Low-power-consumption transmitter based on narrow-band Internet-of-things

Abstract

The invention discloses a low-power-consumption transmitter based on the narrow-band Internet-of-things, and belongs to the field of transmitters. The low-power-consumption transmitter comprises a single-chip microcomputer module; a stabilized voltage supply module which is connected with the single-chip microcomputer module; a data acquisition module which is connected with the single chip microcomputer module; a data acquisition power supply module which is connected with the data acquisition module; a data acquisition power supply switch module which is connected with the data acquisition power supply module; a wireless module which is connected with the single-chip microcomputer module; a state indication module which is connected with the single chip microcomputer and the wireless module; a power supply module which is respectively connected with the stabilized voltage supply module, the data acquisition module, the data acquisition power supply switch module, the wireless moduleand the state indication module; and a power supply voltage detection module which is respectively connected with the power supply module and the single-chip microcomputer module. The beneficial effects of the low-power-consumption transmitter are that the system is low in power consumption and long in service life; alarm data can be uploaded in time, the working state of the transmitter can be indicated, and the state of the transmitter can be known in real time; the wireless transmission distance is long, the connection number is large, and the system is widely applied to fire-fighting remote data transmission.

Description

technical field [0001] The invention relates to the field of transmitters, in particular to a low-power transmitter based on narrowband Internet of Things. Background technique [0002] Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180kHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. NB-IoT is an emerging technology in the IoT field, which supports cellular data connections of low-power devices in wide area networks, also known as low-power wide area networks (LPWAN). NB-IoT supports efficient connection of devices with long standby time and high network connection requirements. It is said that NB-IoT device battery life can be improved by at least 10 years, while also providing very comprehensive indoor cellular data connection coverage. [0003] At present, ...
