Case Detail

RFID Emergency Repair Tool Box Project at a Railway Power Supply Section

By combining a warehouse management system with RFID security gates, handheld terminals, and 2.4 GHz light-and-sound tags, every repair tool and material gets a unique identity, enabling inbound and outbound registration, fast inventory counting, and light-guided locating of a specific item.

Client Background

The emergency repair base of a railway power supply section handles the daily preparation, issue, return, and emergency support of power repair tools and materials. Repair assignments place high demands on tool completeness, material issue records, and on-site return verification.

As the variety of tools and materials grew, manual registration and counting showed clear limits: issue records were unclear, returns were hard to verify, physical quantities did not always match the checklist, and items left behind on site were not easy to spot in time.

Project Challenges

Overlooked tools are hard to spot in time

After a repair assignment, staff must quickly confirm whether every tool and material has been brought back; checking item by item by hand easily misses something.

Issue and return records are not clear enough

Manual registration cannot keep accurate, continuous records of what was taken out, what was returned, and the current status of each item.

Reconciling physical stock with the checklist is heavy work

The actual contents of an emergency repair box must stay consistent with the system checklist, and manual reconciliation is prone to mistakes.

Finding a specific item takes time

When a particular tool or material is needed, staff want to locate and pick the right item quickly.

Solutions

The project combines a warehouse management system with RFID security gates, RFID handheld terminals, RFID desktop issuers, 2.4 GHz readers, light-and-sound tags, a laser printer, and a TV display wall, giving every tool and material a unique identity and record.

Inbound, issue, and return steps generate business records through the system and RFID devices, reducing reliance on manual registration. On site, RFID handheld devices support counting and reconciliation, helping reveal differences between physical quantities and the system checklist.

When a specific tool or material is needed, staff select the target item in the system; the 2.4 GHz reader and light-and-sound tag work together to give a light-and-sound cue that helps staff locate it faster.

Unusual treatment

Find a designated item with light-guided locating

When staff need to find a specific repair tool or material, they select the target item in the system. The 2.4 GHz reader triggers the matching light-and-sound tag, whose light and sound cues help staff find the target quickly.

This makes the tool-finding step more direct and reduces repeated searching across rows of workstations and tool racks.

Key Functions

Unique Item Identification

Each tool or material gets its own identity and system record, so items and records map one to one.

RFID tag management

Supports label printing, encoding, binding, verification, and reprinting or replacement, giving tools and materials an RFID identity that can be read directly.

Inbound and outbound registration

Records inbound, issue, and return events for tools and materials, forming a queryable ledger.

RFID fast-track inventory

RFID handheld devices help reconcile physical items on site against the system checklist.

RFID security gate identification

Identifies movements of repair materials through the area entrance and logs the events, reducing manual registration.

Light-guided item locating

2.4 GHz readers and light-and-sound tags help locate a designated item and guide staff to the target.

Exception alerts and handling

Raises alerts for overdue returns, inventory discrepancies, and mismatches between physical items and the checklist, so staff can follow up promptly.

Data display

The warehouse management system and the TV display wall present material and business data.
