License plate recognition to control the vehicles on the scales and in the yard
The truck rolls into the yard, and even before the driver reaches the scale, EWA System who’s coming. License plate recorded, master data loaded, weighing screen filled out. That’s what ESSMANN’s license plate recognition is designed for: for vehicle scales at entry and exit points and, beyond that, for comprehensive yard management.
License plate recognition uses ANPR (Automatic Number Plate Recognition) technology to capture the license plate upon entry. This reliably distinguishes between registered vehicles and visitor vehicles, and pre-scheduled weigh-ins proceed automatically without any user intervention. In our EWA system , the EWA Vision module in the EWA Suite cross-checks the license plate against your master data and fills out the weighing form before the driver reaches the scale. Loading specifications—such as those for handling waste, hazardous materials, or construction materials—are stored in the system and are also verified during this process.
The precise motion detection also enables the exact position of the vehicle to be determined, which is crucial for smooth weighing or loading.
Via a driver self-service direct instruction for the next job is also possible.
Automatic license plate recognition and vehicle identification speeds up the vehicle management process by reducing the time required for manual data entry prior to weighing. Drivers and weighers benefit from shortened and simplified processes when entering master data or comparing data. License plate recognition and multilingual processing enable the automation of processes such as vehicle tracking and access control on the factory premises.
License Plate Recognition and Data Protection
A license plate is personal data. License plate recognition therefore processes personal data, and your data protection officer will ask about this. We’ll work with you to determine what data is collected, how long it will be stored, and when it will be deleted, and we’ll document camera positions and coverage areas for your record of processing activities. We’ll clarify this during the project planning phase—not in the fine print.
