example 1

[0088] Dynamic marshalling example 1: The dynamic marshalling of a single vehicle tracking train group.

[0089] like figure 2 As shown, the train group Q{A,B,C,D} composed of train A, train B, train C and train D is running, and train E is normally tracking after the train group Q. Car A, car B, car C and car D communicate with each other through the ad hoc network established among them. Car E joins the ad hoc network and communicates with car A, which is not shown in the figure. The distance between car A, car B, car C and car D is L 间1 , L 间2 , L 间3 ; L 间1 Indicates the distance between the first train and the second train in the group network, L 间2 Indicates the distance between the second train and the third train in the group network, L 间3 Indicates the distance between the third train and the fourth train in the group network. Since A train, B train, C train and D train form a train group Q{A,B,C,D} to run, the train group Q controls A train, B train, C train ...

example 2

[0091] Dynamic grouping example 2: train group tracking dynamic grouping of bicycles.

[0092] The train group Q{A,B,C,D} composed of A train, B train, C train and D train is tracking the normal operation of the previous train F, such as Figure 4 shown. If the current marshalling plan is train group Q{A,B,C,D} and train F train marshalling as train group Q'{F,A,B,C,D}, then train A will be shortened according to the plan and the preceding car F The distance between trains, when train A enters the U code section, train A and train F will verify IDs with each other. After the verification is successful, train A continues to run until the marshalling condition is met, and train group Q is marshalled with train F to form a new train group Q'{F,A,B,C,D}, such as Figure 5 shown. In the train group Q, the distances between trains A, B, C and D are L respectively 间1 , L 间2 , L 间3 . After forming a new train group Q', the distance between train F and train A is L 间1 , the dis...

example 3

[0093] Example 3 of dynamic grouping: train group tracking dynamic grouping of train groups.

[0094] A train group Q consisting of cars C and D 后 {C,D} is tracking the train group Q consisting of car B and car A ahead 前 {A,B} works normally, such as Image 6 shown. If the current marshalling plan is train group Q 后 {C,D} and Q 前 {A,B} is grouped into train group Q 合 {A,B,C,D}, then train C shortens the distance with the preceding car B according to the plan, when train C enters the U code section, car C and car A check each other’s ID. After the verification is successful, the C car continues to run until the marshalling condition is met, and the Q car 后 {C,D} and Q 前 {A,B} marshalling, forming a new train group Q 合 {A,B,C,D}, such as Figure 7 shown.

[0095] Specifically, the dynamic unmarshalling includes: a first demarring and a second demarring; the dynamic train demarring also includes: receiving a dismantling plan, and setting a dismantling command according ...

Abstract

The invention provides a train dynamic marshalling and un-marshalling method and system based on an ad-hoc network. The method comprises train dynamic marshalling and train dynamic un-marshalling. Thetrain dynamic marshalling comprises the following steps that after a following train group enters a U-code section, if marshalling conditions are met, two train groups are marshaled. The dynamic un-marshalling comprises the steps that two train groups in a group receive an un-marshalling command in the operation process, and if the un-marshalling condition is met, the two train groups are un-marshaled; and in the operation process of the two train groups in the group, the speed of the following train group is 0, and if an un-marshalling command is received, the two train groups are un-marshaled. According to the method designed by the invention, hard coupling is no longer carried out between trains by adopting couplers, but flexible connection is realized by the ad hoc network, and when the transportation capacity of the trains is increased, a 5000-ton standard train can be adopted, so that high cost caused by adding effective station tracks is avoided. Group trains can be flexibly grouped, and a plurality of station tracks are fully utilized. During departure, marshalling and departure are performed in sequence to improve the departure efficiency.

Description

technical field [0001] The invention belongs to the technical field of traffic, and in particular relates to a method and system for dynamic marshalling and demarshalling of trains based on an ad hoc network. Background technique [0002] At present, the operation of heavy-duty trains (such as 20,000 tons) is mostly realized through the working mode of lengthening train formation and multiple locomotives (generally 3) combined traction. Longer train formations require longer effective strands. However, increasing the effective share channel involves land acquisition and other issues, and the cost is extremely high. At the same time, the use of multi-section train marshalling has led to the fact that ordinary station lanes can no longer meet the needs of its marshalling; marshalling often occupies intervals for operations, which seriously affects the operation of the main line; it takes about 120 minutes to marshal or unmarshal multi-car trains, and the efficiency is extreme...
