Description

Method and system for locally and manually screening and upgrading trains

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 local manual 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 command 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, and is used for awakening the train in dormancy and ensuring the automatic positioning of the train after awakening.

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. A VOBC302 and a ZC304 are 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.

Fig. 5 shows a flowchart of a method 500 of local manual screening of upgraded CBTC trains, according to a first embodiment of the present disclosure; the method 500 comprises the steps of:

at block 505, the onboard controller VOBC reports the CBTC train location to the zone controller ZC and applies for a movement authorization MA;

at block 510, the ZC checks the train mode and the occupancy of the front and rear sections, and sends a corresponding screening flag to the VOBC according to the check result;

at block 515, the VOBC checks whether the train meets the corresponding sleep wake-up location condition according to the corresponding screening flag, and if so, prompts the driver to perform obstacle check through a man-machine interface MMI;

at block 520, the VOBC receives the confirmation message sent by the driver through the MMI, and replies a front-end and back-end screening permission mark to the ZC;

at block 525, the ZC sending the MA to the VOBC according to the allowed front and back end filter flags;

at block 530, the VOBC prompts the driver to upgrade based on the mobile authorization; and upgrading to an FAM mode according to the upgrading operation of the driver.

In an embodiment two of the present disclosure, the train is in a CBTC mode; the idle condition of the front and rear sections of the train is that the rear section is idle and the front section is occupied, and the train wakes up the train inspection warehouse in a sleeping state; meeting the preset condition of the train position (1) that a section in front of the train is idle; (2) the front part of the train is provided with a positioning section and a reverse section of the turnout section which are all idle; (3) a section behind the train is free or the rear section is a line end; (4) and (3) the train wakes up (3) - (4) in the parking garage line (comprising the positive line parking line, the storeroom A and the storeroom B) in the sleeping mode.

FIG. 6 shows a flow chart of a method 600 of local manual screening of upgraded trains in accordance with a second embodiment of the present disclosure; the method 600 comprises the steps of:

at block 605, after the VOBC power on self-test is passed, the current position of the train in the process of waking up the train is obtained through the dormancy wakeup transponder, and the train position is reported to the ZC.

In some embodiments, the train is awakened locally by manual boarding; the driver gets on the bus in advance according to the operation rule, opens the driver's cabin apron and the manual work presses awakening button. And carrying out equipment self-check after the VOBC is electrified.

At block 610, the ZC checks a train mode and occupancy of front and rear zones, and if the train mode is a CBTC mode and the occupancy of the front and rear zones of the train meets the preset train position condition (1) that the front zone of the train is idle; (2) the front part of the train is provided with a positioning section and a reverse section of the turnout section which are all idle; (3) a section behind the train is free or the rear section is a line end; (4) and (3) to (4) of the train in the dormancy awakening parking garage line (comprising a main line parking line, a garage A and a garage B), wherein the ZC sends a 'back end screening application mark' to the VOBC, namely sends a back end screening request to the VOBC to apply for back end screening. The occupation idle conditions of the front and the rear of the train in the CBTC mode meet (1) - (2) of the preset conditions of the train positions by default, namely the occupation idle conditions of the front and the rear sections of the train meet (1) - (4) of the preset conditions of the train positions.

At block 615, the VOBC receives the back-end screening request and checks whether the train meets a corresponding dormant wake-up location condition; if the detection result is satisfied, prompting a driver to carry out obstacle inspection through an MMI (Man Machine Interface).

Wherein the corresponding sleep wake-up location condition is: 1) the train is in a sleeping and awakening stop window; 2) zero speed; 3) the mode is CBTC-CM/CBTC-AM (non-FAM mode).

And if the corresponding dormancy awakening position condition is met, prompting a driver to check the barrier by the VOBC through an MMI (Man Machine Interface). For example, the driver is prompted to apply for "checking the presence or absence of an obstacle in front of or behind the train", and waits for the driver to press the confirmation button. Although the ZC determines that the front and rear sections of the train are free, there may be obstacles in front of and behind the section where the train is located, and in the front and rear sections of the train, for example, a train without installed or failed communication equipment, a false intrusion of an object, or other equipment suspended on a train track; therefore, manual inspection by a driver is required.

In some embodiments, if the driver checks that there is no obstacle in front of and behind the train, the driver presses the confirmation button twice (each button needs to last for 1s) according to the prompt. If the driver checks that no obstacle exists in the front and the rear of the train, after the confirmation button is pressed, the VOBC prompts the driver to check the obstacle again through the MMI, and the driver checks that no obstacle exists in the front and the rear of the train and presses the confirmation button again. Through the secondary confirmation, the safety is improved.

At block 620, the VOBC receives the confirmation message sent by the driver through the MMI; reporting + allowing front and back end screening marks to the ZC return position;

in some embodiments, the VOBC replies a front-end and back-end screening permission flag to the ZC after receiving the secondary confirmation message sent by the driver.

In some embodiments, the VOBC reduces communication with the ZC by adding a clear front-end and back-end screening flag to the location report returned by the ZC. In the embodiment of the disclosure, the VOBC and the ZC communicate normally, and send a local terminal 'train position information' packet to the ZC, and a 'front and back end screening permission flag' field is added to the packet.

At block 625, the ZC sends a valid MA (move Authority) to the VOBC according to the allowed front-end and back-end filter flags;

at block 630, the VOBC receives the MA and prompts the driver through the MMI for an upgrade.

In some embodiments, the VOBC performs corresponding driving control on the train according to the MA, for example, the VOBC is CBTC-CM/CBTC-AM, and the back-end screening is successful, and the VOBC has a condition of being upgraded to the FAM mode. The VOBC may prompt the driver to upgrade through the MMI. At the moment, a driver can reset the handle to zero according to the MMI prompt to close the key, the VOBC upgrades from the CBTC mode to the FAM mode according to the operation signal of the driver for resetting the handle to zero to close the key, and the VOBC has the conditions of dormancy awakening again and full-automatic warehouse-out.

According to the embodiment of the disclosure, the following technical effects are achieved:

the method for screening and upgrading the trains locally and manually is provided, and can screen and upgrade the trains locally and quickly by manual when the conditions of automatic screening and upgrading cannot be met after a ZC crashes or a fault restarts and a CBTC train is awakened, so that the trains can be screened and upgraded in situ under the condition that no trains are moved (namely, the trains do not go out of the warehouse and return to the warehouse), and can be upgraded to be automatically and automatically out of the warehouse in an FAM mode quickly by human-computer interaction; the fault recovery time of the system is shortened, the availability of the system is improved, and the labor cost is reduced.
