Description
Technical Field
The application relates to the field of rail transit, in particular to a virtual marshalling train operation control method and system.
Background
With the rapid development of science and technology, rail transit develops rapidly. The rail transit has the characteristics of convenience, quickness and the like, so that the rail transit becomes a travel choice for a plurality of passengers. Thus, the operation pressure of rail transit is also becoming more severe. In order to relieve the operation pressure, an operation mode using a virtual grouping technology to improve the operation efficiency is proposed, and the operation interval can be greatly shortened.
The virtual marshalling technology is that the rear train acquires the running state of the front train to control the running of the rear train through direct wireless communication between the trains, so that the multi-train coordinated running mode at the same speed and at extremely small intervals is realized through wireless communication. In this way, the trains which keep synchronous operation at a certain distance can be regarded as being linked, and compared with the traditional way, the traditional physical train hook linkage is changed into wireless communication linkage. The virtual marshalling mode has the characteristics of short operation time and large adjustment space, can greatly improve the line passing capacity and reduce the driving interval, so that the passenger flow adaptability is better, and the vehicle bottom application is more flexible.

However, in the actual operation process, the judgment on the zone occupation state is often too comprehensive, the factors on which the judgment is based are also limited, and a certain deviation is likely to exist between the judgment and the actual zone occupation state result. In addition, for the specific control of the interlocking system in the virtual marshalling train interval operation process, especially for the aspect of acquiring the zone occupation state, the existing interlocking system cannot meet the actual application scene, and no corresponding solution is provided.

Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example 1
As shown in fig. 1, the present embodiment provides a virtual marshalling train operation control method, including:
s101, the axle counting system sends the track section state of the target section to the interlocking CI.
The axle counting system comprises an axle counting sensor, which may be arranged at an end point of the track section. The axle counting system can determine whether the track section is in an occupied state or an idle state by comparing the number of axles recorded when the train enters or leaves the position of the track section axle counting sensor.
S102, the zone controller ZC sends the zone CT/UT state of the target zone and the zone formation state of the zone between the tracking distances of the front train and the rear train of the virtual formation train in the target zone to the interlocking CI.
The zone controller ZC can calculate and obtain the CT/UT state of the target zone according to the logical position of the train and before the maximum safety and after the minimum safety. Wherein, CT occupation indicates that only CBTC trains occupy in the target section, and UT occupation indicates that non-communication vehicles occupy in the target section. Therefore, in this embodiment, when a CBTC train or a non-communication vehicle exists in the target zone, the CT/UT status of the zone is an occupied status, otherwise, the CT/UT status of the zone is an idle status.
The virtual marshalling train at least comprises two trains, in this embodiment, two train marshalling are taken as an example and are respectively a front train and a rear train, and the front train is usually taken as a main control train of the virtual marshalling train. The leading car may communicate with the trailing car to obtain location information of the virtual consist to determine a tracking distance between the leading car and the trailing car of the virtual consist. In this embodiment, the section formation state refers to a state of a section between tracking distances of a front car and a rear car of a virtual formation train. The zone consist state is an occupied state for a virtual consist, and an idle state for a non-virtual consist.
S103, the interlocking CI fuses the track section state, the section CT/UT state and the section grouping state to obtain a station track section state of the target section.
