Problems solved by technology

[0003] In the prior art, when the all-electronic execution unit or the relay circuit fails, the turnout will not rotate properly or the information of the turnout will not be collected correctly.
If the fault occurs at the switchback station, the train will not be able to pass because the turnout cannot be rotated in place or cannot give a correct indication, which will seriously affect the operation
[0004] In addition, during the reconstruction of the old line, when the old project uses the relay circuit to control the turnout, and the full electronic execution unit is used to control the turnout after the transformation, the outdoor turnout control right needs to be frequently switched between the old and new systems during commissioning
The process of switching control rights of turnouts and modifying wiring is complex, time-consuming and error-prone
Difficult to debug during retrofit

Abstract

The invention discloses a turnout control switching system of a full-electronic execution unit and a relay circuit, which comprises the full-electronic execution unit, a relay turnout control circuit and an interlocking upper computer for controlling the full-electronic execution unit and the relay turnout control circuit, and switching of the turnout control right between the full-electronic execution unit and the relay turnout control circuit is realized through the interlocking upper computer. By adopting the turnout control switching system, the redundancy of the turnout controlled by the full-electronic execution unit and the relay circuit is realized, the availability of the turnout control system is improved, and the influence on operation when a single system fails is reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a signal control system. Background technique [0002] Turnout control in urban rail transit signal control system is an important basis for train control. The existing switch control system is a single all-electronic execution unit switch control mode or a relay circuit switch control mode. The interlocking system sends the switch control command to the fully electronic switch execution unit (or the relay circuit switch control system). After receiving the command, the switch control system controls the rotation of the switch machine and turns the switch to the requested position. After the turnout turns in place, the turnout control system collects the position information of the turnout and sends it to the interlocking system. [0003] In the prior art, when the all-electronic execution unit or the relay circuit fails, the turnout will not rotate properly or...
