Data collection system

Abstract

An object of the present disclosure is to enable a plurality of sensor terminals to cooperate when an event occurs. The present disclosure is a data collection system that collects sensing data detected by a sub-sensor terminal and a main sensor terminal having different sensing targets in the management node, in which the sub-sensor terminal transmits an event occurrence notification using an extension area of a layer 2 communication protocol when sensing a sensing target of the own apparatus, the management node transmits an instruction according to the event occurrence notification to the main sensor terminal when receiving the event occurrence notification from the sub-sensor terminal, and the main sensor terminal executes an operation defined by the instruction in response to reception of the instruction from the management node.

Dependencies are inferred from the claim text.
