Abstract

Embodiments of the present disclosure provide methods, devices, and computer-readable storage media for remotely screening upgraded trains. The method comprises the steps that a zone controller ZC sends a train awakening permission list to a TIAS so that the TIAS sends a remote awakening instruction to a VOBC (video object controller) of a dormant train; the ZC receives a static test request sent by the VOBC after receiving the remote wake-up instruction, and sends a screenable train list to the TIAS for applying for remote screening of the dormant train; and after receiving the remote screening confirmation information, the ZC sends a static test permission instruction to the VOBC. The method can screen and upgrade the train in situ to a CBTC mode by remotely and rapidly screening and upgrading the train under the condition of no motor train (namely, the train does not carry out the operation of leaving the warehouse and returning the warehouse), and can rapidly upgrade the train to a FAM mode by human-computer interaction for full-automatic leaving the warehouse; the fault recovery time of the system is shortened, the availability of the system is improved, and the labor cost is reduced.

Description

Method for remotely screening and upgrading train

Technical Field

Embodiments of the present disclosure relate generally to the field of rail transit technology, and more particularly, to a method, apparatus, and computer-readable storage medium for remote screening of upgraded trains in a rail transit fully-automatic operation system.

Background

With the development of science and technology, the requirements of full-automatic operation and high efficiency are more and more urgent. As a mainstream technology for selection of each urban rail transit, a Train Control system Based on CBTC (Communication Based Train Control) provides a possibility for improvement of urban rail transit transportation capability on the premise of ensuring high safety, high reliability and high availability.

For the rail transit industry, in order to improve the automation level of trains and save the labor and time cost, a full-automatic operation system becomes the main development direction of a train control system. The full-automatic operation system is a full-automatic train operation control system with highly centralized control, has the functions of automatic train awakening start and dormancy, automatic access to a parking lot, automatic cleaning, automatic driving, automatic parking, automatic door opening/closing and the like, and has multiple operation modes of conventional operation, degraded operation, disaster working conditions and the like. Compared with the conventional CBTC system, the system has higher requirements on automation degree and reliability, can more accurately control the train according to the optimal mode, improves the operation efficiency and the operation service quality, and reduces the operation and maintenance cost.

In the existing CBTC system, after a Zone Controller (ZC) crashes or is restarted due to a cause, trains in its jurisdiction area need to be degraded to RM (Restricted train operation Mode) manually operated trains, and the trains need to work in cooperation with a vehicle-mounted response interrogator through a transponder arranged on a line, and are relocated, screened and upgraded to ensure that there are no engineering vehicles or other obstacles behind the front of the trains.

In the full-Automatic operation system, a full-Automatic dormancy awakening Train detection library is arranged, for a dormant Train in the library, a central ATS (Automatic Train Supervision) module needs to check a Train dormancy awakening state reported by a vehicle-mounted dormancy awakening module and a dormancy awakening state reported by a ZC (zero crossing zone) module, and when both reports that awakening is allowed, the ATS allows an awakening instruction to be issued to the Train; when the dormant trains in the train inspection warehouse are crashed or restarted due to reasons, the ATS cannot acquire a dormant awakening state from the ZC, all the dormant trains cannot be automatically awakened, and people need to be dispatched to get on the train to awaken the train through manual operation.

In the existing line design scheme of in-situ positioning automatic screening and upgrading, dormancy awakening transponders are laid at two ends of a train head and a train tail of a full-automatic dormancy awakening train inspection library, and as long as a train stops accurately at a parking point and the train is awakened manually, a Vehicle-mounted VOBC (Vehicle On-Board Controller) can directly obtain the position of the dormancy awakening transponder from a BTM antenna for direct positioning. After the positioned train is communicated with the ground ZC, the ZC can screen the train according to the position of the train, and the vehicle can be upgraded to a CBTC mode in situ as long as the line condition is met. The full-automatic dormancy awakening column inspection library is divided into a single column inspection library and a double column inspection library and is designed as follows;

1) design of single-row library as shown in figure 1 of the accompanying drawings

a) The parking train check line is arranged with the center of the dormancy awakening transponder and the center of the vehicle-mounted BTM (Transponder Module) antenna in alignment, and is used for awakening the train in dormancy and ensuring the automatic positioning of the awakened train.

b) The design of the stopping point ensures that the position of the axle counting point at the front distance of the train head is less than the minimum length of the whole line.

