Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
In order to better understand the technical scheme provided by the embodiment of the invention, a method for detecting the occupation condition of a train on a track in the prior art is described first.
In the case of the conventional CTCS-3 class track circuit, the handover RBC is responsible for transmitting handover advance notice information (vehicle-mounted device ID, transponder group ID of RBC boundary, train data, etc.), route request information, handover notice information, handover confirmation information, and handover cancellation information to the takeover RBC. The takeover RBC is responsible for transmitting route information and takeover train information to the handover RBC. The existing system does not need to pay attention to the section state of the section and does not need to carry out section occupation check because no section trackside detection equipment exists. However, the above scheme relies on the track circuit for train occupation inspection, and the track circuit is paved on a large scale in a severe environment or on the existing trackless line, so that the cost is high and the later maintenance is difficult.
In the prior art, aiming at a virtual section without a track circuit, train position information is sent to a handover RBC (radio frequency control) by an ATP (adenosine triphosphate) period of a vehicle-mounted device, the position report is updated every time the train passes through one transponder, the handover RBC acquires the latest relevant transponder group in the train position report information, and a safety envelope of the train is constructed by combining kilometer scale information, headstock offset information, train integrity information and train length information of the transponder group, so that the train is mapped to the virtual section, and occupation inspection of the virtual section is completed. That is, the above scheme is that the inspection of train occupation in the process of RBC right-handed over is described in terms of a single RBC, and is not studied, since the handover boundary (i.e. right-handed over point) is set at the intersection point between the reference virtual section and the target virtual section, in the process of train right-handed over, if the train is in the range of the handover RBC, the handover RBC can acquire the position information of the train, and the inspection of train occupation on the virtual section is completed according to the existing technology, but for the take-over RBC, since the take-over RBC may not be connected with the train before the take-over train, i.e. the inspection of train occupation of the virtual section cannot be acquired in real time, if the train has a fault such as wireless timeout in the range of the handover RBC, the take-over RBC cannot detect the fault, and the train is likely to enter the take-over range during the fault, so that the take-over RBC has a dead zone condition for the inspection of train occupation of the section, and in the process of right-handed over, there is exists a security risk in the process of security risk.
In summary, in the prior art, the situation that the taking over RBC cannot acquire the train position report in the right-crossing process is not considered, according to the above technology, the taking over RBC cannot set the occupation or the idle of the virtual section in the range of the taking over RBC, the simple setting to be idle may cause the security risk in the right-crossing process, and the direct setting to be occupied may cause the right-crossing failure to affect the usability of the system.
Example 1
Fig. 1 is a flowchart of a method for determining a status of a virtual section according to an embodiment of the present invention, where the method may be performed by a device for determining a status of a virtual section, and the device may be configured in an electronic device that carries a function for determining a status of a virtual section.
Referring to the state determining method of the virtual section shown in fig. 1, the method is applied to take over a radio block center RBC, and includes:
s110, acquiring section interaction information in the reference virtual section which is administrated by the RBC.
The takeover RBC and the handover RBC can be determined according to the running condition of the train. For example, if the train is from RBC a The jurisdiction is running to RBC b Jurisdictional, RBC a To handover RBCs, RBCs b To take over RBCs.
Wherein, the reference virtual section refers to the area of the trackless circuit administered by the handover RBC. The section interaction information refers to information that the handover RBC transmits to the takeover RBC. Specifically, the zone interaction information may be generated from interaction information between the train and the handover RBC within the reference virtual zone.
Specifically, the takeover RBC may obtain zone interaction information within the reference virtual zone administered by the handoff RBC. It should be noted that, the handover RBC may send the section interaction information to the take-over RBC according to a preset period. The embodiment of the invention does not limit the length of the preset period, and can be set by a technician according to experience.
S120, determining the current state of the target virtual section which takes over the jurisdiction of the RBC according to the section interaction information.
The target virtual section refers to the area of the trackless circuit governed by the connecting tube RBC. The current state refers to the state of the target virtual section at the current time.
The embodiment of the invention provides a state determination scheme of a virtual section, which is applied to take over RBC, and section interaction information in a reference virtual section administrated by the RBC is obtained; and determining the current state of the target virtual section governed by the RBC according to the section interaction information. According to the scheme, the current state of the target virtual section is determined by taking over the information interaction between the RBC and the handover RBC, the accuracy of the determined target virtual section is improved, and the running safety of the train is further improved. Meanwhile, the embodiment of the invention greatly reduces the use of the physical section with the track circuit and reduces the cost by introducing the reference virtual section and the target virtual section.
