ACCESSMILE BCT Pilot – scales calibration

Date: 04.02.2025
In December the instalment of the BCT scale system was completed by the supplier – local Polish company DuoRS Gdańsk. The integration works connecting scale software without Terminal Operating System has also just finished and BCT proceed with testing phase.

After loading at terminal truck passes through the OCS exit gate with normal speed (10-30 km/h) where cameras capture the registration plate and merge it with container exit transaction. The scale measures the gross weight of whole track and gives the weight pressure per each axle of the vehicle. System compares with the legal limits. In case all is OK truck continue it way to main gate. But when register of overweight then it directs the truck to trouble area. If the special overweight circulation permits are in place the truck is released from the terminal to public roads. If not, it is turned back to the container yard for discharge.

As this is the first implementation of this technology in the ports, the main challenge is special tuning and calibration of scales in order to consider all unfavorable weather conditions and surface little vibrations coming from the container yard which is nearby. The special algorithms have to be created taking into consideration all external factors having the influence on the sensors and how to eliminate their negative impact.

After January tests witch gave unsatisfactory results, the supplier decided to install some additional weight and temperature sensors helping in definition of all variables having even very little effects. The new round of testing is going is planned for March and the go-live of the whole project was postponed to end of April/ beginning of May 2025.
