Description
Technical Field
The embodiment of the invention relates to the technical field of rail transit, in particular to a train operation control method and device.
Background
With the development of rail transit technology, urban rail transit plays an increasingly important role in public transportation industry. The urban rail transit has short train running time interval, high speed and less interference from other vehicles, can realize high-density running and has stronger transport capacity.
Currently, a Full Automatic Operation (FAO) train has become a development direction of urban rail transit in the future. The FAO train system is a highly centralized train operation system that fully automates the operations of train drivers.
In the operation process of a Communication Based Train automatic Control System (CBTC), reasons influencing safe operation include track factors, vehicle factors, power supply factors, signal System factors, human factors and the like; among the track factors, obstacles are the most harmful factor for train operation. Specifically, there may be obstacles on the train operation route that affect the normal operation of the train due to natural, artificial or accidental reasons, and if there are obstacles on the track, there is a high possibility of causing serious accidents such as collision and even derailment, resulting in significant loss. Therefore, when an obstacle appears on the track or the train collides with the obstacle, the processing mechanism should be started to avoid the train in the nearby area from being affected or other trains from entering the nearby area of the train.
However, in the current obstacle handling mechanism, the detection process is usually to install a detection device beside the track to monitor the line condition in real time; for the detection blind area which cannot be detected by the trackside equipment, after the detection blind area is generally found by a driver manually, relevant processing operation is carried out to ensure safety. However, in the FAO system, no driver participates in the running process of the train, and for the detection of the blind area, the existence of the obstacle on the line cannot be found in time, and the relevant processing operation cannot be performed in time. Therefore, the obstacle handling mechanism in the prior art has great limitation.

Fig. 1 is a schematic flow chart illustrating a train operation control method according to an embodiment of the present invention.
As shown in fig. 1, the train operation control method provided in the embodiment of the present invention is applied to a Zone Controller, where a Zone Controller (ZC) is a core component of a CBTC signal system and belongs to a part of a ground device. It divides a line into several control zones, usually each zone being responsible for one zone controller. Within the responsible zone, the ZC is responsible for providing the train with Movement Authorization (MA) telling the train the farthest distance to allow for advance.
The method specifically comprises the following steps:
The first train is provided with a sensor for detecting an obstacle, and optionally, the sensor can be installed at a preset position of the train head, such as a bogie; the sensor may be a contact sensor or a probe sensor; after the sensor detects the obstacle, the first train sends an obstacle signal to the ZC of the zone where the first train is located.
After receiving the obstacle signal, the ZC may have collided with the obstacle, and in order to avoid collision or other dangerous situations between the obstacle and another train in the vicinity of the first train, the ZC starts an obstacle processing mechanism, acquires current position information and a running direction of the first train, and performs a subsequent processing operation according to the position information and the running direction.
Optionally, the operating parameter is an operating parameter of the first train at a time when the obstacle signal is detected; the location information may be obtained from the train's on-board signal system, which determines the location information by obtaining on-board speed sensors, doppler radar in combination with absolute location beacons (passive beacons), which the train then transmits to ZC over a wireless network.
And the ZC determines a protection area according to the operation parameters, wherein the protection area comprises all possible operation paths of the train. Specifically, after the train collides with the obstacle, the train may continue to run on the current running route along the current running direction, for example, when the collision amplitude is small, the possible running path is a forward section along the current running direction at the current position information on the current route at this time; or when the collision amplitude is slightly larger, the train is rebounded after collision, namely, the train runs in the reverse direction of the current running direction, and the possible running path is a backward section of the current route; alternatively, when the collision amplitude is large, so that the first train is derailed, the possible travel path is a forward or backward section of the adjacent line.
Therefore, when the protection area is determined, all possible operation paths of the first train on the current line or the adjacent line are searched section by section according to the position information and the operation direction, and then the protection area is determined according to the possible operation paths.
And 103, sending an emergency braking instruction to the train located in the protection area and/or sending a movement authorization instruction excluding the protection area to the train located outside the protection area.
After the protection area is determined, an emergency braking instruction is sent to the train located in the protection area, and the train in the protection area is prevented from continuously running and colliding with the first train and the obstacle.
And/or sending a moving authorization instruction excluding the protection area to the train outside the protection area, so as to prevent the train outside the protection area from entering the protection area, wherein the Moving Authorization (MA) is the maximum distance for allowing the train to run under any condition. In general, when a ZC calculates an MA, it determines an operation authority of a train according to route information, line data, and temporary speed limit information provided by a Computer Interlocking (CI) system.
In the above embodiment of the present invention, after receiving an obstacle signal sent by a first train and used for indicating that the first train monitors an obstacle, a zone controller obtains an operation parameter of the first train; determining a protection area of the first train according to the operation parameters, sending an emergency braking instruction to the train located in the protection area and/or sending a movement authorization instruction excluding the protection area to the train located outside the protection area, and realizing automatic processing of an obstacle mechanism when an obstacle signal is received; the method does not depend on manual processing, and can be suitable for a detection blind area of an FAO system; and the possible running paths of the train on the current line and the adjacent line can be automatically searched, a protection area is established, the train in the protection area is prevented from being influenced, or other trains drive into the protection area of the train, and the influence of obstacles on the running of the track system is reduced. The embodiment of the invention solves the problem of limitation of an obstacle processing mechanism in urban rail transit in the prior art.
Fig. 2 is a schematic flow chart illustrating a train operation control method according to another embodiment of the present invention.
As shown in fig. 2, the train operation control method provided in the embodiment of the present invention is applied to a zone controller, and specifically includes the following steps:
the method specifically comprises the following steps:
The first train is provided with a sensor for detecting an obstacle, and optionally, the sensor can be installed at a preset position of the train head, such as a bogie; the sensor may be a contact sensor or a probe sensor; after the sensor detects the obstacle, the first train sends an obstacle signal to the ZC of the zone where the first train is located.
