异构无线网络的物联网网关及控制方法 Things heterogeneous wireless network gateway and a control method

技术领域 FIELD

[0001] 本发明涉及数据通信的技术领域,具体说是一种在异构无线网络环境下,由层叠式结构的多层网关构成,实现物与物之间的有效互联的异构无线网络的物联网网关及控制方法。 [0001] The present invention relates to the field of data communications, in particular to a heterogeneous wireless network environment, a gateway of a multilayer laminated structure, effective interconnection between heterogeneous wireless networks and the object thereof network gateway and a control method thereof.

背景技术 Background technique

[0002] 物联网网关是物联网系统平台的重要组成部分,也是实现数据透传、解决多种异构技术、对前端感知网络控制组网的核心部件。 [0002] IOT gateway is an important part of the platform of things, but also to realize transparent transmission of data, to solve a variety of heterogeneous technologies, the perception of the distal end of the core network components of the network control.

[0003] 物联网是指将各种传感设备与互联网结合起来而形成的一个巨大网络,可以使所有的产品与网络连接,最终实现人与物,物与物之间的信息传递。 [0003] IOT refers to various sensing devices and the Internet combine to form a huge network, can make all of the products connected to the network, and ultimately the transmission of information between objects, things and objects. 物联网实质是以无限传感网络技术和RFID技术为感知,实现所有产品的互联互通。 Things essence is unlimited sensor network technology and RFID technology to sense, to achieve interoperability of all products. 物联网具有感知、可靠传递、智能处理特点,是继计算机、互联网、移动通信之后的信息技术。 Things have perceived, reliable delivery, intelligent processing characteristics, it is the second computer, the Internet, a mobile communication information technology.

[0004] 物联网系统划分为三个层次:感知层、网络层、应用层,并依此概括地描绘物联网的系统架构。 [0004] IOT system is divided into three levels: perception layer, network layer, application layer, and so generally depicted IOT system architecture. 感知层解决的是人类世界和物理世界的数据获取的问题。 Perception layer to solve the problem is the human world and the physical world data acquired. 可进一步划分为两个子层,首先是通过传感器、数码相机等设备采集外部物理世界的数据,然后通过RFID、条码、工业现场总线、蓝牙、红外等短距离传输技术传递数据。 May be further divided into two sub-layers, a first external physical world data collected by the sensor, and digital cameras, then the RFID, barcode, industrial field bus, Bluetooth, infrared and other short-range transmission technique to transfer data. 也可以只有数据的短距离传输这一层,特别是当仅传递物品的唯一识别码的情况。 It may be only a short distance data transmission of this layer, especially when the unique identification code is transmitted only in the case where the article. 在实际上,这两个子层有时很难以明确区分开。 In fact, these two sub-layer is sometimes difficult to separate clearly distinguished. 感知层所需要的关键技术包括检测技术、短距离有线和无线通信技术等。 The key technologies required for perception layer comprises detecting technologies, short-range wireless communications technology and wired.

[0005] 网络层解决的是感知层所获得的数据在一定范围内,通常是长距离的传输问题。 [0005] network layer addressed is aware layer data obtained within a certain range, usually long-distance transmission problems. 这些数据可以通过移动通信网、国际互联网、企业内部网、各类专网、小型局域网等网络传输。 These data can be mobile communication network, the Internet, intranets, all kinds of special network, and other small local area network transmission. 特别是当三网融合后,有线电视网也能承担物联网网络层的功能,有利于物联网的加快推进。 Especially when triple play, cable television network can assume the function of the network layer of the Internet of Things, in favor of speeding up things. 网络层所需要的关键技术包括长距离有线和无线通信技术、网络技术等。 The key technologies required for the network layer include wired and wireless long-range communication technology, network technology.

[0006] 应用层解决的是信息处理和人机界面的问题。 [0006] The application layer is to solve the problem of information processing and human-machine interface. 网络层传输而来的数据在这一层里进入各类信息系统进行处理,并通过各种设备与人进行交互。 Transmission of data from the network layer all kinds of information into the system for processing at this level where, through a variety of devices and interact with people. 这一层也可按形态直观地划分为两个子:一个是应用程序层,进行数据处理,它涵盖了国民经济和社会的每一领域,应用程序层包括电力、医疗、银行、交通、环保、物流、工业、农业、城市管理、家居生活等领域, 同时可用于政府、企业、社会组织、家庭;另一个是终端设备层,用于提供人机界面,物联网虽然是“物物相连的网”,但最终是要以人为本的,最终还是需要人的操作与控制,不过这里的人机界面已远远超出现时人与计算机交互的概念,而是泛指与应用程序相连的各种设备与人的反馈。 This layer forms can also be visually divided into two sub-: one is the application layer, data processing, it covers every field of the national economy and society, the application layer includes electricity, health care, banking, transportation, environmental protection, logistics, industry, agriculture, urban management, home life, etc., and can be used in government, enterprises, social organizations, family; the other is a terminal device layer providing human-machine interface, although things are "material objects connected to the network "but ultimately it is people-oriented, and ultimately need to operate and control people, but here the man-machine interface concept far beyond current human-computer interaction, but refers to a variety of devices and applications connected with people's feedback.

[0007] 在各层之间,信息不是单向传递的,可有交互、控制等,所传递的信息多种多样,这其中关键是物品的信息,包括在特定应用系统范围内能唯一标识物品的识别码和物品的静态与动态信息。 [0007] In between the layers, not one-way transmission of information, there may be interactive, control, information is transmitted is varied, which is the key information items, including items that uniquely identifies a particular application within the scope of the system static and dynamic information identification code and the article. 此外,软件和集成电路技术都是各层所需的技术。 In addition, software and integrated circuit technologies are layers of technology required.

[0008] 物联网网关是物联网应用中的核心设备,物联网网关同时配备感知网络接口和广域IP网络接口,负责在感知网络和各种广域IP网络间进行数据转发。 [0008] Things networking applications gateway is the core equipment, networking gateway equipped with a network interface and WAN-aware IP network interface is responsible for forwarding data-aware networks and wide-area IP network between. 网关通常也会提供对前端感知网络的管理功能,并将感知网络管理API发布给远方管理平台。 Gateway will usually provide the front-end-aware network management functions, and aware network management API issued to the remote management platform. [0009] 但是,如上所述的已有技术中存在如下的不足点: [0009] However, the prior art described above has the following shortcomings point:

[0010] 现场网络种类繁多、制式不一,各种现场网络各不相同,网关的硬件能力和软件API不存在统一的制式标准,造成下层网络的复杂性,使物联网的开发和使用都具有较大难度并且需要投入较多的成本。 [0010] The field network a wide range of different formats, a variety of different network site, a gateway hardware and software capabilities unified standard API standards exist, the resulting complexity of the underlying network, the development and use of things have more difficult and requires more investment costs. 现有的物联网由于受到前端感知设备的传输方式、协议的严格限制,无法实现物与物之间的有效互联。 Existing things due to the perceived front-end transmission equipment, the strict limits of agreement, can not achieve effective interconnection between things and things. 由于受到感知网络接入能力的限制,区域范围内无法实现对感知网络的自组网,所以不具备SMS、USSD、TCP、UDP等通信协议能力的前端感知节点无法接入物联网平台。 Due to limited aware network access capability, can not be achieved on a regional network-aware ad hoc network, the nodes do not have the perception distal SMS, USSD, TCP, UDP communication protocol such things can not access the capabilities internet.
