摘要
边海防安全是国家安全的重要组成部分,分布式/准分布式振动光缆报警技术具有长距离、实时报警能力,可为我国漫长的陆地边境线与海岸线实时入侵检测与报警提供重要技术支撑。分析了散射型、干涉型、光纤光栅型以及多技术复合型振动光缆报警技术的原理、特点及缺陷,介绍了以上技术在边海防报警线路系统中的具体应用场景及敷设方式,展望了振动光缆技术在边海防应用前景和发展方向。
Border and coastal defense is an important part of national security.The distributed or quasi-distributed optical fiber vibration alarm system with long-distance and real-time alarm capability can provide important technical support for real-time intrusion event detection and alarm of the long land border and coastline of PRC.This paper focuses on different types of optical fiber vibration alarm system,such as scattering,interference,fiber Bragg grating and combined types.The principle,characteristics and defects of these technologies are analyzed.As for the technologies mentioned above,their specific application scenario and installation methods are introduced.Finally,the application prospect and development direction of optical fiber vibration alarm system in border and coastal defense are proposed.
