Fig. 2 is a schematic flow chart of the operation management of the degraded vehicle of the TACS system provided in this embodiment, where the method includes:
when a normal train on a line fails, the TMC automatically identifies the train as a degraded train and informs a resource controller SC to ensure that the SC maintains resources allocated before the failure for the degraded train so that the degraded train is not allocated to other trains, meanwhile, the SC negotiates with other trains about the resources of a degraded train operation authorization area associated with the position of the failed train, and after the resources occupied by other trains are released, the resources are preferentially allocated to the degraded train to ensure the operation safety;
TMC sends the information of the degraded vehicle (including the fault position thereof) to an intelligent scheduling system ATS;
after the dispatching terminal confirms, the ATS automatically plans a next operation path request according to the destination and the state of secondary detection equipment (SDD) where the train position is located, and sends the next operation path request to the TMC;
the TMC negotiates resources on a running path with the SC and other trains through a degraded train running authorization area according to a running path request received from the ATS, a degraded train position and a line running direction;
after the SC allocates resources for the degraded vehicle operation authorization area, opening an entrance protection annunciator, and authorizing the degraded vehicle to pass through the annunciator;
and after the degraded vehicle completely enters the operation authorized area of the degraded vehicle, the SC releases the resources associated with the operation authorized area of the previous degraded vehicle.
The degraded train is a train with communication failure between trains or is not provided with a TACS system train.
The method provided by the invention is used in the TACS, and the operation of the degraded vehicle is controlled in an automatic blocking mode. The method detects the position of the degraded vehicle through secondary detection equipment (SDD), and the ATS automatically sends a running path request to the TMC, the TMC replaces the degraded vehicle, negotiates resource allocation with the SC and other trains through a degraded vehicle running authorization area, and after the SC allocates resources for the degraded vehicle running authorization area, an entrance protection annunciator is opened, a driver is authorized to control the vehicle to run, so that the mutual influence between the degraded vehicle and the normal train with vehicle-to-vehicle communication is reduced, the running efficiency of a line is improved, and the safety of mixed running of the degraded vehicle and the normal train with vehicle-to-vehicle communication is ensured.
Further, on the basis of the above embodiment, as shown in fig. 4, the TMC replaces the downgrader car to be responsible for performing information interaction with the ATS and other trains, including that the ATS and the TMC request to negotiate a movement request through a running path, a train with normal adjacent car-to-car communication negotiates resource allocation with the TMC communication to ensure interval confirmation of mixed running operation, and the SC allocates resources to the downgrader car through the resource requested by the TMC in the downgrader car running authorization area, so as to ensure that the downgrader car is safely identified and tracked in the line.
As shown in fig. 5, when the train completely enters the authorized area for operation of the downgraded train, the SC automatically releases the resources in the authorized area for operation of the downgraded train at the upstream for use by other trains, and sends a new operation path request to the SC to automatically request the resources in the authorized area for operation of the downgraded train at the downstream through the ATS, so as to achieve the purpose of automatically blocking the train.
Further, on the basis of the above embodiment, the authorized area for the operation of the degraded vehicle is usually one station in the train and one area, as shown in fig. 6, the resource of the authorized area for the operation of the degraded vehicle is automatically released by the SC, and the resource of the authorized area for the operation of the next degraded vehicle is negotiated with other trains and the SC according to the request from the ATS operation path, which is convenient for the driver to delay the rapid operation according to the display of the traffic signal. According to the method, automatic inter-station blocking can be realized for the degraded vehicles only by arranging a small amount of secondary detection equipment (such as an axle counting) and an outbound signal machine beside the track, so that the running safety of the degraded vehicles is guaranteed. Meanwhile, the short-distance degraded vehicle operation authorization zone of one station and one section reduces the influence of the degraded vehicle on other trains on the line in the operation process.
It should be noted that, in this embodiment, after the train becomes a downgraded train due to a fault, when a driver connects and manages the train, the train is started only after the wireless dispatching system and the control center dispatcher confirm that there is no other train at the front signal, and then the train is controlled to run to a maintenance or storage position according to the signal display.
For example, when a train has a fault, a dispatcher and a driver confirm the position and the train number information of the train, the driver is informed to manually drive the train to stop before a signal machine, and the dispatcher sets a destination for a degraded train. The ATS sends a running path request to the TMC, and the TMC negotiates resources of a downstream degraded vehicle running authorization area with other trains and the resource management SC, so that the train with normal vehicle-to-vehicle communication at present timely adjusts a scheme according to the degraded vehicle running authorization area, and if other trains with normal vehicle-to-vehicle communication are arranged at the downstream of the position of the degraded vehicle, the trains are redistributed after the normal trains leave and release the resources, and the safety of a driver in manually driving the trains in the degraded vehicle running authorization area is guaranteed.
Further, on the basis of the above embodiment, at the boundary of the TACS system, the dispatcher manually requests the travel path in the train pickup direction to allow the train to be inserted into the TACS system from the non-TACS area in a degraded train mode, and perform safety management, and the flow diagram is shown in fig. 3:
after the train stops in front of the TACS boundary entrance signal machine, the ATS generates a running path request according to a destination manually set by a dispatcher;
the TMC negotiates resources with other trains and a resource management SC through a degraded train operation authorization area, and after the SC allocates resources for the degraded train, an entrance annunciator at the TACS boundary is opened to authorize the train to enter the TACS system;
TMC automatically generates a degraded vehicle at the TACS boundary;
and the degraded vehicle continuously operates to realize positioning, and after the TACS system finishes registration, the normal train of vehicle-to-vehicle communication is converted for management, otherwise, the management is continuously carried out through the authorized operation area of the degraded vehicle.
Further, when the degraded vehicle completely leaves the TACS system management area, the TMC will log off the degraded vehicle, and automatically release the last degraded vehicle operation authorization zone resource on the leaving path.
The method provides a safe and reliable mode for inserting/leaving the TACS system for the degraded vehicle through manual intervention of a dispatcher, and improves the efficiency of operation modes such as maintenance, rescue and insertion.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
