What Makes a Weighbridge Automatic?

The traditional weighbridge experience often involves an operator manually recording vehicle details, directing the driver onto the platform, and painstakingly entering weight data after the vehicle exits. Automatic weighbridges, on the other hand, leverage a suite of technologies to transform this process into a smooth, self-service experience.

At the heart of automatic weighbridge operation lies Automatic Vehicle Identification (AVI). This technology eliminates the need for manual data entry by identifying incoming vehicles.  There are two main AVI technologies used:

  • Radio Frequency Identification (RFID): Vehicles are equipped with RFID tags that emit a unique signal when they come within range of the weighbridge reader. This signal transmits pre-loaded vehicle information, such as license plate number and tare weight (weight of the empty vehicle), to the weighbridge software.
  • Automatic Number Plate Recognition (ANPR): High-resolution cameras capture the license plate of the incoming vehicle. The ANPR system then uses optical character recognition (OCR) technology to extract the plate number and compare it to a database of authorized vehicles. This can also retrieve pre-associated tare weight information.

In addition to AVI, automatic weighbridges rely on a network of weight sensors embedded within the weighbridge platform. These sensors, called load cells, precisely measure the weight of the vehicle and its cargo as it traverses the platform. The weighbridge software receives the weight data from the load cells and, if applicable, combines it with the tare weight information retrieved from the AVI system. This allows the software to calculate the gross vehicle weight (total weight) and individual axle weights.

Generally, the weighbridge software acts as the brain of the entire operation. It processes data from both AVI and load cells, performs weight calculations, and often integrates with other logistics management systems. This integration allows for features like automatic generation of weight tickets, real-time updates to inventory management software, and seamless data transfer for regulatory compliance purposes.

How Does Weighbridge Automation Work?

The smooth operation of an automatic weighbridge relies on a well-coordinated interplay of technology. Here’s a closer look at the steps involved:

The smooth operation of an automatic weighbridge relies on a well-coordinated interplay of technology. Here’s a closer look at the steps involved:

  1. Vehicle Entry: As a vehicle approaches the weighbridge, Automatic Vehicle Identification (AVI) systems take center stage. These systems can employ either RFID tags pre-attached to vehicles or license plate recognition (LPR) technology. RFID tags emit radio signals that are picked up by readers near the weighbridge, instantly identifying the approaching vehicle. LPR systems, on the other hand, capture images of the license plate using high-resolution cameras and utilize software to recognize the plate number. This identification process eliminates the need for drivers to stop and manually interact with a booth operator, saving time.
  2. Weight Measurement: Embedded within the platform are load cells, essentially high-precision sensors that measure the weight applied to them. As the vehicle drives onto the platform, the load cells capture the weight data for each axle and the entire vehicle itself. This data is then transmitted electronically to the weighbridge software for further processing.
  3. Data Processing: The weighbridge software acts as the brain of the operation, receiving the weight data from the load cells. It then performs crucial calculations, determining the weight of each axle and the total weight of the vehicle. In some cases, the software might also retrieve pre-loaded information about the vehicle based on the AVI identification. This could include details like the vehicle type, carrier company, or expected cargo.
  4. Data Recording & Integration: The collected and processed data doesn’t disappear after a single weighbridge pass. The software stores the weight data electronically, often including timestamps and the unique identifier obtained through the AVI system. This electronic recordkeeping ensures easy access to historical data and simplifies compliance with regulations that might require weight documentation. Additionally, the software can be integrated with other logistics management systems within a business. This allows for automatic weight ticket generation, updates to inventory management software, or seamless data transfer for further analysis.

By automating these steps, automatic weighbridges not only expedite the weighing process but also eliminate the potential for human error in data entry and weight calculations. This translates to faster processing times, improved accuracy, and valuable data insights for businesses.