The arrangement mode of the line enables the ZC to be capable of obtaining the position of the train after being restarted after being crashed, and the vacant front section of the train and the hidden train in the front and the rear of the section where the ZC is located are checked according to the position information, so that the train is judged to meet the screening and upgrading conditions, and effective MA (Movement Authority) is calculated for the train, and therefore the train can be automatically upgraded into a CBTC mode in situ.

2) Double row library design (with C track), as shown in FIG. 2 of the accompanying drawings

a) The center of the dormancy awakening transponder arranged on the parking train check line and the center of the vehicle-mounted BTM antenna are arranged in an alignment mode and used for awakening the train in a dormancy mode, and meanwhile automatic positioning after the train is awakened can be guaranteed.

The arrangement mode of the circuit enables the ZC to be capable of obtaining the position of the train after the halt is restarted, and the front and rear sections of the train are free and no hidden train is arranged in the front and rear of the section where the ZC is located according to the position information, so that the train is judged to meet the screening and upgrading conditions, effective MA is calculated for the train, and the train can be automatically upgraded into a CBTC mode in situ.

However, the existing line design scheme for in-situ positioning automatic screening and upgrading has the defects that:

when the ZC equipment is down or restarted, the train is degraded, the ZC cannot report and allow a train list to be awakened, the ATS cannot remotely power on the train, and the train must be manually powered on, so that the labor cost and the management cost are increased;

in addition, due to the limited delivery capacity of the train section train inspection warehouse, only at most two trains (such as a double-train inspection warehouse design) can be delivered and upgraded at the same time, and the train inspection warehouse can stop 20 or 30 or more trains, and the trains need to be delivered and returned to the warehouse to complete the upgrade of the FAM mode (full-automatic driving mode). This increases the failover time of the system, reducing the availability of the system.

In the field debugging stage of the system, when the ZC equipment needs to upgrade the version, the on-site debugging time is long and the on-site manpower is matched for upgrading, so that the engineering application cost is increased.

Meanwhile, the existing line design scheme for in-situ positioning automatic screening and upgrading is only suitable for lines of fixed marshalling trains, and has higher requirements on civil engineering line design; and the rail transit line has the situation that 4 groups, 6 groups and 8 groups run together, and also has the situation that 4 groups are reserved for 6 groups or 8 groups for operation in the early period of operation, and the line design is complicated and changeable and has no universality.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

FIG. 3 illustrates a schematic diagram of an exemplary operating environment 300 in which embodiments of the present disclosure can be implemented. The operation environment 300 comprises an on-board controller VOBC302, a zone controller ZC304 and a running integrated control automation system TIAS 306; although only one VOBC302 is shown in fig. 3, a plurality of VOBCs 302 can be included in the runtime environment 300.

In this embodiment, when the parking train inspection library line does not satisfy the line design of the existing in-situ positioning autofilter upgrade, or there is mixed operation of long and short marshalling, and the conditions of autofilter upgrade in the line design scheme of the existing in-situ positioning autofilter upgrade cannot be satisfied, the autofilter upgrade cannot be completed after the train is awakened.

For example, as shown in fig. 4, the position of the stopping point from the train head to the front axle counting point is larger than the full-line minimum length (in the figure, the full-line minimum length is 25 m). When the distance between the stop point and the train inspection warehouse axle counting point is larger than the full-line minimum train length (25m), the trolley can be hidden, and even if the middle C rail section of the train inspection warehouse is idle, the train can not finish automatic screening.

According to the embodiment of the disclosure, by means of a remote screening and upgrading method of manually confirming that no engineering vehicle or other obstacles in the train inspection warehouse in batch without getting on the train and manually confirming the train by the center for the second time, less manpower is input into the unmanned garage, and the train is remotely controlled to be upgraded by the center.

