Abstract

A first collecting device is connected to a first network to which a first sensor is connected, and to an external network. A second collecting device is connected to a second network to which a plurality of second sensors for measuring a second amount of observation are connected, and to the external network, and collects second sensor data. When the first collecting device cannot collect first sensor data through the first network, an adapter transfers the first sensor data to the second collecting device through the second network, and transmits the first sensor data to the first collecting device from the second collecting device through the external network.
