Description

实现终端设备即插即用管理的能力开放平台、 方法及网关 技术领域
本发明涉及物联网中接入终端设备管理的技术， 尤其涉及一种实现终 端设备即插即用管理的能力开放平台、 设备识别方法及网关。 背景技术
物联网中一大难题就是终端设备协议和标准繁多， 各终端设备厂家、 联盟和组织都制定了各自的通信协议和标准， 这为物联网网关 （例如家庭 网关） 实现终端设备的接入和管理等带来了巨大的困难。 更糟糕的是在物 联网应用中设备具有高移动性特点， 例如某人去朋友家串门时可能随身携 带血压监测仪、 血糖监测仪等便携设备， 这使得物联网网关需要随时面对 各种新设备的接入。 随着物联网应用的发展， 物联网网关已经不单只是实 现终端设备的接入和数据传输而是成为实现设备接入、 管理、 控制和服务 的本地控制中心， 例如现有的高档物联网家庭网关已经带有触屏控制界面， 在网关界面上会显示家庭内各种设备的运行状态并且通过网关控制界面可 以控制家庭内的照明、 空调和电视等设备。
显然为了实现所有设备的接入、 管理、 控制和服务而在一个网关中实 现成百上千种并且还在不断增加中的协议是不可行的。 而现有的网关一般 都只实现一种或少数几种协议， 对于采用其它协议的设备将不能接入网关 和被网关控制。 例如中国移动在宜居通应用中推出的物联网家庭网关， 其 网关只支持满足中移制定的 WMMP协议的终端设备接入和控制，用户通过 网关可以查看家庭门窗开关情况、 控制空调和进行家庭布 /撤防。 其中， 所 述 WMMP 协议是中国移动为规范物联网终端与机器到机器 （M2M， Machine-to-Machine )平台间的数据通信、 实现 M2M平台对物联网终端的 统一管理而制订的规范。 M2M 用来表示机器对机器之间的连接与通信， M2M是物联网的构成基础。
综上所述， 为了解决上述设备协议和标准繁多难题， 通过对网关应用 场景进行分析可以发现。 从宏观上看物联网网关需要实现成百上千种不同 协议， 但从微观上看单个网关在应用中同时只需要支持几种或十几种协议， 这是单台网关能力所能够实现的。 所以解决协议和标准繁多难题的关键就 是实现网关能够动态的根据其有效范围内需要接入和控制的设备类型加载 需要的模块来实现设备的即插即用。 而要实现设备即插即用其中一个重点 就是找到一种可用性好的方法使得网关能够识别其需要接入的设备类型， 然而目前并未有这样的方案。 发明内容

在本发明实施例中： 网关通过终端授权机制来获取终端设备的标签信 息， 调用能力开放平台的设备识别服务识别未接入网关的终端设备。
以下简单对本发明的方案及其优越性做一总结描述， 后续再对方案具 体阐述。
由于条形码、 二维码和射频识别（ RFID )标签越来越多的被用户使用， 这些标签信息的应用技术都可以作为终端设备的唯一标识， 而且智能终端 已经具有条形码和二维码的扫描功能， 不久的将来， 智能终端还会普及 RFID标签读取能力， 可以说除了现有的智能手机这种终端设备之外， 只要 具有摄像头的设备都可以配置为读取条形码、 二维码， 因此， 利用条形码、 二维码和射频识别 （RFID )标签这些标签信息的应用技术成为可能， 且例 如广泛使用的智能手机等移动设备， 相比位置固定的物联网网关设备具有 不受位置限制和使用方便的优势。
