CI) through a secure redundant network channel, and / or by the signaling system (CI) through a hard-wired connection channel.
[0092] 2. The Zone Controller (ZC) sends the closed and locked status of PSD1-1 and the closed and locked status of PSD1-2 to the virtual train formation.
[0093] 3. When at least one of the closed and locked states of PSD1-1 and PSD1-2 is not closed and locked (e.g., the door is open), the virtual train formation is not allowed to enter the station and should stop immediately in front of the station or stop in the station by emergency braking. That is, the onboard controller (VOBC) controls the virtual train formation to stop.
[0094] 4. When neither the closed and locked state of PSD1-1 nor the closed and locked state of PSD1-2 is not closed and locked (i.e., the closed and locked state of each group of logical platform doors is closed and locked), after the virtual train enters the station and stops accurately, the on-board controller (VOBC) of the lead car sends the door opening and closing commands of PSD2-1 and PSD2-3 to the signaling system (CI).
[0095] 5. After receiving the door opening / closing command, the signaling system (CI) controls the station door system through the safety redundancy network channel, and / or drives the platform doors except for door No. 21 to open and close through the hard-wired connection channel to control the station door system.
[0096] 6. During the virtual train's platform operation and departure process, the closed and locked status of PSD1-1 and PSD1-2 are continuously checked. If at least one of the closed and locked statuses of PSD1-1 and PSD1-2 is not closed and locked (such as when a door is open), the virtual train will immediately apply emergency braking to stop, that is, the onboard controller (VOBC) will control the virtual train to stop.
