基于Android系统的温室异构网络环境监测智能网关开发
为实现温室环境监测中异构网络的统一管理,该文开发了以Exynos4412为核心处理器的智能网关,设计了基于Android的智能网关应用软件。异构网络管理过程为:配置网关通信接口、数据采集单元、传感器数据流的字段描述等信息,建立基于XML的信息配置文件,数据接收线程根据配置文件描述与接收数据流逐字节段比对,实现传感器数值从数据流中定位、解析、数值转换得到监测参数实际值,并与监测参数ID组成键值关系,最终存储于SQLite数据库,提供接口给上层模块进行实时数据查询和历史数据查询。系统对Zigbee、RS-485、Wi-Fi3种异构网络进行了试验,14 d的运行结果表明,智能网关实现了监测参数解析、...

Summary: | 为实现温室环境监测中异构网络的统一管理,该文开发了以Exynos4412为核心处理器的智能网关,设计了基于Android的智能网关应用软件。异构网络管理过程为:配置网关通信接口、数据采集单元、传感器数据流的字段描述等信息,建立基于XML的信息配置文件,数据接收线程根据配置文件描述与接收数据流逐字节段比对,实现传感器数值从数据流中定位、解析、数值转换得到监测参数实际值,并与监测参数ID组成键值关系,最终存储于SQLite数据库,提供接口给上层模块进行实时数据查询和历史数据查询。系统对Zigbee、RS-485、Wi-Fi3种异构网络进行了试验,14 d的运行结果表明,智能网关实现了监测参数解析、存储和显示功能与配置信息描述实现了对应,满足温室环境监测异构网络的统一管理要求,具有较好的稳定性,可进一步扩展异构网络。 |

The gateway of internet of things was used for heterogeneous networks access and transmission of data protocol among the networks. In order to realize the unified management of heterogeneous networks that were used for greenhouse environment, an intelligent gateway with Exynos4412 as the core processor was developed, which has high speed operation capability and can be expanded for various communication mod |