After receiving the obstacle signal, the ZC may have collided with the obstacle, and in order to avoid collision or other dangerous situations between the obstacle and another train in the vicinity of the first train, the ZC starts an obstacle processing mechanism, acquires current position information and a running direction of the first train, and performs a subsequent processing operation according to the position information and the running direction.
Alternatively, the location information may be obtained from the train's on-board signal system, which determines the location information by obtaining an on-board speed sensor, doppler radar in combination with absolute location beacons (passive beacons), which the train then transmits to the ZC over a wireless network.
If the position information indicates that the first train is not separated from the track currently, determining a current line according to the position information, and searching all adjacent lines in the ZC control area according to the current line;
if the first train is determined to be separated from the track currently according to the position information and the preset track information, the current route can be determined according to the original position information before the current moment, namely the original position information before the obstacle is detected by the first train, the train normally runs before the obstacle is detected, and the route corresponding to the original position information is the current route.
The possible operation path is all possible operation paths of the first train after the current time, specifically, after the train collides with the obstacle, the train may continue to operate on the current operation line along the current operation direction, for example, when the collision amplitude is small, the possible operation path is a forward section along the current operation direction at the current position information on the current line at this time; or when the collision amplitude is slightly larger, the train is rebounded after collision, namely, the train runs in the reverse direction of the current running direction, and the possible running path is a backward section of the current route; alternatively, when the collision amplitude is large, so that the first train is derailed, the possible travel path is a forward or backward section of the adjacent line.
And step 204, combining the possible running paths to form a protective area.
Setting the boundary of the maximum area where the possible travel paths are merged as the boundary of the obstacle protection area, and establishing the obstacle protection area by the boundary by the ZC.
And step 205, sending an emergency braking instruction to the train located in the protection area and/or sending a movement authorization instruction excluding the protection area to the train located outside the protection area.
After the protection area is determined, an emergency braking instruction is sent to the train located in the protection area, and the train in the protection area is prevented from continuously running and colliding with the first train and the obstacle.
And/or sending an MA instruction for excluding the protection area to the train outside the protection area to prevent the train outside the protection area from entering the protection area, wherein the MA is the maximum distance for allowing the train to run under any condition. In general, when a ZC calculates an MA, the operation authority of a train is determined according to route information, line data and temporary speed limit information provided by a CI system.
Optionally, in this embodiment of the present invention, step 203 includes searching for a possible travel path on the current route, and/or searching for a possible travel path on the adjacent route.
Specifically, when searching for a possible travel path on the current route, at the position information on the current route, searching forward a path of a first preset distance in the travel direction as a possible travel path, and searching forward a path of a second preset distance in a reverse direction of the travel direction as a possible travel path; for example, after a train collides with an obstacle, the train may continue to run on the current running route in the current running direction; when the collision amplitude is smaller, the possible running path is a section which is forward along the current running direction at the current position information on the current line; or, when the collision amplitude is slightly larger, so that the train is bounced after the collision, namely, the train runs in the reverse direction of the current running direction, the possible running path is a backward section of the current route. The first preset distance and the second preset distance can be set according to the actual condition of the zone to which the ZC belongs.
When searching for a possible travel path on the adjacent line, determining an equivalent position of the position information and an equivalent travel direction of the travel direction on the adjacent line; the equivalent position is determined according to the position information, for example, for a case where the collision amplitude is large, the train may be derailed to an adjacent line, and at this time, at the equivalent position on the adjacent line, a route of a third preset distance is searched forward along the equivalent running direction as a possible running route, and a route of a fourth preset distance is searched forward along a reverse direction of the equivalent running direction as a possible running route, where the third preset distance and the fourth preset distance may be set according to an actual situation of a zone to which the ZC belongs.
Further, in this embodiment of the present invention, the step of determining the equivalent position of the position information and the equivalent moving direction of the moving direction on the adjacent line includes:
searching a position point closest to the position information on the adjacent line, such as an intersection point between a position information point and a vertical line segment of the adjacent line and the adjacent line, wherein the position point is the equivalent position;
and determining the equivalent running direction of the equivalent position on the adjacent line, wherein the equivalent running direction is a possible running direction of an included angle of the running direction within a preset included angle range, the running direction and the equivalent running direction are taken as two vectors, the preset included angle range can be 0-90 degrees, namely the included angle range of the two vectors is 0-90 degrees, and the two vectors are considered as the same direction.
Optionally, in an embodiment of the present invention, the step of obtaining the operation parameter of the first train includes:
and updating the operation parameters when the operation parameters are detected to be changed within a preset time limit.
If the operation parameters of the first train change within a short preset time, for example, the position information and the operation direction change, the ZC updates the operation parameters in time and finally updates the protection zone to ensure the driving safety of the rail transit system.
In the above embodiment of the present invention, after receiving an obstacle signal sent by a first train and used for indicating that the first train monitors an obstacle, a zone controller obtains an operation parameter of the first train; determining a protection area of the first train according to the operation parameters, sending an emergency braking instruction to the train located in the protection area and/or sending a movement authorization instruction excluding the protection area to the train located outside the protection area, and realizing automatic processing of an obstacle mechanism when an obstacle signal is received; the method does not depend on manual processing, and can be suitable for a detection blind area of an FAO system; and the possible running paths of the train on the current line and the adjacent line can be automatically searched, a protection area is established, the train in the protection area is prevented from being influenced, or other trains drive into the protection area of the train, and the influence of obstacles on the running of the track system is reduced.
