Baggage Handling System (BHS)

The following is an introduction of Incheon International Airport's baggage handling system.

Baggage handling system (BHS)

The newly implemented next-generation BHS technology will secure the world's top level precision and efficiency.
Phase 4 BHS overview
  • Full length 49㎞ (30 mile)
  • Capacity 3,000
  • Auto-sorter 4units

Phase 3 vs phase 4 comparison

Phase 3 ICS TYPE

Baggage sorting by independently moving trays

Characteristics

2,700/hour per loop

Accurate tracking of baggages

ICS: Individual Carrier System

Integrated security inspection of baggages for departure and transfer
Sorter Transfer Security Check-in Security
Baggage sorting TTS TYPE

Baggage sorting by the auto-sorter on repeated loops

Characteristics

5,400/hour per loop (high capacity)

Simple system composition and superb responsiveness to malfunction

TTS: Tilted Tray Sorter

Separation of baggages for transfer and security inspection with specialized equipment
Sorter Security
Check-in Sorter Security
Fast and accurate baggage handling

Once the 49km system is completed, an extensive system with the full length of 190㎞ is established. 190㎞ is roughly the distance of making two round trips between Incheon Airport and Seoul. Despite its complexity, the system can handle baggages quickly and accurately. In addition, the system uses explosive detection equipment integrated in lines with the BHS to inspect all baggages with speed and thoroughness.

Features of BHS from phase 4

Application of innovative technologies for advanced baggage service
Improved Baggage Reading Rate Baggage tag reading through optical character recognition (OCR)
Workspace improvement Operation assistance facilities for preventing worker injury
  • Camera-based ATR
    (Automatic Tag Reader)
  • The camera shoots baggage tags, and baggage data are searched through OCR that reads text on tags such as “for flight” and “for lateral.” * OCR: Optical Character Recognition
    Strengths

    Improved recognition rate compared to the existing laser method

    Excellent responsiveness to malfunction in computers and networks

  • Operation assistance equipment
  • Equipment that protects the bodies of workers handling heavy baggages and improves operation efficiency
    Strengths

    Prevention of muscloskeletal disease in workers

    Prevention of damage and injury due to fall of baggages

    Utilization of BRS, etc. through bag tag recognition