The track segment states and segment CT/UT states are more conventional types of segment occupancy states. Since the tracking distance exists between the front car and the rear car of the virtual train set, the zone train set state is an occupancy type specific to the virtual train set. Due to the existence of the special section grouping state, the section fusion logic of the target section is bound to have an influence. Therefore, the present embodiment proposes a sector fusion logic for the sector grouping status, that is, fusion processing is performed on the track sector status, the sector CT/UT status, and the sector grouping status to obtain the track sector status of the target sector, as shown in table 1:
TABLE 1
| Serial number | Track segment status | Sector CT/UT states | Segment marshalling status | Track segment status |
| 1 | 0 | 0 | 0 | 0 |
| 2 | 0 | 0 | 1 | 1 |
| 3 | 0 | 1 | 0 | 0 |
| 4 | 0 | 1 | 1 | 1 |
| 5 | 1 | 0 | 0 | 0 |
| 6 | 1 | 0 | 1 | 1 |
| 7 | 1 | 1 | 0 | 1 |
| 8 | 1 | 1 | 1 | 1 |
In table 1, "0" indicates an idle state, and "1" indicates an occupied state. When the track section state and the section CT/UT state are simultaneously in an occupied state or the section grouping state is in an occupied state, the track section state is in an occupied state. In other cases, the track segment status is idle. In the embodiment, the track section state, the section CT/UT state and the section marshalling state of the target section are fused to obtain the station track section state of the target section, so that the occupation state of the target section is more accurately obtained by analyzing the actual scene in the running process of the virtual marshalling train. When the station track section state is the occupied state, the front vehicle and the rear vehicle can be determined to be in a real connection state in the process of passing through the target section. Therefore, the interlocking CI can integrate the front train and the rear train, so that the front train and the rear train can smoothly enter a target section, and ensure that no other trains are inserted between the two trains, thereby ensuring the normal operation of the virtual marshalling train.
And S104, the interlocking CI performs access handling on the virtual marshalling train according to the station track section state.
After the station track section state is obtained, if the station track section state is an occupied state, the interlocking CI can conduct route handling for the virtual marshalling train so that the virtual train can drive into the target section.
Specifically, when the route signal machine of the target section is located within the tracking distance between the front train and the rear train in the process that the virtual marshalling train drives into the target section, the interlock CI controls the route signal machine to be in an open state, at the moment, the route is locked, and the rear train can normally drive into the target section. When the safety positions of the whole front train and the safe front position of the rear train of the virtual marshalling train pass through the access signal machine of the target section, the zone controller ZC sends a cross-voltage mark to the interlocking CI. The interlock CI can think that the front train and the rear train of the virtual marshalling train smoothly pass through the access signal machine and drive into the target section according to the cross-pressure mark, and at the moment, the interlock CI closes the access signal machine and triggers the access unlocking. During this time, the section grouping status of the section between the tracking distances of the leading and trailing cars is always maintained in the occupied state. According to the section fusion logic proposed in the embodiment, the station track section state is also an occupied state, i.e. it can be ensured that the virtual marshalling train enters the target section. By the method, the rear train can be ensured to run along with the front train, the whole regulation and control of the rail train are facilitated, and the normal running of the virtual marshalling train is further ensured.
The track section state of the target section is sent to the interlocking CI through the axle counting system; the zone controller ZC sends the zone CT/UT state of the target zone and the zone marshalling state of the zones between the tracking distances of the front train and the rear train of the virtual marshalling train in the target zone to the interlocking CI; the interlocking CI carries out fusion processing on the track section state, the section CT/UT state and the section grouping state to obtain a station track section state of a target section; and the interlocking CI performs access handling for the virtual marshalling train according to the station track section state. In this embodiment, the track section state, the section CT/UT state, and the section marshalling state of the target section are fused to obtain the station track section state of the target section, so as to more accurately obtain the occupation state of the target section by analyzing the actual scene of the virtual marshalling train in the operation process, so that the interlock CI can control the operation of the virtual marshalling train according to the actual operation scene of the virtual marshalling train, thereby ensuring the normal operation of the virtual marshalling train.
The above process can ensure that the virtual marshalling train safely enters the target section by obtaining the station track section state of the target section.
