All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention. The method for detecting train collision according to the present invention will be explained and illustrated in detail by specific embodiments.
Fig. 1 is a schematic flowchart of a method for detecting a train conflict according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: when the signal machine is turned on, the planned vehicle T1 carrying the destination is received to trigger the departure information.
Step 102: the route R1 of the planned vehicle T1 is determined by using the position of the traffic signal as a start source node N1 of the planned vehicle T1 and the position of the destination as a terminal destination node N2 of the planned vehicle T1.
Step 103: from the end destination node N2, a travel path L1 of a planned vehicle T2 having the position of the destination as an end destination node and an approach R2 of the planned vehicle T2 are determined.

Step 105: if the planned vehicle T2 is the destination node N2 that has reached the terminal or the destination node N2 that has left the terminal, it is determined that there is no conflict with the planned vehicle T2 after the planned vehicle T1 enters the route R1.
Step 106: if the planned vehicle T2 is not found to have reached the terminal destination node N2 or left the terminal destination node N2, whether the planned vehicle T1 conflicts with the planned vehicle T2 after entering the route R1 is judged according to whether the running path L1 of the planned vehicle T2 is within the range of the route R1 of the planned vehicle T1.
Step 107: if the running path L1 of the planned vehicle T2 is not within the range of the route R1 of the planned vehicle T1, determining that the planned vehicle T1 does not conflict with the planned vehicle T2 after driving into the route R1.
Step 108: and if the running path L1 of the planned vehicle T2 is within the range of the route R1 of the planned vehicle T1, determining that the planned vehicle T1 conflicts with the planned vehicle T2 after entering the route R1.
In this embodiment, it should be noted that the traffic signal for collision detection needs to be set to be turned on in advance, and the traffic signal is turned on by default in the following. Taking the case that the train normally runs on the main track as an example, the train is the planned train type. When a certain train (e.g., the planned train T2) leaves the platform and after a certain period of time, the following train (e.g., the planned train T1) does not need to stop at the platform (directly jump stop) due to a certain situation, it is necessary to determine whether there is a conflict with the route of the planned train T2 when the planned train T1 triggers the route of the leaving platform.
In this embodiment, it can be understood that the traffic signal collision detection function is started, before a row of planned vehicles T1 carrying destination information runs to a traffic signal, departure information needs to be triggered, the location of the traffic signal is used as a starting source node N1 of the planned vehicle T1, the location of a destination carried by the planned vehicle T1 is used as an end destination node N2 of the planned vehicle T1, and a node pair (N1, N2) is determined to be an entry R1 of the planned vehicle T1. According to the route R1, a starting source node N1 and a terminal destination node N2 (namely, a route starting track section and a terminal track section) of the route are searched in a compiled operation graph, then a planned line (an operation path L1) of a planned vehicle T2 ahead of the planned vehicle T1 is found out by the terminal destination node N2, a node pair (N3, N2) of the planned vehicle T2 capable of reaching the terminal destination node N2 is obtained from the L1, and the route formed by the node pair is R2.
The planned route to be triggered of the T1 vehicle is R1 (node pair N1, N2), the route which obtains the same destination of the T2 vehicle is R2 (node pair N3, N2), and the judgment is carried out through program logic: 1) If the planned vehicle T2 runs to the terminal destination node N2 or leaves the terminal destination node N2, namely a real track point is formed, the planned vehicle T2 is considered to have driven out of the route R2, and the routes of the two trains do not conflict with each other, so that the route R1 of the planned vehicle T1 can be normally triggered and does not conflict with the planned vehicle T2 in driving; 2) If the actual track point information of the planned vehicle T2 leaving or arriving at the terminal destination node N2 is not found, the current running path L1 of the T2 vehicle needs to be determined according to (N3, N2) and the position information of the planned vehicle T2, and if the running path L1 of the planned vehicle T2 is found to be within the range of the route R1 of the planned vehicle T1, the planned vehicle T1 is considered to run into the route R1 and then conflict with the planned vehicle T2; conversely, if the searched route L1 is not within the range of the route R1 of T1, it is considered that there is no collision.
