Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation control system for controlling the operation of trains, especially on a high-density railway line in a city.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing a conventional train operation control system disclosed in, for example, Japanese Patent Publication No. 61-54623. In the figure, A and B are trains, 30 is a station, 31
Is ATC fixed block signal equipment installed along the track, 3
Reference numeral 2 is a transmission facility for transmitting a command from the ground to a train installed in the station 30, and 33 is a central operation control facility installed on the ground side. The train is equipped with ATC and ATO control devices. In this operation control system, the positions and train numbers of the trains A and B can be known by the central operation control equipment 33 on the ground side receiving the information that the trains A and B have changed the track circuit section of the ATC blockage equipment 31. it can. Further, the central operation control facility 33 internally collates the planned timetable with the position of the train, controls the speed of the train group according to the deviation from the plan, and corrects this deviation. In this speed control, when trains A and B arrive at the station 30, the speed command V _P of the central operation control equipment 33 is transmitted to the trains A and B via the transmission equipment 32 so that the on-board ATO control device transfers to the next station. It is carried out during driving. The speed control of the train is further controlled by the ATC security facility for safety. That is, when the succeeding train approaches the preceding train, the blockage facility 31 detects this and gives a low-level ATC signal to the track circuit behind the preceding train, and the on-board ATC control device detects this to limit the speed of the train. If is exceeded, the brake system on the train is activated to keep the train speed at a safe speed. In this operation control system, the position / speed program is given to the train at the previous station before the train departs for the next station.

[0003]

Since the conventional train operation control system is configured as described above, after the departure time and the inter-station traveling speed are determined at the time of departure from the station, the situation changes such as the delay of the preceding train increasing. Even if the train stops at the next station, there is no countermeasure, and you must continue to run at normal speed and stop and wait until the preceding train departs immediately before the next station due to security devices such as traffic lights. Therefore, when stopping between stations in this way, it takes a long time to depart and accelerate again, and there is a problem in that the train operation is disturbed on a high-density service route.

The present invention has been made to solve the above problems, and when a preceding train is stopped at a station, the train is decelerated in advance to prevent the stop between stations. The objective is to obtain a train operation control system that can quickly respond to changes in the situation of the preceding train, etc. even between stations that run with an optimal speed pattern according to the departure of the preceding train, and can always ensure optimal train travel. And

Next, the operation of FIG. 1 will be described with reference to FIG. Now, in FIG. 2A, it is assumed that the train 1 is running and the train 2 leaves the station 4. In the running train 1, the train state detection device 14 outputs the train state (for example, train position, speed, door open / closed state) based on the output of the speed control device 13 that controls the drive unit (not shown) of the train 1. Etc.) is detected, and the detection output is supplied to and stored in the train state storage device 15. At the timing as shown in FIG. 2 (a), for example, regarding the departure time and the traveling speed which are determined to be optimal from the distance between the trains before and after, the speed curve (speed A command targeting the (pattern) is given from the central control device 01 to the train 2 via the ground-side transmission device 21T.
