example 1

[0087] Dynamic marshalling example 1: The dynamic marshalling of a single vehicle tracking train group.

[0088] Such as 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 tra...

example 2

[0090] Dynamic grouping example 2: train group tracking dynamic grouping of bicycles.

[0091] 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

[0092] Example 3 of dynamic grouping: train group tracking dynamic grouping of train groups.

[0093] 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 Figure 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.

[0094] 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 present invention proposes a method and system for dynamic grouping and demarshalling of trains based on an ad hoc network. The method includes dynamic grouping of trains and dynamic demarshalling of trains; dynamic grouping of trains includes: Conditions, two train sets are marshaled; dynamic unmarshalling includes: the two train sets in the group receive unmarshalling commands during operation, and if the unmarshalling conditions are met, the two train sets are unmarried; also includes: in the group During the operation of the two train sets in the group, the speed of the following train set is 0. If the unmarshal command is received, the two train sets will be demarched. In the method designed by the present invention, the trains are no longer hard-connected by couplers, but softly connected by the self-organizing network. When the train volume increases, 5000-ton standard trains can be used, thereby avoiding the loss due to the increase of effective lanes. resulting in high costs. Group trains can be organized flexibly to make full use of multiple lanes. When starting the car, use the group first and then start the car to improve the efficiency of the car.

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...
