GATEWAYS AND EARTHQUAKE DETECTION METHOD

摘要

[Problem] The purpose of this gateway is to improve determination accuracy when determining whether an earthquake has occurred within an area managed by the gateway by way of statistically processing vibration-related information from managed nodes when. [Solution] This gateway manages a plurality of nodes present in an area and has: a receiving unit that receives from at least some of the plurality of nodes vibration information about vibrations detected by the at least some of the plurality of nodes, and that receives from another gateway device earthquake information about whether an earthquake has occurred in another area managed by the other gateway device; a control unit that references the earthquake information for another area and determines whether there is an earthquake in the area; and a transmitting unit that, when an earthquake occurs in the area, transmits control information for when an earthquake occurs to the at least some of the nodes that transmitted the vibration information.
