Optical fiber sensor network for monitoring wide-regional natural environments

我们研究的总体概念是构建一个可以广泛应用于光纤传感器环境监测领域的传感器网络。本研究以光纤传感系统的实现为重点，构建农业环境下土壤重力水远程监测网络。这项研究包括在同一条光纤线路上安装多点传感器，并通过使用互联网标准协议——简单网络管理协议（SNMP）来区分每个传感器的响应。为了扩大大面积监测的数据传输距离，本研究采用涂覆Ta2O5的HC-SPR传感器，波长为1310 nm。为了区分多点传感器的状态，构建远程数据采集传感器网络，提出了一种使用SNMP协议的方法。简而言之，这项研究的目标已经实现，拟议的方法也满足了所有规定的要求。

The overall concept of our study is to construct a sensor network which could be utilized in the wide area of environmental monitoring with fiber optic sensor. Focusing on the realization of a fiber optic sensor system, this research objective is to construct a remote monitoring network for soil gravity water in agricultural environments. The study involves the installation of multipoint sensors into the same fiber line and differentiates the response from each sensor by using the internet-standard protocol, Simple Network Management Protocol (SNMP). In order to extend the distance of data transmission for large-area monitoring, the study used an HC-SPR sensor coated with Ta2O5 and adopted a wavelength of 1310 nm. To distinguish the status of multi-point sensors and to construct remote data acquisition sensor networks, a method that uses SNMP is introduced. In a nutshell, the objectives of the study has been achieved and all defined requirements has been met with the proposed method.