一、 本发明实施例中， 一种利用标签信息识别未接入网关的终端设备 的方案为： 网关授权具有标签信息读取能力的且已经接入网关的终端设备 作为替代网关进行标签信息采集的设备， 通过该具有标签信息读取能力的 且已经接入网关的终端设备进行其他未接入网关的终端设备的识别 （可以 由该具有标签信息读取能力的且已经接入网关的终端设备读取其他未接入 网关的终端设备的条形码、二维码或 RFID标签信息， 并将读取的标签信息 发给网关， 网关根据该标签信息实现对其他未接入网关的终端设备的识 别）， 进而对识别的设备进行诸如接入和控制的管理及提供服务势必会大的 提高本方案的易用性， 这里， 带标签信息读取能力的、 已经接入网关的终 端设备实际上是网关目前能支持协议的设备， 这样， 通过有限的、 网关目 前能支持协议的设备通过标签信息对更多的不支持目前网关协议的设备进 行识别， 从而使网关能够识别网关自身支持协议之外但需要接入的终端设 备的设备类型， 以便兼容对所有终端设备的即插即用管理和提供服务， 而 且这种方案对网关自身没有改动， 减少了修改网关的制造成本。
二、 本发明实施例还有一种利用标签信息识别未接入网关的终端设备 的方案， 是对网关自身进行改动， 增加了网关的标签信息读取能力， 也可 以达到方案一区别于现有技术的优越性， 即： 通过有限的、 网关目前能支 持协议的设备通过标签信息对更多的不支持目前网关协议的设备进行识 别， 从而使网关能够识别网关自身支持协议之外但需要接入的终端设备的 设备类型， 以便兼容对所有终端设备的即插即用管理和提供服务。 但是， 会额外增加修改网关的制造成本。
下面结合附图对技术方案的实施作进一步的详细描述。
图 1 为本发明实施例能力开放平台的组成结构示意图， 该能力开放平 台配置为根据网关上传的标签信息对未接入网关的终端设备进行识别。 具 体的， 该能力开放平台如图 1 所示， 包括设备识别服务单元、 认证服务单 元、 标签信息注册服务单元、 地址注册服务单元、 上传服务单元。 通过这 些单元， 能力开放平台能提供设备识别服务、 厂商认证服务、 标签信息注 册服务、 模块和文件下载地址注册服务、 模块和文件上传服务。
设备识别服务单元配置为根据网关上传的未接入网关的终端设备的标 签信息识别出未接入网关的终端设备的设备类型， 并结合所述设备类型和 所述网关上传的网关自身信息 （例如网关型号、 软件版本号等） 匹配出网 关进行设备识别、 管理和服务所需的模块和文件， 将该所需的模块和文件 直接反馈给网关、 或者将该所需的模块和文件的下载地址反馈给网关， 由 网关后续根据下载地址自行下载模块和文件， 优选是将下载地址反馈给网 关的方式。 其中， 所述网关进行设备识别、 管理和服务所需的模块和文件 包括网关所需的接入协议模块、 管理模块、 设备控制模块、 控制界面和服 务模块和文件。 同时， 设备识别服务单元还会反馈设备基本信息描述文件 给网关。
认证服务单元配置为对终端设备的厂商进行认证， 通过认证的厂商可 以注册标签信息、 注册网关所需模块或文件下载地址以及上传网关所需模 块或文件到公共下载服务器， 认证成功后才能进行注册、 上传和下载服务。
标签信息注册服务单元配置为对终端设备的标签信息进行注册。 注册 的标签信息将作为对终端设备进行识别的唯一依据。
地址注册服务单元配置为对网关进行设备识别、 管理和服务所需的模 块和文件的下载地址进行注册。 由于一些对终端设备接入或管理的模块和 文件， 是由各个厂商提供和维护的， 因此， 厂商通过此项单元提供的地址 注册服务将模块或文件的下载地址注册到能力开放平台， 能力开放平台再 将注册的下载地址反馈给需要的网关。
上传服务单元配置为提供对网关进行设备识别、 管理和服务所需的模 块和文件的上传服务。 上传的模块和文件统一部署到公共下载服务器， 并 由能力开放平台将模块和文件的下载地址反馈给需要的网关。
图 2为本发明方法实施例的实现流程示意图， 如图 2所示， 该方法包 括以下步骤：
