AD-HOC NETWORK-BASED TRAIN DYNAMIC GROUPING AND UNGROUPING METHOD AND SYSTEM

An ad-hoc network-based train dynamic grouping and ungrouping method, said method comprising train dynamic grouping and train dynamic ungrouping; the train dynamic grouping comprises: after a rear train group enters a U code section, if a grouping condition is satisfied, two train groups are grouped together; and the dynamic ungrouping comprises: two train groups within a fleet receive an ungrouping instruction during operation, and if an ungrouping condition is met, the two train groups are ungrouped; and said method further comprising: during operation of the two train groups within the fleet, a rear train group has a speed of 0, and if the ungrouping instruction is received, the two train groups are ungrouped. A method designed in the present invention implements soft connection by means of an ad-hoc network, a fleet of trains are able to flexibly group together, and multiple tracks are amply utilized. At train departure, first grouping and then departing is used to improve train departure efficiency. When train transport volume is increased, a 5000 ton standard train may be used, thereby avoiding high costs caused by adding effective track. Further disclosed is a dynamic grouping and ungrouping system.