In the operation of the subway, the train can run in a planned train mode according to a programmed running chart, the running density of the train needs to be increased for improving the carrying capacity of a line with large passenger flow, and conflict detection can timely find out whether conflicts exist in routes selected and arranged among the trains or not and improve the working efficiency of dispatching personnel. In actual operation, a dispatcher can select to close or open a plan conflict detection function for a signal at any time, when the system is opened, a route taking the signal as a starting end can be triggered as long as a train with an effective destination arrives at a trigger area, and therefore the planned train sequence passing through the conflict area does not need to be checked.
As can be seen from the above technical solutions, in the method for detecting a train conflict provided in the embodiment of the present invention, the node information (terminal destination node N2) of the route R1 to be arranged of the planned vehicle T1 is used to obtain the travel path L1 and the route information (route R2) of the preceding vehicle (planned vehicle T2), and the actual position information of the planned vehicle T2 is determined to determine whether the planned vehicle T1 and the planned vehicle T2 conflict with each other; if the actual position information of the planned vehicle T2 cannot be found, a collision determination is made as to whether or not the travel path of the planned vehicle T2 is within the range of the route R1 of the planned vehicle T1. Therefore, the embodiment of the invention does not judge the running conflict according to the running schedule of the train, judges whether the conflict occurs or not by acquiring the train route position information, and is closer to the actual train running condition, thereby reducing the condition of misinformation and having better practicability.
On the basis of the above embodiment, in the present embodiment, the determining, according to the end destination node N2, the travel path L1 of the planned vehicle T2 having the position of the destination as the end destination node and the route R2 of the planned vehicle T2 includes:
determining a travel path L1 of a planned vehicle T2 with the position of the destination as an end destination node according to the end destination node N2;
according to the running path L1 of the planned vehicle T2, a starting source node N3 of the planned vehicle T2 is determined, and the starting source node N3 and an end destination node N2 are determined as a route R2 of the planned vehicle T2.
In the present embodiment, it can be understood that the travel path L1 of the planned vehicle T2 is found in the compiled travel diagram according to the end destination node N2. Meanwhile, the starting source node N3 of the planned vehicle T2 that can reach the destination node N2 is acquired from the travel path L1 of the planned vehicle T2, and the node pair (N3, N2) is determined as the route R2 of the planned vehicle T2.
As can be seen from the above technical solutions, in the method for detecting a train conflict provided in the embodiment of the present invention, the node information (terminal destination node N2) of the route R1 to be arranged of the planned vehicle T1 is used to determine the travel path L1 of the planned vehicle T2, the start source node N3 of the planned vehicle T2 is obtained, and the route R2 of the planned vehicle T2 is determined according to the start source node N3 and the terminal destination node N2. It can be seen that no complex algorithms are involved.
On the basis of the foregoing embodiment, in this embodiment, the determining whether the planned vehicle T1 enters the route R1 and then conflicts with the planned vehicle T2 according to whether the travel path L1 of the planned vehicle T2 is within the range of the route R1 of the planned vehicle T1 includes:
and judging whether the planned vehicle T1 conflicts with the planned vehicle T2 after driving into the access R1 according to whether the intersection road section exists between the running path L1 of the planned vehicle T2 and the access R1 of the planned vehicle T1 in the running chart.
As can be seen from the above technical solutions, in the method for detecting a train conflict provided in the embodiment of the present invention, whether an intersection section exists between the travel path L1 of the planned vehicle T2 and the route R1 of the planned vehicle T1 in the travel diagram is determined by querying the compiled travel diagram, and whether a conflict exists between the planned vehicle T1 and the planned vehicle T2 after the planned vehicle T1 enters the route R1 is determined based on whether the intersection section exists between the planned vehicle T1 and the planned vehicle T2.
On the basis of the above embodiment, in this embodiment, the method further includes:
if the fact that the planned vehicle T1 conflicts with the planned vehicle T2 after driving into the route R1 is determined, an alarm prompt is generated, and a dispatcher judges whether to select the route R1 or not.
In this embodiment, it can be understood that, if it is determined that the planned vehicle T1 collides with the planned vehicle T2 after entering the route R1, the train collision detection ATS system sends an alarm prompt to a dispatcher to remind the dispatcher to determine whether to select the route R1.
According to the technical scheme, the method for detecting the train conflict provided by the embodiment of the invention can better assist the work of the dispatching personnel and improve the work efficiency of the dispatching personnel.