步骤 101， 网关对设备 A授权。 这里， 授权的设备 A可以是带摄像头的终端设备， 如具有条形码读取 功能、二维码读取功能或 RFID标签读取功能的带摄像头的手机。授权成功 后设备 A发送给网关的条形码、 二维码或 RFID等标签信息将作为网关下 载所需模块或文件的依据； 对于未授权设备或已撤销授权的设备发送的标 签信息， 网关只作为普通数据处理。
这里， 网关对设备 A的授权实现可以通过：
方式一， 设备 A上预先安装授权应用程序， 授权流程可以由网关的设 备授权模块或设备 A的授权应用程序发起。 以设备 A发起授权为例， 设备 A发送授权请求给网关同时携带设备 A基本信息； 网关设备授权模块根据 设备 A的请求信息判断是否同意授权； 如果同意授权则网关设备授权模块 发送授权确认信息同时携带会话密钥； 设备 A接收到网关发送的授权确认 信息后授权流程结束， 后续将发送采用会话密钥加密的标签数据。 在授权 有效期内设备 A发送给网关的标签信息将作为网关下载所需模块或文件的 依据。
方式二， 要求设备 A能够提供标签读取服务， 网关选择设备 A作为授 权设备； 网关设备授权模块记录授权关系和授权信息并调用设备 A标签读 取服务； 设备 A接收到网关请求后会将读取的标签信息发送给网关； 在授 权有效期内设备 A发送给网关的标签信息将作为网关下载所需模块或文件 的依据。
步骤 102， 设备 A读取设备 B的条形码、 二维码或 RFID标签信息并 将信息发送给网关。
步骤 103， 网关根据设备 B的标签信息调用能力开放平台的设备识别 服务。
这里， 网关接收到设备 B的标签信息后将知道设备 B为需要接入、 管 理、 控制或服务的设备。 网关调用外网的能力开放平台的设备识别服务并 将设备 B的标签信息和网关自身信息发送给能力开放平台。
步骤 104， 能力开放平台反馈网关所需的模块或文件下载地址。
这里， 能力开放平台根据网关发送的设备 B标签信息和网关信息匹配 网关所需的模块或文件。 能力开放平台反馈的内容包括： 网关实现设备 B 接入的协议模块或文件的下载地址、 实现设备 B管理和控制的模块或文件 下载地址、 实现对设备 B控制的控制界面所需的模块或文件下载地址、 为 设备 B提供服务所需的模块或文件的下载地址以及设备 B的基本信息描述 文件。
这里， 能力开放平台优选采用反馈下载地址而非直接反馈所需模块或 文件的好处是： 一方面考虑到网络流量因素， 是否下载以及何时下载将由 网关决定； 另一方面考虑到实际的应用场景中某些模块是由终端设备厂商 提供和维护， 设备厂商通过将下载地址注册到能力开放平台然后由平台对 外统一提供服务， 平台根据网关请求将下载地址反馈给网关， 网关再从厂 商的服务器中下载所需模块或文件。
步骤 105， 网关根据能力开放平台反馈的地址下载所需的模块或文件。 这里， 网关根据能力开放平台反馈的下载地址下载所需的模块或文件 (如步骤 104中涉及能力开放平台反馈的内容所述， 此处不做赘述）。 网关 可以保存能力开放平台反馈的下载地址、 从外网下载的软件模块或文件， 网关可以优先采用保存的下载地址、 软件模块或文件实现设备的接入、 管 理、 控制或服务。
步骤 106， 网关加载下载的模块或文件， 实现对设备 B的接入、 管理、 控制和服务。
这里， 网关实现设备接入的方式包括：
方式一， 网关加载下载的设备接入协议模块或文件后， 如果协议中包 括握手 （设备探寻）协议则网关通过主动发送握手请求（可每隔一段时间 发送一次握手请求）或监听设备发出的握手请求再根据协议完成握手过程 即可实现设备接入。
方式二， 对于协议中不含有握手 （设备探寻） 过程的， 当网关接收到 设备发出的数据包后网关根据收到的数据包协议头进行与下载的接入协议 的自动适配或者网关根据数据包的底层协议信息（例如 MAC地址）与下载 的设备基本信息描述文件进行接入协议的自动适配。如果读取的 RFID标签 信息中包括底层协议信息（例如 MAC地址 )也可根据接收到的数据包的底 层协议信息和 RFID中读取的信息进行协议的自动适配。
