Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
As shown in Figure 1, a kind of train safe means of defence can may further comprise the steps:
S101, train safe protective device receive the unavailable message of route track section of track circuit or the transmission of ground collecting device.
After each route laid, track circuit detected idle condition, integraty and the correctness of track section in real time.To detect a certain track section unavailable when track circuit, and then the train safe protective device in cooresponding ground subsystem sends the unavailable message of section; Perhaps by the state of specific ground collecting device 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 because the section that the track section et out of order causes is unavailable etc.; Wherein, the track section fault comprises: track fracture, switch location mistake etc.Wherein, the unavailable message of section comprises the sign and the unavailable location point information of unavailable section.Sign is used to distinguish different track sections, and unavailable location point information is used to identify unavailable particular location initial point or the identification point on the 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 discerned unavailable location point information, and then guarantee that train-installed equipment carries out follow-up judgment processing.
Simultaneously, whether the train safe protective device in the ground subsystem can receive about the unavailable message of the section of route track in real-time monitoring, and under the situation of the unavailable message of section that receives, carries out follow-up treatment scheme.
Wherein, track circuit is to utilize two rail of railway as lead, 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 the ground subsystem particular acquisition equipment can be set, it is used for the section status information of real-time acquisition trajectory circuit.
Need to prove, interlocking equipment in the 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 disturb operation mutually on route separately.Simultaneously, the train safe protective device in the ground subsystem obtains the cooresponding route information of 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 the 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 the route that unavailable section belongs to according to the sign of unavailable section, and definite target train that will or move on this route.
Train safe protective device self can be stored each bar 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 to determine the target train according to the route of this unavailable section ownership, 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 is determined the current running section of target train according to the moving motoring condition information that sends of this target column car owner of current storage.
Being 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 then 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, then 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 the operation of unavailable section or unavailable section when the target train.
S105, train safe protective device judge whether the position relation of this unavailable section and the current running section of target train is non-close; If, execution in step S106 then; 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 then to judge whether the position relation of this unavailable section and the current running section of target train is non-close.Wherein, described non-close position is closed and is: the current running section of unavailable section and target train is at least one track section at 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 the train safe protective device judges that it is non-close drawing this unavailable section and the current running section of target train, 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 parking, train is implemented the safety precaution in the station.
Need to prove that UEM is the form of message that train safe protective device and train-installed equipment are made an appointment, 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 the table 1 should not constitute the qualification 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 relation of the current running section of target train, show this track section unavailable may be since target train self injection section cause, or, caused by other vehicle injection sections or track section fault.
Need to prove that CEM is that train safe protective device and train-installed equipment are made an appointment, and carry the unavailable location point information of unavailable section, for example: CEM can form based on the form of message shown in the 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 the table 2 should not constitute the qualification to it.
When the train safe protective device in the ground subsystem after the target train sends the indication notice, the mobile unit of target train takes appropriate measures according to the indication notice that receives.The mobile unit of target train as shown in Figure 2, can may further comprise the steps the treatment scheme of indication notice:
S201, mobile unit receive the indication notice that the train safe protective device sends.
Whether the real-time monitoring of the mobile unit of target train receives the indication notice that the train safe protective device in the ground subsystem sends.Wherein, the indication notice can be CEM or UEM, is used to indicate mobile unit to adjust corresponding target column vehicle travelling state, to carry out safety precaution.
S202, mobile unit adjust the motoring condition of target train, to carry out safety precaution according to the classification of indication notice.
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 adjusted the motoring condition of target train according to the classification of indication notice, 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 then needed to determine whether the target train is implemented stopping-down according to the unavailable location point information of carrying among the CEM.
Be understandable that, receive at mobile unit under the situation of UEM, show unavailable because other vehicles of section 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 parking, preventing continues to travel in the target train AT STATION causes the accident.
And receive at mobile unit under the situation of CEM, show section unavailable may be because the target train self enters section and causes, perhaps, other vehicles slip into or the track section fault cause.So whether mobile unit need be judged section unavailable caused owing to self taking, and then take appropriate measures.Wherein, concrete judgment mode can for:
Mobile unit judges whether the target train passes through the unavailable location point of unavailable section, if then the indicating target train continues to travel according to default moving velocity; Otherwise, to target train emergency braking, until parking.
