Internet of things multifunctional gateway based on NB-IoT

Abstract

The invention provides an Internet of things multifunctional gateway based on NB-IoT, and aims at solving the communication problem of two or more wireless or wire sensing communication networks and the NB-IoT. The multifunctional gateway comprises an interface module, a conversion module, a master control module, a NB-IoT module, wherein the interface module provides a module interface with other wireless or wire sensing network; the conversion module realizes the level matching and conversion between the interface module and the master control module; the master control module provides the protocol adaption, the protocol conversion, and the data processing of each communication network through a microprocessor; the NB-IoT module accesses to a communication network to communicate with the server through an operator base station. The microprocessor is used as the core component to connect with other network module through a standard extensible interface, the information exchange between other networks is established in a bus way, and the communication with the server is performed through a mobile operator base station by the NB-IoT module.

Description

technical field [0001] The invention relates to the field of wireless gateways, in particular to a multifunctional gateway based on narrowband internet of things. Background technique [0002] Wireless sensor network is a task-oriented wireless self-organizing network system, usually composed of several data aggregation nodes. Currently commonly used technologies for wireless networking include: short-distance communication technologies such as Zigbee, WiFi, and Bluetooth, LoRa, and wide area network communication technologies such as NB-IoT that have just emerged. Different wireless communication technologies have their own advantages and limitations in use: LoRa transmits on unlicensed spectrum, and the reliability and security of transmission are not enough to build a larger-scale Internet of Things system; WIFI, Zigbee, Bluetooth, etc. The ad hoc network coverage achieved by short-distance communication technology is not strong, and there is a lack of unified operation ...

AI Technical Summary

Problems solved by technology

Different wireless communication technologies have their own advantages and limitations in use: LoRa transmits on unlicensed spectrum, and the reliability and security of transmission are not enough to build a larger-scale Internet of Things system; WIFI, Zigbee, Bluetooth, etc. Short-distance communication technology, the ad hoc network coverage achieved by it is not strong, and there is a lack of unified operation and maintenance standards in use

However, due to the fact that terminals of different standards of various wireless communication technologies cannot be interconnected, the ad hoc network formed by traditional wireless communication technologies cannot communicate with NB-IoT