方式三， 对于上述两种方式不能进行协议自动适配或适配后匹配出多 个接入协议的， 网关在接收到设备发出的数据包后在界面中显示为未识别 设备， 此时用户只需将之前下载的模块（模块在界面中显示信息包括设备 基本信息， 例如厂商， 产品名称等） 与未识别设备匹配即可， 匹配方式可 以是将下载的模块图标拖动到未识别设备上。 设备匹配后网关可以通过下 载的模块和记录的通信地址对设备进行管理和控制等。
图 3为本发明网关一实施例的组成结构示意图， 该网关配置为通过对 已接入网关的终端设备进行授权， 由已接入网关的终端设备读取未接入网 关的终端设备的标签信息， 实现对未接入网关的终端设备的识别。 其中， 已接入网关的终端设备具备标签信息读取能力。 具体的， 网关包括以下模 块：
设备授权模块： 网关的设备授权模块配置为授权外部设备作为网关的 标签信息采集设备， 设备授权模块还配置为实现设备的授权、 撤销授权并 维护授权信息。
设备识别模块： 网关的设备识别模块配置为请求能力开放平台的设备 识别服务并将获得的终端标签信息和网关自身信息发送给能力开放平台。
无线模块： 网关通过无线模块与被授权设备交互， 包括通过无线模块 实现设备的授权和设备条形码、二维码或 RFID标签信息的接收。无线模块 一般包括 Wifi、蓝牙、 Zigbee、 RF433、 RF779或红外等多种无线通讯方式。
可扩展框架： 网关通过可扩展框架动态加载所下载的模块来实现功能 扩展。可扩展框架可以选用 OSGI框架等。其中，所述 OSGi是 Open Service Gateway Initiative的缩写， 该技术是面向 Java的动态模型。 OSGi框架定义 了一个标准的、 面向组件的计算环境， 软件组件（bundle )可以从运行中被 安装、升级或者移除而不需要中断设备的操作。采用此 OSGi框架可以通过 从下载服务器中下载所需的 bundle从而实现终端设备的接入、 管理、 控制 和服务。
下载模块： 网关下载模块根据能力开放平台反馈的下载地址从外网下 载实现设备接入、 管理、 控制和服务所需的软件模块或文件。
下载管理模块： 下载管理模块管理从外网下载的软件模块或文件， 下 载管理模块可以根据策略保存或删除所下载的模块或文件。 例如根据设备 连接情况或下载的软件模块的使用情况决定是否删除相应模块或文件。
外网接口： 配置为连接外部网络， 一般地配置为连接互联网。
采用本网关的好处是： 网关采用了对具有标签读取能力的设备授权来 实现其它设备条形码、二维码或 RFID标签信息的获取，对网关改动小并且 充分利用网络中已有的设备（如手机） 来获取其它设备标签信息， 能更好 的降低网关的实现成本， 从而有利于其推广实施。 更进一步的， 利用本发 明实施例的网关所提出的方法不需要对现有终端设备进行改造， 需要的只 是设备上都会有的条形码、二维码或 RFID标签， 然后网关通过已有的无线 模块对手机等设备授权来实现设备标签信息的获取。 采用本发明实施例， 对现有设备改动小， 使得本发明实施例具有较高可行性； 从易用性考虑用 户只需要拿通过授权的手机等读取某个设备的条形码、二维码或 RFID标签 信息就能实现此设备的接入、 管理、 控制和对设备提供服务， 用户使用非 常方便。
图 4为本发明网关另一实施例的组成结构示意图， 该网关配置为读取 未接入网关的终端设备的标签信息， 实现对未接入网关的终端设备的识别。 其中， 网关自身具备标签信息读取能力。 具体的， 该网关包括以下模块： 带摄像头的标签读取模块： 网关中包括一个带摄像头的标签读取模块， 此模块可以读取设备的条形码和二维码信息并将信息通过天线发送给网关 的无线模块。