Example two
Fig. 2A is a flowchart of a method for determining a state of a virtual zone according to a second embodiment of the present invention, where the operation of determining, based on zone interaction information, a current state of a target virtual zone governed by taking over RBCs is further refined to "determining, based on a train type and a train sequence in the zone interaction information, a current state of a target virtual zone governed by taking over RBCs" so as to perfect a determination mechanism of the current state, based on the above embodiments. In the portions of the embodiments of the present invention that are not described in detail, reference may be made to the descriptions of other embodiments.
Referring to fig. 2A, the method for determining the state of the virtual section includes:
s210, acquiring section interaction information in the reference virtual section which is administrated by the RBC.
S220, determining the current state of the target virtual zone governed by the RBC according to the type and the sequence of the trains in the zone interaction information.
The train sequence is a sequencing result of the distance between the trains in the reference virtual section and the right-of-hand points. The crossing point is also called crossing boundary point, which is the crossing point of the reference virtual section and the target virtual section, and refers to the point where the transfer RBC transfers the authority of controlling the train to the take over RBC. For example, the intersection weight point may be determined according to the boundary point of the reference virtual section and the boundary point of the target virtual section.
Optionally, the train type is determined based on a communication condition of the train within the reference virtual zone with the handover RBC. In particular, the train types may include communication trains and fault trains. The faulty trains may include non-communication trains and hidden trains, among others.
Specifically, if normal communication is performed between any train in the reference virtual section and the handover RBC and the communication delay time does not exceed the preset delay time, the train type of the train is a communication train; if the communication delay time between any train in the reference virtual section and the handover RBC exceeds the preset delay time, the communication between the active cancellation of the train and the handover RBC or the communication information between the train and the handover RBC is not satisfactory, the train type of the train is a non-communication train; if no communication has been made between any train within the reference virtual zone and the handover RBC, but the handover RBC detects that the train may be present on the reference virtual zone, the train type of the train is a hidden train. It should be noted that, the embodiment of the present invention does not limit the preset delay time, and may be set by a technician according to experience or needs.
It should be noted that, the handover RBC may determine whether the reference virtual zone administered by the handover RBC may have a hidden car according to the administered zone with a track circuit (i.e., the train must be detected when entering the administered zone with a track circuit by the handover RBC); or the handover RBC may determine from the axle counting detection device whether there is a potential for a hidden car in the reference virtual zone administered by the handover RBC.
It can be appreciated that by determining the train type with reference to the communication conditions of the trains within the virtual zone and the handoff RBCs, the accuracy of the determined train type is improved.
It should be noted that, the handover RBC may determine a train type and a train sequence of the train in the reference virtual section according to the information sent by the train in the reference virtual section; the handover RBC sends section interaction information comprising the train type and the train sequence to the takeover RBC; and the takeover RBC determines the current state of the target virtual section governed by the takeover RBC according to the type of the train and the sequence of the train in the section interaction information.
In an alternative embodiment, determining the current status of the target virtual zone administered by the RBC according to the train type and train order in the zone interaction information includes: according to the train sequence, taking the train with the closer distance crossing weight point in the reference virtual section as a target train; and determining the current state of the target virtual section governed by the RBC according to the type of the train of the target train.
In order to improve accuracy of the determined current state, a train closest to the traffic right point in the reference virtual section may be used as the target train. Wherein the target train refers to a train that may be used to determine the current state of the target virtual zone. The target train is a train that does not enter the target virtual zone.
Specifically, according to the train sequence, taking the train closest to the right-of-hand point in the reference virtual section as a target train; and determining the current state of the target virtual section governed by the RBC according to the type of the train of the target train.
It can be understood that by introducing the target train and determining the current state of the target virtual section according to the train type of the target train, the situation that the current state of the target virtual section cannot be accurately determined when the number of trains in the reference virtual section is greater than one is avoided, and the accuracy of the determined current state is improved.
When determining the current state of the target virtual section, the current state of at least part of the target virtual section which is closer to the crossing point is determined according to the train type of the target train, and then the current state of all the target virtual sections is determined by extension. Preferably, the current state of at least part of the target virtual section closest to the intersection weight point is determined.
In an alternative embodiment, determining the current status of the target virtual zone administered by the RBC according to the train type of the target train includes: and if the train type of the target train belongs to the communication train, determining that the current state of the target virtual section is an idle state.
Wherein the idle state may be used to indicate that the target virtual zone allows other trains than the target train to be driven in.
For example, see the schematic diagram of the idle state shown in fig. 2B. The trains A and B travel from the station 1 to the station 2, the trains on the reference virtual section comprise the trains A and B, and if the train A is a target train and the train type of the train A is a communication train, the current state of the target virtual section is an idle state.
