Description

The train tracking operation method and CBTC systems of no secondary track detection device

Technical field

The present invention relates to technical field of rail traffic, and in particular to a kind of train tracking fortune of no secondary track detection device Row method and CBTC systems.

Background technology

(Communication Based Train Control System, the train based on communication is certainly by traditional CBTC Autocontrol system) framework see attached drawing 1, which mainly includes:Positioned at the automatic train monitoring of being used for realization of control centre Equipment (such as control centre), wireless-transmission network (such as dcs, Distributed Control System, letter Claim DCS), mobile unit, ground installation.Wherein, ground installation includes:ZC (Zone Controller, zone controller), connection Lock system CI, trackside semaphore, trackside meter shaft, trackside transponder etc..

Based on traditional CBTC systems are controlled with ground, train actively receives the control of ZC by earthward ZC registrations, and Position actively is reported to ZC, ZC carries out train sequence according to train position, the neighbouring relations of train on circuit is calculated, according to front truck The tailstock calculates MA for rear car, the interaction of two-way wireless communication with realizing car information by continuous car, and then realizes and be based on mesh Train tracking operation under the movable block standard of mark-distance.

In ZC control train tracing processes, to ensure the safe operation of train, it is necessary to be that train is screened, such as Fig. 2 institutes Show, train screening function be train mobile authorization calculate preposition function, by screen determine train front and back or One of with the presence or absence of hide train.After only communication train (CT) completes screening, ZC can be just that it calculates mobile authorization (MA: Movement Authority), it can normally upgrade to CBTC ranks and receive the control of ZC.

Train screening is divided into front end screening and rear end screening.The completion requirement of front end screening remembers shaft end for train head distance Point is no more than the most short vehicle commander being likely to occur on circuit, and (front screening areas includes 1 to current of traffic front screening areas Or 2 note axis regions) idle.The completion requirement that rear end is screened is not more than on circuit to go out for last vehicle of train distance note shaft end point Existing most short vehicle commander, one, current of traffic rear note axis section are idle.

Train control system of future generation based on truck traffic is different from traditional CBTC systems, as shown in figure 3, which employs with Train autonomous control is the decentralised control model of core, and by way of front and rear train direct communication, train obtains front vehicle position With the information such as the speed of service, the speed that mobile authorization controls this car is voluntarily calculated, realizes that the tracking with front truck is run.

However, in the CBTC systems shown in Fig. 1, the completion of train screening needs to be laid with substantial amounts of secondary rail in orbit Road detection device, such as remembers axis, track circuit.Railway can be divided into by secondary track detection device by several regions, Referred to as remember axis section.The position that train is reported is converted to corresponding note axis section by ZC, then detects itself and note axis section end The distance of point determines whether there is hiding train, while also needs to CI and remember axis section to the front end of note axis section where train The seizure condition of (preceding sieve) or rear end note axis section (rear sieve) is detected.

Traditional CBTC systems, ZC are required for screening the train in its compass of competency in each cycle, sort.And then Identify train position and train between corresponding relation.Transmission interaction between information due to car after car to ground, Again by the process on ground to car, cumulative errors will necessarily be in turn resulted in there are larger delay.

In the CBTC systems (as shown in Figure 3) based on truck traffic, online train sequence of the train in OC regions During, also rely in secondary track detection device.By the way that the position of train to be converted to the note axis section where it, so Tandem according to note axis section afterwards, completes the sequence of online train.

Although the information exchange delay between car ground is significantly optimized based on the train control system of truck traffic. But secondary track detection device is relied in train sequencer procedure, substantial amounts of secondary track detection device not only increases entirely The logic complexity of system, is changed so that whole if desired for the correlation between the position to train and note axis section The installation of system is difficult in maintenance, improves system cost.

