Combining AI with OCR and License Plate Recognition to Build Traceable Logistics Records for Chemical Tanker Trucks
Combining surveillance cameras with AI video analytics and system integration to digitize the entire process has become a key application driving smart management and Industry 4.0 adoption.
Drawing on years of surveillance integration experience, Pro-Link used the VCA AI Bridge equipped with Vaxtor's highly accurate license plate recognition and OCR technology, with the Helix platform serving as the system's integration hub, connecting data from across the site,to successfully help a full-service semiconductor logistics center spanning transportation, warehousing, and technical services complete its digital transformation.
A chemical tanker entry/exit process that once required manual logging is now recognized and logged automatically in real time by AI, not only improving logging efficiency but also data accuracy, making later lookups and traceability far more convenient.
Moving Chemical Tanker Management from Manual to Digital
Many chemical tanker management processes today still rely on manual paper logging, which in practice runs into a number of common issues:
- Missed, mistaken, or duplicate entries
Manual entry is error-prone, and illegible handwriting adds difficulty to later review. - Inaccurate timestamps
During busy periods, it's common for a tanker to leave before the record is logged. - Difficult to standardize
Different staff have different habits and formats, making it hard to consolidate records consistently. - Lacking real-time visibility
When data needs to be submitted to regulatory authorities, it still requires additional manual data entry. - Time-consuming to search and trace
When a specific vehicle or incident needs to be traced, staff can only go back through paper records, and even with recorded footage, matching a plate number to a timestamp quickly is difficult.
In the past, when the contents of a tank were mismatched, just reviewing surveillance footage and paper records to confirm which trailer and which tank was involved could take half a day or more.
Building a Complete Logistics Traceability Record: Making Surveillance More Than Just "Watching Footage"
In petrochemical, chemical tanker, container logistics, port, and factory management settings, more and more companies are linking video with logistics data, letting surveillance systems not just capture footage but also build a complete data record in sync. Much like the concept of agricultural production traceability, logistics operations are now establishing traceable records for vehicles and containers.
Take chemical tankers as an example: on-site operations need to recognize not just the tractor's license plate, but also the trailer's plate, the chemical tank's side number, and its rear number. Since a tractor can be paired with different trailers at any time, without a complete data linkage, it's easy forthe wrong cargo or wrong tankto be delivered, and resolving such cases afterward consumes significant time and can even disrupt operations at the semiconductor facility.
Pro-Link deployed VCA AI Bridgeintegrating Vaxtor ALPR license plate recognition, OCR container number recognition, and the Vaxtor Helix platform, establishing and preserving a complete link between the tractor's plate, the trailer's plate, and the same chemical tank's side and rear numbers for every entry and exit.
When a chemical tanker enters the facility, the system instantly completes recognition and synchronizes all data to the Helix platform for review and management, allowing on-site staff to quickly confirm the corresponding vehicle, trailer, and tank information.
All entry/exit data is automatically created and stored by the system, reducing the after-the-fact corrections, omissions, or supplementary entries common with paper logging.
Even if a driver swaps tractors midway, the system can still automatically establish the complete data linkage. Whether it's an oil tanker, chemical tanker, or container truck, it can be automatically recognized and logged, reducing human error such as wrong cargo or wrong tank deliveries, and saving significant time on later traceability and lookups.
