Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a wireless block center and a method for controlling train intrusion protection by the wireless block center.
Background
The radio block center device is a core device of the train control system. The Radio Block Center (RBC) acquires the state information of the access road and the block subarea from the interlocking equipment, calculates the train running permission according to the train position, and sends a running permission command to the vehicle-mounted equipment in a wireless mode to ensure the safe running of the train. During the process that the train is authorized to enter the station and stop, the route is changed from the normal route to the passing route, and finally the train is unlocked. After the route is changed into 'passing', the safety of the current train cannot be guaranteed due to the fact that a track circuit is in fault, or the fact that the route is occupied by the current train or other trains under the condition that the train enters the last section of the route, and the travelling of the authorized train is possibly damaged.
When the train is pressed into the receiving route, the route state is changed from 'normal route' to 'passing through'. As shown in fig. 1, in the prior art, an interlock can avoid an abnormality in an access through a three-point check logic, the interlock can refresh an access state for an RBC, and the RBC guarantees driving safety according to the access state of the interlock. However, in some situations, such as poor shunting of the track circuit, axle counting failure or other situations, occupation by a "foreign object" that cannot be detected by the interlock device may occur, which may bring safety hazards to driving. Meanwhile, in the process of authorized train entering and stopping, after the train receiving access is unlocked, the RBC cannot acquire access state information from the interlocking device, cannot ensure whether the unlocked access is abnormal or not, and cannot ensure the safety of the authorized train. In addition, after the train receiving access is unlocked, the interlocking device can handle a guide access of a station track where the authorized train is located, and can access other trains from the outside of the station, so that the authorized train can possibly collide with other trains. When the access is unlocked, the RBC still maintains the movement authorization of the train to the access terminal, and possibly brings harm to the train with the authorization.
When an authorized train ATP1 enters the downlink receiving route X- > XI, the route state of X- > XI is changed from 'normal route' to 'passing' as shown in FIG. 2. The train ATP1 does not drive into an IG station track, and oppositely enters into the IG station track from a descending direction, at the moment, the interlocking device considers that the X- > XI occupation sequence is abnormal through three-point check logic, the access state is set to be unavailable, the information is transmitted to the RBC device, and then the RBC can make a safety response to the situation: UEM is given to ATP1, and the driving permission of ATP1 is cancelled.
When an authorized train ATP1 enters the downlink receiving train route X- > XI, the route state of X- > XI is changed from 'normal route' to 'passing through', or finally to 'route unlocking', as shown in FIG. 3. When ATP1 drives into an IG track and oppositely drives into ATP2 from the downstream direction to enter the IG track, the interlocking device cannot judge whether the occupation pressure of X- > XI is abnormal through three-point check logic, so that the state that an access is unavailable cannot be transmitted to RBC equipment, and the RBC cannot make a safety response to the situation.
In the above scenario, whether the access is unlocked or not, the RBC should guarantee the driving safety of the train in the station. Therefore, when a train performs station operation, it is necessary to research a scheme for monitoring the driving safety of other train intrusion prevention through RBC.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the defects of the prior art, the invention discloses a method for controlling train break-in protection by a radio block center, which comprises the steps that the radio block center receives an authorized train route state sent by interlocking equipment, and judges whether other train signals in operation exist in the authorized range of an authorized train according to the route state of the authorized train;
after the train enters the train receiving approach, the approach delay unlocking can be triggered. Due to different interlocking processing of various manufacturers, the time for triggering the route unlocking and the actual time for unlocking the route may be different, but the route is finally unlocked after the train enters the station track and stops. When the access is unlocked, the interlock sends an access unlocking message to the RBC.
In an embodiment of the invention, the route state of the train includes any one of a normal route, a passing route or a route unlocking. The real-time protection of train driving safety comprises access unlocking authorization protection and other train intrusion protection.
