WIRELESS COMMUNICATION PATH CONSTRUCTION METHOD, CHILD DEVICE, AND WIRELESS COMMUNICATION SYSTEM

摘要

To quickly and reliably establish a wireless communication network using a wireless device in a wireless communication system in which wireless devices are dispersedly arranged in each vehicle of a train.SOLUTION: A wireless communication system 1 includes a plurality of wireless devices 10 arranged in each vehicle. A parent device 12 transmits, for example, formation information of the train acquired from a central device 30 to each child device 14 by wired communication via a signal transmission line 20. Each of the child devices 14 checks the connection order of the vehicles of the own train and other wireless devices 10 arranged in each vehicle on the basis of the received formation information, and in the distance order in the direction toward the parent device 12 (upward direction), direct wireless communication with the other wireless device 10 is attempted and it is determined whether or not the wireless communication can be performed. The parent device 12 acquires the result of the direct wireless communication determination in each of the child devices 14, creates a route table for the child device 14, and transmits the route table.SELECTED DRAWING: Figure 1
