RFID Warehouse System

In today’s fast-paced environments, effective inventory management is crucial for efficiency and accuracy.
Recognizing the limitations of existing solutions, our company developed a sophisticated cabinet system designed to streamline the process of managing clothing (and not only) inventories.
By integrating advanced hardware, intuitive software, and innovative design, we’ve created a solution that addresses common challenges in inventory management while providing an exceptional user experience.

Why We Created Our Solution?

Existing inventory management solutions often fell short in areas such as reliability, security, and user-friendliness. While some systems offered basic functionality, they lacked the advanced features needed to handle complex inventory tasks, particularly in environments with high turnover rates or stringent security requirements.
Our cabinet system combines state-of-the-art hardware with robust software to deliver a comprehensive inventory management solution.

 

Hardware Features

Faraday Cage Design

Cabinets are constructed as Faraday cages to isolate RFID signals and prevent cross-detection, ensuring that only items inside a cabinet are detected.

Door Design

Since wood does not block electromagnetic waves we coated the inside of the cabinets with a special alloy. As a result, the waves do not escape, but this created a problem where the forces acting on the cabinet from the outside and inside became unbalanced, causing the walls to bend. To prevent this effect, we turned to physics and calculated the optimal number of holes that needed to be drilled to reduce the external force. The distance between these holes is equal to 1/100 of the wavelength, which prevents radiation from escaping while balancing the forces.

Antennas

Placed under plates at the top and bottom of the cabinets to generate the necessary RFID waves for tracking.

RFID Sensors

Integrated into the cabinet’s structure for precise and reliable item tracking.

Electromagnetic Locks

Secure cabinet doors, monitored by contact sensors to ensure they are properly closed.

Software Features

System Integration

Seamlessly connected with the company’s external app, allowing centralized management and real-time updates.

User Roles

Ordinary User

Basic access for standard operations.

Refiller

Responsible for restocking, with access to settings for scanning, notifications, and brightness/volume controls.

Service Personnel

Full access to all functionalities, including maintenance tasks and system configurations.

Technology and Solutions Implemented

    Innovative Technologies:

    • Faraday Cage Technology: Ensures secure, interference-free RFID tracking within each cabinet.
    • LIDAR Technology: Used in return cabinets to measure fill levels, triggering notifications when capacity thresholds are reached.
    • RFID Counting Modes: Offers two modes—memory mode (tracks all items ever placed) and current mode (tracks only current items).

    Integrated Solutions:

    • Seamless Communication: Between our system and the external management app, enabling efficient and accurate inventory management across multiple cabinets.
    • Optimized Power Management: Allows multiple cabinets to share a single power source, reducing the need for excessive wiring.

    Testing and Challenges

    Throughout the development process, we encountered several challenges, particularly related to the structural integrity of the cabinets and the reliability of RFID signal isolation.

    Challenges Encountered and Solutions Implemented:

    Signal Leakage:

    Problem Solution
    Due to varying forces exerted on the doors from both inside and outside, their tendency to warp compromised the system’s effectiveness. A special material was applied to the inside of the cabinets to block radiation leakage while maintaining a visually appealing.

     

    Door Bending:

    Problem Solution
    Due to varying forces exerted on the doors from both inside and outside the cabinets, they tended to warp, compromising the system’s effectiveness. Holes were drilled in the doors at specific intervals to prevent wave leakage and effectively counteract the bending issue.

     

    User-Friendly Interface and Software

    The system's software is powerful and user-friendly, with a customizable web-based interface running on an embedded Linux platform, developed using Node.js and C for responsiveness and reliability.

    Seamless Integration with Cloud Services

    Fully integrated with cloud software, the system automatically syncs data and offers real-time inventory tracking through a Linux-based web interface, improving efficiency and reducing errors.

    Advanced Security and Flexibility

    Security is ensured with RFID readers that verify encrypted credentials, allowing access only to authorized users and supporting multiple RFID standards for versatility.

    Modular and Scalable Architecture

    The modular system easily scales from small setups to large networks, with cabinets daisy-chained via Ethernet for simplified installation and reduced need for external switches.

    Battery Backup and System Redundancy

    The system includes battery backup for power outages, with Ethernet-powered cabinets to maintain operation, ensuring no data loss and continuous functionality even if main power supply fails.

    Robust Design with Intelligent Features

    Designed for industrial use, the cabinets feature heavy-duty components and lidar sensors for accurate content measurement, automatically alerting operators when needed.
