DISTRIBUTED REDUNDANCY CONTROL METHOD AND SYSTEM FOR INTELLIGENT TRANSPORTATION NETWORK

Title:

DISTRIBUTED REDUNDANCY CONTROL METHOD AND SYSTEM FOR INTELLIGENT TRANSPORTATION NETWORK

Document Type and Number:

WIPO Patent Application WO/2016/127950

Kind Code:

A1

Abstract:

A distributed redundancy control method and system for an intelligent transportation network. The method comprises: with respect to communication control nodes (62-67), the communication control nodes transmit a master device election packet to the other communication control nodes, elect a master device (67) among the multiple communication control nodes on the basis of priorities configured for the communication control nodes, and back up data of the communication control nodes into the master device (67) (S202); the master device (67) transmits a state detection packet to the other communication control nodes (62-66) and, with respect to the other communication control nodes (62-66) other than the master device, when a response packet from the communication control nodes for the state detection packet is such that the communication control nodes are incapable of executing an action for controlling a subordinate device of the communication control nodes, executes an action for controlling the subordinate device of the communication control nodes, and the master device (67) adjusts control times for signal lights of corresponding junctions on the basis of junction traffic volumes corresponding to the communication control nodes (62-67) in the redundancy network (S203). The method implements distributed redundancy control for the intelligent transportation network.
