清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明实施例公开了一种物联网通信模式的切换控制方法,摈弃传统的物联网单一通信模式,实现灵活的通信模式切换控制,满足终端设备更高的通信需求。本发明实施例相应地公开了一种物联网通信模式的切换控制系统。
在介绍本发明实施例之前,先简单介绍一下本发明一些实施例公开的物联网架构。如图1所示,图1为本发明一些实施例公开的物联网架构示意图;图1所示的物联网架构按照功能划分可以包括终端设备层、接入节点层以及汇聚层三个层。其中,终端设备层可以包括海量规模的终端设备,例如视频监控系统、自动取款机、湿度计、烟感器、通风设备、雨量传感器、灌溉阀等等;接入节点层可以包括网络连接的大量的边缘接入节点,边缘接入节点可以包括路由器、中继器、接入点等设备,本发明实施例不作限定;边缘接入节点可以使用任何标准的组网协议,而且边缘接入节点可以在不同的网络制式之间实现数据解析;汇聚层可以包括汇聚单元,汇聚单元可以对接入节点层的各个边缘接入节点进行高层管理,从而实现数据传输频率、网络拓扑以及其他组网功能的控制;汇聚单元不仅可以对海量终端设备产生的物联网数据进行分析和决策,还可以通过发指令去获取信息或者配置终端设备参数(此时数据的传输指向终端设备);汇聚单元还可以引入各种业务,从大数据到社交网络、甚至从社交工具“点赞”到天气分享等。在图1所示的物联网架构中,每一个边缘接入节点可以为其网络覆盖范围内的海量终端设备提供物联网数据收发服务,其中,每一个边缘接入节点网络覆盖范围内的每一个终端设备可以内置有无线通信协议的无线通讯模块或者以传统组网协议直接与互联网连接的传统通讯模块,这使得每一边缘接入节点可以通过网络通讯方式与每一个终端设备进行无线通讯。在图1所示的物联网架构中,终端设备内置的无线通讯模块在生产时,可以输入上频点470MHz,下频点510MHz,这样无线通讯模块可以自动将通讯频段定义为470MHz~510MHz,以符合中国SRRC标准的规定;或者,也可以输入上频点868MHz,下频点908MHz,这样无线通讯模块可以自动将通讯频段定义为868MHz~908MHz,以符合欧洲ETSI标准的规定;或者,可以输入上频点918MHz,下频点928MHz,这样无线通讯模块可以自动将通讯频段定义为918MHz~928MHz,以符合美国FCC标准的规定;或者,无线通讯模块的通讯频段也可以定义为符合日本ARIB标准或加拿大IC标准的规定,本发明实施例不作限定。在图1所示的物联网架构中,终端设备可以采用频分复用(Frequency Division Multiple Access,FDMA)、跳频(Frequency-Hopping Spread Spectrum,FHSS)、动态时分复用(Dynamic Time
Division Multiple Access,DTDMA)、退避复用(CSMA)相结合的方法来解决干扰问题。传统通讯模块通过设置传统组网协议,如传输控制协议/互联网协议(Transmission Control Protocol/Internet Protocol,简称TCP/IP)。
下面将从图1所示的物联网架构的角度出发,并结合具体实施例对本发明技术方案进行详细说明。
实施例一
请参阅图2,图2为本发明实施例公开的物联网通信模式的切换控制方法的流程示意图;如图2所示,一种物联网通信模式的切换控制方法可包括:
201、边缘接入节点接收汇聚单元下发的通信配置信息;该通信配置信息包括设备标识、第一通信接口设置参数和第二通信接口设置参数。
本发明实施例中的第一通信接口设置参数用于设置第一通信接口,第一通信接口是通过无线通信协议实现的、且采用免授权频段进行数据传输。第二通信接口是通过传统TCP/IP协议实现的、且采用授权频段进行数据传输。
可以理解的,在物联网中部分终端设备采集的数据对实时性和可靠性要求较高,同时数据比较大,也需要较高的带宽,适用于“小”数据且安全性较低的免授权频段的无线通信模式并不适合传输这些数据。举例来说,物联网中的视频监控系统,采集的数据都是视频文件,数据比较大,而且也对数据传输过程中的安全性提出要求,因此,这类终端设备不同于湿度计只用于上传表征土壤湿度的“小”数据。但是,这类终端设备同时也存在收发一些简单的指令或者数据,如果考虑传统的TCP/IP协议,显然又会造成资源浪费,而且也会增加成本,因此,在本发明中针对这类终端设备设置第一通信接口和第二通信接口,可以根据实际需求选择不同的通信接口进行通信,以满足数据在可靠性、实时性和带宽上的不同需求。
边缘接入节点接收汇聚单元下发的通信配置信息之前,本发明实施例还包括:边缘接入节点接收汇聚单元下发的数据传输控制信息,该数据传输控制信息包括数据采集时间和设备标识;边缘接入节点将数据传输控制信息中的数据采集时间发送给匹配设备标识的终端设备;终端设备接收数据采集时间并保存。通过该实施方式,对汇聚单元指定的终端设备设置数据采集时间,以控制终端设备在该数据采集时间周期性采集数据并上报,实现汇聚单元对终端设备的管理功能。
202、边缘接入节点将通信配置信息中的第一通信接口设置参数和第二通信接口设置参数发送给匹配设备标识的终端设备。

标识,终端设备在监测到该广播消息时,从广播消息中提取该设备标识,如果该设备标识为自身对应的设备标识,从广播消息中获取该第一通信接口设置参数和第二通信接口设置参数。
进一步地,广播消息中的第一通信接口设置参数和第二通信接口设置参数被加密打包成一个数据包,终端设备从广播消息中提取该设备标识,如果该设备标识为自身对应的设备标识,终端设备根据预置的解密算法解密以获得第一通信接口设置参数和第二通信接口设置参数,以提高数据安全性。

作为一种可选的实施方式,终端设备调用第一通信接口将第一数据包发送给边缘接入节点具体包括:终端设备调用第一通信接口,在免授权频段上确定目标传输频段;在目标传输频段上与边缘接入节点建立通信连接,以及基于建立的通信连接将第一数据包上报给边缘接入节点。
