Abstract

The invention discloses a low-power multi-mode positioning label which comprises at least one radio frequency module, which supports multiple radio frequency modes including at least one low-power narrow-band transmission mode, a micro-controller module, an electric quantity monitoring module which is used for monitoring the residual electric quantity condition of the electric quantity monitoringmodule and connected with the micro-controller module, and an accelerometer module which is used for monitoring that the accelerometer module is in a motion state or a static state and connected withthe micro-controller module. The positioning label uses an accelerometer to judge whether the label is in a motion state, and broadcasting collected positioning nodes and sending acquired informationcan be done frequently only in the motion state, so that a large amount of power consumption is reduced. Due to the fact that the positioning label adopts an emerging low-power narrow-band mode to transmit data, the transmission power consumption is low, and the long-standing problem that the battery life of the positioning label is short is solved.

Description

technical field [0001] The invention relates to the technical field of positioning tags, and more specifically relates to a low-power consumption multi-mode positioning tag. Background technique [0002] According to Markets&Markets analysis, the global indoor positioning market will reach USD 4.4 billion in 2019 and exceed USD 10 billion by 2024. Deploying positioning nodes to periodically send broadcast signals is currently a mainstream indoor positioning implementation solution, which has the characteristics of high precision and low deployment cost. When using positioning nodes for indoor positioning, it is necessary to collect the broadcast information sent by the positioning nodes through positioning terminals or positioning tags. However, the current positioning tags consume a lot of power, have short battery life, and require frequent battery replacement or charging, which is extremely difficult in actual use. inconvenient.
