- the lengths of the speed sections are different from each other.
- the run time and minute of the run curves C3 1 , C3 2 , ..., C3 n in the low speed mode differ depending on the length of the constant velocity section.
- the run curves for various traveling times are prepared by adjusting the length of the constant velocity section in the run curve in the low speed mode.
- the normal mode run curve C1 and the low speed mode run curve C3 1 , C3 2 , ..., C3 n shown in FIG. 18 have different speeds in the constant velocity section, but the section where full acceleration is performed from the departure station to the position P10.
- the acceleration section is also included as the recommended section for switching the first run curve. Therefore, when switching from any of the low-speed run curves C3 1 , C3 2 , ..., C3 n to the normal mode run curve C1 on trains 2C 1 to 2 cm , the arrival target time is updated to the first run curve switching recommended section. If possible, acceleration / deceleration due to switching of the run curve does not occur.
- the lengths of the constant velocity sections are different from those of the low-speed mode run curves C3 1 , C3 2 , ..., C3 n shown in FIG. 18, it is recommended to switch the section from the departure station to the position P11. It has both as a section. Therefore, when switching from one of the low-speed run curves C3 1 , C3 2 , ..., C3 n to the other run curve on trains 2C 1 to 2 cm , the arrival target is the second run curve switching recommended section. If the time can be updated, acceleration / deceleration due to the change of the run curve does not occur, so that the increase in power consumption due to the acceleration / deceleration due to the change of the run curve does not occur.
- the processing unit 54 of the on-board device 50A calculates the second arrival target time using the minimum headway included in the minimum headway information 33, as in the processing unit 54 of the on-board device 50.
- the headway changes depending on the station approach speed.
- the following train 2B can enter the next station, but if the approach speed of the following train 2B to the next station is extremely low, it takes time to arrive at the next station. It takes too much and the minimum headway is greatly extended. Multiple run curves include those with a large minimum headway and those with a small minimum headway.
- the calculation unit 24 of the operation management device 10 calculates the arrival target time, as shown in FIG. 3, the minimum headway set only one for each station is used. Therefore, there may be a large difference between the minimum headway used when calculating the arrival target time and the minimum headway of the selected run curve, and highly accurate operation may not be realized. Therefore, in the on-board device 50A, a plurality of run curves C1, C2, C3 1 , C3 2 , ..., C3 n shown in FIG. 19 are stored in the storage unit so that a large difference does not appear in the minimum headway for each run curve. It can also be stored in 53A.
- the sections from the departure station to the position P20 have the same speed characteristics, and such sections are recommended run curve switching sections. Set. If the arrival target time can be updated in the recommended run curve switching section in the operation management device 10, acceleration / deceleration due to the run curve switching does not occur in the trains 2A 1 to 2 Am.
- the station approach section which is the approach section to arrive at the station, so that the approach speed to the arrival station does not change significantly.
- the speed characteristics have been adjusted.
- the speed of the train 2 in the station approach section is the station approach speed of the run curve where the minimum operation time interval indicating the departure / arrival interval is the smallest.
- the run curves C1, C2, C3 1 , C3 2 , ..., C3n shown in FIG. 19 are shown in FIGS. Compared to the run curves C1, C2, C3 1 , C3 2 , ..., C3 n , the difference in the minimum operating time interval between the two can be reduced.
- the speed in the station approach section in the run curve having a long running time is a constant speed.
- the run curves C1, C2, C3 1 , C3 2 , ..., C3 n may have the same speed in the station approach section. In this case, in the railway system 100A, the difference in the minimum headways between the two can be eliminated.
- the number of run curves C1, C2, C3 1 , C3 2 , ..., C3 n is the minimum operation time in which the speed indicates the departure / arrival interval to the arrival station in the approach section to the next station. It is set within a predetermined range with the station approach speed of the run curve where the distance is the smallest as near the center. As a result, in the railway system 100A, a large difference does not occur in the minimum headway of the run curve selected by the train 2C, and it is possible to support highly accurate operation.
- the configuration shown in the above embodiments is an example, and can be combined with another known technique, can be combined with each other, and does not deviate from the gist. It is also possible to omit or change a part of the configuration.
