WIRELESS DATA COLLECTION SYSTEM, AND WIRELESS DATA COLLECTION METHOD

摘要

The present invention is capable of coping with an early stage fault in a communication path. A wireless data collection system (1) comprising a plurality of wireless sensor terminals (10) and a server (30) that acquires data from the plurality of wireless sensor terminals. If a polling packet is received from the server (30), the plurality of wireless sensor terminals (10) broadcast prescribed terminal information pertaining to a terminal in question to the wireless sensor terminals surrounding the terminal in question. The wireless sensor terminals (10) receive and hold prescribed terminal information which has been broadcast from the other wireless sensor terminals surrounding the terminal in question and pertains to the other wireless sensor terminals, and send the prescribed terminal information pertaining to the terminal in question and the prescribed terminal information pertaining to the other wireless sensor terminals to the server (30) as a polling response to the polling packet.
