Smoke detection and localization based on cloud platform
A detection system for measuring one or more conditions within an area. At least one fiber optic cable transmits light wherein the at least one fiber optic cable defines a plurality of nodes arranged to measure the one or more conditions. A control system communicates with the at least one fiber optic cable such that scattered light and a time of flight record is transmitted from the at least one fiber optic cable to the control system. The control system includes a detection algorithm operable to identify a portion of the scattered light associated with each of the plurality of nodes. When determining an alert, the control system transmits data associated with a presence and magnitude of the one or more conditions at each of the plurality of nodes to a cloud computing environment and, in return, receives a notification based on the data transmitted.
