Edge computing gateway based on narrowband internet of things

Abstract

The invention provides an edge computing gateway based on a narrowband internet of things. The edge computing gateway comprises a power supply module, and a wireless data communication module, a processing module, a narrowband internet of things communication module and a storage module which are respectively connected with the power supply module. The edge computing gateway receives data collected by a data acquisition terminal through a narrowband wireless remote transmission technology, processes, summarizes and encrypts the data and transmits the data to a remote monitoring center througha wireless network. The edge computing gateway and the data acquisition terminal are in encrypted transmission through bidirectional AES128. The edge computing gateway further comprises an active datapolling mechanism and an offline monitoring mechanism. The edge computing gateway makes a centralized computing mode of an Internet of Things system converted into an edge computing mode, and has theadvantage of reasonably distributing computing power, reducing the number of gateways, reducing cost and increasing profits.

Description

【Technical field】 [0001] The invention relates to the field of communication technology, in particular to an edge computing gateway based on narrowband Internet of Things. 【Background technique】 [0002] At present, the basic functions of the IoT gateway include data collection, transparent transmission, monitoring, and device control. The basic process is to connect devices through standard physical interfaces, analyze protocols for data collection, and use standard protocols such as MQTT to transparently transmit data to the cloud platform. The cloud platform issues instructions to control devices according to predetermined rules. Therefore, the current IoT gateway basically does not have the functions of edge computing and data storage, and only transparently transmits data, which cannot meet the high-frequency data collection, real-time data processing, and low-latency feedback response capabilities required by the IoT. [0003] Existing gateways are mainly designed for...

Problems solved by technology

Most of the existing acquisition equipment is connected to the collector by means of wired modbus485 communication, which requires long-distance cable laying, and the electric well of the pipe gallery needs to be drilled and slotted, and the construction cost is huge

Existing wireless products mostly use 2.4G or Sub-Ghz fsk ask communication solutions. Although the problem of building holes and slots is solved, the communication distance of traditional wireless methods is limited, and it cannot achieve wide-area coverage and compatibility with low-power front-ends.
