Also should reset simultaneously.So, subway train is continued as new time of running table using table 3 to dispatch, just can be accumulated by before
Error concealment.
The scheduling process to subway train is illustrated by taking the time of running table of table 2 as an example.
When subway train runs according to the time of running table, such as it is 08 in current time T:00:When 47.9, detect ground
The distance travelled of iron train is SD, it is S by subway train current driving mileageDCarried out one by one with benchmark mileage in time of running table
Compare, it is S to find with the immediate benchmark mileage of current subway train driving mileagen, obtain the corresponding base of benchmark mileage
T between punctualDIt is 08:00:47.59.It should be noted that the distance travelled of the subway train under current time, may be in operation
Benchmark mileage information essentially equal therewith can be found in timetable.Cannot be operationally but in most cases, be
Found in quarter table with subway train current driving mileage corresponding benchmark mileage information completely, now just retouched more than
State, searched and the immediate benchmark mileage of current time subway train distance travelled from time of running table, it is believed that it is exactly
The current driving mileage of subway train.Compare the distance travelled S of the subway train under current time T and current timeDIt is corresponding
Reference instant TD：T≠TD, now need within the time of regulation, make the actual present bit at the current time of subway train
Put, with time of running table in current time corresponding to reference position coincide.The time of regulation described herein is this
Time adjustment threshold value T described in embodimentH.Chosen according to actual conditions, time adjustment threshold value can select to be 1S,
2S, 5 seconds etc..Select the time adjust threshold value when to consider ensure subway train both distance travelled as early as possible with time of running table in
The benchmark mileage of regulation overlaps, but to consider the size of present deviation value simultaneously, the time adjustment threshold value when deviation is larger
Larger value can be selected, suitably can also be adjusted into threshold value the time when deviation is smaller reduces.
In order that the above-mentioned situation described in the present embodiment becomes apparent from, illustrated with reference to Fig. 5 and Fig. 6, Fig. 5 and Tu
Rightmost side arrow represents travel direction in 6.
As shown in figure 5, each puts the position where subway train in the time for representing 0.1 second, the position is by mileage
Count to represent.The corresponding benchmark mileages of current time T are set as SI.Actual subway train distance travelled under current time T
Benchmark mileage corresponding in table at run time is SD.Current time T is plus time adjustment threshold value THIt is right in table at run time
The benchmark mileage answered is SH.Obviously, in the case of as shown in Figure 5, the benchmark corresponding to current time T subway train physical location
Mileage answers corresponding benchmark mileage advanced than current time in timetable.Assuming that requiring that subway train ensures its row after 0.6S
Sail position to be overlapped with the traveling-position in time of running table, then need subway train in time THIt is interior from benchmark mileage be SDTraveling
It is S to benchmark mileageH, i.e. the mileage of its traveling is SH-SD.Therefore, the travel speed required for subway train is VT=(SH-
SD)/TH。
Situation shown in Fig. 6 is with situation shown in Fig. 5 conversely, being the situation of the delayed traveling of subway train.But can from figure
To find out, if want subway train the time adjustment threshold value after overlapped with time of running table, the travel speed required for it according to
It is so VT=(SH-SD)/TH。
And once the traveling-position of subway train can overlap to the corresponding traveling-position recorded in time of running table, then may be used
To point out to make subway train be travelled according to the reference speed corresponding to next reference instant.In the manner described above, drive
Member can be known under any circumstance be travelled with which kind of speed.So as to ensure subway train it is real according to operation when
Quarter, table precisely ran.
It is aobvious using the information being arranged on subway train in step S45, S46 as the preferred scheme of the present embodiment
The mode of display screen display word is pointed out driver.
It is further preferred that in step S45, S46, language is played using the Audio Players being arranged on subway train
The mode of sound is pointed out driver.

The presentation of information board that arrives at a station is provided with subway entrance, can show the accurate arrival time of the subway train that will be entered the station with
Prompting is entered the station passenger.Therefore passenger in subway station entrance it is known that the subway train in-track platform oneself currently to be taken
The moment TQ for being accurate to the second, system also shows the required time TZ, current time TQ-T that normally walked from entrance to platform
During >=TZ, presentation of information of arriving at a station board display normal speed walking to platform, explanation normal speed can catch up with the ground to be taken
Iron train, on the contrary display negative is accomplished by accelerating the pursuit of walking paces or waits next subway train, is what is made up for lost time
Passenger provides great convenience.
Such scheme, when the benchmark mileage corresponding to current time in current mileage and the time of running table of subway train not
During coincidence, i.e., lag or lead when, driver can be pointed out within the predetermined time to ensure and transport with which kind of speed traveling
Row timetable benchmark mileage overlaps.And the current mileage for working as subway train overlaps with benchmark mileage specified in time of running table
Afterwards, it is also possible to point out driver's future to continue to keep coincidence status, it is necessary to be travelled with which kind of speed.Using upper in the present invention
The scheme of stating ensure that subway train really realizes being accurate to according to timetable set in advance the traveling of second.
In addition, using the original position of each block section as the starting point being scheduled to subway train, one in such scheme
When denier receives responder coding and changes, then by time of running table with responder coding Ci+1The corresponding base of original position
Quasi- mileage Si+1It is modified to 0 and benchmark mileage number thereafter is subtracted into Si+1, while the distance travelled of subway train is reset, by
This can be prevented by the mileage error that subway train long distance running is accumulated, because the distance of each track subregion is shorter,
The distance travelled of interval interior train does not have too big error herein, can so effectively reduce cumulative errors, it is ensured that train is entered
Row is accurate to the scheduling of second also for the subway entrance issue accurate station-arrival of subway train moment lays a good foundation.