In some embodiments, the virtual marshalling train may be decompiled during operation, for example, when the front train is degraded from CBTC to UT, the virtual marshalling train may be decompiled forcibly. At this time, if the tracking interval between the front vehicle and the rear vehicle is smaller than one axle counting section, even if the front vehicle and the rear vehicle are forcibly unscrambled, the front vehicle and the rear vehicle are still a whole body and occupy the same section without any influence for the interlock IC. When the tracking interval between the front vehicle and the rear vehicle is larger than one axle counting section, namely the front vehicle and the rear vehicle cross the section, once the virtual marshalling train is forcedly un-marshalled, the section marshalling state of the section between the tracking intervals of the front vehicle and the rear vehicle is changed into an idle state. The interlock CI controls the start semaphore to close and triggers the route unlocking when the preceding vehicle passes the start semaphore of the target segment. At this time, the rear vehicle may rush over the start signal of the target section to break into the unlocked section, which causes a great potential safety hazard. Therefore, in this embodiment, when the tracking interval between the leading car and the trailing car is greater than one axle counting zone for the codec, the zone controller ZC acquires codec information transmitted when the virtual marshalling train operates in the zone, and then transmits the state information that the zone marshalling state is the idle state to the interlock CI according to the codec information. Fig. 2 is a schematic diagram illustrating transition among a zone consist state, a zone CT/UT state, and an idle state when the virtual consist train is de-consist during operation. After the interlocking CI obtains the state information, a 'delay free' processing mode is adopted, namely the interlocking CI still keeps the section grouping state to be an occupied state within the preset time, the access unlocking cannot be triggered, and the access locking of the target section is kept, so that a rear vehicle cannot break into the unlocked section. This means that the track section status and the section CT/UT status in the target section are both in the occupied status, and even if the section grouping status is actually in the free status, the track section status is set to the occupied status. In this embodiment, the preset time may be set according to the running speed of the virtual marshalling train, and may be the maximum time for the unlocking of the access train to stop when the train runs at the highest speed, so as to ensure the driving safety of the rear train after the virtual track train is unmarshaled. When a rear vehicle drives into a target section with a locked access within preset time, a zone controller ZC sends state information that the CT/UT state of the section is an occupied state to an interlocking CI (coordinated logic) to ensure that the interlocking CI updates the station track section state of the target section and the overall operation of a track system.
Due to the particularity of the virtual marshalling train in the coupling and running modes, the interlocking CI is required to be capable of respectively controlling the shielding doors of the front train and the rear train of the virtual marshalling train. In this embodiment, the vehicle-mounted controller VOBC of the front vehicle and the vehicle-mounted controller VOBC of the rear vehicle may respectively send the door opening codes of the shield doors of the front vehicle and the rear vehicle to the interlock CI, so that the interlock CI may control the opening and closing states of the shield doors of the front vehicle and the rear vehicle according to the received door opening codes.
More specifically, the interlock CI may control the open and closed states of the shield door using a relay. For example, two door opening relays 4AKMJ and 4BKMJ and one 8AKMJ may be provided in this embodiment to respectively control the barrier door controller corresponding to each 4 marshalling trains and the barrier door controller corresponding to 8 marshalling trains, so as to control the opening state of the barrier door. And two door closing relays of 4AGMJ and 4BGMJ and an 8AGMJ door closing relay can be further arranged to respectively control the shield door controller corresponding to each 4 marshalling trains and the shield door controller corresponding to 8 marshalling trains so as to control the closing state of the shield door. Two gate-closing relays of 4AMGJ and 4BMGJ and an 8AMGJ gate-closing relay can be arranged, and the shield gate switching state corresponding to each 4 marshalling trains and the shield gate switching state corresponding to 8 marshalling trains are respectively corresponding to the two gate-closing relays. In this way, the interlock CI communicates with the front and rear vehicles simultaneously to ensure that the onboard controllers VOBCs on the front and rear vehicles can send the door opening code to the interlock CI. The interlocking CI drives different shielding door combinations according to different received door opening codes, such as a front vehicle drive 4AGMJ and a rear vehicle drive 4 BGMJ. For the shielding door switch state, the corresponding shielding door switch states can be respectively collected according to two door switch relays of 4AMGJ and 4BMGJ and then reported to the VOBC of the front vehicle and the rear vehicle. No matter the virtual marshalling train runs in the virtual coupling period or the front train and the rear train run respectively after the virtual marshalling train is decompiled, the interlocking CI can be switched to the corresponding control logic to control the opening and closing state of the shielding door, the opening and closing function of the shielding door cannot be influenced due to the change of the running mode of the train, and therefore the train can be guaranteed to pass in and out smoothly by passengers in the train or a platform.