以下为本发明实施例的一个物联网家庭应用的应用实例。
在物联网家庭应用中， 家庭内已经部署了网关并且网关与外网相连， 家庭成员拥有的手机已经连接到网关。 这时家庭内新添置的冰箱采用的是 厂家自有协议， 而网关支持中国电信的 MDMP协议， 网关需要能实现冰箱 的接入、 能够对其进行管理和控制并支持冰箱到 MDMP协议的转换从而实 现冰箱与家里其它家电的通信， 包括以下步骤：
步骤 301， 网关对手机授权。
手机通过 Wifi与网关相连； 预先在手机上安装需要的应用软件， 在软 件中选择授权选项， 手机将向网关发送授权请求包并附带手机型号信息； 网关接收到授权请求包后在界面中显示接收到授权请求， 同时显示发起授 权请求的设备信息 （手机型号） 并询问是否同意授权； 用户在网关人机界 面中选择同意授权； 网关记录授权信息并反馈授权成功消息和会话密钥给 手机； 手机接收到授权确认信息后整个授权流程结束。 手机被授权后其发 送给网关的设备标签信息将作为网关下载所需模块的依据， 而对于未授权 设备或已撤销授权的设备其发送给网关的标签信息网关只作为普通数据处 理。
步骤 302， 手机读取需要接入的冰箱二维码并将二维码信息发送给网 关。
选择手机应用软件上的扫描二维码选项并将手机摄像头靠近冰箱的二 维码。 手机通过摄像头读取冰箱上的二维码信息并将信息通过前面的会话 密钥加密后发送给网关。
步骤 303，网关根据获得的冰箱二维码信息从能力开放平台获得所需模 块下载地址。 网关收到冰箱二维码信息调用能力开放平台发送设备识别服 务并将冰箱二维码信息和网关设备型号发送给能力开放平台。
步骤 304，能力开放平台根据冰箱二维码信息和网关型号匹配网关所需 的软件模块并将软件模块的下载地址反馈给网关。
反馈的信息具体包括： 冰箱所采用协议的设备接入模块下载地址、 基 于冰箱所采用协议的设备管理模块下载地址、冰箱所采用协议到 M2M终端 监测控制协议（MDMP， M2M Device Management Protocol )转换模块的下 载地址、 由冰箱厂商提供的冰箱控制界面下载地址和冰箱基本信息描述 XML文件。
步骤 305， 网关从下载服务器中下载所需模块。 网关根据能力开放平台 反馈的下载地址分别从公共下载服务器和厂商维护的下载服务器中下载所 需模块。 网关从公共下载服务器中下载设备接入模块和到 MDMP协议的转 换模块， 从厂商提供的下载服务器中下载冰箱管理 /控制模块和控制界面。
步骤 306， 网关加载所下载的模块实现冰箱的接入、管理、控制和服务。 网关所下载的模块采用 bundle封装。 网关通过自身的 OSGI框架加载所下 载的 bundles 实现网关功能的扩展。 bundle加载完成后网关通过设备接入 bundle发送设备探寻包， 冰箱接收到探寻包后反馈相应信息完成通信握手。 用户可以通过网关上加载的冰箱控制界面 bundle对冰箱进行控制， 包括设 置温度和时间等。
步骤 307，在手机应用程序中选择家电控制功能并选择需要控制的冰箱 设备。 网关将所选择冰箱的控制界面 bundle发送给手机。 现在手机上显示 的冰箱控制界面与网关显示器上的显示界面相同。 用户可以通过手机上的 冰箱控制界面对冰箱的温度和时间进行设置， 用户在手机的冰箱控制界面 上的操作消息将首先发送给网关并由网关的冰箱控制模块转换为对冰箱的 控制命令， 最终通过网关将控制命令发送给冰箱。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。 工业实用性
