Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
Train sort method under the fixed blocking pattern that the present invention proposes, as it is shown in figure 1, comprise the following steps:
S101, when train head enter a certain logic block time, detect whether described logic block exists the train queue of correspondence, if not, then set up train queue for described logic block, and the car group number of described train is added to team's head of described train queue, subsequently into step S103, if so, then enter step S102；

S103, when described train head enters next logic block, the car group number of described train and all car group numbers before thereof are deleted from described train queue.
Preferably, step S102 farther includes:
S102-1, detect in the car group number whether Already in described train queue of described train, be if so, then directly entered step S103, if it is not, then enter step S102-2；
S102-2, the car group number of described train is added the tail of the queue of described train queue to, subsequently into step S103.
Preferably, further comprise the steps of: after step S103
S104, detect in described logic block whether have car, if it is not, then delete described train queue.
Based on above-mentioned train sort method, the present invention proposes a kind of train identifier method for tracing simultaneously, as in figure 2 it is shown, described train identifier method for tracing comprises the following steps:
S201, current meter shaft section according to train place, obtain next meter shaft section of described train, and detect next meter shaft section described account for pressure condition, if next occupied pressure of meter shaft section described, then enter step S202；
Whether S202, detection next meter shaft section described are taken by other train identifiers, and if so, then described train does not carry out stepping, and the identifier of described train rests on described current meter shaft section, if it is not, then enter step S203；
The train queue of all logic blocks in S203, traversal next meter shaft section described and described current meter shaft section, judge that the car group number of described train is whether at team's head of all train queues, if not, then described train does not carry out stepping, the identifier of described train rests on described current meter shaft section, if so, then described train carries out stepping, and the identifier of described train steps to next meter shaft section described.
Preferably, further comprise the steps of: after step S203
S204, deletion meter shaft section list do not have the meter shaft section of occupied pressure.
As it was previously stated, under normal circumstances, multiple row fixed blocking train is not had in same meter shaft section.But under some abnormal conditions, it is possible to occur:
(1) having multiple row CBTC car in same meter shaft section, front truck is demoted, and will result in rear car degradation；
(2) non-CBTC rear car advances rashly, and pours non-CBTC front truck place route.
Solving the first abnormal conditions, multiple row CBTC car in same meter shaft section is evacuated, and every train identifier can the condition of stepping forward be: this car is the most front truck in current meter shaft section.When only meeting this condition, following the trail of logic according to CBTC car, nature can realize the automatic tracing of the every train identifier in evacuation process.
When multiple row CBTC car is in same meter shaft section, it is judged that wherein whether be certain train if being the method for most front truck: for each meter shaft section having car to enter, is ranked up train processing；Owing to meter shaft section is divided into one or more logic block, therefore each logic block having car to enter is arranged a train queue.According to headstock identifier stepping information, record every string and enter the train car group number of this logic block.When train head's identifier jumps out this logic block, it is necessary to delete this car car group number from queue heads, such that it is able to safeguard each train order having in car entrance logic block.
Below the sequence of train is processed and be illustrated.
Due to be CBTC car degradation caused by, so carry out (following the trail of completely) when CBTC car is followed the trail of according to the zone controller ZC logic block position data number of being identified reported, just it is ranked up train processing, each logic block is arranged a train queue, when reporting CBTC car headstock position and stepping occurring, change such as Fig. 3 to Fig. 4, CBTC car 2 headstock logic block steps to b from a, first, process the train queue of original CBTC car 2 headstock logic block a, in the train queue of logic block a delete CBTC car 2 and before all car group numbers, then in Fig. 4, the most front truck of a queue is CBTC car 3；Simultaneously, also to process the train queue of the current headstock logic block b of CBTC car 2, if logic block b queue exists, the car group number of CBTC car 2 will be added at b queue tail of the queue, if there is no, it is necessary to the train queue of newly-built logic block b also adds the car group number of CBTC car 2 at tail of the queue.For the train queue of logic block, when first car enters, it is necessary to the train queue of this logic block newly-built, delete the train queue of this logic block when last car leaves.If Fig. 3 is when CBTC car 1 first time enters logic block b, the train queue of newly-built logic block b, if Fig. 4 is when CBTC car 3 occurs stepping and a queue not to have other car to enter, at this moment to delete whole a queue.
It is exemplified below and how to find out most front truck.
When the CBTC car in Fig. 4 is demoted, then there will be the situation shown in Fig. 5, multiple row non-CBTC car is at same meter shaft section, when next meter shaft section B accounts for pressure, determine the 3 of meter shaft section A arranges non-which cars of CBTC car and carries out stepping, it is necessary to process according to above-mentioned sequence and make a look up most front truck.As shown in Figure 5, according to current of traffic, all logic block queues that traversal train next meter shaft section B and current meter shaft section A comprises successively, namely the order traveling through logic block is d, c, b, a, logic block d and c enters currently without train, namely train queue is absent from, then traversal logic block b queue in order, logic block b queue train order is non-CBTC car 1, non-CBTC car 2, therefore can get the most front truck from next physical zone B is non-CBTC car 1, so the train needing stepping is non-CBTC car 1.
Solve the second abnormal conditions, when rear car advances rashly and pours front truck place meter shaft section, owing to next meter shaft section of rear car is taken by front truck identifier, so rear car identifier will not emit with train and then stepping, the identifier of rear car remains in a meter shaft section, current vehicle identifier accounts for after pressure leaves with front truck, and rear car identifier accounts for pressure situation automatic tracing according to next meter shaft section and comes.
As shown in Figure 6, meter shaft section C is poured when non-CBTC car 1 advances rashly, although train 1 judges that next meter shaft section C is already at seizure condition, owing to meter shaft section C is taken by the identifier of non-CBTC car 2, so the identifier of train 1 will not step to meter shaft section C, still remain in meter shaft section B, when meter shaft section D accounts for pressure, train 2 steps to meter shaft section D with accounting for pressure, and then the identifier of train 1 steps to meter shaft section C.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for the person of ordinary skill of the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and replacement, these improve and replace and also should be regarded as protection scope of the present invention.
