Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0043] figure 2 It shows the flow of an embodiment of the security processing method of level conversion of the present invention. See figure 2 , the implementation steps of the security processing method in this embodiment are as follows.

[0044] Step S21: Interlocking judges whether the block partition is free, and if it is free, proceed to step S22.

[0045] Such as Figure 3A and 3B As shown, the distance between the transponder sending P90 information and the signal in front is less than the minimum train length allowed on the line. There is no train between the balise and the signal machine. If the blocked area is occupied, it mea...

Abstract

The invention discloses a safety handling method and a safety handling system for level transition. The method can automatically confirm whether a front zone is free on the premise of not reducing thespeed of a train, so that the operation efficiency is ensured, and the operation safety is guaranteed. According to the technical scheme, a transponder for sending P90 information is arranged on a train operation line, and the transponder sends a level transition command and also needs to send an information packet 90 "track ahead free up to level 2 / 3 transition location" to vehicle-mounted equipment of the train; and after receiving the information packet 90, the vehicle-mounted equipment sends an information packet 9 "level 2 / 3 transition information". Compared with the prior art, the method can automatically confirm whether the front zone is free on the premise of not reducing the speed of the train, so that the operation efficiency is ensured, and the operation safety is guaranteed.

Description

technical field [0001] The present invention relates to a safe processing method and system for ETCS (European Train Control System) ground equipment processing non-E2 / 3 to E2 / 3 level transition (Level Transition). Background technique [0002] In the traditional train class conversion method, the track circuit detects that the train passes through the border nodes of CTCS-2 and CTCS-3, and the transponder receives the notification message of the train passing the border node sent by the track circuit, and sends a class conversion command to the on-board equipment, so that the train When the transition point specified in the level transition command is passed, the level transitions from C2 to C3. [0003] Such as Figure 1A and 1B As shown, the detailed description of the implementation steps of the conventional method is as follows. [0004] Step S11: In the E2 / 3 area, when the RBC (Radio Block Center, Radio Block Center) receives the train position in LS, OS, SR, SB, and...
