With the progress of sensors and communication devices, various infrastructure data can be acquired by wireless connection. The data acquisition method using LPWA communication is highly anticipated because it does not require a radio communication license for installation, low power consumption and a large number of sensors can be installed at low cost. However, as the data characteristics of infrastructure, data during a disaster is the most needed, and continuous data collection and distribution is required even in the extreme situation of power loss. The authors are studying to realize a system that enables continuous monitoring status of multiple sluice gates even in a critical situation such as public communication disruption due to a long blackout caused by a huge typhoon. Including satellite utilization, enhancement of resilience of LPWA network data acquisition at power loss is discussed.
