Method to detect earthquakes and locate epicenter using light source network

摘要

A method for the detection of seismic activity using a light source network, in particular a streetlight (43) located over several streets (42) is described herein. Each light source includes a control module having facilities for both telecommunications and short-range communications, the control module being grouped with other control modules and associated with a group controller in a short-range network or mesh network. Build up. Each control module includes a sensor that can detect seismic activity, and data regarding such activity can be transmitted to a central server via a group controller of each control module using telecommunications. . Even though the sensors are relatively inaccurate, because of the large number of such sensors present in the network, the server uses the geographic coordinate information provided by the control module to detect seismic activity, It is possible to analyze. Information about the epicenter of the earthquake can be determined and distributed to a control module near the detected seismic activity (50) to provide a warning light signal to the nearby residents.