In a specific embodiment of the invention, during the train station-entering and stopping process, RBC is divided into two aspects of non-unlocking and unlocking of the train-receiving access according to the access state of interlocking transmission, and after the access is unlocked, "access unlocking authorized protection" is started to supervise and protect the driving safety. Meanwhile, no matter whether the train receiving access is unlocked or not, the RBC immediately starts 'other trains break into the protection' to ensure the driving safety of the trains in the station when receiving the access state sent by the interlocking equipment and being 'passing'. In a specific embodiment of the present invention, when the route status of the authorized train is passing, the route of the authorized train is not unlocked; when the radio block center receives the route state sent by the interlocking device and changes from 'normal route' to 'passing', the RBC immediately starts 'other train break-in protection'. Because the access road is not unlocked, the RBC can receive the train receiving access road information of the interlocking equipment in real time and judge whether other running train signals exist or not; or the RBC equipment can check whether other trains exist in the authorization range by refreshing the route information in the route authorization range of the authorized train in real time.
When the train receiving access is not unlocked, other trains running in the same direction or in the reverse direction in the train authorization range of the station enter the train and call RBCs, or other trains running in the same direction slide into the train authorization range, the RBC immediately sets an unavailable mark for the train receiving access, and the mark can cause the RBC to send unconditional emergency stop (UEM) to the train receiving access. If no other train signal exists, the radio block center keeps the movement authorization of the authorized train on the route.
In a specific embodiment of the present invention, when the radio block center receives that the route status sent by the interlock device changes from "passing" to unlocking, and the route status of the authorized train is route unlocking, the route of the authorized train is unlocked, and the RBC continues to maintain "other train intrusion prevention". Because the access is unlocked, the RBC cannot acquire the receiving access state information, and the RBC equipment can check whether other trains exist in the authorization range in real time. The radio block center acquires the access information in the access authorization range of the authorized train in real time; and according to the route information in the route authorization range of the authorized train.
After the train receiving access is unlocked, other trains running in the same direction or in the reverse direction in the train access authorization range call RBCs, or other trains running in the same direction slide into the train authorization range, and then the RBCs immediately send unconditional emergency stop (UEM) to the trains. If no other train signal exists, the radio block center keeps the movement authorization of the authorized train on the route.
The invention also discloses a radio block center, as shown in fig. 5, the radio block center comprises a receiving unit, a transmitting unit and a receiving unit, wherein the receiving unit is used for receiving the authorized train route state sent by the interlocking equipment; the judging unit is used for judging whether other running train signals exist in the authorization range of the authorized train or not according to the fact that the received train access state sent by the interlocking device is that the train is passing; and the command sending unit is used for sending an unconditional emergency stop command to the authorized train when other train signals in operation exist in the authorized range of the authorized train.
With regard to the apparatus in the above-described embodiment, the specific manner in which each unit performs the operation has been described in detail in the embodiment related to the method, and will not be described in detail here.
The technical solution of the present application will be further described in detail with reference to specific examples.
Unlocking protection for a train route:
before the train route is unlocked, the two situations of 'normal route' and 'passing' are divided according to the position of the train, the route state can be refreshed for the RBC by the interlocking system under the two situations, and the RBC guarantees the driving safety according to the route state of the train sent by the interlocking system.
When the route state is 'normal route' and 'passing', the RBC can acquire the route state of the train from the interlock, so that when the route state changes, the RBC can acquire and refresh the route state in time, supervise and update the train movement authorization in real time according to the route state, and can ensure the driving safety.
After the train route is unlocked, the interlocking system does not refresh the unlocked route state for the RBC any more, and even the guided vehicle receiving route in any direction including the station track can be handled. At this time, the RBC must ensure the train driving safety of the station track train. It should be noted that, when a station track is occupied by a vehicle, the interlock cannot handle a normal vehicle receiving route from outside the station to the station track, that is, the interlock system has a safety protection function. Therefore, when the train occupation exists in the station track, the protection that the RBC receives the interlocking to handle the normal train receiving access of the station track is out of the research scope of the invention.
The train route unlocking authorization protection comprises the following steps: the train enters the route to unlock the authorization protection and transacts the reverse guide to receive the train.
