Abstract
A detection system for measuring one or more conditions within a predetermined area includes at least one fiber optic cable for transmitting light to and receiving scattered light from one or more nodes and a cover plate having an internal cavity. The cover plate surrounds the one or more nodes such that the one or more nodes are in communication with the internal cavity. A control system is operably coupled to the at least one fiber optic cable so that the scattered light received by the one or more nodes is transmitted to the control system. The control system analyzes the scattered light to evaluate a condition at the one or more nodes.
Claims18
A detection system for measuring one or more conditions within a predetermined area comprising:
- at least one fiber optic cable for transmitting light to and receiving scattered light from one or more nodes;
- a cover plate having an internal cavity, the cover plate surrounding the one or more nodes such that the one or more nodes are in communication with the internal cavity;
- and
- a control system operably coupled to the at least one fiber optic cable so that the scattered light received by the one or more nodes is transmitted to the control system, wherein the control system analyzes the scattered light to evaluate a condition at the one or more nodes.
A method of measuring a condition comprising:
- transmitting light from a node of a fiber optic cable into an internal cavity defined by a cover plate surrounding the node;
- scattering the light within the internal cavity;
- receiving a portion of the scattered light from the internal cavity;
- communicating the scattered light to a control system;
- and
- analyzing the scattered light to evaluate a condition within the internal cavity adjacent the node.
