Embodiment 1

[0031]The gateway adopts a three-layer model, including connection layer, core layer and wide area network communication layer. Among them, the connection layer is used to connect other ad hoc networks in the environment, so that it can access the gateway and communicate with the core layer; the core layer connects the connection layer and the WAN communication layer, and communicates from the connection layer to the WAN communication layer The received data undergoes protocol fusion, protocol conversion, and data processing; the WAN connection layer is responsible for accessing the telecommunications network and communicating with the server.

[0032] Such as figure 1 As shown, the IoT multifunctional gateway suitable for NB-IoT (Narrowband Internet of Things) consists of an interface module, a conversion module, a main control module, and an NB-IoT module; it provides an expandable USB host interface and an Ethernet interface , 4 485 interfaces, 2 232 interfaces and CAN int...

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 ...
