Mission

Eliminate theft, loss
and human error at weighing stations.

Metrici Weighing Module started by fulfilling client needs to automate their processes and provide AI-based help to reduce thefts, losses, or human errors so often involved in man-powered processes.

Initially, the weight was synchronized with the license plate. Following requests from clients, new features were added, such as allowing access only to vehicles on whitelists. Also, Metrici introduced a system to check and compare the weight from the entry and the one from the exit to ensure there are no deviations beyond a certain percentage.

In the first introduction of the setup, hardware sensors were used, such as laser sensors to detect when a vehicle approaches a weighing station or if it is properly placed with all wheels on the station.

Solution

Fully AI-driven.
No hardware sensors required.

Metrici developed its AI with new features so it can entirely base on its own capabilities to recognize different situations and objects. A new add-on was recently developed so Metrici does all the job and no additional hardware is necessary — only optional — for full automation of a weighing process.

The solution is based on Metrici software — AI-based License Plate Recognition and Parking Place Detector modules working together to deliver the best results. Adapted and suited for industrial parks, factories, production facilities, storage units, and transportation companies.

Integration with any type of industrial weighing scale is achieved through a specially developed firmware for the Barix Barionet, and also with any other external systems or management software.

The very first installation using this solution was made at one of the biggest ballast pits in Romania, with heavy traffic in and out. The integrator was one of Metrici's long-time collaborators, Power Solutions, which chose to work with Metrici software and Axis cameras to deliver the best setup for the client.

      Metrici managed to fully automate the weighing process. The solution relies entirely on Metrici's AI capabilities — License Plate Recognition and Parking Place Detector modules working in tandem — eliminating the need for external hardware sensors.
    

How the System Works

Step by Step · Virtual parking spots drive the entire process

Cameras monitor both the entrance and exit from the weighing station. A Metrici Parking Place Detector engine watches virtual parking spots strategically placed on the station. With just settings for each one, the system is operational.

STEP 01

Vehicle Approaches

When a virtual parking spot is "occupied" — meaning the vehicle is moving and approaching the station — Metrici detects it and sends a command to open the barrier for the car to be placed on the station.

STEP 02

Vehicle on Station

The vehicle moves forward and occupies another virtual parking spot, this time when it stops on the weighing station. The PPD engine detects the vehicle and confirms it is properly aligned on the station.

STEP 03

LPR Reading & Weight Capture

PPD sends a trigger to the Metrici LPR engine to start detecting the number plate. When the plate is read, Metrici also records the weight from the weighing station simultaneously.

STEP 04

Event Recorded

All events are recorded in the database and can be filtered in the Metrici Interface. Each weighing line typically has two virtual parking spots, so depending on which one is busy, Metrici knows what action to take.

STEP 05

Alarm Configuration

Settings are configured in the Metrici Interface, under the Parking Place Detector menu, Alarm sub-menu. You set an alarm for each spot: when one is "busy", command the barrier to open; when the other is busy, trigger LPR reading and record the event.

OPTIONAL

Traffic Lights & LED Displays

Additional installations may include traffic lights or LED displays. These show different messages and indications for the driver and can signal when the car is properly aligned on the station.

Integration with any type of industrial weighing scale is supported through a specially developed firmware for the Barix Barionet. The system also integrates with external management software and can be adapted to any industrial environment.

Results and Benefits

Full transparency.
Every weighing event tracked.

Metrici installations for weighing stations help clients eliminate losses, theft, and human errors. All events are recorded, filterable, and reportable.

🛡️

Eliminated losses and theft

Automated weight verification at entry and exit detects any deviation beyond a configurable percentage, preventing material theft.

📋

Complete event logging

All weighing events are recorded in the database with license plate and weight data, fully filterable through the Metrici Interface.

📊

Statistics and reports

Full access to different statistics and reports regarding the activity at the location, enabling data-driven operational decisions.

🔔

Configurable alarms

Set alarms for different scenarios: specific license plates, weight deviations, long stays, or whitelist violations — all configurable in the interface.

Metrici's fully software-based approach means no additional hardware sensors are required — just cameras, the Metrici engines, and the Barix Barionet for scale integration. The system is proven in the field, with the first installation operating at one of Romania's largest ballast pits, handling heavy daily traffic.
