Inventory management method and system with synchronized shelf devices and sensors activation

Abstract

The invention relates to an inventory management method which comprises the steps of: controlling shelf devices (AID) arranged on shelves of a fixture to cause the shelf devices to implement a localization process: controlling a sensor (CAM) to acquire sensor signals during the localization process: and localizing each of said shelf devices based on the acquired sensor signals. Controlling the shelf devices comprises sending a device command (D-Cd) to each of said shelf devices (AID), wherein the device command includes a localization process execution time and causes each of said shelf devices to have been switched from a sleep mode (SLPd) to a wake-up mode (WU-BLK) at the localization process execution time and to emit a localization signal before switching back to the sleep mode. Controlling said sensor comprises sending a sensor command (C-Cd) to the sensor (CAM), wherein the sensor command includes the localization process execution time and causes the sensor to have been switched from a sleep mode (SLPc) to a wake-up mode (WU-CAP) at the localization process execution time and to capture the localization signal emitted by each of said shelf devices before switching back to the sleep mode.
