Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, a kind of train safe means of defence can comprise the following steps:
S101, train safe protective device receive the unavailable message of route track section of track circuit or the transmission of ground acquisition equipment.
After each route laid, track circuit detected idle condition, integraty and the correctness of track section in real time.A certain track section to be detected unavailable when track circuit, and the train safe protective device in the ground subsystem of correspondence sends the unavailable message of section; Perhaps by the state of specific ground acquisition equipment acquisition trajectory circuit section.The disabled reason of section can comprise: it is unavailable that other vehicles slip the section that causes into the track section, or the section that causes due to the track section et out of order is unavailable etc.; Wherein, the track section fault comprises: track fracture, switch location mistake etc.Wherein, the unavailable message of section comprises sign and the unavailable location point information of unavailable section.Sign is used for distinguishing different track sections, and unavailable location point information is used for identifying unavailable particular location initial point or the identification point on unavailable section, as reference position point, the vehicle of track fault slip into particular location point etc.Be understandable that, the mobile unit of train can be identified unavailable location point information, and then guarantees that train-installed equipment carries out follow-up judgement and processes.
Simultaneously, whether the train safe protective device in ground subsystem can receive about the unavailable message of the section of route track by Real-Time Monitoring, and in the situation that the unavailable message of the section that receives is carried out follow-up treatment scheme.
Wherein, track circuit is to utilize two rail of railway as wire, the electric loop of formation.Whether it can detect track section has car to take, and whether track section is complete etc., and testing result is sent to corresponding train safe protective device.Be understandable that, in ground subsystem, particular acquisition equipment can be set, it is used for the section status information of Real-time Collection track circuit.
Need to prove, interlocking equipment in ground subsystem can be changed track switch and give locking respective rail section for incoming train in advance, open home signal, thereby for train is ready to route, interlocking equipment can be handled many routes simultaneously, and can guarantee that each train does not interfere with each other operation on route separately.Simultaneously, the train safe protective device in ground subsystem obtains route information corresponding to each train, and this route information can comprise label, more specific location information of the different sections of each route etc.Wherein, the train safe protective device obtain the corresponding route information of train mode can for:
After interlocking equipment has been handled route, route information is sent to train safe protective device in ground subsystem; Perhaps, interlocking equipment sends to the train safe protective device with each train route information after the route information request message that receives the transmission of train safe protective device.
Be understandable that, the mode that the train safe protective device obtains the corresponding route information of train is not limited to above-mentioned dual mode.
S102, train safe protective device determine according to the sign of unavailable section the route that unavailable section belongs to, and definite target train that will or move on this route.
Train safe protective device self can be stored each route information, and can determine the route that unavailable section belongs to according to the sign of unavailable section.
Be understandable that, at synchronization, different trains moves on different routes, so when track section is unavailable, the train safe protective device needs the route of section ownership unavailable according to this to determine the target train, and then sends corresponding message to the target train.
S103, train safe protective device obtain the current running section of described target train.
Wherein, the train safe protective device obtain the current running section of target train can be in the following way:
The train safe protective device initiatively sends the motoring condition solicited message to this target train, and according to the described target train that receives according to the solicited message feedback response message, determine the current running section of this target train; Perhaps, the train safe protective device motoring condition information that sends moving according to this target column car owner of current storage is determined the current running section of target train.
Be understandable that, the train safe protective device determines that the current running section mode of target train is not limited to above-mentioned dual mode, as: can also determine in conjunction with the state of track circuit.
S104, train safe protective device judge whether unavailable section is the section that the target train had moved, if so, do not send any indication notice to the target train; Otherwise, execution in step S105.
Be understandable that, when unavailable section occurs in the track section that the target train had moved, at this moment, the train safe protective device need not to send any Indication message to the target train; And just, need to carry out follow-up judgement, and then send corresponding indication notice to the target train during in the current running section of target train the place ahead at unavailable operation by sections or unavailable section when the target train.
S105, train safe protective device judge whether the position relationship of this unavailable section and the current running section of target train is non-close; If so, execution in step S106; Otherwise, execution in step S107.
