Abstract
(A1) Sicherheitszaun, umfassend ein mechanisches Sperrelement 1, welches dazu vorgesehen ist, ein Durchdringen des Zaunes zu verhindern und mindestens eine optische Faser 5, in welche mittels eines Senders ein optisches Signal 4 einkoppelbar ist, welches mittels eines Empfaengers empfangbar ist, wobei Veraenderungen des optischen Signals 4 aufgrund mechanischer Belastung der optischen Faser detektierbar sind und die optische Faser zumindest als Teil der Umhuellung 3 von zumindest einem Teilbereich des mechanischen Sperrelementes 1 ausgebildet ist, sowie ein darauf basierendes Verfahren zur Entdeckung von Eindringlingen an einem Sicherheitszaun.
DE 102007042454 A1 UPAB: 20090423 NOVELTY - The safety fence has a mechanical blocking unit (1) e.g. wire mesh, for preventing a penetration through the safety fence. An optical fiber (5) is provided, where an optical signal i.e. light wave (4), is injectable into the optical fiber using a transmitter. The optical signal is receivable by a receiver, where changes of the optical signal are detectable based on a mechanical load of the optical fiber. The optical fiber is formed as a portion of a casing (3) by a sub-region of the mechanical blocking unit. The optical fiber is made of a plastic material, and a core (2) is made of a metal. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for detecting an intrusion on a safety fence. USE - Safety fence for encircling a safety area. ADVANTAGE - The optical signal is injectable into the optical fiber using the transmitter and receivable by the receiver, where the changes of the optical signal are detectable based on the mechanical load of the optical fiber that is formed as the portion of the casing by the sub-region of the mechanical blocking unit, thus allowing the reliable notification of the unauthorized intrusion into a safety area as well as the destruction of the safety fence encircling the safety area.
