METHOD AND SYSTEM FOR POWER MANAGEMENT OF ASSET TRACKING SYSTEM FOR NON-STATIONARY ASSETS
First Claim
1. A radio frequency identification (RFID) tag comprising:
- an accelerometer, configured to communicate an acceleration reading of the RFID tag; and
a microcontroller unit (MCU), configured to transition the RFID tag through one or more states, and operably connected to the accelerometer, wherein the MCU is further configured to;
awaken, based on a trigger;
receive, from the accelerometer, the acceleration reading of the RFID tag;
calculate, based on the acceleration reading of the RFID tag, whether the RFID tag is in motion or not; and
if the RFID tag is in motion then;
transition to an in motion state.

Abstract
There is system for power management for radio frequency identification (RFID) tag asset tracking systems where the tag has a transceiver, configured to control RFID communication of the RFID tag, an accelerometer, configured to determine and communicate whether the tag is in motion and a microcontroller unit (MCU), to control operation of the RFID tag and operably connected to, and in communication with, the accelerometer and the transceiver, wherein the MCU awakens, based on a trigger and receives, from the accelerometer, whether the accelerometer is moving, and if it is moving then provide power to other parts of the tag, otherwise transition to a sleep mode to conserve power.
