BLE Indoor Positioning System

Description

The BLE Indoor Positioning System is a complete solution for locating and tracking personnel and assets within indoor environments using Bluetooth Low Energy (BLE) technology. The system works by placing BLE scanners at fixed locations throughout the indoor environment that detect signals from BLE beacons carried by users. Each scanner captures RSSI (Received Signal Strength Indicator) values from nearby beacons and transmits this data to a centralized server, which calculates the position of each beacon in real time. The system includes a full-featured web interface with dashboard, floor plan management, real-time tracking, and path history for comprehensive indoor monitoring.

Key Features

• Real-Time Indoor Tracking: Locate and monitor personnel and assets in real time across multiple floors.
• BLE Beacon Technology: Small, battery-powered beacons transmit signals for position estimation via RSSI trilateration.
• Multi-Scanner Network: Fixed BLE scanners placed at strategic locations capture signal data from all beacons in range.
• Web-Based Dashboard: Comprehensive admin interface showing users, beacons, receivers, location history, and usage statistics.
• Floor Plan Management: Upload and manage custom floor plan images with drag-and-drop scanner placement.
• Path Tracking: Trace historical movement paths of tracked users with configurable time spans.
• Real-Time Visualization: Live display of beacon positions overlaid on floor plans with zoom and pan controls.
• Wi-Fi Hotspot Configuration: Easy scanner setup via built-in hotspot mode and browser-based credential entry.
• User & Beacon Management: Add, assign, update, and delete users and beacons through the web interface.
• Multi-Floor Support: Supports tracking across multiple floor levels simultaneously.
