Abstract

PURPOSE:To enable the control of a train interval nearly as in the case of motion and blocking to be realized via the addition of only two or three track lines per station by applying several blocking divisions only to a platform requiring detailed information on the trailing position of a train. CONSTITUTION:Blocking boundaries are set, for example, at K0 to K5. Namely, the length (K0 to K3) of a platform S is divided into small portions, while other track lines are kept at currently blocked length. A signal for the blocking division length L2 (K4 to K5) where a leading end is existing, and a distance L1 from the boundary K4 forward of a blocking point to the rear boundary K1 of a blocking point for a leading train T1, or a total thereof (L1 + L2) is transmitted from a ground station to a trailing train T2. The train T2 detects the travel thereof over a distance L3 within the blocking division (K4 to K5) with a distance integrator installed thereon, calculates a distance up to the blocking boundary K1 where the leading train T1 is existing, and identifies the distance as L4. As a result, a speed pattern P is generated and train speed is controlled on the basis of the aforesaid pattern.

（従来の技術） 従来は列車の位置検知や速度指示を行うために。(Conventional technology) Conventionally, it was used to detect the position of trains and give speed instructions.

レールを数十メートルから数百メートルに区切り。Divide the rail into sections ranging from tens of meters to hundreds of meters.

この区間（閉そく区間）における列車の有無により列車
の位置を検知し、速度指示を行っていた。The position of the train was detected based on the presence or absence of a train in this section (block section), and speed instructions were given.

電気回路の一部に使った軌道回路が広く使われている。Therefore, in order to finely control trains and further shorten train intervals, it is necessary to create a block from the position where the following train approaches while the preceding train is stopped at the platform to the position where the preceding train advances by the time the following train stops at the platform. It was necessary to divide the section into smaller sections. Track circuits that use rails as part of the electrical circuit are widely used for position detection in this section.

知する方式を採用する。For other sections, the current block is used as is, and the distance to the block boundary where the preceding train is located is continuously transmitted from the ground to the train, and the following train is within the distance received by the on-board distance integrator. The system uses a method that continuously detects the distance to the block boundary where the preceding train is located by calculating how far the train has entered the block boundary.

0 train T2, which transmits the distance Ll to l, or the sum L1+L2, is L of the block section (K4 to 5)