With reference to shown in Fig. 4 and Fig. 5, Fig. 4 shows that the course of work of the train operation control system based on truck traffic is shown It is intended to, Fig. 5 shows the flow for the tracking operation method of the train without secondary track detection device that one embodiment of the invention provides Schematic diagram, the method for the present embodiment comprise the following steps:

401st, in train travelling process, the VOBC of the train is checked in front of current working line whether there is and is waited to establish communication The OC of connection, if in the presence of, execution step 402, otherwise, repeat step 401.

For example, VOBC, which can be checked by electronic map in front of current working line, whether there is OC.

If the 402nd, there are the OC in step 401, being sent to the OC, which includes the connection setup that current train identifies, asks Ask.

It is illustrated below for above-mentioned steps 401 and step 402:

The VOBC of train determines to whether there is the next OC adjacent with current OC in working line according to electronic map information Identification information;

If in the presence of whether the distance for determining arrival separation according to train current location is less than pre-determined distance;Described point Boundary's point is the separation of the compass of competency of current OC and next OC;

Asked if so, then being sent to OC corresponding to the identification information of next OC and including the connection setup.

403rd, after OC receives the connection setup request, the state of current compass of competency is checked.

If the 404, the OC determines that the state of current compass of competency is normal communication state, identify and correspond to the train Train sends the response for including the id information of all communication trains in the OC compasses of competency, as shown in Figure 6.

In the present embodiment, each communication train is established with OC before OC compasses of competency are entered and communicated, in the process of running, OC maintains to communicate with all communication trains operated in its compass of competency, can safeguard that portion communicates with such OC All object ID lists, as shown in following table one.

405th, VOBC identifies the id information of adjacent front truck of current train (such as according to the id information of all communication trains Shown in Fig. 7 and Fig. 8).

406th, VOBC establishes communication according to id information front truck adjacent with this of adjacent front truck, and obtains the fortune of the adjacent front truck Row status information, such as position, speed information.

407th, VOBC calculates the OC and manages according to running state information, the running state information of current train of adjacent front truck MA in the domain of area under one's jurisdiction, to realize tracking front truck operation.

Further, behind above-mentioned train operation to the compass of competency of the OC, communication is sent to the preceding OC adjacent with the OC Information is disconnected, with the communication of OC before disconnection, and the preceding OC is disconnected the relevant information of the erasing of information train (such as according to communication The id information of train, positional information etc.).

That is, when train is run in the compass of competency of the first OC, the MA of the 2nd OC compasses of competency is got, and is transported When being advanced into the compass of competency of the 2nd OC, send communication to the first OC and disconnect information.First OC and the 2nd OC are adjacent.

In a particular application, after the step 403 of the method shown in above-mentioned Fig. 4, this method is further included in following figures Unshowned step 408:

If the 408, the OC determines that the state of current compass of competency is blocked styate, to corresponding with train mark Train is sent to forbid the train to enter suppressing information for the OC compasses of competency.

That is, if train operation ahead OC compasses of competency are in blocked styate, the MA of train extends only to this At the point of interface in OC compasses of competency (the OC compasses of competency being currently located) and front OC regions.

If OC, which has fed back its compass of competency, is in blocked styate, show occur train degradation in OC compasss of competency at this time (e.g., train communication interrupts, driver has carried out degraded running), due in orbit without arrangement secondary track detection device, therefore It not can determine that the specific location of degradation train, hiding train just occur between communication train at this time, passes through management means Block to prevent the entrance of PERCOM peripheral communication train.Train can only calculate MA to two OC according to current OC feedacks at this time Separation at.

In the present embodiment, under truck traffic state, trackside is equipped with OC, different from ZC, and OC belongs to a kind of track of passive type Signalling arrangement state acquisition and control device.At present, OC maintenance lines meter shaft section takes free message, and train is run in circuit Need to keep the periodic communication with OC, so OC necessarily has all information for communicating with train.Train is entering OC administrations Being connected before region, it is necessary to be established with OC, OC feeds back the line information in its compass of competency, as shown in fig. 6, therefore, in alignment Car needs initiative recognition line status, the scope from host computer safety traffic.Train screens this information, before obtaining operation The line state information of side.The problem of so not only solving train information source, also reduces pipe by using management means Occurs the possibility for hiding train in the domain of area under one's jurisdiction.

