Design of Mobile Terminal in Spectral Sensing Internet of Things Based on Android Platform

提出了一种基于Android系统的光谱传感物联网移动终端软件设计,可以实现用户与光谱传感物联网的数据交互及数据处理功能;移动终端包括用户信息,节点信息,数据信息三个模块,使用ViewPager类搭建双列表界面展示节点信息,使用SOAP协议与云服务器进行数据交互,可以将得到的光谱以及环境数据以图像的形式展示,并支持图像的保存功能;进一步在移动终端上实现了光谱数据的归一化,一阶微分,二阶微分,峰值寻找等数据处理功能;环境数据包括温度、湿度、二氧化碳浓度以及光照强度数据,可以实时显示最新环境数据,也可选择时间段对环境数据进行查询绘图;经测试,该应用程序运行稳定,可满足光谱传感物联网移动终端的基本应用需求。

This paper proposes a mobile terminal software design of the spectral sensing Internet of Things(IOT)based on Android system. It can realize data interaction and data processing functions between user and spectral sensing IOT. Three modules including user information, node information and data information. Using the ViewPager class to build a double-list interface to display node information, using the SOAP protocol to do the data interaction with the cloud server. The resulting spectral and environmental data can be displayed in the form of graphic and it can be saved in the phone. Furthermore, the software realizing spectral data processing function such as normalization, first-order and second-order differential, peak-finding. Environmental data including temperature, humidity, carbon dioxide concentration and light intensity data. It can display the latest environmental data in real time, and also can select time period to query and plot environmental data. After testing, the developed software runs stably and can realize the spectral sensing IOT mobile terminal software requirements.
