Problems solved by technology

[0003] The existing interlocking equipment protects the turnout area with the approach as a unit, requiring the main turnout and the side protection turnout on the approach to move into place and lock successfully before allowing the train to enter the turnout area protected by the interlock approach; and Existing interlocking equipment executes occupancy locking and section locking on the turnout in units of sections, that is, the access permission of the turnout area is given in units of the entire interlocking route, and the movement permission of the turnout is given in units of Sections are judged in units. This method is applicable to train control systems that use axle counting equipment or track circuits as train positioning equipment and non-moving blockages, but it is serious for train control systems that use accurate train positioning and moving blockages. Limits operational and turn-back capabilities of the train control system

[0093] In the first embodiment, the present invention provides a rail transit train approach and switch control method, including the following steps:

[0094] S1, read the existing train route and switch control configuration;

[0095] S2. Determine the switch control mode according to the read train switch control mode and train control mode;

[0096] S3, judging whether the state of the turnout satisfies the train running according to the confirmed turnout control mode; if it is satisfied, then execute the judgment of the lateral protection mode;

[0097] S4, determine the lateral protection method according to the read train lateral protection method and the train control mode;

[0098]S5, judging whether the lateral protection condition is satisfied according to the confirmed lateral protection method, the movement of the lateral switch and whether there is a train on the non-traveling path track in the lateral protection area;

[0099] S6, determine whether the turnout...

[0102] Second embodiment, such as image 3 As shown, the present invention provides a rail transit train approach and switch control method, including:

[0103] Step S1 reads the configuration to obtain the configuration of the switch control mode, the configuration of the lateral protection mode and the configuration of the switch movement judgment mode.

[0104] Step S2 determines the switch control mode according to the configuration of the switch control mode and the control mode of the train. Step S2.1 Check whether the switch control mode is configured as automatic control, if yes, go to step S2.2, otherwise, go to step S2.3; step S2.2 judge whether the train is a moving block train; if yes, then judge The control mode of the turnout is individual control, otherwise, it is determined that the control mode of the turnout is the overall control; step S2.3 checks whether the control mode of the turnout is configured as the overall control, if yes, it is determined that the...

[0117] In the third embodiment, the present invention provides a rail transit train approach and turnout control module that is used in a train control system and can be realized by means of computer programming techniques, including:

[0118] A communication unit, which is used to read existing train routes and switch control configurations;

[0119] A turnout control unit, which is used to determine the turnout control according to the read train turnout control mode and train control mode;

[0120] The first judging unit is used to judge whether the state of the turnout satisfies the train running according to the confirmed turnout control mode; if it is satisfied, then execute the judgment of the lateral protection mode;

[0121] A side protection control unit, which is used to determine the side protection mode according to the read train side protection mode and train control mode;

[0122] The second judging unit is used to judge whether the lateral protection conditio...

Abstract

The invention discloses a rail transit train route and switch control method, comprising: reading the existing train route and switch control configuration; determining the switch control mode according to the train switch control mode and the train control mode; judging the switch according to the track switch control mode Whether the state satisfies the requirement of train running; if it is satisfied, judge the lateral protection mode; determine the lateral protection mode according to the read train lateral protection mode and train control mode; determine the lateral protection mode according to the confirmed lateral protection mode, lateral switch movement and Whether there is a train on the non-walking path track in the lateral protection area to judge whether the lateral protection condition is met; determine whether the switch is movable according to the read judgment method of the movable switch and whether the train is accurately positioned; if it is determined that the switch is movable, it is the subsequent train Move the switch; otherwise, re-judge whether the switch is movable. The invention also discloses a rail transit train approach and switch control system. The invention can realize the dynamic control of the route and the turnout during the running process of the rail transit train.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a method for controlling rail train approach and turnout based on a train control system. The invention is also a module used for rail train approach and switch control based on the train control system. Background technique [0002] At present, whether it is the communication-based train control system (CBTC, Communication Based Train Control) adopted by urban rail transit, the CTCS train control system (Chinese Train Control System) adopted by the national railway, or the old signal system without ATP protection, all are based on The trackside interlocking equipment is built as the core, that is, with the development and innovation of technology, new equipment and functions are continuously added to the train control system, but as the interlocking equipment of the core equipment of the signaling system, its processing The function of roads and switches has not changed substantiall...
