1. Background

With the rapid development of the logistics industry, efficient and accurate automatic parcel sorting has become critical to improving warehouse efficiency. This solution aims to build a fully automatic, high‑fault‑tolerance parcel identification and label printing system using high‑performance automatic scanning equipment and supplementary code‑scanning tools, solving the pain points of low efficiency and missed scans in manual sorting.

2. Core Hardware Components

2.1 ED3009 Industrial Fixed Mount Barcode Scanner

• Core Function: Installed at the top of the sorting line for automatic recognition of QR codes on parcel surfaces.
• Technical Advantages: High frame rate capture, perfectly compatible with high‑speed moving sorting lines; equipped with powerful error correction algorithms to read damaged, distorted or low‑contrast barcodes.

• Industrial Design: IP67 dustproof and waterproof rating, suitable for harsh warehouse environments.

• 
  

2.2 ED1080 High‑Speed Thermal Label Printer

• Core Function: Prints sorting labels and express waybills after sorting.
• Performance Parameters: 150mm/s high‑speed output, 203 DPI resolution, ensuring clear and readable printing content.

• Application Value: Supports batch continuous printing; built‑in power supply simplifies workstation wiring.

• 
  

2.3 D46 Omnidirectional Desktop Barcode Scanner (For Supplementary Scanning)

• Core Function: Placed on the workbench as the second line of defense for the automatic identification system.
• Technical Features: Dual‑CPU architecture, ultra‑large scanning window, supports omnidirectional fast scanning without deliberate focusing.

• Supplementary Role: Manually and quickly re‑scan parcels at special angles missed by the automatic scanning gate.

• 
  

2.4 W48 Wireless Handheld Barcode Scanner (For Flexible Supplementary Scanning)

• Core Function: Used by operators to handle loose cargo or large parcels outside the automatic line.
• Technical Features: 2.4G wireless transmission, supports 100‑meter long‑distance communication; 2000mAh large‑capacity battery for all‑day high‑intensity operation.

• Application Scenario: Flexibly handle missed scans and prevent parcels from entering wrong sorting areas.

3. System Workflow

1. Task Issuance: WMS/ERP system sends sorting tasks to the central control system.
2. Automatic Identification: Parcels pass through the sorting gate, and the overhead ED3009 automatically identifies QR codes and transmits data to the system.
3. Abnormality Judgment: If ED3009 fails to identify the parcel, the system triggers an alarm for supplementary scanning.
4. Manual Supplementary Scanning: The operator uses desktop D46 or wireless handheld W48 to manually re‑scan, ensuring 100% collection rate.
5. Label Printing: After successful identification, ED1080 automatically prints the corresponding sorting/packaging label to complete the labeling process.

6. Data Closed‑Loop: Sorting completion data is transmitted back to the backend system in real time, and the task is closed.
