Abstract
The invention discloses a switch control switching system of a full electronic execution unit and a relay circuit, which comprises the full electronic execution unit, the relay switch control circuit and an interlocking upper computer for controlling the full electronic execution unit and the relay switch control circuit, wherein the switch control right between the full electronic execution unit and the relay switch control circuit is switched by the interlocking upper computer. By adopting the technical scheme, the invention realizes the redundancy of controlling the turnout by the full-electronic execution unit and the relay circuit, improves the availability of the turnout control system and reduces the influence on operation when a single system fails.
Description
Technical Field
The invention belongs to the technical field of rail transit, and particularly relates to a signal control system.
Background
The control of the turnout in the urban rail transit signal control system is an important basis for train control. The existing turnout control system is in a single full-electronic execution unit turnout control mode or a relay circuit turnout control mode. The interlocking system sends a turnout control command to an all-electronic turnout execution unit (or a relay circuit turnout control system), and the turnout control system receives the command and then controls the turnout to rotate to a requested position. After the turnout rotates in place, the turnout control system collects turnout position information and sends the turnout position information to the interlocking system.
In the prior art, when a full-electronic execution unit or a relay circuit breaks down, the turnout cannot rotate in place or turnout indication information cannot be correctly acquired. If the fault occurs in the turning-back station, the train can not pass through the station because the turnout can not rotate in place or can not give a correct indication, and serious influence is caused to the operation.
In addition, when an old line is transformed, when an old project adopts a relay circuit to control turnouts and a full-electronic execution unit is adopted to control turnouts after transformation, the control right of the outdoor turnout needs to be frequently switched between a new system and an old system during debugging. The process of switching and modifying the distribution of the turnout control right is complex, long in time consumption and easy to make mistakes. The debugging difficulty during the transformation is very large.

Specifically, as shown in fig. 2, the switch full-electronic control first passes through the full-electronic execution unit, outputs five cables to access the control right switching circuit connection terminals, and performs parallel connection processing on full-electronic output through the connection terminals.