The same-station track handles train route unlocking authorization protection of the same-direction guided vehicle receiving, as shown in fig. 6, after the train route is unlocked, when RBC receives an instruction of the same-direction guided vehicle receiving route handled by an interlocking system, for example, the same-direction guided train enters SF- > SI, the train is immediately supplemented with a guide mode authorization with an unchanged authorization terminal point, so that the train (ATP 1) enters a guide mode, and the driving safety supervision responsibility of the train (ATP 1) is transferred to a driver; the step of reissuing the train (ATP 1) with the guide mode authorization with the unchanged authorization terminal point comprises the step that the RBC cannot distribute the unlocked train route to other trains (ATP 2), namely, (ATP 2) cannot obtain the route SF- > SI authorization and enters the station track in a visual mode.
In a specific embodiment of the present invention, as shown in fig. 7, a train ATP1 with a Mobile Authorization (MA) enters an IG station track from a downlink transit route X- > XI, the train ATP1 is in a full monitoring mode (FS), the route X- > XI is unlocked, and the RBC keeps the authorization of the train ATP1 to the XI signaler unchanged, and simultaneously starts "route unlocking authorization protection" immediately. As shown in fig. 8, according to the station operation requirement, after receiving the downlink guide pickup route of the X- > XI route handled by the interlocking system, the RBC immediately gives the train ATP1 a guidance mode authorization to the XI signal machine because the X- > XI route is changed into the guidance route, and the ATP1 changes to the guidance mode (OS) to operate, and the driver is responsible for the driving safety of the ATP 1.
As can be seen from fig. 8, since the route X- > XI has already been allocated to the train ATP1 by the RBC as a movement authorization, the RBC cannot allocate the route X- > XI to the train ATP2 as an authorization, but the train ATP2 can enter the IG station track in a visual mode, and at this time, the driver needs to drive and be responsible for the driving safety of the train ATP2 to complete the reconnection operation.
As shown in fig. 9, after the train (ATP 1) enters the route for unlocking, for example, SF- > SI enters the route for unlocking, when the RBC receives a command of the reverse guidance receiving route handled by the interlock system, the RBC considers that there may be an operation of entering the station track by the reverse receiving, and immediately sends an unconditional emergency stop (UEM) command to the train (ATP 1), and the train (ATP 1) stops in a rail-falling mode, so as to avoid collision between the train and other trains; and meanwhile, the RBC distributes the route (X- > XI) reverse to the route of the train (ATP 1) to the train (ATP 2) as authorization, authorizes the guidance mode of the train (ATP 2) transmitted to the corresponding terminal signal (XI signal), and enables the train (ATP 2) to change into the guidance mode.
In one embodiment of the present invention, as shown in fig. 10, a train ATP1 with a Movement Authorization (MA) enters an IG station track from an uplink pickup route SF- > SI, the train ATP1 is in a full monitoring mode (FS), SF- > SI is unlocked, and RBC keeps the Movement Authorization (MA) to the SI signal unchanged for the train ATP1, and simultaneously starts "route unlocking authorization protection" immediately.
As shown in fig. 11, according to the station operation requirement, after the RBC receives the downlink guide pickup route of the interlocking system transacting the route X- > XI, because the route direction X- > XI conflicts with the authorized direction of the train ATP1, the RBC immediately sends an unconditional emergency stop (UEM) to the train ATP1, and the train ATP1 turns to the rail-down mode for stopping. Meanwhile, the RBC distributes the route X- > XI to the train ATP2 as authorization, the train ATP2 is authorized to be sent to a guide mode of an XI signal machine, the train ATP2 is converted into the guide mode, and a driver drives the train and is responsible for the driving safety of the train ATP2 to complete reconnection operation.
The protection against the intrusion of other trains comprises the protection against the intrusion of other trains with the same direction in the authorized range in the train entering process and the protection against the intrusion of other trains with the reverse direction in the authorized range in the train entering process.
As shown in fig. 12, when the route status sent by the interlock device and received by the radio block center changes from "normal route" to "passing," the RBC immediately starts "other train break-in protection". Because the access is not unlocked, in most cases, the interlock can avoid abnormality in the access through a three-point check logic, but in some scenes, occupation of a foreign object which cannot be detected by the interlock device may occur, so that potential safety hazards may be brought to driving, the receiving access information of the interlock device can be received in real time inside the RBC, and the RBC device can check whether other trains exist in an authorization range through the access information refreshed in real time.
