Description
Technical Field
The invention relates to the technical field of rail communication, in particular to a method for controlling a tie line turnout of an interconnection CBTC system.
Background
With the rapid development of urban rail transit, communication-based train control systems (CBTC) have gained wider and wider application. With the increasing demands of sharing resources and carrying passenger cross-line networked operation of a plurality of lines, the interconnection CBTC system is becoming mature.
In the current interconnection line, the traditional mode is still adopted in the interconnection line wiring mode. As shown in fig. 1, P1 and P2 are tie switches, controlled by different line interlocks. When the train of the line A passes through the P1 location, the P2 is not automatically driven to the location for lateral protection, but the P2 is located as one of the inspection conditions for pulling the P1 to the location, and the P1 can be pulled to the location only when the P2 is located. The same applies to P1 when the train on route B passes through the location of P2. In a traditional non-interconnected circuit, without an over-the-wire train during operation, the P1 and P2 would normally be locked in place to provide side protection for trains in both circuits. When the operation is finished and the vehicle is dispatched in an overline mode, the two lines are respectively arranged in a receiving route and a departure route through manpower, and the P1 and the P2 are pulled to be in the reverse position. After the cross-line shunting is finished, the two lines are manually operated to switch the points, and the points P1 and P2 are pulled to be positioned.
However, in the interconnection project, during normal operation, trains are operated over-line, if line a has one train operated over-line, P1 and P2 are pulled to reverse, and then another train is not over-line and is positioned by P1. However, the P2 can not be automatically driven to the positioning, so that the lateral turnout prevention condition is not met, and the P1 can not be pulled to the positioning, thereby influencing the normal operation. In an interconnection line operated by crossing lines, a connecting line turnout is the same as a double-acting turnout of a main line, and a side interlocking prevention driving relation which is the same as that of the main line turnout can be formed to meet normal operation. However, the current technology cannot solve the problem because the two tie line switches belong to different interlocking device controls. How to realize that the side anti-turnout controlled by other interlocking equipment is automatically driven is the technical problem to be solved by the invention.
Disclosure of Invention
The invention aims to provide a connecting line turnout control method of an interconnection CBTC system, which realizes the automatic driving of a side-protection turnout and provides the side-impact protection of the connecting line turnout when a cross-line operation train and an in-line train run in a mixed manner.
The technical scheme for realizing the purpose is as follows:
a method for controlling a tie line turnout of an interconnection CBTC system comprises the following steps:
adding at least one positioning control relay for a side anti-turnout;
when the train of one line pulls the main turnout of the access way to be positioned through the interlocking of the line, the side turnout is automatically driven to be positioned by the interlocking of the other line through the positioning control relay.
Preferably, when a train on one line pulls the main turnout of the access way to be positioned through the interlocking of the line, the positioning control relay of the side turnout is activated, and the side turnout is automatically driven to be positioned when the interlocking of the line to which the side turnout belongs detects that the positioning control relay is activated.
Preferably, the method further comprises the following steps:
when the train of a line runs in a cross-line mode, the interlocking of the line is that the trains are arranged from a departure platform to a departure approach of a boundary, and an approach main body turnout is pulled to be in a reverse position; the interlocking of the other line is that the trains are arranged from the boundary to the receiving access of the receiving platform, and the side turnout is pulled to be in the reverse position;
when the interlocking of the other line fails, the side turnout can be manually locked in position.
Preferably, the number of the positioning control relays added for preventing the turnout on the side is two.
Preferably, two positioning operating relays are added to the access main turnout.
The invention has the beneficial effects that: the interconnection line turnout of the interconnection line is defined as a main access turnout and a side prevention turnout, and the main access turnout and the side prevention turnout are supported to be controlled by different interlocks. When the non-stop cross-line train and the operation train in the line operate in a mixed mode, the invention can automatically provide complete turnout lateral protection for the straight-through train in the line without human intervention.

Detailed Description
The invention will be further explained with reference to the drawings.