When the target train has passed through the unavailable location point of unavailable section, show it is that the section that causes is unavailable, gets final product so mobile unit indicating target train continues to travel according to default moving velocity owing to target train injection section.
And when the target train when crossing the unavailable location point of unavailable section, show since 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 the train station, prevent from that the target train from continuing to travel to cause a serious accident.
In the embodiment of the invention, whether the real-time monitoring of train safe protective device receives the unavailable message of route track section, and under the situation that receives the unavailable message of section, determine the target train that operates on the corresponding route of this unavailable section according to the sign of the section in the unavailable message of section, and draw the target train not under the situation that this unavailable section moved in judgement, send the indication notice of adjusting motoring condition to the target train, with the safe operation that guarantees that the target train is interior AT STATION.In this programme, the train safe protective device is monitored the testing result about the route track in real time, and in time notifies to the corresponding indication of adjusting motoring condition of target train transmission, can effectively guarantee the safety traffic in train AT STATION.
Be understandable that, when the train safe protective device judges that it is non-close drawing unavailable section and the current running section of target train, 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, carry out corresponding judgment, 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 the train station.
Need to prove, the enforcement of the train safe protectiving scheme that present embodiment provided is based on radio communication for example: GSM-R (global system for mobile communications for Railways, whole world railway GSM) and 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 implemented down at CTCS-3 (chinese Train Control System-3, Chinese train control system classification standard 3).
Under the CTCS-3 grade, how train is carried out safety precaution, train safe means of defence provided by the present invention is introduced below.
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 detecting a certain section.
As shown in Figure 3, suppose that train T enters the station and stops, its pairing 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 the slide implantation site is b '.
In order to protect the interior AT STATION driving safety of train, avoid taking place the collision incident, cause heavy losses, see also the diagram of circuit of a kind of train safe means of defence shown in Figure 4, can may further comprise the steps:
S301, RBC receives the unavailable message of section that track circuit sends, and the unavailable message of this section is carried the sign b and the vehicle slide implantation site information b ' of unavailable section.
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 pass, position that obtains this unavailable section and the current orbit section of train T is: the next-door neighbour.
Because at least one track section and be adjacent at interval not between track section b and the current running section a of train T is so pass, the position of this unavailable section and the current orbit section of train T is: be close to.
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 the indication notice of carrying the vehicle slide implantation site information b ' of this unavailable section.
In the present embodiment, whether the real-time monitoring of RBC 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 carried out analysis and judgement, obtain train T and the position relation of unavailable section for being close to as the target train, therefore CEM is notified as indication, in time send to train T, with the interior AT STATION safety traffic of effective assurance train T.
Simultaneously, after the mobile unit of train T receives the indication notice of RBC transmission, will carry out accommodation to train T motoring condition according to indication notice classification.As shown in Figure 5, train T can may further comprise the 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 obtain the vehicle slide implantation site b ' that train T does not carry through CEM.
The indication notice that receives when the mobile unit of train T then 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 is not through vehicle slide implantation site b ', 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, do not have other vehicles to slip or the situation of track fault under, when train T injection section a, RBC can send indication notice CEM to the mobile unit of train T, mobile unit then judges that according to the unavailable location point information of carrying among the CEM drawing train T has passed through unavailable location point, show that at this moment, mobile unit then 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 that this moment, receiving route was A-C, 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, the slide implantation site is e '.
In order to protect the interior AT STATION driving safety of train T, avoid taking place the collision incident, cause heavy losses.A kind of train safe means of defence as shown in Figure 7, can may further comprise the steps:
S501, RBC receives the unavailable message of section that track circuit sends, and the unavailable message of this section is carried the sign e and the vehicle slide implantation site information e ' of unavailable section.
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, RBC judge that the pass, position that 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 real-time monitoring of RBC 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 carried out analysis and judgement, the train T and the unavailable section that obtain as the target train are non-close position relation, 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,, train T motoring condition is carried out accommodation according to indication notice classification.As shown in Figure 8, train T can may further comprise the steps the processing of indication notice:
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.
Because the indication that the mobile unit of train T receives notice is UEM, show that the pass, position of this unavailable section and the current orbit section of train T is non-close, not that to enter the caused section of section by train T unavailable.So mobile unit directly carries out stopping-down to train T,, guarantee the safety when train T passes through a station so that train T is carried out safety precaution.
Be understandable that the wild trajectory section on departure route takes place to slip, RBC should adopt above-mentioned processing.
