Process

WiFi: Primary protocol for real-time monitoring.
Bluetooth: Optional for short-range, low-power communication.
Zigbee: Optional for mesh networking capabilities.
Cellular: Hub uses cellular communication for data transmission in areas without WiFi.

Base Station: A small Linux box with MQTT over WiFi collects data from the IMU.
Outdoor Router: Ensures connectivity in various environments.
Software: Includes applications for data analysis and alert management on Linux or Windows PCs.

Data Acquisition: Continuous real-time data collection by the IMU.
Preprocessing: Removes noise and drift using filters.
Segmentation: Identifies regions of interest based on detected events.
Feature Extraction: Extracts key features like peak acceleration and impact duration.
Event Detection: Detects significant events by comparing features against thresholds.
Summation and Cumulative Analysis: Assesses cumulative effects of multiple impacts.
Alert Generation: Generates alerts if cumulative impact exceeds safety thresholds.
Data Transmission: Sends processed data and alerts to the base station.
Visualization and Reporting: Provides insights into impact patterns and potential risks.

Alert Message: “We measured a high signal or a summation of hits. Please check them out.”
Alert Criteria: Based on NIH data, alerts are triggered for impacts over 2Z.
