Description
技术领域
本发明涉及植被保护,具体涉及基于光纤传感的重点植被保护装置。
背景技术
植被指地球表面某一地区所覆盖的植物群落。依植物群落类型划分,可分为草甸植被、森林植被等。它与气候、土壤、地形、动物界及水状况等自然环境要素密切相关。从全球范围可区分为海洋植被和陆地植被两大类。但由于陆地环境差异大,因而形成了多种植被类型,可将其划分为植被型、植物群系和群丛等多级分类系列。还可分为自然植被和人工植被。人工植被包括农田、果园、草场、人造林和城市绿地等。自然植被包括原生植被、次生植被等。由于现在的环境越来越差,并且濒临灭绝的植被种类也越来越多,政府越来越重视重点植被保护。
发明内容
针对上述问题,本发明提供了基于光纤传感的重点植被保护装置,本发明在应用时可对重点植被进行实时保护,当有人或动物靠近植被时,便会立马得知。
本发明的目的主要通过以下技术方案实现:
基于光纤传感的重点植被保护装置,包括分布式布里渊传感***和重点植被,所述分布式布里渊传感***中包括光纤,所述光纤将重点植被围绕至少一圈。
进一步地,所述分布式布里渊传感***包括泵浦光路和连续光路,所述泵浦光路和连续光路中的激光相向而行,所述泵浦光路中的激光与连续光路中的激光的频差为10.8GHz。
进一步地,所述泵浦光路和连续光路中均设有多个中继站,所述中继站用于放大泵浦光路和连续光路中的激光。
进一步地,所述中继站中设有掺铒光纤放大模块,所述掺铒光纤放大模块对经过的激光进行放大。
与现有技术相比,本发明具有以下有益效果:本发明包括分布式布里渊传感***和重点植被,分布式布里渊传感***中包括光纤,光纤将重点植被围绕至少一圈,当有人或动物靠近重点植被附近并触动光纤时,分布式布里渊传感***将会得到传感信息,所述传感信息用于报警,得到传感信息便可知晓光纤某处发生压力变化,并且分布式布里渊传感***的传感速度快,可迅速得到压力变化信息。
