Disaster response communication system and disaster response communication method

摘要

PROBLEM TO BE SOLVED: To transmit data of a sub communication line even if a failure occurs in a part of the sub communication line due to a failure of the main communication line in a dual communication line of a main communication line and a sub communication line between a disaster prevention center and a sensor. Provide a disaster response communication system to be performed. The present invention is a system including a main communication line and a sub communication line according to an LPWA standard communication method, and the sub communication line is always activated in the event of a disaster, and acquires environmental data around a measurement sensor. A measurement sensor, a data management server that manages environmental data, a main communication unit that performs data communication with the data management server on the measurement sensor and the main communication line, and a sub communication unit that performs data communication with the data management server on the sub communication line. , A repeater is provided between the base station that performs data communication between the sub-communication unit and the data management server, and one or more other repeaters are arranged in the communicable area of the repeater. , The communication path between the sub-communication unit and the base station forms a reconfigurable mesh network.
