摘要
基于物联网(internet of things,IOT)平台,设计一种物联网网关架构及设备的接入。将物联网网关分感知接口层,协议适配层,数据模型同步层,平台通信层。将感知接口层和协议适配层称为网关内部模块;数据模型同步层和平台通信层称为网关设备接入模块。网关设备接入模块实现与网关内部模块的通信以及设备的接入,选用node. js作为运行平台,测试结果表明,可以实现多种设备的接入,实现了设备与网关设备模型数据的同步更新。
An access of gateway architecture and device of IOT is designed based on the Internet of things （lOT） platform. The lOT gateway is divided into a perceptual interface layer, a protocol adaptation layer, a data model synchronization layer, and a platform communication layer. The perceptual interface layer and the protocol adaptation layer are referred to as internal gateway modules; the data model synchronization layer and the platform communication layer serve as gateway device access modules. Communication and access of device between the gateway device access module and the internal gateway modules are implemented. As node. js is selected as the operating platform,the test result shows that multiple devices access can be achieved and the data from device and gateway device model can be updated synchronously.