Referring to fig. 2-4, the interconnection CBTC system tie line switch control method of the present invention includes the following steps:
firstly, at least one positioning operation relay is added for the side turnout prevention. Specifically, the interconnection line turnout of the interconnection line is defined as a main access body turnout and a side anti-turnout, and the main access body turnout and the side anti-turnout are controlled by different interlocks. And positioning operation relays are respectively added for the side-protection turnout and the main access turnout, and preferably two positioning operation relays are added. Two positioning control relays are arranged for each turnout, and a command side needs to control the two relays to suck and fall simultaneously. The commanded interlock will automatically operate the corresponding switch to position only upon detection of simultaneous pick-up of both relays.
When the train on one line pulls the turnout of the main access road to be positioned through the interlocking of the line, the side turnout is automatically driven to be positioned through the interlocking of the other line through the positioning control relay.
The positioning operating relay is deactivated by default, and when the train is running in the line, the main route switch P1 and the side anti-switch P2 are required to be positioned. When a train on a line pulls a main turnout of an access way to be positioned through the interlocking of the line, a positioning control relay of a side turnout is activated, and the side turnout is automatically driven to be positioned when the interlocking of the line to which the side turnout belongs detects that the positioning control relay is activated.
When the train of one line runs in a cross-line mode, the line is interlocked to arrange a departure approach from a departure platform to a boundary, and an approach main body turnout is pulled to be in a reverse position; the interlocking of the other line is that the trains are arranged from the boundary to the receiving access of the receiving platform, and the side is pulled to prevent the turnout from being reversed.
And fourthly, when the interlocking of the other line fails, the side turnout can be manually locked and positioned, and the normal operation of the line is ensured.
The following is described in a specific scenario:
scenario a, train operation in the line, P1 and P2 initial positions are in reverse:
as shown in fig. 3, train T1 stops at platform 1 on route a, and the next platform is platform 2 on the route. The line a interlock aligns the interlocked route from traffic signal X1 to X2, with P1 being the main route switch and P2 being the side switch. Line A toggles P1 to position and activates the position-operated relay of P2. Line B interlock checks that both position control relays of P2 have been activated, automatically pulling switch P2 to position. Line a interlocks while detecting the position of P2, detects that the position of P2 is already in place, interlocks into line X1-X2 are authorized, and platform 1 outbound signal X1 turns on green.
Scenario b, train operation in the line, P1 and P2 initial positions are in positioning:
as shown in fig. 3, in scenario a, train T1 stops at station 1 of line a, and the interlock line is routed to X1-X2, since P1 and P2 are already in position, line a interlock does not require pulling P1, nor does it activate the position-controlled relay of P2. Line a interlock detects that P1 and P2 are already in place, authorizes access to X1-X2, and leaves signal X1 to turn on green lights.
Scenario c, train line crossing operation:
as shown in fig. 3, in the route a train T1, the train T1 is operated in a cross-track manner, and the route a is interlocked with the departure approach from the departure platform 1 to the route boundary, and the switch P1 is pulled to the reverse position. The line B interlocks the pick-up approach of the train from the boundary to the pick-up platform 3, pulling switch P2 to the reverse position.
And the line A calculates the mobile authorization of the train to the line boundary, splices the mobile authorization calculated and forwarded by the line B, and forwards the spliced mobile authorization to the train to enable the train to switch without stopping.
Scenario d, train operation in this line, cross-line interlocking fault:
as shown in fig. 4, train T1 stops at station 1 on line a and the next station is station 2 on line a, the interlock failure of line B. If P1 and P2 are already in place, T1 is not affected. If P1 and P2 are in the reverse position, P2 cannot be carried by P1, and P2 needs to be manually operated and locked in position.
Scenario e, train line-crossing operation, train receiving or departure interlock failure:
because the turnout under fault interlocking control cannot be pulled, the turnout is operated and locked at a fixed position, the normal operation of a train in a line is ensured, and the train crossing is cancelled.
Scene f, when the train operates over-line or does not have a train, the fault of the positioning control relay is absorbed:
because the positioning control relay of each turnout is provided with two relays, the corresponding turnout can be automatically controlled to be positioned only when the interlocking detects that the two relays are sucked up simultaneously, and the normal operation is not influenced by the fault suction of the single relay.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
