Abstract

The invention provides a narrowband Internet of Things NB-IOT module, a control method and an MCU, and relates to the technical field of communication. The control method comprises the following steps: sending network state information of an NB-IOT module to a micro control unit MCU; and under the condition that the network state information meets a preset condition, if the NB-IOT module is not connected with the network equipment within a preset duration, the MCU controlling the NB-IOT module to disconnect a power supply or be in a flight mode. According to the embodiment of the invention, the network state information of the NB-IOT module is sent to the MCU, and if the NB-IOT module is not connected with the network equipment within the preset duration under the condition that the network state information meets the preset condition, the MCU controls the NB-IOT module to disconnect the power supply or be in the flight mode, so that the electric quantity of the battery can be saved, and normal operation of the system is ensured.

Description

technical field [0001] The invention relates to the field of communication technologies, and in particular, to a narrowband Internet of Things NB-IOT module, a control method and an MCU. Background technique [0002] Today's Narrow Band Internet of Things (NB-IOT) devices generally use lithium polymer batteries, dry batteries, lithium manganese batteries, lithium sub batteries and other batteries for power supply. Since NB-IOT is built on the cellular network, the bandwidth The bandwidth is 180KHz, and is deployed in a Global System for Mobile Communication (GSM) network, a Universal Mobile Telecommunication System (UMTS) network, or a Long Term Evolution (Long Term Evolution, LTE) network. When the above battery passes the DC-DC DC-DC (Boost DC-DC or Buck DC-DC) chip or Low Dropout Voltage Regulator (LDO) chip; or directly supplies power to the NB-IOT chip Or NB-IOT module, because it is a cellular network system, the device is powered on to search the network and the netw...