In another alternative embodiment, determining the current status of the target virtual zone administered by the RBC according to the train type of the target train includes: and if the train type of the target train belongs to the fault train, determining that the current state of the target virtual section is a fault occupation state.
Wherein the fault occupancy status may be used to instruct the target virtual zone to prohibit other trains than the target train from entering.
It can be understood that by introducing the idle state and the fault occupation state, the situation that the position of the train on the target virtual section cannot be accurately determined and collision occurs when at least two trains enter the target virtual section is avoided, and the safety of running of the trains on the target virtual section is improved.
Optionally, if the train type of the target train belongs to the fault train, determining that the current state of the target virtual section is the fault occupancy state includes: if the train type of the target train is a non-communication train, determining that the current state of the target virtual section is a non-communication train fault occupation state; and if the train type of the target train is the hidden train, determining the current state of the target virtual section as the fault occupancy state of the hidden train.
The non-communication train fault occupation state refers to a state that a target virtual section is occupied by a target train of which the train type is a non-communication train. The hidden car fault occupancy state refers to a state in which the target virtual section is occupied by a target train of which the train type is a hidden car.
For example, see the schematic diagram of the non-communication train fault occupancy state shown in fig. 2C. The trains A and B travel from the station 1 to the station 2, the trains on the reference virtual section comprise the train A and the train B, and if the train A is a target train and the train type of the train A is a non-communication train, the current state of the target virtual section is a non-communication train fault occupation state.
For example. See the schematic diagram of the hidden car fault occupancy state shown in fig. 2D. The trains A and B travel from the station 1 to the station 2, the trains on the reference virtual section comprise the train A and the train B, and if the train A is a target train and the train type of the train A is a hidden train, the current state of the target virtual section is a hidden train fault occupied state.
It can be appreciated that by introducing the non-communication train fault occupancy state and the hidden train fault occupancy state, the fault occupancy state is subdivided, and the accuracy of the determined fault occupancy state is improved.
The embodiment of the invention provides a state determination scheme of a virtual zone, which is used for determining the current state operation of a target virtual zone governed by taking over RBC according to zone interaction information, refining the operation into the determination of the current state of the target virtual zone governed by taking over RBC according to the train type and train sequence in the zone interaction information, and perfecting a determination mechanism of the current state. According to the scheme, the current state of the target virtual section is determined by introducing the train type and the train sequence, so that the accuracy of the determined current state of the target virtual section is improved, and the driving safety of the train in the process of handing over RBC and taking over RBC for right-of-hand.
On the basis of the technical scheme, after the current state of the target virtual section is determined, the RBC is handed over to continuously send new section interaction information to the RBC according to a preset period; the takeover RBC updates the train type of the target train according to the new section interaction information; and updating the current state of the target virtual section according to the updated train type of the target train and/or the integrity of the target train.
It should be noted that, referring to the train on the virtual zone, the interactive information may be periodically sent to the handover RBC, and the handover RBC may update the zone interactive information according to the interactive information.
For example, if the trains on the reference virtual section include a train a and a train B, the train a is a target train, and the train type of the train a is a non-communication train, the current state of the target virtual section is a non-communication train fault occupancy state. Further, if the train type of the train a is changed into a communication train and the train length of the train a is unchanged in the new section interaction information received by the takeover RBC after the preset period, the takeover RBC adjusts the current state of the target virtual section from the non-communication train fault occupancy state to an idle state, namely, the fault is relieved.
For example, if the trains on the reference virtual section include a train a and a train B, the train a is the target train, and the train type of the train a is the hidden train, the current state of the target virtual section is the hidden train fault occupancy state. Further, if the train type of the train a is changed into a communication train in the new section interaction information received after the RBC is taken over in the preset period, a certain safety risk exists in automatically updating the current state of the target virtual section according to the train type, so that fault release can be realized only in a manual confirmation mode, hidden vehicles cannot exist in the target virtual section, and driving safety is guaranteed. It should be noted that, the embodiment of the present invention does not limit the manner of manual confirmation, and the embodiment may be set by a technician according to experience. For example, the manner of manual confirmation may include a manner of manually confirming whether the axle counting detection devices on both sides of the target virtual section are clear and/or manually unlocked.
The embodiment of the invention combines a train right-crossing mechanism of the train in actual operation, provides a corresponding fault release method on the basis of determining the current state of the target virtual section, ensures the running safety of the train, improves the running efficiency of the train and improves the usability of the target virtual section.