When the train safe protective device judges that drawing this unavailable section is the section that the target train is moving or off-duty is crossed, continue to judge whether the position relationship of this unavailable section and the current running section of target train is non-close.Wherein, described non-close position relationship is: unavailable section and at least one track section of the current running section of target train interval.
S106, the train safe protective device sends to the target train with UEM (Un-condition Emergency Message, unconditional sudden stop message) as the indication notice.
Wherein, UEM is that the indication that the indicating target train is implemented to brake is immediately notified.
When train safe protective device judgement when to draw this unavailable section and the current running section of target train be non-close, can clearly show not to be that the track section that causes of entering of target train is unavailable, but by other vehicles slip into or the section that causes of track section fault unavailable.So the train safe protective device sends UEM to the target train, directly the indicating target train is implemented emergency braking immediately, until stop, train is implemented the safety precaution in the station.
Need to prove, UEM is the form of message that train safe protective device and train-installed equipment are made an appointment, and for example: the UEM form of message can be:
| Segment number | Variable/packets of information | Remarks |
| 1 | NID_MESSAGE | Message numbering |
| 2 | L_MESSAGE | The message-length that comprises all data |
| 3 | T_TRAIN | According to the time of the definite transmission message of mobile unit clock |
| 4 | M_ACK | Whether mobile unit must confirm this message |
| 5 | NID_LRBG | The identification number of nearest coherent transpoder group |
| 6 | NID_EM | The sudden stop message numbering |
Table 1
Those skilled in the art are understandable that, UEM can form based on the message format of above-mentioned table 1, but the form of message shown in table 1 should not consist of the restriction to it.
S107, the train safe protective device sends to the target train with CEM (Condition Emergency Message, the sudden stop message of having ready conditions) as the indication notice.
Wherein, CEM is the indication notice of the indicating target train adjustment motoring condition of the unavailable location point information in the unavailable message of section of carrying.
When the train safe protective device judges that drawing unavailable section is not non-close (adjacent or identical) with the position relationship of the current running section of target train, show this track section unavailable may be because target train self injection section causes, or, caused by other vehicle injection sections or track section fault.
Need to prove, CEM is that train safe protective device and train-installed equipment are made an appointment, and carries the unavailable location point information of unavailable section, and for example: CEM can form based on the form of message shown in table 2:
Table 2
Those skilled in the art are understandable that, CEM can form based on the message format of above-mentioned table 2, but the form of message shown in table 2 should not consist of the restriction to it.
After the train safe protective device in ground subsystem sent the indication notice to the target train, the mobile unit of target train took appropriate measures according to the indication notice that receives.The treatment scheme of the mobile unit of target train to the indication notice as shown in Figure 2, can comprise the following steps:
S201, mobile unit receive the indication notice that the train safe protective device sends.
Whether the mobile unit Real-Time Monitoring of target train receives the indication notice that the train safe protective device in ground subsystem sends.Wherein, the indication notice can be CEM or UEM, is used to indicate mobile unit and adjusts corresponding target column vehicle travelling state, to carry out safety precaution.
S202, mobile unit is according to the classification of indication notice, and the motoring condition of adjustment aim train is to carry out safety precaution.
Mobile unit is taked the comformability measure according to received indication notice classification, and the target train is carried out safety precaution.Wherein, mobile unit is according to the classification of indication notice, and the motoring condition of adjustment aim train is specifically as follows:
When the indication notice was UEM, mobile unit was to described target train stopping-down;
When the indication notice was CEM, mobile unit needed according to the unavailable location point information of carrying in CEM, determined whether the target train is implemented stopping-down.
Be understandable that, in the situation that mobile unit receives UEM, show section unavailable due to other vehicles slip into or the track section fault cause, it is caused not to be that the target train enters section, so mobile unit is implemented emergency braking to the target train, until stop, preventing continues to travel in the target train AT STATION causes the accident.
