Description

Boundary turnout resource management method, equipment and medium

Technical Field

The invention relates to the technical field of rail transit, in particular to a boundary turnout resource management method, equipment and medium.

Background

At present, when track traffic is arranged in China, a turnout is not arranged near the boundary of an area managed by a trackside resource controller WRC (Wayside Resource Controller) in most cases, because when the turnout is out of table, the trackside resource controller should conduct guiding safety side processing on a train, if the turnout is arranged in the boundary area of the trackside resource controller, and a railway system is not provided with a metering axle, whether the train enters the jurisdiction area of the next trackside resource controller is difficult to judge, so that the trackside resource controller is influenced to process a fault train. For example, two adjacent trackside resource controllers wrc_1 and wrc_2 are provided, a switch is arranged in the area where wrc_1 is close to the boundary with wrc_2, if a train is derailed at the switch and the track is not provided with a counting shaft, it cannot be determined whether the train enters the jurisdiction of wrc_2, and it cannot be determined whether the faulty train is handled by wrc_1 or wrc_2.

However, in some specific-terrain road sections or old-fashioned track sections, there are cases where switches are arranged in the boundary region of the trackside resource manager, so a feasible control method is needed to be proposed urgently, and control of the trackside resource controller on the train applying for switch resources under the condition of arrangement of the boundary switches in the jurisdiction is achieved.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

The invention provides a boundary turnout resource management method, wherein the boundary turnout is a turnout which extends from a vertex along the forward direction and the reverse direction of the turnout and has an influence area length exceeding that of a trackside resource controller jurisdiction area, a signal system comprises a train controller and two trackside resource controllers WRC_1 and WRC_2 adjacent to the train travelling direction, the signal system generates a control token and grants the control token to the trackside resource controllers in the jurisdiction area according to the train state, and only the trackside resource controllers holding the control token can grant or release a turnout resource application sent by the train controller, and the boundary turnout is arranged at a position, close to the WRC_2 boundary, of the WRC_1 jurisdiction area. The boundary turnout resource management method is shown in fig. 12, and specifically comprises the following steps:

1) Initializing a track system to generate a control token as shown in fig. 1, and distributing the control token to a next trackside resource manager wrc_2 as shown in fig. 2;

2) When there is a train passing the boundary switch on the previous trackside resource manager WRC _1, WRC _1 acquires the control token for WRC _2,

step S21, a train controller on the train applies for turnout resources to the WRC_1 as shown in FIG. 3;

step S22, the WRC_1 applies for a control token to the WRC_2 as shown in FIG. 4;

step S23, WRC_1 acquires a control token, and WRC_2 enters a blocking state as shown in FIG. 5;

step S24, the WRC_1 grants the turnout resources to the train controller as shown in FIG. 6, applies for returning the turnout resources to the train controller once every cycle, and applies for returning the control token to the WRC_1 once every cycle by the WRC_2;

3) When the train on the boundary turnout is derailed, the track system starts a derailing abnormal mode, WRC_1 maintains a control token, and WRC_1 and WRC_2 enter a blocking state as shown in FIG. 7;

4) The derailment abnormal mode is relieved, the track system is initialized again,

step S41, the train is removed from the turnout area and driven away from the turnout area, and WRC_1 applies for returning turnout resources to the train controller as shown in FIG. 8;

step S42, returning the turnout resources to WRC_1 by the train controller as shown in FIG. 9;

step S43, the blocking state of WRC_1 is relieved, and WRC_2 applies for returning the control token to WRC_1 as shown in FIG. 10;

step S44, returning the control token from wrc_1 to wrc_2 as shown in fig. 11;

in step S45, wrc_2 is released.

When the wrc_1 applies for returning the switch resource to the train controller in the step S24, if the train does not leave the switch area, the train controller maintains the switch resource; if the train completely leaves the turnout area, the train controller releases the turnout resource authorization and returns the turnout resource to WRC_1. When wrc_2 applies for returning the control token to wrc_1 in step S24, if a train applies for switch resources to wrc_1 on a switch in the jurisdiction area of wrc_1, wrc_1 maintains the control token; if WRC_1 does not receive any switch resource grant application, WRC_1 returns the control token to WRC_2.

In addition, the entering of the wrc_1 or wrc_2 into the blocking state means that the wrc_1 or wrc_2 blocks the influence area in the respective jurisdiction area, and any vehicle except for the train on the switch is not allowed to enter the corresponding influence area; the lockout state release of wrc_1 or wrc_2 refers to the dispatch of a person by wrc_1 or wrc_2 to clear the area of influence in the respective jurisdiction, including the following three cases: 1. personnel determine derailment recovery, and the train can normally run; 2. the derailment vehicle only leaves the turnout area, because the train cannot derail as long as the train leaves the turnout area, and does not necessarily leave the influence zone;3. the cleaning of the influence zone is to clean other unknown trains or not, and is influenced by derailment trains, and the influence zone is wrongly intruded in the derailment. Wherein the length of the impact zone index zone is equal to the maximum stopping distance of the train plus the total length of the train.

The invention provides a feasible control system and a method for realizing control of a trackside resource controller on train application turnout resources under the condition of district boundary turnout arrangement, when a train is derailed on WRC_1, the derailed train possibly rushes out of the boundary of WRC_1 to enter the jurisdiction area of WRC_2 because of the adjacent WRC_2, and other vehicles possibly enter the influence area of the WRC_2, but the WRC_1 and the WRC_2 are blocked, so that the influence area of any other vehicle can not enter the fault vehicle is ensured, the safety and normal operation of other trains are ensured, and the safety of the whole rail transit is improved.