Further, as shown in fig. 3, in this embodiment, before the virtual marshalling train performs the interval operation, the virtual marshalling process needs to be completed first, and the specific process is as follows:
s201, a train automatic monitoring system ATS indicates a front train to drive into a specified coupling area and receives information to be coupled sent by the front train;
s202, after receiving information to be linked sent by a front train, an automatic train monitoring system ATS sends a linked approach handling instruction to an interlocking CI;
s203, the interlock CI transacts a linked route for the rear vehicle according to the linked route transacting instruction;
and S204, the automatic train monitoring system ATS indicates that the rear train enters the coupling area to enter a coupling process after the interlocking CI successfully transacts the coupling route, and forms a virtual marshalling train with the front train.
Specifically, in this embodiment, the designated linking area may be located in the train section inspection warehouse, the pulling line, the main line returning line, the parking line or the platform, and this embodiment is not particularly limited. And after the automatic train monitoring system ATS indicates that the front train drives into the designated coupling area, the front train executes self coupling preparation work. After the preparation work is ready, the information to be linked can be fed back to the automatic train monitoring system through a manual mode or a VOBC (vehicle-mounted controller) of the front train so as to indicate that the front train is ready. At the moment, the automatic train monitoring system ATS sends a linkage access handling instruction to the interlock CI, and handles a linkage access for the rear train through the interlock CI, so that the rear train drives into a linkage area to be virtually linked with the front train to form a virtual marshalling train. Besides being sent by the automatic train monitoring system ATS, the linked approach handling instruction can also be sent to the interlocking CI in a manual triggering mode. In the embodiment, the virtual linkage scene is analyzed, and the interlocking CI is controlled to realize the movement of the front vehicle and the rear vehicle between the linkage areas, so that the smooth execution of the linkage is ensured.
In this embodiment, after the preceding vehicle enters the designated hitching area, the information to be hitched sent by the zone controller ZC is sent to the interlock CI after the hitching area is marked as the occupied state according to the information to be hitched, so as to ensure that no other vehicle enters the area during the subsequent hitching of the preceding vehicle and the following vehicle, and further ensure the successful execution of hitching.
The designated hitching area can be in different scenes, and for simple line scenes such as an online line, the CBTC-level route can be successfully handled without other processing. However, for a complex route scene such as a vehicle section, due to the fact that a CBTC-level route does not exist, it is required to ensure that a designated link area is in an occupied state, and when a start-end signal of the link area is in a light-off state, the interlock CI will handle the link route for a rear vehicle, so that a link operation in the complex route scene is solved, and the link safety is improved.
Although the coupling between the front vehicle and the rear vehicle is a virtual coupling in this embodiment, there is still a risk of collision between the front vehicle and the rear vehicle during the actual coupling, and therefore collision protection during the coupling is also necessary. In this embodiment, after the train automatic monitoring system ATS indicates that the rear train enters the hitching zone, the zone controller ZC sends a protection zone request to the interlock CI. The interlock CI locks the front section of the linkage area according to the request of the protection section and feeds back locking information to a zone controller ZC. And after receiving the locking information, the zone controller ZC acquires the movement authorization of the rear car according to the position information of the front car and the rear car in the coupling zone and the length information of the coupling zone. And controlling the rear vehicle to move in the coupling area according to the movement authorization of the rear vehicle. The obtaining of the movement authorization can ensure that the front vehicle and the rear vehicle cannot cause collision during the coupling period to a certain extent, and meanwhile, even if the front vehicle and the rear vehicle collide with each other at a small probability, the movement distance of the front vehicle after collision can be prevented from being larger than the space allowance of the interlocking region, namely the movement distance cannot exceed the range of the interlocking region.