And in the situation that mobile unit receives CEM, show section unavailable may be to cause because the target train self enters section, perhaps, other vehicles slip into or the track section fault cause.So whether mobile unit need judge section unavailable caused owing to self taking, and then takes appropriate measures.Wherein, concrete judgment mode can for:
Mobile unit judges whether the target train passes through the unavailable location point of unavailable section, and if so, the indicating target train continues to travel according to default moving velocity; Otherwise, to target train emergency braking, until stop.
When the target train has passed through the unavailable location point of unavailable section, show it is that the section that causes is unavailable due to target train injection section, so continuing to travel according to default moving velocity, mobile unit indicating target train gets final product.
And when the target train when crossing the unavailable location point of unavailable section, show due to other vehicles slip into or the track section that causes of track section fault unavailable, so mobile unit is to target train emergency braking, to carry out safety precaution in train station, prevent from that the target train from continuing to travel to cause a serious accident.
In the embodiment of the present invention, whether train safe protective device Real-Time Monitoring receives the unavailable message of route track section, and in the situation that receive the unavailable message of section, section sign in message unavailable according to section is determined the target train that operates on the corresponding route of this unavailable section, and in the situation that judgement draws the target train does not cross at this unavailable operation by sections, send to adjust the indication notice of motoring condition to the target train, to guarantee the safe operation in the target train AT STATION.In this programme, train safe protective device Real-Time Monitoring is about the testing result of route track, and in time sends the corresponding indication notice of adjusting motoring condition to the target train, can effectively guarantee the safety traffic in train AT STATION.
Be understandable that, when train safe protective device judgement when to draw unavailable section and the current running section of target train be non-close, the indication notice that sends to the target train also can be the CEM that carries unavailable location point information, the unavailable location point information that utilize CEM to carry by the mobile unit of target train this moment, judge accordingly, and draw the target train and do not pass through unavailable location point, therefore the target train is carried out emergency braking, to carry out safety precaution in train station.
Need to prove, the enforcement of the train safe protectiving scheme that the present embodiment provides is based on radio communication for example: GSM-R (global system for mobile communications for Railways, whole world Railway Mobile Radio system) and the equipment such as track circuit, so this programme can be implemented satisfying under the Train Control grade of device requirement, for example: it can be in the lower enforcement of CTCS-3 (chinese Train Control System-3, Train control system classification standard 3).
The below how train is carried out safety precaution under the CTCS-3 grade is introduced train safe means of defence provided by the present invention.
Under the CTCS-3 grade, realize the train safe protective device by RBC, and RBC realizes and the communicating by letter of train-installed equipment by GSM-R; Track circuit detects idle condition, integraty and the correctness of track section in real time, and sends the unavailable message of section to RBC when unavailable a certain section being detected.
As shown in Figure 3, suppose that train T enters the station and stops, its corresponding route track whole process is A-B, comprising: track section a, track section b, track section c.After train T entered the station, in track section a operation, had other vehicles to slip into route track section b this moment, and to slip the implantation site be b '.
In order to protect the driving safety of train in AT STATION, avoid occuring the collision event, cause heavy losses, the diagram of circuit of a kind of train safe means of defence shown in Figure 4 can comprise the following steps:
S301, RBC receive the unavailable message of section that track circuit sends, and the unavailable message of this section is carried the sign b of unavailable section and vehicle and slipped implantation site information b '.
S302, RBC determine that according to the sign b of unavailable section the train T that moves is the target train on the corresponding route of this unavailable section.
S303, RBC obtain the current running section of train T, and judge that obtaining train T off-duty crosses this unavailable section.
S304, RBC are according to the sign b of unavailable section, and the position relationship that obtains this unavailable section and the current orbit section of train T is: the next-door neighbour.
Due at least one track section of interval and be adjacent not between track section b and the current running section a of train T, so the position relationship of this unavailable section and the current orbit section of train T is: the next-door neighbour.
S305, RBC sends to train T with CEM as the indication notice, and T carries out the speed adjustment with the indication train.
Wherein, CEM is that the vehicle that carries this unavailable section slips the indication notice of implantation site information b '.
