Abstract

The invention discloses an ultra-low power consumption multi-mode internet of things wireless module. A GPRS module is connected with a MCU control unit through a UART, the MCU control unit performs control, command or data interaction on the GPRS module through an AT instruction or an instruction set of the GPRS module; the power-off, the turn-off and the dormancy on the GPRS module by the MCU control unit are performed through the GPIO; an LORA module is connected with the MCU control unit through an UART, the MCU control unit performs control, command and data interaction on the LORA modulethrough the AT instruction or according to a support command table of the LORA module; a NB-IOT module is connected with the MCU control unit through the UART or IIC; an EMTC module is connected withthe MCU control unit through a PCM interface and a SPI interface; and the Sigfox module is connected with the MCU control unit through the UART. The multi-mode internet of things module formed in theinvention can satisfy various application scenes.

Description

technical field [0001] The present invention relates to the field of Internet of Things. More specifically, the present invention relates to an ultra-low power consumption multi-mode Internet of Things wireless module. Background technique [0002] Most of the networking methods of the Internet of Things network are star networks or ad hoc networks. Usually, the nodes are composed of sensors or terminals + wireless transmission modules. The core of its networking is to connect with gateways or access points through wireless transmission modules. The access point connects to the server or self-organizing network. Most of the mainstream IoT modules currently on the market are single-mode LORA or NB-IOT or GPRS modules. The LORA module is usually connected to the LORAWAN network or a private network composed of LORA, but the disadvantage is that the gateway and server must be redeployed. Contents of the invention [0003] The purpose of the present invention is to provide ...