In an embodiment of the invention, when the train receiving access is not unlocked, other trains running in the same direction in the train authorization range of the station entering call the RBCs, or other trains running in the same direction slide into the train authorization range, and then the RBCs immediately set an unavailable mark for the train receiving access.
When the authorized ATP1 crosses the X signal machine through the downlink receiving route X- > XI, the RBC calculates the authorization to the XI signal machine for the ATP1, as shown in figure 13, the route X- > XI is changed from 'normal route' to 'passing', the RBC immediately starts 'other train break-in protection', at the moment, the train ATP1 is in a full monitoring mode (FS), and the authorization to the XI signal machine is kept unchanged for the train ATP1 by the RBC. After ATP2 registers and reports the position to the RBC, the RBC considers that there are other trains running in the same direction in the authorized range of ATP1, as shown in fig. 14, the RBC immediately sets an unavailable flag to the pickup route X- > XI, which may cause the RBC to send an unconditional emergency stop (UEM) to ATP1, and avoid the ATP1 and ATP2 from colliding with each other.
In one embodiment of the invention, when the receiving route is not unlocked, other trains running in the reverse direction are called by RBC in the train authorized range of the station, or other trains running in the reverse direction enter the train authorized range, and then the RBC immediately sets an unavailable mark for the receiving route.
When the authorized ATP1 crosses the SF signal machine through the uplink receiving route SF- > SI, the RBC calculates the authorization from the ATP1 to the SI signal machine, as shown in figure 15, the SF- > SI is changed from 'normal route' to 'passing', the RBC immediately starts 'other train break-in protection', at the moment, the train ATP1 is in a complete monitoring mode (FS), and the RBC keeps the authorization from the train ATP1 to the SI signal machine unchanged. After ATP2 registers and reports the location to the RBC, the RBC considers that there are other trains running in reverse direction within the authorized range of ATP1, as shown in fig. 16, the RBC immediately sets an unavailable flag to the pickup route SF- > SI, which may cause the RBC to send an unconditional emergency stop (UEM) to ATP1, and avoid ATP1 colliding with ATP 2.
In another aspect of train protection of the present invention, as shown in fig. 17, when the route status sent by the radio block center from the interlock device changes from "passing" to unlocking, the RBC continues to maintain "other train break-in protection". Because the access is unlocked, the RBC cannot acquire the receiving access state information, and the RBC equipment can check whether other trains exist in the authorization range in real time.
After the train receiving access is unlocked, other trains running in the same direction in the train access authorization range call RBCs, or other trains running in the same direction slide into the train authorization range, and then the RBCs immediately send unconditional emergency stop (UEM) to the trains.
In one embodiment of the present invention, as shown in fig. 18, an authorized ATP1 is accessed to the IG from the downlink access route X- > XI, at this time, the train ATP1 is in the full monitoring mode (FS), the RBC calculates the authorization to the XI signal from the ATP1, and the route state X- > XI is "during the whole stop after the passage" becomes "access unlock", the RBC continuously keeps "other train break-in protection". As shown in fig. 19, after ATP2 registers and reports the position to RBC, RBC considers that there are other trains running in the same direction within the authorization range of ATP1, and UEM is immediately sent to ATP1, ATP1 stops in the rail forward mode, and ATP1 and ATP2 do not end up.
After the train-receiving access is unlocked, the RBC immediately sends an unconditional emergency stop (UEM) to the train when the train entering the station breaks into other trains in a reverse direction within the authorized range of the train.
In an embodiment of the present invention, an authorized ATP1 accesses to the IG through an uplink pickup route SF- > SI, at this time, the train ATP1 is in a full monitoring mode (FS), and the RBC calculates authorization to the SI signal for the ATP1, as shown in fig. 20, during the whole station stop process after the SF- > SI route state is changed from "passing through" to "route unlocking", the RBC continuously keeps "other train break-in protection". As shown in fig. 21, after ATP2 registers and reports to the RBC, the RBC considers that there are other trains running in reverse direction within the authorization range of ATP1, UEM is immediately sent to ATP1, ATP1 stops in the rail-forward mode, and ATP1 and ATP2 are prevented from colliding.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
