Interlocking turnout mutual switching system at subway tie line

Abstract

The invention provides an interlocking turnout mutual switching system at a subway tie line. The system comprises a mutual switching circuit, the mutual switching circuit comprises a first loop and asecond loop which are connected in parallel, and when a subway tie line interlocking turnout is in a positioning and locking state, the first loop is switched on, and the second loop is switched off;when the interlocking turnout at the subway tie line is not indicated, the first loop is disconnected, at the moment, after mutual confirmation of two line dispatchers, a turnout fault bypass button arranged on the second loop is pressed, and the second loop is connected; and when the interlocking turnout at the subway tie line indicates recovery, the second loop is automatically disconnected. Theinterlocking turnout mutual switching system is reasonable in structure, ingenious in design and remarkable in effect; and when the interlocking turnout on any side of the tie line is lost, the mutual switching circuit is adopted, and uninterrupted operation of the other line can be achieved on the premise that driving safety is guaranteed.

Description

technical field [0001] The invention relates to the field of urban rail transit signal systems, in particular to an interlocking switch switching system at a subway tie line. Background technique [0002] Since the connecting line of the subway is usually designed as a crossing line, in order to avoid the risk of side collision between the straight train on the main line and the train on the adjacent line, the interlocking of the main line usually selects the connecting switch of the adjacent line as the side inspection condition. However, once the contact switch of the adjacent line is lost, the normal operation of the two lines will be interrupted at the same time. [0003] In order to solve the problem that the operation of both lines will be forced to be interrupted when a switch on one side loses its meter, this patent has invented a safe mutual switching circuit for a switch on one side, which is highly reliable and easy to implement. [0004] The utility model with t...