Especially, in the case where circuit does not design axis, train must be established to communicate in inlet with OC could enter OC Compass of competency, such management means, is protected in line inlet, it is ensured that the train into OC compasses of competency is communication row Car.All trains keep communicating with OC in OC compasses of competency, and going out the train of clear OC compasses of competency needs actively to disconnect communication with OC, OC real-time servicing communication train lists, are ensured in OC regions without hiding train with this.

By the above-mentioned means, OC maintains to communicate with all trains operated in OC regions, will have in OC all logical Believe ID titles, that is, id information of object, all trains that just can be obtained current OC and communicate are arranged to the ID of these communication objects ID lists, such as following table one.

After train 1 obtains the ID lists of table one, it is to be understood that be currently operating at the communication train quantity of OC compasses of competency, root According to the ID addresses of each trains that can be looked into of the ID in table, online train identification is completed.

Online train list in one OC of table

That is, the train ID tables that train 1 is fed back according to OC, establish with other trains and communicate, obtain other trains Positional information.Communication between car and car is by the way of calling-response.Train initiates communication to the train that needs communicate please Ask, receive the train return information that the train of communication request communicates to initiation, as shown in Figure 7.

It will be appreciated that the Vehicle Controller of current train and OC communication interactions, can also obtain in the OC compasss of competency Other relevant informations, such as train quantity, train operation state.Vehicle Controller and the interaction of OC are not limited in the present embodiment Information.

OC in the above method is located at trackside and mainly realizes that the collection of trackside information and the control of trackside equipment, train are same OC obtains the line information in OC compasses of competency after establishing communication, and determines the ID letters of all trains in the OC compasss of competency Breath.The positional information and function of OC does not change in the present embodiment.This method is mainly realized by way of truck traffic The tracking operation of train, the dependence to trackside equipment is small, reduces the quantity of trackside equipment, and train is awarded from host computer movement Power has more flexible control to Train Interval, can improve the operational efficiency of train.

Illustrate, in the method shown in above-mentioned Fig. 4, front truck identification is to realize that train is followed the trail of in truck traffic system Necessary condition, train calculates tracking interval after periphery train position is identified after reaching the standard grade, can effectively protect train operation Safety, there is provided the efficiency of train operation.

For this reason, above-mentioned step 405 may specify that as follows:

In an optional implementation manner, which may include sub-step 4051 not shown in following figures to sub-step Rapid 4053:

4051st, sent out for each in all communication train id informations, the VOBC to the corresponding train of the id information Send the communication request for obtaining the train position information.

4052nd, VOBC receives the communication return information that the corresponding train of the id information is returned according to the communication request, institute Stating communication return information includes:Id information, the link positional informations of the train and the traffic direction of the train of the train.

4053rd, the identical all id informations of traffic direction are corresponded to the link positional informations of train and are ranked up by VOBC, with Determine the id information of the adjacent front truck of current train.

That is, link positional informations all on current OC compasses of competency are ranked up, to build corresponding virtual rail, According to the link positional informations of each train, the Position Approximate of corresponding each train is marked on the virtual rail of structure, into And putting in order for train is determined according to the Position Approximate of each train marked, as shown in Figure 8.

If it should be noted that there is the train that both direction is run in OC compasss of competency, at this time, due to the link of each train Positional information includes the link marks offset of the train head, the link mark offsets of the train tailstock, therefore, according to each Train head and the position relationship of the tailstock, and then can preferably determine the adjacent front truck consistent with current train traffic direction.

In general, the train that only a direction is run in OC compasss of competency, the train that few both directions are run at the same time. For this reason, following sub-step 4051a to sub-step 4053a can also be realized.