In the route arrangement shown in fig. 5, the B1 and B2 libraries can both store a train of sleeping cars or degrading cars, and in this scenario, the train is in an RM mode; if the method for upgrading the train by local manual screening is adopted, the train can only be upgraded to be delivered out of the train at the CBTC level, but the train can not be subjected to dormancy awakening and full-automatic delivery, namely VOBC can be upgraded to be delivered out of the train from the RM mode, but the condition of upgrading to the FAM mode is not met because the tail end screening condition is not met. At the moment, the driver can manually drive the train to get out of the garage in a CBTC-CM or CBTC-AM mode, and the conditions of dormancy awakening again and full-automatic getting out of the garage are not met.

Fig. 6 shows a flowchart of a method 600 of remotely screening an upgraded train according to a first embodiment of the present disclosure; the method 600 may be performed by the zone controller ZC304 of figure 3; the method comprises the following steps:

In the context of this disclosure, a machine-readable medium may be a tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. The machine-readable medium may be a machine-readable signal medium or a machine-readable storage medium. A machine-readable medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

Further, while operations are depicted in a particular order, this should be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. Under certain circumstances, multitasking and parallel processing may be advantageous. Likewise, while several specific implementation details are included in the above discussion, these should not be construed as limitations on the scope of the disclosure. Certain features that are described in the context of separate embodiments can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination.

Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.

Claims

1. A method for remotely screening an upgraded train is characterized by comprising the following steps:

a zone controller ZC sends a train awakening permission list to a traffic integrated control automation system TIAS; the train awakening permission list comprises train identifications and dormancy awakening states of dormant trains;

the TIAS receives a list of trains allowed to be wakened and sent by the ZC, and sends a remote wakening instruction to a VOBC (vehicle-mounted controller) of the dormant train;

the VOBC receives the remote awakening instruction and sends a static test request to the ZC;

the ZC receives the static test request, sends a screenable train list to the TIAS and applies for remote screening of the dormant train;

the TIAS receives the screenable train list, and sends confirmation information to the ZC after manually confirming that the dormant train has the remote screening condition; the step of manually confirming that the dormant train has the remote screening condition comprises the step of popping up a prompt to a dispatcher by the TIAS, and prompting the ZC to apply for remote screening of the dormant train; the dispatching personnel inform field personnel to check the garage condition according to the prompt; after field personnel check the condition of the garage in batches, reporting to dispatching personnel that no obstacle exists in front and at the back of the train; the dispatching personnel performs twice screening confirmation, selects trains in batches and confirms whether the dormant trains have remote screening conditions;

and the ZC receives the confirmation information and sends a static test permission instruction to the VOBC so that the VOBC of the dormant train controls the dormant train to carry out static test.

2. The method of claim 1, wherein the TIAS receives the list of wakening allowed trains sent by the ZC, and sending a remote wakening instruction to a VOBC on-board the dormant train comprises:

and when the dormancy awakening states of the dormant train sent by the ZC and the VOBC are both allowed to be awakened, the TIAS sends a remote awakening instruction to the VOBC of the dormant train.

3. The method of claim 1, wherein the VOBC receives the remote wake-up instruction, and wherein sending a static test request to the ZC comprises:

and the VOBC receives the remote awakening instruction, performs power-on self-check on the dormant train, and sends a static test request to the ZC after the self-check is passed.

4. The method of claim 1, wherein the remote screening condition is:

and screening and confirming the front and rear sides of the dormant train without obstacles, wherein the front and rear trains cannot move.

5. The method of claim 1, further comprising:

and reporting the success of screening the dormant train to the TIAS by the ZC while/before/after sending a static test permission instruction to the VOBC.

6. The method of claim 1, further comprising:

the ZC receives a dynamic test request sent by the VOBC after completing the static test; and determining whether the test environment of the train meets dynamic test conditions, and if so, sending a dynamic test permission instruction to the VOBC to enable the VOBC to perform dynamic test.

7. An electronic device comprising a memory and a processor, the memory having stored thereon a computer program, wherein the processor, when executing the program, implements the method of any of claims 1-6.

8. A computer-readable storage medium, on which a computer program is stored, which program, when being executed by a processor, carries out the method of any one of claims 1 to 6.
