Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a train operation control device, and particularly to a device that performs operation control suitable for energy-saving train operation.

[Background of the invention]

As described in Japanese Patent Laid-Open No. 55-160661, the control method for train groups in conventional operation control devices is such that when a train is delayed for more than a certain amount of time, the train is made to run in the shortest possible time. He was giving me a pattern. However, while the conventional system can quickly recover from delays, it has had the problem of significantly increasing power consumption due to the reduction in operating time.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a train operation control device that provides the most energy-saving operation method for restoring the timetable when a train is delayed or arrives early.

[Summary of the invention]

Generally, in a railway system, as shown in Figure 2, stations 11~
Multiple trains run back and forth between stations 1n and 1n.

Here, a timetable is created to obtain the desired transportation capacity, and this timetable can be approximately determined based on the travel time of one train from the terminal station 11 to the terminal station 1n and the transportation capacity of one train.

Here, the numerator t when traveling from the terminal station 11 to the terminal station 1n
otal is expressed as the sum of the running time numerator i between each station, but the running time between each station is usually calculated with a margin of several percent compared to the running time obtained when traveling between stations at maximum speed. The vehicle is set to a certain value, and the vehicle is operated at nine speeds depending on the travel time.

If a train is delayed, the train runs between stations at maximum speed to shorten the travel time to recover from the delay.

Here, it is known that when comparing the power consumption of a train when the train is operated over the same distance at different running times, the curve shown in FIG. 3 is generally drawn. This means that if you drive close to the upper limit of vehicle performance in order to shorten driving time,
Loss increases and power consumption sharply increases. Moreover, if acceleration/deceleration control is avoided as much as possible between stations and the ratio of coasting operation control is increased, the travel time between stations will be extended, but power consumption can be suppressed.

Therefore, as shown in Fig. 4, the relationship between traveling time t and power consumption P between stations i is set as p=: f 1 (t),
If the traveling time between stations i determined from the timetable is tl, it is assumed that a train entering between stations l is delayed by ΔT. Now, if we try to recover from train delays only by station distance i,
The power consumption during that time is fi (ti - Δ'I') - fi
(t i ) increases. However, if the delay of ΔT is restored evenly among, for example, six stations, it is clear from the figure that the increase in power consumption is smaller than the increase in power consumption when the delay is restored at the − station.

It is also clear that the more stations that are restored, the greater the energy saving effect will be.

In addition, when a train arrives early, the conventional system does not allow the train to depart until the departure time determined by the timetable. It is also clear that effects can be obtained.

[Embodiments of the invention]

An embodiment of the present invention will be explained below with reference to FIG.

The loop 23 installed on the platform track of the station allows
The train operation control device 21 captures the signal 5 detected by the train stop detection device 24 when the train 22 arrives at the station, compares the capture time 6 with the arrival time 7 of the train 22 on the timetable, and calculates the difference between the two.
That is, the delay time 8 of the train 22 is determined. After this, the value obtained by dividing the delay time 8 by the number of stations from the station to the terminal station is the shortened travel time between the next stations, which is 9, and the value obtained by subtracting the standard travel time between the next stations, which is 10, is the value calculated as the next station. The travel time in between is 31 minutes, and the data is transmitted to the VHF device via the data transmission section. The signal 32 transmitted to the VHF device is taken into the ATO device on the vehicle via a single immersion coaxial cable 14 laid along the line 33. A.T.
The O device follows the running time from the train operation control device 21,
The train travels between the next stations and performs the desired delay recovery.

Claims (1)

[Scope of Claims] 1. In a railway system in which a group of trains shuttles between a plurality of stations, the railway system includes a transmission control device for transmitting a running pattern between the next stations to the automatic operation control device of each train, When a delay or early arrival of the train occurs, (a) one that can shorten the time calculated by the following formula from the timetable running time between the next stations is commanded as the running pattern between the next stations. Reduced time = Delay amount for the current train schedule / Number of stations between stations to the terminal station (b) The time that can be increased by the following formula from the traveling time on the timetable between the next stations is calculated as the next station. The command is given as a running pattern between the two. The train operation control device is characterized by transmitting these control commands to the train via the transmission control device.