That is, in another optional implementation, above-mentioned steps 405 may include the sub-step not shown in following figures 4051a to sub-step 4053a:

4051a, for each in all communication train id informations, the VOBC is sent out to the corresponding train of the id information Send the communication request for obtaining the train position information;And

4052a, the VOBC receive the communication that the corresponding train of the id information is returned according to the communication request and reply letter Breath, the communication return information include:The id information of the train and the link positional informations of the train;

The link positional informations that all id informations are corresponded to train by 4053a, the VOBC are ranked up, to determine to work as forefront The id information of the adjacent front truck of car.

It will be appreciated that for above-mentioned all communication trains, the VOBC that each id information corresponds to communication train is being run During obtain the link positions of itself in real time according to the speed of service, run time, the cycle of operation and/or trackside equipment transponder Information;

The link positional informations include:Headstock starting point link marks and train head's phase at where train head For the offset of headstock starting point link marks;Tailstock starting point link marks and train car at where the train tailstock The offset that tail is identified relative to tailstock starting point link.

In addition, it is necessary to explanation, secondary track detection need not be laid with the CBTC systems of the present embodiment, on track and is set Standby (such as wheel counting apparatus/meter shaft), for this reason, the present embodiment carries out location determination by link modes.

In the present embodiment, division description is carried out to train operation circuit using link, division rule is:Any note axis with Between track switch, or remember between axis and note axis, or the circuit between track switch and track switch belongs to a link and (remembers that axis is secondary rail herein One kind of road detection device).By link division methods, any point on working line can use Link offsets to carry out Description, link offsets are distance of the point inside a link relative to the link starting points.For this reason, can nothing on working line Meter shaft/wheel counting apparatus need to be set, reduce cost.

In truck traffic system, it can be communicated between car and car by way of communication request and the reply that communicates.Class Like the mode of calling-response, after train sends communication request to other trains, the train for receiving communication request can be to communication The initiator of request sends communication and replys, and any communication reply will not then be carried out by not receiving the train of communication request.

In the present embodiment, the positional information that initiation train is replied that communicates is fed back to by communication train and employs link biasings The mode of shifting amount.Therefore, train judges residing link and the offset relative to link starting points according to the positional information of oneself Amount, then, searched for forward according to traffic direction before to link, and determine whether car exist, if having residing for two cars Link is identical, then is ranked up using it relative to the offset of link starting points, as shown in figure 8, along traffic direction at one There are two trains in the range of link, but two trains are different relative to the offset of link starting points, and final 1 car that is ordered as exists Afterwards, 2 cars are preceding.

And then after sequence is completed, the train of oneself forward direction on traffic direction is found, is asked to it to detailed fortune Row information, such as position, speed, calculate MA in conjunction with the operation information of this car, then follow the trail of front truck operation.So far management is passed through Means realize the train tracking operation of no secondary track detection device.

Above-mentioned front truck identification step, it is not necessary to additionally increase other equipment, on the existing system composition of truck traffic Realize identification of the train to front truck ID, i.e., train is by establishing the online train that communicates and may recognize that in the OC of front with front OC.

And then after adjacent front truck is identified, VOBC can establish communication connection by adjacent front truck with what is identified, for obtaining Take the running state information of adjacent front truck.Thus, train has Train Interval from host computer mobile authorization more flexible Control, can improve the operational efficiency of train.

Secondary track detection device is removed in the above method, once train degrades, then cannot detect the specific of train Position, therefore OC needs periodically to communicate with the train in its compass of competency, once the communication disruption with certain train, then seal OC compasses of competency are locked, and notify remaining communication train Real-time Emergency to brake, and refuses more trains and enters one's respective area, use this Kind management means can prevent from causing danger hiding train because occurring in compass of competency.

In addition, sorting in train, during identifying front truck, the train in the range of front communication OC need to be only considered, without Need the information of all fronts train, therefore the traffic has and significantly reduces, and communication efficiency is significantly improved.

Further, the present embodiment adds the sort method of offset using link, can be set departing from secondary track detection On the premise of standby quickly before identification to following train, it is not necessary to realize LINK and remember the conversion between axis section, simplify Logic complexity.
