Abstract
The invention discloses an ordering method and an identifying number tracking method of a train in a fixed block mode. The ordering method of the train comprises the steps that as a train head enters a logic zone, whether a train queue exists in the logic zone or not is detected; if the train queue does not exist in the logic zone, a new train queue is built and a train set number is added to the head of the train queue; if the train queue exists in the logic zone, the train set number is added to the tail of the train queue; and when the train head enters a next logic zone, the train set number and all the former train set numbers are deleted from the train queue. The identifying number tracking method of the train comprises the steps that when a next axle-counting zone of the train is occupied by other identifying numbers, a train identifying number stays in the current axle-counting zone; if the next axle-counting zone meets a stepping condition, whether the train is at the head of the train queue is judged; and if the train is at the head of the train queue, identifying number stepping is conducted. With the adoption of the ordering method and the identifying number tracking method, when the fixed blocking trains are positioned in the same axle-counting zone, no interference of a dispatcher is needed; and when the train is started, the identifying number can be tracked automatically.

S102-2, add the car group number of described train the tail of the queue of described train formation to, then enter step S103.
Preferably, also comprise step after the step S103:
In S104, the described logic block of detection whether car is arranged, if not, then delete described train formation.
Based on above-mentioned train sort method, the present invention has proposed a kind of train identifier method for tracing simultaneously, and as shown in Figure 2, described train identifier method for tracing may further comprise the steps:
S201, according to the current meter shaft section at train place, obtain next meter shaft section of described train, and detect the pressure condition that accounts for of described next meter shaft section, if the occupied pressure of described next meter shaft section then enters step S202;
Whether S202, described next the meter shaft section of detection are taken by other train identifiers, if then described train does not carry out stepping, the identifier of described train rests on described current meter shaft section, if not, then enters step S203;
The train formation of all logic blocks in S203, described next the meter shaft section of traversal and the described current meter shaft section, whether the car group number of judging described train is at team's head of all train formations, if not, then described train does not carry out stepping, the identifier of described train rests on described current meter shaft section, if then described train carries out stepping, the identifier of described train steps to described next meter shaft section.
Preferably, also comprise step after the step S203:
The meter shaft section that does not have occupied pressure in S204, the tabulation of deletion meter shaft section.
As previously mentioned, under normal circumstances, multiple row fixed blocking train can not appear in same meter shaft section.But under some abnormal condition, might occur:
(1) multiple row CBTC car is arranged in same meter shaft section, the front truck degradation will cause rear car degradation;
(2) car advances rashly behind the non-CBTC, pours non-CBTC front truck place route.
Solve the first abnormal condition, the multiple row CBTC car in the same meter shaft section is evacuated, and the every train identifier forward condition of stepping is: this car is the front truck in the current meter shaft section.Only have when satisfying this condition, follow the trail of logic according to the CBTC car, nature can be realized the automatic tracing of the every train identifier in the evacuation process.
When multiple row CBTC car in same meter shaft section, judge certain train wherein whether the method for front truck be: for each meter shaft section that has car to enter, to the train processing of sorting; Because the meter shaft section is divided into one or more logic blocks, therefore each logic block that has car to enter is arranged a train formation.According to headstock identifier stepping information, record the train consist number that each row enters this logic block.When train head's identifier is jumped out this logic block, need to delete this car car group number from queue heads, thereby can safeguard that each has car to enter train order in the logic block.
The below processes the ordering of train and is illustrated.
Owing to be due to the CBTC car is demoted, when carrying out so the tracking of CBTC car (the logic block position data of reporting according to zone controller ZC is fully carried out identifier and followed the trail of), just to the train processing of sorting, each logic block is arranged a train formation, when reporting the generation stepping of CBTC car headstock position, such as the variation of Fig. 3 to Fig. 4, CBTC car 2 headstock logic blocks step to b from a, at first, process the train formation of original CBTC car 2 headstock logic block a, in the train formation of logic block a deletion CBTC car 2 and before all car group numbers, then the front truck of a formation is CBTC car 3 among Fig. 4; Simultaneously, also to process the train formation of CBTC car 2 current headstock logic block b, if logic block b formation exists, add at b formation tail of the queue the car group number of CBTC car 2, if there is no, need the train formation of newly-built logic block b and the car group number of adding CBTC car 2 at tail of the queue.For the train formation of logic block, when first car enters, need the train formation of newly-built this logic block, the train formation of when last car leaves, deleting this logic block.When CBTC car 1 entered logic block b for the first time, the train formation of newly-built logic block b when the 3 generation steppings of CBTC car and a formation do not have other car to enter, at this moment will be deleted whole a formation such as Fig. 4 such as Fig. 3.
How following casehistory finds out front truck.
CBTC car in Fig. 4 is demoted, then situation shown in Figure 5 can occur, the non-CBTC car of multiple row is at same meter shaft section, when next meter shaft section B accounts for pressure, non-which car of CBTC car of 3 row of determining meter shaft section A carries out stepping, just need to search front truck according to above-mentioned ordering processing.As shown in Figure 5, according to current of traffic, travel through successively all logic block formations that next meter shaft section B of train and current meter shaft section A comprise, the order that namely travels through logic block is d, c, b, a, logic block d and c are current not to have train to enter, be that the train formation does not exist, then travel through in order logic block b formation, logic block b formation train sequentially is non-CBTC car 1, non-CBTC car 2, therefore can get access to apart from the front truck of next physical zone B is non-CBTC car 1, is non-CBTC car 1 so need the train of stepping.
Solve the second abnormal condition, when rear car advances rashly when pouring front truck place meter shaft section, because next meter shaft section of rear car is taken by the front truck identifier, the car identifier can not emit and then stepping with train after the institute, the identifier of rear car still rests on a meter shaft section, when the front truck identifier account for front truck press leave after, rear car identifier accounts for pressure situation automatic tracing according to next meter shaft section and comes.
As shown in Figure 6, when advancing rashly, non-CBTC car 1 pours meter shaft section C, although train 1 is judged next meter shaft section C and has been in seizure condition, because meter shaft section C is taken by the identifier of non-CBTC car 2, so the identifier of train 1 can not step to meter shaft section C, still stays the meter shaft section B, D accounts for pressure when the meter shaft section, train 2 steps to meter shaft section D with accounting for to press, and then the identifier of train 1 steps to meter shaft section C.
The above only is preferred implementation of the present invention; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
