▲UHF gate makes it easy to monitor forklift operation status! Reduce the burden on workers with long range scans

Mars Tohken proposes UHF band RFID solutions to promote inter-process automation and IoT in Thai factories. UHF band is one of the frequency bands for RFID using Ultra High Frequency (UHF), which is widely used for inventory control and product inspection due to its long communication distance and suitability for batch RFID reading.

Mars Tohken's UHF band RFID-based "Automatic inter-process transfer control system" uses UHF band IC tags attached to trolleys (AGVs) that come and go in the factory to enable automatic transfer to the next process line corresponding to the production item.

Benefits of deploying UHF band RFID solutions

1. Improved accuracy of destination management and instructions for parts transportation (prevention of human error).
・ Automatic transport is possible by attaching a UHF band RFID tag to AVGs.
・ Because it is managed by RFID, human error due to manual input can be prevented.

2. Labor saving
・ It is possible to change the AGV driving line and eliminate the time lag and waiting time between parts request delivery.
・ It can also be applied to forklifts and materials-supplying-runners (* workers who supply materials required for each process).

3. Utilization for location / transit management (visualization)
・ UHF band RFID tags attached to pallets, containers, etc. enable real-time location management.
・ It is possible to establish process management and inventory management.

▲ Operation flow

Parts warehouse
・ Link the parts box numbers to the parts information.
・ Link the trolley numbers to destination (line) information.
・ Read the trolley numbers and indicate the destination to the AGV, etc.

Production line
・ Install UHF band RFID reader/writer and antenna on each line.
・ Parts request can be made in real time from a panel computer (tablet terminal).
・ Read the number of the trolley received from the parts warehouse and indicate the destination to the AGV, etc.

UHF band RFID compatible products required for automated transport construction

The following is an example of Mars Tohken's UHF-compatible RFID products.

Self-driven fixed UHF band RFID reader/writer "FRU-4000Plus / FRU-4025Plus”

This is a self-driven fixed UHF band RFID reader/writer with simple settings that is available in two models: a specified low-power model that does not require a radio station application or a premises radio station (licensed station). No control PC is required in auto mode. Immediately after turning on the power, the IC tag is automatically read and data is transmitted.

UHF band RFID tag

We have prepared many UHF band compatible IC tags that enable long-distance communication.
・ High heat resistant type metal compatible tags (for metal pallets, molds, etc.)
・ Tags for carts (for car trucks and trolleys)
・ Curved surface tracking soft case type (for pail cans, drum cans, etc.)
・ Global type (for metal racks for international logistics), etc.
