Problems solved by technology

[0004] In the prior art, the mature acquisition card on the market is used to collect the data processed by the analog-to-digital conversion and digital signal processing module to the PC, and the PC is used for processing. This type of acquisition card has a single function and only completes the data acquisition function. , has no processing function, and at the same time, PC processing uses software processing methods, and the software processing method is slow. In view of the large amount of data in this system and the characteristics of complex processing algorithms, it cannot be realized in real time, and there is a shortcoming of data loss, resulting in system existence.

Abstract

The invention provides an implementation method of an optical fiber vibration processor system, which is applied to an electronic signal processing system of a positioning type distributed vibration sensing system in the boundary security protection field and can effectively give an alarm for an intrusion event. In the invention, the large-scale and high-performance combined structure of FPGA andDSP is adopted. The scheme has the advantages that the FPGA not only has strong parallel processing capacity but also has quick processing speed (hardware processing), thus algorithms having large operating amount or rigorous speed requirements are implemented in the FPGA, and the DSP has the advantage of processing complicated algorithms (such as SVM algorithm). Thus, by combining the FPGA and the DSP, the invention can greatly improve the processing performance of the system, simultaneously meets the real-time requirement of the system and reduces the rate of missing report.

Description

technical field [0001] The invention relates to the field of perimeter security, and in particular to a method for realizing an optical fiber vibration processor system applied to the field of perimeter security. Background technique [0002] At present, the security systems applied to perimeter alarm mainly include: microwave alarm system, active infrared alarm system, leaking cable perimeter alarm system, static induction perimeter alarm system and camera video recognition system, etc. However, when the above-mentioned traditional perimeter alarm system is applied to monitoring under long-distance conditions, there will be many problems. For example, monitoring methods such as microwave alarm system or active infrared alarm system can only be used in line-of-sight and flat areas, and are greatly affected by environmental factors such as terrain heights, twists and turns, turns, and bends. Influenced by climate, the accuracy rate is also lower. At the same time, since the...
