Network architecture and networking method applied to Internet of Things

Abstract

The invention provides a system network architecture and a device applied to data collection and data transmission in the Internet of Things. The architecture comprises three layers of networks consisting of a data collection network, a data transmission network and a core network, wherein the data collection network is composed of a plurality of data collection sub-networks, and each data collection sub-network is composed of a plurality of wireless communication sub-node and a relay; the data transmission network is composed of a plurality of transmission sub-networks, and each transmissionsub-network is composed of a plurality of wireless terminals and a wireless base station; the data collection network and the data transmission network are connected via an interface protocol in a concentrator between the wireless relay and the wireless terminal; the core network is composed of a gateway, a switch, a router, a data management server and a network management server; the main functions of the core network comprise network management and data management; and the core network and the transmission network are connected via an interface between the gateway and the wireless base station. The scheme provided by the invention has the characteristics of being flexible to network, strong in network adaptation and high in network efficiency.

Description

Technical field [0001] This application relates to a network architecture field and device, and in particular to a network architecture for the Internet of Things. Background technique [0002] With the development of intelligence and informatization, in the era of the Internet of Everything, there is a large demand for low-cost, high-efficiency data collection, transmission and management system networks. However, the existing technology can provide solutions that are either expensive For example, if the public network 3G / 4G or NB-IOT is adopted, although the network performance is good, each communication node needs to pay a high traffic fee to the operator every year, and the current industry's more popular low-power wide area network standard Lora, communication The network solution also has a low transmission rate, and it is not suitable for a short-distance high-speed application. The traditional wifi and Zigbee technologies have the problem of high power consumption. There...

[0002] With the development of intelligence and informatization, in the era of the Internet of Everything, there is a large demand for low-cost and high-efficiency data collection, transmission and management system networks. However, the solutions that existing technologies can provide are either costly , such as the use of public network 3G / 4G or NB-IOT, although the network performance is good, but each communication node needs to pay a high traffic fee to the operator every year, and currently the industry's more popular low-power wide area network standard Lora, communication The network solution has a low transmission rate, and it is not suitable for a short-distance high-speed application. However, traditional wifi and Zigbee technologies have the problem of high power consumption. Therefore, how to provide a low-cost, low-power, High-speed data collection, transmission and management network solutions are imminent
