INFORMATION COLLECTION SYSTEM, RELAY TERMINAL, CONTROL METHOD FOR RELAY TERMINAL TO CONNECT TO CENTER SYSTEM, SENSOR TERMINAL, AND CONTROL METHOD FOR SENSOR TERMINAL TO CONNECT TO CENTER SYSTEM

摘要

An information collection system comprises a center system and relay terminals connectable to the center system via a network. the center system includes a first server for each of the relay terminals to initially connect to, a second server for each of the relay terminals to send sensor information and a third server configured to manage the first server and the second server. The relay terminal includes a first storage unit configured to hold relay terminal information for managing information on an operating channel to be used by the relay terminal and information to connect to the first server and a relay terminal operation start unit configured to select an operating channel to be used by the relay terminal from channels scanned based on information on candidate operating channels for the relay terminal received from the third server via the first server.
