Electronic tag based on motion sensor and radio frequency identification technology and energy saving method of electronic tag

Abstract

The embodiment of the invention provides an electronic tag based on a motion sensor and a radio frequency identification technology and an energy saving method of the electronic tag. The electronic tag comprises a power supply unit, an MCU main control unit, a wireless transceiver unit, the motion sensor, a radio frequency identification chip and a loop on-off detection unit. The power consumption of a transfer link can be reduced, and the single-time service life of the active electronic tag under the same battery capacity is prolonged.

Description

technical field [0001] The application relates to the field of electronic tags, in particular to an electronic tag based on a motion sensor and radio frequency identification technology and an energy-saving method thereof. Background technique [0002] In the fields of warehousing, security, logistics, etc., active electronic tags are used in scenarios such as item and personnel identification, status monitoring, and tracking. Most of these electronic tags are powered by batteries. In order to increase the life time of tags, motion sensors are widely used in active electronic tags to reduce the power consumption of tags in a static state. The main principle is: when the tag is moving, the parameters collected by the motion sensor exceed the set threshold and trigger the wake-up signal to wake up the tag to enter the wake-up state. In this state, the wireless transceiver unit sends information frequently, and the tag consumes high power. When the tag is still, the parameters...

AI Technical Summary

Problems solved by technology

[0004] 1. This type of tag is frequently awakened due to movement during the transfer link, and there is still the disadvantage of high power consumption;

[0005] 2. The identification method of the electronic tag is single, and the identification of the electronic tag becomes difficult when the battery is insufficient or the appearance is worn out;

[0006] 3. Traditional active tags have no loopback detection circuit. After the tag is separated from the corresponding associated object, there is no active report alarm, which reduces the safety and reliability.
