EVENT DETECTION SYSTEM AND METHOD FOR REAL-TIME INVENTORY MANAGEMENT SYSTEM

A method and system of detecting events and updating inventory data in an inventory management system. The system is configured to sense and monitor inventory levels at one or more inventory locations, each having a load sensor that is configured to sense the weight of inventory items at the inventory location and generate a representative sensor signal. The system receives a digital signal having data samples that represent the sensor signal and moves those through a data buffer. The system generates a moving gradient value representing an average gradient from a moving gradient window applied to at least some of the data samples in the data buffer and compares the generated moving gradient value to one or more thresholds to detect the start and end of events. The system then generates output event data comprising at least weight data representing the inventory level following the detected event.