In the present embodiment, whether the RBC Real-Time Monitoring receives the unavailable message of section that track circuit sends, and when receiving the unavailable message of section, the unavailable message of this section is analyzed judgement, obtain train T and the position relationship of unavailable section for being close to as the target train, therefore with CEM as the indication notice, in time send to train T, the safety traffic with effective assurance train T in AT STATION.
Simultaneously, after the mobile unit of train T receives the indication notice of RBC transmission, will according to indication notice classification, carry out accommodation to train T motoring condition.As shown in Figure 5, train T can comprise the following steps the processing of indication notice:
S401, the mobile unit of train T receive the indication notice that RBC sends, and this indication notice is CEM.
S402, mobile unit detect and to obtain vehicle that train T carries through CEM and slip implantation site b '.
The indication notice that receives when the mobile unit of train T needs to detect the current run location of train T, to carry out follow-up processing during for CEM.
S403, mobile unit carries out stopping-down to train T.
Because train T slips implantation site b ' through vehicle, show that this unavailable section is not caused by train T injection section, but other vehicles slip into or the track section fault cause, so the mobile unit of train T is taked the stopping-down measure to train, so that train T is carried out safety precaution, guarantee the safety traffic in train T AT STATION.
Be understandable that, in the situation that do not have other vehicles slip into or the track fault, when train T injection section a, RBC can send to the mobile unit of train T indication notice CEM, mobile unit draws train T according to the unavailable location point information judgement of carrying in CEM and has passed through unavailable location point, show that at this moment, mobile unit needn't be adjusted train T motoring condition because train T injection section a has caused the unavailable of track section a.
Another embodiment as shown in Figure 6 still describes with the protection of the train safe under the CTCS-3 grade.Same hypothesis realizes the train safe protective device by RBC, and RBC realizes and the communicating by letter of train-installed equipment by GSM-R; Track circuit detects idle condition, integraty and the correctness of track section in real time, and detect a certain section when unavailable train safe protective device to RBC send the unavailable message of section.
Suppose that train T only passes through a station, do not stop, this moment, receiving route was A-C, and comprising: track section a, track section b, track section c, departure route comprises track section e.After supposing that train T enters the station, in track section a operation, have this moment other vehicles to slip track section e into departure route, slipping the implantation site is e '.
In order to protect the driving safety of train T in AT STATION, avoid occuring the collision event, cause heavy losses.A kind of train safe means of defence as shown in Figure 7, can comprise the following steps:
S501, RBC receive the unavailable message of section that track circuit sends, and the unavailable message of this section is carried the sign e of unavailable section and vehicle and slipped implantation site information e '.
S502, RBC are according to the sign e of unavailable section, and determining the train T that moves on the corresponding route of unavailable section is the target train.
S503, RBC obtain the current running section of train T, and judge that obtaining train T off-duty crosses described unavailable section.
S504, the position relationship that the RBC judgement obtains this unavailable section and the current running section of train T is: non-close.
S505, RBC sends to train T with UEM as the indication notice.
Wherein, UEM carries out the indication notice of stopping-down for indication train T.
In the present embodiment, whether the RBC Real-Time Monitoring receives the unavailable message of section that track circuit sends, and when receiving the unavailable message of section, the unavailable message of this section is analyzed judgement, obtaining as the train T of target train and unavailable section is non-close position relationship, therefore with UEM as the indication notice, in time send to train T, carry out the actv. safety precaution so that train T is passed through a station.
After the mobile unit of train T receives the indication notice of RBC transmission, according to indication notice classification, train T motoring condition is carried out accommodation.As shown in Figure 8, the processing of train T to the indication notice can comprise the following steps:
S601, mobile unit receive the indication notice that RBC sends, and this indication notice is UEM.
S602, mobile unit carries out stopping-down to train T.
The indication notice that receives due to the mobile unit of train T is UEM, shows that the position relationship of this unavailable section and the current orbit section of train T is non-close, is not that to enter the caused section of section by train T unavailable.So mobile unit directly carries out stopping-down to train T, so that train T is carried out safety precaution, guarantee the safety when train T passes through a station.
Be understandable that, the wild trajectory section on departure route slip into, RBC should adopt above-mentioned processing.
