摘要（英）：

The invention relates to an optical fiber dual-mode coupling-based multi-prevention zone vibration detection device. The device comprises a basic signal detection module, at least one 1*N branching device, a signal transmission line and vibration monitoring units, wherein the basic signal detection module is connected with the signal transmission line, and the signal transmission line is connected with the input of the 1*N branching devices; one output end of each 1*N branching device and the corresponding vibration monitoring unit are used for detecting vibration signals; and one output end of each 1*N branching device and the signal transmission line are adopted as the communication bus of a next vibration detection unit. Compared with the prior art, the optical fiber dual-mode coupling-based multi-prevention zone vibration detection device of the invention realizes regional positioning vibration (intrusion) monitoring of objects in an extra-large range.
