Low-power-consumption electronic tag based on UWB method and positioning method

The invention discloses a low-power-consumption electronic tag based on a UWB method and a positioning method, the electronic tag is composed of a radio frequency transceiver module, an MEMS module, an ARM processor module and a power supply module, a low-power-consumption technology is used at the same time, and the ARM processor module controls the radio frequency transceiver module and the MEMSmodule to be in a sleep state for a long time. The radio frequency transceiving module and the MEMS module are periodically awakened to enter a normal working state, so that the power consumption isreduced; electronic tags are deployed in an ultra-wideband mode in a positioning system, signal flight time is calculated to complete data communication between the tags and a base station, multiple groups of distance measurement results are uploaded to a server, and finally, the server is processed by using a least square method to store data to complete ultra-wideband positioning.
